ABOUT NTIS
As a cornerstone of the technological publishing structure in
the United States, the National Technical Information Service
(NTIS) is a key participant in the development of advanced
information products and services for the achievement of U.S.
productivity and industrial innovation goals in the 1980's.
NTIS, an agency of the U.S. Department of Commerce, is the
central source for the public sale of U.S. Government-sponsored
research, development, and engineering reports, and for sales
of foreign technical reports and other analyses prepared by
national and local government agencies and their contractors
or grantees.
And, it is the central source for:
federally generated machine processable data files
and software;
licensing U.S. Government-owned patents.
NTIS manages the:
Center for the Utilization of Federal Technology
(CUFT), which alerts U.S. industry to specially select-
ed technology having immediate practical value;
Federal Software Exchange Center, for the exchange
of computer software among Federal agencies, with
public availability through NTIS.
Consequently, NTIS is one of the world's leading processors
of specialty information.
The NTIS information collection is approaching two million
titles, several hundred thousand of which contain foreign tech-
nology or foreign marketing information. All are permanently
available for sale, either directly from 80,000 titles in shelf
stock or from microform master copies of documents that are
less in demand. Annually, NTIS supplies its customers with
more than six million documents and microforms, shipping
about 24,000 information items daily.
Full summaries of current U.S. and foreign research reports
and other specialized information, in hundreds of subject cat-
egories, are published regularly by NTIS in a wide variety of
newsletters, journals, and indexes, and in a variety of sub-
scription formats for other Federal agencies. The complete
texts of the technical reports cited are sold in paper and
microform.
Some 70,000 new technical reports of completed research
are added annually to the NTIS Bibliographic Data Base. Any-
one seeking the latest technical reports or wanting to compile
unique subject groups of abstracts may search the NTIS Bibli-
ographic Data Base online using the services of vendors or
organizations that maintain the NTIS data base for public use.
The whole data base in machine readable form may be leased
directly from NTIS.
The more timely documents in the NTIS collection are selected
by category and sold as paperbound Published Searches,
covering some 3,000 topical subject areas.
Customers with well defined continuing interests may sub-
scribe to a standing order microfiche service (SRIM) which
enables them to automatically receive the full texts of only
those documents relating to their individual requirements.
NTIS sells its technical information products and services
under the provisions of Title 15 of the U.S. Code (1151-7). The
law established a clearinghouse for scientific, technical, and
engineering information within the Department of Commerce
and directed that it be self-supporting.
NTIS, therefore, is a unique Government agency supported
by its customers. All costs, such as salaries, manufacturing,
information acquisition, marketing and postage, are paid from
sales income; not from tax-supported congressional appro-
priations, certain developmental programs excepted.

The pump-and-treat process, whereby contaminated
ground water is pumped to the surface for treatment, is
one of the most common ground-water remediation
technologies used at hazardous waste sites. However,
recent research has identified complex chemical and
physical interactions between contaminants and the
subsurface media which may impose limitations on the
extraction part of the process. The report was devel-
oped to summarize the basic considerations neces-
sary to determine when, where, and how pump-and-
treat technology can be used effectively to remediate
ground-water contamination.

Aug 89,261 p EPA/600/6-90/008
The report is one of a series of reports that present
methodologies for assessing the potential risks to
humans or other organisms from the disposal or reuse
of municipal sludge. The sludge management prac-
tices addressed by the series include land application
practices, distribution and marketing programs, landfill-
ing, incineration and ocean disposal. In particular, the
reports provide methods for evaluating potential health
arid environmental risks from toxic chemicals that may
be present in sludge. The document addresses risks
from chemicals associated with landfilling of municipal
sludge. These proposed risk assessment procedures
are designed as tools to assist in the development of
regulations for sludge management practices. The
procedures are structured to allow calculation of tech-
nical criteria for sludge disposal/reuse options based
on the potential for adverse health or environmental
impacts. The criteria may address management prac-
tices (such as site design or process control specifica-
tions), limits on sludge disposal rates or limits on toxic
chemical concentrations in the sludge.

Surface impoundments are used to treat, store, and
dispose of wastewater generated by facilities in many
different industries. Because surface impoundments
are normally open to the atmosphere, the potential for
air emissions of volatile organic compounds (VOC's)
and toxic air pollutants exists. As such. State and local
air pollution control agencies need a methodology to
estimate the air emissions from surface impound-
ments. The Surface Impoundment Modeling System
(SIMS) is a personal computer based program de-
signed to estimate the air emissions from surface im-
poundments. The emission estimates are based on
mass transfer models developed by the Emissions
Standards Division (ESO) of the Environmental Protec-
tion Agency (EPA) during the evaluation of hazardous
waste treatment, storage, and disposal facilities
(TSDF's). SIMS allows the user to specify all the re-
quired inputs to these emission models when the infor-
mation is available, or when only limited information is
avaialble, provides default values for most of the
model inputs. The manual presents a complete refer-
ence for all of the features and commands in SIMS.
Another document entitled, Background Document for
the SIMS, PB91-156729, discusses the emission
models, surface impoundment design and operation,
default parameter development, and the emission esti-
mation procedure.

Center (CTC) and with project management provided
by EPA's Technical Support Division of the Office of
Air Quality Planning and Standards. SIMS is based on
emission models developed by the Emission Stand-
ards Division (ESD) during the evaluation of surface
impoundments located in treatment, storage, and dis-
posal facilities (TSDF). The purpose of the latest
update to SIMS is to add models for diffused air sys-

expand the compound database from 40 to 150. The
technical document discusses these emission models,
surface impoundment design and operation, default

ipal waste combustors (MWCs) to characterize or de-
termine the performance of representative combustor
types and associated air emission control systems in
the regulatory development process. Test results for
uncontrolled (combustor outlet) and controlled (flue
gas cleaning system outlet) polychlorinated dibenzo-p-
dioxins (PCDDs) and dibenzofurans (PCDFs) are re-
ported, along with pertinent information on other tests.
The EPA is revising air pollutant emission rules for new
MWCs and preparing guidelines for existing MWCs.
These rules will limit emissions of PCDDs, PCDFs,
CO2, and acid gases (HCI and SO2) as well as require
tighter control of particulate matter emissions.

The paper gives results of an examination of the cata-
lytic effects of copper and iron compounds for their be-
havior in promoting formation of chlorine (CI2), the
major chlorinating agent of polychlorinated dibenzo-p-
dtoxins (PCDDs) and polychlorinated dibenzofurans
(PCDFs), in an environment simulating that of munici-
pal waste fly ash. CI2 formed as a result of a metal-
catalyzed reaction of HCI with O2. Catalytic activity
was greatest at a temperature of about 400 C, support-
ing a theory of de novo synthesis of PCDDs and
PCDFs on fly ash particles downstream of waste com-
bustion.

Presented at the National Research and Development
Conference on the Control of Hazardous Materials,
Anaheim, CA., February 20-22,1991.
It has been well recognized that, although there are
many potential solid waste treatment technologies,
none are as universally applicable as incineration for
the treatment of the many types of waste which are
governed by the many different Federal laws and State
regulations. However, incinerators may release trace
amounts of unwanted combustion by-products, par-
ticularly if the incinerators are not well designed or
properly operated. Control of emissions of combustion
by-products (CBPs) is one of the major technical and
sociological issues surrounding the implementation of
incineration as a waste treatment alternative. Much of
this is due to the lack of detailed knowledge about
CBPs. The Clean Air Act Amendment is emphasizing
the control of toxic air pollutants from all combustion
sources; some of these pollutants are CBPs. CBPs in-
clude: (1) unbumed principal organic hazardous con-
stituents (POHCs); (2) products of incomplete combus-
tion (PICs); (3) metals emissions; and (4) residuals/
ashes. The Paper is a part of a series of writings on the
subject of the CBP issue from EPA's Risk Reduction
Engineering Laboratory in Cincinnati, Ohio. It specifi-
cally addresses the aspect of hazardous waste char-
acteristics. The main objective of the series is to com-
pare combustion by-products from all combustion
sources including fossil fuel combustion and waste in-
cineration, which hopefully will serve as an initial step
in the eventual minimization of the release of CBPs to
the environment.

The residents in Xuan Wei County, China, have been
exposed to high levels of combustion emissions from
smoky and smokeless coal and wood combustion
under unvented conditions in homes. An unusually
high lung cancer mortality rate that can not be attrib-
uted to tobacco smoke or occupational exposure was
found. The communes using smoky coal, which emits
more organics than smokeless coal, generally have a
higher lung cancer rate than the communes using
smokeless coal or wood. The mutagenicity and car-
cinogenicity of organic extracts of indoor air particles
collected from Xuan Wei homes during cooking were
investigated. The objectives of the study were (1) to in-
vestigate the characteristics of lung cancer mortality in
Xuan Wei, (2) to determine the genotoxicity and chemi-
cal and physical properties of the combustion emis-
sions, and (3) to link bioassay results to human lung
cancer data. The organic extracts of these emission
particles were tested for mutagenicity in the Ames Sal-
monella and the L5178Y TK+/- mouse lymphoma
assays and for skin tumor-initiating activity and com-
plete carcinogenicity in SENCAR mice. The two coal
samples whoed higher activity in both mutagenicity
and tumor initiation. When the emission rate of organ-
ics was taken into consideration, the smoky coal emis-
sion showed the highest potency of the three fuels.
The smoky coal sample was also a more potent com-
plete carcinogen than the wood sample. Higher muta-
genicity and carcinogenicity of the smoky coal emis-
sion compared to wood or smokeless coal emissions
are in agreement with the epidemiological data.

Presented at the Air Pollution Control Association
Annual Meeting (81st), Dallas, TX., June 20-24, 1988.
Review of permits for land disposal of hazardous
wastes requires numerous decisions concerning policy
and technical issues. Some require interpretation and
application of information in research reports, other in-
volve interpretation and evaluation of specialized test
data, and others involve assessment of compliance
with latest regulatory policies. Specialized knowledge
concerning a number of technical areas and a broad
base of environmental regulatory experience are nec-
essary to adequately perform these reviews. The need
for current knowledge and background, in addition to
the concern that reviews be consistent prompted the
authors int systems derest in expert systems. The
paper presents the history, current status, and future
direction of the expert evelopment program supported
by the Waste Minimization, Destruction and Disposal
Research Division of the Risk Reduction Engineering
Laboratory. The development methods being used

Data collection activities performed for the Risk Re-
duction Engineering Laboratory (RREL) of the U.S. En-
vironmental Protection Agency are divided into four
categories, depending on the intended use of the data.
Quality Assurance (QA) Project Plans are written to
ensure that project needs will be met and that quality
control procedures are sufficient for obtaining data of
known quality. The level of QA required, however, de-
pends on the project category selected for a given
project. Projects that produce results for the purpose
of evaluating and selecting basic options, or perform-
ing feasibility studies or preliminary assessments of
unexplored areas which might lead to further work are
identified as Category III projects. To assist profession-
al scientists and engineers in preparing QA Project
Plans, separate guidance manuals in an easy-to-read
format have been developed for each category. The
Category III manual contains detailed descriptions of
each of the 11 required elements of a Category III QA
Project Plan. Also included are definitions and expla-
nations of frequently used terms, examples of QA
forms and charts, sample equations and numerous
types of tables suggested for summarizing information.

Concern about the adverse effects of exposure to
Agent Orange is for the most part attributable to its
toxic contaminant, 2,3,7,8-tetrachlorodibenzo-p-dioxin
(TCDD). A total of 40 Vietnam veterans, 80 non-Viet-
nam veterans and 80 civilian men were selected from
males born between 1936 and 1954 and their adipose
tissues were analyzed for 17 2,3,7,8-substituted diox-
ins and dibenzofurans. TCDD levels were log normally
distributed and the mean level of 2,3,7,8-TCDD in adi-
pose tissue of the Vietnam veterans (13.4 ppt) was not
significantly different from that of the non-Vietnam vet-
erans (12.5 ppt) or civilian men (15.8 ppt). Adjusting for
demographic variables did not change the conclu-
sions. The study results suggest that heavy exposure
to Agent Orange for most Vietnam veterans was very
unlikely and that there is no readily available and reli-
able indirect method of assessing exposure to Agent
Orange for Vietnam veterans.

sored by EPA's Office of Marine and Estuarine Protec-
tion and the Gulf of Mexico Program, the workshop
was attended by 160 people representing many differ-
ent kinds of volunteer monitoring programs and gov-
ernment agencies from all around the country. A pri-
mary objective of the second national workshop was to
explore 'how to provide useful information and how to
encourage partnership between citizen monitoring
groups and state or regional government' A second
major objective of the workshop was to introduce state
and regional government officials to the achievements
and potential of volunteer monitoring. The third goal of
the conference was to provide an opportunity for par-
ticipants to meet and foster a national network of citi-
zen volunteers.

The problems facing the nation's estuaries do not fit
into existing conventional pollution control programs
based solely on regulations and enforcement. Neither
do they fit neatly into the traditional, restricted defini-
tion of 'water pollution'. Rather, they involve complex
issues of habitat protection, multimedia and nonpoint
source pollution, land-use planning, and resource
management. Congress established the National Estu-
ary Program (NEP) precisely to address these issues.
Under the Clean Water Act, the program is to show
how estuaries (and other ecosystems) can be protect-
ed and their living resources enhanced through com-
prehensive, action-oriented management that: identi-
fies the probable causes of major environmental prob-
lems in estuaries of national significance; promotes
and sustains long-term state and local commitment to
solving the problems; generates meaningful public in-
volvement and participation; focuses existing regula-
tory, institutional, and financial resources to act on
identified problems; and encourages innovative man-
agement approaches.

The purpose of the study is to evaluate the Urban
Airshed Model (UAM), a three-dimensional photo-
chemical urban air quality simulation model, using field
observations from the Tokyo Metropolitan Area. Em-
phasis was placed on the photochemical smog forma-
tion mechanism under stagnant meteorological condi-
tions. The UAM produced reasonable calculated re-
sults for the diurnal, areal and vertical distributions of
O3 concentrations covering the Tokyo Metropolitan
Area. The role and significance of the previous day's
secondary pollutants on O3 formation mechanisms
were also investigated. During the night time, high
values of secondary pollutant concentrations were
predicted above the radiation inversion layer. These
aged pollutants were then entrained into the mixing
layer during the day in accordance with the elevation
of the lid. These characteristic features were also ob-
served in the field study.

Investigations at Pinal Creek, Arizona, evaluated rou-
tine sampling procedures for determination of aqueous
inorganic geochemistry and assessment of contami-
nant transport by colloidal mobility. Sampling variables
included pump type and flow rate, collection under air
or nitrogen, and filter pore diameter. During well purg-
ing and sample collection, suspended particle size and
number as well as dissolved oxygen, temperature,
specific conductance, pH, and redox potential were
monitored. Laboratory analyses of both unfiltered
samples and the filtrates were performed by inductive-
ly coupled argon plasma, atomic absorption with
graphite furnace, and ion chromatography. Scanning
electron microscopy with Energy Dispersive X-ray was
also used for analysis of the filtered participates. Sus-
pended particle counts consistently required approxi-
mately twice as long as the other field-monitored indi-
cators to stabilize. High-flow-rate pumps entrained
normally nonmobile particles. Differences in elemental
concentrations using different filter-pore sizes were
generally not large with only two wells having differ-
ences greater than 10 percent in most elemental con-
centrations, although trends showed increasing con-
centrations with increasing filter pore sizes in most
wells. Similar differences (>10%) were observed for
some wells when samples were collected under nitro-
gen rather than in air.

from the study are: (1) the use of capture and control
systems and the use of water-based ink systems have
been demonstrated to be effective and reliable in
achieving greater than 90 percent overall VOC reduc-
tion rotogravure and flexographic printing facilities; (2)
facilities can be retrofitted to achieve 90 percent VOC

The purpose of the model documentation is to provide
a detailed description of the modeling and risk analysis
procedures used in CR-ERNS/PAM to assist OSCs
and other Superfund decision-makers in interpreting
the system results. PAM is a screening-level model; to
property interpret PAM's outputs, the user must under-
stand the limitations and uncertainties in the equations
and data used to generate these results. Chapter 2
presents the system's fate and transport models and
describes the assumptions associated with these
equations. Chapter 3 describes PAM's auxiliary data
bases and provides the source(s) of each parameter
and the methods by which values were selected.
Chapter 4 explains the methods and exposure as-
sumptions used to estimate exposures to hazardous
substances and to evaluate the risks and hazards as-
sociated with these exposures. Chapter 5 presents ex-
amples of reports generated by PAM and explains the

Soil vapor extraction (SVE) systems are being used in
increasing numbers due to many advantages these
systems hold over other soil treatment technologies.
SVE systems appear to be simple in design and oper-
ation, yet the fundamentals governing subsurface
vapor transport are quite complex. In view of the com-
plexity, an expert workshop was held to discuss the
state-of-the-art of the technology, the best approach
to optimize systems application, and process efficien-
cy and limitations. As a result of the workshop, an SVE
Technology Assessment report was produced. The
report discusses the basic science of the subsurface
environment and subsurface monitoring, emission
control, and costs. The report also serves as the pro-
ceedings of the expert workshop. Additional research
activities being conducted include a field demonstra-
tion of a structured SVE system design approach; a
laboratory column study to determine and characterize
residuals following vapor extraction; an assessment of
secondary emissions and regulations governing re-
leases from SVE systems; cost of SVE implementation
and operation; and a survey of techniques to enhance
vapor removal.

Atmospheric pollution is deposited on the forests of
the eastern United States in a variety of forms. Con-
cern has been raised that the exposure to and deposi-
tion of these atmospheric pollutants may play a role in
the decline of these forests. The Mountain Cloud
Chemistry Project (MCCP), sponsored by the U.S. En-
vironmental Protection Agency (EPA) and the National
Acid Precipitation Assessment Program (NAPAP), has
studied the exposure and deposition of atmospheric
constituents to these forests. Research scientists and
technicians of the MCCP have measured the concen-
trations of atmospheric pollutants at six remote moni-
toring stations for four growing seasons (1986-89).
Measurements of ozone, sulfur dioxide, oxides of nitro-
gen, hydrogen peroxide, doud and rain water ions, me-
teorotogfcal parameters, and other parameters of in-
terest were collected at sites in Howtand, ME; ML
Moosteuke, NH; Whtteface ML, NY; Shenandoah
Park, VA; Whftetop Mt, VA; and ML Mitchell, NC. The
report served to document the type and amount of
data collected for the Mountain Cloud Chemistry
Protect during the four warm seasons between 1986
and 1989. Details are presented on the locations of the
six research/monitoring sites, the types of measure-

EPA's Joint Emission Inventory Oversight Group is ini-
tiating research projects with the goal of better quanti-
fying air pollution emissions in both current and future
years. Highway vehicles have been found to be an im-
portant contributor to organic, oxides of nitrogen, and
carbon monoxide emissions as well as some hazard-
ous air pollutants, despite the significant emission re-
ductions that have already been achieved on a per ve-
hidebasis. Therefore, EPA is actively investigating re-
search opportunities to improve the state-of-the-art in
estimating highway vehicle emissions. The project was
an effort to solicit research ideas from people outside
EPA via a workshop forum.

to present general guidelines, criteria, and procedures
for indicator selection and evaluation, and (2) to estab-
lish an organizational framework for coordinating and
integrating indicator development and use within
EMAP. It should serve both to promote internal con-
sistency among EMAP resource groups and to provide
a basis for external review of the proposed indicator
development process.

In certain areas of the country where the National Am-
bient Air Quality Standard (NAAQS) for ozone is being
exceeded, additional measurements of ambient non-
methane organic compounds (NMOC) are needed to
assist the affected States in developing revised ozone
control strategies. Because of previous difficulty in ob-

monitoring and analytical assistance to these States,
beginning in 1984 and continuing through the 1990
NMOC Monitoring Program.

The report summarizes research performed by South-
em Research Institute on several aspects of the E-
SOx Process, invented by EPA to jointly control partic-
ulate matter and SO2 in coal-fired boiler emissions by
retrofitting an existing electrostatic precipitator (ESP),
formerly used only for paniculate removal. The report
covers research on potential ESP sites for process ap-
plication, process economics, characterization of proc-
ess solid waste collected in the ESP, measurement
and modeling of prechargers in the retrofitted ESP,
and effectiveness of the process with respect to SO2
removal. Experiment results described in the report
confirm original EPA laboratory work and were influen-
tial in the decision to proceed with a large pilot evalua-
tion of E-SOx. Research emphasis was on ESP per-
formance, under E-SOx conditions, to verify that this
essential equipment process component could retain
its primary function of particle removal at a level equal
to removal prior to modifications necessary for E-SOx.
Further research is suggested.

The report gives results of follow-up tests in 38 diffi-
cult-to-mitigate Pennsylvania houses where indoor
radon reduction systems had been installed 2 to 4
years earlier. Objectives were to assess system dura-
bility, methods for improving performance, and meth-
ods for reducing installation and operating costs. The
durability tests indicated that the 38 systems have not
experienced any significant degradation in indoor
radon levels or in system flows/suctions, except in 6
houses where system fans failed, and in houses where
homeowners turned off the systems. Tests to improve
performance indicated that nearly all of the elevated
residual radon levels are due to re-entrainment back
into the house of very-high-radon exhaust gas from the
soil depressurization systems, and to radon release
from well water. Tests to reduce system costs showed
that premitigation sub-slab suction field measurements
can help prevent installation of too many suction pipes
when communication is good, but suggest a need for
too many pipes when communication is poor. Soil de-
pressurization fans could not be turned down to the
extent expected in some systems that were over-de-
signed. Between 6 and 42% of the exhausted air was
withdrawn from the house.

Advanced oxidation processes are defined as those
which involve the generation of hydroxyl radicals in
sufficient quantity to affect water purification. The the-
oretical and practical yield of OH from O3 at high pH,
O3/H2O, O3/UV and H2O2/UV systems is reviewed.
New data is presented which illustrates the importance
of direct photolysis in the O3/UV process, the effect of
the H2O2:O3 ratio in the O3/H2O2 process, and the
impact of the low extinction coefficient of H2O2 in the
H2O2/UV process. (Copyright (c) 1987, International

Lake Lansing, Michigan was treated with sodium ar-
senfte for macrophyte control in 1957. Seven 1.5-m
sediment cores were taken along a line through the lit-
toral zone to the deepest portion of the lake and ana-
(yed for arsenic. In each core, arsenic concentrations
going from the surface downward increased to some
maximum and then receded to background. Depth of
peak concentrations followed two patterns; three litto-
ral cores showed peak arsenic at 0.13 m from the sedi-
ment surface, and four cores from progressively
deeper portions of the lake showed a regular decrease
in peak depth from 0.32m to 0.17m. Sediment accu-
mulation rates were calculated along this transect
Particle-size sorting of sediments along this slope was
also measured. This work suggested that i
originated from wetland vegetation at the edge of the
lake. Turbulent movement of water in the shallows
caused suspension and down-slope movement of
small particles. Fewer panicles of wetland origin were
available for sedimentation beyond the region of high-
est faHout (3.75 m), thus accounting for progressively
lower sedimentation rates in deeper portions of the
basin. A model was developed to predict the time it
would lake for surface sediments to reach pretreat-
ment concentrations of arsenic levels; for Lake Lan-
sing it would be more than 100 years. (Copyright (c)

The paper discusses the evaluation of electrostatic DC
corona discharge devices for the application of molec-
ular decomposition. A point-to-plane geometry corona
device with a rectangular cross section demonstrated
low decomposition efficiencies in earlier experimental
work. The numerical simulation of the device suggest-
ed that there were low electron density and electric
field zones, resulting in electrical sneakage. Thus, the
kinetic rate coefficients in the chemical reaction proc-
ess were significantly reduced. A triangle-shaped DC
corona discharge device was developed to improve
the electrical sneakage problem, and a mathematical
model was developed to describe the detailed electri-
cal characteristics and to refine estimates on the opti-
mum shape of the device. The preliminary experimen-
tal results indicated that the decomposition efficiency
was much improved.

A method for the determination of low molecular
weight aldehydes in water using aqueous-phase derivi-
zation with 0-(2,3,4,5,6-
pentafluorobenzyljhydroxylamine hydrochloride has
been improved by the use of high-resolution capillary
GC. Detection limits with GC/ECD and GC/MS with
selected ion monitoring are in the low mterogram per
liter (ppb) range. The method has been used to evalu-
ate levels of aldehydes in three surface water treat-
ment plants and one ground water treatment plant
before and after ozonation. Aldehydes are increased
as a result of ozonation, with formaldehyde being the
most prevalent Higher yields are observed in the plant
treating surface water with the highest TOC level, but
very low yields are observed in a high TOC ground
water. Spiking studies show that the raw ground water
has a very high demand for formaldehyde, suggesting
that the aldehydes may be converted into secondary
byproducts.

The article summarizes the views of aquatic scientists
who gathered to assess the ability of stream ecosys-
tem theory to predict recovery from disturbance. Two
views of disturbance were evident a discrete removal
of organisms vs an unusual deviation from normal.
These were perceived as applying to different scales
and/or objectives. Long-term information is required
from both points of view to define recovery. Recovery
also may be defined in different ways, but it is clear
that recovery has both spatial and temporal compo-
nents, and includes both physical and biological proc-
esses. There was strong consensus that a national
monitoring system of representative lotic ecosystems
within ecological regions be established. The purpose
of the monitoring system would be to acquire long-
term data on natural variability, to establish viable indi-
cators of spatial and temporal aspects of recovery,
and to develop and test emerging theoretical develop-
ments.

The effect of sintering on the reactivity of solids at high
temperature was studied. The nature of the interaction
was studied with calcium silicate-aluminate reacting
with SO2 between 665 and 800 C. The kinetics of the
sintering and sulfation processes were measured inde-
pendently in terms of the common variables, tempera-
ture and specific surface area. Surface reduction pa-
rameters were evaluated by the German-Munir sinter
model, modified to account for a strong catalytic effect
of H2O vapor. Sulfation parameters were determined
from a series of conversion vs. time measurements at
various temperatures using calcined solids of known
surface area. These show product layer diffusion
through CaSO4 to be the probable controlling process
above 670 C and diffusion through a mixture of CaSOS
and CaSO4 controlling below that temperature. Like
sintering, sulfation was enhanced by the presence of
H2O in the feed gas. With 7% H2O vapor, the en-
hancement factor for sulfation was 1.5 at 665 C and
estimated to be 5.0 at higher temperatures where only
CaSO4 is formed. A combined sinter/sulfation model,
based on the parameters evaluated for the independ-
ent processes, is compared to sulfation rates meas-
ured for the uncalcined solid when sintering is occur-
ring simultaneously.

The role of coal combustion as a significant global
source of nitrous oxide (N2O) emissions was reexam-
ined through on-line emission measurements from six
putverized-coal-fired utility boilers and from laboratory
and pilot-scale combustors. The full-scale utility boilers
yielded direct N2O emission levels of less than 5 ppm.
The sub-scale combustor test data were consistent
with full-scale data, and also showed N2O emission
levels not exceeding 5 ppm, although these levels in-
creased slightly when various combustion modifica-
tions to lower NO emissions were employed. These
on-line emission measurements are very different from
previously published data. The discrepancy is shown
to be due to a sampling artifact by which significant
quantities of N2O can be produced in sample contain-
ers which have been used in establishing the prevous-
ly employed N2O data base. Consequently, it was con-
cluded that N2O emissions bear no direct relationship
to NO emissions from these combustion sources, and
that the direct source of N2O is negligible. Other indi-
rect routes for the conversion of NO into N2O outside
the combustor and other combustion sources not ex-
amined by the study, however, cannot be ruled out.

Batch equilibrium and column miscible displacement
techniques were used to investigate the influence of
an organic cosolvent (methanol) on the sorption and
transport of three hydrophobic organic chemicals
(HOCs) - naphthalene, phenanthrene, and diuron her-
bicide - in a sandy surface soil (Eustis fine sand). Equi-
librium sorption constant (K) values calculated from
batch and column data exhibited an inverse log-linear
dependence on the volume fraction (fc) of methanol in
the mixed solvent. The slope of the log-linear plot was
approximately equal to the logarithm of the ratio of the
HOC solubilities in neat cosolvent and water. K values
obtained from breakthrough curves were comparable
to those estimated from equilibrium sorption isoth-
erms. Long-term exposure to methanol-water mixtures
had little effect on sorption and transport properties of
the soil, but column retardation factors were influ-
enced by the short-term solvent exposure history prior
to solute elulion.

The fluid passing through the pores of soils and geo-
logic materials is not just water with dissolved inorgan-
ic chemicals, but a complex mixture of organic and in-
organic molecules. Large organic molecules such as
humic and fulvic materials may impact the movement
of contaminants. If the large organic molecules are
mobile and they act like surfactant micelles, they can
facilitate the movement of hydrophobic organic con-
taminants. Enfield and Bengtsson performed a sensi-
tivity analysis evaluating the importance of several
processes that might impact the movement of hydro-
phobic organic chemicals. The sensitivity shown in the
analysis demonstrates the importance of a knowledge
of the mobility of the organic colloids and the ability of
the organic colloids to partition a contaminant and fa-
cilitate its movement as well as the amount of organic
colloid present. The analysis indicates that if the col-
loid is not mobile it will not have an impact on chemical
transport and also shows the importance of the
amount of mobile carbon assuming the partition coeffi-
cient was the same for all carbon (mobile and associ-
ated with the mineral fraction of the soil). Experimental
evidence of facilitated transport for hexachloroben-
zene due to the presence of a polysaccharide (blue
dextran) is also discussed.

For complex nonaqueous phase liquids (NAPLs), the
composition of the NAPL retained in the pore space of
geologic material weathers until the residual NAPL no
longer acts as a liquid and exists as discrete regions of
hydrocarbon (termed residual hydrocarbons) in asso-
ciation with the geologic media (water wet media), or
as thin film coatings on the media (NAPL wet media).
In the study, the residual hydrocarbons were found to
resist separation from the soil solids even when sub-
jected to shaking in batch reactors. In addition, the
magntude of solute sorption was significantly higher
for a low organic carbon soil contaminated with residu-
al hydrocarbons than for natural soil organic carbon.

The effectiveness and feasibility of bioremediated soil
venting of light hydrocarbons in the unsaturated zone
was investigated. Degradation mechanics were con-
sidered as a one dimensional balance of storage,
linear sorption, vertical advection, and Michaelis-
Menton kinetics. The resulting analytical solution was
tested successfully against field performance data of
an unsaturated clay soil bioreactor for a pollpellant
waste gas mixture of propane, n-butane, and isobu-
tane. A series of venting simulations was run to assess
the biodegradation of vapors above an aviation gaso-
line spill in sandy soil at Traverse City, Michigan, based
on field and microcosm estimates of the kinetic param-
eters. Acclimated, nutrient rich soil effectively and fea-
sibly reduced effluent vapor concentration from the
strong influent concentration associated with dis-
persed residual gasoline in the contaminated capillary
fringe. Aggregated residual contamination required a
stronger airflow for a longer duration while natural ki-
netics were too slow for feasible and effective treat-
ment by bioremediated soil venting at Traverse City.

A jar-rolling apparatus was constructed to prepare test
substrates using sediments spiked with laboratory
chemicals, the toxicity of which were assessed with
the Rhepoxynius abronius bioassay. Test sediments
were mixed by rolling them for several hours in one-
gallon glass jars. Mixing was considered adequate
based on the analytical results of sediment samples
that were collected at locations along the longitudinal
axis within each horizontally lying jar immediately after
rolling. However, because comparative standards did

The water quality of the upper Potomac Estuary near
Washington, D.C., has changed dramatically during
the past century. The channels that carried untreated
wastewaters from the city in the mid-1880s are gone.
The low dissolved oxygen levels, nuisance algal condi-
tions, and high coliform densities in the upper estuary
which occurred in the 1950s and 1960s are also gone.
The improvements in water quality are a result of a
massive wastewater management effort costing over
$1 billion during the past 20 years. The paper reviews
the major scientific and technical issues as they were
presented to the decision-makers and follows these
decisions as they were accepted, rejected, and/or
modified. The review also includes how good the pre-
dictions for wastewater management efforts were, and
how the uncertainty issues were addressed. Special
emphasis is placed on the unpredicted 1983 algal
bloom and its causes. The review also includes cost
and benefits analyses, societal conveniences, and
zero discharge implications. (Copyright (c) 1990 by

Under the Clean Air Act, the USEPA establishes ambi-
ent air quality standards to protect public welfare from
known or anticipated adverse effects from criteria air
pollutants. Although adversity is simply defined (i.e.,
opposed to one's interest; harmful), its determination
is fraught with difficulties. The definition depends on
one's viewpoint; society has established that some ef-
fects are more serious than others. There is a view that
ecological effects are adverse only if they can be ex-
pressed in economic terms. This leads to the conclu-
sion that mitigative actions need not be taken unless
the costs of the action are offset by sufficient benefits.
Adverse effects, however, should be viewed in a
broader societal content i.e., the total benefits from
ecological systems. (Copyright (c) 1990, ASA, CSSA,

Methods for describing the exposure patterns of for-
ests to atmospheric ozone concentrations are com-
pared with special emphasis on the situation at high al-
titudes, such as the Appalachian Mountains of the
eastern USA. Limitations to the use of ozone concen-
tration as mass per unit volume are discussed and a
correction for temperature and pressure changes is
derived. If identical ozone mass concentrations were
measured at two sites separated by 2000 m elevation,
the ozone flux at the lower site would exceed the flux
at the higher site by 4-8% due to the temperature and
pressure effects on both air volume and ozone deposi-
tion velocity. It is recommended that ozone exposures
be described in terms of Dux-corrected' mass concen-
trations or volumetric mixing ratios when ambient
ozone data from sites at different altitudes are to be
compared. (Copyright (c) 1990 Elsevier Science Pub-

Two northern bobwhite (Colinus virginianus) reproduc-
tion tests were conducted concurrently to evaluate
how the duration and time of initiation of methyl parath-
ion exposure affected dose-response relationships of
reproductive parameters. In the long-term exposure
test pairs of adult bobwhite were fed methyl parathion-
amended diets (0,7,10,14,20 or 28 ppm) for 25 weeks:
10 weeks prior to the onset of laying, 6 weeks as they
came into laying condition and 9 weeks during egg
laying. In the short-term exposure test, quail received
amended diets (0,10,14,20,28, or 40 ppm) for only
three weeks during the egg laying period, followed by a
three-week posttreatment period. Fourteen birds died
in the long-term test compared to two in the short-
term test Significant dose-related reductions in daily
food consumption, egg production and the number of
14-d-dd chicks were observed in both tests during the
treatment periods. No dose-related effects on fertility,
hatchability or chick weights were detected. In the
long-term test there were dose-related decreases in
adult body weight brain and serum cholinesterase ac-
tivity and female serum calcium concentrations. Cho-
linesterase and calcium were not measured in the
short-term test Eggshell weights were significantly de-
creased in both tests, but a dose-related decrease in
eggshell strength and thickness was detected only in
the short-term test

The effect of a short-term dietary methyl parathion ex-
posure on northern bobwhite (Colinus virginianus) egg
production and shell quality was investigated. Hens in
egg production were fed either a methyl parathion diet
(0,14,20,28 or 40 ppm) or a pair-fed diet (PF28 or PF40
received the same daily allotment of control feed on a
g/kg/d basis as the 28 or 40 ppm-treated hen with
whom she was paired) for 8 d. Daily food consumption
was significantly reduced in all treatment groups and
inversely related to chemical concentration. However,
actual chemical consumption was similar for all methyl
parathion-treated groups. Body weight, egg produc-
tion, egg weight and eggshell strength, thickness and
weight were reduced in the methyl parathion groups in
a dose-related manner. Similar responses were ob-
served in the pair-fed groups, indicating that effects
were associated with a pesticide-induced reduction in
food consumption. The dietary methyl parathion expo-
sure impacted bobwhite egg production within 3 to 4 d
and eggshell quality within 1 d of the onset of treat-
ment.

Existing statistical methodology has been adapted to
give additional insight into the data on pine-growth re-
duction in the Southeast as presented by Sheffield et
al. (1985). Specifically the generation of confidence in-
tervals for the percentage growth reduction is illustrat-
ed. The probability integral transformation and cumula-
tive sum techniques are employed as a meta-analytic
approach to testing the significance of the growth re-
duction. While these methods are suggested as a
means of obtaining a quantitative overview of these
particular data, the potential for wider application
exists. It is also shown how the observed pattern of re-
duction and most, if not all, of its magnitude can be ex-
plained by a simple conceptual model for hardwood
competition. Verification of the approach is, however,
not possible with the data as provided by Sheffield et
al. (Copyright (c) 1990 by the Society of American For-

Several government agencies are evaluating policy
options for addressing global climate change, these
include planning for anticipated effects and developing
mitigation options where feasible if climate does
change as predicted. For fisheries resources, policy
questions address effects on international, national,
and regional scales. Climate change variables expect-
ed to affect inland and offshore fisheries include tem-
perature rise, changes in the hydrologic cycle, alter-
ations in nutrient fluxes, and reduction and relocation
of spawning and nursery habitat. These variables will
affect resources at all levels of biological organization,
including the genetic, organism, population, and eco-
system levels. In this context changes in primary pro-
ductivity, species composition in the food-web, migra-
tion, invasions, synchrony in biological cycles, shifts in
utilization of niches, and problems of larvae entrain-
ment in estuaries have been identified. Maintaining
ecosystem robustness (i.e., high biodiversity) is an-
other component of the problem. Action requires es-
tablishing priorities for information needs, determining
appropriate temporal and spatial scales at which to
model effects, and accounting for interactive changes
in physical and biological cycles. A policy response
can be derived when these results are integrated with
social needs and human population constraints.

Escherichia coli, Pseudomonas fluorescens, and a
Pseudomonas sp. strain 133B containing the pSa plas-
mid were starved in well water for up to 523 days.
There were two patterns of apparent antibiotic resist-
ance loss observed. In Pseudomonas sp. strain 133B,
there was no apparent loss of antibiotic resistance
even after starvation for 340 days. In E. coli, by day 49
there was a ten-fold difference between the number of
cells that would grow on antibiotic- and nonantibiotic-
containing plates. However, over 76% of the cells that
apparently lost their antibiotic resistance were able to
express antibiotic resistance after first being resusci-
tated on non-selective media. By day 523, only 12% of
these cells were able to express their antibiotic resist-
ance after being resuscitated. After starvation for 49
days, cells that could not grow on antibiotic medium
even after resuscitation, showed a permanent loss of
chloramphenicol (Cm) resistance but retained resist-
ance to kanamycin (Km) and streptomycin (Sm).

A relatively clean raw surface water can be determined
that is amenable to disinfection as the only controlling
treatment process. The essential criteria and associat-
ed standards are: Fecal coliform 20 organisms/100
ml_ turbidity 1.0 NTU, color 15 ACU, and chlorine
demand 2 mg/L. These criteria were selected from a
study of a variety of data gathered from 34 raw source
waters used by utilities in full scale application of disin-
fection as the only treatment process. Selection of
water characteristics was based on the potential for
impact on disinfection effectiveness and magnitude of
fecal pollution tolerated. Watershed management is an
essential aspect of controlling water quality fluctua-
tions and in preventing progressive deterioration in the
raw water resource. Monitoring data should not only be
utilized to form a continual historical record that dem-
onstrates water quality suitability for minimal treatment
but also as an integral part of guidance in making day
to day changes in process control to avoid any chance
for microbial penetration into the public water supply.

There is a renewed interest in disinfection with chlorine
dioxide in the United States because of upcoming Fed-
eral regulations on disinfection by-products. Bench
studies and field applications of chlorine dioxide have
shown that it is an effective biocide that does not
produce halogenated by-products such as trihalo-
methanes. There are some health concerns with in-
gesting chlorine dioxide and its metabolites, chlorite
and chlorate, and concerns about tastes and odors.
These concerns may be alleviated by removing the
chlorine dioxide species with granular activated carbon
or reducing them to chloride before water distribution.

The permeation resistance of thin polyester films and
metallized, low-density polyethylene (LDPE) films was
evaluated to assess their feasibility for use in chemical
protective clothing applications. For a 0.002 cm poly-
ester film, permeation tests were conducted with ace-
tone, carbon disulfide, dichloromethane, and tetrahy-
drofuran. In all cases no permeation was detected for
a five hour duration at the sensitivity of the permeation
method. Concentrated sulfuric acid, however, severely
degraded the polyester film. Permeation tests were
also conducted with a series of 0.0033 and 0.0071 cm
LDPE, metallized-LDPE films, and their laminates to
study the contribution of the metal layer to the barrier
properties. Tests with dichloromethane were per-
formed on the films and laminates as is and also after
flexing. In all cases, the dichloromethane permeation
rates were lower through the metallized-LDPE films
than through the LDPE substrate alone when tested
without flexing. The permeation rates through the met-
allized-LDPE films following flexing, however, were
similar to those measured for the LDPE substrate.

Under the Superfund Innovative Technology Evalua-
tion (SITE) Program, the U.S. Environmental Protec-
tion Agency (U.S. EPA) is seeking to foster the further
development of technologies that have been success-
fully tested at bench-scale and are now ready for pilot-
scale testing, prior to field- or full-scale demonstration.
The goal is to ensure that permanent, cost-effective
technologies will be ready for field demonstration,
thereby increasing the number of viable alternatives
available for use in Superfund removal and remedial
actions. Under this program, the U.S. EPA can offer
technology developers financial assistance of up to
$150,000 per year, for up to two years. The program is
now initiating its fourth solicitation (E04) with two
projects form the E01 solicitation completed; five more
E01 projects are scheduled for completion by Septem-
ber 30, 1990; eight E02 projects are starting their
second year; and 16 projects were selected from the
third (EOS) solicitation. The fourth Emerging Technolo-
gy Program Solicitation is open to the receipt of new
proposals from July 6, 1990, through September 7,
1990. The purpose of the article is to provide the
reader with (1) an introduction to the Emerging Tech-
nology Program (ETP); (2) an understanding of how
the Program operates; (3) a summary of those technol-
ogies currently being tested and evaluated under the
Program; and (4) information on how to apply to the
Program.

place in April, 1988 at a site contaminated mainly with
polychlorinated biphenyls (PCBs). EPA tested the soil
before and after treatment and the EPA evaluation of
the process is based on results from the testing. A year
later, in April 1989, EPA tested again the treated soil
and results of that testing were compared to those of
the demonstration. Results of the EPA evaluation of
the IWT process, the Geo-Con performance, and treat-

The Superfund Innovative Technology Evaluation
(SITE) program was authorized as part of the 1986
amendments to the Superfund legislation. It repre-
sents a joint effort between the U.S. EPA's Office of
Research and Development and Office of Solid Waste
and Emergency Response. The program is designed
to assist and encourage the development of waste
treatment technologies that would contribute to more
solutions to our hazardous waste problems. Recently,
EPA, through the SITE program, issued a work assign-
ment to assess the 'state-of-the-art' of electrokineti-
caHy enhanced contaminant removal from soils. Prior
research efforts, both laborator and field, have demon-
strated the etecto-osmosis has the potential to be ef-
fective in facilitating the removal of certain types of
hazardous wastes from soils. Particularly encouraging
results have been achieved with inorganics in fine
grained soils where more traditional removal alterna-
tives are less effective. Although the results of various
studies suggest that electrokinetics is a promising
technology, further testing is needed at both the labo-
ratory and field levels to fully develop this technology
for site remediation. A conceptual test program is pre-
sented based on best available data which incorpo-
rates system design and operating parameters used in
previous applications of this technology in the use of
electrokinetics treatment as a remediation technique
at hazardous waste sites. (Copyright (c) 1990-Air &

Seasonal variations in the reductions of total coliform,
local coliform, fecal streptococci, and enterovirus den-
sities that occur during conventional aerobic sludge di-
gestion in cold climates were characterized. Also, the
potential to improve reductions in the densities of
these four groups of enteric microorgamsms in cold cli-
mates by simple modifications that increase process
temperature by reducing heat losses was demonstrat-
ed. To obtain this data, two 32 cu m aerobic digesters
located at a small municipal wastewater treatment
plant were operated continuously over a period of
twenty months. One digester was a conventional di-
gester white the other was designed to minimize heat
tosses, and thus, facilities autoneating. When the re-
sults obtained during 11 separate periods of steady-
state operation at mean mixed liquor temperatures
ranging from 8 to 40 C and at residence times of 10,
15, and 20 days were combined for analysis, it was evi-
dent that significant reductions in the densities of the
four groups of enteric microorganisms was dependent
both residence time and temperature. Using the Arr-
henius equation, it was possible to describe mathe-
matically the temperature dependence of the rate of
Iog10 reduction in density of each of these four groups
of enteric microorganisms. The four mathematical rela-
tionships developed provide a rational basis to deter-
mine residence times necessary to achieve desired
levels of indicator organism and enterovirus reductions
during aerobic sludge digestion at mixed liquor temps.

The effects of continuous and amplitude-modulated
radiofrequency electromagnetic waves on calcium
efflux from 45 Ca preloaded frog hearts were exam-
ined. Frog hearts, electrically stimulated at their natural
beating frequency, were exposed for 30 min to 240
MHz radiowaves in a Crawford irradiation cell. Expo-
sures at incident power levels of 0.5, 0.8,1.0,1.2, 5.0
and 10.0 Watts (corresponding to calculated specific
absorption rates (SAR) of 0.15, 0.24, 0.30, 0.36, 1.50,
and 3.00 mW/kg) were tested either in the continuous
wave mode or using sinusoidal amplitude modulation
at 0.5 Hz, the average beating frequency of the frog
hearts, or at 16 Hz. Continuous at 0.5 Hz amplitude-
modulated waves did not affect calcium efflux from the
hearts. However, 16 Hz amplitude-modulated electro-
magnetic radiation resulted in statistically significant
increases in calcium efflux. The effect was most signif-
icant at the 1 W incident power level (17.9%, p<0.01)
but was also observed at 0.5 W(21.0%, p<0.05).
Therefore, it appears that frog hearts are affected by
electromagnetic radiation at particular power levels
and 16 Hz modulation frequency, a bioelectromagnetic
interaction displaying power and frequency windows
comparable to those reported by other investigators in
calcium efflux studies on neural tissue.

Adult female, Fischer-344 rats were exposed to 275
mg/kg of Ws(2-chtoroethyl)phosphate (TRCP) by
gavage. TRCP produced consistent signs of convul-
sive activity within 60-90 minutes after dosing and ex-
tensive toss of CA1 hippocampal pyramidal cells when
examined 7 days after dosing. At the light microscopic
level, toxic effects of TRCP on pyramidal cells in the
CA3, and CA4 and granule cells in the dentate gyrus
were less severe than on the CA1 cells. The seizure-
related and neurohistological effects of TRCP were
significantly attenuated by pretreatment with atropine
or chkxdizepoxkJe, suggesting that the hippocampal
damage was related to the seizures produced by
TRCP. In a second experiment designed to assess the
potential health risk associated with TRCP, exposed
rats were mildly impaired in the acquisition of a refer-
ence memory task in a water maze. However, TRCP-
exposed rats were consistently impaired in performing
a repeated acquisition task in the water maze. These
data underscore the potential health risk associated
with exposure to TRCP and support the conclusion
that the hippocampus is intimately involved in spatial
memory in rats. (Copyright (c) 1990 Academic Press

Recognition that most human exposures to environ-
mental chemicals occur as complex mixtures has stim-
ulated research and the development of new methods
to assess exposure, dosimetry, and genotoxic effects.
New genetic and molecular methods are being applied
to each aspect of research to develop new methods
for the assessment of cancer risk from human expo-
sure to complex mixtures. Short-term genetic bioassay
methods utilizing new engineered bacterial strains are
being used to assess total human exposure to muta-
gens in the environment New DNA adduct methods
are being used in exposure-dpsimetry studies of com-
plex mixtures in humans and in experimental systems.
Finally, new advances in sequencing the genetic muta-
tions induced by environmental mutagens wjll improve
our understanding of the relationship between DNA
adducts, DNA damage and repair, mutation induction,
and tumor initiation.

A CASE SAR analysis was performed on a selected
database of PAH's to investigate the possible use of
the CASE method as an aid for preliminary assess-
ment of carcinogenic potential of untested environ-
mental PAH's. A data set consisting of 78 PAH's and
their experimental carcinogenicities was used to 'train'
the CASE fragment These fragments predicted the
activities of 94% of the training' set correctly. Using
these fragments, the potential activities of a database
of 106, mostly untested PAH's were predicted and
compared to 'expert judgement' predictions in order to
evaluate the extent of concordance between these
two methods. Initial poor agreement (64%) was attrib-
uted to inadequate CASE knowledge of 2- and 3-ring
PAH subclasses; when these subclasses were ex-
cluded, the concordance improved to 90%. The pre-
diction accuracy of 75%, despite the structural diversi-
ty of the data set, provided independent evidence of
the utility of the present CASE results. A close exami-
nation of the CASE incorrect predictions was conduct-
ed to delineate inadequacies of these CASE results in
order to provide cautionary guidance for future applica-
tion of the method. Finally, the present results were
compared to the results of a previous CASE analysis
based on a more limited PAH data set, and were found
to be of greater general utility.

The effects of a radiomimetic chemical, bleomycin
(BLM), on meiotic chromosomes was evaluated in
mice. Chromosome aberrations were analyzed at mei-
otic metaphase I, and damage to the synaptonemal
complex was analyzed in meiotic prophase cells. In the
metaphase aberration studies, an ip. injection of 80
mg/kg BLM, timed to precede or coincide with ultimate
S-phase, led to a significant increase in structural
damage (p<0.01) in cells reaching metaphase I 12 d
after treatment. However, no increases in clastogenic
effects were observed at metaphase I after treatment
of cells during various stages of prophase. SC analy-
ses in pachytene cells following an ip. or it. injection at
S-phase revealed various forms of synaptic errors and
structural anomalies, including qualitative changes
similar to those observed following irradiation. Ip.
doses ranging from 25-100 mg/kg, and it. doses as
low as 0.5 mg/kg, caused roughly sixfold increases
over control levels in the number of damaged cells. It
was concluded that BLM is clastogenic for meiotic
chromosomes; however, it does not reveal the strong
S-independedt clastogenic activity at meiosis that is
characteristic of its activity at mitosis.

The present study was designed to determine and
compare the clastogenicity of amsacrine and camp-
tothecin in vivo in mouse bone marrow and peripheral
blood lymphocytes and in vitro in mouse lymphoma
L5178Y cells. It was expected that amsacrine, which
interferes with topoisomerase II to induce double-
strand DNA breaks, and camptothecin, which inter-
feres with topoisomerase I to induce single-strand
DNA breaks, would induce different types of chromo-
somal aberrations. However, both drugs produced
quantitatively and qualitatively similar numbers and
types of aberrations under similar experimental condi-
tions. In mouse bone marrow, both drugs (3 mg/kg) in-
duced about 30% damaged cells, with an average of
0.4 chromatid breaks per cell. Cell cycle specificity was
indicated by the absence of chromosomal aberrations
when exposure to the drugs occurred during GO in
vivo. In vitro, amsacrine, and camptothecin induced
161 and 20 mutants/10 (to the sixth power) survivors/
nM. respectively; they induced 6 and 2 aberrant cells/
nM, respectively. In contrast to the in vivo results, the
drugs induced high levels of both chromatid- and chro-
mosome-type aberrations in vitro.

The L5178Y/TK+/- mouse lymphoma assay is uti-
lized to quantitate the induction of thymidine kinase
(TK)-deficient mutants. TK-heterozygous cells are
treated with the test compound, newly induced mu-
tants are allowed to express, and mutants are selected
with trifluorothymidine (TFT). Mutant colonies detected
in the assay can be classified by colony size as large
(> than approximately 0.6 mm) and small (< than ap-
proximately 0.6 mm). An extensive analysis of these
two classes of mutants has led to the hypothesis that
the two types of mutants result from different degrees
of genetic damage and that the assay can be used to
detect and discriminate between chemicals acting as
point mutagens (inducing significant numbers of large
colonies) and/or clastogens (inducing significant num-
bers of small colonies). This raises the question as to
how the small-colony TK mutant frequency would be
related to the gross aberration frequency obtained by
standard microscopic technique. Preliminary studies
with a very small number of chemicals indicated that
there might be a simple mathematical comparison be-
tween the two endpoints.

Among the nitro-substituted polycyclic aromatic hydro-
carbons identified in environmental samples and
known to be genotoxic, 1-nitropyrene is one of the
most abundant. The biotransformation of 1-
nitro((14)C)pyrene by human, rat, and mouse intestinal
microflora and the mutagenicity of the isolated meta-
bolites by direct analysis of the HPLC fractions with a
microsuspension mutation assay were investigated. 1-
nitro((14)C)pyrene was metabolized by human, rat and
mouse intestinal microflora to the following reductive
metabolites; 1-aminopyrene, Nacetylaminopyrene, N-
formyl-1-aminopyrene and two unknown metabolites
identified as A and B. The predominant metabolite of
1 -nitro((14)C)pyrene produced by human, rat or mouse
intestinal microflora following a 12 h incubation was 1-
aminopyrene which accounted for 79 to 93% of the
total (14)C respectively. Only minor amounts of N-
formyl-1-aminopyrene (1%), N-acetylaminopyrene (3 -
4%) were produced. The similarity in the distribution of
the reductive metabolites suggests that a similar
mechanism exists in the biotransformation of 1-nitro-
pyrene by intestinal microflora of different mammalian
species.

Recent theories of hippocampal function focus on its
role in the formation of associations in the temporal
domain. A reversal learning paradigm based on lever-
press automaintenance was developed to vary the CS-
UCS relationship along two independent dimensions,
one temporal and one not: CS+-UCS delay and the
probability of reinforcement (P(RFT)) following the
CS+. Eight male hooded Long-Evans rats were
trained to reverse the automaintained discriminations
repeatedly, until stable reversal performance was
achieved. The neurotoxicant trimethyltin (TMT) was
used to induce lesions in the CNS, including the CA3-4
region of Ammon's Horn in dorsal hippocampus. Fol-
lowing iv injection of 7 mg/kg TMT to half the rats, re-
versal performance was assessed under varying con-
ditions of delay and P(RFT). After recovery from the
acute effects of TMT (1-2 weeks), treated rats re-
versed normally when no delay separated the CS+
and UCS; with delays of 2 to 4 sec, they reversedless
completely within a session than did controls. The
degree of behavioral impairment correlated significant-
ly with hippocampal damage only at nonzero CS + -
UCS delays.

Male Sprague-Dawley rats were treated with either
dichloroacetic acid (DCA) or trichloroacetic acid (TCA)
in the drinking water at levels of 0, 50, 500 and 5000
ppm for a period of 90 days to determine the toxicities
associated with subchronic exposure. All animals were
sacrificed and examined for gross and histopathologic
lesions, serochemical changes, immune dysfunction,
hepatic peroxisomal and mixed function oxidase
enzyme induction and organ-body weight changes.
Animals treated with DCa had decreased body weight
gains (500 and 5000 ppm) and decreased total serum
protein (all doses). Rats given either TCA (5000 ppm)
or DCA (500 or 5000 ppm) had increased liver and
kidney organ to body weight ratios. Rats offered DCA
had significantly elevated alkaline phosphatase (500
and 5000 ppm) and alanine-amino transferase (5000
ppm). No consistent immunotoxicity was observed in
animals exposed to either compound. Rats treated
with 5000 ppm TCA or DCA had significantly increased
hepatic peroxisomal beta-oxidation activity. (Copyright

The processes of aging result in many physiological
changes which can lead to alterations in both pharma-
cokinetic and pharmacodynamic properties. Such
changes can result in altered sensitivity to chemicals,
whether drugs or environmental agents, in the elderly.
It is extremely difficult, however, to generalize about
the nature of such changes. Part of this may reflect
disagreement, or at least, confusion in the literature
over what the term 'age' means. It is not uncommon
for a study to discuss age-related changes and, in fact,
be comparing neonatal to pubescent or young adult
animals. Therefore, it is clear that 'age' should always
be clearly defined. When interest is in post-maturation-
al organisms, and, at the very least, those at the mean
life span of the population. The requirement has been
stated before, but not always adhered to. Studies com-
paring only very young and terminally senescent ani-
mals may not provide fair representation of the effects
occuring over the life-span of the species in question.
While no broad generalization can be made about
pharmacokinetic and/or pharmacodynamic changes,
it is probably fair to state that such changes will often

Linear models of risk assessment may be appropriate
for chemical that are initiators of carcinogenesis while
threshold model of risk assessment have been pro-
posed for promoters. The proper risk assessment
model for the regulation of promoters of carcinogene-
sis remains an active area of research and controver-
sy. Cancer is a multistage process (e.g. initiation, pro-
motion and progression). These three stages of the
pncogenic process have different biological character-
istics. Studies to determine which chemicals effects
which stages and to what degree are needed for risk
assessment. The in-vivo biochemical system de-
scribed in the report can be performed in a species
specific and organ specific manner. In the report 1,4-
dioxane is given to rats at doses of 168, 840, 2550, or
4200 mg/kg. DNA damage occurred at 2550 and 4200
mg/kg. This is the first description of genotoxicity of
1,4-dioxane in-vivo. Hepatic ornithine decarboxylase
activity was also induced by 1,4-dtoxane. This 1,4-diox-
ane appears to be a weak genotoxics carcinogen and
a strong nongenotoxic carcinogen.

Ornithine decarboxylase (ODC), the rate-limiting
enzyme in polyamine synthesis, was significantly in-
duced in female rat liver following oral administration
of the pesticide, mirex. After dual oral exposure (120
mg/kg; 21 and 4 hrs. prior to sacrifice) induction of
ODC activity in rat liver cytosol was 70-fold as com-
pared to controls. A single oral dose of mirex (180 mg/
kg) induced hepatic ODC activity 55-fold over controls.
The time-course study indicated that maximal induc-
tion of ODC activity after a single oral dose of mirex
was at 36 hours post-dosing. Though the exact mech-
anisms is still unclear, it appears that sex could be a
pre-disposing factor in the induction of ODC activity in
rat liver. Mirex is an unusually strong and long lasting
inducer of rat hepatic ODC activity. (Copyright (c) 1990

The biochemical and morphological neurotoxic effects
of postnatal acetylcholinesterase (AChE) inhibition
were examined in rat pups dosed with parathion, at
time points critical to hippocampal neurogenesis and
synaptogenesis (i.e., D5-20). Hippocampal cytopatho-
logy as assessed by light and electron microscopy,
consisted of cellular disruption and necrosis in the DG,
CA4, and CA3a regions. Synaptic disruption in the DG
molecular layer was suggested by histochemical prep-
aration using both the Timm's and AChE stains. In par-
athion-treated D12 pups, hippocampal AChE was de-
pressed 70% and QNB binding depressed by 36%.
The above results indicated that definite neurotoxic
consequences are associated with persistent AChE
depression in the neonatal rat.

Sudden death frequently occurs from coronary artery
disease. It almost always results from cardiac arrhyth-
mias and is often the first and only clinically recogniz-
able manifestation of the disease process (1). Be-
cause of the relations among cardiac arrhythmias,
sudden death, and coronary artery disease, as well as
the high prevalence of coronary artery disease in the
United States today, it is important to answer the ques-
tion of whether or not exposure to carbon monoxide
causes arrhythmias (2-10). Few carefully controlled
double-blind studies exist with adequate control moni-
toring periods to assess spontaneous variability of ar-
rhythmias in the control period. The purpose of double-
blind study was to ascertain whether carbon monoxide
exposure leading to elevated venous carboxyhemog-
lobin concentrations has an arrhythmogenic effect in
patients with coronary artery disease. (Copyright (c)

Thirty-six male C57B1/6 mice were whole-body x-irra-
diated with 3 Gy to generate lymphocytes with dicen-
tric chromosomes to study the persistence of these
lymphocytes in the spleen and peripheral blood to esti-
mate the lifespan of mature B- and T-cells. Blood and
spleen were removed from groups of four mice imme-
diately after radiation exposure and on days 1,3,7,14,
28, 56, and 12, thereafter. The initial frequencies of di-
centric chromosomes with accompanying fragments
observed in splenic T-cells (0.44), splenic B-cells
(0.43), and peripheral blood lymphocyte cultures (0.48)
initiated on day 0 were not significantly different. For
both splenic and peripheral blood-T-lymphocytes, the
frequency of cells containing dicentric chromosomes
declined in an exponential manner following irradia-
tion, with a 50% reduction in frequency occurring 14
days after exposure. In contrast, the frequency of B-
cells containing dicentric chromosomes remained
stable through day 7 but then declined precipitously
between day 7 and 14 and remained relatively stable,
although slightly above baseline, through day 112
post-exposure.

Hexachlorobenzene (HCB) exposure has been shown
to induce hyperparathyroidism and osteosclerosis in
rats. Experiments were undertaken to investigate the
effects of HCB on femur morphometry as well as
breaking strength. Fischer 344 rats were dosed 5
days/wkfor 15 wks with 0,0.1,1,10 or 25 mg HCB/kg
body weight. Hyperparathyroidism was produced in the
two higher dose groups as reported previously (An-
drews et al., 1988). Femur weight was significantly in-
creased in the rats receiving 0.1,1 and 25 mg HCB/kg
body weight wheras density was increased significant-
ly at 1, 10 and 25 mg HCB/kg dose levels. Bone
strength was also significantly increased at the three
higher dose levels. Bone flexibility was significantly in-
creased at the 0.1 mg HCB dose level. Cross sectional
area of the midpoint of the femur was significantly in-
creased at the 1 mg/kg HCB dose level. Cortical area,
as well as the proportion of the total area of the bone
which the cortex occupied, were significantly in-
creased at the three higher dose levels. Medullary
cavity area was significantly increased at the 0.1 mg/
kg dose level but significantly decreased at the two
higher dose levels of HCB.

A study was conducted to relate the properties of En-
terobacter, Pseudomonas, Bacillus, Achromobacter,
Flavobacterium, and Arthrobacter strains to their
transport with water moving through soil. The bacteria
differed markedly in their extent of transport; their hy-
drophobicity, as measured by adherence to n-octane
and by hydrophobic-interaction chromatography; and
their net surface electrostatic charge, as determined
by electrostatic interaction chromatography and by
measurements of the zeta potential. Transport of the
19 strains through Kendaia loam or their retention by
the soil was not correlated with hydrophobicities or net
surface charges of the cells or the presence of cap-
sules. Among 10 strains tested, the presence of flagel-
la was also not correlated with transport. Retention
was statistically related to cell size, with bacteria short-
er than 1.0 micro m usually showing higher percent-
ages of cells being transported through the soil. It is
suggested that more than one characteristic of bac-
terial cells determines whether the organisms are
transported through soil with moving water. (Copyright

Laboratory tests were conducted to evaluate whether
denitrification would be a suitable alternative for bior-
estoration of an aquifer contaminated with JP-4 jet
fuel. Microcosms were prepared from uncontaminated
and contaminated aquifer material, amended with ni-
trate, nutrients, and aromatic hydrocarbons, and incu-
bated under a nitrogen atmosphere at 12 C. With un-
contaminated core material, there was no observable
lag period prior to removal of toluene whereas 30 days
was required before biodegradation commenced for
xylenes, ethylbenzene, and 1,2,4-trimethylbenzene.
An identical test with contaminated aquifer material ex-
hibited not only much longer lag periods but decreased
rates of biodegradation; benzene, ethylbenzene, and
o-xylene were not significantly degraded within the 6-
month time period even though active denitrification
occurred at this time. First-order biodegradation rate
constants ranged from 0.016 to 0.38/day for unconta-
minated core material and from 0.022 to 0.067/day for
contaminated core material. Tests with individual com-
pounds in uncontaminated core indicated that ben-
zene and m-xylene inhibited the basal rate of denitrifi-
cation. These data demonstrate that several aromatic
compounds are degraded under denitrifying condi-
tions, but rates of biodegradation may be lower in ma-
terial contaminated with JP-4 jet fuel. (Copyright (c)

The Regional Oxidant Model (ROM) determines hourly
concentrations and fates of ozone and 34 other chemi-
cal species over a scale of 1000 km x 1000 km for
ozone 'episodes' of up to one month's duration. The
model structure, based on phenomenological con-
cepts, consists of 3 112 layers. The surfaces separat-
ing the layers respond to variations in space and time
in the meteorological phenomena simulated in each
layer. The model simulates many physical and chemi-
cal processes that affect the motion and distribution of
chemical concentrations; among these are: horizontal
transport, photochemistry, nighttime wind shear and
nocturnal jet; cumulus cloud effects and mesoscale
vertical motion; terrain and mesoscale eddy effects;
subgrid scale chemistry processes, natural sources of
hydrocarbons, NOx and stratospheric ozone; and dry
deposition. The ROM is a complex model that requires
users to have expertise in photochemical grid model-
ing. Meteorologists, engineers, and computer scien-
tists familiar with this type of modeling will find the
User's Guide relevant and helpful for running the
ROM.

Under the assumption that a malignant tumor devel-
ops through a sequence of steps (normal cells-> initi-
ated cells/foci-> nodules-> tumors) two classes of
mathematical models of carcinogenesis that have a
potential to be used for cancer dose-response model-
ing are discussed. The two classes of models consid-
ered are (1) a general version of the two-stage model
by Moolgavkar and colleagues, henceforth called the
MVK model, and (2) a clone process model derived
from Tucker. These two classes of models incorporate
essentially the same biological information but in dif-
ferent ways and offer a conceptual contrast between
the two differing approaches. The objectives of the
paper are to (1) highlight issues and problems that
arise in using biologically based dose-response
models to predict cancer risk and (2) discuss how pa-
rameters in the models could be estimated using auxil-
iary information.

In 1986, the U.S. Environmental Protection Agency
(EPA) published a series of guidelines for carrying out
human health risk assessments. As part of the ongoing
effort to develop guidance in areas not addressed by
the 1986 guidelines, EPA's Risk Assessment Forum
sponsored a series of meetings to consider issues rel-
evant to developing the Agency's first Agency-wide
guidelines for ecological risk assessment. The report
summarizes the discussion and conclusions of seven
information-gathering meetings held in the spring of
1990. Invited speakers and EPA staff addressed the
scope and content of future ecological guidelines, the
nature and diversity of ecological assessments, ap-
proaches to characterizing and quantifying uncertainty
in ecological hazard and exposure assessments, and
the potential use of population modeling for character-
izing ecological risk. Relying in part upon the results of
these discussions, EPA has embarked on a multiyear
effort to develop ecological risk assessment guidelines
that will foster consistency in the Agency's approach

A new, trajectory-type, air quality simulation model
called Ozone Isopleth Plotting Package (Research
Version) (OZIPR) has been developed. OZIPR is
based on previous versions of EPA's Ozone Isopleth
Plotting Program (OZIPP) Model, but contains im-
proved and expanded capabilities that make the model
useful for research purposes. OZIPR serves the dual
purpose of providing: (1) a simple trajectory model ca-
pable of using complex chemical mechanisms, emis-
sions, and various meteorological parameters, and (2)
procedures through which the Empirical Kinetics Mod-
eling Approach (EKMA) can be implemented to calcu-
late emission reductions for compliance with the Na-
tional Ambient Air Quality Standard for ozone. While
these capabilities were included in earlier versions of
OZIPP, the new OZIPR contains major improvements
that expand the program's capability to input utilize,
and output a much larger range of information. The
Project Report serves as a user's manual for OZIPR. It
contains a description of the model, along with input
and output requirements and options. The input and
output files for nine examples are also included.

The paper gives results of a fundamental evaluation of
an electronic air cleaner (EAC). The ozone generation
rate and particle-size-dependent (0.01-10 microme-
ters) filtration efficiency of an in-duct residential EAC
were measured. Filtration efficiencies were typically
70-90%, showing decreasing efficiency with increas-
ing flowrate. Ozone generation rates were about 3 mi-
crograms/s. Scans of the aerosol concentration on
the downwind face of the EAC were used to locate,
then eliminate, areas of aerosol sneakage. Sneakage
was detected along the top and bottom of the EAC
face, apparently due to incomplete aerosol charging
for aerosol passing near the ends of the ionizing wires.
Areas away from the top and bottom had near-zero
aerosol penetration. Based on these results, the inlet
to the EAC was masked to eliminate airflow through
the sneakage areas. The resultant efficiency of the
masked EAC was nearly 100% for particles larger than
0.1 micrometer diameter; however, the filtration effi-
ciency for particles smaller than 0.1 micrometer was
not significantly affected by masking.

The paper discusses a simplified model for soil-gas
transport through soil surrounding the substructure of
a house. The model provides the ability to answer, in
semi-quantitative terms, such fundamental questions
as: (1) What role does diffusion play in transporting
radon to the house/soil interface, where pressure-
driven flow tends to dominate the process of entry into
the house. (2) Do active subslab depressurization miti-
gation systems significantly increase the rate of emis-
sion of radon into the ambient air. (3) At what flow rate
through the subslab depressurization system does di-
lution of the radon in the soil gas contribute significant-
ly to the performance of the mitigation system. Simpli-
fying assumptions about the distribution of entry routes
and driving forces are used to relate indoor air radon
levels to soil characteristics and to dynamics within the
house. Preliminary validation of the model predictions
consists of demonstrating reasonable values for
indoor radon concentrations. While it is quite possible
to formulate a fairly rigorous mathematical model to
describe radon transport through soil, such a model
would require rather complex numerical solutions that
would be time consuming and expensive to evaluate.
Numerical solutions are also cumbersome for evaluat-
ing both the relative importance of the individual mech-
anisms and the appropriateness of alternative bound-

The paper discusses the use of EPA's bench-scale
pilot plant to evaluate catalysts used in the ammonia
(NH3)-based technology and process for selective
catalytic reduction (SCR) of nitrogen oxides. A key ob-
jective was to establish the performance of SCR cata-
lysts on U.S. fuels and combustion sources. A rudi-
mentary catalyst produced inhouse and two commer-
cial catalysts were evaluated. The temperature ranged
from 327 to 440 C. The space velocity ranged from
7650 to 36,500 hr to the -1 power. The combustion gas
was doped with nitric oxide (NO) and NH3, and the
NH3/NO ratio ranged from about 0.6 to 2.2. Sulfur di-
oxide (SO2) was added to the combustion gas in some
runs to investigate its effect on NO conversion over
one commercial catalyst. The formation of nitrous
oxide (N20) on the same catalyst at 400 C was also in-
vestigated. The evaluation indicated that, for the in-
house catalyst, the space velocity has a significant
effect on NO conversion. For the two commercial cata-
lysts, the NO conversion was 90% and higher when
the NH3/NO ratio was near or above unity, and the NO
conversion was approximately proportional to the NH3
concentration at the inlet of the reactor when the ratio
was less than unity. Flue gas SO2 was found to be poi-
sonous to one commercial catalyst. Furthermore, the
amount of N2O formed over the same commercial
catalysts was negligible.

Approximately 325 million cu m of sediment are
dredged annually for navigation purposes in the United
States. Of this, 46 million cu m are disposed of annual-
ly in the ocean. Decisions regarding the ocean dispos-
al of dredged material result, in large part, from bioas-
sessment-based estimates of contaminant exposure
and ecological impacts. Predictions of impacts for an
individual dredging project are estimated from labora-
tory determinations of the magnitude, bioavailability,
bioaccumulation, and hazards (toxicity) of dredged
material contaminants. Disposal site management of
individual and multiple dredging projects requires mon-
itoring for contaminant transport, availability and accu-
mulation in biota, and the hazards to ecologically and
commercially important populations. Because of their
importance, suites of bioassessment methods repre-
senting several levels of biological organization have
been proposed for predicting and assessing the haz-
ards resulting from the ocean disposal of dredged ma-
terial.

Once treated drinking water enters the distribution
system, substantial microbial, chemical, and physical
changes can occur. Examples of such changes can in-
clude loss of disinfectant residual, increases in disin-
fection byproducts (DBP), growth of microbial diversity
and population or an increase in heavy metal concen-
tration. These water quality changes often result in
aesthetic problems such as turbid water, red and/or
black water or tastes and odors. Such conditions do
not necessarily pose a threat to human health. Howev-
er, several water quality changes in distribution sys-
tems could violate Maximum Contaminant Levels
(MCLs) proposed by the Safe Drinking Water Act
Amendments and pose a threat to human health. As-
bestos fibers can be released into drinking water from
deteriorated asbestos-cement water mains (1). Treat-
ed waters may also have mutagenic potential from in-
creases in polycyclic aromatic hydrocarbons because
of the leaching of asphalt-lined pipes (2). Lead, trihalo-
methanes (THMs), other DBPs, or coliforms may
exceed the regulations at the tap although the water
leaving the treatment plant was in compliance.

The current monitoring procedures seem to select a
geographically representative sample, with an almost
complete disregard of the underlying water distribution
network. However, the quality of water changes as it
travels from the treatment plant to the consumer.
Thus, the purpose of the paper is to distinguish be-
tween aspects of macrolocation and microlocation of
sampling stations for not only compliance purposes
but to more accurately characterize water quality. Ma-
crolocation determines a general geographic area and
microlocation determines the specific house or tap.

The paper presents information on the state-of-the-art
of metals recovery technologies to assist in identifying
waste-management options dealing with recovery for
metal-bearing sludges and wastewaters that may be
regulated under RCRA and the Clean Water Act.
Waste treatment technologies (e.g., chemical precipi-
tation) that could eventually result in recovery of spe-
cific metals are also included in the paper. Metals re-
covery technologies addressed in the paper include
the following: chemical precipitation, electrolytic re-
covery, high-temperature metals recovery (HTMR),
membrane separation, leaching, ion exchange, and
evaporation. For each of these technologies, the fol-
lowing parameters are summarized: (1) design specifi-
cations of applicable processes, (2) waste characteris-

processes and corrosion rates. They provide a rela-
tively simple screening procedure for determining pos-
sibly favorable corrosion control water treatment strat-
egies. They cannot, however, be used as a substitute
for tap water monitoring. The better the pipe loop
mimics the conditions it is intended to model, the more

The recent emphasis on developing information on
achieving pollution prevention has resulted in in-
creased research activity by the Environmental Protec-
tion Agency (EPA) in the area of clean product devel-
opment. Currently the EPA's Pollution Prevention Re-
search Branch (PPRB) has six funded research
projects under the Clean Products Research Program.
These projects include (1) compilation of background
information, (2) profiling case studies of industries im-
plementing changes, (3) identification of safe substi-
tutes for toxic products, (4) life-cycle analysis method-
ology development, (5) development of guidance for
industry to use in self-evaluations of product and proc-
ess design, and (6) development of a method for
measuring pollution prevention. A brief description with
the status of each project is included in the paper. The
paper should be of interest to other researchers, in-

The Gamma distribution function can be useful for fit-
ting rainfall data. An integral part of the assessment of
storm loads on water quality is the statistical evalua-
tion of rainfall records. Hourly rainfall records of many
years duration are cumbersome and difficult to ana-
lyze. The Gamma distribution can be a tool to examine
variables of interest (volume, duration, intensity, and
time between storms) which are of importance in de-
termining seasonal trends and selecting control alter-
natives for storm related runoff.

Concern over the bioavailability of toxic organics that
can occur in municipal sludges threatens routine land
application of sludge. Available data, however, show
that concentrations of priority organics in normal
sludges are low. Sludges applied at agronomic rates
yield chemical concentrations in soil-sludge mixtures
50 to 100 fold lower. Plant uptake at these pollutant
concentrations (and at much higher concentrations) is
minimal. Chemicals are either (1) accumulated at ex-
tremely low levels (PCBs), (2) possibly accumulated,
but then rapidly metabolized within plants to extremely
low levels (DEHP), or (3) likely degraded so rapidly in
soil that only minor contamination occurs (PCP and

In response to the requirements of the Clean Water
Act, EPA is developing comprehensive regulations for
the use and disposal of sewage sludge, and published
proposed regulations in the Federal Register on Feb-
ruary 6. 1989. A portion of these regulations covers
disposal and use of sludge on land. The requirements
for pathogen and vector attraction reduction in the
18 Vol. 91, No. 3
sludge to be disposed to the land are presented, and
their technical bases are described. The proposed reg-
ulation is similar in approach to the current regulation
but corrects its deficiencies. Instead of requiring use of
specifically described processes that individually must
reduce pathogen densities and vector attraction to the
desired level, the proposed regulation instead sets
performance goals. For example, Allowable maximum
microbial densities (usually fecal indicator densities) in
the final sludge product have been identified instead of
describing process conditions to achieve these densi-
ties. For vector attraction reduction, performance
goals could be set, but they are not independent of
process type. The presentation provides scientific evi-
dence supporting the approach taken. Publication of
the regulation after consideration of public comment is
expected in January 1992.

Interest in slow sand filtration has increased dramati-
cally in the United States in the past ten years. Re-
search conducted to evaluate removal of Giardia cysts
and bacteria, showed that stow sand filtration is very
effective in removal of these contaminants. Slow sand
filters are much simpler and easier to operate than
plants that employ coagulation. Thus they are very well
suited for treatment of previously unfiltered surface
waters and would be well suited for small utilities serv-
ing from 25 to 3000 persons. The U.S. EPA estimates
that about 1000 slow sand filters may be built as a
result of proposed EPA regulations on surface water
treatment.

private sector and EPA. The purpose of the program is
to provide an opportunity for developers to demon-
strate the performance of their technologies on actual
hazardous waste materials, and provide reliable and
accurate information for future cleanup activities at Su-
perfund sites. Currently there are 38 active projects in
the Demonstration Program. Eight of these projects in-
volve solidification/stabilization, nine concentrate on
thermal processes, five are biological processes, and
the remaining 16 include separation techniques,
chemical treatment, and in-place vitrification. The

evaluate innovative measurement and monitoring
techniques and pursue an active technology transfer
program. Within the SITE Program, the Demonstration
Program and the Emerging Technology Program are
responsible for alternative technology development.
The SITE Demonstration Program has as its major
thrust the documentation of reliable performance and
cost information for innovative alternative technol-
ogies. The demonstration projects identify limitations
of the technology, the need for pre- or post-treatment
of wastes, applicable wastes and waste media, poten-

Several Federal regulations have been promulgated
and many more are expected for limiting the concen-
trations of contaminants in drinking water. As these
regulations are developed, Best Available Technology
(BAT) has to be stipulated for meeting these regula-
tions. Various treatment technologies have proven ef-
fective in controlling many drinking water contami-
nants of concern. For instance, one of the most prom-
ising methods for halogenated by-product control in-
cludes removal of precursors before disinfection. Re-
search studies in Florida indicate that membranes are
effective in removing halogenated by-product precur-
sors from certain waters. There are also other regula-
tory concerns where membranes can provide ade-
quate treatment. Membranes can be used for remov-
ing inorganics and radionuclides. Also, with appropri-
ate pilot-scale and field scale data, membranes could
possibly be considered BAT for meeting the Surface
Water Treatment Rule requirements.

Estimations of human risk are generally based on
animal studies, and thus require a species-to-species
extrapolation. Such data are usually obtained at expo-
sure levels much higher than those ordinarily encoun-
tered by humans; consequently, estimates of low-dose
risk require a consideration of how the animal dose-re-
sponse can be extrapolated to lower exposures. Infor-
mation on mechanisms and rates of DNA repair and on
similarities and differences among different cell types
and species is important in the development of biologi-
cally based extrapolation models for quantitative risk
assessment. Such information serves to guide or to
provide insight into predicted shapes of dose-re-
sponse curves at low exposures and how to extrapo-
late risk across species. The paper will present a con-
ceptual outline for considering how information on
DNA damage and repair mechanism may be applica-
ble to the assessment of health risks, particularly
those posed by exposure to carcinogens and muta-
gens.

The estimation of risk for health effects due to chemi-
cal exposure is important to the development of stand-
ards for regulating the manufacture, use and release of
chemicals into the environment. The quantitative data
used to develop risk estimates usually come from labo-
ratory animal studies employing relatively high dose
levels. Thus, both interpolation from high to low dose
levels and extrapolation from laboratory animals to
humans are required. The approach most widely used
for noncancer end points is to determine the no-ob-
served-adverse-effect level (NOAEL) for the critical
effect and then apply uncertainty factors (UFs) to ac-
count for scientific uncertainties in the total data base,
such as response variability within and between spe-
cies, the lack of chronic exposure data, and lack of a
NOAEL, etc. The resulting value is a reference dose
(RfD), the dose at or below which there is unlikely to be
any excess risk. Research is currently underway to fur-
ther develop and explore the application of such ap-
proaches.

During July and August of 1990, a differential optical
absorption spectrometer (DOAS) made by OPSIS Inc.
was used to measure gaseous air pollutants over three
separate open paths in Atlanta, GA. Over path 1 (1099
m) and path 2 (1824 m), ozone (O3), sulfur dioxide
(SO2), nitrogen dioxide (NO2), nitrous acid (HNO2),
formaldehyde (HCHO), benzene, toluene, and o-
xylene were measured. Nitric oxide (NO) and ammonia
(NH3) were monitored over path 3 (143 m). The data
quality and data capture depended on the compound
being measured and the path over which it was meas-
ured. Benzene, toluene, and o-xylene concentrations
measured over path 2, which crossed over an inter-
state highway, were higher than concentrations meas-
ured over path 1, implicating emissions from vehicles
on the highway as a significant source of these com-
pounds. Federal Reference Method (FRM) instru-
ments and a gas chromatograph (GC) were located
near the DOAS light receivers and operated concur-
rently. Correlation coefficients greater than 0.85 were
obtained between the DOAS and FRM's for O3, NO2,
and NO; however, there was a difference between the
mean values obtained by the two methods for O3 and
NO. Correlation coefficients of about 0.66 were ob-
tained between the DOAS and GC measurements of
benzene and o-xylene. However, the correlation coef-
ficient between the DOAS and GC measurements of
toluene averaged only 0.15 for the two DOAS meas-
urement paths. The lack of correlation and other fac-
tors indicate the possibility of a localized source of tol-
uene near the GC.

Alveolar macrophages (AM) store arachidpnic acid
(AA) which is esterified in cellular phospholipids until
liberated by phpspholipase A2 or C after exposure to
inflammatory stimuli. Following release, there can be
subsequent metabolism of AA into various potent, bio-
logical active mediators including prostagiandins and
platelet activating factor (PAF). To examine the possi-
bility that these mediators may account for some of the
pathophysiologic alterations seen in the lung following
O3 exposure, human AM were collected by bronchoal-
veolar lavage of normal subjects, plated into tissue cul-
ture dishes, and the adherent cells were incubated
with 3H-AA or 3H-lysoPAF. Human AM exposed 1.0
ppm O3 for 2 hr released 65 + or -12% more tritium,
derived from 3H-AA, than paired air-exposed controls
into media supernatants. In other studies using a simi-
lar 03 exposure protocol, there was also a significant
increase in human AM PGE2 production (2.0 + or - 0.5
fold-increase above air-exposure values, p<0.01,
n=17). In additional studies, using a similar O3 expo-
sure protocol (1.0 ppm for 1 hr), there was also a sig-
nificant increase in human AM PAF content (1.7 + or -

The median is a fundamental parameter in the area of
lifetime and survival statistics. In toxicodynamics the
LD50, lethal dose that results in 50% mortality, is fre-
quently used. The median is also used to describe the
incidence of cancer and other disease states. Factors
such as nutritional status, age of animal, and exposure
to a second chemical can cause the LD50 to shift. It is
therefore desirable to determine a functional relation-
ship between the median of a distribution and a cofac-
tor. The paper used SAS to examine the use of median
regression to predict a continuous dependent variable
as a function of a single cofactor and compare these
results to the standard ordinary least squares regres-
sion techniques. Two data sets were generated using
the SAS RANUNI and NORMAL functions. In one, the
median line was proportional to the mean line, and
both the median and mean had positive slopes with re-
spect to a cofactor. In the other, the slope of the
median line was positive while that of the mean line
was negative.

The study was initiated because annual runoff is
needed for several analyses being conducted by the
U.S. Environmental Protection Agency (EPA). The
study was concerned with the existence of a relation-
ship between annual runoff volume per unit area and
area; the reason underlying the relationship is unim-
portant. The variables were chosen based on the esti-
mation procedure used in previous studies. Thus, the
procedure of using runoff maps to estimate annual
runoff for the Southern Blue Ridge Province and
Northeast has no apparent bias due to watershed
area.

The paper discusses the development of new flyash/
lime sorbents for removing SO2 from coal-fired flue
gas. Flyash/lime weight ratios of 1:1 to 10:1 and sever-
al additives to these sorbents for promoting their reac-
tivity were evaluated in a bench-scale reactor simulat-
ing conditions in a fabric filter. Of the additives tested,
Na2HPO4.7H2O, (NH4)2HPO4, and H3PO4 signifi-
cantly enhanced the reactivity of the dry sorbents with
SO2. Alternative sources of silica were reacted with
lime, and the resultant dry sorbents were shown to be
highly reactive with SO2. Of the siliceous materials
tested, several diatomaceous earths, montmorillonitic
clays, and kaolins were identified as containing reac-
tive silica. The morphology of the sorbents developed
was characterized. The information, along with the re-
actor test results, was used to rate the sorbents for
pilot plant evaluation.

The paper discusses the performance and economics
of advanced electrostatic stimulation of fabric filtration
(AESFF), in which a high-voltage electrode is placed
coaxialty inside a filter bag to establish an electric field
between the electrode and the bag surface. The elec-
tric field alters the dust deposition pattern in the bag,
yielding a much lower pressure drop than that in a con-
ventional bag. Pilot plant results show that AESFF
bags can operate with a rate of pressure loss that is
70% below that for conventional bags. The presence
of the electric field also affects the aging characteris-
tics of the AESFF bags. On the average, the AESFF
bags had residual drags that were 10% below those of
conventional bags. The results show that AESFF
baghouses can yield the same pressure drop perform-
ance as conventional baghouses while operating at
much higher air/cloth ratios. An economic analysis
evaluated the capital, operating, and maintenance
costs for electric utility plants ranging from 200 to 1000
MW. For AESFF baghouses, the capital cost was
found to be 25 to 48% below that of a conventional
baghouse. A lifetime cost analysis predicts a net
present value for an AESFF baghouse that is 10 to
30% below that of a conventional baghouse.

The paper discusses research which evaluates the ap-
plication of adsorption techniques to the control of
indoor organic vapors. The adsorption on activated
carbon of three compounds representing three class-
es of organic species was studied at 30 C in the con-
centration range zero to 200 ppb using a microba-
lance. The three were benzene (aromatic), acetalde-
hyde (oxygenated aliphatic), and 1,1,1-trichloroethane
(halogenated aliphatic). Three sorbents (a wood base
carbon, a coal base carbon, and a coconut shell base
carbon) were examined. Uptakes for all the com-
pounds on all the carbons were low (on the order of 10
to the minus 7th power gmpl/g carbon). Simulation of
a packed bed of carbon indicated that carbon adsorp-
tion may not be practical for continuous removal, but
may be applicable to sudden releases (e.g., spills). Po-
tential alternatives to activated carbon adsorption are
discussed. Potentially toxic organic vapors are emitted
from a wide variety of building materials, consumer
products, and human activities. Control of indoor or-
ganic vapors generally involves removing the source
and/or increasing the ventilation rate. The ubiquitous
nature of sources of organic vapors generally makes
source removal impractical. Increased ventilation
causes increased energy usage with its resultant eco-
nomic penalties. Therefore, practical removal methods
are needed.

promote the rapid release of waste vapor into the kiln
environment. This rapid vapor release can deplete and
displace excess oxygen from the primary flame, and
form a puff, which can result in temporary failure of the
incinerator. Parametric studies on a specially designed
rotary kiln incinerator simulator showed that puffs are
very easily generated even with small quantities of
wastes and at excess air values exceeding 100%.
Furthrmore, their magnitudes and intensities increase
with increasing kiln tempere and rotation speed. A the-
oretical model describing simultaneous heat and mass
transfer into a sorbent aggregate, coupled with vapor-
pressure-driven waste vaporization within the sorbent
aggregate, was combined with a fragmentation model
and was able qualitatively to predict experimentally ob-
served effects relating to puff duration, kiln rotation
speed and temperature, and stoichiometric oxygen re-
quirement of the waste. The model was extrapolated
to conditions beyond the experimental test matrix.

There are over 200 industrial waste land treatment
sites in the United States, and a larger number of land
treatment sites for municipal wastewater and sludge
(Loehr and Malina, 1986). Land disposal of wastes has
increased during the past decade and is projected to
continue to increase in the future (Loehr and Malina,
1986). The study of organic chemicals in the soil envi-
ronment has been dominated by agricultural chemicals
(e.g., insecticides, nematicides and herbicides) and

bobwhite (Colinus virginianus). An initial oral dose of
methyl parathion (0, 3 or 6 mg/kg: O, O-dimethyl O-(4-

white before a 6-d food discrimination test; one group
was tested with a choice of food treated with 45 ppm
methyl parathion versus normal food and the second
with a choice of 90 ppm treated food versus normal
food. The average discrimination ratios (i.e., amount of
treated to untreated food consumed) were used to in-
dicate the chicks' ability to discriminate and avoid con-
taminated food. Chicks administered 6 mg/kg methyl
parathion did not discriminate between treated and un-
treated food at either food treatment level and initially
chose treated over untreated food (ratio=1.28;
p<0.05). Brain cholinesterase activity in the 6 mg/kg
groups averaged 50% of control levels, indicating high
exposure to methyl parathion, which correlated with a
behavioral disturbance (i.e.,preference for treated food
on day 1). Cholinesterase activity did not correlate with
the discrimination ratios throughout the remainder of
the 6-d exposure period due to the strong side prefer-
ence that developed in the treated groups. The study
demonstrates that feeding behavior and taste discrimi-
nation ability of bobwhite chicks was impaired due to
exposure to methyl parathion. (Copyright (c) 1989

The EPA Mobile Incinerator has demonstrated its abili-
ty to successfully destroy dioxin. A trial burn conducted
in 1987 demonstrated the incinerator's ability to de-
stroy a wide variety of compounds. The destruction
and removal efficiency (ORE) of carbon tetrachloride,
hexachloroethane, and trichlorobenzene was greater
than the required 99.99%, and the ORE for PCBs was
greater than the required 99.9999%. The field demon-
stration of the mobile incinerator that began in 1985 is
scheduled for completion in 1989 after incinerating
4,530,000 kg of waste material.

Chemically modified Ca(OH)2 sorbents for SO2 con-
trol in utility boilers were tested in an electrically
heated, bench-scale isothermal flow reactor, operated
at between 700 and 1000 C and residence times of
from 0.6 to 2 sec calculated from bulk gas flowrates.
Novel surfactant-modified Ca(OH)2 (SM-Ca(OH)2)
sorbents were compared to conventional Ca(OH)2
produced by dry hydration (DH-Ca(OH)2). Sorbents
were activated in the flow reactor. The gas composi-
tion was 5 vol % oxygen with the balance nitrogen. Ac-
tivated sorbents, SM-CaO and DH-CaO, were size
classified with an inertial cascade impactor down-
stream of the flow reactor. The structure of each sepa-
rated fraction (six trays plus preimpactor, D50 from
0.74 to > 11.9 micrometers) was characterized by ni-
trogen adsorption. For each size fraction measured,
the surface area was higher for SM-CaO than for DH-
CaO. The effect of thermal sintering was the increase
of median pore size as a result of eliminating fine pores
(below 100 A). Changes in the pore structure of
Ca(OH)2 sorbents reacting with SO2 were also investi-
gated. The effect of thermal sintering on pore structure
of sorbents reacting with SO2 was eliminated. The
degree of conversion was controlled by varying gas-
phase mass transfer resistance (SO2 concentrations
from 50 to 3000 ppm).

Di-(2-ethylhexyl) phthalate (DEHP) is a priority organic
pollutant frequently found in municipal sludges. A
greenhouse study was conducted to determine the ef-
fects of sludge on plant uptake of (14)C-DEHP (car-
bonyl labeled). Plants grown included three food chain
crops, lettuce (Lactuca sativa L.), carrot (Daucus
carota L.), and chile pepper (Capsicum annuum L.) and
tall fescue (Festuca arundinacea Schreb.). Net (14)C
concentration in plants grown in soil amended with
(14)C-DEHP-contaminated sludge was independent of
sludge rate (at the same DEHP loading) for lettuce,
chile fruit, and carrot roots. Net (14)C concentration,
however, was inversely related to sludge rate in carrot
tops, fescue, and chile plants. Intact DEHP was not de-
tected in plants by gas chromatography/mass spec-
trometry analysis. Calculated plant DEHP concentra-
tions based on measured net (14)C concentrations
and DEHP specific activities) were generally correlated
better with DEHP soil solution concentrations than
with total DEHP soil concentrations. Net (14)C-DEHP
bioconcentration factors were calculated from initial
soil DEHP concentration and plant fresh weights. Bio-
concentration factors ranged from 0.01 to 0.03 for
fescue, lettuce, carrots, and chile, suggesting little
DEHP uptake. Additionally, because intact DEHP was
not detected in any plants, DEHP uptake by plants was
of minor importance and would not limit sludge addi-
tions to the soils used to grow these crops. (Copyright

Rapid quantitative determination of di-(2-ethylhexyl)
phtnalate (DEHP) in municipal sludge is described for
capillary gas chromatography/mass spectrometry
(GC/MS) using selected ion monitoring with isotope di-
lution techniques. Propagation of error through a four-
step technique is measured as an increase in variance
with each additional step. Stepwise accumulated varia-
tion (as a percentage of total error) was GC/MS analy-
sis with data reduction, 3%; analyst (sample prepara-
tion), 8% heterogeneity of sludge, 30%; heterogeneity
in sludge-amended soil, 77%; and errors between
planters, 100%. The relative standard deviation (RSD)
associated with analysis of sludge alone was 16% at
51 mg/kg DEHP. Analysis precision was dependent on
sample size and DEHP concentration. The RSD for a
13 mg/kg DEHP loading in soil/sludge mixtures for a
greenhouse study was 26.5%. Detection limits for
DEHP in sludges with rapid screening procedures
were fixed by interfering extractable matrices.

One form of commercial application of microorga-
nisms, including genetically engineered microorga-
nisms is as an aerosol. To study the effect of aerosol-
induced stress on bacterial survival, nonrecombinant
spontaneous antibiotic-resistant mutants of four orga-
nisms, Enterobacter cloacae, Erwinia herbicola, Kleb-
siella planticola, and Pseudomonas syringae, were
sprayed in separate experiments in a greenhouse.
Samples were collected over a distance of 15 m from
the spray site for enumeration. Spores of Bacillus sub-
tilis were used as tracers to estimate the effects of dilu-
tion on changes in population over distance. Viable
counts of P. syringae, Enterobacter cloacae, and K.
planticola decreased significantly over a distance of 15
m. Erwinia herbicola showed no significant decline in
counts over the same distance. The degree of survival
of P. syringae during aerosoiization was dependent on
ambient environmental conditions (i.e.. temperature,
relative humidity), droplet size of the aerosol, and prior
preparative conditions. Survival was greatest at high
relative humidities (70 to 80%) and low temperatures
(12 C). Survival was reduced when small droplet sizes
were used. The process of washing the cells prior to
aerosoiization also caused a reduction in their survival.
Results from these experiments will be useful in devel-
oping sound methodologies to optimize enumeration
and for predicting the downwind dispersal of airborne
microorganisms, including genetically engineered
microorganisms. (Copyright (c) 1990, American Socie-

Maximum values of acid neutralizing capacity (ANC) in
Adirondack, New York lake outlets generally occur
during summer and autumn. During spring snowmelt,
transport of acidic water through acid-sensitive water-
sheds causes depression of upper lake water ANC. In
some systems lake outlet ANC reaches negative
values. The authors examined outlet water chemistry
from II Adirondack lakes during 1986 and 1987 snow-
melts. In these lakes, SO concentrations were diluted
during snowmelt and did not depress ANC. For lakes
with high baseline ANC values, springtime ANC de-
pressions were primarily accompanied by basic cation
dilution. For lakes with low baseline ANC, No in-
creases dominated ANC depressions. Lakes with in-
termediate baseline ANC were affected by both proc-
esses and exhibited larger ANC depressions. Ammoni-
um dilution only affected wetland systems. A model
predicting a linear relationship between outlet water
ANC minima and autumn ANC was inappropriate. To
assess watershed response to episodic acidification,
hydrologjc flow paths must be considered. (Copyright

Hexachlorobenzene (HCB) is a persistent environmen-
tal pollutant that bioaccumulates in tissues of marine
and fresh water fish. Once taken up by these tissues,
biodegradation is very slow with pentachlorophenol
and polar conjugates as possible metabolites in aquat-
ic organisms. Numerous studies have been done on
HCB uptake and depuration in fish. In these studies the
HCB bioconcentration factors (BCFs) varied from
5000 to 40,000 (wet weight basis) with half-lives (t 1 /2)
from a few days to several years. Although several
studies have examined HCB uptake in invertebrates,
only Oliver's (1987) study estimate a BCF. Oliver
(1987) found that the BCF of HCB in oligochaete
worms was 3120 when calculated on a wet weight
basis, with a t(1/2) of 27 days. However, in Oliver's
study the worms were buried in the contaminated sedi-
ment and the BCF calculated using the interstitial
water concentration. As a portion of the HCB body
burden was likely due to the ingestion of participates,
the reported BCF value may be in error.

Macrobenthic data from samples taken in 1980,1983
and 1985 along a pollution gradient in the Southern
California Bight (USA) were analyzed at 5 taxonomic
levels (species, genus, family, order, phylum) to deter-
mine the taxon and sample size sufficient for assess-
ing pollution impacts on 5 measures of community
structure. Two statistical designs were compared: a t-
test for differences between reference and impacted
stations where the error term was (1) among-year vari-
ation at the reference station (impact effects design),
(2) replicate (within-station) sampling error (location ef-
fects design). The estimated statistical power (1-Beta)
to detect impacts was a function of type and magni-
tude of impact, level of taxonomic identification, the
statistical design, and the sample size (ni = number of
sampling years at the reference station for the impact
effects design, and nl = number of replicate samples
per station for the location effects design). Four repli-
cate 0.1 sq m van Veen grabs per station were needed
to ensure community-wide, unbiased estimates of
Shannon's, 1-Simpson's and Mclntosh's Index.
Family-level identification appeared to be a good
choice for assessing pollution impacts at the study site
as it ensured a high probability (1-Beta > or = to 0.80)
of detecting intermediate or larger impacts on most
(impact effects design) or all (location effects design)
of 5 measures of community structure when ni and nl
> or = to 4, The level of taxonomic identification and
sample size should be considered along with other
sampling variables (e.g. sample unit size, sieve mesh
size) when seeking a statistically rigorous, cost-effec-
tive study design sufficient to meet pollution assess-
ment objectives.

The article discusses an evaluation of the effect of per-
cent outdoor air supplied and occupation level on the
particle size distributions and mass concentrations for
a typical office building. (NOTE: As attention has
become focused on indoor air pollution control, it has
become important to obtain basic information on the
effects of heating, ventilating, and air-conditioning
system parameters on office aerosols. In addition, it is
important to know the particle size distributions in a
typical office environment) The outdoor, return, and
supply air streams, as well as hallway air, were sam-
pled using measuring equipment covering particle di-
ameters from < 0.1 to > 10.0 micrometers. The mass
concentrations, when the building was occupied, in-
creased by a factor of about 2 when all return air was
used over all outdoor air. The concentrations when un-
occupied using no outdoor air were as low or lower
than were those when the building was occupied using
all outdoor air. All of the occupied concentrations were
< 200 micrometers/cu m. As expected, the outdoor
air was cleaner than the other streams. The next
lowest concentrations were for supply air, then return
air, with hallway air showing the highest concentra-
tions. The normalized number distributions had a
single mode consistently near 0.13 micrometer; the
volumetric distributions peaked at 0.3 micrometer.

A bacterium tentatively identified as an Erwinia sp. was
isolated from sewage by enrichment on menthanol
and lignin. Several mutants developed from this strain
were studied for their ability to degrade aromatic
ethers. Different concentrations of the chemicals were
incubated with the organisms and the degradation was
estimated by high-performance liquid chromatography
(HPLC). Among these mutants, one isolate, Erwinia sp.
strain CU3614, showed resistance to copper ions
(>20 mM CuSO4) and the ability to degrade 4-hydrox-
ydiphenyl ether (4-HDPE), 4-chlorodiphenyl ether (4-
CDPE), 4-nitrodiphenyl ether (4-NDPE), and 2,7-dich-
lorodibenzo-p-dioxin (2,7-DCDD) in the presence of
copper ions. Increased concentrations of copper in the
medium resulted in higher degradation of 4-HDPE.
Further studies with copper-sensitive mutants ob-
tained from Erwinia sp. CU3614 by Tn5 transppson-in-
duced mutagenesis showed a corresponding de-
crease in the ability to degrade 4-HDPE. These results
suggest the presence of copper-associated activity in
the biotransformation of aromatic ethers. (Copyright

It has been reported that tk-/- mutants recovered in
the mouse L5178Y TK + /- 3.7.2C mutagen assay
have often lost the tk+ allele. Allele loss in tk-/- mu-
tants is documented on Southern blots as the absence
of a 6.3-kb Nco I fragment seen in both tk+/+ and
tk+/- cell DMAs. For the routine screening of large-
and small-colony tk-/- mutant DNAs for the absence of
the genomic fragment, it has been found that cells can
be lysed in agarose plugs, and DNA of cells embedded
in plugs can be purified, restricted with Nco I, electro-
phoresed, and analyzed on Southern blots without sig-
nificant band distortion or diffusional loss of tk-specific
fragments in the 2- to 7-kb range. Purification and re-
striction analysis of DNA in agarose plugs, originally
developed to allow pulsed-field gel electrophoresis of
very large DNA fragments, represents a convenient al-
ternative to conventional DNA purification methods, al-
lowing quantitative recovery of DNA from small num-
bers of cells, eliminating centrifugation, phenol extrac-
tion, and ethanol precipitation steps, and requiring
smaller quantities of reagents. (Copyright (c) Elsevier

chitis were found in children from houses with HCHO

cially in children also exposed to environmental tobac-
co smoke. In children, levels of PEFR linearly de-
creased with HCHO exposure, with estimated de-

It is well known that pretreatment with the serine ester-
ase inhibitor phenylmethylsulfonyl fluoride (PMSF) can
protect experimental animals from organophosphorus-
induced delayed neurptoxicity (OPIDN), presumably by
blocking the active site of neurotoxic esterase (NTE)
such that binding and 'aging' of the neuropathic OP is
thwarted. The authors report here that while PMSF (60
mg/kg, s.c.) given 4 hours before the neuropathic OP
mipafox (50 mg/kg, i.m.) completely prevented the
clinical expression of OPIDN in hens, the identical
PMSF treatment markedly amplified the delayed neur-
otoxicity (relative to hens treated with the OP only) if
administed 4 hours after mipafox (5 or 50 mg/kg, i.m.).
Moreover, in a separate experiment using diisopropyl-
phosphorofluoridate (DFP) as the neurotoxicant in
place of mipafox, posttreatment with PMSF 4 hours
after DFP (0.5 mg/kg) also accentuated the severity of
the ataxia. These data indicate that PMSF only pro-
tects against OPIDN if given prior to exposure to the
neurotoxicant; treatment with PMSF after OP exposure
critically exacerbates the delayed neurotoxicity from
exposure to organophosphorus compounds. (Copy-

The paper presents a space-time localized adjoint
method (LAM) approximation for the advection-diffu-
sion transport equation. The formulation is based on a
space-time discretization in which specialized test
functions are defined. These functions locally satisfy
the homogeneous adjoint equation within each ele-
ment. The formulation leads to a general approxima-
tion that subsumes many specific methods based on
combined Lagrangian and Eulerian approaches, so-
called characteristic methods (CM's). The authors
refer to the method as an Eulerian-Lagrangian local-
ized adjoint method (ELLAM). The ELLAM approach
not only provides a unification of CM methods, but also
provides a systematic framework for incorporation of
boundary conditions in CM approximations. Example
calculations were presented to demonstrate that the
ELLAM procedure can handle all types of boundary
conditions.

The paper investigates the numerical behavior of
standard approximation methods for the unsaturated
flow equation. Solution using the h-based formulation
and a backward Euler time discretization is shown to
produce unacceptably large mass balance errors for
many example calculations. This is true for any iter-
ation method (Picard, Newton-Raphson, etc.). It is also
true for both finite difference and finite element ap-
proximations in space, although finite elements are
generally inferior to finite differences. A modified nu-
merical approach is proposed that alleviates the mass
balance problems discussed above. This approach is
based on a fully implicit (backward Euler) time approxi-

The hydrologic sensitivities of four medium-sized
mountainous catchments in the Sacramento and San
Joaquin River basins to long-term global warming were
analyzed. The hydrologic response of these catch-
ments, all of which are dominated by spring snowmelt
runoff, were simulated by the coupling of the snowmelt
and the soil moisture accounting models of the U.S.
National Weather Service River Forecast System. In
all four catchments the global warming pattern, which
was indexed to CO2 doubling scenarios simulated by
three (global) general circulation models, produced a
major seasonal shift in the snow accumulation pattern.
Under the alternative climate scenarios more winter
precipitation fell as rain instead of snow, and winter
runoff increased while spring snowmett runoff de-
creased. In addition, large increases in the annual
flood maxima were simulated, primarily due to an in-
crease in rain-on-snow events, with the time of ocur-
rence of many large floods shifting from spring to
winter. (Copyright (c) 1990 by the American Geophysi-

Plant uptake of sludge-borne potychlorinated biphen-
yls (PCBs) (similar to Aroclor 1248) was evaluated in a
greenhouse study with two food-chain crops and a
grass species. Polychlorinated biphenyl loading to two
soils was varied in one experiment by adding different
rates of a municipal sewage sludge heavily contami-
nated (52 mg/kg) with PCBs. In a second experiment,
Aroclor 1248 was spiked into unamended soils or soils
amended with another sludge containing <1 mg/kg
PCBs. Analysis of PCBs was by GC/MS with a reliable
detection limit in plants of 20 microg/kg for individual
chlorinated classes (tri, tetra-, and pentachlorobiphen-
yls) and total PCBs. Only carrots (Daucus carota) were
contaminated with PCBs, and contamination was re-
stricted to carrot peels. Current USEPA guidelines for
land application of sludges based on sludge PCB con-
tent are shown to be extremely conservative.

Toluene is a priority pollutant that can be introduced to
soils in a variety of wastes, including some municipal
sludges. Laboratory experiments were conducted to
study the behavior of toluene in two soils in the pres-
ence and absence of municipal sludge. Sludge addi-
tions increased toluene adsorption in two soils be-
cause of increased organic C content. The source of
organic C (soil or sludge) and soil clay content also in-
fluenced toluene adsorption. Toluene adsorption-de-
sorption was reversible in one soil, but slightly hystere-
tic in the other soil. An air-flow incubation system was
used to evaluate toluene volatilization and degrada-
tion. The primary fate of surface-applied toluene in
both soils was volatilization. Toluene volatilization
rates were independent of sludge treatments. Toluene
degradation was negligible in all treatments because
of rapid volatilization losses. Despite increased tolu-
ene adsorption in the presence of sludge and reduced
volatilization in saturated soils, gaseous transfer domi-
nated all soils and treatments so that no toluene re-
mained after 10 d.

Sorption and degradation of pentachlorophenol (PCP)
by two alkaline and one acid soil was studied in the
presence and absence of sewage sludge. The PCP
concentrations used (0.1-10 mg/kg) included PCP
rates expected with land application of normal munici-
pal sewage sludges. Sorption/desorption isotherms,
derived using batch equilibrium techniques, were de-
scribed by the freundlich equation. The PCP sorption
increased with increasing sludge additions. Desorption
in the alkaline soils was completely reversible and no
irreversible residues were formed. Leaching of PCP
would be most likely in the unamended alkaline soils.
Degradation of PCP at low (0.75 mg/kg) initial concen-
tration was rapid (t(sub 1/2) approximately equal to
10-15 d) in alkaline soils, but much slower (t(sub 112)
approximately equal to 38 d) in the acid soils. Sludge
additions to the soils did not substantially affect PCP
degradation. More rapid degradation of PCP in the al-
kaline vs. acid soils was attributed to less sorption and
more favorable conditions for microbial activity. Rapid
degradation in the alkaline soil, and greater sorption in
the acid soil, reduces the chance of PCP leaching.
However, longer PCP residence times in the acid soil
increase the possibility for plant uptake.

A greenhouse study was conducted to determine the
effects of sludge on plant uptake of 14C-pentachloro-
phenol (PCP). Plants included all fescue (Festuca
arundinacea Schreb.), lettuce (Latuca saliva L), carrot
(Daucus carota L), and chile pepper (Capsicum
annum L.). Minimal intact PCP was detected in the
fescue and lettuce by gas chromatography/mass
spectrometry (GC/MS) analysis. No intact PCP was
detected in the carrot tissue extracts. Chile pepper
was not analyzed for intact PCP because methylene
chloride extracts contained minimal 14C. The GC/MS
analysis of soil extracts at harvest suggests a half-life
of PCP of about 10 d independent of sludge rate or
PCP loading rate. Rapid degradation of PCP in the soil
apparently limited PCP availability to the plant. Biocon-
centration factors (dry plant wt./initial soil PCP con-
centration) based on intact PCP were <0.01 for all
crops, suggesting little PCP uptake. Thus, food-chain
crop PCP uptake in these alkaline soils should not limit
land application of sludge.

2,4-Dinitrophenol (DNP) is a moderately weak acid that
is expected to be highly labile (leachable and plant
available) in high-pH soils. The adsorption and degra-
dation behavior of DNP in two sludge-amended, cal-
careous soils was determined and used to explain
DNP uptake by plants grown in the soils in the green-
house. The DNP adsorption was minor in both soils
and was only slightly affected by sludge. The DNP deg-
radation was rapid in both soils and was unaffected by
sludge. Thus, despite limited soil adsorption, plant
uptake of DNP was minor in all crops and plant parts
owing to rapid soil DNP degradation. Even if a munici-
pal sludge highly contaminated with DNP was identi-
fied (an unlikely occurrence), concerns over possible
plant contamination should not limit sludge applica-
tions to calcareous soils or leaching of DNP to ground-
water, given careful water management.

Because the performance of powdered activated
carbon (PAG) for uses other than taste and odor con-
trol is poorly documented, the purpose of the article is
to critically review uses that have been reported and to
analyze means of employing PAC more efficiently. The
extent of adsorption of synthetic organic chemicals on
PAC is strongly dependent on the type of compound
being removed. The reported removals of trihalometh-
anes and trihalomethane precursors by PAC range
from poor to very good. In selecting the point of addi-
tion of PAC, consideration must be given to the degree

Phosgene is a pulmonary toxicant that can produce
lung edema, bronchoconstriction, and immune sup-
pression following an acute exposure. In the report,
the effects of acute in vivo and in vitro phosgene expo-
sure on lung arachidonic acid metabolism were exam-
ined. Fischer-344 rats were exposed either to air or to
phosgene (0.05-1.0 ppm) for 4 hr and the lungs la-
vaged at 0.4,20, and 44 hr post exposure. Leukotriene
B4 (LTB4), leukotrienes C4, D4, and E4 (LTC4/D4/
E4), and prostaglandin E2 (PGE2) were measured in
lavage fluid by radioimmunoassay. With the exception
of the LTC4/D4/E4 concentration in 1.0 ppm phos-
gene-exposed rats, in vivo phosgene exposure at > or
= 0.1 ppm produced significant decreases in the con-
centrations of PGE2, LTB4, and LTC4/D4/E4 in the
lavage fluid collected immediately after exposure.
Temporally associated with the decreased eicosanoid
production was a smaller number of alveolar macro-
phages recovered in the lavage fluid of phosgene-ex-
posed rats. Dose response studies were performed.
Phosgene exposure in vitro of rat and human alveolar
macrophages was then performed to determine if the
toxicant could directly inhibit the formation of eicosan-
oids by alveolar macrophages.

Acute or repeated (14 days) intragastric administration
of L-d-aspartyl-L-phenyla-lanine methyl ester sus-
pended in saline and Tween-80 in doses of up to 1,000
mg/kg had no significant effect in male Fischer-344
rats on routine measures of sensorimotor function, in-
cluding spontaneous motor activity, acoustic startle
reflex and prepulse inhibition. Other experiments
found that aspartame (500 or 1,000 mg/kg) had no sig-
nificant effect on acquisition of passive or active avoid-
ance or a spatial, reference memory task in the Morris
water maze. A series of separate studies found that
aspartame had no effects in rats fasted 24 hours prior
to testing, or if it were suspended in carboxymethylcel-
lulose or administered by the intraperitoneal route.
Under the conditions of these experiments, large
doses of aspartame have no significant neurobiologi-
cal effects in adult rats as measured by procedures
known to be sensitive to the neurobiological effects of
neurotoxicants, including convulsants, organochlorine
insecticides and heavy metals.

The possible effects of climate change on the com-
bined Central Valley Project-California State Water
Project (CVP/SWP) were evaluated using a three-
stage approach. In the first stage, runoff from four
headwater 'study catchments' was simulated using
rainfall/snowmelt-runoff models, with climatic input
taken from CO2 doubling scenarios from three general
circulation models (GCMs). In the second stage, long-
term inflows to the CVP/SWP reservoir system were
simulated, conditioned on the study catchment flows,
using a stochastic disaggregation model. In the third
stage, a system simulation model was used to evalu-
ate the performance of the reservoir system. For all of
the alternative climate scenarios, runoff would be shift-
ed from the spring to the winter. Significantly lower
water deliveries from the SWP would occur under the
CO2 doubling scenarios. The reduced deliveries would
occur because some of the increased winter runoff
would be spilled from the reservoirs instead of being
stored in the snowpact, even though the mean annual
runoff increased slightly under some climate scenar-

The most common process for remediating contami-
nated ground water is extraction and treatment. Data
from 19 on-going and completed ground water extrac-
tion systems were collected and analyzed to evaluate
the effectiveness of this process in achieving cleanup
concentration goals for ground water. This analysis in-
dicated several trends including: containment of
ground water plumes was usually achieved; contami-
nant concentrations dropped significantly initially fol-
lowed by a leveling out; after the period of initial rapid
decline, the continued decreases in concentration
were usually slower than anticipated; and certain data
important to optimizing system design and operation
had often not been collected during the site character-
ization phase. Factors limiting the achievement of
cleanup concentration goals fell into four basic catego-
ries: hydrogeological factors; contaminant-related fac-
tors; continued migration from source areas and the
size of the plume itself; and system design factors. The
findings of the study indicate that ground water extrac-
tion is an effective method for preventing additional mi-
gration of contaminant plumes and achieving risk re-
duction. However, the findings indicate that in many
situations, it may not be practicable to rely solely on
ground water extraction and treatment to achieve
health-based cleanup concentrations throughout the
contaminated zone and fulfill the primary goal of re-
turning ground water to beneficial use. This suggests
several recommendations for improving ground water
response actions including: actions to contain con-
taminant plumes should be initiated early; data on ver-
tical variation of hydraulic conductivity, distribution of
the contaminant mass, and partitioning of contami-
nants to soil or a stationary phase in the saturated
zone should generally be collected as part of the site
characterization process; remedial actions should be
implemented in stages to better utilize information on
aquifer response as the system is being designed and
implemented; remedial actions should be monitored
and modified during operation to optimize system effi-
ciency; and methods to enhance extraction effective-
ness and efficiency should be considered.

EPA PUBLICATIONS BIBLIOGRAPHY
The package, referred to as 'Strawman II', is a working
document that represents EPA's latest staff position
on an effective program to regulate wastes and other
materials uniquely associated with noncoal mining.
Strawman II does not represent a proposed rule. The
package consists of two parts: (1) the Foreward, which
describes the pre-rulemaking Strawman process, a
background and overview of the mining waste program
as envisioned in the package, and discussions of
major issues concerning the program and its scope;
and (2) the Regulatory Approach, presented as '40
CFR XXX, XXY, and XXZ' to reflect how the program
might appear in regulatory language. Discussions and
amplifications of specific points are also interspersed
throughout the Regulatory Approach. EPA encourages
all interested parties to convey their views on any and
all aspects of the program concept.

erated by contributing States, Canada, Mexico, and
the Pan American Health Organization are reported in
the ERD when available. The ERAMS is comprised of
nationwide sampling stations that provide air, surface
and drinking water and milk samples from which envi-
ronmental radiation levels are derived. Sampling loca-
tions are selected to provide optimal population cover-
age while functioning to monitor fallout from nuclear
devices and other forms of radioactive contamination
of the environment. The radiation analyses performed
on these samples include gross alpha and gross beta

The passive nature of activated charcoal allows both
adsorption and desorption of radon, and since the ad-
sorbed radon under goes radioactive decay during the
exposure period, the ability of the non-diffusion barrier
(open-faced) canister to uniformly integrate over the
entire exposure period can be impaired. To help allevi-
ate the problem, the EPA open-face canister was
modified by inserting a polyethylene membrane be-
tween the retaining screen and the carbon bed. This
decreased the water vapor and radon adsorbed by the
carbon, reduced the rate of adsorption/desorption be-
tween the carbon and the environmental, and im-
proved integration capability.

The U.S. Environmental Protection Agency (EPA) has
funded a pilot project to assist small- and medium-size
manufacturers who want to minimize their generation
of hazardous waste but who lack the expertise to do
so. Waste Minimization Assessment Centers
(WMACs) were established at selected universities
and procedures were adapted from the EPA Waste
Minimization Opportunity Assessment Manual (EPA/
625/7-88/003, July 1988). The WMAC team at the
University of Tennessee performed an assessment at
a plant manufacturing printed plastic bags for snack
foods-approximately 1.8 million Ib/yr. Plastic stock is
ink printed and oven cured. To make single-layer bags,
a heat seal process is used, and the bags are then
packaged and shipped. For certain products, a plastic
or metalized film is laminated to the printed plastic film,
the rolls are slit to obtain individual bags, and the bags
are packaged and shipped. The team's report, detail-
ing findings and recommendations, indicated the most
waste was generated in the lamination process and
that the greatest savings could be obtained by install-
ing an automatic adhesive/solvent mixing system to
reduce (75%) the waste from the unused metalized
film adhesive/solvent mixture.

Recently there has been legislation to limit the dis-
charge of litter into the aquatic environment. The U.S.
EPA Office of Water has responded by implementing
pilot studies to detect changes in trends of litter in the
aquatic environment associated with the implementa-
tion of legislation. A general survey design for detect-
ing changes in trend of aquatic litter on the nation's
shorelines was presented. Specific recommendations
for number of survey units and frequency of sampling
depend on required confidence and power as well as
study-specific economic constraints. The particular
model used for sample size calculation is based on
normally distributed errors and efforts should be made
to validate the model. With a planned survey, impacts
of legislation and educational efforts in reducing aquat-
ic litter can be evaluated.

A limited-scale indoor air quality investigation was con-
ducted over a 4 day period at the North Carolina De-
partment of Environment, Health, and Natural Re-
sources' offices located at 3800 Barrett Drive, Raleigh,
NC. Integrated 9 hour particle, aldehyde, and volatile
organic compound samples were collected at three
different monitoring sites during normal office hours.
Continuous temperature, relative humidity, and carbon
dioxide measurements were also recorded. The limited
study results indicate that the office's indoor air quality
during the monitoring study was acceptable. However,
periods when indoor temperatures and carbon dioxide
levels reached or exceeded the American Society of
Heating Refrigerating and Air Conditioning Engineers'
guidelines were noted. Targeted volatile organic com-
pound and aldehyde concentrations were low, with all
species concentrations well below any established ex-
posure limit. In many cases, the organic species con-
centrations were at or below the analytical detection
limit. Commonly observed species (e.g., trichloroethy-
lene, toluene, formaldehyde) were measured at con-
centrations similar to the levels reported by other
indoor air investigators in office buildings. The study
results suggests no significant sources of indoor air
contaminants. Minor modifications to the heating and
ventilation system may be needed to increase the per-
centage of outside air, provide increased total air flow,
and provide better control for indoor temperatures.

The report examines the data quality achieved during a
field study implemented by the EPA's Wetland Re-
search Program (WRP) at the Environmental Re-
search Laboratory in Corvallis, Oregon. The project
was conducted by Connecticut College as part of the
WRP's ongoing research on created wetlands. It was
one of three pilot projects aimed at developing meth-
ods for comparing natural wetlands with created wet-
lands. Soils, vegetation, hydrology, and site morpholo-
gy data were recorded. Root specimens were collect-
ed and tested for the presence of vescular-arbuscular
mycorrhizae. In addition, each site was surveyed,
mapped, and photographed. One objective of the
study was to identify field procedures which correctly
differentiated wetlands based on their structural char-
acteristics. High quality field data is required to distin-
guish environmental differences between sites, s ex-
tensive data quality assessments were included.
Wherever possible, field procedures were evaluated
for data errors occurring during sample collection, data
recording, sample storage, and analysis. The report
outlines the data quality assessment procedures used
and summarizes the results of the assessment.

Bench-scale biotreatability studies were performed to
determine the most effective of two bioremediation ap-
plication strategies to ameliorate creosote- and pen-
tachlorophenol (PCP)-contaminated soils present at
the American Creosote Works Superfund site, Pensa-
cola, Florida: solid-phase bioremediation or slurry-
phase bioremediation. When indigenous microorga-
nisms were employed as biocatalysts, solid-phase
bioremediation was slow and ineffective (8-12 weeks
required to biodegrade >50% of resident organics).
Biodegradation was limited to lower-molecular-weight
constituents rather than the more hazardous, higher-
molecular-weight (HMW) compounds; POP and HMW
polycyclic aromatic hydrocarbons (PAHs) containing 4
or more fused rings resisted biological attach. More-
over, supplementation with aqueous solution of inor-
ganic nutrients had little effect on the overall effective-
ness of the treatment strategy. Alternatively, slurry-
phase bioremediation was much more effective:
>50% of targeted organics were biodegraded in 14
days. Again, however, more persistent contaminants,
such as PGP and HMW PAHs, were not extensively
degraded when subjected to the action of indigenous
microorganisms.

EPA's Wetland Research Program has supported a
major effort to study wetlands mitigation projects in the
field. The field studies were designed to: (1) evaluate
the project plans; (2) compare the projects with natural
wetlands in the same land use setting; and (3) describe
the development of the projects over time. The infor-
mation from the studies will be used as technical guid-
ance for setting performance criteria and developing
design guidelines for mitigation projects. Pilot studies
have been conducted in Oregon, Washington, Florida,
and Connecticut. The report presents the methods
and associated quality assurance procedures used
during the Connecticut study. A major objective of the
pilot study was to evaluate the field procedures and
the data quality assessment protocols used. The au-
thors are in the process of performing that evaluation.
They anticipate that in some cases they will adopt the
procedure, while others will be refined or discarded.
Therefore, the authors caution the user of the docu-
ment that, at this point, the EPA makes no claims or
endorsement of the use of the field, laboratory, or data
quality assessment procedures associated with the
study.

In response to a Congressional mandate, a study was
undertaken by the Office of Research and Develop-
ment to monitor several metal and organic pollutants
in air and other environmental media near the Rutland,
Vermont Municipal Waste Combustor (MWC) facility;
and to estimate the magnitude of any increases in
health risk. As data became available, it became ap-
parent that there was no obvious relationship between
the operation of the MWC and ambient air pollution
levels. Therefore, the focus of the study shifted from
one of health risk assessment to one of more sophisti-
cated statistical analysis to determine whether any in-
fluence of the MWC was detectable. The final report
(EPA/600/8-91/007) was intended as a summary of

Sound Study, The New York-New Jersey Harbor Estu-
ary Program; and The New York Bight Restoration

since the regulated community will be required to im-
plement provisions contained in all three plans, there
is a compelling need for inter-plan coordination. For
this reason, on March 12-14, 1990, the Management
Conferences, in conjunction with Manhattan College
and their 50th anniversary of environmental engineer-

The technical resource document provides recom-
mended procedures for evaluating the effectiveness of
liquid transmission control systems for hazardous
waste landfill and surface impoundments. The proce-
dures described allow an evaluates to determine the
performance of (1) compacted day liners intended to
impede the vertical flow of liquids, (2) sand or gravel
drainage layers used to convey liquids laterally into
collection systems (3) slopes on such liner/drain
layers, and (4) spacings of collector drain pipes. The
mathematical principles that describe the transport of
liquids through hazardous waste landfills and surface
impoundments are technically complex. Faced with
the situation, it is tempting to circumvent these difficul-
ties by reverting to empiricism or rules of thumb. In the
manual, however, this has been avoided by using lin-
earized versions of complicated mathematical equa-
tions and by using simplified boundary conditions.
Thus, the evaluator is able to assess the performance
of a design using algebraic equations.

(14)Odioxin tracers were used to evaluate whole MMS
sampling train recoveries of dioxin and to determine
the distribution of dioxins spiked into a sampling train
that was concurrently sampling emissions from a burn
of either natural gas ('clean' bum) or kerosene ('dirty'
burn). The spike tests were made with a pilot-scale fur-
nace constructed and operated in the laboratory. Re-
covery of (14)C-dioxin from the MMS sampling train
was determined by scintillation spectrometry. The ex-
perimental results indicate that the amount of spiked
TCDD-(14)C recovered was approximately 85% during
a natural gas test and 83% during a kerosene test. The
amount of spiked OCDD-(14)C recovered was approxi-
mately 88% during a kerosene test. Also, the data indi-
cate that during the kerosene tests OCDD-(14)C is col-
lected primarily in the front half of the sampling train
but TCDD-(14)C is often found in the XAD and the rear
filter bell, riser and condenser of the sampling train.
During the natural gas tests, TCDD-(14)C was primarily
in the XAD. The distribution of the TCDD-(14)C in the
kerosene tests was dependent on the rigid operation
of the sampling train. The information from the study
will be used to determine procedural areas that need
improvements or modifications to allow the efficient
collection and accurate determination of trace levels
of dioxins and furans using the MMS Method.

Parameters which were expected to control the re-
moval process of VOCs from contaminated soil during
the SVE operation were studied by means of numerical
simulations and laboratory experiments in the project
Experimental results of SVE with soil columns in the
laboratory indicated that the removal efficiency of
VOCs from soil columns was a complicated function of
air flow and the hydrogeometry inside. The partition
process between air and the immobile liquid was not
an equilibrium one, and the interfacial mass transfer
varied with the residual amount of VOCs in the soil. Ad-
ditional experiments under various conditions should
be conducted to obtain further insight into SVE proc-
ess. Two computer models were developed to study
soil air and VOC movement during the SVE process.
The first one was an analytical approximate model
which could be used for the simulation of air move-
ment in the SVE operation with multiple wells in homo-
geneous soil media. The second one was a numerical
model in three-dimensional geometry which used a
finite difference solution scheme. A simple pneumatic
pump test was conducted, and part of test data were
used for the validation of the simple analytical model.

A SITE Demonstration of the Toxic Treatment (USA)
Inc. in-situ steam/hot-air stripping technology (Detoxi-
fier) was conducted beginning in the fall of 1989 at the
GATX Annex Terminal site located in San Pedro, CA.
The chemical storage and transfer facility was con-
taminated with various solvents due to spillage and a
fire. Contamination extended into the salt water table
(1.8 meters). Based on the SITE Demonstration and
other data, K was concluded that 85% of the volatile
organic compounds and 50% of the semivolatile or-
ganic compounds were removed from the soil. Fugitive
air emissions are very low, and lateral and downward
migration of contaminants due to the treatment were
minimal. Finally, it was concluded that this in-situ proc-
ess is cost competitive.

To determine whether ground-water contamination
has occurred or remediation efforts have been effec-
tive, it is necessary to collect ground-water samples in
such a way that the samples are representative of
ground-water conditions. Unfortunately, formation of
stagnant water within conventional monitoring wells
requires that these wells be purged prior to sampling, a
procedure that may introduce significant bias into the
determination of concentrations of sensitive constitu-
ents such as volatile organic compounds (VOCs). The
use of in situ ground-water sampling devices, which
minimize or eliminate the need for well purging, may
help alleviate some of the difficulties associated with
sampling ground-water at hazardous waste sites. In
the study, several ground-water sampling devices, in-
cluding two in situ systems, were field-tested to deter-
mine their capability for yielding representative VOC
data. Sampling devices included a bladder pump, a
bladder pump below an inflatable packer, a bailer, a
bailer with a bottom-emptying device, an in situ West-
bay MP System, two in situ BAT devices, and a proto-
type BAT well probe. The devices were field-tested at
a site contaminated by a VOC plume, and the compari-
son was based on the ability of the devices to recover
representative concentrations of the VOCs. The re-
sults of the study indicate that the tested in situ de-
vices may eliminate the need for well purging prior to
sample collection and that the resulting samples are at
least as representative as those collected with a blad-
der pump in a conventional monitoring well.

Weekly average atmospheric concentrations of sul-
fate, nitrate, ammonium, sulfur dioxide, and nitric acid
were measured (using three stage filter packs)
throughout the year, while sodium, potassium, calcium,
and magnesium were measured from January through
September. Results showed species-dependent varia-

much higher (factor 5-10) at eastern sites than at west-
em. On the other hand, NO3(-), Na(+), K(+), Ca(+2),
and Mg(+2) concentrations were frequently compara-
ble at eastern and western sites. Average SO4(-2),
NH4(+), and HNO3 concentrations were typically
highest during summer and lowest during fall. In con-
trast, SO2 and NO3(-) were highest in winter and
lowest in summer. Day/night variability was low for
aerosols, but frequently pronounced for SO2 and
HNO3, especially during the summer and at sites sur-
rounded by complex terrain. Ozone data for 1988 and
1989 showed marked differences between years, with
notably higher concentrations in 1988. Approximations
of annual dry deposition rates for SO4(-2), SO2, NO3(-
), and HNO3 suggest that gaseous deposition greatly
exceeds aerosol deposition and that dry fluxes are
similar to wet deposition at numerous sites in the east-
em U.S. Application of site-specific dry deposition
models are needed to refine these estimates.

Hydraulic fracturing, a method of increasing fluid flow
within the subsurface, should improve the effective-
ness of several remedial techniques, including pump
and treat, vapor extraction, bio-remediation, and soil-
flushing. The technique is widely used to increase the
yields of oil wells, but is untested under conditions typi-
cal of contaminated sites. The project consisted of lab-
oratory experiments, where hydraulic fractures were
created in a triaxial pressure cell, and two field tests,
where fractures were created at shallow depths in soil.
The lab tests showed that hydraulic fractures are read-
ily created in clayey silt, even when it is saturated and
loosely-consolidated. Many of the lab observations
can be explained using parameters and analyses
based on linear elastic fracture mechanics. Following
the field tests, the vicinity of the boreholes was exca-
vated to reveal details of the hydraulic fractures. Maxi-
mum lengths of the fractures, as measured from the
borehold to the leading edge, averaged 4.0 m, and the
average area was 19 sq m. Maximum thickness of
sand ranged from 2 to 20 mm, averaging 11 mm. As
many as four fractures were created from a single bor-
ehold, stacked one over the other at vertical spacing of
15 to 30 cm.

contains regional analyses of the results across all
catchments in the northeastern and southeastern re-
gions. The summaries are given for all catchments in
each region for which successful calibrations of
MAGIC were obtained. The catchment data are drawn
from the results files forwarded to Corvallis. The cali-
bration protocol for MAGIC applied to the DDRP catch-
ments involved multiple calibrations for each catch-
ment. Ten calibrations were attempted for each catch-
ment. A catchment was not considered calibrated until
at least three calibrations were successful. The multi-
ple calibrations were performed in order to estimate
the uncertainty in the calibrated model for each catch-
ment. The procedure is described in detail in another
volume. Because multiple calibrations are available for
each catchment, the results summarized here for sim-
ulated values (or changes in simulated values) are the
median (MED) values of all calibrations for an individ-
ual catchment. The uncertainies in simulated values
(or changes in simulated values) are presented as the
difference in the maximum and minimum (MX-MN)
values resulting from the multiple calibrations.

bustor (MWC) in Rutland, Vermont. Samples were col-
lected between October 1987 and February 1989 at or
near locations predicted to have maximum deposition.
The measured pollutant concentrations could not be
correlated with the emissions or operation of the
MWC. Evidence for this conclusion comes from both
qualitative and quantitative evaluation of the measured
pollutant concentrations in the ambient air and envi-
ronmental media, as well as comparison with predicted
ambient air concentrations of the pollutants using local
meteorologic information.

The removal of a natural mixture of As(lll) (31 micro-
grams/L) and As(V) (57 micrograms/L) from a ground-
water high in total dissolved solids (TDS), and also
containing fluoride (2.0 mg/L), was studied in San
Ysidro, NM using the University of Houston (UH)/U.S.
Environmental Protection Agency (EPA) Mobile Drink-
ing Water Treatment Research Facility. The objective
of the study was to establish a cost-effective means of
removing As(lll), As(V), and fluoride from this and simi-
lar waters. Arsenic adsorption into fine-mesh activated
alumina gave better-than-expected results. Approxi-
mately 9000 bed volumes (BV) could be treated at pH
6 before the arsenic maximum contaminant level
(MCL) (0.05 mg/L) was reached. At the natural pH of
7.2, however, only 1900 BV could be treated before
exceeding the MCL Reverse Osmosis (RO) treatment
resulted in > 97% arsenic removal and > 94% TDS re-
moval. Electrodialysis (ED) removed 73% of the ar-
senic and was able to meet the arsenic MCL on the
City Water containing 89 micrograms/L total arsenic;
however, ED removed only 28% of the As(lll) from a
new well containing 100% As(lll) at a level of 230 mi-
crograms/L. Chloride-form anion exchange also per-
formed better-than-expected (200 BV) but not well
enough for it to be considered seriously for treatment

The sorption of ionizable organic compounds to sedi-
ments and saturated soils is examined. The sorption of
pentachlorophenol to two sediment silt-clay fractions
as a function of pH is described. Sorption of both the
neutral and the ionic species was shown to occur; re-
sults were quantitatively interpreted by accounting for
sorption of both the neutral and ionic species and by
accounting for acid dissociation in the aqueous phase.
In addition, factors influencing the sorption of several
organic bases to sediments are described, as well as
some of the inherent difficulties encountered in apply-
ing phenomenological data to distinguish among vari-
ous physical and chemical processes. Finally, proc-
esses influencing the distribution of neutral and anion-

cal structures, all second order rate constants that
have been measured under conditions that make the
values comparable have been extracted from the liter-
ature and combined with rate constants not reported
before to compile a comprehensive list of second
order rate constants for chemicals of diverse struc-
tures. Chemicals for which constants are presented in-
clude seven chlorinated carboxylic acid esters of 2,4-
dichlqrophenoxyacetic acid (2,4-D), phenol and seven
substituted phenols, three phthalate esters, three ani-
lines, seven amides, and seven acetanilides. The 35
constants were measured in the laboratory by a proto-
col that measures disappearance of the chemical sub-
strate as a function of time in the presence of suspend-
ed natural populations from unpolluted aquatic sys-

In 1973, the U.S. Environmental Protection Agency's
Office of Radiation Programs established the Environ-
mental Radiation Ambient Monitoring System
(ERAMS) to provide continuous, accurate, and usable
environmental radiation data to the public. For com-
pleteness, ERAMS data for all specific radionuclide
analyses are reported as the calculated results indi-
cate, whether the numbers are negative, zero, or posi-
tive. Frequently, there is little or no radioactivity in envi-
ronmental media. Thus, tne results of laboratory analy-
ses should statistically show a distribution of negative
and positive numbers about zero. A negative value
occurs when a previously determined background
value is subtracted from n sample value that is less
than that of the background. Prior to July 1975,
ERAMS data were not reported numerically when the
results were less than a specified reporting level or
minimum detectable level. The present reporting pro-
cedure allows all the data to be reported and evaluat-
ed statistically without an arbitrary cutoff of small or
negative numbers. The approach will facilitate esti-
mates of bias in the nuclide analyses and will allow
better evaluation of distributions and trends in environ-
mental data.

tained from previous studies by the agency. Section 2
presents the conclusions of the study. Section 3 pre-
sents a description of the vapor phase adsorption
process, discusses impacts of changes in inlet vent
stream characteristics on adsorber performance, and
presents supporting test data. Section 4 presents a de-

The paper describes the effects of fly ash recycle in
dry scrubbing. (Previous workers have shown that the
recycle of product solids improves the utilization of
slaked lime-Ca(OH)2-for sulfur dioxide (SO2) remov-
al by spray dryers with bag filters.) In laboratory-scale
experiments with a packed-bed reactor, utilization was
increased several-fold when the Ca(OH)2 was first
slurried with one of several different fly ashes. The en-
hancement increased with the higher loading of fly
ash-g fly ash/g Ca(OH)2. Much higher Ca(OH)2 utili-
zation was achieved when silic acid was used instead
of fly ash. Scanning electron microscopy supports the
explanation that Ca(OH)2 and silica dissolve and re-
precipitate as a more reactive calcium silicate. Other
major constituents of fly ash have less or no effect at
all on Ca(OH)2 utilization. The amount of calcium in
the fly ash did not affect the overall SO2 removal after
Ca(OH)2 was added. Slurrying for longer than 2 hours
at higher than 60 C can improve the utilization of
Ca(OH)2 slurried with fly ash.

A generalized soft water acidification model has been
developed. The enhanced trickle-down (ETD) rrottel is
driven by precipitation, evaporation, acidity sulfate,
and chloride loading time series daily input c.dta. The
hydrologic component simulates snowmeli, interflow,
overland flow, groundwater flow, frozen ground proc-
esses, seepage, and evapotranspiration. Physico-
chemical and biological processes that affect the alka-
linity or sulfate balance and are included in the formu-
lation are cation exchange, chemical weathering, sul-
fate sorption, and sulfate reduction. The system of 20
ordinary differential equations is solved by using a van-
able time step fourth-order predictor-corrector numeri-
cal scheme. Shown here is calibration of the ETD
model for two lakes in the Adirondack Park of New
York. ETD is relatively simple and requires limited input
data, and yet it accounts for the predominant hydrolog-
ic and biochemical processes of the ecosystem.

The ability to predict the biological effect of complex
waste mixtures from chemical characterization data
was examined by comparing observed mortality to that
predicted by a mathematical additivity model with liter-
ature LD50 values for the chemicals identified in the
mixtures. Male F344 rats were exposed to one of ten
samples of complex industrial waste by gavage. Seven
of the ten waste samples caused death within 24 hours
of administration at dosages ranging from 1 to 5 ml/kg
body weight. Two of the seven lethal waste samples
produced 100% mortality at a dosage of 2.5 ml/kg; an-
other two waste samples produced 100% mortality at
5 ml/kg. The partial chemical analysis, although pro-
viding more extensive information on chemical compo-
sition than might normally be available for most com-
plex waste mixtures, was not sufficient to distinguish
lethal from nonlethal waste samples or to indicate
lethal potency.

A watershed acidification model for two New York
state lakes was verified by simulating an additional
year of field data that was excluded during the calibra-
tion period. The findings confirmed calibration and indi-
cated that the most sensitive physicochemical and bio-
chemical processes were chemical weathering, ion ex-
change, sulfate reduction by lake sediments, and sul-
fate adsorption by the terrestrial compartments. Long-
term simulations showed that both lakes will reach
steady state after a change in loading in fewer than 10
years. It was determined that 25 to 50% of the ex-
changeable bases in the upper soil will be depleted in
the next 50 years without chemical weathering to re-
supply the base exchange complex. The sulfate sorp-
tion mechanism is the only one that could delay water-
shed response after a change in loading. Some alka-
linity in one lake could be recovered if acid deposition
was decreased by a factor of two. The other would
remain alkaline even with twice as much acid deposi-
tion; however, in spring snowmelt events, lakes would
become more acidic.

Proposed is a nonlinear filtering approach to recursive
parameter estimation of conceptual watershed re-
sponse models in state-space form. The conceptual
model state is augmented by the vector of free param-
eters which are to be estimated from input-output data,
and the extended Kalman filter is used to recursively
estimate and predict the augmented state. The aug-
mented model noise covariance is parameterized as
the sum of two components: one due to errors in the
augmented model input and another due to errors in
the specification of augmented model constants that
were estimated from other than input-output data.
These components depend on the sensitivity of the
augmented model to input and uncertain constants.
Such a novel parameterization allows for non-station-
ary model noise statistics that are consistent with the
dynamics of watershed response as they are de-
scribed by the conceptual watershed response model.
Prior information regarding uncertainty in input and un-
certain constants in the form of degree-of-belief esti-
mates of hydrologists can be used directly within the
proposed formulation. Even though model structure
errors are not explicitly parameterized in the present
formulation, such errors can be identified through the
examination of the one-step ahead predicted normal-
ized residuals and the parameter traces during conver-
gence. The formulation is exemplified by the estima-
tion of the parameters of a conceptual hydrologic
model with data from the 2.1-sq km watershed of
Woods Lake located in the Adirondack Mountains of
New York. (Copyright (c) 1989 by the American Geo-

removal and venting of volatile organic compounds
(VOCs), such as TCE, from the subsurface soil without
excavation. The demonstration site was a property of
an operating machine shop in Groveland, MA. The site
was contaminated with VOCs, mainly TCE, which had
been used as a degreasing solvent. The Terra Vac

An assessment of the importance of input uncertainty
in long-term predictions of lake acidification is present-
ed. Mathematical models that simulate the behavior of
hydrologic catchments under acid deposition require
input data of precipitation, temperature, and deposition
chemistry. In long-term studies of lake acidification it is
necessary to hypothesize a scenario of future input to
the mathematical models. The present study indicates
that uncertainty in precipitation amount and acid con-
centrations can be very important in the characteriza-
tion of future lake alkalinity levels. It also suggests that
the natural day-to-day variability present in precipita-
tion and other weather variables significantly affects
long-term predictions of lake alkalinity in watersheds
with short response time, even more than weta nd dry

The sensitivity of human bronchial epithelial cells to in-
duction of micronuclei was determined in cultures de-
rived from different donors. Two direct-acting carcino-
gens, (+ or -)-7,8 -dihydroxy-9,10-epoxy-7,8,9,10- te-
trahydrobenzo (a)- pyrene (BPDE) and N-methyl-N'-
nitro-N-nitrosoguanidine (MNNG) were used to induce
micronuclei. Both agents increased the incidence of
micronuclei in a concentration-dependent fashion,
even at concentrations which did not produce cytotoxi-
crty. Cytokinesis was blocked with cytochalasin B so
that micronuclei were counted only in binucleate cells,
thereby decreasing the total number of cells that need
to be examined and also eliminating variations due to
possible differences in cell growth rates. The results
demonstrate the potential usefulness of the micronu-
cleus assay as a sensitive measure of genetic damage
in human epithelial cells. (Copyright (c) 1990 Perga-

Samples were collected during the winter of 1984-
1985 in the cities of Albuquerque, New Mexico and Ra-
leigh, North Carolina as part of a US Environmental
Agency study to evaluate methods to determine the
emission sources contributing to the mutagenic prop-
erties of extractable organic matter (EOM) present in
fine particles. Data derived from the analysis of the
composition of these fine particles served as input to a
multi-linear regression (MLR) model used to calculate
the relative contribution of wood burning and motor ve-
hicle sources to mutagenic activity observed in the ex-
tractable organic matter. At both sites the mutagenic
potency of EOM was found to be greater (3-5 times)
for mobile sources when compared to wood smoke ex-
tractable organics. Carbon-14 measurements which
give a direct determination of the amount of EOM that
originated from wood burning were in close agreement
with the source apportionment results derived from the
MLR model. (Copyright (c) 1990 Princeton Scientific

A quantitative theory has been developed to predict
coupled energy and mass transport phenomena
during inhalation of hydroscopic aerosol-laden air. It is
shown that hygroscopic particle-induced vapor scav-
enging will influence temperature and relative humidity
patterns within the respiratory system. Consequently,
particle growth kinetics will depend on its number con-
centration. Monodisperse hygroscopic aerosol will
become polydisperse and stratified, which may subse-
quently affect the deposition probabilities. (Copyright

A theoretical model of the simultaneous action of iner-
tial impaction and gravitational forces on a particle
moving in three dimensional circular bends is present-
ed. Deposition efficiencies are computed for three dif-
ferent idealized flow patterns: (1) uniform; (2) radially-
dependent, or rotational; and (3) parabolic. The bend
is in a vertical plane, the inclusive angle of the bend is
a variable, and its inlet can be at any angle of align-
ment to the horizontal. The results of these new simu-
lations are compared with available experimental data
and theoretical computations. The differential distribu-
tions of deposition along the length of the tubes are
examined. The relative contributions of the inertial im-
paction and sedimentation mechanisms to total (i.e.,
simultaneous) deposition are studied. The applicability
of simple pipe bend models, and their appropriate
limits, are examined for the deposition of aerosols in
human tracheobronchial bifurcations. The conceptual
model is further developed for the case in which an
airway bifurcation is characterized as a contiguous
system of straight and bent tubes. The results of differ-
ent bifurcation simulations are compared with each
other and laboratory data published in the open litera-
ture. (Copyright (c) 1990 Elsevier Science Publishing

Previous studies demonstrate that gonadotroph re-
sponsiveness to GnRH, GnRH binding, and the appar-
ent number of GnRH receptors are all increased by 17
beta-estradiol (E) or inhibin (IN) in ovine pituitary cul-
tures. Progesterone attenuates these effects. To ex-
plore differences between the effects of IN and E on
GnRH binding, a detailed time-course was performed.
The results indicate that after 48 h IN had a greater
effect on binding of a GnRH agonist (5-fold increase)
than E (3-fold increase), but was slower to act initially.
A combined treatment of IN and E gave a partially ad-
ditive effect at 48 h (6.5-fold increase). The mecha-
nism of receptor regulation in this system is not known,
but could involve synthesis, recycling, or modification
of GnRH receptors. To investigate the contribution of
altered receptor biosynthesis to the regulation of re-
ceptor levels, a functional Xenopus oocyte-based
assay for GnRH receptor mRNA activity was em-
ployed. After 48 h of treatment, IN or E each led to a 7
to 8-fold increase in GnRH receptor mRNA activity.
Treatment with both hormones led to a 19-fold in-
crease. The increase in mRNA activity induced by
either hormone was greatly attenuated by progester-
one. (Copyright (c) 1990 by The Endocrine Society.)

PIRLA II (Paleoecological Investigation of Recent Lake
Acidification) is the first paleolimnological study de-
signed to make statistically based regional population
estimates of lake acidification. It is also the first project
in which only tops and bottoms of cores are analyzed
so that a large number of lakes can be studied. The
PIRLA II project consists of several components that
are designed to address specific questions and are in-
tegrally related to several other projects. PIRLA II
builds on the foundation laid by PIRLA I; together they
make up one of the largest paleolimnological projects
in terms of number of lakes investigated (over 120
lakes analyzed stratigraphically). PIRLA has made and
will continue to make important contributions to the un-
derstanding of lake acidification and to the develop-
ment of the field of paleolimnology. (Copyright (c) 1990

A first-order second-moment uncertainty analysis has
been applied to two lakes in the Adirondack Park, New
York, to assess the long-term response of lakes to
acid deposition. Uncertainty due to parameter error
and initial condition error was considered. Because the
enhanced trickle-down (ETD) model is calibrated with
only 3 years of field data and is used to simulate a 50-
year period, the uncertainty In the lake alkalinity predic-
tion is relatively large. When a best estimate of param-
eter uncertainty is used, the annual average alkalinity
is predicted to be -11 + or - 28 mteroeq/L for Lake
Woods and 142 + or -139 mlcroeq/L for Lake Pan-
ther after 50 years. Hydrologlc parameters and chemi-
cal weathering rate constants contributed most to the
uncertainty of the simulations. Results indicate that the

Development of water stress in leaves of mature Quer-
cus rubra L caused a marked midday depression in
photosynthesis (A) and transpiration (E). At external
CO2 partial pressures of 100-110 Pa, a constant tem-
perature of 30 C and a constant photosynthetic photon
flux density of about 1000 micromol/sq m/s, A was 8
micromol/sq m at low leaf water potentials (-1.5 to -2.0
MPa), whereas it was 20 micromol/sq m/s in non-
stressed leaves (-1.0 ,Pa). At lower external CO2 par-
tial pressures, the effect of low leaf water potential on
A was less. The midday depression in gas exchange
was relieved by an overnight rain of 2.5 cm. No differ-
ence in carboxylation efficiency or CO2 compensation
point was found between leaves before and after rain.
The relationship between A and E was linear for a
given external CO2 partial pressure, but the slope
varied with CO2 concentration. Modification of the
model of stomatal response proposed by Ball et al.
(1987) produced a linear relationship between leaf
conductance and a factor incorporating A, relative hu-
midity, and OO2. (Copyright (c) 1990 Heron Publishing

The survival of genetically altered Pseudomonas
putida strains harboring an inducible plasmid, pR0101,
or a constitutive plasmid, pR0103, was compared.
These plasmids encode for the degradation of 2,4-
dichlorophenoxyacetate (TFD) to 2-chloromaleylace-
tate, and the maintenance of either plasmid did not
alter survival of P. putida PPO301(pRO101) or
PPO301(pRO103) in an unamended agricultural soil.
Moreover, in TFD-amended soil, survival of PPO301,
PPO301 (pRO101), and PPO301 (pRO103) was statisti-
cally the same after 50 days. Reapplication of TFD to
soil 50 days after the original application did not
change the numbers of PPO301(pRO101) or
PPO301(pRO103), which cannot use TFD as a sole
source of carbon. However, a mutant strain,
PPO301KS(pRO101), which is able to use TFD as a
sole source of carbon, was stimulated by the second
addition of TFD:PPO301KS(pRO101) cfu/g soil in-
creased by greater than 20-fold. Although the micro-
biota indigenous to the study soil was capable of de-
grading TFD, the addition of plasmid-bearing PPO301
had a dramatic effect on TFD degradation. In a parallel
study, Raphanus sativus (radish) seeds failed to germi-
nate in uninoculated and PPO301 -inoculated soil
amended with 500 ppm TFD. Seed germination was 53
and 80% in soils inoculated with PPO301(pRO101)
and PPO301(pRO103), respectively (P> 0.001). How-
ever, the difference in the rate of TFD degradation be-
tween the native soil and soil inoculated with plasmid-
bearing P.putida was probably related to the relatively
high inoculum density of P.putida strains (10 to the
eighth power cfu) and the relatively low population
density of TFD metabolizers indigenous to the soil.

Design streamflows are frequently used in water qual-
ity studies to provide adequate protection against pol-
lutant exposure periods of a given duration. By analyz-
ing the effect that simple streamflow dilution has on x-
day average exposure levels of a pollutant, it appears
that the x-day harmonic mean flow is a more meaning-
ful statistic to use in computing design flows than is the
customary arithmetic mean flow. The significance of
the result was examined by computing design flows for
sixty rivers throughout the country. For 7- and 30-day
average annual low flows the impact was minimal.
Substantial differences were found for the overall
mean daily flow-a design flow suggested for use with
water quality criteria based on protecting human health
against lifetime exposures. The overall harmonic mean
daily flow is typically 20 to 60 percent as large as the
arithmetic mean daily flow. For ungaged streams it can
be estimated from estimates of the arithmetic mean
flow and the 7-day, 10-year low flow by regional re-
gression analysis.

To produce environmental particles fortified with a po-
lycyclic aromatic hydrocarbon (PAH) for toxicology
studies, an experimental apparatus was devised for
deposition of the desired chemical species onto parti-
cles in a controlled and reproducible manner. The
technique utilized consists of dispersion of the parti-
cles on a gaseous stream at a controlled rate, thermal
vaporization of a solution of PAH, delivery of the vapor-
ized PAH into the aerosol of particles at a controlled
rate, subsequent condensation of the PAH onto the
particles, and final recovery of the coated particles.
The effectiveness of this approach wcs demonstrated
by vapor-coating a 14C-labeled PAH (1-nitro(14Q-
pyrene) onto diesel engine exhaust particles that had
previously been collected by tunnel dilution sampling
techniques. Using the 14C label as a tracer, the coated
particles were characterized with respect to degree of
coating, integrity of particle structure and absence of
chemical decomposition of the coating substrate. The
study demonstrates that the described method pro-
vides a controllable means for depositing a substance
uniformly and with a high coating efficiency onto aero-
solized particles. The technique was also used to
vapor-coat benzo(a)pyrene onto diesel engine exhaust
and unban ambient air paniculate matter, and 2-nitro-
fluoranthene onto unban ambient air paniculate matter.
Coating efficiencies of about 400 micrograms/g panic-
ulate matter were routinely obtained on a single coat-
ing run, and up to 1200 micrograms/g (1200 ppm)
were achieved after a second pass through the proc-
ess. The coated particles were subsequently utilized in
biological fate, distribution and metabolism studies.

Systems. In the first phase of this program, 16 labora-
tories submitted data on the genetic effects of EMS
evaluated in three bioassays; i.e., Vicia faba root hair,
Tradescantia micronuclei, and Arabidopsis embryo
assays. In general, all participating laboratories ob-
tained positive results with EMS, but some laboratories
yielded data that showed significantly higher levels of
spontaneous mutagenic effects, perhaps due to con-
taminants in the water or air. Research is in progress
on evaluating the genotoxic effects of four additional
chemicals. The first phase of this project is scheduled
to be completed in December 1990. Upon the evalua-
tion of the results of the first phase, recommendations
will be made regarding the initiation of the second
phase. (Copyright (c) 1991 Elsevier Science Publish-

Synaptonemal complexes (SCs) reveal mutagen-in-

study was aimed at characterizing relationships be-
tween SC and metaphase I chromosome damage fol-
lowing radiation exposure at various stages of sper-
matogenesis. Male mice were irradiated with doses of
0, 2, or 4 Gy, and spermatocytes were harvested at
times consistent with earlier exposures as spermato-
gonial stem cells, preleptotene cells (premeiotic DNA
synthesis), or meiotic prophase cells. After stem-cell
exposure, twice as many rearrangements were ob-
served in SCs as in metaphase I chromosomes. Irra-
diation during premeiotic DNA synthesis resulted in
dose-related increases in SC breakage and rearrange-
ments (including novel forms) and in metaphase chro-
mosomal aberrations. Following prophase exposure,
various types and levels of SC and metaphase
damage were observed. Irradiation of zygotene cells

The microbial ecology of pristine and contaminated
ground water at a chemical waste disposal site was in-
vestigated. Recently, it was determined that ground
water downslope from the disposal site contained ele-
vated levels of toxic pollutants, including benzene, tol-
uene, xylene and methylene chloride, as well as iron
and manganese. Microbial mineralization and uptake
of radio-labeled glucose and amirto acids indicated a
metabolically active microflora in both pristine (ups-
lope from the contamination) and contaminated
groundwater samples collected from monitoring wells
at the site. However, microbial uptake and mineraliza-
tion of glucose and amino acids were up to fourfold
slower in the contaminated well water than in the con-
trol well. Rates of mineralization and uptake of toluene
were easily measurable in water from the contaminat-
ed but were negligible in water from the pristine well,
suggesting that the subsurface microflora in the con-
taminated region had adapted to degrade toluene. Ad-
ditions of the inorganic nutrients N, K, and P enhanced
toluene mineralization in water from the contaminated
well, with the addition of K and P enhancing mineral-
ization twofold. The addition of these inorganic nutri-
ents, therefore, presents an opportunity for biorestora-
tion of the site. An increase in the incubation tempera-
ture also enhanced toluene mineralization; however
manipulation of pH and dissolved oxygen concentra-
tion had no measureable effects.

A model describing passive accumulation of organic
chemicals from the aqueous environment and con-
taminated food in fish is developed. The model consid-
ers both biological attributes of the fish and physico-
chemical properties of the chemical that determines
diffusive exchange across gill membranes and intesti-
nal mucosa. Important biological characteristics ad-
dressed by the model are the fish's gill morphometry,
feeding and growth rate, and fractional aqueous, lipid,
and nonlipid organic composition. Relevant physico-
chemical properties are the chemical's molar volume
and noctanol/water partition coefficient (Kow), which
are used to estimate the chemical's aqueous diffusivity
and partitioning to the fish's lipid and nonlipid organic
fractions, respectively. The model is used to describe
and to analyze the bioaccumulation of polychlorinated
biprtenyls (PCBs) in Lake Ontario alewife (Alosa pseu-
doharengus), coho salmon (Oncorhynchus kisutch),
rainbow trout (Oncorhynchus mykiss), brown trout

The article focuses on a preliminary cost analysis that
compares liquid-phase granular activated carbon
(GAC) treatment with packed-tower aeration (PTA)
treatment, with and without air emissions control. The
sensitivity of cost to design and operating variables is
also discussed. For most of the contaminants exam-

BioTrol's pilot scale, fixed-film biological system was
evaluated, under the EPA's SITE program, for its effec-
tiveness at removing pentachlorophenol from ground-
water. The demonstration was performed in the
summer of 1989 at a wood preserving site in New
Brighton, Minnesota. The system employs indigenous
microorganisms amended with a specific pentachloro-
phenol-degrading bacterium. Groundwater from a well
on the site was fed to the system at 1, 3, and 5 gpm
with no pretreatment other than pH adjustment, nutri-
ent addition, and temperature control. Each flowrate
was maintained for about two weeks while samples
were collected for extensive analyses. At 5 gpm, the
system was capable of eliminating about 96 percent of
the pentachlorophenol in the groundwater and produc-
ing effluent with pentachlorophenol concentrations to
about 1 ppm. At the lower flows (1 and 3 gpm) removal
was higher (about 99 percent) and effluent pentachlor-
ophenol concentrations were well below 0.5 ppm. The
system consistently produced a completely nontoxic
effluent at all three flowrates. Review of other data
provided by BioTrol indicates that the process is also
effective on other hydrocarbons, including solvents
and fuels. The system appears to be a compact and
cost-effective treatment for contaminated
wastewaters requiring minimal operating attention
once acclimated. (Copyright (c) 1991--Air & Waste

A study was conducted on treating a simulated leach-
ate that contained high concentrations of ammonia-ni-
trogen ranging between 20 and 1000 mg/L. A pilot
sized rotating biological contractor (RBC) was used to
treat a surrogate leachate composed of primary efflu-
ent that was adjusted with glucose and ammonium
chloride to achieve various concentrations of dis-
solved organic carbon and ammonia-nitrogen. Experi-
ments were conducted to determine: The rate of am-
monia conversion; The drop in pH at high ammonia
concentrations; The effect of low pH on ammonia con-
version; The effect of high ammonia levels (1000 mg/
L) on ammonia conversion, and The effect of tempera-
ture on the reaction rate constant. The results from
these experiments and the applicability of a RBC to
treat leachates containing high concentrations of am-
monia-nitrogen are reported.

Determining the fate and survival of genetically-engi-
neered microorganisms released into the environment
requires the development and application of accurate
and practical methods of detection and enumeration.
Several experiments were performed to examine
quantitative recovery methods that are commonly
used or that have potential applications. In these ex-
periments, Erwinia herbicola and Enterobacter cloa-
cae were applied in greenhouses to Blue Lake bush
beans (Phaseolus vulgaris) and Cayuse oats (Avena
saliva). Sampling indicated that the variance in bacte-
rial counts among leaves increased over time and that
this increase caused an overestimation of the mean
population size by bulk leaf samples relative to single
leaf samples. An increase in the number of leaves in a
bulk sample, above a minimum number, did not signifi-
cantly reduce the variance between samples. Experi-
ments evaluating recovery methods demonstrated
that recovery of bacteria from leaves was significantly
better with stomacher blending, than with blending,
sonication, or washing and that the recovery efficiency
was constant over a range of sample inoculum densi-
ties. Delayed processing of leaf samples, by storage in
a freezer, did not significantly lower survival and recov-
ery of microorganisms when storage was short term
and leaves were not stored in buffer. The drop plate
technique for enumeration of bacteria did not signifi-
cantly differ from the spread plate method. Results of

Widespread use of trichloroethylene (TCE) in the U.S.
has resulted in its frequent detection in soil and
groundwater. TCE can become a health hazard after
being processed in the human liven or reductive deha-
togenatton in the environment may result in production
of vinyl chloride, a known carcinogen. This has gener-
ated a high degree of interest in efficient and cost-effi-
cient technologies that can be used to remediate soil
and groundwater contaminated with TCE. The purpose
of the paper is to present and discuss relevant prtys-
icochemical properties and reactive mechanisms of
TCE, and to delineate and discuss promising remedi-
ation methodologies that have been proposed and/or
demonstrated for restoring contaminated subsurface
environments. The information in the article has been

Numerical site-specific chemical and biological criteria
were established to assess the impact of a pilot dredg-
ing project on water quality at the New Bedford Harbor,
Massachusetts, USA, Superfund site. Because most
existing chemical concentrations in the water column
and indigenous biota exceeded federal and state
water quality limits, the derivation of site-specific crite-
ria was required. Prior to any operational phases of the
project (i.e., dike construction, dredging), criteria
values were developed from background concentra-
tions of PCBs and metals in water and biota, as well as
for the toxic effects of water quality on the biota.
During each operational phase of the project water
samples were collected, analyzed within 16 h, and the
data supplied to a management committee in order to
assess the environmental impact of the previous days
operation. The ambient unfiltered water concentration
of PCBs and metals were the only chemical or biologi-
cal criteria exceeded. Modification of the next days'
operations resulted in a return of these concentrations
to background levels. The combined use of site-specif-
ic criteria and a real-time decision making manage-
ment process allowed for successful completion of the
project with a minimal effect on water quality. (Copy-

Quantitative health risk assessments have been per-
formed for a number of proposed municipal waste
combustor (MWC) facilities over the past several
years. The article presents the results of a compara-
tive analysis of a total of 21 risk assessments, focusing
on seven of the most comprehensive methodologies.
The analysis concentrates on stack emissions of non-
criteria pollutants and is comparative rather than criti-
cal in nature. Overall, the risk assessment methodolo-
gies used were similar whereas the assumptions and
input values used varied from study to study. Some of
the variability results directly from differences in site-
specific characteristics, but much of it is due to ab-
sence of data, lack of field validation, lack of specific
guidelines from regulatory agencies, and reliance on
professional judgment. The results indicate that carci-
nogenic risks are more significant than chronic non-
carcinogenic risks. In most instances polychlorodiben-
zodioxins, polychlorpdibenzofurans, and cadmium
contribute more significantly to the total carcinogenic
risk from MWC stack emissions than other contami-
nants. In addition, the contribution to total risk of all in-
direct routes of exposure (ingestion and dermal con-
tact) exceeds that of the direct inhalation route for
most studies reviewed. (Copyright (c) 1991-Air &

A two-dimensional mathematical model for simulating
the transport and fate of organic chemicals in a labora-
tory scale, single layer aquifer is presented. The aqui-
fer can be nonhomogeneous and anisotropic with re-
spect to its fluid flow properties. The physical model
has open inlet and outlet ends and is bounded by im-
permeable walls on all sides. Fully penetrating injec-
tion and/or extraction wells can be placed anywhere in
the flow field. The inlet and outlet boundaries have
user prescribed hydraulic pressure fields. The steady
state hydraulic pressure field is obtained first by using
the two-dimensional Darcy flow law and the continuity
equation. The chemical transport and fate equation is
then solved in terms of user stipulated initial and
boundary conditions. The model accounts for the
major physical processes of storage, dispersion, and
advection, and also can account for linear equilibrium
sorption, first-order loss processes, microbial denitrifi-
catkm, irreversible sorption and/or dissolution into the
organic phase, metabolism in the sorbed state, and
first order loss in the sorbed state.

Section 405 of the Clean Water Act requires the U.S.
Environmental Protection Agency to develop and
issue regulations that identify: (1) uses for sludge in-
cluding disposal; (2) specific factors (including costs)
to be taken into account in determining the measures
and practices applicable for each use or disposal; and
(3) concentrations of pollutants that interfere with each
use or disposal. To comply with the mandate, the U.S.
EPA has embarked on a program to develop four
major technical regulations: Land application, includ-
ing distribution and marketing; landfilling; incineration
and surface disposal. The development of these tech-
nical regulations requires a consideration of patho-
gens as well as chemical constituents of sludge. Public
concern related to the reuse and disposal of municipal
sludge often focuses on the issue of pathogenic orga-
nisms. The purpose of the report is to use the patho-
gens methodology. Pathogen Risk Assessment for
Land Application of Municipal Sludge, to develop a
preliminary assessment of risk to human health posed
by parasites in municipal sewage sludge applied to
land as fertilizer or soil conditioner. The preliminary risk
assessment includes a description of the most critical
data gaps that must be filled before development of a
definitive risk assessment and recommends research
priorities.

A major goal of the Direct/Delayed Response Project
(DDRP), a project within the U.S. Environmental Pro-
tection Agency's (EPA) Aquatic Effects Research Pro-
gram (AERP) is to project potential changes in surface
water chemistry in lakes in the northeastern U.S. and
streams in the Mid-Appalachians and southeastern
U.S., over the next 50 years as a function of current
and alternative levels of acidic deposition. The DDRP
projection are based on various types of simulations
models that predict surface water and soil chemistry.
All models- statistical, empirical, mechanistic, logical
or others - represent a simplification or abstraction of
the real world. A major question associated with the
application of an model is how to prepare subset, and
aggregate, or lump, data so that they will represent the
processes and system being simulated. The models
used in the DDRP require physical and chemical data
on watershed soils as part of the model inputs. In con-
junction with the DDRP, soil surveys were conducted
in selected watersheds in each of the three regions.
The document describes and discusses the approach-
es used in the DDRP for aggregating soil chemical and
physical data for use in the various DDRP analyses.

The attention of environmental decision makers is in-
creasingly being focused on the movement of pollut-
ants into ground water. Of particular importance is the
transport and speciation of metals. The MINTEQA2
model is a versatile, quantitative tool for predicting the
equilibrium behavior of metals in a variety of chemical
environments. MINTEQA2 is a gepchemical speciation
model capable of computing equilibria among the dis-
solved, adsorbed, solid, and gas phases in an environ-
mental setting. MINTEQA2 includes an extensive da-
tabase of reliable thermodynamic data that is also ac-
cessible to PRODEFA2, an interactive program de-
signed to be executed prior to MINTEQA2 for the pur-
pose of creating the required MINTEQA2 input file.
The report describes how to use the MINTEQA2
model. The chemical and mathematical structure of
MINTEQA2 and the structure of the database files also
are described. The use of both PRODEFA2 and MIN-
TEQA2 are illustrated through the presentation of an

PC BEEPOP is a computer model that simulates honey
bee (Apis mellifera L.) colony population dynamics.
The model consists of a system of interdependent ele-
ments, including colony condition, environmental vari-
ability, colony energetics, and contaminant exposure.
It includes a mortality module (BEEKILL) and a chemi-
cal-toxicity data base (BEETOX). PC BEEPOP builds
upon BEEPOP, a mainframe-based colony dynamics
model. PC BEEPOP is a research and assessment tool
for assessing the responses of honey bees as ecologi-
cal indicators of environmental condition. The combi-
nation of BEETOX, BEEKILL, and BEEPOP provides a
means of examining the influence of xenobiotics on
colony population dynamics, including energetics, and
not just adult or brood mortality. The authors simula-
tions indicate that PC BEEPOP is capable of making
plausible predictions of colony structure, size, and en-
ergetics. In addition, the model can help identify proba-
ble causes of colony growth and decline.

lutant formation and emission. Test results indicated
two sources of PCDD/PCDF formation: the combustor
upstream of the mixing chamber and the ESP. PCDD/
PCDF leaving the combustor appears to be associated
predominantly with entrained particulate matter (PM)
with particles larger than 10 micrometers. Increases in
PCDD/PCDF concentrations across the ESP were
found at lower temperatures (148 C) than previously
reported. Indicated PCDD/PCDF formation rates in the
ESP were highly dependent on ESP inlet temperature.

The paper describes an approach for analyzing the
impact of sources of indoor air quality (IAQ) based on
chamber studies, modeling, and test house studies.
Source emission factors are developed in chamber
studies. The emission factors are used in an IAQ
model that incorporates room-to-room air movement,
sinks, and air exchange with the outdoors to predict
indoor air pollution concentrations from the source.
Test house experiments are used to verify the model
and identify unmodeled factors. The agreement be-
tween model predictions based on chamber emission
factors and test house data is excellent.

Presented at the Solid Waste Association Meeting of
North America's Annual International Landfill Gas
Symposium (14th), San Diego, CA., March 26,1991.
The paper discusses a portion of EPA's global climate
change program, a program plan for methane emis-
sions from landfills and other waste disposal facilities.
In response to concerns about global climate change,
the U.S. EPA's Office of Research and Development
(ORD) has initiated an emissions and mitigation pro-
gram. ORD's Air and Energy Engineering Research
Laboratory (AEERL) has begun research on green-
house gas emission estimation, biomass and methane
utilization, tropospheric ozone, and evaluation of po-
tential mitigation opportunities for emissions contribut-
ing to global climate change. The emissions program
has begun to identify and quantify emission sources of
greenhouse gases for anthropogenic sources includ-
ing landfills, coal mines, natural gas production/distri-
bution, cookstoves, and biomass burning. Develop-
ment of enhanced emission estimates will improve the
understanding of atmospheric chemistry and feedback
effects, target mitigation opportunities, and ensure
cost-effective mitigation strategies. The focus of the
paper is on AEERL's research efforts on global landfill
methane.

National Lab., Upton, NY. Dept. of Applied Science,

The paper discusses the production of methanol and
carbon from biomass and fossil fuels, utilizing the Hy-
drocarbon process. The process has the potential to
minimize dependence on imported fuels for the trans-
portation and utility sectors by increasing the yield and
reducing the cost of methanol obtainable from domes-
tic natural gas. This is accomplished by utilizing bio-
mass as a co-feedstock in an energy-efficient, three-
step conversion. An equally important product of the
process is a carbon that is free of ash, sulfur, and nitro-
gen. The carbon can be used as a clean industrial and
utility fuel to eliminate the pollution associated with the
use of coal and reduce the cost of emission controls.
The possibility of global climate change implies that
CO2 emissions should be taken into account when as-
sessing options for producing future alternative fuels.
From mis, as well as the other environmental stand-
points, Hydrocarb offers advantages.

In the US, lead occurs primarily as a corrosion by-prod-
uct in public drinking water supplies. That is, its source
is the corrosive action of the water upon the materials
used in the water distribution system and private
plumbing. Historically, drinking water has not been a
major source of lead exposure for most Americans.
However, as other sources of lead exposure continue
to decline in this country, particularly decreased air-
borne lead from reduced use of leaded gasoline and
decreased dietary lead, the relative contribution of
drinking water as an exposure source has increased.
This has occurred simultaneously with increasing evi-
dence that lead's health effects occur at lower expo-
sure levels, levels previously thought to be 'safe'.
There is, however, no single, available data base for
assessing exposure to lead in drinking water. In the ar-
ticle, the authors use a variety of data sources to de-
velop a profile of lead levels in US public drinking water
supplies, providing some upper and lower bound esti-
mates of likely exposures as well as identifying some
risk factors.

Corrosion control has been known both as a cost-
saving and as a health protection method for almost a
century. But, surprisingly, relatively little field and labo-
ratory research has been conducted contrasting alter-
native approaches or presenting results before and
after such water treatment programs were implement-
ed. A thorough review of chemical treatment strategies
and engineering technologies, a presentation and
analysis of field trials, and a summary of costs incurred
for various treatment approaches is needed. Unfortu-
nately, the data are far from complete. However, all
water systems across the country, public and private,
are being required now to address both the health
risks of drinking water contaminated by corrosion by-
products and the cost-reducing potential of corrosion
treatment. The paper presents a snapshot summary of
the state of current knowledge about control of internal
corrosion, focussing particularly on lead and copper
corrosion.

Three commercial polyphosphate-containing water
treatment products were evaluated for their ability to
affect lead solubility in drinking water. A 'Competing-
Ligand Spectrophotometry' Technique was used to
characterize Pb(2+) complexation at 20 degrees C in
ionic strength of 0.1, pH = 8, and calcium concentra-
tion of .001 mol/L The pH was buffered by HEPES,
and the colorimetric reagent was 4-(2-pyridylazo)-re-
sourcinol (PAR). Results were also compared to a
DPASV method. The data was fit by a 2- ligand model.
The experiments suggested a significant ability to en-
hance lead solubility by complexation at the pH and

The article presents the development of model equa-
tions for describing the fate of viral infectivity in envi-
ronmental samples. Most of the models were based
upon the use of a two-step linear regression approach.
The first step employs regression of log base 10 trans-
formed viral liter ratios from various sampling dates as
the dependent variable versus the length of time that
the viruses were incubated in the test material as the
independent variable. The slope values derived from
this first step of the regression technique are then
used as the dependent variable in the second step of
the analysis, when they are linearly regressed against
either a single independent variable such as soil mois-
ture level or incubation temperature, or against a set of
independent variables in a multiple regression. A varie-
ty of examples based upon experimental data were
used to demonstrate the application and benefits of
this two-step regression technique.

The subject of the paper is the experience with a novel
and field-proven method for the enhanced control of
transient emissions from rotary kiln incinerators using
oxygen enrichment. When high-BTU content wastes
are fed into rotary kiln incinerators in an intermittent
mode (typical of ram feed systems), the transient com-
bustion behavior of these materials creates unsteady
releases of combustible gases which may momentarily
deplete the oxygen content of kiln gases. These tem-
porary oxygen-deficient conditions could cause the re-
lease of products of incomplete combustion (PICs).
Release of PICs from incinerators has raised public
concern and has been the subject of research projects
sponsored by the EPA. The enhanced control of tran-
sient emissions was demonstrated by the field oper-
ation of the EPA Mobile Incineration System (MIS) at
the Denney Farm Superfund Site in McDowell, Missou-
ri. During the field operation of the MIS, large quantities
of high-BTU content wastes were burned periodically.
These materials were ram-fed into the rotary kiln at a
frequency of about twice a minute. To respond to the
transient oxygen demand resulting from the burning of
these materials, a unique oxygen feedforward-feed-
back control logic was designed into the LINDE
Oxygen Combustion System (OCS) which was retro-
fitted into the MIS in 1987. After implementation of the
OCS, transient upset conditions were significantly re-
duced during the operation of the MIS. Low NOx emis-
sions were also achieved.

A series of pilot-scale incineration tests was performed
at EPA's Incineration Research Facility to evaluate the
thermal stability-based POHC incinerability ranking. In
the tests, mixtures of 12 POHCs with predicted inciner-
ability spanning the range of most to least difficult to in-
cinerate class were combined with a clay-based sor-
bent and batch-fed to the facility's pilot-scale rotary
kiln incinerator via a fiberpack drum ram feeder. Kiln
operating conditions were varied to include a baseline
operating condition, three modes of attempted inciner-
ation failure, and a worst case combination of the three
failure modes. Kiln exit POHC DREs were in the 99.99
percent range for the volatile POHCs for the baseline,
mixing failure (increased charge mass), and matrix fail-
ure (decreased feed H/C) tests. Semivolatile POHCs
were not detected in the kiln exit for these tests; corre-
sponding DREs were generally greater than 99.999
percent. The thermal failure (low kiln temperature) and
worst case (combination of thermal, mixing, and matrix
failure) tests resulted in substantially decreased kiln
exit POHC DREs. These ranged from 99 percent or
less for Freon 113 to greater than 99.999 percent for
the less stable-ranked semivolatile POHCs. General
agreement between relative kiln exit POHC ORE and
predicted incinerability class was observed.

Pub. in APCA Specialty Conference Proceedings 'Per-

of Hazardous Wastes', p60-70.
The paper describes the use of solidification/stabiliza-
tion (S/S) technology for treating hazardous waste. Al-
though it has been used for 20 or more years to treat
U.S. industrial waste, the banning of selected untreat-
ed waste to the land has resulted in an increased inter-
est in the technology. S/S involves the addition of
binders (e.g., portland cement, lime, fly ash, etc.) to the
waste to alter the waste form and decrease the mobili-
ty of the pollutants. Advantages and disadvantages of
S/S vary with the process, the binders, the waste, site
conditions and other factors. As an alternative treat-
ment technology, S/S best potential use is to treat
wastes that are banned from land disposal. However,
there are important factors which will affect the use of
S/S. These include waste characteristics, process
types, S/S waste treatment and management objec-
tives, regulatory requirements, and economics. These
and other specific factors must be carefully considered
to ensure acceptable S/S performance.

Basic research and monitoring of sludge utilization
programs have identified specific Pathways by which
potentially toxic constituents of sewage sludge can
reach and cause toxicity to livestock, humans, plants,
soil biota, wildlife, etc. In the process of preparing a
new regulation for land application of sewage sludge in
the US, a Pathway approach to risk assessment was
undertaken. Two Pathways were found to comprise
the greatest risk from persistent lipophilic organic com-
pounds such as RGBs: (1) direct ingestion of sludge by
children; and (2) adherence of sludge to forage/pas-
ture crops from surface application of fluid sludge, fol-
lowed by grazing and ingestion of sludge by livestock
used as human food. Each Pathway considers risk to
Most Exposed Individuals (MEIs) who have high expo-
sure to sludge. Because 1990 sewage sludges contain
very low levels of PCBs, the estimated risk level to
MEIs was less 0.0001, low sludge PCBs and low prob-
ability of simultaneously meeting all the constraints of
the MEI indicate that MEIs are at less 0.0000001 life-
time risk. The authors conclude that quantitative risk
assessment for potentially toxic constituents in
sewage sludge can be meaningfully conducted be-
cause research has provided transfer coefficients from
sludges and sludge-amended soils to plants and ani-
mals needed for many organic compounds.

Approximately 21 billion pounds of pesticides have
been applied to United States farmlands since 1964. In
agricultural regions, high pesticide concentrations
occur in surface and groundwaters because of spring
runoff or leaching. Because many of these compounds
pose health risks, the United States Environmental
Protection Agency (USEPA) has a mandate, under the
Safe Drinking Water Act Amendments of 1986, to reg-
ulate several of these compounds. Others will be un-
dergoing regulatory scrutiny because they are included
in EPA's First Drinking Water Priority List, as well as
the National Pesticide Survey. In an attempt to under-
stand possible compliance problems, an investigation
was conducted on river water containing Alachior, Al-
trazine, Cyanazine, Linuron, Metolachlor, Metribuzin,
and Simazine. The purpose of the study was to deter-
mine to what extent several treatment processes such
as reverse osmosis were able to remove pesticides
from the Sandusky River at the Tiffin, Ohio Water
Treatment Plant. In addition pilot scale studies were
conducted using several different types of polymeric
membranes to remove pesticides from spiked ground-
water.

The Safe Drinking Water Act (SDWA) and its Amend-
ments sets regulations applicable to all community
water systems that have 15 or more service connec-
tions and/or serve at least 25 people. At first glance,
this may appear most inclusive, but in reality there are
numerous private homeowners, non-community, and
transient populations potentially at risk to contaminat-
ed drinking water. In addition, the tens of thousands of
very small community systems (approximately 500
population served) currently regulated have little
chance of complying with the ever increasing number
of regulated contaminants or instituting Best Available
Technology (BAT). Their problems are well document-
ed as is the lack of resources to correct those prob-
lems. Therefore, the purpose of the paper is to provide
a practical overview to the 'little guy' attempting to pro-
vide safe drinking water. The overview will present the
advantages, disadvantages, and costs of several treat-
ment technologies focusing on those aspects of cost,
reliability, and ease of operation for those technologies
that make them more amenable to package plant and
Point-of-Use/Point-of-Entry (POU/POE) operation

Whenever dredged materials are disposed into the
ocean, the potential effects of the materials on human
health, fishery resources, and marine ecosystems may
range from being negligible or unmeasureable to im-
portant. Because these effects may differ greatly at
each dredged material extraction or disposal site, each
site must be evaluated on a case-by-case basis. In the
United States, the manual entitled Ecological Evalua-
tion of Proposed Discharge of Dredged Material into
Ocean Waters: Implementation Manual for Section
103 of Public Law 92.532 (Marine Protection, Re-
search, and Sanctuaries Act of 1972) (the 'Implemen-
tation Manual' or 'Green Book') was published in 1977
to give guidance on determining the potential biologi-
cal effects caused by dredging operations. The Green
Book provides detailed guidance on the conduct of the
required bioassays on the liquid, suspendEd particu-
late, and solid phases of a dredged material, in addi-
tion, guidance is given on how to conduct the bioas-
says and bioaccumulation tests. The U.S. Environmen-
tal Protection Agency (EPA) recently published a
manual that gives guidance on the appropriate length
of the bioaccumulation tests (i.e., 28 days), recom-
mended test speCles, and conduct of the tests. In the
past, the U.S. Food and Drug Administration's 'Action
Limits' and international fish and shellfish standards
have occasionally been used in the interpretation of
dredged material bioaccumulation data. Even though

equivalent, can exhibit a variety of responses when
challenged with the same initial total toxicant concen-
tration. Differences in realized actual exposure con-
centrations can result from differences in physical
morphology, water and sediment chemistry, and physi-
cal transport processes. Seasonal differences in cli-
matology and biological community structure also alter
ecosystem responses. Simulation models and com-
parative studies provide methods for extrapolation.

The National Acid Precipitation Program (NAPAP) Inte-
grated Assessment discussion of visibility, and its
more detailed supporting document State-of-Sci-
ence/Technoiogy (SOS/T) Report 24, have been re-
viewed with regard to completeness in their discussion
of visibility measurement methods, chemical analysis
procedures to determine the species responsible for
visibility impairment and methods to calculate light ex-
tinction b(sub ext) budgets. The supporting document,
SOS/T Report 24, contains citations and substantial
discussion and interpretation of past and ongoing re-
search and monitoring associated with visibility. While
both documents are a masterpiece in terms of compil-
ing abbreviated discussions, some aspects of the doc-
uments reflect the biases of the authors, as evidenced
by omissions of discussions related to visibility studies
performed by the U.S. Environmental Protection
Agency at Research Triangle Park, NC. The work by
the EPA group is of substantial significance in that im-
portant complex problems associated with uncertain-
ties in b(sub ext) budgets were addressed and meth-
odology developed to minimize or estimate the uncer-
tainties. The b(sub ext) budget protocols developed by
the EPA group should be incorporated into the model-
ing and methods interpretation sections. More empha-
sis should be given to the status of measurement tech-
nologies which support visibility assessments. In par-
ticular, the shortcomings of elemental carbon meas-
urements need to be emphasized.

A multiple linear regression receptor model has been
used to apportion ambient concentrations of fine parti-
cle extractable organic matter (EOM) and associated
mutagenicity (Salmonella typhimurium TA98 +S9),
measured in Boise ID during the 1986-1987 winter. Ex-
tensive (14)C measurements were also employed to
verify the accuracy of the wopdsmoke contribution es-
timate given by the regression approach. In general
the Boise results are found to be consistent with those
of earlier studies in Albuquerque NM and Raleigh NC,
with mutagenic potencies of about 1 and 3 revertants
per microgram of EOM for woodsmoke and mobile
source emissions, respectively. The measurements
were performed as part of the U.S. EPA's Integrated
Air Cancer Project.

The sector sampling approach for the determination of
the spatial contributions of volatile organic compounds
to the ambient air was employed at a Superfund site
under remediation. Two canister based sampling sys-
tems were deployed and whole air samples were col-
lected at the Shaver's Farm Superfund Site in north-
west Georgia near Chattanooga, Tennessee, while
chemical waste drums were excavated and repack-
aged. The method is based upon the collection of a
constant stream of air into one of two SUMMA pol-
ished canisters depending on wind direction; when the
wind comes towards the sampler from the suspected
emissions area, sample is routed into the 'IN' sector
canister, otherwise, sample is collected in the 'OUT'
sector canister. Upon analysis, the comparison be-
tween the IN and OUT sample results indicates com-
pounds that are emitted from the suspected source
area. Data from the week-long Shaver's Farm field
study are presented along, with a mathematical
method for interpretation.

Sick Building Syndrome may be caused in part by vola-
tile organic compounds (VOCs). One hypothesis is that
the total volatile organic concentration (TVOC), rather
than individual compounds, is a main factor in the syn-
drome. The TVOC level at which symptoms occur has
been estimated to be in the range of 1-2 mg/cum,
based on measurements employing GC-FID tech-
niques. Very few measured data are available to deter-
mine the frequency with which homes and buildings in
the United States may approach TVOC levels of this
magnitude. However, data on 12-hour average values
of individual VOCs from 750 homes and 10 buildings
were available from EPA's TEAM Studies (1981-88).
An initial study to determine the feasibility of obtaining
a TVOC value from stored GC/MS data showed that
TVOC estimated could be obtained with satisfactory
precision ((+ or -) 30-60%). Therefore TVOC values
were calculated from about 2700 personal, indoor, and
outdoor air samples collected in the TEAM Studies.

Polar volatile organic compounds were identified in the
headspace of 31 fragrance products such as per-
fumes, colognes and soaps. About 150 different
chemicals were identified in a semiquantitative fash-
ion, using two methods to analyze the headspace:
direct injection into a gas chromatograph and collec-
tion by an evacuated canister, each followed by GC-
MS analysis. The canister method displayed low re-
coveries for most of the 25 polar chemical standards
tested. However, reconstructed ion chromatograms
(RICs) from the canister showed good agreement with
RICs from the direct injection method except for some
high boiling point compounds. Canister samples col-

The US EPA studied the exposures of 175 residents of
Riverside, CA to inhalable particles (<10 micrometers
diameter) in the early fall of 1990. Participants were
probabilistically selected to represent most of the Riv-
erside nonsmoking population over the age of 10.
They wore a newly-designed personal monitor (4 Lpm
pump and filter) for two consecutive 12-hour periods
(day and night) to determine their exposure to PM-10.
Exposure to nicotine was also determined by a citric
acid treated filter. Indoor and outdoor samples were
collected concurrently at each home. Air exchange
rates were determined for each household for the day
and night periods. The response rate of the population
was about 50%, roughly comparable to previous
TEAM Studies. The personal and fixed particle moni-
tors showed excellent precision of about 4% RSD.

conventional gasolines and diesel fuels. The implica-
tions of the physical and chemical differences of these
fuels for motor vehicle design and emissions are dis-
cussed. Potential material compatibility concerns,
such as elastomer swelling and metal corrosion, and
safety concerns, such as fire hazard, flame luminosity,
and human tqxfcity are examined. A number of possi-
ble air quality impacts are examined including changes
in ozone, carbon monoxide, oxides of nitrogen, particu-
late matter, toxic compounds (benzene, aldehydes,
1,3-butadiene), and global climate 'greenhouse' gases
(carbon dioxide, methane, nitrous oxide).

The U.S. EPA recently completed a study of nqnoccu-
pational exposure to household pesticides. During that
study, house dust and yard soil were recognized to be
potential major sources of exposure for infants and
toddlers. Consequently, a pilot study was initiated in
the fall of 1990 to evaluate exposure methodology and
obtain preliminary comparative data on routes of expo-
sure for the susceptible population. Nine homes with
children aged six months to five years were selected
on the basis of pesticide use. House dust was collect-
ed using a newly-designed cyclone vacuum system.
Dislodgeable residues were collected from floors by
means of a polyurethane foam (PUF) roller weighted to
simulate a 9 kg child. Investigator's hand-presses and
child's hand rinses were performed for comparison to
the PUF roller. Soil and entry-way dirt samples were
collected and air was sampled at 12 cm and 75 cm
above the floor. All samples were analyzed for a list of
30 common household pesticides. Questionnaires
were administered to participants regarding pesticide
usage, child activities (including frequency of hand-to-
mouth contact), and dietary habits.

A protocol has been developed to enable source oper-
ators to comply with provisions of Title III of the Clean
Air Act Amendments of 1990 which allows certain ex-
emptions if reductions in emissions can be demon-
strated and validated source emission test methods
are not available. Essentially, the procedures consist
in determining the method's bias and precision, the
former by using known concentrations of analyte, and
the latter by means of collocated sampling trains. The
use of isotopically-labelled materials, comparisons
with a validated method, or analyte spiking are tech-
niques that may be employed. There is a requirement
tht the analyst use an EPA audit material. Equations
are given to calculate precision, to determine if bias is
statistically significant, and to calculate correction fac-
tors if applicable. The protocol disallows the use of test
methods having a bias greater than 30% or a precision
greater than 50% at the level of the applicable stand-
ard.

Wetlands have been a minor element in EPA's water
quality regulatory frame but their importance will
expand following their mandatory inclusion into Waters
of the States in 1993 (EPA 1990). They have historical-
ly been regulated under Section 404 of the Clean
Water Act, and although water quality is an issue in
404 decisions, it has not been the driving variable. The
presentation is based on the premise that a range of
criteria are necessary to protect wetland ecological in-
tegrity from a range of stressors. The author will dis-
cuss possible protective criteria, some in use in exist-
ing regulatory programs and others under develop-
ment. The order of presentation is biological, aquatic
life, hydrologic, sediments and wildlife criteria. In the
conclusion, the author briefly discusses using land-
scape approaches to extrapolate criteria to spatial
scales beyond the traditional site-specific analysis
used in most water quality decisions.

Minnesota's 3.6 million ha of wetlands have been im-
pacted by a variety of human activities, including agri-
cultural drainage, urbanization, water control, and non-
point source pollution. More than half of Minnesota's
wetlands have been destroyed since the first Europe-
an settlers arrived, an average loss of about 35,600
ha/yr. Drainage for agriculture is the major cause of
wetland loss in Minnesota, particularly in southern Min-
nesota and the Red River Valley. In addition to impact-
ing wetlands directly, wetland drainage affects down-
stream areas by increasing flood flows, and releasing
sediment and nutrients. Urban development and high-
way construction affect a smaller proportion of Minne-
sota's wetlands, but substantially alter their physical,
chemical, and biological properties. Hydrology has a
major influence on the structure and function of wet-
lands, so changes in the frequency, duration, depth,
and timing of wetland flooding can severely impact
wetlands. White wetlands can assimilate tow levels of
sediment and nutrient enrichment, excessive inputs
can be detrimental. Peat harvesting is not currently ex-
tensive in Minnesota, but could cause substantial im-
pacts. Cumulative impact the incremental impact of an
action when added to other past, present, and reason-
ably forseeable future actions, is becoming an area of
increasing concern.

Included are data obtained when LAAW was being
treated at the Los Angeles Aqueduct Filtration Plant
and similar data obtained during a two-day experiment
in which the plant was treating SPW. Some batch-
scale ozonation studies are also reported. Ozonation
by-products were monitored using three methods:
closed-loop stripping analysis, nonionic resin accumu-
lation, and a direct aqueous derivatization method for
low-molecular-weight aldehydes, each followed by gas
chromatography-mass spectrometry analysis of the
extracts. The major neutral by-products appear to be
aliphatic aldehydes, but the levels are unexpectedly
low in SPW compared with LAAW treated under similar
conditions. Low levels of several other compounds
were found in ozonated water, including bromoform
and some compounds tentatively identified as ke-
tones.

Experimental data are presented to test a kinetic
model of the OE/H2O2 process in a semibatch reac-
tor. The effect of bicarbonate and carbonate ions is
measured and found to be in concurrence with model
predictions. The effect of pH in the ozone mass-trans-
fer-limited region was examined in bicarbonate-spiked
distilled water. Since the reaction is mass transfer limit-
ed, the primary effect above pH 7 is the result of
changes in the distribution of inorganic carbon species
which are OH-radical scavengers. Below pH 7, there is
a lag period during which, ozone and peroxide increase
until the chain reaction begins. The effects of chloride
ion and the concentration of radical scavengers other
than carbonate species in ground waters are also
measured. The mass-transfer/reaction rate model has
been used to estimate rate constants for the reaction
of hydroxyl radicals with trichloroethylene, 1,2-dibro-
moethane, l,2-dibromo-3-chloropropane, carbon tet-
rachloride, and two bicyclic alcohols, 2-methylisobor-

of the model that remain unresolved when the matrix is
changed to a real surface or ground water. This and
subsequent papers will investigate these effects.

A model is presented that describes the kinetics of the
oxidation of micropollutants in water with the combina-
tion of ozone and hydrogen peroxide in a sparged, se-
mibatch reactor. The model is based on known reac-
tions of the O3/H2O2 system plus mass-transfer char-
acteristics of the reactor. The principal kinetic species
for micropollutant oxidation is assumed to be the hy-
droxyl radical. The model is tested and validated in dis-
tilled water spiked with an excess of bicarbonate, a
known hydroxyl radical scavenger.

The field study was conducted to test the hypothesis
that plants chronically exposed to O3 may be more
susceptible to drought because O3 typically inhibits
root growth and increases shoot-root ratios in plants.
Cotton was grown in open-top chambers on Hanford
coarse sandy loam in Riverside, CA. Plants were
grown under three irrigation regimes: optimum water
for lint production (OW), suboptimum or moderate
drought stress (SO), and severely drought stressed
(SS) and were exposed to seasonal 12 h (0800-2000)
O3 concentrations of 0.015,0.074,0.094, or 0.111/mi-
croLL. Leaf xylem pressure potentials Psifsub 1) and
soil water content Theta(sub v) were measured weekly
from June to October. Mean seasonal Psi(sub 1) in-
creased from -1.89 MPa to -1.72 MPa in low to high 03
treatments, averaged across soil water regimes.
Ozone had no effect on seasonal water use of cotton,
but water use efficiency was significantly reduced by
O3 in OW and SO, but not in SS treatments. Drought-
stressed plants extracted proportionally greater
amounts of water from deeper in the soil profile than
OW cotton, and O3 had no apparent effect on this re-
distribution of roots in the soil. Since O3 had no appar-
ent effect on the ability of drought-stressed cotton to
maintain Psi(sub 1) and to increase root growth rela-
tive to shoot growth, this suggests that O3 may have
little or no effect on the potential of cotton to adapt to
or tolerate drought.

The quanitative significance of the surface microlayer
(SMI) to the environmental fate of the industrial plasti-
cizer di(2-ethylhexyl)phthalate (DEHP), in marine
coastal systems was established by the use of experi-
mental microcosms. The effects of season, sea-state
and associated solvents were investigated. The re-
sults demonstrated that the SML community rapidly
degraded DEHP to such an extent that under certain
treatment conditions biodegradation was the dominant
removal process compared with physical transport.
Biodegradation of DEHP by trie SML biota was esti-
mated to account for at least 30% of the total budget.
Extrapolation of the laboratory results to the simulated
field system (the West Passage of Narragansett Bay,
Rl), is discussed within the context of potential arti-
facts of the marine microcosms. (Copyright (c) 1990-

A total of over 32,000 demersal fish and epibenthic
crustaceans belonging to 62 species were caught in
42 biweekly trawls from 10 stations in Yaquina Bay,
Oregon, during 1967 and 1968. English sole, Par-
ophrys vetulus, was the most abundant species. Sev-
enteen species (13 fishes and 4 crustaceans) consti-
tuted 95% of the catch. Total numerical abundances
of both individuals (mainly juvenile fishes) and species
were greatest in the lower 12 km of the estuary during
summer and early fall, a period of water mass stability
and increased water temperature and salinity. This
section of the estuary is used by many immature fishes
and crustaceans as a 'nursery area.' These fishes gen-
erally emigrate from the estuary as subadults in the fall
around the onset of the rainy season. The fewest spe-
cies were taken in January 1968 from the central,
upper-estuarine, and riverine areas of the bay, this
being a time when high rainfall and river discharge
result in low salinity and temperature. Crustaceans
(shrimp and subadult crabs) were generally most
abundant in late winter and early spring throughout the
estuary. Changes in diversity indices reflected vari-
ations in community structure, the influences of migra-
tory species and juvenile fishes, and seasonal
changes in dominance. Year-to-year fluctuations in
abundance may be due, in part, to local hydrographic
and meteorological conditions along the central
Oregon coast. (Copyright (c) 1990 Estuarine Research

An infrared video camera and recording system were
used to record near-source plume rise from a low tur-
bine stack on an oil-gathering center at Prudhoe Bay,
Alaska. The system provided real-time, continuous vis-
ualization of the plume using a color monitor while the
images were recorded with a standard video tape re-
corder. Following the field study, single frame images
were digitized using a micro-computer video system.
As part of the digitization, the plume centerline was
captured as well as an isotherm of the plume outline. In
the application, one frame from each two-minute
period in the record was captured and digitized. The
results were used to calculate the variability in plume
centerline during each hour. During strong winds with
blowing snow, the mean plume rise for the hour at 15
m downwind was 6 + or - 2 m. The observed plume
rise from the turbine stack was greater than that calcu-
lated using momentum-only, buoyancy-only, or com-
bined momentum-buoyancy plume rise models.

Salmonella typhimurium strain TA100 was exposed to
a series of peroxyacyl nitrates including peroxyacetyl
nitrate (PAN), peroxypropionyl nitrate (PPN), peroxy-
butyryl nitrate (PBN), peroxybenzoyl nitrate (PBzN),
and chloroperoxyacetyl nitrate (CPAN). Gas phase
concentrations for the individual exposures were in the
high ppbv range. The dose was determined from the
deposition rate and measured from the net decrease
of the test compound in the exposure chamber and the
exposure time. The mutagenic activity for each com-
pound determined from the dose-response relation-
ship gave values ranging from 250 (PBN) to 6570

Three mobile continuous analyzers and an array of
fixed sequential syringe samplers were used to meas-
ure plume dispersion rates of SF6 released from a 300
m tower in Beijing during strong, steady winds with
neutral conditions. The plume trajectories over the flat,
open terrain downwind of Beijing were relatively
straight.- Predicted plume trajectories based on inter-
polated wind fields from surface and upper air data ex-
hibited a mean separation error of 4 km at 70 km
downwind. Maximum predicted concentrations from a
Gaussian puff model agreed within a factor of two with
observed surface profiles when the source was given
an initial vertical distribution to account for the effects
of wind shear upon horizontal dispersion. Short-term
(i.e., 10 to 20 min averaging time) horizontal dispersion
rates were essentially equal to the neutral Pasquill-Gif-
ford curve. Dispersion coefficients from hourly-aver-
aged concentration profiles were 30% larger than the
PG neutral curve, but 50% smaller than a linear neutral
curve based upon dispersion data collected downwind
of a power plant.

New carpeting has been the source of a number of
indoor air health and odor complaints. Investigations of
a variety of carpet samples have shown that there is a
diversity of organic emissions among carpet types;
some of the compounds found have been listed in the
NIOSH Registry of Toxic Effects of Chemical Sub-
stances. The paper describes two complementary an-
alytical methods for screening carpet samples, a
'headspace' method for volatile emissions and a Soxh-
let extraction method using methylene chloride for the
semi-volatile and non-volatile compounds. The analyti-
cal results from seven carpet types are presented with
special emphasis on the compound 4-phenylcyclohex-
ene, one of the causes of 'new carpet smell,' which
has also been anectdotally linked to adverse short
term health effects. Other compounds of possible in-
terest that were found include dichlorobenzene, bis(2-
ethylhexyl)-phthalate, triethyl phosphate, epsilon-ca-
prolactam, and methylene-bis(4-isocyanatobenzene).

The importance of the dry deposition of aerosols as a
pathway for the transfer of alkaline material to ecosys-
tems is discussed, as is the difficulty investigators face
when trying to measure such deposition. Accordingly,
an inference technique is developed which allows for
the estimation of the annual and monthly dry deposi-
tion of Ca(2+), Mg(2+), Na(+) and K(+), based upon
the linear relationship exhibited between the measured
surface concentrations and wet deposition at 23 sta-
tions in Ontario, Canada for the period 1983-1985.
Theoretically, this inference technique is based upon
the premise that precipitation efficiently scavenges the
aerosols, resulting in a strong correlation between
concentrations within precipitation and the surface air
concentrations. Because of the stochastic nature of
such an approach, care must be taken to ensure that
the assumptions inherent to precipitation scavenging
and therefore this inference technique are carefully
considered. Under such considerations, annual and
monthly dry deposition of the alkaline aerosols can be
estimated at many locations across North America
where wet deposition measurements are routinely
made. (Copyright (c) 1990 Kluwer Academic Publish-

Measurements of velocity and tracer plume concentra-
tions during stable atmospheric conditions were ob-
tained in the Boise river valley as part of the EPA Inte-
grated Air Cancer Project during December, 1986.
Wind speed, temperature, and wind direction were
measured at two levels on a 30 m tower. Spectral and
autocorrelation analyses of the velocity component
data dearly indicate the occurrence of wave-like oscil-
lations in the flow and almost complete lack of turbu-
lent energy. The predominate wave-like motion had an
oscillation period of about 1000 s. Hourly averaged
horizontal dispersion coefficients were very large com-
pared to the Pasquill-Gifford curves and the urban
McElroy-Pcoter dispersion curves. The time-averaged
dispersion coefficients formed an upper bound on very
short-term dispersion coefficients obtained from
mobile traverses of the tracer plume with a continuous
SF6 analyzer. Vertical dispersion rates were slightly
smaller than the Pasquill-Gifford class F curve. Results
from a single tracer release from a side canyon near
the neighborhood showed that drainage flow from the
tributary impacted the main residential sampling site at
Elm Grove Park and represented a significant fraction
of the upstream air flow at Elm Grove Park. For
sources with equal emission rates, a source in the trib-
utary adds about 10% to the mean of the concentra-
tion caused by a neighborhood source.

Urine from cigarette smokers was analyzed for the
effect upon mutagenic activity when stored for as long
as 175 days. Frozen aliquots of urine were thawed out
at various time points in the study and prepared for bio-
assay. These urine extracts were not bioassayed im-
mediately, but rather refrozen until all of the unproc-
essed urine samples had eventually been prepared for
bioassay. All extracts were obtained using cyanopropyl
solid phase extraction techniques. At the end of 175
days, all extracts were bioassayed using a microsu-
spension assay of Salmonella typhimurium TA98.
Urine from smokers was found to be mutagenic (14.4-
30.9 revertants/ml equivalent) while a control set of
urine from nonsmokers was not. Data from the storage
study when analyzed by analysis of variance tech-
niques indicated no statistical loss of mutagens oc-
curred over the 175-day period although near signifi-
cance was observed (P = 0.054). This near signifi-
cance was the result of decreasing mutant response
as storage time increased for two of the higher doses
tested. (Copyright (c) 1990 Wiley-Liss, Inc.)

A method for predicting reactivity parameters of organ-
ic chemicals from spectroscopic data is being devel-
oped to assist in assessing the environmental fate of
pollutants. The prototype system, which employs mul-
tiple linear regression analysis using selected points
from the Fourier transforms of mid-infrared gas-phase
spectra, has been applied to the prediction of the alka-
line hydrolysis rate constants (kOH) of 41 carboxylic
acid esters. True predictions (calculations made for
compounds not used to generate the calibration equa-
tion on which the prediction is made) of log kOH aver-
age within 43% of the experimental value for 36 of the
esters (about 88% of the data set). For these com-
pounds, a plot of calculated versus predicted log kOH
values yields a correlation coefficient of 0.887.

The effect of correlation among the input parameters
and variables on the output uncertainty of the Streeter-
Phelps water quality model is examined. Three uncer-
tainty analysis techniques are used: sensitivity analy-
sis, first-order error analysis, and Monte Carlo simula-
tion. A modified version of the Streeter-Phelps model
that includes nitrification, net algal oxygen production,
and sediment oxygen demand is used. Analyses are
performed for a wide variety of simulated stream flow
conditions. Results show that the standard deviation of
the predicted dissolved oxygen deficit (DOD) with cor-
related inputs potentially can be 20-40% larger than
with independent inputs. Under conditions of moderate
to high velocity, the reaeration and bio-oxidation coeffi-
cients are the dominant contributors to DOD uncertain-
ty, while net oxygen production from algal activity and
sediment oxygen demand are the major factors at low
velocity. The largest effect of input correlation on DOD
occurs in the vicinity of the sag point. Uncertainty re-
sults from first-order analysis differ by at most 10%
from those of a Monte Carlo simulation for both corre-
lated and independent inputs. (Copyright (c) 1990,

Fresh and dichlorophenol (DCP)-adapted sediments
from two ponds near Athens GA exhibited distinctly dif-
ferent dechlorinating activities. These differences cen-
tered on the relative rates of reductive dechlorination
in both fresh and adapted sediments and on the sub-
strate specificity of the adapted sediments. Fresh
Cherokee Trailer Park Pond sediment dechlorinated
2,3-, 2,4- and 2,6-DCP to monochlorophenols at a
faster rate and after a shorter lag period than fresh
Bolton's Pond sediment. Lag periods were not ob-
served in e.ither Cherokee or Bolton's sediments that
had been adapted to dechlorinate either 2,3-, 2,4- or
2,6-DCP. Adapted Cherokee sediments exhibited
faster dechlorinating rates and a broader substrate
specificity than the adapted Bolton's sediments. The
broad substrate specificity of each of the adapted
Cherokee sediments contrasted sharply with the

Significant quantities of Ag(l), Cu(ll), and Cr(lll) were
bound to isolated Bacillus subtilis 168 walls, Escheri-
chia coli K-12 envelopes, kaolinite and smectite clays,
and the corresponding organic material-clay aggre-
gates (1:1, wt/wt). These sorbed metals were leached
with HNO3, Ca(NO3)2, EDTA, fulvic acid, and lyso-
zyme at several concentrations over 48 h at room tem-
perature. The remobilization of the sorbed metals de-
pended on the physical properties of the organic and
clay surfaces and on the character and concentration
of the leaching agents. Cr was very stable in the wall,
clay, and composite systems; pH 3.0, 500 microM
EDTA, 120-ppm (mg/liter) fulvic acid, and 160-ppm Ca
remobilized less than 32% (wt/wt) of sorbed Cr. Ag
(45 to 87%) and Cu (up to 100%) were readily re-
moved by these agents. Although each leaching agent
was effective at mobilizing certain metals, elevated Ca
or acidic pH produced the greatest overall mobility.
The organic chelators were less effective. Lysozyme
digestion of Bacillus walls remobilized Cu from walls
and Cu-wall-kaolinite composites, but Ag, Cr, and
smectite partially inhibited enzyme activity, and the
metals remained insoluble. The extent of metal remo-
bilization was not always dependent on increasing
concentrations of leaching agents; for example, Ag
mobility decreased with some clays and some com-
posites treated with high fulvic acid, EDTA, and lyso-
zyme concentrations. It is apparent that remobilization
of toxic heavy metals in sediments, soils, and the
vadose zone is a complicated issue.

The octanol-water distributions of 10 environmentally
significant organic acid compounds were determined
as a function of aqueous-phase salt concentration
(0.05-0.2 M LiCI, NaCI, KCI, CaCI2, or MgCI2) and pH.
The compounds were pentachlorophenol, 2,3,4,5-te-
trachlorophenol, (2,4,5-trichlorophenoxy)acetic acid,
4-chloro-alpha-(4-chlorophenyl)benzeneacetic acid, 2-
methyl-4,6-dinitrophenol, (2,4-dichlorophenoxy)acetic
acid, 4-(2,4-dichlorophenoxy)butanoic acid, 3,6-dich-
loro-e-methoxybenzoic acid, 2,3,6-trichlorobenzenea-
cetic acid, and 2-(2,4,5-trichlorophenoxy)propionic
acid. The experimental results were interpreted quanti-
tatively with an equilibrium model that accounts for
acid dissociation in the aqueous phase and partitioning
into the octanol phase by the neutral organic species,
free inorganic and organic ions, and ion pairs. The par-
tition constants for the neutral ion pairs correlate well
with the partition constants of the neutral acids. Two
experiments address the applicability of these octanol-
water distribution data to the distribution of ipnogenic
compounds in the environment: the distribution of 2-
methyl-4,6-dinitrophenol on a natural sorbent as a
function of salt concentration (NaCI and CaCI2) and
pH, and competitive adsorption of pentachlorophenol
and 2,3,4,5-tetrachlorophenoI on an environmental
sorbent. (Copyright (c) 1990 American Chemical Soci-

The authors propose a novel mechanism for isotopic
exchange between CO2 and O3 via O ((1)D) + CO2 -
> CO3 followed by COS -> CO2 + O((3)P). A one-di-
mensional model calculation shows that the mecha-
nism can account for the enrichment in 18O in the
stratospheric C023 observed by Gamo et al. (1989),
using the heavy O3 profile observed by Mauersberger
(1981). The implication of the mechanism for other
stratospheric species and as a source of isotopically
heavy CO2 in the troposphere are briefly discussed.

During a one-month period in the fall of 1987 a wide
range in the visual quality of the atmosphere at Re-
search Triangle Park, NC, was observed. During the
period, the light scatter coefficient; SO2, N02, and O3
concentrations; temperature; relative humidity; and ra-
diation intensity of the atmosphere were continuously
monitored. In addition, 60 filter samples were intermit-
tently collected with two dichotomous (large and small
particle) size-selective samplers. The dichotomous
samplers were operated concurrently to obtain sam-
ples on Teflon and quartz filters for different analyses.
Also collected were six impactor samples for sulfate
size distribution analysis; and at selected times during
the study, long-path measurements were made of the
atmospheric extinction coefficient and the extinction of
contrast by the atmosphere. (Copyright (c) 1991 -Air &

The product distributions have been calculated for the
more abundant alkanes contributing most of the
carbon atoms in the alkane fraction of an ambient air
hydrocarbon mixture reasonably representative of U.S.
emissions. The effects of ambient temperatures on
product yields has been calculated for a range of tem-
peratures from 250K to 330K. Chemical lifetimes are
estimated at 300K under summertime conditions for
hydrocarbons and for products of alkane photooxida-
tion in the atmosphere. The calculations predict a sub-
stantial effect of temperature on product yields. A large
decrease in alkyl nitrate yields and a smaller decrease
in ketpne yields occurs with increasing temperature.
The yields of the short-lived more reactive aldehydes
undergo substantial increases with increasing temper-
ature. Four lower molecular weight oxygenated prod-
ucts account for over half of the total alkane carbon
atoms converted to products. The effects of increased
temperature on product reactivity and radical produc-
tion may also influence 03 production.

According to the fugacity approach (Mackay 1979),
pollutant uptake by an organism is determined by the
chemical fugacity differential between the organism
and its environment. The Accumulation Factor (AF =
(concentration of pollutant in animal tissue, C(sub t)
(nanograms/g dry wt)/animal lipid {%/100))/(concen-
tration of pollutant in sediment, C(sub s) (nanograms/g
dry wt)/sediment total organic carbon, TOC (% /100)))
is a simple, fugacity-based model which has been
shown to be useful for predicting the bioaccumulatipn
potential of hydrophobic neutral organic compounds in
sediment-dwelling animals (Rubinstein et al. 1987;
McElroy and Means 1988; Clarke et al. 1988; Ferraro
et al. 1990). The theoretical basis for the AF model is
discussed in Mackay (1979), Mackay and Paterson
(1981, 1982), McFarland (1984), McFarland and
Clarke (1986), and Lake et al. (1987). The model as-
sumes chemical equilibrium or steady-state in the ani-
mals and the sediments to which they are exposed, no
chemical transformation or phase transfer resistance,
and chemical partitioning primarily between the organ-
ic pool in the sediment and the lipid pool in the animal.

A toxicity-based method to identify nonpolar organic
toxicants in effluents has been developed. The
method has low artifactual toxicity and excellent de-
tection limits, allows multiple toxicant situations to be
easily handled, and features the use of cladocerans
and fishes as test organisms and gas chromatogra-
phy/mass spectrometiry (GC/MS) to identify the toxi-
cants. The method uses reverse-phase chromatogra-
phy techniques to extract and fractionate the nonpolar
organic toxicants from the effluent. GC/MS analyses
are performed on the toxic fractions, and lists of tenta-
tive compound identifications are made by interpreta-
tion of the mass spectra and elution information from
trie chromatographic separations. These initial lists are
refined by assembling and then comparing toxicity
data of the identified chemicals to the toxicity of the
fraction. The refined lists of suspect chemicals are fur-
ther evaluated by pure chemical toxicity testing, and
this process ultimately leads to toxicant identification.
The fractionation scheme, instrumental parameters,
the toxicant identification process, an example illus-
trating the method, and discussion relevant to the
method are presented. (Copyright (c) 1991 American

Viewing microbial habitats as interacting zones of pro-
liferation and quiescence can give new insights into
the operation of microbial communities in the environ-
ment. Microorganisms proliferate in diverse circum-
stances and are the principal mediators of many proc-
esses affecting the world. However, not all microorga-
nisms are reproducing. The total microbial biomass, in
fact, includes many cells in a state of suspended ani-
mation, or quiescence. Although scant attention is usu-
ally given to this 'sleeping' portion of the microbial
community, quiescent microbes may be critically im-
portant in ecosystems, especially in system-level re-
sponses to environmental changes. Quiescent mi-
crobes play roles in processes such as photosynthe-
sis, nutrient cycling, and productivity. Thus, from the
perspective of ecological studies, it is particularly im-
portant to expand the research focus beyond the tradi-
tional examination of what microorganisms are doing
when they are doing something. This expanded ap-
proach would include studies of where, when, and how
quiescent microbial forms occur in the environment
and the ramifications of temporarily storing various
fractions of microbial populations in a quiescent state.

3,4-methylenedioxymethamphetamine (MDMA), a
substituted amphetamine analogue which stimulates
serotonin release in the CNS, has been shown to
induce near lethal elevations in core temperature in
the rat. To characterize the effects of MDMA on tem-
perature regulation, the study measured metabolic
rate (MR), evaporative water loss (EWL), motor activity
(MA), and colonic temperature (Tc) in male, Long-
Evans rats at 60 min following 30 mg/kg (s.c.) MDMA
or saline at ambient temperatures (Ta) of 10, 20, and
30C. MDMA caused an elevation in MR at Ta's of 20
and 30C but had no effect at 10C. At a Ta of 30C, MR
of the MDMA group was double that of the saline
group. EWL was elevated by MDMA, an effect which
was potentiated with increasing Ta. MDMA also elicit-
ed an increase in MA at all three Ta's. MDMA led to a
3.2C increase in Tc at 30C, no change in Tc at 20C,
and a 2.0C decrease in Tc at 10C. The data suggest
that, at relatively warm Ta's, MDMA-induced stimula-
tion of serotonergic pathways causes an elevation in
MR and peripheral vasocpnstriction, thus producing
life-threatening elevations in Tc. The increase in EWL
following MDMA partially attenuates the hyperthermia
at warm Ta's and leads to hypothermia in the rat main-
tained at a cold Ta of 10C.

Recent studies using reptiles and other ectothermic
species have shown that hypoxia lowers the set-point
for the control of body temperature. This is character-
ized by a preference for cooler ambient (T(sub a)) and
deep body temperatures (T(sub b)) when placed in a
temperature gradient. To elucidate the presence of
this effect in mammals, the selected T(sub a) and
Tfsub b) of three rodent species, mouse, hamster, and
rat, were measured while subjected to graded hypoxia
in a temperature gradient. Individual animals were
placed in the gradient for 30 min. Percentage O2 of air
entering the gradient was then reduced to a constant
level for a period of 60 min by dilution with nitrogen.
T(sub b) was significantly reduced in all species at O2
levels of 5.5 to 10%. Selected T(sub a) was significant-
ly reduced in the mouse at O2 levels of 5.5 and 7.3%.
Selected T(sub a) of the hamster and rat were reduced
slightly at percentage O2 levels of 5.8 and 7.4%, re-
spectively; however, the effect was not statistically sig-
nificant. Both species exhibited a significant reduction
in selected T(sub a) during hypoxia concomitant with
hypothermia. These data support the hypothesis that
hypoxia lowers the set-point for the control of body
temperature in rodents.

The Chinese hamster ovary (CHO) assay, which meas-
ures newly induced mutations at the hypoxanthine-
guanine phosphoribosyltransferase (hgprt) locus, has
been widely used for mutagenesis testing. The insensi-
tivity of the standard assay to some genotoxic agents
has been speculated to be due to the relatively small
number of cells used in the assay. The present study
compares the standard monolayer assay with a sus-
pension adapted assay which uses cell numbers com-
parable to that of the L5178Y mouse lymphoma assay.
Nine compounds, ethyl methanesulfonate (EMS),
methyl methanesulfonate (MMS), 2-methpxy-6-chlpro-
9-(3-(ethyl-2-chloroethyl)-aminopropylamino)-acridine
2HCI (ICR 170), methyl acrylate, ethyl acrylate, te-
traethylene glycol diacrylate, trimethylolpropane tria-
crylate, 2-ethylhexyl acrylate, and dicyclopentenylox-
yethyl methacrylate were evaluated in the monolayer
and suspension assays. Both assays gave the same
overall positive/negative evaluation for the test com-
pounds. There were some quantitative differences in
the mutant frequency for the three compounds found
to be mutagenic (EMS, MMS, and ICR 170). The acry-
lates (many of which appear to exert their genotoxic
effect through a clastogenic mechanism) were nega-
tive in both test systems. The use of the suspension
assay did not improve the ability of the hgprt locus to
detect the genotoxicity of the acrylates.

Methods for assessing functional consequences of ol-
factory mucosal damage were examined in rats ex-
posed to 3-methylindole (3-MI). Treatment with 3-MI
(400 mg/kg) induced severe degeneration of olfactory
sensory epithelium followed by regeneration, fibrous
adhesions and osseous remodeling of the nasal pas-
sagas. At 100 mg/kg, there was mild Bowman's gland
hypertrophy while the sensory epithelium remained
intact. Rats treated with 3-MI demonstrated a dosage-
related deficit in acquiring an olfactory learning task
which was not due to altered cognitive abilities, as de-
termined by subsequent testing in a step-through pas-
sive avoidance task. The results confirm the conclu-
sion that alterations in functional indices resulted from
3-MI-induced anosmia and demonstrate the utility of
simple learning tasks in assessing functional capacity
following olfactory epithelial damage in rats. (Copyright

The study reports that CD-1 strain mice are neuropath-
ologically and biochemically responsive to acute
doses of tri-ortho-cresyl phosphate (TOCP). Young
(25-30 g) male and female animals were exposed (po)
to a single dose of TOCP (580-3480 mg/kg) and sam-
pled for neurotoxic esterase (NTE) activity at 24 and
44 hr postexposure and for neuropathic damage 14
days later. Biochemically, high intragroup variability ex-
isted at the lower doses, and at higher levels of TOCP
exposure (i.e., > or = 1160 mg/kg), mean brain NTE
inhibition never exceeded 68%. Hen and mouse brain
NTE activity, assayed in vitro for sensitivity to inhibition
by tolyl saligenin phosphate (TSP), the active neuro-
toxic metabolite of TOCP, showed similar IC50 values.
Histologically, highly variable spinal cord damage was
recorded throughout treatment groups and mean
damage scores followed a dose-response pattern with
no apparent correlation to threshold (i.e., > or =
65%) inhibition of brain NTE activity. Topographically,
axonal degeneration in the mouse spinal cord pre-
dominated in the lateral and ventral columns of the
upper cervical cord. Unlike the rat, which displays de-
generation in the upper cervical cord's dorsal columns
(i.e., gracilis fasciculus) in response to TOCP intoxica-
tion, treated mice showed minimal damage to this
tract. To examine this discrepancy further, ultrastruc-
tural morphometric analysis of axon diameters in the
cervical cord was performed in control mice and rats.
These results indicated that in both species, the larg-
est diameter (> or = 4 microm) axons are housed in
the ventral columns of the cervical spinal cord, sug-
gesting that axon length and diameter may not be the
only criteria underlying fiber tract vulnerability in

Despite their widespread use and potential for signifi-
cant human exposure, genotoxicity data on anthra-
quinones and other dyes are generally limited. The
study examined 16 anthraquinones and one azo dye
(Solvent Red 1) using the thymidine kinase (tk) locus
and micronucleus (MN) analysis in L5178Y/TK(sup
+ /-) -3.7.2C mouse lymphoma cells. Disperse Blue 7,
2-aminoanthraquinone, 1 -amino-2-methylanthraquin-
one, Disperse Blue 3, and Disperse Red 11 were geno-
toxic. Reactive Blue 19 was weakly mutagenic. Vat
Yellow 4 and Solvent Red 1, with exogenous activa-
tion, were also mutagenic. With activation 1-nitro-2-
methylanthraquinone was judged to give an equivocal
mutagenicity response. Those chemicals that did not
induce mutation or cytotoxicity at the limits of solubility
were classified separately. Compounds which were
not evaluated without exogenous activation because
of insolubility but were evaluated with activation in-
clude 1-nitro-2-methylanthraquinone, Solvent Red 1,
and Vat Yellow 4. Compounds which were not evaluat-
ed either with or without S-9 activation because of their
insolubility in the culture medium include 1 -amino-2,4-
dibromoanthraquinone, D&C Green, Disperse Blue 1,
Disperse Red 60, Vat Blue 4, Vat Blue 20, Vat Brown 1,

The physiological consequences of early neonatal
growth retardation in the kidney were investigated
using DFMO (alpha-difluoromethylornithine), a specific
irreversible inhibitor of prnithine decarboxylase (ODC),
a key enzyme in the biosynthesis of polyamines. The
study administered 500 mg/kg/day DFMO, or saline,
to Sprague-Dawley rat pups from the day of birth
through postnatal day (PD) 6 and evaluated renal func-
tion on PD 4, 7, 10, and 13 using tests of basal renal
clearance and urinary concentrating ability. Kidney
weights and gross pathology were also obtained. On
PD 39, serum chemistries and organ weights were de-
termined. In a second experiment, the study evaluated
concentrating ability on PD 7-10, and basal renal func-
tion, concentrating ability, diuretic response, serum
chemistries and organ weights on PD 132-140. DFMO
selectively inhibited renal growth, but did not inhibit
glomerular and tubular functional maturation. The
rates of filtration and reabsorption (per g renal tissue),
and concentrating ability were increased in treated
pups. The renal growth retardation induced by neona-
tal administration of DFMO was associated with an ap-
parent precocious maturation of function in the early
postnatal period and dysfunction in adulthood, thus
demonstrating that the physiological consequences of
growth retardation are not always obvious and predict-
able, and must be evaluated on a case by case basis.

The problems of developing and comparing statistical
procedures appropriate to the monitoring of ground
water at hazardous waste sites are discussed. It is sug-
gested that these decision procedures should be
viewed as quality control schemes and compared in
the same way that industrial quality control schemes
are compared. The results of a Monte Carlo simulation
study of run-length distribution of a combined She-
whart-CUSUM quality control scheme are reported.

Two candidate methods for the recovery and detection
of viruses in soil were subjected to round robin com-
parative testing by members of the American Society
for Testing and Materials 019:24:04:04 Subcommittee
Task Group. Selection of the methods was based
upon results of an initial screening which indicated that
both met basic criteria considered essential by the
task group. Both methods utilized beef extract solu-
tions to achieve desorption and recovery of viruses
from representative soils: a fine sand soil; an organic
muck soil; a sandy loam soil; and a clay soil. The Berg
method seemed to produce slightly higher virus recov-
ery values, however the differences in virus assay
tilers for samples produced by the two methods were
not statistically significant (p < or = 0.05) for any one
of the four soils. Despite this lack of a Method Effect,
there was a statistically significant Laboratory Effect
exhibited by assay liters from the independent versus
reference laboratories for two of the soils, the sandy
loam and clay.

An incineration test program was conducted at the US
Environmental Protection Agency's Incineration Re-
search Facility to evaluate the potential of incineration
as a treatment option for contaminated soils at the
Baird and McGuire Superfund site in Holbrook, Massa-
chusetts. The purpose of these tests was to evaluate
the mcinerability of these soils in terms of the fate of
arsenic and lead and the destruction of organic con-
taminants during the incineration process. The test
program consisted of a series of bench-scale experi-
ments with a muffle furnace and a series of inciner-
ation tests in a pilot-scale rotary kiln incinerator
system. The study reported in the paper was funded by
the Environmental Protection Agency under Contract

The primary objective of the U.S. Environmental Pro-
tection Agency's (EPA) efforts to address the indoor
radon problem is to reduce radon levels in buildings
throughout the country. Achieving the objective re-
quires a nationwide supply of capable radon mitigation
contractors. In the Indoor Radon Abatement Act of
1988, Congress authorized EPA to establish a pro-
gram to evaluate radon mitigation contractors and to
provide the information to the public in cooperation
with the States. The Radon Contractor Proficiency
(RCP) Program was developed to assist States, EPA
Regions, local government officials, and the public in
selecting contractors who have demonstrated their
proficiency in reducing indoor radon levels. The pro-
gram is managed by the EPA Office of Radiation Pro-
grams' Radon Division. Under the voluntary program,
radon contractors demonstrate their proficiency by
meeting specific Program requirements. Individual
contractors who meet these requirements are then
listed in periodic RCP Proficiency Reports.

The site was used to manufacture specialty intermedi-
ate chemicals for the producers of dyes, pharmaceuti-
cals, cosmetics, herbicides, and pesticides. The herbi-
cide Fenac (2,3,6-trichlorophenylacetic acid) is a major
on- and off-site contaminant. One-hundred-twenty-
eight soils were collected. Elutriates were prepared for
toxicity evaluation of water extractable constituents.
The chemical nature of the elutriates was so complex
that it was impossible to determine chemical cause/bi-
ological effect relationships based on chemical analy-
ses alone. Bioassays identified locations of toxicity on
the site without identifying the causative agents; impor-
tant because numerical criteria are not available for
many organic chemicals and there is little understand-
ing of the affects of mixtures of chemicals in complex
wastes on test organisms or the environment The
measured response represents an actual assessment
of any synergistic or antagonistic interactions. Fifty-
nine percent of the 128 elutriates were toxic to the
algae Selenastrum capricomutum and 43 percent
were toxic to Daphnia magna. Both organisms indicat-
ed that toxic sample numbers increased with depth of
sampling. The Toxi-chromotest (bacteria) revealed
toxicity in 2.3% of the 128 elutriates; all had been iden-
tified by algae and Daphnia. Ten elutriates were toxic
only to Daphnia and 30 only to S. capricomutum. Fifty-
one were toxic to both algae and Daphnia, but Daphnia
was most sensitive in only 8 elutriates. If one test was
used, 10 to 30 toxic elutriates would have not been
identified, depending on the test organism selected.

Four gasoline or gasoline-oxygenate blend fuels were
used in the evaluation of regulated and unregulated
emissions for five test vehicles. The fuels listed below
were all prepared from a common base gasoline and
were blended to have equal octane ratings. They were
Baseline, aromatic-enriched, 10% Ethanol blend,
16.4% Methyl tertiary-butyl ether (MTBE) blend, and
19.1 % Ethyl tertiary-butyl ether (ETBE) blend. The five
test vehicles represented different types of emissions
control technology: pre-catalyst. oxidation catalyst,
three-way catalyst with closed-loop carburetor oper-
ation and an air pump, three-way catalyst with throttle
body fuel injection, and three-way catalyst with port
fuel injection. Each vehicle was operated with each
fuel over the Federal Test Procedure (including evapo-
rative emissions) for a total of 15 tests per vehicle.
Several unregulated exhaust emissions were meas-
ured including ethylene, 1,3-butadiene, isobutylene,
benzene, toluene, o-, m-, and p-xylenes, formalde-
hyde, acetaldehyde, ethanol, MTBE, and nitrous oxide.
In addition, evaporative emissions were analyzed for
MTBE, benzene, and ethanol. The emission data from
tests using the ethanol, MTBE, and ETBE blends were
compared to emissions produced from tests using the
aromatic-enriched baseline fuel to determine if there
were any statistically significant differences associated
with the use of the blends.

The flow of petroleum hydrocarbons, organic solvents
and other liquids that are immiscible with water pre-
sents the nation with some of the most difficult subsur-
face remediation problems. One aspect of contami-
nant transport associated releases of such liquids is
the transport as a water-immiscible liquid phase. In the
document approximate models of immiscible flow are
presented for two- and three-phase flow. The approxi-
mations are constructed by representing the flow by
hyperbolic equations which have method of character-
istics solutions. This approximation has the additional
benefit of being based on the fundamental wave be-
havior of the flow, which is revealed by the solutions of
the models. An important result is that for three-phase
flow, two flow regimes exist The first is characterized
by the displacement of one of the liquids into a bank
which moves ahead of the other liquid. The second is
characterized by almost complete bypassing of a liquid
by the other. The occurrence of the flow regimes is de-
pendent on the organic liquid properties, soil type and
the initial amounts of the fluids present

The report contains procedures and example calcula-
tions for estimating air emissions that occur from treat-
ing contaminated material at Superfund sites. Emis-
sion factors for six treatment technologies are present-
ed. These are: (1) Thermal Treatment, (2) Air Stripping,
(3) Soil Vapor Extraction, (4) Solidification and Stabili-
zation, (5) Physical and Chemical Treatment, and (6)
Biotreatment and Land Treatment. For each of the six
technologies, a literature review was conducted to de-
velop a flow diagram and identify emission points, as
well as to analyze available air emissions data. For
most of the technologies examined, emission factors
were based on available data as well as assumed 'typi-
cal' operating conditions. Where possible, however,
emission factors were presented on actual operating
data from the site studies. Emission factors are pre-
sented for volatile organic compounds (VOC), metals,
particulate matter, SO2, NOx, CO, HCI, and HF. The
report also contains an extensive bibliography related
to waste treatment technologies.

Refined air toxics models are increasingly being used
to assess the impact of toxic air pollutants released
into the atmosphere. The purpose of the guidance
document is to provide general guidance consider-
ations for applying dispersion models to such releases
and to show the thought process required by the non-
expert user to develop all model input parameters.
Two example applications for each model are provided
with a step-by-step explanation of all model input pa-
rameters and model output. Four specific models are
currently included in the document. These are the DE-
GADIS, HEGADAS, and SLAB models appropriate for
denser-than-air releases and the AFTOX model for
neutrally buoyant releases of toxic air pollutants.

Basic Concepts of Contaminant Sorption at Haz-

The Regional Superfund Ground Water Forum is a
group of ground-water scientists, representing EPA's
Regional Superfund Offices, organized to exchange
up-to-date information related to ground-water remedi-
ation of Superfund sites. One of the major issues of
concern to the Forum is the transport and fate of con-
taminants in soil and ground water as related to sub-
surface remediation. Processes which influence the
behavior of contaminants in the subsurface must be
considered both in evaluating the potential for move-
ment as well as in designing remediation activities at
hazardous waste sites. Such factors not only tend to
regulate the mobility of contaminants, but also their

The availability of fate constants for 16 aqueous clean-
ers and terpenes is addressed. These compounds are
likely substitutes for chlorinated solvents and chloro-
fluorocarbons. Comparison of fate data available from
EPA's Office of Toxic Substances, the database
CHEMFATE, and additional fate data computed for the
report shows how few experimental values are current-
ly published. Almost all can be estimated, however,
using computational techniques.

EPA/540/4-90/054
Introduction and large scale production of synthetic
halogenated organic chemicals over the last 50 years
has resulted in a group of contaminants which tend to
persist in the environment and resist both biotic and
abiotic degradation. The low solubility of these types of
contaminants, along with their toxicity and tendency to
accumulate in food chains, make them particularly rel-
evant targets for remediation activities. Although the
processes involved in dechlorination of many of these
organic compounds are well understood in the fields of
chemistry and microbiology, technological applications
of these processes to environmental remediation are
relatively new--particularly at pilot or field scale. It is
well established, however, that there are several
mechanisms which result in dehalogenation of some
classes of-organic contaminants, often rendering them
less offensive environmentally. These include; stimula-
tion of metabolic sequences through introduction of
electron donor and acceptor combinations; addition of
nutrients to meet the needs of dehalogenating micro-
organisms; possible use of engineered micro-orga-
nisms; and use of enzyme systems capable of catalyz-
ing reductive dehalogenation.

TRACE). The data bases used in the evaluation are
the Desert Tortoise Pressurized Ammonia Releases,
Burro Liquefied Natural Gas Spill Tests and the Gold-
fish Anhydrous Hydroflouric Acid Spill Experiments. A
uniform set of performance statistics are calculated
and tabulated to compare maximum observed concen-

The paper summarizes the indicators proposed for a
pilot study by the U. S. Environmental Protection Agen-
cy's (EPA) Environmental Monitoring and Assessment
Program for lakes and streams (EMAP-LS). An addi-
tional lake and stream monitoring program is needed
because current programs do not provide regional or
national estimates of ecological condition or trends
with known levels of confidence. Because national and
regional monitoring must necessarily focus on spatial
issues, the authors explain why and how they concen-
trate their sampling at particular index periods and in
particular index locations. They provide 10 criteria for
selecting response indicators and outline the 18 indi-
cators selected and being developed for lakes and
streams. Finally, the authors discuss how they propose
to determine waterbody impairment through use of re-
gional reference sites, regional experts, historical data,
models, and empirical distributions of indicator values.

Most of the authors knowledge concerning the effects
of ultraviotet-B(UV-B) radiation was obtained with artifi-
cial UV radiation sources supplementing either artificial
white light in growth chambers, or solar radiation in
greenhouses and in the field. However, these artificial
sources do not precisely match the solar spectrum.
Few studies have documented the effects of UV-B on
total plant yield under field conditions. One notable ex-
ception is a six-year field study with soybean demon-
strating harvestable yield reductions under a simulated
25% ozone depletion. These effects are further modi-
fied by prevailing microclimatic conditions. Plants tend
to be less sensitive to UV-B radiation under drought or
mineral deficiency, while sensitivity increases under
low levels of visible light. Further studies are needed to
understand the mechanisms of UV-B effects and the
interactions with present stresses and future projected
changes in the environment.

An increasing awareness of declining amphibian popu-
lations in the United States requires that the authors
develop strategies for evaluating anthropogenic im-
pacts on wetlands and the biota dependent upon
these habitats. For example, in the western United
States, mining activities may impact a wetland and its
biota directly through habitat destruction or run-off of
sediments and contaminants generated during mining
operations. Amphibians which frequent these transi-
tion zones between terrestrial and aquatic habitats
may be key biological indicators of a wetland's status.
Through a demonstration project located in the mining
regions of western Montana, the authors are currently
using laboratory and field methods for a wetland eval-
uation required within a Superfund ecological risk as-
sessment.

The stability and transport of radio-labeled Fe2O3 col-
loids were studied using laboratory batch and column
techniques. Core material collected from a shallow
sand and gravel aquifer near Globe, Arizona was used
as the column matrix material. Scintillation counting
and laser light scattering with photon correlation spec-
troscopy (PCS) were used as means of colloid detec-
tion. PCS and scanning electron microscopy (SEM)
were used to verify the size of the colloids and their
stability. Variables in the study included flow rate, pH,
ionic strength, electrolyte composition (anion/cation),
colloid concentration, and colloid size. Transport was
highly dependant upon colloidal stability. Iron oxide
colloids in the 100-900 nm particle diameter range
were not only mobile to a significant extent, but under
some hydrogeochemica! conditions were transported
faster than a conservative tracer, tritium. The rate of
colloid transport was over 21 times that of the dis-
solved arsenate. Extent of breakthrough was depend-
ant upon a complex variety of parameters, however
the highest statistical correlation was observed with
particle size and ankmic composition of the supporting
electrolyte.

bustion (RWC), residential distillate oil combustion
(RDOC), and automotive emissions on the ambient
and indoor air quality. Consecutive 12-h samples were
collected over a 4-month period at three primary and
four auxiliary fixed sampling sites in each city. Each
ambient site consisted of one or more paniculate, or-
ganic, and gaseous samplers as well as selected crite-

participate, organic, and gaseous samples were con-
currently collected inside 10 pairs of residences in
each city over a 4-day period (2 weekdays and 2 week-
end days). Each pair of Boise residences consisted of
one home with and one home without an operating
RWC appliance. The pair of Roanoke residences con-
sisted of one home with and one home without an op-
erating RDOC appliance. Similar sample sets were col-

Data collected at ambient fixed sites may not ade-
quately reflect personal CO exposures, as they most
often miss exposures resulting from CO emissions
from sources in the immediate physical surroundings
of individuals, such as within automobiles. The SHAPE
model was proposed to account for this missing com-
ponent of exposure and provides the basis for the
model to be discussed. The viewpoint of the model
construct is to follow a person over a 24 or 48 hour
time interval. In the study, activity pattern data ob-
tained in the Denver, CO and Washington, D.C. are
used to define the sequence of microenvironments
and durations within each microenvironment. The
focus of the study is development of the concentration
values experienced by individuals over 1-hour and 8-
hour time periods.

A receptor modeling study was conducted in the
Tacoma tideflats airshed. The tideflats area is a small
but heavily industrial area adjacent to the Commence-
ment Bay waterway of Puget Sound. It is surrounded
by urban centers and rural and residential areas. Fine
and coarse particles were sampled tor 12 hours twice
daily beginning at 7 AM and 7 PM from 12/5/89
through 12/15/89 and from 1/2/90 through 1/8/90.
Concentrations of total fine particle mass, nitrate and
sulfate ions, organic carbon, elemental carbon, and a
suite of elements were measured in the fine particle
samples. Organic carbon was by far the dominant spe-
cies in the fine particle fraction. Gaseous species were
collected in evacuated canisters concurrently with par-
ticulate samples to measure volatile organic species
for the purpose of searching for potential motor vehicle
tracers. Receptor modeling results indicate that resi-
dential woodsmoke, not industrial sources, was the pri-
mary contributor (greater than half) to the total fine
particle mass. Other major sources identified by recep-
tor modeling are, in order of predominance, aluminum
production (one site only), residual oil boilers, motor
vehicle exhaust, scrap metal fugitives, and hogged fuel
boilers.

There is an increasing awareness of the need to sup-
plement site-specific environmental assessments with
those done at regional and global scales. In the paper,
the authors review some of the issues important to
broad-scale assessments. They then develop a re-
gional-scale assessment of environmental conditions
using fish assemblage data collected between 1983
and 1989 by the Ohio Environmental Protection
Agency from 2100 stream sites. They use Omernik's
ecpregions as the geographic framework and minimal-
ly impacted regional reference sites as definitions of
regional health. The authors evaluate native fish spe-
cies richness, the Modified Index of Well-being, and
the Index of Biotic Integrity to characterize regional
patterns in fish assemblage condition (as part of a
suite of potential indicators of environmental health).
For these three indicators, values at reference sites in
the Huron/Erie Lake Plain(HELP) were significantly
tower than in the other four ecoregions, demonstrating
a lower potential for supporting fish assemblages. Ref-
erence site values in the other four regions did not
differ substantially. Difficulties related to determining a
reference condition in regions with extensive land use
impacts are discussed. Regional indicator scores for
all sites (all levels of impacts) in the HELP were the
lowest, when compared to all reference site values
statewide. When index values from all sites were com-
pared to their ecoregional reference site scores, the
deviation in scores of HELP'S index values were com-
parable to or higher than all other regions. Regional
index values for all sites in the Erie/Ontario Lake Plain,
which is heavily industrialized, were the second lowest
compared to the statewide models, and the lowest
when compared to its own regional model. .In the
study, the simplest indicator (species richness) pro-
duced essentially the same regional-scale assessment
of environmental health as did more complex indica-
tors. These results imply that valid assessments of ec-
ological condition may be made at regional scales
using simple indicators when more complex indices
are not available.

The publication will examine some of the practices
being used or considered for use at on-site or commer-
cial hazardous waste treatment, storage and disposal
facilities (TSDF). Options for managing hazardous
wastes containing heavy metals and/or cyanide com-
pounds involve conventional treatment processes, re-
cycle/reuse applications and waste minimization.
Some of the technologies to be reviewed in this sec-
tion include: precipitation applications such as hydrox-
ide (e.g. lime, magnesium and iron oxyhydroxide), sul-
fide and carbonate systems; reduction techniques em-
ploying chromium, mercury and selenium reducing
agents; adsorption/selection techniques using activat-
ed carbon ion exchange and hydrous solids; stabiliza-
tion/fixation with discussion on applications, interfer-
ences and landfill design; cyanide destruction, includ-
ing chemical oxidation (e.g. alkaline chlorination, ozon-
ation/photolysis), electrolytic decompostion and incin-
eration; and pollution prevention measures such as
source reduction, recycling and reuse. Each of these
options will be described in terms of effectiveness of
treatment in removing the hazardous constituents of
interest and characterization of the generated treat-
ment residuals or in the case of waste minimization
practices, the degree to which the constituents of con-
cern are eliminated at the point of waste generation.

The paper summarizes results of a literature search
into the sources, sizes, and concentrations of particles
in indoor air, including the various types: plant, animal,
mineral, combustion, home/personal care, and radio-
active aerosols. The information, presented in a sum-
mary figure, has been gathered for use in designing
test methodologies for air cleaners and other mitiga-
tion approaches and ti aid in the selection of air clean-
ers. (NOTE: As concern about indoor air quality has
grown, understanding indoor aerosols has become in-
creasingly important so that control techniques may be
implemented to reduce damaging health effects and
soiling problems. Particle diameters must be known to
predict dose or soiling and to determine efficient miti-
gation techniques.)

Vacuum cleaner operations appear to be a significant
source of indoor aerosol particles as shown by limited
measurements carried out in randomly selected resi-
dences. The objective of the study is to measure aero-
sol particle emission rates under well-defined and con-
trolled conditions that are representative of general
vacuum cleaning operations. Residential upright
carpet vacuum cleaners were studied. The authors de-
termined from the data obtained by this procedure: (1)
the total aerosol particle emission rate for the vacuum-
ing process and (2) the particle size distribution of the
reentrained particles.

Use of Glial Fibrillary Acidic Protein in First-Tier
Assessments of Neurotoxicity.
Health Effects Research Lab., Research Triangle

J. P. O'Callaghan. 1991,29p EPA/600/D-91 /050
Diverse neurotoxic insults result in proliferation and hy-
pertrophy of astrocytes, a subtype of central nervous
system glia. The hallmark of the response, often
termed 'reactive gliosis', is the enhanced expression
of the major intermediate filament protein of astro-
cytes, glial fibrillary acidic protein (GFAP). These mor-
phological observations suggest that GFAP may be a
useful biochemical indicator of neurotoxicity. To inves-
tigate the possibility the authors administered proto-
type neurotoxicants to experimental animals and then
assessed the effects of these agents on the tissue
content of GFAP, as determined by radioimmunoas-
say. The study found that assays of GFAP reveal dose-
time- and region-dependent patterns of neurotoxicity
at toxicant dosages below those that cause light mi-
croscopic evidence of cell loss or damage. No false
positives have been seen following exposure to a vari-
ety of pharmacological agents. By using regional as-
sessments of GFAP in a first-tier evaluation, it should
be possible to localize areas of damage. A second-tier
evaluation, using assays of proteins or transmitters as-
sociated with cells in the affected region, may reveal
the cellular targets of neurotoxicity.

held in June, 1991.
The mandatory quality assurance program require-
ments for the U.S. Environmental Protection Agency
(EPA) have been in place for more than ten years, as
have two critical pieces of guidance which described
the development of QA Program Plans and QA Project
Plans. During the period, the absence of a formal
standard or criteria for QA fay the EPA has led to vary-
ing interpretation of the guidance by different groups,
both inside and outside the Agency. The situation has
frequently created confusion and uncertainty among
those who must prepare and implement the QA plans
as well as among those who must review and approve
them. EPA has been working with other Federal agen-
cies and the private sector to develop a national con-
sensus standard for QA/QC activities performed in
support of environmental programs, which may be
adopted and used Government-wide. In anticipation
that a standard will emerge from the process, EPA has
begun to reflect the proposed standard by revising old
guidance and developing new guidance for use both
by EPA and the general public. The paper discusses
the current status of the standard and of EPA guid-
ance, and how both will provide increased consistency
and uniformity in the 1990s.

Regional scale (approximately 1000 km) air quality
simulation models require hourly inputs of u and v wind
components for each vertical layer of the model and
for each grid cell in the horizontal. The standard North
American meteorological observation network is used
to derive the wind field inputs for the Regional Oxidant
Model (ROM) and other regional models. While a fairly
dense surface network with hourly observations exists,
upper air data are obtained only twice per day at moni-
toring sites typically separated by 300-500 km dis-
tances. Using these data to derive the more spatially
and temporally resolved gridded wind fields needed by
the ROM introduces uncertainties and errors into the
model. The authors present a method of developing
gridded wind fields for the ROM that accounts for
these non-deterministic features. The method pro-
duces a family of potential gridded wind fields allowing
for the stochastic nature of the interpolation process.
Examples of the derived wind fields are given for the
Northeast U.S. Potential differences between the wind
fields, in terms of their effects on air quality modeling,
are inferred from following multi-day flow trajectories
using various members of the wind field family.

A series of Urban Airshed Model (UAM) simulations
were performed using inputs derived from Regional
Oxidant Model (ROM) data files. The gridded ROM re-
sults employed in the UAM simulations included con-
centrations for specifying initial and boundary condi-
tions, wind fields, other meteorological and surface
geophysical parameters, and biogenic emissions. Two
approaches were applied to nest the 3-D UAM grid (a
four and a five level scheme) inside the regional model
grid framework. The model sensitivity study was con-
ducted with the variation in a single gridded input pa-
rameter or method in order to assess the impact on
ozone concentrations for different high ozone days
during 1980 over a domain covering the greater New
York metropolitan area. Differences in the domain
peak ozone and maximum ozone concentration at indi-
vidual grid cells from the sensitivity runs are compared
to base case simulations for each day. Maximum
ozone levels were examined for different wind fields,
with/without surface land use for the dry deposition
method, with/without biogenic emissions, and the
number of UAM vertical levels and nesting approach
for initial and boundary concentrations. The magni-
tudes of peak ozone concentration changes from sev-
eral sensitivity simulations were found to be compara-
ble to those obtained from previous model runs with
emissions control strategy reductions for the greater
New York City urban domain.

The U.S. Environmental Protection Agency (EPA) eval-
uated a differential optical absorption spectrometer
(DOAS) long path pollutant monitoring system during
July and August of 1990 in Atlanta, GA. Federal Refer-
ence Method (FRM) instruments and a gas chromato-
graph (GC), which measure a number of gas phase air
pollutants at a point, were operated concurrently as
part of a larger US EPA study of ozone and its precur-
sors in Atlanta. The DOAS was configured to measure
the pollutant concentrations of SO2, NO2,03, nitrous
acid, formaldehyde, benzene, toluene and o-xylene
over two open paths with 1099 m and 1824 m, respec-
tively, between light source and light receiver. Nitric
oxide (NO) and ammonia (NH3) were measured over a
third path of only 143 m. In the communication the fea-
tures of the DOAS system are described and results of
the Atlanta, GA evaluation of the system are dis-
cussed. Comparisons are made between the DOAS
open path measurements and FRM or GC measure-
ments made concurrently at a location near the DOAS

The U.S. EPA's Risk Reduction Engineering Laborato-
ry is conducting an inventory of constructed wetlands
(CW) for muncipal wastewater treatment in the U.S.
The inventory is one part of an effort to gather better
data on which to base CW design. The inventory is
being conducted in two phases; the paper presents
data from the first phase. A total of 143 communities
were identified as either considering or using CW. Of
this total, 31 operating free water surface (FWS) and
26 operating subsurface flow (SF) systems were
found. Systems range in size from 200 to 76,000 cu m/
d (0.05 to 20 mgd) for FWS and from 5 to 11,400 cu ml
d (0.001 to 3.0 mgd) for SF. Design approaches and
performance goals vary widely: as a result hydraulic
loading rates and costs vary widely. Limited flow data
show hydraulic surface area loading rates range from 4
to 530 L/sq m/d (230 to 1.8 ac/mgd) for FWS systems
and from 30 to 410 L/sq m/d (31 to 2.3 ac/mgd) for SF
systems. Limited cost data show construction costs
range from $16 to $770 per cu nVd ($0.06 to $2.90 per
gpd) for FWS systems and from $60 to $790 per cu ml
d ($0.23 to $3.00 per gpd) for SF systems. Because of
the limited data, all of these figures should be viewed
with caution.

Data collection activities performed for the Risk Re-
duction Engineering Laboratory (RREL) of the U.S. En-
vironmental Protection Agency are divided into four
categories, depending on the intended use of the data.
Quality Assurance (QA) Project Plans are written to
ensure that project needs will be met and that quality
control procedures are sufficient for obtaining data of
known quality. The level of QA required, however, de-
pends on the project category selected for a given
project. Projects that produce results for the purpose
of assessing suppositions are identified as Category IV
projects. 'Pure' research and development projects
frequently fit into the category. To assist professional
scientists and engineers in preparing QA Project
Plans, separate guidance manuals in an easy-to-read
format have been developed for each category. The
Category IV manual contains detailed descriptions of
each of the 5 required elements of a Category IV QA
Project Plan. Also included are definitions and expla-
nations of frequently used terms, examples of QA
forms and charts, sample equations and numerous
types of tables suggested for summarizing information.

The report is the product of a one-day workshop on the
diaper industry that was sponsored by the U.S. EPA.
Four topics covered during the workshop were public
hearth and safety, recycling, composting, and product
life cycle analysis. The primary objective of the work-
shop was to identify areas within the diaper industry
that need further research in order to lessen the ad-
verse impacts that diapers have on the environment.
Summaries of each of the four topics as well as sum-
maries of discussion comments and research needs
identified during the workshop are included in the
report. A large number of research ideas were generat-
ed during the workshop. These ideas included deter-
mining the health risks associated with handling dia-
pers, developing methods for improving the recyclabi-
lity of plastics used in diapers, determining where
diaper-related life cycle analysis should begin and end,
and determining the economic viability of composting.

Through the combined experience of industrialized na-
tions during the last two to three decades of environ-
mental protection, the authors have gained a critical
recognition of the limitations of the natural resources
(air, water and land) around us. The authors have seen
a continued rapid industrial development during the
last 30-40 years; however, the authors have witnessed
previous mistakes of industrialized countries being re-
peated. Such mistakes have resulted in overwhelming
environmental deficits. These environmental debts
became very obvious in many forms: the air in many in-
dustrial zones became so dirty it was deemed un-
healthy; many lakes and rivers became too polluted for
recreational use; and pesticides and other agricultural
chemicals were exerting adverse effects on wildlife. In
order to manage such crises, governmental agencies
were established throughout the world to control envi-
ronmental problems. In the United States, Congress
enacted a series of laws to clean up the pollution.
These accomplishments were very significant in light
of a tremendous increase in population and economic
growth during the same period. However, through our
experience in approaches to remove contaminants
from individual environmental media, the authors have
come to recognize that we must accord more attention
to cross-media approaches for controlling our pollution
problems. Selected examples of current efforts in pre-
vention oriented multimedia risk assessment and risk
management will be discussed to emphasize the need
for enhanced efforts in the area.

The Air Risk Information Support Center (Air RISC) has
been organized by U.S. EPA's offices of Air Quality
Planning and Standards and Health and Environmen-
tal Assessment. The center has been developed in co-
operation with the State and Territorial Air Pollution
Control Program Administrators and the Association of
Local Air Pollution Control Officials. These officials are
encouraged to contact Air RISC for assistance in ob-
taining health, exposure and risk assessment informa-
tion on toxic air pollutants. Questions may be tele-
phoned in via a Hotline and are referred to an appropri-
ate EPA expert who will attempt to provide the infor-
mation requested. EPA Health Assessment Docu-
ments, risk information databases, and other appropri-
ate sources are used to provide rapid, scientifically-
valid information. Technical assistance (defined as
more in-depth review of a particular air toxics problem)
is also provided, typically when there is no existing
health documentation on a particular air toxic or when
the requesting office needs assistance in reviewing
risk assessment information provided to it. When there
is a demonstrated need, Air RISC will provide technical
guidance in the form of documents and workshops on
health risk assessment methodology and toxicology.
In each of these forms of assistance, it is anticipated
that valuable lines of communication will be estab-
lished between air toxics control officials and the EPA
staff involved in the program.

The Clean Air Act (CAA) requires periodic review of ex-
isting criteria that form the basis for carbon monoxide
(CO) air quality standards. These air quality criteria are
to reflect the latest scientific information useful in indi-
cating the kind and extent of all identifiable effects on
public health that may be expected from the presence
of CO in ambient air. In keeping with the requirements
of the CAA, the U.S. Environmental Protection Agency
has started to review the criteria for CO. A number of
critical issues germane to the review are presented.
Additional session papers provide more detailed dis-
cussion of these issues. The paper discusses specific
health issues pertaining to: (1) mechanisms of action
of CO, particularly an evaluation of intracellular mecha-
nisms secondary to impaired oxygen delivery caused
by the formation of carboxyhemoglobin (COHb); (2) ex-
posure assessment, including an evaluation of the ac-
curacy and reliability of different methods for determin-
ing COHb; and (3) specific health effects occurring in
groups of individuals considered to be at greatest risk
to CO at ambient or near-ambient exposure levels in-
cluding a reevaluation of previous dose-response
functions for CO utilizing the information gained from
recently completed studies. These critical issues will
need to be resolved in order to determine the extent to
which adverse effects are occurring in the population,
particularly at the lower COHb levels of greatest inter-
est to standard setting.

The report identifies the MOBILE4 input variables that
can have significant impacts on highway vehicle emis-
sions inventories and gives priorities for the develop-
ment of improved guidance for specifying MOBILE4
inputs. Two major factors are considered: (1) the likeli-
hood and potential range of variability in values for
each MOBILE4 input; and (2) the potential magnitude
of the effect of these variations, in terms of impact on
typical mobile source inventories. The analysis up-
dates previous work based on MOBILES by using
MOBILE4 for the sensitivity analysis and by adding
new MOBILE4 variables. The approach used in previ-
ous work is modified to address the specific concerns
of the project-the State Implementation Plan (SIP)
and National Emissions Data System (NEDS) invento-
ry/guidance context. An additional level of detail is in-
cluded for two critical variables (speed and tempera-
ture). Sensitivity to basic vehicle inspection/mainte-
nance program specifications (waiver and compliance
rate) is also considered. The primary sensitivity analy-
sis is structured around two base cases representing
ozone and carbon monoxide (C) season conditions.
The report describes: (1) MOBILE4 input variable
values for the ozone and CO base cases, (2) the varia-
bles and ranges or alternate values applied in the sen-
sitivity analysis, (3) sensitivity analysis results, and (4)
conclusions.

The report describes a three-part study to gather infor-
mation on liquid flow through soil liners in hazardous
waste disposal facilities. In the first part of the study a
model was developed to simulate flow occurring
through discreet channels in lifts (a layer of compacted
soil) and in the horizontal layer between lifts. The
model indicated that high overall field hydraulic con-
ductivity values may result from horizontal flow be-
tween lifts. In the second part of the study, laboratory
tests using large 60-cm-diameter permeameters
showed that the conductivity to water typically in-
creased by one order of magnitude with depth in a 23-
cm-thick lift of compacted clay. Clod sizes ranging
from 2.5 to 7.5-cm had little influence on the hydraulic
conductivity. Exposure of the compacted soil to the at-
mosphere for as little as 24 hr resulted in severe crack-
ing and associated high conductivities resulting from
flow through the desiccation cracks. Bulk density was
a poor predictor of the conductivity of a compacted
soil. Dye patterns in the permeameters also indicated
flow through preferential channels and inter-clod
spaces. In the third part, field studies of a 3-lift liner re-
vealed that horizontal flow does indeed occur at the
interface between the lifts when channels penetrate
the overlying lift.

The project was initiated to investigate the effective-
ness of soil gas sampling in leak detection. Soil gas
surveys were performed at 27 active gasoline service
stations in three diverse geographic regions. Hydrocar-
bon vapor concentrations in the backfill surrounding
the underground storage tanks were sampled and
analyzed. The 27 gasoline service stations were se-
lected as non-leaking sites and the three regions were
selected for their active underground storage tank reg-
ulatory programs, as well as their differences in geolo-
gy, hydrology arid climate. A comparison was made
with contaminated site data obtained from Tracer Re-
search Corporation's historical records and significant
differences can be seen between the two distributions.
It was determined that the best approximation of total
hydrocarbon (less light aliphatics) concentrations,
based on available calibration data, was achieved
using average response factor calculated from the
daily response factors of benzene, toluene, ethylben-
zene, and ortho-xylene.

Risk assessment of mixtures of environmental pollut-
ants has become a subject of increasing public and
regulatory concern. Typically, assessment of mixtures
has been based on aggregating the risks associated
with the individual constituents of the mixture. This ap-
proach does not consider the potential synergistic and
antagonistic effects of the components, and does not
incorporate the risk associated with unidentified con-
stituents or constituents for which the individual risks
are not known. On June 7-9, 1988 the U.S. Environ-
mental Protection Agency (EPA) held an 'International
Symposium on Chemical Mixtures: Risk Assessment
and Management' in Cincinnati, OH, to provide a forum
where critical issues concerning assessment of mix-
tures could be presented and discussed. Approximate-
ly 200 scientists attended, representing a wide variety
of disciplines, institutions, and countries. During the
two-and-one-half days of the symposium, leaders in
the multidisciplinary field of risk assessment presented
state-of-the-art approaches and techniques for quanti-
fying the potential health risks from exposure to chemi-
cal mixtures. They also addressed current knowledge
in the various disciplines of risk assessment, as well as
recent developments in sources of exposure, pharma-
cology, and toxicology. The symposium was dedicated
to the memory of Dr. Jerry Strata, founder and director
of the EPA Environmental Criteria and Assessment
Office.

Current methods for estimating human health risks
from exposure to threshold-acting toxicants in water or
food, such as those established by the U.S. EPA, the
FDA, the NAS, the WHO and the FAp, consider only
chronic or lifetime exposure to individual chemicals.
These methods generally estimate a single, constant
daily intake rate which is low enough to be considered
safe or acceptable. The intake rate is termed the ac-
ceptable daily intake (ADI). Two problems with the ap-
proach have been recognized. The first problem is that
the method does not readily account for the number of
animals used to determine the appropriate 'no-qb-
served-effect-level' (NOEL). The second problem with
the current approach is that the slope of the dose-re-
sponse curve of the critical toxic effect is generally ig-
nored in estimating the ADI. The report illustrates both
a revised approach to estimate ADIs with all toxicity
data which includes methods for partial lifetime as-
sessment, and novel methods for ADI estimation with
quanta! or continuous toxicity data. The latter method
addresses to a degree the common problems with the
current approach.

The paper analyzes the performance of landfill leach-
ate collection systems with low-permeability soil liners
under steady-state conditions. Algebraic equations
and graphs are presented for predicting the average
arid maximum saturated depth on the liner, the loca-
tion of the maximum saturated depth, and the leakage
rate. The equations and graphs are developed from
numerical solutions of the governing differential equa-
tion. Some surprisingly simple relationships are shown
to be applicable over much of the practical range. In
general, saturated depth over the liner is sensitive to
four parameters: the liner slope, the drainage length or
drain spacing, the saturated hydraulic conductivity of
the drain layer, and the difference between the im-
pingement rate on the liner and the liner's hydraulic
conductivity. Under normal conditions, leakage rate is
sensitive only to the hydraulic conductivity of the liner.
Within the practical range, liner thickness has little
effect on either saturated depth or leakage rate.

Long-term simulations of 17 landfill cells from six sites
are performed using the Hydrologic Evaluation of
Landfill Performance (HELP) computer model. Results
are compared with field data from a variety of landfills
to verify the model and to identify shortcomings. The
sites are located in California, Kentucky, and Wiscon-
sin. Since site data are not available for some of the
model input parameters, default values are used in
many instances. It is found that model predictions are
generally bracketed by field measurements. Good
agreement between the predictions and measure-
ments is obtained by calibrating the hydraulic conduc-
tivity of the cover materials while staying within the
range of hydraulic conductivity values reported in the
literature for these materials. The results indicate that
the HELP model can be a very useful tool for designing
and evaluating landfills.

Recent Progress and Problems, p45-56. Presented at
the American Conference of Governmental Industrial
Hygienists, Cincinnati, OH., 1988.
Much of the initial interest in the control of pollutants,
both in the United States and abroad, focused on such
'traditional' pollutants as sulfur dioxide, paniculate
matter, Total Suspended Particulate (JSP) and partic-
ulate matter, nitrogen oxides, carbon monoxide,
ozone, and lead. While there is still substantial room
for progress in the control of some of the criteria pollut-
ants, substantial progress has been made in under-
standing the impact of these pollutants and in regulat-
ing most of them. At the same time, another new group
of pollutants has come to the forefront of the scientific
and regulatory community. These non-criteria pollut-
ants include organic compounds such as chlorinated
organics, dioxins, aldehydes, and polycyclic organic
compounds, as well as heavy metals such as cadmium
and mercury. For many of the uncommon noncriteria
pollutants, relatively little is known about their effects
on health and the environment, and many of the po-
tential effects could take decades to emerge. Similarly,
ambient air emissions of many of these substances
have not been systematically regulated in the past. Be-
cause most of the elevated exposures to these chemi-

cals were thought to occur only in the workplace,
widely divergent controls and regulations were en-
acted. Now that one realizes the pervasiveness of
these pollutants in the ambient environment, they are
grappling with ways to assess safe exposure levels to
them. Cadmium is presented as an example of a
standard-setting approach used to regulate noncriteria
pollutants.

The article (1) identifies specific combustion condi-
tions which are postulated to lead to low emission of
organics-components of good combustion practice
(GCP), (2) summarizes experimental correlations be-
tween GCP components and organic emissions, and
(3) briefly discusses strategies for applying GCP to
ensure continuous control of organic emissions. Back-
ground information on chlorinated dibenzo-p-dioxin
and -furan (CDD/CDF) formation theories is also pre-
sented and additional research needed to establish
the effectiveness of combustion strategies for control
of municipal waste combustor (MWC) organic emis-
sions is discussed. (NOTE: GCP is defined as combus-
tion conditions which lead to low emissions of trace or-
ganic pollutants.) CDD/CDF are some of the most
widely studied organic compounds of environmental
concern. EPA has announced that it intends to pro-
pose new rules for control of MWC air emissions.
Technical background studies for these rules consid-
ered the control of CDD/CDF as a surrogate for con-
trolling emission of 'MWC organics.' These studies on
the control of CDD/CDF from MWC facilities provide
useful information on strategies for controlling total or-
ganic emissions from combustion sources.

The paper presents preliminary results of performance
tests conducted at the Mid-Connecticut Refuse-de-
rived Fuel Facility in February 1989. Objectives of
these tests were to evaluate the effects of combustion
and flue gas cleaning process conditions on air pollu-
tion emissions and residue properties. A cursory analy-
sis of test results support the following tentative con-
clusions: (1) Combustor emissions of CO and PCDD/
PCDF as measured at the SDA inlet were sensitive to
the amount and distribution of OFA. Combustion air
distributions which result in poor mixing and low
excess air margins are believed to be the primary
causes of increased CO emissions. (2) PCDD/PCDF
stack emissions of < 0.40 nanpgram/standard cubic
meter were achieved at the Mid-Connecticut Facility
when good operating conditions were maintained on
both the combustion and FGC processes. (3) FF outlet
concentrations of PCDD/PCDF depend on SDA/FF
operating conditions. The lowest emissions were asso-
ciated with medium to low gas temperatures at the
SDA outlet, while the SDA lime slurry flow rate was set
to provide medium to low SO2 concentrations at the
FF outlet.

The paper discusses a new U.S. strategy to reduce
public exposure to toxic air pollutants in the ambient
air. The strategy calls for state and local authorities to
take on more of the lead regulatory role. The shift in
emphasis and responsibility prompted EPA's Offices
of Research and Development (ORD) and Air Quality
Planning and Standards (OAQPS) to develop and im-
plement an innovative technical assistance program,
called the Control Technology Center (CTC). It has
since been expanded to include technical assistance
in the areas of control of air toxics, particulate matter,
and volatile organic compounds (VOCs); emission
measurements; and other areas where expertise is
available to ORD and OAQPS. Available through the
CTC are three categories of technical assistance: tele-
phone HOTLINE calls, direct engineering assistance,
and technical guidance projects. The CTC HOTLINE is
a special telephone number that state and local agen-
cies can call for easy access to EPA personnel who
can provide prompt assistance. Engineering assist-
ance projects require more in-depth engineering analy-
sis; these projects are short-term (less than 3 months)
and specific in nature. Technical guidance projects
result from problems identified by more than one
agency; they are longer-term and of national interest.
The paper discusses five CTC projects to illustrate the
assistance provided.

The paper gives results of an evaluation of calcium
sorbents for acid gas emission control for effective-
ness in removing SO2/HCI and SO2/NOx from simu-
lated incinerator and boiler flue gases. All tests were
conducted in a bench-scale fixed-bed reactor simulat-
ing fabric filter conditions in an acid gas removal proc-
ess. Reagent grade Ca(OH)2 was used to establish
baseline sorbent performance. The reactivity of rea-
gent grade Ca(OH)2 with HCI from SO2/HC1 mixtures
gradually increased with decreasing approach to satu-
ration temperature. SO2 reactivity toward Ca(OH)2
was very sensitive to approach to saturation. Novel
calcium silicate sorbents were tested for reactivity with
both SO2 and HCI. A thermal window for optimum NOx
removal was found at 90 C when Ca(OH)2 was used at
SO2/NO ratios of 1:1. Reactivity of Ca(OH)2 toward
S02 from SO2/NO mixtures was very sensitive to ap-
proach to saturation, while reactivity with NO was in-
sensitive. Several additives were subsequently tested
to determine optimum sorbent combinations for SO2/
NO control. To date, the most promising additives are
Mg(OH)2 and Na2HPO4 at 10 mo! % concentrations.
As with SO2/HCI, calcium silicate has been shown to
be superior for SO2/NO capture. Some implications
for larger-scale process configurations and sorbent se-
lection for HCI/SO2/NO control are discussed.

A model is proposed for fish consumption advisories
based on consensus-derived risk assessment values
for common contaminants in fish and the latest risk as-
sessment methods. The model accounts in part for the
expected tpxicity to mixtures of chemicals, the underly-
ing uncertainties in the health and exposure data, and
the amount of contaminated fish consumed. Applica-
tion of the model to a larger number of chemicals is
possible. Noncancer toxicity is used as an example,
but this model is applicable for risks from cancer as
well. A second related model is proposed that is useful
for comparing potential risks among sites (e.g., rivers
and lakes). (Copyright (c) 1990 Academy Press, Inc.)

The effectiveness of landfill-liner designs is evaluated
in terms of the slope, drainage length, and saturated
hydraulic conductivity of the lateral drainage layer, the
saturated hydraulic conductivity of the soil liner, and
the fraction of the area under a synthetic liner where
leakage is occurring. The evaluation is performed
using Version 1 of the Hydrologic Evaluation of Landfill
Performance (HELP) model. The effectiveness is
quantified by comparing the lateral drainage rate to the
vertical percolation rate expressed as percentages of
the total inflow. The two multiple-liner systems speci-
fied in the Hazardous and Solid Waste Amendments
(HSWA) minimum technology guidance are shown to
have different leakage-detection characteristics. One
system detects significant leakage before leakage per-
colates out of the landfill, whereas the other system
detects leakage only after significant leakage perco-
lates out of the landfill. Four other designs were also
examined-two with single liners and two with double
liners. The two HSWA designs detected leakage at
lower synthetic-liner-leakage fractions, but all designs
with composite liners were nearly equally effective in
reducing leakage from landfills. (Copyright (c) 1990,

Analyses of soil gas compositions and stable and ra-
dioactive carbon isotopes in the vadose zone above
an alluvial aquifer were conducted at an organic sol-
vent disposal site in southeast Phoenix, AZ. The study
investigated the source and movement of carbon diox-
ide above a plume of organic solvent contamination.
Two soil gas monitor wells, each screened and grout-
ed at four discrete depths above the water table, pro-
vided sampling access. One well penetrated the un-
contaminated vadose zone, the other penetrated a
contaminated area now covered with asphalt. Carbon
dioxide concentrations in the uncontaminated area
range from 1.45% at 8 ft to 3% at 19 ft below land sur-
face. Isotopic evidence suggests root respiration and
minor oxidation of organic matter as C02 sources at
this site. Carbon dioxide in soil gas samples from the
contaminated area exceeded 15% while O2 levels
were as low as 1%. Carbon dioxide concentrations
and carbon isotope values are consistent with in situ
aerobic biodegradation of the organic pollutants.

The magnitudes of pulmonary responses the authors
previously observed (1) following 6.6-h exposure to
0.12 ppm ozone (OS) suggested that responses would
also occur with similar exposures at lower O3 concen-
trations. The objective of the study was to determine
the extent of pulmonary function decrements, respira-
tory discomfort, and increased airway reactivity to
methacholine induced by exposure to O3 below 0.12
ppm. Separate 6.6-h chamber exposures to 0.00,0.08,
0.10, and 0.12 ppm O3 included six 50-min periods of
moderate exercise (VE = 39 L/min, HR = 115 bpm,
and VO2 = 1.5 L/min). Each exercise period was fol-
lowed by 10 min of rest A 35-min lunch break was in-
cluded midway through the exposure. Although not in-
tended as an exact simulation, the overall duration, in-
tensity, and metabolic requirements of the exercise
performed were representative of a day of moderate to
heavy work or play. Preexposure FEV, averaged 4.39
L, and essentially no change (+0.03 L) occurred with
exposure to 0.00 ppm O3. Significant decreases
(p<0.01) of -0.31, -0.30, and -0.54 L were observed
with exposures to 0.08, 0.10, and 0.12 ppm, respec-
tively. The study concludes that exposure to O3 at
levels often found in ambient air while engaged in ac-
tivity representative of a typical day of moderate to
heavy work or play induced clinically meaningful pul-
monary responses.

The paper gives results of measurements of metal par-
titioning between the fine condensation aerosol and
the larger particles produced during rapid heating of
polydisperse droplet streams of aqueous solutions
containing nitrates of Cd, Pb, and Ni in a laboratory-
scale furnace. Trimodal particle size distributions were
observed. Partitioning of the larger particles between
residual and intermediate modes is consistent with the
dependence of particle porosity on condensed phase
transformations during nitrate decomposition. In addi-
tion, ultrafine particles were produced. In the Ni tests,
where vaporization is not a reasonable mechanism for
inorganic aerosol formation over the range of tempera-
tures studied (900-1500 K), 30-35% pf the particles
had aerodynamic diameters of<1 micrometer. Fur-
thermore, a preponderance of cenospheres was ob-
served in the large particle size fractions. It is conjec-
tured that the NiO cenospheres form and burst to
produce the submicron particles. In the Ca and Pb ex-
periments, the amount of submicron particles pro-
duced was in qualitative agreement with the amount
calculated for the time-dependent vaporization of the
thermodynamically dominant monoxide species. How-
ever, two findings suggest that fragmentation contrib-
uted to submicron particle formation in these tests as
well.

An integrated Fate Model has been developed for pre-
dicting the fate of organics in a wastewater treatment
plant. The Fate Model has been validated using experi-
mental data from a pilot-scale facility. The biodegrada-
tion kinetic constants for some compounds in the Fate
Model were estimated using the group contribution ap-
proach. The Fate Model has been compared with
other existing models in the literature. Potential appli-
cations of the Fate Model include assessment of vola-
tile organic compound (VOC) emissions from a
wastewater treatment plant, evaluate pretreatment re-
quirements prior to discharge to the sewer system,
predict concentrations of toxic compounds on sludges,
and provide a general framework for estimating the re-
moval of toxic compounds during activated sludge
treatment.

sponses to the six alcohols all showed similar bimodal
responses characterized by a threshold dose below
which no change in body temperature occurred, and a
suprathreshold regression with increasing dose caus-
ing greater hypothermia. Relative efficacy of the alco-
hols was compared using both the threshold dose to
cause hypothermia and the dose which would cause
body temperature to decrease by 1 C. Both measures
gave the progression of toxicity from least to most
potent of: methanol < ethanol <2-propanol<1-propa-
nol < 2-butanol < 1-butanol. The effective dose of an
alcohol was compared to its membrane/buffer parti-
tion coefficient (P(sub m/b)), and there was a high in-
verse-correlation between the hypothermic dose of an
alcohol and its lipid solubility.

Commonly used experimental mammals, such as the
rat and mouse, exhibit hypothermia and hypometabc-
lism when exposed acutely to many drugs and other
chemical substances. This toxic-induced hypothermic/
hypometabolic state may be an inherently protective
response that can reduce the lethality of a toxic insult.
However, as body mass increases, the ability to lower
body temperature in response to toxic insult is dimin-
ished. Hence, the presence of a protective hypometa-
bolic/hypothermic response in small laboratory mam-
mals and apparent lack thereof in larger species, such
as humans, may represent an additional physiological
dissimilarity which may underestimate the risk assess-
ment of acute lexicological data.

The direction of epoxide ring opening may be predict-
ed using the techniques of theoretical chemistry by
comparing the computed total energy of the two possi-
ble carbocations formed. To predict the direction of
epoxide ring opening and the potential binding of
aceanthrylene 1,2-epoxide to biopolymers, quantum
mechanical calculations were performed on the two
potential hydroxy carbocations. The 2-hydroxy carbo-
cation (II) was favored over the 1 -hydroxy carbocation
by 11.8 kcal/mol. Molecule II had more positive charge
at the meso carbon group than at the nominally elec-
trostatic potential confirm this result, and indicate the
possibility of unusual adducts to biopolymers. Similar
calculations on the equivalent epoxides of acenaph-
thylene and acephenanthrylene do not show the same
results. Modeling the addition products of II with small

products do not form, and that the interaction is con-

The organochlorine pesticide, pentachlorophenol
(PCP), a potent sulfotransferase inhibitor, reduces
binding of the hepatocarcinogen, 2,6-dinitrotoluene
(DNT), to hepatic DNA by 95% after a single i.p. injec-
tion. Activation of DNT to genotoxic metabolites in-
volves enzymes in both the liver and the intestinal
flora. Since PCP also has bactericidal activity and in-
duces hepatic mixed function oxidase activity after
longer treatment, the effect of PCP on intestinal
enzyme activity and the biotransformation of DNT to
genotoxic metabolites, after 1, 2, 4, and 5 weeks of
treatment, was studied. Male Fischer 344 rats were
dosed daily, by gavage, with either 20 mg/kg PCP or
the peanut oil vehicle. After 1,2,4, and 5 weeks, select
control and treated animals were injected P.O. with 75
mg/kg 2,6-dinitrotoluene and transferred to metabo-
lism cages, where urine was collected and tested for
mutagenic activity. At 2 and 4 weeks, 6 control and 6
treated animals were sacrificed and nitroreductase,
azo reductase, beta-glucuronidase, dechlorinase and
dehydrochlorinase activities were analyzed in homog-
enates of the small intestine, large intestine, and
cecum. At 5 weeks, hepatic DNA adduct formation
was assayed by the (32)P-postlabeling of DNA. Re-
sults of the study indicated that PCP accelerated the
biotransformation of DNT to genotoxic metabolites
and potentiated the formation of DNT - induced DNA
adducts in the liver.

The purpose of the study was to assess the effect of
genetic strain on the acute and long-term thermoregu-
latory response to the neurotoxicant, trimethyltin
(TMT) in rats of the Long-Evans (LE) and Fischer 344
(FCH) strains. In one study basic thermoregulatory re-
sponses including colonic temperature (Tc), metabolic
rate (MR), evaporative water loss (EWL), motor activity
(MA), and thermal conductance (Cd) were measured in
both rat strains at ambient temperatures (Ta) of 10, 28,
and 37 C. It was found that the LE rat has a significant-
ly higher Tc when it is measured in their home cage.
Because of its smaller mass the FCH rat has a higher
MR at all Ta's. The FCH rat also has a greater rate of
EWL during exposure to a Ta of 37 C. Following i.v. ad-
ministration of 8.0 mg/kg TMT both rat strains become
significantly hypothermic; however, the effect differed
significantly between the strains. At 26 to 34 days after
TMT exposure thermoregulatory responses at Ta's of
10 to 37 C were generally similar to that of the saline
controls. However, there was a significant elevation in
MR and MA of the TMT-treated FCH rat which merits
further study. Overall, it appears that autonomic ther-
moregulatory responses measured 26 to 34 days after
TMT are near normal in the FCH and LE rat strains.

Ethane dimethanesulphonate (EDS) is well-recognized
as a Leydig cell toxicant. Although this compound has
been studied extensively to date, certain toxicological
criteria have not been met. For instance, the dose-re-
sponsiveness of Leydig cells to EDS, both in vitro and
in vivo, is not well established. In addition, the data re-
garding the cellular site of action of EDS during Leydig
cell toxicity and the status of Leydig cell viability during
the affected period remains controversial. The study
used both highly purified (98 %) and interstitial (14 %)
Leydig cell preparations to determine the in vitro EC50
(370 micro M) and in vivio (sub 50) (60 mg/kg) for
hCG-stimulated testosterone (T) production, respec-
tively. Leydig cells were recovered in approximately
equal number following all in vivo and in vitro EDS ex-
posures. Test results indicate that when Leydig cells
are exposed to EDS either in vitro or in vivo, the bio-
synthesis of T is compromised between the production
of cyclic adenosine monophosphate (CAMP) activa-
tion of protein kinase and the cholesterol side chain
cleavage enzyme.

The flash evoked potential (FEP) of rats has a large
negative peak (N(sub 160)) approximately 160 msec
following stimulation. The peak has been reported to
be modulated by the subject's state of behavioral
arousal and influenced by several test parameters.
These experiments examine the influences of repeat-
ed testing, the number of stimuli/session, interaction
of ambient illumination and flash intensity, and the
effect of pupillary dilation on the development and am-
plitude of peak N(sub 160). The amplitude of peak
N(sub 160) increased with daily testing, and reached
an asymptotic amplitude by about day 10. This ampli-
tude was affected by the intensity of the flash stimulus
relative to the ambient illumination (RFI), and ap-
peared to reach a ceiling amplitude at greater than 50
dB RFI. The number of stimuli/session and dilation of
the subject's pupils did not have a large influence on
the growth or asymptotic level of peak N(sub 160) am-
plitude. The data are consistent with the hypothesis
that the growth of peak N(sub 160) may represent a
sensitization-like phenomenon.

Groups of male B6C3F mice (N=50) were provided
drinking water containing 2 g/liter sodium chloride
(control) and 0.05, 0.5 and 5 g/liter dichloroacetic acid
(DCA). Treatment of 30 animals in each group was car-
ried out to 60 or 75 weeks. In a separate experiment,
mice exposed to 3.5 g/liter DCA and the correspond-
ing acetic acid control group were killed at 60 weeks.
Groups of 5 mice were killed at 4,15,30 and 45 weeks.
Time=weighted mean daily doses of 7.6, 77,410, and
486 mg/kg/day were calculated for 0.05,0.5, 3.5, and
5 g/liter DCA treatments. Animals exposed to 3.5 and
5 g/liter DCA had final body weights that were 87 and
83%, respectively of the control value. Relative liver
weights of 136, 230, and 351% of the control value
were measured for 0.5, 3.5 and 5 g/liter, respectively.
At 60 weeks mice receiving 5.0 g/liter DCA had a 90%
prevalence of liver neoplasia with a mean multiplicity
of 4.50 tumors/animal. Exposure to 3.5 g/liter DCA for
60 weeks resulted in a 100% tumor prevalence with an
average of 4.0 tumors/animal. No liver tumors were
found in the group treated with acetic acid. Hyperplas-
tic nodules were seen in the 3.5 (58%; 0.92/animal)
and 5 g/liter DCA groups (83%; 1.27/animal).

Previous work has shown that chlordecone (CD)-am-
plified CCI4 hepatoxicity and lethality can be mitigated
by pretreatment with (+)-cyanidanol. These studies
also revealed that stimulated hepatocellular regenera-
tion might play an important role in the cyanidanol pro-
tection of CD-amplified CCI4 toxicity. The present stud-
ies conducted over a time course of 0 to 120 hr after
CCI4 challenge describe sequential changes in hepat-
ic (3)H-thymidine incorporation into hepatocellular nu-
clear DNA, polyamines and related enzymes, and his-
tomorphometry of liver sections from variously treated
rats. Male Sprague-Dawley rats (125-150 g) were
maintained on a control diet or on a diet contaminated
with CD (10 ppm for 15 days) and/or pretreated with
cyanidanol (250 mg/kg, ip) at 48, 24 and 2 hr before a
single ip injection of 50 microliter CCI4/kg(L) to 100 mi-
croliter CCI4/kg(H) on day 16 of the dietary protocol.
Cyanidanol-stimulated (3)H-thymidine incorporation
was highly suppressed in rats receiving the CD +
CCI4(H) combination treatment up to 36 hr, but after
this time point a marked increase was observed. Hepa-
tocellular regeneration, quantified histomorphometri-

gressively increased in rats protected from CD + CCI4

Nuclei isolated from spermatozoa of various species
(golden hamster, mouse, human, rooster, and the fissh
tilapia) were heated at 50 -125 deg for 20-120 min and
then microinjected into hamster oocytes to determine
whether they could decondense and develop into
pronuctei. Mature, mammalian sperm nuclei, which are
stabilized by protamine disulfide bonds, were moder-
ately heat resistance. For example, they remained ca-
pable of pronucleus formation even after pretreatment
for 30 min at 90 C. Indeed, a temperature of 125 C
(steam) was required to inactivate hamster sperm
nuclei completely. On the other hand, nuclei of rooster
and tilapia spermatozoa and those of immature ham-
ster and mouse spermatozoa, which are not stabilized
by protamine disulfide bonds, were sensitive to heat-
ing; although some of them decondensed after expo-
sure to 90 C, none formed male pronuclei. Further-
more, nuclei of mature hamster sperm became heat
labile when they were pretreated with dithiothreitol to
reduce their protamine disulfide bonds. These obser-
vations suggest that the thermostability shown by the
nuclei of mature spermatozoa of eutherian mammals
is related to disulfide cross-linking of sperm prat-
amines.

In other systems such as the hypotnalamus and hippo-
campus, it has been shown that cells postsynaptic with
respect to glutamatergic inputs degenerate when ex-
posed to large doses of glutamate ('glutamate neuro-
toxicrty'). Studies show that large doses of glutamate
administered intraperitoneally are toxic to spiral gangli-
on cells in the inner ear of the rat The present study in-
vestigated whether similar levels of glutamate cause
alterations in the neurons of the cochlear nuclei. Spe-
cifically, the study investigated morphology and size of
the cochlear nuclear complex and its subdivisions as
well as the size and density of cochlear nucleus neu-
rons following administration of glutamate. The mor-
phological evidence indicates that glutamate caused
severe anatomical alteration of the cochlear nuclei.
The changes were most pronounced in the anteroven-
tral cochlear nucleus, especially in the neurons that re-
ceive terminals of the end bulbs of Held from the coch-
lear nerve. This could be a direct effect of glutamate in
the cochlear nuclei or secondary to degeneration of
cochlear nerve fibers in the inner ear. (Copyright (c)

Experimental and theoretical evidence pertaining to
cytotoxic and genotoxic activity of paracetamol in bio-
logical systems was used to formulate a simple
mechanistic hypothesis to explain the relative inhibi-
tion of replicative DNA synthesis by a series of 19
structurally similar paracetamol analogues, 5 of which
were specifically analyzed for the current study. It was
hypothesized that the observed activity variation of the
paracetamol analogues was based on the relative
abilities of these compounds to undergo H atom loss
at the phenolic oxygen, and on the relative stabilities of
the resulting free-radical species. Three calculated pa-
rameters were found to be relevant-the partial atomic
charge on the ring carbon attached to the phenolic
oxygen, the partial charge on the phenoxy radical
oxygen, and the energy difference between the parent
phenolic paracetamol analogue and the corresponding
radical dissociation products. The variation in parame-
ter values was significantly correlated with the relative
inhibition of DNA synthesis and was easily rationalized
in terms of the mechanistic hypothesis proposed.
More specifically, competive reaction with a tyrosyl
radical species involving the transfer of a hydrogen
atom at the active site of ribonucleotide reductase was
suggested as the underlying mechanistic basis for the
observed activity variation of the paracetamol ana-
logues. (Copyright (c) 1991 by the American Chemical

The efficacy of inhalation therapy may be improved by
the selective deposition of aerosolized medicines, by
explicitly targeting and delivering drugs to prescribed
lung sites. Here, the deposition patterns of test aero-
sols, mapped in surrogate respiratory tracts consisting
of replica laryngeal casts and fabricated tracheobron-
chial models, are analyzed. Particles were preferential-
ly deposited at bifurcations, specifically at carinal
ridges. Evidence from other investigations indicates
that mucociliary clearance may be impeded at such
sites in vivo. When these two effects are coupled, the
findings suggest that epithelial cells and receptors at
airway branching sites may receive concentrated
doses of inhaled pharmacological agents. To focus the
effects of airborne drugs the lung should, therefore, be
considered as a serial network of Y-shaped bifurcation
units. The findings have important implications to aero-
sol therapy protocols including: (1) the treatment of
bronchogenic carcinomas because malignant tumors
have a predilection for upper airway bifurcations; and
(2) lung diseases related to the afferent nervous
system since components of neural pathways frequent
such locations.

A series of experiments was conducted to assess the
comparability of physiological processes in rat and
human visual systems. In the first set of experiments,
transient visual evoked potentials (VEPs) were elicited
by the onset of sine-wave gratings of various spatial
frequencies. The spatial frequency-response profiles
of the first positive and immediately succeeding nega-
tive components differed from one another, but were
similar in the two species. In addition, amplitude of the
negative, but not the positive, component was strongly
attenuated in both species following stationary pattern
adaptation. In the second set of experiments, steady-
state VEPs were elicited by the onset and offset of the
gratings. The spatial frequency profiles of the 1F (re-
sponse amplitude at the frequency of stimulus onset-
offset) and 2F response components differed from one
another, put were similar in both species. The final set
of experiments indicated that diazepam, a GABA
agonist, reduced amplitude of 2F, but not 1F, in both
species.

Due to the ubiquitous presence of p-xylene in air and
the existing uncertainty regarding its hepatotoxic po-
tential, the authors examined the effect of acute and
short-term exposure to inhaled p-xylene on the liver.
Male F-344 rats were exposed to 0 or to 1600 ppm p-
xylene, 6 h/d, for 1 or 3 d. Exposure to inhaled p-
xylene caused no histopathological evidence of hepat-
ic damage and had little or no effect on the serum
levels of aspartate aminotransferase, alanine amino-
transferase, lactate dehydrogenase, ornithine carba-
myl transferase, alkaline phosphatase, and total biliru-
bin. Exposure to p-xylene for 1 or 3 d resulted in an in-
crease in relative liver weight on d 1 post-exposure.
The concentration of hepatic cytochrome P-450 was
increased by both p-xylene exposure regimens on d 1
postexposure and had returned to control levels by d 3
following the single p-xylene exposure and by d 2 fol-
lowing the 3-d exposure. These observations provide
consistent evidence that acute and short-term expo-
sure to 1600 ppm p-xylene by inhalation did not
produce overt hepatotoxicity but resulted in a signifi-
cant increase in the concentration of hepatic cytoch-
rome P-450, the principal enzyme system involved in
the metabolic biotransformation of xenobiotics. (Copy-

Three sets of combustion emissions were selected for
evaluation: automotive diesel exhaust, woodsmoke,
and a coal combustion emission. Each sample was
tested in the Salmonella mutagenicity assay according
to standard protocol (plate incorporation) and spiral
assay techniques. Two assays demonstrated the fol-
lowing: (1) Diesel exhaust was generally the most mu-
tagenically potent sample in both assays. (2) Samples
were more mutagenic on rev/microgram basis in the
spiral assay, especially when metabolic activation was
added. (3) The spiral assay required 1 /20 the sample
mass of the standard assay to test equivalent doses.
(4) Dichloromethane extracts of the complex mixtures
could be tested for mutagenicity in the spiral assay.

The effects of amygdaloid kindling on Ca(2+)/Calmo-
dulin (CaM)-dependent protein phosphorylation were
assessed using one- and two-dimensional gel electro-
phoresis. In vitro phosphorylation of membrane and
cytosol fractions in the presence or absence of
Ca(2+)/CaM did not differentiate between kindled
and non-kindled amygdaloid tissue. The results sug-
gest that changes in Ca(2+)/CaM-dependent phos-
phorylation are not related to the mechanism(s) under-
lying the establishment of an amygdaloid kindled
focus.

the development of ecology databases and the cali-
bration of test protocols for genetically engineered
microorganism (GEM) risk assessments. Data ob-
tained from GEMs mesocosm testing would provide a
critical knowledge base for regulation of environmental
releases of GEMs. Workshop presentations covered
the positive and negative design features of specific
microcosm and mesocosm systems that are currently
being used in biotechnology and other kinds of re-
search. Information from these presentations was
used as the basis for design of a hypothetical meso-
cosm chamber that would meet appropriate contain-
ment and environmental control needs. The meso-
cosm was designed to support regulatory initiatives. It
was not conceived to serve as a standard procedural
tool mandated by regulatory agencies for evaluating
risk assessments.

The manual describes a two-dimensional finite ele-
ment model for coupled multiphase flow and multicom-
ponent transport in planar or radially symmetric vertical
sections. Flow and transport of three fluid phases, in-
cluding water, nonaqueous phase liquid (NAPL), and
gas are considered by the program. The program can
simulate flow only or coupled flow and transport. The
flow module can be used to analyze two phases, water
and NAPL, with the gas phase held at constant pres-
sure, or explicit three-phase flow of water, NAPL, and
gas at various pressures. The transport module can
handle up to five components which partition among
water, NAPL, gas and solid phases assuming either
local equilibrium or first-order mass transfer. Three
phase permeability-saturation-capillary pressure rela-
tions are defined by an extension of the van Genuch-
ten model. The governing equations are solved using
an efficient upstream-weighted finite element scheme.
The report describes the required inputs for flow analy-
sis and transport analysis. Time dependent boundary
conditions for flow and transport analysis can be han-
dled by the program and are described in the report.
Detailed instructions for creating data files needed to
run the program and example input and output files are
given in appendices.

In July and August 1988, the Illinois Environmental
Protection Agency conducted an intensive stream
quality survey of the lower Big Muddy River main stem.
The survey focused on water quality, fish populations,
contaminants in fish, instream habitat, and sediment
chemistry in a 104-mile segment of the Big Muddy
River between Rend Lake and the Mississippi River.
The Big- Muddy main stem survey was designed to
assess stream quality in the vicinity of mine drainage
sources and major municipal point source dischargers.
A major objective of the project was to identify sources
of acid mine drainage contributing to water quality deg-
radation and fish kills in the Big Muddy River upstream
from the public water supply intake at Royalton, Illinois.
EPA staff successfully identified two abandoned
mines believed to be the major sources of mine-relat-
ed water quality problems in the Big Muddy River in the
vicinity of the Royalton. Water quality samples collect-
ed in summer 1988 at 14 main stem sites indicated Big
Muddy River water quality was considered between
fair/good and was generally not significantly impacted
by point source dischargers. Main stem biotic integrity
evaluated from fish population sampling at six sites
was considered fair.

In the report, indoor concentration data are presented
for the following general categories of air pollutants:
radon-222, environmental tobacco smoke (ETS), as-
bestos, gas phase organic compounds, formaldehyde,
polycyclic aromatic hydrocarbons (PAH), pesticides,
and inorganic compounds. These pollutants are either
known or suspect carcinogens (i.e., radon-222, asbes-
tos) or more complex mixtures or classes of com-
pounds which contain known or suspect carcinogens.
Concentration data for individual carcinogenic com-
pounds in complex mixtures are usually far from com-
plete. The data presented for complex mixtures often
include compounds which are not carcinogenic or for
which data are insufficient to evaluate carcinogenicity.
Their inclusion is justified, however, by the possibility
that further work may show them to be carcinogens,
cocarcinogens, initiators or promotors, or that they

The U.S. Environmental Protection Agency is interest-
ed in field screening hazardous waste sites for con-
taminants in the soil and surface and ground water.
The study is an initial technical overview of the princi-
pal molecular spectroscopic techniques and instru-
mentation currently available for field screening. The
goal has been to describe the power and utility of mo-
lecular (optical) spectroscopic techniques for hazard-
ous waste site screening and to define the main
strengths, weaknesses, and applications of each
major spectroscopic technique. A brief discussion is
also given for some other techniques that rely on spec-
troscopic detection: cotorimetry and fluorometry, as
well as immunoassay and fiber-optic chemical sen-
sors. The cost of instrumentation and analysis and the
time requirements are briefly discussed. Broad guide-
lines are provided for the three categories of instru-
mentation: portable, field-deployable and semi-field-
deployable. An outline of the spectroscopic principles
and instrumentation for each particular spectroscopic
techniques is given along with a description of state-of-
the-art approaches. Advantages, limitations, sensitivi-
ties and examples of specific techniques and their ap-
plications to environmental contaminants are also dis-
cussed.

The project has been designed to provide large, out-
door enclosures (terrecosms) for use in evaluating the
risk assessment methodology used by the US EPA.
These enclosures have been designed to permit test-
ing effects of insecticide applications on non-target
populations (voles) existing in nearly natural condi-
tions. The study is necessitated because recent evi-
dence indicates that the existing method (the quotient
method, which compares an organism's exposure
level to the level of hazard observed at that exposure
level) has failed to anticipate ecological damage re-
sulting from insecticide applications. As a result, EPA's
Office of Pesticides and Toxic Substances (OPTS) has
requested assistance from EPA's Environmental Re-
search Laboratory in Corvallis, OR (ERL-C) in field vali-

EPA PUBLICATIONS BIBLIOGRAPHY
Statistical methods of estimating concentration values
for use in human exposure estimates have become in-
creasingly more popular because of the complexities
in correlating the temporal and spatial concentration
variations within microenvironments with the location
of people. The number of variables and their associat-
ed uncertainty make deterministic models difficult to
use. Monte-Carlo simulations of exposure conducted
thus far have made no provision for serial correlation
effects, and therefore tend to underestimate the high-
est exposures and overestimate the lowest exposures.
The purpose of the sensitivity study is to quantify the
factors affecting serial correlation in the indoor mi-
croenvironments. Further, the authors investigate in a
very preliminary way use of personal exposure moni-
toring data to infer the value of variables needed to es-
timate indoor concentrations such as the rates of air
exchange, pollutant removal, and pollutant generation.
The authors conclude that the use of personal expo-
sure monitoring data to derive rate constants may be
useful for order of magnitude estimates.

A partial building bake-out was performed in U.S.
EPA's new Region IX Headquarters' Building in San
Francisco, California in July, 1990. The intent of the
bake-out was to reduce indoor air contaminant con-
centrations associated with residual volatile organic
compounds (VOCs) found in a variety of common
building materials and finishing agents. Four nearly
identical floors from the 21 story office building were
heated above 30 C for 34, 38, 54, and 86 hours to de-
termine the effect of bake-out duration on post-bake
pollutant concentrations. VOC and aldehyde sampling
was conducted before, during, and after the bake-out.
The results indicate that total volatile organic com-
pound (TVOC) source strengths were reduced during
the bake-out by 45-76%. Similar reductions in targeted
VOC source strengths were also observed from the
pre-to post-bake monitoring periods. While the most
abundant aldehyde species concentrations increased
approximately 65% during the mid-bake monitoring
period, post-bake aldehyde concentrations remained
similar to pre-bake levels.

General Metals Works PS-1 PUF air samplers and an
analytical method based on high resolution gas chro-
matography - high resolution mass spectrometry
(HRGC-HRMS) were evaluated for determination of
polychlorinated dibenzo-p-dioxins and dibenzofurans
(PCDDs/PCDFs) and polybrominated dibenzo-p-diox-
ins and dibenzofurans (PBDDs/PBDFs) in ambient air.
Dilute solutions of these compounds and 13C12-1234-
TCDD were used to spike the filters of PS-1 air sam-
plers which were then operated 24 hours to sample
350-400 cu m ambient air. After sampling, each quartz-
fiber filter and polyurethane foam (PUF) were spiked
with 13C12-labeled PCDD, PCDF, PBDD, and PBDF
internal standards before separate Spxhlet extractions
with benzene. The extracts were subjected to clean-up
procedures using microcolumns of silica gel, alumina
and carbon and then analyzed by HRGC-HRMS. Re-
sults derived from this study satisfied QA/QC require-
ments for analytical data and demonstrated that the
methodology could accurately determine pg/cu m and
sub-pg/cu m levels of these compounds in ambient
air. Background levels detected in ambient air are also
discussed.

The paper describes the development of climatologi-
cal information products to support ecological data
collection and analysis. Characteristics of climatologi-
cal persistence and recurrence that are critical to New
England forest health and productivity are identified.
The appropriate data are assembled and presenta-
tions developed which address specific issues perti-
nent to climate change research; background (status
and persistence); most recent decade (short-term
trends); and near-term impacts (modeling and predic-
tion). A Geographic Information System (GIS) is used
for presentation, data management and analysis. Pre-
liminary results of the research have been incorporat-
ed in United States Department of Agriculture Forest
Service monitoring program reports. The application of
regional climate research techniques to assessment
and integrated activities of the Environmental Protec-
tion Agency (EPA) Environmental Monitoring and As-
sessment Program (EMAP) is being actively explored.
Its future use in climate/forest integrated modeling is
anticipated.

Ten innovative technologies for thermally destroying
hazardous wastes were selected and described in the
paper. These technologies were either supported by
EPA's RCRA or SARA programs or developed by in-
dustry since 1980. Two of the important criteria used in
selecting these technologies are that they are (or had
been) at least at the stage of pilot-scale demonstration
and appear to be promising in terms of destruction ef-
fectiveness. The 10 technologies are: Oxygen-En-

Ozone is known to induce lipid peroxidation of lung
tissue, although no direct evidence of free radical for-
mation has been reported. The study used the electron
paramagnetic resonance (EPR) spin-trapping tech-
nique to search for free radicals produced in vivo by
ozone exposure. The spin trap alpha-(4-pyridyl 1-
oxkte)-N-tert-butylnitrone (4-POBN) was administered
i.p. to male Sprague-Dawley rats. The rats were then
exposed for 2 hrs to either 0, 0.5, 1.0, 1.5 or 2.0 ppm
ozone with 8% CO2 to increase their respiratory rate.
A 6-line 4-POBN/radical spin adduct signal a(sup
N)=15.02 G and afsup H)beta-3.27 G) was detected
by EPR spectroscopy in lipid extracts from lungs of
rats treated with 4-POBN and then exposed to ozone.
Only a very weak signal was observed in the corre-
sponding solution from rats exposed to 0 ppm ozone
(air with CO2 only). The concentration of the radical
adduct increased as a function of ozone concentra-
tion. After administration of 4-POBN, rats were ex-
posed for either 0.5,1.0,2.0 or 4.0 hrs to either 0 or 2.0
ppm ozone (with CO2). These results demonstrate
that ozone induces the production of free radicals in
rat lungs during inhalation exposure and that radical
production may be involved in the induction of lung
edema by ozone.

Pulmonary function tests are tools available to the re-
searcher and clinician to evaluate the ability of the lung
to perform its essential function of gas exchange. To
meet this principal function, the lung needs to operate
efficiently with minimal mechanical work as well as
provide an optimally minimal barrier to diffusion. Tests
of lung function permit the nondestructive assessment
of a continuum of lung performance, a continuum that
may be influenced temporarily or permanently by in-
flammatory events or structural alterations. In theory,
any function test conducted in human subjects can be
applied to animals and largely interpreted in the same
manner. Fortunately, those physiologic principles that
form the basis for clinical assessments of function
seem to apply to animals in a quantitative as well as
qualitative manner. Nevertheless, being aware of the
species differences and technical pitfalls is critical to
the ultimate interpretation of the tests, especially when
comparing them to their human analogues in health
and disease. The test described in the paper will be
useful to OAQPS and ECAO as a resource tool for
analyzing toxicotogical data from animals for use in
regulatory procedures.

The 1986 amendments to the Safe Drinking Water Act
require the U. S. Environmental Protection Agency
(EPA) to promulgate primary drinking water regulations
(1) specifying criteria under which filtration would be
required, (2) requiring disinfection as a treatment tech-
nique for all public water systems, and (3) establishing
maximum contaminant levels or treatment require-
ments for control of Giardia lamblia, viruses Legionella
spp., heterotrophic plate count bacteria, and turbidity.
EPA has promulgated treatment technique require-
ments to fulfill the Safe Drinking Water Act require-
ment for system using surface waters and groundwat-
ers under the direct influence of surface water (Federal
Register, 1969). Additional regulations specifying dis-
infection requirements for systems using groundwater
sources not under the direct influence of surface water
will be proposed and promulgated at a later date. A
model has been developed that relates pH, tempera-
ture, chlorine concentration, and inactivation level to
Giardia inactivation by free chlorine. It was found that
C times T (the product of disinfectant concentration
(milligram per liter) and disinfectant contact (minutes)
values increased with level of inactivation, disinfectant
concentration and pH and decreased with tempera-

The paper reviews principles involved in the processes
commonly used to filter drinking water for public water
systems. The most common approach is to chemically
pretreat water and filter it through a deep (2-112 to 3 ft)
bed of granular media (coal or sand or combinations of
these). The process may involve coagulation and filtra-
tion; coagulation, flocculation and filtration; or coagula-
tion, flocculation, sedimentation and filtration. In any
case, pretreatment with coagulant chemical is neces-
sary, because particle removal occurs through the
mechanism of attachment to grains of filtering materi-
al. In contrast, in typical diatomaceous earth filtration
practice, coagulant is not used and particle removal by
straining is an important aspect of the process. Slow
sand filters are used to treat high quality water. No pre-
treatment coagulants are used, but a biological popu-
lation develops in the 3 to 4 foot deep sand filter and
removal by predation and attachment to sand surfaces
and the top slimy layer above the sand (schmutz-
decke) cause the quality improvement in the process.

The composition of municipal solid waste is quite het-
erogeneous. This mixed composition results in the
presence of a variety of microorganisms that reach
densities which are relatively high, and which remain
high even after many years in a landfill. Microorganism
densities in the air at municipal solid waste processing
plants tend to be higher than levels near wastewater
treatment facilities. This may be due to indoor oper-
ations. Composting can inactivate essentially all of the
microorganisms associated with fecal matter, but ther-
mophilic fungi may cause adverse health problems.
The presence of microorganisms in municipal solid
waste does not mean that there is a high risk of infec-
tion or disease if a person is occupationally exposed to
the waste. Dose-response relationships with various
microorganisms have shown that a relatively large
number of microbes are necessary to initiate an infec-
tion or cause disease.

Over the last two years, the laboratory and others have
identified mono-, di-, and trichloro- acetic acids as
major byproducts of drinking water disinfection. In
areas of the country where relatively high levels of bro-
mine ion are naturally present in the source water, it is
expected that significant amounts of the correspond-
ing bromo and mixed chloro-bromo acetic acids will be
formed. While developing an automated GC/MS pro-
cedure to 'screen' for both previously identified disin-
fection byproducts as well as the haloacetic acids it
was discovered that reference mass spectra for 4 of
the 9 possible chloro/bromo acetic acids (as their
methyl esters) were unavailable. The paper presents
experimental reference spectra for the methyl esters
of the four acids mentioned above. All nine acids were
synthesized in-situ by reacting an aqueous solution of
phenol with chlorine in the presence of various
amounts of bromide ion.

The Safe Drinking Water Act (SDWA) of 1974 requires
that the U. S. Environmental Protection Agency
(USEPA) establish maximum contaminant levels
(MCLs) for each contaminant which may have an ad-
verse effect on the health of persons. The SDWA
clearly specifies that these MCLs shall be met at the
consumers tap. Nevertheless most regulatory concern
has been focused on water as it leaves the treatment
plant before entering the distribution system. There is,
however, growing interest in determining the factors
that cause water quality variation in drinking water dis-
tribution systems. In order to study the effort, the
Drinking Water Research Division of EPA initiated a
cooperative agreement with the North Penn Water Au-
thority. The cooperative agreement has resulted in a
series of field monitoring and systems modeling stud-
ies that lend insight into the movement of contami-
nants in distribution systems. Previous research has
resulted in development of a steady state model the
propogation of contaminants in distribution systems. In
the paper a more intensive approach is taken to exam-
ining the actual pathways of water flow and the time of
passage and percentage of water from a given source
to a given node in a distribution system. A major finding
of the research study is the importance of adequate
hydraulic modeling of the systems being studied and
the importance of field studies in verifying systems per-
formance. The approach suggested in the research
will provide useful insight into the water quality varia-
tion that may impact consumers at the tap and the de-
velopment of monitoring strategies.

The pathogenic microorganism destruction obtained
during two-phase anaerobic digestion was compared
to that for a conventional single-stage digester using
municipal wastewater treatment sludge. Operation
was draw-and-fill. Total digester residence times of 10
days and 20 days were evaluated. Evaluations were
carried out at 35 and 53 C. Microorganisms measured
included fecal coliforms, Escherichia coli, fecal strep-
tococci, and enterovirus. Pathogen reductions were
compared to those calculated from a kinetic relation-
ship developed specifically for draw-and-fill operation.
Ascaris were added to digested sludge and held at 53
C for up to 8 hours to observe their decline with time
under thermophilic conditions. Common digester oper-
ating parameters were also measured. At the thermo-
philic temperature of 53 C essentially all the microor-
ganisms measured were reduced to undetectable
levels. At 35 C, two-phase digestion achieved from
0.48 to 0.91 greater log reduction of bacterial indica-
tors, but essentially the same reduction in virus.

There is compelling evidence that a general erosion of
the global ozone layer is occurring. Since ozone in the
stratosphere absorbs much of the shortwave solar ul-
traviolet radiation (UV-B), diminished ozone means
that more UV-B of a very specific wavelength composi-
tion will be received at the earth's surface. Evaluating
the implications for vegetation involves consideration
of the wavelength specificity of biological photochemi-
cal reactions and their sensitivity to the extent and
future solar spectrum. Recent research suggests the
occurrence of direct damaging reactions and of indi-
rect morphological and chemical responses with impli-
cations at the community and ecosystem levels.

scale incinerators are not fully understood. Pilot-scale
spray combustion experiments involving some liquid
chlorinated hydrocarbons (CHCs) and the dilute mix-
tures with hydrocarbons (HC) were undertaken at the
USEPA's Center Hill Laboratory. Individual droplet-
burning characteristics of CHCs and HCs were also

portant phenomena. The practical implications of the
experimental observations on incinerability ranking,
formation of ROSEs, and strategies for reducing
ROSEs are discussed.

Seasonal wastewater discharge programs employ dif-
ferent effluent standards during different times of the
year to take maximum advantage of a receiving
water's natural capacity to assimilate pollutants. The
rational design of the programs should try to achieve
the maximum economic benefits possible without in-
creasing the risk of water quality impairment. A method
is developed for designing seasonal programs for indi-
vidual dischargers that limits the risk of one or more
water quality standard violations in any year. The key
elements involve: (1) treating seasonal receiving water
assimilative capacity as a random variable; (2) assum-
ing Markov-like behavior of these random variables
between seasons; and (3) using a nonlinear program-
ming model to find seasonal discharge limits that mini-
mize waste treatment efforts while maintaining an ac-
ceptable annual risk of water quality violation. A case
study of controlling ammonia toxicity is presented as
well as a comparison of the potential savings available
from seasonalization for several pollutants on two
rivers with differing seasonal regimes.

The concern over solid waste disposal and dump-site
clean-up has resulted in the passage of three major
U.S. environmental laws. They are the Resource Con-
servation and Recovery Act (RCRA) of 1976, Public
Law 94-580, the Toxic Substances Control Act (TSCA)
of 1976, Public Law 94-469, and the Comprehensive
Environmental Response, Compensation and Liability
Act (CERCLA) of 1980, Public Law 96-510. The imple-
mentation of these three laws has considerably inten-
sified incineration research, because incineration rep-
resents the highest degree of destruction and environ-
mental control possible for various waste types (types
such as hazardous, medical and municipal waste). The
objective of the paper is to review the fundamentals of
incineration (combustion) and to provide an incinerator
design example to show how combustion fundamen-
tals are applied to an incineration system.

A demonstration of the American Combustion Pyretron
(TM) oxygen-enhanced burner was conducted under
the Superfund Innovative Technology Evaluation
(SITE) program. The Demonstration was conducted at
the U.S. EPA's Combustion Research Facility (CRF) in
Jefferson, Arkansas. An eight week test series was
conducted which involved burning a mixture of listed
waste K087 with contaminated soil from the Stringfel-
low Acid Pits under both oxygen enhancement and air-
only conditions. Performance under both modes of op-
eration was compared. Results show that the Pyretron
operating with oxygen enhancement could meet
RCRA emissions limitations at a throughput rate
double that for air-only operation. Scrubber liquor and
kiln ash from the tests contained no detectable levels
of contaminants from either waste stream. (Copyright

Amendments to the Safe Drinking Water Act (PL-93-
523) highlight the continuing problem of waterborne
disease by mandating the EPA to promulgate: (1) Cri-
teria by which filtration will be required for surface
water supplies; and (2) disinfection requirements for all
water supplies in the United States. There is interest
on the part of the EPA in applying the Ct concept for
determining the inactivation of Giardia lamblia cysts as

tion aile. If a utility, in addition to meeting other require-
ments, can demonstrate that through effective disin-
fection, manifested by a sufficient Ct value, it can
reduce Giardia levels by 99.9%, then it will be exempt-
ed from surface water filtration. In the paper, a model
for calculation of Ct values based on animal infectivity
data is developed. The model, based on first-order ki-
netics, relates Ct values to chlorine concentration, pH
and temperature. The model predictions are compared
to laboratory data.

The problem of contamination to land and groundwat-
er from improper handling of hazardous materials/
waste is faced by all countries. Also the need for reli-
able, cost-effective technologies to address the prob-
lem at contaminated sites exists throughout the world.
Many countries have only started to develop new inno-
vative/alternative technologies while others have al-
ready started to apply these technologies to the clean-
up of contaminated sites. The purpose of the NATO/
CCMS Pilot Study is to discuss and evaluate new inno-
vative/alternative technologies and/or existing sys-
tems that may be applicable to the cleanup of contami-
nated sites. Through the pilot study the exchange of in-
formation on new and existing technologies for dealing
with problem hazardous waste sites is promoted. The
pilot study is made up of an international group of ex-
perts drawn from the participating countries. The
study, which was initiated in 1986, is planned to last
five years. It is piloted by the United States and copilot-
ed by the Federal Republic of Germany (FRG) and the
Netherlands. The report includes an overview and his-
tory of the NATO/CCMS Pilot Study, but it primarily
presents a documentation of the NATO/CCMS

Wheat, rice and soybean were grown to determine if
CO2-induced increases in photosynthesis, biomass,
and yield are modified by increases in ultraviolet-B
(UV-B) radiation corresponding to stratospheric ozone
depletion. The experimental conditions simulated
were: (1) an increase in CO2 concentration from 350 to
650 microliters per liter, (2) an increase in UV-B radi-
ation corresponding to a 10% ozone depletion at the
equator; and (3) a and b combination. Seed yield and
total biomass increased significantly with elevated
CO2 in all three species when compared to the con-
trol. However, with concurrent increases in UV-B and
CO2, no increase in either seed yield (wheat and rice)
or total biomass (rice) was observed with respect to
the control. In contrast, CO2-induced increases in
seed yield and total plant biomass were maintained or
increased in soybean within the elevated CO2, UV-B
environment. Whole leaf gas exchange indicated a sig-
nificant increase in photosynthesis, apparent quantum
efficiency (AQE) and water-use-efficiency (WUE) with
elevated CO2 in all 3 species. Including elevated UV-B
radiation with high CO2 eliminated the effect of high
CO2 on photosynthesis and WUE in rice and the in-
crease in AQE associated with high CO2 in all species.
Elevated CO2 did not change the apparent carboxyla-
tion efficiency (ACE) in the three species although the
combination of elevated CO2 and UV-B reduced ACE
in wheat and rice. The results of the experiment illus-
trate that increased UV-B radiation may modify CO2-
induced increases in biomass, seed yield and photo-
synthetic parameters and suggest that available data
may not adequately characterize the potential effect of
future, simultaneous changes in CO2 concentration
and UV-B radiation.

Two soybean, (Glycine max (L.) Merr.) cultivars, Essex
and Williams, were grown in the field for 6 consecutive
seasons under ambient and supplemental levels of ul-
traviolet-B radiation to determine the potential for al-
terations in yield or seed quality with a reduction in the
stratospheric ozone column. The supplemental UV-B
fluences simulated a 16 or 25% ozone depletion. The
data presented here represent the first field experi-
ment conducted over multiple seasons which assess-
es the effects of increased UV-B radiation on seed
yield. Overall, the cultivar Essex was found to be sensi-
tive to UV-B radiation (yield reductions of 20%) while
the cultivar Williams was tolerant. However, the effec-
tiveness of UV-B radiation in altering yield was strongly
influenced by the seasonal microclimate, and the 2
cultivars responded differently to these changing fac-
tors. Yield was reduced most in Essex during seasons
in which water availability was high and was reduced in
Williams only when water was severely limiting. The re-
sults of the experiments demonstrate the necessity for
multiple-year experiments and the need to increase
understanding of the interaction between UV-B radi-
ation and other environmental stresses in order to
assess the potential consequences of stratospheric
ozone depletion.

ent and supplemental levels of ultraviolet-B (UV-B) ra-
diation (supplemental daily dose of 5.1 effective kilo-

duced to -2.0 megapascals by the exclusion of natural
precipitation in the drought plots and were maintained
at approximately -0.5 megapascal by supplemental irri-
gation in well-watered plots. Plant growth and gas ex-
change characteristics were affected under both
drought and supplemental UV-B radiation. The com-
bined effect of both drought and UV-B radiation on
photosynthetic gas exchange was a reduction in ap-
parent quantum efficiency and the rapid appearance of
biochemical limitations to photosynthesis concomitant
with reduced diffusional limitations. However, the com-
bination of stresses did not result in additive effects on
total plant growth or seed yield compared to reduc-
tions under either stress independently.

Biologically enhanced oxygen transfer has been a hy-
pothesis to explain observed oxygen transfer rates in
activated sludge systems that were well above that
predicted from aerator clean-water testing. The en-
hanced oxygen transfer rates were based on tests
using BOD bottle oxygen uptake rates (OURs) on sam-
ples removed from the activated sludge system.
Bench- and full-scale plant studies were performed to
compare results of in situ OUR measurement tech-
niques to BOD bottle OUR measurements. The studies
showed that the condition of low dissolved oxygen
(DO) and high OUR for which the greatest enhanced
oxygen transfer was reported resulted in OURs in the
BOD bottle tests well above the actual in situ OURs.
For high DO and high OUR activated sludge operating
conditions, the BOD bottle OURs were below the
actual in situ OURs. The BOD bottle OUR values accu-
rately described in situ OURs for endogenous respira-
tion conditions with nonlimiting DO concentrations.
The results suggest that previously observed biologi-
cally enhanced oxygen transfer was not actually oc-
curring but was the result of the BOD bottle test
method and activated sludge operating condition.

The paper discusses combining experimental results
from a pilot-scale rotary kiln incinerator simulator with
a theoretical model in order to explore the potential of
minimizing transient emissions through changes in kiln
rotation speed and temperature, steady state oxygen
enrichment, and oxygen enrichment in a dynamic
mode. Results indicate that transient organic emis-
sions can indeed be minimized by changes in these
kiln operating parameters but, because of the complex
interactions of physical and chemical processes con-
trolling emissions, the appropriate abatement proce-
dures must be implemented carefully. Transient emis-
sions of organics occur from rotary kiln incinerators
when drums containing liquid wastes bound on sor-
bents are introduced in batches. Physical processes
controlling the release of waste from the sorbent mate-
rial are greatly affected by the rotation speed and tem-
perature of the kiln. Local partial pressure of oxygen in-
fluences the rate of oxidation of the puff formed inside
the kiln. These physical and chemical phenomena can
be used to control transient emissions by oxygen en-
richment, where it is done in either a steady or a dy-
namic mode.

Wind-tunnel experiments and a theoretical model con-
cerning the flow structure and pollutant diffusion over
two-dimensional valleys of varying aspect ratio are de-
scribed and compared. Three model valleys were
used, having small, medium, and steep slopes. Meas-
urements of mean and turbulent velocity fields were
made upstream, within, and downwind of each of
these valleys. Concentration distributions were meas-
ured downwind of tracer sources placed at an array of
locations within each of the valleys. The data are dis-
played as maps of terrain amplification factors, defined
as the ratios of maximum ground-level concentrations
in the presence of the valleys to the maxima observed
from sources of the same height located in flat terrain.
Maps are also provided showing the distance to loca-
tions of the maximum ground-level concentrations.
The concentration patterns are interpreted in terms of
the detailed flow structure measured in the valleys.
These data were also compared with results of a math-
ematical model for treating flow and dispersion over
two-dimensional complex terrain. The model used the
wind-tunnel measurements to generate mean flow
fields and eddy diffusivities, and these were applied in
the numerical solution of the diffusion equation. Meas-
ured concentration fields were predicted reasonably
well by the model for the valley of small slope and
somewhat less well for the valley of medium slope. Be-
cause flow separation was observed within the steep-
est valley, the model was not applied in this case.

The study examined relations between mercury con-
centrations in walleyes Stizostedion vitreum and the
characteristics of clear-water Wisconsin lakes, which
spanned a broad range of pH values (5.0-8.1) and
acid-neutralizing capacities (-9 to 1,017 micrpgram eq/
L). Total concentrations of mercury in axial muscle
tissue of walleyes (total length, 25-56 cm) varied from
0.12 to 1.74 microgram g/g wet weight. Concentra-
tions were greatest in fish from the eight lakes with pH
less than 7.0; concentrations in these fish equaled or
exceeded 0.5 microgram g/g in 88% of the samples
analyzed and 1.0 microgram g/g in 44%. In the five
lakes with pH of 7.0 and above, concentrations ex-
ceeded 0.5 microgram g/g in only 1 of 21 walleyes.
Multiple regression revealed that lake pH and total
length of fish accounted for 69% of the variation in
mercury concentration in walleyes. Regression models
with total length and either waterborne calcium or acid-
neutralizing capacity as independent variables ac-
counted for 67% of the variation in concentration. The
observed differences in fish mercury concentration be-
tween the low-pH and high-pH lakes could not be logi-
cally attributed to differences in growth rate or diet
among the walleye populations. Moreover, it is improb-
able that mercury influxes to the low-pH lakes were
greater than those to the high-pH lakes, because of
the close proximity and spatial interspersion of low-
and high-pH lakes.

The selection of Principal Organic Hazardous Con-
stituents (POHCs) and determination of the incinerabi-
lity ranking have been the subject of considerable sci-
entific and policy debate since the RCRA/hazardous
waste incinerator standards were established in 1981.
POHCs have typically been selected for measurement
of their Destruction and Removal Efficiencies (DREs)
during incinerator trial burns based on their heats of
combustion. In 1987, EPA's OSW joined ORD to
evaluate the possibility of developing an improved
POHC incinerability ranking system based on the con-
cept of thermal stability under oxygen-starved, post-
flame conditions. A theoretical evaluation of the ther-
mal stability of 320 organic compounds on the Appen-
dix VIII list was undertaken. These compounds were
grouped in accordance with their possible reaction
mechanisms. Selected compounds were tested in a
laboratory-scale thermal decomposition unit equipped
with a gas chromatograph to determine their Destruc-
tion Efficiencies (DEs) under low-oxygen, post-flame
conditions. The Paper provides both the 'heat of com-
bustion' ranking system and the 'thermal stability'
ranking system for comparison and application.

Total organic halide (TOX) analyzers are commonly
used to measure the amount of dissolved halogenated
organic byproducts in disinfected waters. Because of
the lack of information on the identify of disinfection
byproducts, rigorous testing of the dissolved organic
halide (DOX) procedure for method bias is not always
possible. The note presents the results of a brief study
comparing two commercial TOX analyzers with neu-
tron activation. The purpose was to determine if differ-
ential bias exists between the two analyzers, and to
determine analyte recovery of adsorbed disinfection
byproducts. Disinfection byproducts of aquatic fulvic
acid were prepared using the following disinfectants:
chlorine, bromine, and monochloramine. Analysis of
the samples indicated that the two commercial TOX
analyzers gave similar results. Neutron activation anal-
ysis suggested that organic chlorine recovery from the
activated carbon adsorbent was complete, however,
results with organic bromine recovery were inconclu-
sive. Additional tests indicated that one of the TOX
analyzers is subject to significant interferences from in-
organic iodide. (Copyright (c) 1990 Gordon and

have shown that sludge management system limita-
tions were severe enough to contribute to non-compli-
ance with NPDES permits in 49 percent of the plants
evaluated. Most limitations could be attributed to one
or more of the following: inaccurately estimated
masses and/or volumes of waste sludge, inadequately

mass and/or volume variations, and inflexibility in
sludge processing operations and sludge manage-

The use of electrical energy in the form of plasma has
been considered as a potentially efficient means of de-
contaminating hazardous waste. Only a few attempts
have been made to actually treat hazardous waste
with plasma, however. The paper discusses both
direct and indirect waste heating with plasma. Direct
heating involves the direct injection of liquid waste into
the plasma plume. Indirect heating involves using the
plasma to create a bath of molten solid material which
is used to heat and decontaminate solid hazardous

All sectors are beginning to see the inherent advan-
tages that arise from avoiding the generation of pollut-
ants in the first place - the reductions in environmental
and health hazards, the avoidance of Federal, State
and local regulatory requirements, the more efficient
use of raw materials, the more economical production
of goods and services, the conservation of natural re-
sources, and the elimination of potential liability. The
report is a brief outline of the mission, structure and ac-

Until recently most interest in drinking water quality
has been in the finished water as it leaves the treat-
ment plant The Safe Drinking Water requires that
MCLs be met at the consumers tap. Because finished
water may undergo substantial changes while being
transported through the distribution system to the con-
sumer, interest has increased on the effect the system
itself may have on water quality. The paper reports on
a study that was conducted in cooperation with the
North Penn Water Authority in Lansdale, Pennsylvania
to study the effects that hydraulic behavior may have
on contaminant propagation in the system. The study
demonstrates that water quality varies not only with
time but with space as well. Methods for continuous
monitoring were evaluated as part of the study. Sever-
al different types of models were also developed in
order to provide a framework for studying contaminant
propagation.

In studies of the northeastern red spruce ecosystem,
several points evoke some agreement: (1) many high-
elevation sites exhibit substantial post-1960 mortality
that could be due to winter injury; (2) there is wide-
spread pre-1950 growth increase with a subsequent
post-1960 growth decrease; (3) many locations show
none of these effects; and (4) dendro-climate models
suggest that late summer and early winter tempera-
tures of the previous year are significant determinants
of red spruce year-to-year growth. It is a mistake to ad-
vocate a single cause at this time, because there is
compelling evidence that both climate and stand dy-
namics are involved to some degree. The study of
long-term forest trends based on tree-ring data is diffi-
cult and subject to interpretation, but it is unlikely that
other data is available for most natural forest areas. In
fact, progress made in the study of northeastern red
spruce owes much to tree-ring analysis, and other eco-
logical studies could benefit as well.

An outdoor pen study was conducted with mallards
(Anas platyrhynchos) to evaluate the effects of an 9-d
dietary exposure to methyl parathion (400 ppm) on egg
laying and incubation when treatment was initiated at
different times in the nesting cycle. Treatment groups
were defined as egg laying (chemical initiated after
fourth egg laid in nest), early incubation (initiated after
day 4 of incubation), late incubation (initiated after day
16 of incubation) and control (no chemical). Forty-eight
pairs (12/group) were allowed to nest and hatch
broods. In the egg laying group, daily egg production
was reduced significantly during the treatment period
compared to controls, but 4 of 10 hens resumed pro-
duction post-treatment. One of ten control hens aban-
doned its nest, whereas 17 of 23 hens in the early and
late incubation groups either died or exhibited changes
in incubation behavior, with 7 hens abandoning their
nests and 6 displaying reduced nest attentiveness for
one or more days during treatment. Reproductive pa-
rameters were not significantly different between treat-
ment groups, but the number of hatchlings per nest
was 61, 43 and 58% of controls for the egg laying,
early incubation and late incubation groups, respec-
tively. The study showed that nesting success may be
impacted by short dietary exposures to methyl parath-
ion, particularly during early incubation.

The paper gives results of an evaluation of a 0.6 MW
precombustion chamber burner, designed for in-fur-
nace NOx control, high combustion efficiency, and ret-
rofit applications, for use with high nitrogen content
fuel/waste mixtures. The 250- to 750-ms residence
time precombustion chamber burner mounted on a
prototype watertube package boiler simulator used air
staging and in-furnace natural gas reburning to control
NOx emissions. The paper reports results of research
in which the low NOx precombustor was used to exam-
ine the co-firing characteristics of a nitrogenated pesti-
cide, containing dinoseb (2-sec-butyl-4,6 dinitro-
phenol) in a fuel-oil/xylene solvent. The dinoseb for-
mulation as fired contained 6.4% nitrogen. NO emis-
sions without in-furnace NOx control exceeded 4400
ppm (at 0% 02). When NOx controls in the form of air
staging and natural gas reburning were used, these
emissions were reduced to < 150 ppm (96% reduc-
tion). Average CO and total hydrocarbon emissions
were typically < 15 and 2 ppm, respectively. No dino-
seb was detected in any emission sample, and the de-
struction efficiency was determined to be > 99.99%.
Mutagenicity studies of the dinoseb emissions showed
that reburning (used for NOx control) reduced the mu-
tagenic emission factor about 60-70% from that with
air staging alone.

Rsh physiologists have provided the basic information
on gill morphology, gill function, and vascular dynam-
ics with which to understand branchial flux of gases,
water, and ions. In addition, pharmacologists and toxi-
cologists, working in the area of drug action, have
characterized the physicochemical attributes of xeno-
biotic chemicals that determine their rate of movement
across biological membranes. Recently, aquatic toxi-
cologists have applied the information to the question
of what mechanisms control the movement of organic
chemicals across fish gills and how exchange is affect-
ed by chemical properties. Mathematical models were
developed that predict gill exchange as a function of
basic processes such as water flow across the gills,
blood flow through the gills, partitioning of the chemi-
cal between water and blood, and diffusion between
blood and water across gill epithelia. Such mechanistic
models can predict the effects of environmental condi-
tions on exchange rates of xenobiotics. To fully devel-
op a predictive capability for xenobiotic uptake and dis-
tribution by fish, it will be necessary to incorporate
these gill models into emerging, physiologically based
models for the entire animal.

The interaction of indoor air pollutants with interior sur-
faces (i.e., sinks) is a well known, but poorly under-
stood, phenomenon. Studies have shown that re-emis-
sions of adsorbed organic vapors can contribute to
elevated concentrations of organics in indoor environ-
ments. Research is being conducted in small environ-
mental test chambers to develop data for predicting
sink behavior. The paper reports on the development
of sink models based on fundamental mass transfer
theory. The results of experiments conducted to deter-
mine the magnitude and rate of adsorption and de-
sorption of vapor phase organic compounds for sever-
al materials are presented. Five materials were evalu-
ated: carpet, painted wallboard, ceiling tile, window
glass, and upholstery. Two organic compounds were
tested with each material: tetrachloroethylene (a
common cleaning solvent) and ethylbenzene (a
common constituent of petroleum-based solvents
widely used in consumer products). The results of the
experimental work are presented showing the relevant
sink effect parameters for each material tested and
comparing the sorptive behavior of the two organic
compounds evaluated. An indoor air quality (IAQ)
model was modified to incorporate adsorption and de-
sorption sink rates. The model was used to predict the
temporal history of the concentration of total vapor
phase organics in a test house after application of a
wood finishing product. The predicted results are pre-
sented and compared to measured values. Sugges-
tions for further research on indoor sinks are present-
ed. (Copyright (c) 1991 Danish Technical Press.)

The objective of the paper is to construct a class of
models for analyzing data in initiation-promotion (IP)
studies. After the application of an initiator in animal IP
studies, histochemical and/or histopathologic criteria
are used to define the foci that are postulated to be the
origin of tumors. Thus, the dynamics of foci growth are
of inherent interest in the study of the mechanism of
carcinpgenesis. In the paper, models to explain these
dynamics are developed and can be used to differenti-
ate among proposed mechanisms of tumor formation
and promotion. Examples are given to illustrate useful
concepts for analyzing data from IP studies.

The average concentrations of a large number of fine
particle aerosol and VOC species measured in ten
Boise, Idaho, residences in wintertime have been ap-
portioned according to their contributions from all
inside sources and all outside sources, regarded as
two composite source categories. Air change rates for
the residences were in the range 0.2 - 0.8/hr. None of
the residences had obvious major indoor sources
(smokers, wqodburning appliances, etc.). The two cat-
egory apportionment was accomplished through use
of the single chamber mass balance indoor air quality
model given by Dockery and Spengler. The method
depends on the availability of average concentrations
measured outside each residence during the same
sampling periods used for the inside measurements,
and on the ability to identify one or more species that
have negligible indoor sources. Calculated infiltration
factors (the indoor/outdoor ratio in the absence of
indoor sources) for fine particle species averaged 0.5,
and varied in a reasonable way with measured air
change rates, essentially independent of species. Infil-
tration factors for the VOCs were indistinguishable
from unity. The relative importance of indoor and out-
door sources to measured indoor concentrations
showed great variation between species and between
residences. In most homes the indoor source contribu-
tion was dominant for fine particle Si, Ca, and Fe, while
the infiltration contribution was dominant for S, K, Pb,
Zn, mass, and extractable organic matter. Indoor con-
tributions to individual VOCs were frequently very large
at a few residences and negligible at the others. (Copy-

ined. Special graphic displays of the results are pre-
sented to have great potential as an easily quantifiable

The paper summarizes a study of the relationship be-
tween Gaussian plume models and wind-tunnel
models. Wind-tunnel measurements of the distribution
of tracer concentrations downwind of a point source in
the near wake of a rectangular model building were
evaluated. Profiles of mean velocity and turbulence
were measured to characterize the flow. These experi-
ments were conducted in both a low-turbulence
boundary layer and a simulated-atmospheric boundary
layer. The study covered a range of four flow speeds
arid four different sized buildings. The differences in
observed velocity and concentrations between the re-
sults for the tow turbulence and simulated atmospheric
boundary layer flow were not significant very near the
building, but these differences increased in signifi-
cance at downstream distance greater than 10 times
the building height The transition from buHding-affect-
ed dispersion levels to levels that were not significantly
different from dispersion without a building was a func-
tion of the size of the building. The application of a
modified Gaussian plume model showed it to be a
simple, wen-suited complement to wind-tunnel meas-
urements of mean concentrations.

Several series of experiments were performed in a
stratified towing tank to study the near-field flow of a
linearly stratified fluid over an isolated three-dimen-
sional hill. The streamlines were obtained in the labo-
ratory using a stereographic method to determine the
paths of plumes of dye released upstream of the hill.
Velocities over the hill center were obtained by analy-
sis of video recordings of the dye plumes and with a
propeller anemometer. The results of these experi-
ments are compared with numerical solutions, comput-
ed using Fast Fourier Transforms, of the linearized
aquations of motion for an inviscid fluid. Good agree-
ment is found for Froude numbers (based on the hill
height) greater than about 2.0. For Froude numbers
greater than about 4.0, flow patterns were observed to
differ only slightly from those for neutral flow.

Seminomas and dysgerminomas are epizootic in soft-
shell clams, Mya arenaria, from three Maine estuaries
contaminated with herbicides. The first epizootic was
discovered in 22% of clams collected as Searsport
near Long Cove Brook and three culverts that con-
veyed heating oil and jet fuel spilled from a tank farm in
1971. Data from subsequent epizootiological studies
and a series of long-term experimental exposures of
softshell clams to no. 2 fuel oil, JP-4, andJP-5 jet fuel
at the U.S. EPA, Environmental Research Laboratory
in Narragansett, Rhode Island, and in the field did not
support an etiology by these petroleum products. In
the two recent epizootics reported here, the germino-
mas have been observed in 3% of the softshell clams
collected from Roque Bluffs near Machiasport and
from 35% of softshell clams collecled from Dennys-
ville. Mya collected at Dennysville had pericardial me-
sotheliomas and teratoid siphon anomalies in addition
to gonadal neoplasms. Estuaries at Dennysville had
been contaminated by herbicides in a 1979 accidental
spray overdrift during aerial application of Tordon 101
to adjacent forests. Further investigation determined
widespread use of the herbicides Tordon 101,2,4-D,
2,4,5-T, and other agrochemicals in an extensive for-
estry and blueberry industry in both the Roque Bluffs
and the Dennysville areas. Herbicide applications at
Searsport were confirmed for railroad property border-
ing Long Cove estuary and for Long Cove Brook adja-
cent to the estuary where a highway department re-
portedly cleans its spray equipment Herbicide con-
tamination is the only common denominator identified
at all three sites where Mya have been found with go-
nadal neoplasms.

The eastern oyster (Crassostrea virginica) developed
neoplastic disorders when experimentally exposed
both in the laboratory and field to chemically contami-
nated sediment from Black Rock Harbor (BRH),
Bridgeport, Connecticut. Neoplasia was observed in
oysters after 30 and 60 days of continuous exposure in
a laboratory flow-through system to a 20 mg/L sus-
pension of BRH sediment plus postexposure periods
of 0, 30, or 60 days. Composite tumor incidence was
13.6% (49 neoplasms in 40, n = 295) for both expo-
sure. Tumor occurrence was highest in the renal ex-
cretory epithelium, followed in order by gill, gonad,
gastrointestinal, heart, and embryonic neural tissue.
Regression of experimental neoplasia was not ob-
served when the stimulus was discontinued. In field ex-
periments, gill neoplasms developed in oysters de-
ployed in cages for 30 days at BRH and 36 days at a
BRH dredge material disposal area in Central Long
Island Sound, and kidney and gastrointestinal neo-
plasms developed in caged oysters deployed 40 days
in Quincy Bay, Boston Harbor. Oysters exposed to
BRH sediment in the laboratory and in the field accu-
mulated high concentrations of polychlorinated bi-
phenyls (PCBs), polyaromatic hydrocarbons (PAHs),
and chlorinated pesticides. Chemical analyses demon-
strated high concentrations of PCBs, PAHs, chlorinat-
ed pesticides, and heavy metals in BRH sediment.
Known genotoxic carcinogens, cocarcinogens, and
tumor promoters were present as contaminants. The
uptake of parent PAH and PCBs from BRH sediment
observed in oysters also occurs in blue mussels (Myti-
lus edulis). Winter flounder fed BRH-contaminated
blue mussels contained xenobiotic chemicals ana-
lyzed in mussels.

Innovative practices for treating waste streams con-
taining heavy metals often involve technologies or sys-
tems that either reduce the amount of waste generat-
ed or recover reusable resources. With the land dis-
posal of metal treatment residuals becoming less of an
accepted waste management alternative, waste mini-
mization practices have received increasing popularity
in the primary metals industry. Preferred management
practices for reducing or eliminating generated wastes
are source reduction (i.e., material sustitution, recycle/
reuse) and reduction of toxicity in order to meet tech-
nology-based treatment standards. Major topics to be
discussed in the chapter will focus on waste stream
characterizations, process descriptions, and summa-
rized results on demonstrations and audits. Only state-
of-the-art and innovative approaches will be consid-
ered for review. Particular emphasis will be placed on
waste minimization approaches (e.g. source reduction
techniques, concentration and reuse of waste con-
taminants, material substitution), recovery techniques
(e.g. electrolytic recovery, membrane technologies,

Metallic, masonry, and other solid debris that may be
contaminated with hazardous chemicals litter numer-
ous hazardous waste sites in the United States. Poly-
chlorinated biphenyls (PCB's), pesticides, lead or other
metals are some of the contaminants of concern. In
some cases cleanup standards have been established
(e.g., 10 micrograms PCB's/100 sq cm for surfaces to
which humans may be frequently exposed). Decon-
taminated debris could be either returned to the site as
'clean' fill, or, in the case of the metallic debris, sold to
a metal smelter. The project involves the development
and demonstration of a technology specifically for per-
forming on-site decontamination of debris. Both
bench-scale and pilot-scale versions of a debris wash-
ing system (DWS) have been designed, constructed
and demonstrated. The DWS entails the application of
an aqueous solution during a high-pressure spray
cycle, followed by turbulent wash and rinse cycles. The
aqueous cleaning solution is recovered and recondi-
tioned for reuse concurrently with the debris-cleaning
process, which minimizes the quantity of process
water required to clean the debris. (Copyright (c) 1991,

A review of recently published literature was per-
formed to ascertain the levels of indigenous human
enteric viruses found in untreated surface and subsur-
face freshwaters, and in drinking water which has been
subjected to the complete process of conventional
treatment. For the purpose of the review, the criterion
used for defining conventional drinking water treat-
ment was that of an operation which included coagula-
tion followed by sedimentation, filtration, and disinfec-
tion. Also assessed was the stepwise efficiency of
conventional drinking water treatment, as practiced at
full-scale facilities, for removing indigenous viruses
from environmental freshwaters. In addition, a list was
compiled of recently published statistical correlations
relating to the finding of indigenous viruses in water.

The time-averaged concentration of hydrocarbon and
oxygen vapors were measured in the unsaturated
zone above the residually contaminated capillary
fringe at the U.S. Coast Guard Air Station in Traverse
City, Michigan. Total hydrocarbon and oxygen vapor
concentrations were observed over a 13-month
period. Supplementary grain size, porosity, and mois-
ture content data support the assumption of a uniform,
homogenous site geology which, in view of the planar
hydrocarbon source term, abundant oxygen, and
sparse data base, is suitable for simple analytical mod-
eling. In the assumed absence of advection, leaching,
and transcience, the analysis is a straight-forward bal-
ance of gaseous diffusion and biological degradation
coupled stoichiometrically in the two reacting constitu-
ents. Volatilization is shown to be a significant trans-
port mechanism for hydrocarbons at Traverse City,
and biodegradation prevents the escape of apprecia-
ble contamination to the atmosphere for most loca-
tions at the site. Little oxygen is expected to reach the
water table because of the aerobic biodegradation
process in the unsaturated zone. (Copyright (c) 1991

The sorption and degradation of several benzidine-
based dyes were studied in sediment-water systems.
Studies in resaturated sediment demonstrated that
sorption was strongly dependent on pH and the nature
and concentration of the inorganic salt in solution.
Degradation of the dyes in anaerobic pond sediment
followed pseudo-first-order kinetics with half-lives
ranging from 2 to 16 d. Product studies indicated that
the amount of recovered benzidine accounted for only
2 to 5% of lost Direct Red 28. Studies in pH-amended
pond sediment demonstrated that degradation is inhib-
ited when the dyes are strongly sorbed to the sedi-
ment.

Chemical exchange dynamics expected for diffusive
transfer of a chemical between aqueous solution and
plant shoots, and expected bioconcentration based on
partitioning properties of the chemical, are explored by
using a three-compartment model. The model utilizes
three dynamic compartments-leaves, stems, and
aqueous exposure medium. Chemical mass flux is de-
pendent on the morphometry of the plant species, on
exposure concentration, and on partitioning character
of the chemical. The steady-state bioconcentration
factor, K(sub SH), is dependent on composition of the
plant species and partitioning character of the chemi-
cal. The model was parameterized for three species of
aquatic plants (Myriophyllum spicatum, Bacopa caro-
liniana, and Hydrilla verticillata) and two chlorinated
benzenes (1,2.3,4-tetrachlorobenzene (TCB) and 1,2-
dichlorobenzene (DCB)). Predictions of uptake and
bioconcentration are compared to results of static lab-
oratory studies conducted with whole shoots of the
three species over exposure periods ranging from 1 h
to 21 d. Shoots approach steady-state tissue burdens
between 1 and 3 d after initial exposure. K(sub SH)
values for TCB (360-750), the more hydrophobic
chemical, are at least one order of magnitude greater
than those measured for DCB (11 -28).

The objective of the research was to measure the time
ot travel (TOT) of inorganic solutes through laboratory
columns of compacted clay, to determine the physical
and geochemical parameters that controlled solute
transport through the soil columns, and to compare
measured and predicted TOT'S. Two clay soils were
used: kaolinite (a low-plasticity, commercially-pro-
duced clay) and Lufkin day (a highly plastic, naturally-
occurring day soil). Anionic tracers were chloride and
bromide; potassium and zinc were the cationic tracers.
Diffusion cells were designed, constructed, and used
to measure the effective diffusion coefficient of the
tracers in the two soils. Diffusion coefficients for
anions were typically 0.000002 to 0.000007 sq cm/s;
somewhat lower values were determined for cations.
Column tests showed that the effective porosity ratio
(defined as effective divided by total porosity) in-
creased with increasing hydraulic gradient in kaolinite
from a tow of about 0.25 at a gradient of 1 toahighof 1
at a gradient of 20. With Lufkin clay, the effective po-
rosity ratio was between 0.02 and 0.16. Breakthrough
times were controlled much more by the tow effective
porosities than by molecular diffusion. The computer
program SOILINER predicted times of travel that were
larger than actual TOT's by a factor of up to 52. The
failure to account for effective porosity ratios less than
1 was the cause for the poor predictions from SOI-
LINER.

As part of an investigation of the developmental ef-
fects and structure-activity relationships of aliphatic
acids, 2-methylhexanoic acid was administered by
gavage to Sprague-Dawley rats on gestation days 6-15
at doses of 0, 300, and 400 mg/kg/day. The dams
were allowed to deliver and their litters were examined
through postnatal day 6. Pups that were found dead
were examined for soft-tissue alterations. On day 6,
two survivors per litter were preserved for skeletal ex-
amination. Maternal toxicity was demonstrated at both
300 and 400 mg/kg by weight loss and altered respira-
tion (rales, dyspnea). In spite of the maternal toxicity
present, there were no clear toxic effects on develop-
ment; litter size, pre- and postnatal viability, and pup
weights were unaffected by treatment. Skeletal exami-
nations of selected pups yielded inconclusive data; a
slight increase in the incidence of lumbar ribs was
present a 400 mg/kg, but was not clearly attributable
to treatment.

The Energy Security Act of 1980 established a pro-
gram to provide financial assistance to private industry
in the construction and operation of commercial-scale
synthetic fuels plants. The Parachute Creek Shale Oil
Program is one of the four projects awarded financial
assistance. The support agreement included develop-
ment of an Environmental Monitoring Plan, incorporat-
ing existing compliance monitoring and supplemental
monitoring on water, air, solid waste, worker health
and safety, and socioeconomic impacts during the
period 1986-1993. Phase I of the project is to produce
10,000 barrels per day of syncrude from oil shale,
using the Unishale 'B' process. The third annual meet-
ing of the Monitoring Review Committee for the project
included discussions of air, water and biological moni-
toring programs; spent shale pile inspecting; industrial
hygiene monitoring; and medical assessments. Re-
sults of sampling 18 supplemental locations found no

A Fourier transform infrared remote sensor (FTIR-RS)
was used to measure chemical emissions at the Shav-
er's Farm Superfund site in northwestern Georgia. The
system was bistatic with a source/receiver at one end
of a 250 m path and a retroreflector at the other end.
The source/receiver was a Nicolet Model 730 FTIR
system coupled to a telescope with the appropriate
transfer optics. The average concentrations of target
gases along the path are inferred by matching field
spectra with reference spectra of precisely measured
quantities of the target gases. Measurements indicat-
ed that benzonitrile and benzaldehyde concentrations
at the site were lower than the FTIR-RS detection
limits of 70 and 16 ppm-m, respectively. Background
IR radiation was successfully eliminated by modulating
the IR beam before it was transmitted along the path.
Quality assurance measurements to establish the pre-
cision and accuracy of known gas burdens (ppm-m)
were carried out using a 15-cm cell containing high
concentrations of several gases.

Procedures used to identify or screen for the presence
of neurotoxicity are usually designed to test large num-
bers of animals and are not considered to be as sensi-
tive to subtle effects as more specialized tests for
neurobiological dysfunction. For purposes of screen-
ing, the use of a functional observational battery (FOB)
is now generally accepted. A number of batteries con-
taining different observations and measurements have
been developed in several laboratories for rodents,
dogs, and non-human primates. FOB used in screen-
ing typically assess several neurobiological domains
including neuromuscular (i.e., weakness, incoordina-
tion, abnormal movements, gait, motor seizures, myo-
clonia, rigidity and tremor), sensory (i.e., auditory,
visual and somatpsensory) and autonomic (i.e., pupil
response, salivation) functions. Most FOB used for
screening do not assess cognitive function (i.e., learn-
ing and memory). FOB evaluations can yield important
information concerning dose-response characteriza-
tics and data on the onset, duration and persistence of
an effect. FOB should be able to differentiate neuro-
toxicants from non-neurotoxicants and neurotoxicants
having different mechanism(s) or srte(s) of action.

Investigations of the effects of runoff from pesticide
sprayed fields on survivorship of the larvae of the
grass shrimp Palaemonetes pugio are described.
Gravid shrimp were held in cages in the surface waters
of two estuarine creeks; one creek received runoff
from fields sprayed with the pesticides permethrin and
thiodicarb while the other creek received runoff from
an unsprayed forested area. Larvae released from
field-exposed shrimp were reared in the laboratory in
runoff water from the farm, from forest drainage, and in
control water. Permethrin was undetectable (< 1 ng/
sample) in all water except in one replicate of farm
runoff. Survivorship was high (75-94%) in all treat-
ments except for larvae reared in farm runoff water
(27-35%). In a second experiment three weeks after
pesticide application, survivorship was high (94-98%)
in all treatments. The study concludes that runoff from
agricultural fields sprayed with pesticides applied in ac-
cordance with labeled instructions can significantly
reduce survivorship of larval grass shrimp, although
cause of mortality is unknown.

Four mixtures of C1 and C2 chlorinated hydrocarbons,
diluted in heptane, were burned in a Turbulent Flame
Reactor (TFR) under high and low oxygen conditions.
Emissions of undestroyed feed, stable organic by-
products, carbon monoxide, carbon dioxide and
oxygen were measured and compared with the results
of other thermal decomposition and combustion re-
search on similar compounds. The results show that
the volatile compounds emitted in the TFR's exhaust
could be predicted based on an understanding of both
the combustion chemistry of the compounds in ques-
tion and of the physical environment existing within the
combustion device during operation. Soot formation
complicates the characterization of volatile organic
emissions. (Copyright (c) Pergamon Press 1989.)

Although the specific chemicals or factors actually re-
sponsible for induction of arrhenoidy among mosquito-
fish have not yet been identified, it is known that a wide
variety of potential compounds occur as by-products
from the processing of wood pump. The purpose of the
study was to investigate the morphological and behav-
ioral responses of mosquitofish environmentally ex-
posed to kraft mill effluent (KME) and to evaluate the
potential of these responses as bioassay endpoints. A
method to quantify the morphological or behavioral re-
sponses of mosquitofish should provide an in situ
bJoindicator to assess impact of KME discharge on re-

A computer program has been developed to simulate
vapor and heat transfer processes in multiphase flow
in a tube. The primary purpose is to apply it to the res-
piratory conditions at which aerosol-laden air is inhaled
in the human respiratory tract The method of evaluat-
ing the analytical solution and the input needed to run
the program are described. Aerosol-induced coupling
between temperature and vapor concentration fields
under different respiratory conditions is investigated.
Simulation results for air-water vapor mixtures agree
well with both simplified analytical solutions and with
the results of Barrett and dement for an infinite plane.
The effect of tube radius on temperature, relative hu-
midity and particle size is also demonstrated. (Copy-

An objective of the text is to demonstrate advantages
of interdisciplinary efforts, specifically, applications of
engineering technology to hearth effects issues. The
work describes the development of surrogate systems
of the human lung for use in studies of hygroscopic
growth kinetics and related deposition of inhaled parti-
cles. The models have become increasingly more
physiologically realistic. Notable accomplishments are
the successful simulations of in vivo environmental
conditions, namely: (1) temperature and relative hu-
midity atmospheres; (2) airstream profiles and thermo-
dynamic processes; and, (3) lung morphology. Meas-
urements of hygroscopic characteristics of a laborato-
ry aerosol (NaCI) and bronchodilator drugs used in aer-
osol therapy were made using one of the models and
are reported herein. The data clearly demonstrate the
respective effects of respiratory tract geometry and
particle chemical composition upon the behavior of in-
haled substances. The surrogate lungs, offering
unique research opportunities detailed within, are in-
tended for experimental investigations that are com-
plementary to inhalation exposures with human sub-
jects. (Copyright (c) 1990 by Hemisphere Publishing

The constituent particles of many ambient and work-
place aerosols of health effects concerns are of fi-
brous and aggregate geometric shapes. The sites of
deposition in the human respiratory system are primar-
ily related to the mass median aerodynamic diameters
of inhaled particle size distributions. Therefore, to
assess potential exposure hazards it is necessary to
have accurate kinetic classifications of airborne panic-
ulate matter. Centrifugal spectrometers give direct and
continuously graded measures of the aerodynamic
size distributions of sampled aerosols. A mathematical
description of particle behavior in spiral channel centri-
fuges has been presented, and substantiated by com-
parisons with laboratory calibration data using polysty-
rene latex spheres. Here, the theory is extended to
non-spherical forms by incorporating appropriate dy-
namic particle shape resistance factors in trajectory
equations. It is demonstrated how optimum centrifuge
performance is made possible by the a priori determi-
nation of favorable operating conditions permitting
high-resolution characterization; specifically for fibrous
aerosols.

The exfoliated-cell micronucleus (MN) assay was used
to assess cytogenettc effects of exposure to radon
progeny and cigarette smoke among 99 Colorado pla-
teau uranium workers. Subjects were selected at
random from employees in underground and open-pit
uranium mines, ore mills, laboratories, and offices par-
ticipating in a sputum screening program from 1964-
88. The prevalence of cells with MN was determined
by scoring one sputum specimen for each worker.
Data obtained by interview were used to classify expo-
sure to radon progeny and smoking at the time sputum
specimens were taken. Underground miners were con-
sidered exposed to radon progeny, and others were
considered unexposed. Neither radon progeny expo-
sure nor cigarette smoking had any appreciable effect
on the prevalence of cells with MN; crude prevalence
ratios were 1.0 (95% Cl 0.7-1.4) and 0.9 (95% CE 0.6-
1.3), respectively. The effects of radon and smoking
were not confounded by each other or by age, and
there was no evidence of synergy between exposures.
The findings appear to cast doubt on the epidemiologi-
cal utility of a sputum-based MN assay for studies of
other populations exposed to occupational or environ-
mental lung carcinogens.

To eliminate between-tests error in longitudinal stud-
ies, for specimen sharing, convenient scheduling, etc.,
it is necessary to freeze freshly separated leukocytes
as well as non-transformed, continuous T lymphocyte
(CTL) lines. To test the efficacy of a programmable
freezer (temperature falls at an optimal rate), freshly
isolated lymphocytes and CTLs were each aliquoted
into three sets of vials. The cells were thawed and/or
washed and assayed for viability and T helper (T(sub
h)0/T suppressor (T(sub s)) ratio. It is clear that oma-
dequate freezing non-randomly damages cells of T cell
subpopulations, T(sub h) being more sensitive than
T(sub s). Further, it is proved that inadequate cryopre-
servation can confound results from a number of as-
sessment methods owing to morphological and func-
tional damages. The Battery of Leukocyte Tests (BLT)
under development in the laboratory is designed to
detect toxic, immunotoxic and genotoxic effects of in
vivo mutagens exposure to human blood.

When (36)CI-N-cholorpiperidine (NCP) (300 mg/L as
CI2) was mixed with stomach fluid from laboratory rats
(fasted either 24 or 48 hr) and incubated in the dark for
30 min at 37 C and at higher pH values, approximately
one-third was reduced to chloride and between 7%
and 63% of the radiolabel was found to chromato-
graph in a manner distinctly different from (36)CI-chlo-
ride of (36)CI-NCP. The new fraction is referred to as
the (36) Cl-chloroorganic fraction. The remainder of
the radiolabel was associated with (36)CI-NCP. Vary-
ing concentrations of (36)CI-NCP (3-200 mg/L as CI2)
have been incubated for 30 min at 37 C with stomach
fluid at varying pH on the product distribution. At low
pH values a threshold concentration of approximately
100 mg/L active chlorine was measured below which
all chloramine was reduced to (36)CI-chloride. As the
pH and concentration of (36)CI-NCP were increased,
the percentage of chloramine reduced to chloride de-
creased. Using concentrations between 110 and 120
mg/L (CI2) 7% and 4% of the label was associated
with the (36)CI-chloroorganic fraction at pH 7.1 and at
pH 2.2, respectively.

Both transduction of single chromosomal loci and co-
transduction of closely linked loci were observed be-
tween lysogenic and nonlysogenic strains of Pseudo-
monas aeruginosa in a freshwater habitat. Transduc-
tants were recovered at frequencies of 10 to the minus
6 to 10 to the minus 5 transductants per CPU. Trans-
ductants of lysogenized strains were recovered 10- to
100-fold more frequently than were transductants of
nonlysogenic parents. Lysogens are thus capable of
introducing phages which mediate generalized trans-
duction into the natural microbial community and serv-
ing as recipients of transduced DNA. It would appear
that lysogeny has the potential of increasing the size
and flexibility of the gene pool available to natural pop-
ulations of bacteria. The ability to generate and select
new genetic combinations through phage-mediated
exchange can be significant in the face of a continually
changing environment and may contribute to the ap-
parent fitness of the lysogenic state in natural ecosys-
tems. (Copyright (c) 1990, American Society for Micro-

Use of toxicity test data for population-level risk as-
sessment was investigated as follows: (1) the influ-
ence of life history characteristics of menhaden and
striped bass on vulnerability of contaminant-induced
stress; (2) the importance of test data availability; and
(3) the influence of exploitation intensity. Menhaden
and striped bass differed in terms of their capacity to
sustain the same level of contaminant-induced mortali-
ty. Changes in exploitation intensity affect the re-
sponses of both populations to the same level of addi-
tional contaminant-induced mortality. However, the
quantitative effects of both factors were small com-
pared to the uncertainty associated with estimating
long-term effects from short-term tests or QSARs.

Establishing the relationship between a given chemical
exposure and human reproductive health risk is com-
plicated by exposures or other concomitant factors
that may vary from pregnancy to pregnancy. Moreover,
when exposures are to complex mixtures of chemicals,
varying with time in number of components, doses of
individual components, and constancy of exposure,
the picture becomes even more complicated. A pilot
study of risk of adverse reproductive outcomes among
male wastewater treatment workers and their wives is
described. Wives of 231 workers were interviewed to
evaluate retrospectively the outcomes of spontaneous
early fetal loss and infertility. In addition, 87 workers
participated in a cross-sectional evaluation of sperm/
semen parameters. Due to the ever-changing nature
of exposure and lack of quantification of specific expo-
sures, six dichotompus variables were used for each
specific job description to give a surrogate measure of
exposure. Hence, no quantitative exposure-response
relationships could be modeled. These six variables
were independently assigned by two environmental
hygienists, and their interrater reliability was assessed.
Results are presented and further innovations in statis-
tical methodology are proposed for further applica-
tions.

2,4-Dithiobiuret (DTB) exposure causes a delayed
onset muscle weakness in rats that has been attrib-
uted to depressed neuromuscular transmission. The
present study compares the effects of DTB on both
sensory and motor function in rats. Adult male Long-
Evans hooded rats were exposed to saline, 0.25, 0.5,
or 1.0 mg/kg/day DTB, ip, for 5 consecutive days
(Days 1-5). Body weights were monitored throughout
the experiment. Motor activity was measured for 1 hr in
figure-eight mazes on Days 0, 6, 13, and 27. Forelimb
and hindlimb grip strength were assessed on Days 6,
13, and 27. Auditory thresholds were determined for 5-
and 40-kHz tones using reflex modification of the star-
tle response on Days 0, 7, 14, and 28. Visual function
was examined on Day 6 in animals exposed at 0.5 mg/
kg/day using flash- and pattern-elicited visual evoked
potentials (FEPs and PEPs, respectively). Thermal
sensitivity was measured using the hot plate proce-
dure. All motor endpoints were decreased in a dosage-
and time-dependent manner; the higher the dosage
the longer the effects lasted. There were no effects on
any measure of sensory function with the exception of
peak N2 of the FEP. Both the amplitude and latency of
FEP N2 were altered by DTB exposure. Decreases in
body weight were maximal on Day 9 at 1.0 mg/kg/day
(20% from control), but recovered by Day 22. (Copy-

Behavioral effects of organophosphates (OPs) typical-
ly decrease with repeated exposure, despite persist-
ence of OP-induced inhibition of acetylcholinesterase
(AChE) and downregulation of muscarinic acetylcho-
line (ACh) receptors. To characterize this tolerance
phenomenon, rats were trained to perform an appeti-
tive operant task which allowed daily quantification of
working memory (delayed matching-to-position), refer-
ence memory (visual discrimination) and motor func-
tion (choice response latencies and inter-response
times (IRTs) during delay). Findings indicate that ani-
mals showing a definitive sign of tolerance to OP ad-
ministration (subsensitivity to a cholinergic agonist)
were also functionally impaired on both the motoric
and mnemonic demands of a working memory task.
The nature of this impairment suggests further that it
results from compensatory changes in the CNS, e.g.,
muscarinic receptor downregulation, considered to
produce 'tolerance' to OPs in exposed animals.

A functional observational battery (FOB) was utilized
to assess the effects of 3-day exposure to the formam-
idine pesticide amitraz in outbred Sprague-Dawley de-
rived and inbred Fischer-344 derived (F344) rats (both
from Charles River Laboratories), and in outbred Long-
Evans rats obtained from two commercial suppliers
(Charles River Breeding Laboratories and Blue Spruce
Farms). Significant strain and stock differences were
obtained in baseline values for one-third of the FOB
measures. Characteristic signs of amitraz exposure
consisting of increased excitability, hyperreactivity,
and physiological and autonomic changes, were evi-
dent in all treated rats. These effects increased with
repeated dosing, and many were still present 6 days
after dosing. On individual measures, there were differ-
ences between the strains and stocks in terms of sen-
sitivity and time course of amitraz effects. In general,
Blue Spruce Long-Evans rats displayed more effects
of amitraz and F344 rats recovered more quickly than
others. On the other hand, Sprague-Dawley rats
showed the largest increases in the sensorimotor re-
sponses to stimuli.

In vivo assessment of toxicant action on Leydig cell
function is subject to homeostatic mechanisms which
make it difficult to determine whether any changes
seen in serum testosterone (T) concentration are due
to extragonadal endocrine alterations or to a direct
effect on the Leydig cell. Studies used a testicular cell
culture technique to evaluate Leydig cell testosterone
biosynthesis in the presence of several metal cations.
To determine the site of toxic action, the Leydig cells
were stimulated to produce testosterone by using
human chorionic gonadotrophin (hCG), dibutyl cyclic
adenosine monopnosphate (db cAMP) or several sub-
strates required for the biosynthesis of testosterone.
Ca(2+), Cr(3+), Fe(3+), Mg(2+), Na(1 +) or Pb(2+)
had no effect on stimulated testosterone. Dose re-
sponse depression in both hCG and db-cAMP stimu-
lated testosterone production were seen with Cd(2+),
Co(2+), Cu(2+). Hg(2+), Ni(2+), and Zn(2+) treat-
ment Surprisingly several of the metal cations which
caused a depression in hCG and db cAMP stimulated
testosterone production caused significant increases
in HCHOL and PREG stimulated testosterone produc-
tion over untreated and similarly stimulated cultures.

The article examines the pharmacokinetic behavior of
environmental chemicals and drugs that are altered
during aging. Absorption may be the least sensitive pa-
rameter to age-related perturbations. However, pulmo-
nary and dermal absorption, which are both dependent
upon passive diffusion, do appear to decline. In con-
trast, no evidence supports a decrease in passive
transport across the gut wall, while active processes in
the Gl tract do decline in the aged. Distribution is af-
fected by changes in body composition, the decrease
in lean body mass resulting in a decreased Vd for
water-soluble chemicals and enhanced persistence of
lipophilic ones. Changes in protein binding and blood
flow also alter the concentration of unbound chemicals
reaching the target site. The changes in metabolism
are extremely complex, with increases, decreases,
and no change being observed for different enzymes
with varying substrates in different tissues, sexes,
strain, and species. Only excretion tends to consistent-
ly change with age, in large part due to the altered
blood flow, structure, and physiology of the kidney. He-
patic and pulmonary elimination also tend to decline
with age.

Forced expiratory volume in 1 second (FEV1) was
measured in 21 men exercising while exposed to four
O3 concentrations (0.0, 0.08, 0.10, and 0.12 ppm). A
lognormal multiple linear regression model was fitted
to their mean FEV1 measurements to predict FEV1
percent decrease as a function of O3 concentration
and exposure duration. The exercise level used was
probably comparable to heavy manual labor. The long-
est O3 exposure studied was 6 h. Extrapolating cau-
tiously to an 8-h workday of heavy manual labor, the
model predicts that O3 concentrations of 0.08, 0.10,
and 0.12 ppm would decrease FEV1 by 9, 15, and 20
percent respectively. (Copyright (c) 1991 Air & Waste

Using a combination of IR and UV techniques, evi-
dence is presented for inclusion complex formation
between mucqchloric acid and B-cyclodextrin in acidic
aqueous solutions. UV evidence supports the conclu-
sion that under these acidic conditions mucochloric
acid-B-cycjodextrin complex could be isolated by re-
crystallization of a 1:1 mole ratio of the above com-
pounds from water at pH2. Solid sample IR (KBr or
nujol) showed a carbonyl shift of approximately 20
cm(sup minus 1) when mucochloric acid was com-
pared to the mucochloric acid-B-cyclodextrin complex.
No such shift was found upon simply grinding together
the above components. Thus the carbonyl shift is as-
cribed to inclusion complexation of mucochloric acid
into the B-cyclodextrin cavity. Melting point and thin
layer chromatographic analyses also yield supporting
evidence for the formation of solid mucochloric acid-B-
cyclodextrin complexes. Pilot studies with 3-chloro-4-
(dichloromethyl)-5-hydroxy-2(5h)-furanone (MX), sug-
gest a similar B-cyclodextrin-complex formation in

The midcycle surge of luteinizing hormone (LH) from
the pituitary provides the physiological trigger in the
mammalian female for the process of ovulation. Ac-
cordingly, any agent that compromises the LH surge
could function as a reproductive toxicant The acari-
cide chlordimeform (CDF) has previously been found
to decrease serum LH, probably by altering the hypo-
thalamic noradrenergic transmitter control of LH se-
cretion. Consequently, the present study focused on
the effect of acute CDF administration on the appear-
ance of the induced LH surge. Single intraperitoneal in-
jections of CDF (0,10,25,50 mg/kg) in OVX, estradiol
- implanted female Long-Evans rats approximately 5
hrs prior to the expected surge caused a complete
suppression at 25 and 50 mg/kg. Ten mg/kg had no
effect on surge amplitude, but advanced the LH peak
by 2 hrs. Since CDF has been found to elevate serum
cprticosterone (CORT), 10 mg CORT/rat were given at
different times prior to the surge. Following 20 hrs of
CORT exposure, only a partial lowering was seen; 5
hrs exposure were ineffective, indicating an indirect
adrenal effect was not the principal route, but may ac-
company an action of CDF on the hypothalamic mech-
anisms regulating the surge.

Recent evidence suggests that prolonged exposures
of exercising men to 0.08 ppm ozone (O3) result in sig-
nificant decrements in lung function, induction of respi-

reactivity. The purpose of the study was to confirm or
refute these findings by exposing 38 healthy young

jects performed exercise for a total of 5 h, which re-
quired a minute ventilation of 40 I/mm. Significant
(O3)-induced decrements were observed for forced
vital capacity (FVC, -0.25 1), forced expiratory volume
in 1 s (FEV(sub 1.0), -0.351), and mean expiratory flow
rate between 25% and 75% of FVC (FEF(sub 25-75), -
0.57 l/s), and significant increases were observed in
airway reactivity (35%), specific airway resistance
(0.77 cm H2O/S), and respiratory symptoms. These re-
sults essentially confirm previous findings. A large
range in individual responses was noted (e.g., percent-
age change in FEV(sub 1.0): 4% increase to 38% de-
crease). Responses also appeared to be nonlinear in
time under these experimental conditions.

The study used the polymerase chain reaction (PCR)
to speed the processing of revertants of Salmonella ty-
phimurium TA98 for DNA sequence analysis. Briefly, a
crude DNA extract from a single colony was prepared
and used in an asymmetric PCR to amplify a 228-bp
fragment containing the hisD3052 mutation approxi-
mately in the center. Following ultra-filtration, the
ssDNA was sequenced using an end-labeled probe
and dideoxy sequencing. The most frequent mutation
among the revertants was a -2 deletion of GC or CG
within the sequence CGCGCGCG, which is upstream
of the hisD3052 mutation. The deletion occurred in
38% (6/16) of the spontaneous (-S9) revertants and in
94% (15/16) of a set of 1-nitropyrene-induced rever-
tants. Misalignment of complementary DNA strands
within this repeat may account for this mutation, al-
though the possible formation of Z-DNA within this
region may also play a role. Other mutations, mostly
deletions but also some complex mutations (inser-
tions/deletions/substitutions), occurred within quasi-
palindromic regions of DNA. The potential DNA sec-
ondary structures within such regions may mediate the
templated production of some of these mutations.

Methods are described for toxicity testing of water and
sediment with two varieties of the freshwater marsh
plant Echinochloa crusgalli (Linneaus) Palisot de
Beauvois (Poaceae), and complex effluents. Two tests
are described: a seed germination and early seedling
growth test in water, and a survival and seedling
growth test in natural and synthetic sediments. Effects
of effluents from a sewage treatment plant, tannery,
textile mill, pulp and paper mill, coking plant and
sewage treatment plant included inhibition of germina-
tion, chlorophyll synthesis and growth. The tests with
rooted marsh plants were sensitive to pollutants and
detected toxicity of a range of pollutants in water and
sediment. Synthetic sediments similar to natural sedi-
ments allowed toxicity tests to be done under carefully
controlled conditions of particle size distribution, or-
ganic content, pH, electrode potential (Eh) and cation
exchange capacity (CEC).

Evaluation of the water quality of the southwest portion
of Lake Michigan is based on standards as set by the
Illinois Pollution Control Board (35 IL Adm Code 302).
Because it is a unique and invaluable resource, Lake
Michigan is protected to a higher level than other lakes
in the State. Its waters are required to meet: Lake
Michigan Standards, General Use Standards and
Public and Food Processing Water Supply Standards.
Additionally, a criterion for beach closure was also
used in the evaluation (IDPH, 1987). The Executive
Summary covers data for the current year only. Sec-
tion B of the report entitled 'Water Quality Trend Analy-
sis', contains data for the period 1970-88. The water
quality of the Illinois area of Lake Michigan has im-
proved substantially since the 1960's and 1970's due
to diversion of municipal and industrial treated
wastewater discharges away from Lake Michigan to
the Des Plaines River Basin. Discharges along the Illi-
nois shore now consist primarily of cooling water and
some combined sewer overflows. Major sources of
pollutants along the Illinois shore of Lake Michigan are
atmospheric deposition, urban runoff and in-place con-
taminants.

In 1986 and 1987 the Illinois Environmental Protection
Agency and Illinois Department of Conservation con-
ducted a cooperative survey of 14 Shawnee National
Forest region streams in Southern Illinois. Monitoring
included collection of aquatic macroinvertebrates,
water quality, sediment chemistry, stream habitat, and
fish population samples. Biological, chemical, and
physical data collected during the Shawnee study re-
vealed an unusual assemblage of high quality streams
characterized by excellent biotic integrity and water
quality, and exceptional physical and aesthetic at-
tributes. Outstanding streams in the Shawnee National
Forest include Big, Lusk, and Big Grand Pierre Creeks
in the Ohio River watershed and upper Clear and Miller
Creeks in the Mississippi River watershed. Streams ex-
hibiting lowest quality included lower Bay Creek, Bay
Creek Ditch, and Cedar Creek in the Ohio drainage,
and the lower Clear Creek continuum near the Shaw-
nee's western edge. High quality streams were gener-
ally located in the Shawnee Hills or Ozark Natural Divi-
sions; low quality streams were generally located in
agricultural bottomlands.

The paper evaluates and interprets the updated scien-
tific and technical information that EPA staff believes is
most relevant to the review of the primary (health) and
secondary (welfare) national ambient air quality stand-
ards for lead. The assessment is intended to bridge
the gap between the scientific review in the EPA crite-
ria document and the judgements required of the Ad-
ministrator in setting the ambient air quality standards
for lead. The major recommendations of the staff
paper are: (1) the range of standards under consider-
ation should be from 0.5 to 1.5 microg/cu m; (2) a
monthly averaging period would better reflect chil-
dren's responsiveness to lead exposures than a quar-
terly averaging period; (3) the most appropriate form of
the standard is the second highest monthly average in
a 3 year span; (4) with a monthly averaging period,
more frequent sampling is needed in areas with point
sources; and (5) the hi-volume sampler should be re-
tained to monitor compliance with the lead NAAQS.

readily available for determining the hydraulic conduc-
tivity of soils compacted in the field. Hydraulic conduc-
tivity test methods currently used on soil liners were
evaluated for their ability to meet the minimum require-
ments for field tests; i.e., that the test be capable of
measuring hydraulic conductivities at least as low as 1
x 10 to the -9th power m/s and that the values ob-
tained be representative of the overall soil liner. Of the
few methods capable of meeting the minimum require-
ments, even fewer are both practical to use and rarely
give false low values. Based on the advantages of the
methods evaluated, the best and most practical cur-
• r available technologies for evaluating hydraulic

Reid and laboratory toxicity tests were conducted on
the grass shrimp, Palaemonetes pugip, to evaluate the
usefulness of laboratory testing in estimating mortality
from fenvalerate exposure associated with agricultural
runoff. The study examined an integrated approach for
assessing the impacts of fenvalerate on estuarine
fauna, using 96-h static-renewal and 6-h pulsed-dose
laboratory toxicity tests and in situ toxicity tests. The
laboratory toxicity tests with fenvalerate gave 96-h
LC50 values ranging from 0.007 to 0.071 microgram/L
and 6-h PDLC50 values ranging from 0.100 to 0.130
microgram/L. Comparisons of the results of two field
toxicity tests with laboratory-derived LC50 values
snowed good agreement between field and laboratory
toxicity data. The variation between field and laborato-
ry toxicity tests may have been due to the limitations ot
the water sampling regime used in characterizing the
pesticide exposure during the field toxicity tests. These
comparisons suggest that a combination of laboratory
and field toxicity testing is required to estimate the
actual field mortality from fenvalerate exposure associ-
ated with agricultural runoff. Future studies should in-
clude composite water sampling and more frequent
discrete sampling methods to better characterize field
exposure regimes. (Copyright (c) 1989 SET AC.)

It is well known that protection of human health and
the environment from the risks of hazardous wastes in-
volves evaluation of numerous complex issues. Ap-
proximately 4 years ago a few people began to explore
the possibility of using expert system techniques to ex-
pedite the transfer of professional decision expertise
to a wider audience of decision makers. Currently sev-
eral organizations are developing expert systems to
expedite hazardous waste decision making and im-
prove the quality and consistency of resulting deci-
sions. It is anticipated that system development will
proliferate during the next few years. Expert systems
will change the way in which information is passed be-

The presence of biodegradable organic matter in
drinking water can result in biologically unstable water
that has been linked to various taste, odor and color
problems. When the implicated bacteria are members
of the total coliform group, those occurrences can
result in major compliance violations. The amount of
biodegradable organic matter in potable water is diffi-
cult to measure. The measurement of biodegradable
matter in drinking water is an operationally defined pa-
rameter and can only be expressed in relative terms.
The use of bioassay assays can provide important in-
formation regarding the nutrient status of water.

Low dispersal and sexual selection are characteristic
of the coastal polychaete Nereis acuminata Ehlers
1868 (also known as Nereis arenaceodentata Moore
1903 and Nereis (Neanthes) caudate Delle Chiaje

between populations of the polychaete. Four North
American populations were used, two from the Atlantic
and two from the Pacific. Worms from all sites (1) were
collected in 1987 and 1988 from the same habitat
type, (2) were morphologically similar and keyed out as
N. acuminata, and (3) reproduced monogamously and
exhibited male parental care, an extremely rare repro-
ductive mode in marine invertebrates. Results suggest
strongly that the Atlantic and Pacific populations have
been allopatric for a long time, and are different spe-

A common method of detecting a small leak in a pres-
surized underground storage tank pipeline system
containing petroleum is to monitor the pressure in the
line. A leak is declared if the pressure drops below a
specified threshold pressure. Small changes in the
temperature of the product in the line also produce
large changes in pressure which can easily exceed
those of a small leak. The paper presents theoretical
models to predict the pressure changes associated
with leaks and product temperature changes in pres-
surized pipelines. These models have been validated
in experiments at retail petroleum facilities and the
EPA's UST Test Apparatus. The magnitude of the
product temperature changes that can be expected
during a pressure test at a retail station is predicted
from a heat conduction model. The model includes the
effects of product delivery and product dispensing and
uses experimentally determined values of thermal dif-
fusivity for the product in the pipeline and for the gravel
and soil around the pipeline.

volunteers were found to inhibit replication of Crypto-
cpccus neoformans. Conditions under which fungista-
sis occurred were different than those required for
mouse peritoneal macrophage-mediated fungistasis.
Inhibition of fungal replication by mouse peritoneal ma-
crophages (MPM) requires that the macrophages are
activated and that the cocultures of C. neoformans
and macrophages be done in the presence of serum,
L-arginine, and endotoxin. HAM-mediated fungistasis
was not enhaced by endotoxin or by recombinant
human interferon-gamma (rHIFN-gamma). The combi-
nation of endotoxin and rHIFN-gamma inhibited the
fungistatic effect of HAM. Human peritoneal macro-
phages (HPM) from women undergoing laparoscopy
were tested for fungistasis and L-arginine nitrogen oxi-
dation. Partial inhibition of cryptocpccal replication oc-
curred; however, there was no evidence of L-arginine
metabolism to NO2- or NO3-. The absence of L-argi-
nine-dependent nitrogen oxidation in HAM and HPM,
compared to MPM, during conditions under which fun-
gistasis occurs suggests that the phenomenon is spe-
cies specific rather than specific to the tissue origin of
the macrophages.

Northern bobwhite, Colinus virginianus, were orally
dosed with the organophosphorus insecticide Chlor-
pyrifos to examine effects on brain Cholinesterase
(AChE) activity. Twp-week-old quail wera acutely ex-
posed and euthanized at selected times following
gavage-dpsing, ranging from 1 to 120 h later. The
AChE activity was determined in treated birds and
compared to concurrently tested control (corn oil)
birds. It was found that a lag time of 2 to 4 h following
dose exposure was necessary to detect significant
AChE depression caused by Chlorpyrifos. The lowest
dose that produced ChE to detect significant ChE de-
pression in these tests was between approximately 30
and 50 mg chlorpyrifos/kg body weight, with some
mortality occurring at the high end of that range. De-
pression typically persisted for at least 24 h.

A total of 1648 waterbome outbreaks and 446,377
cases of waterbome disease have been reported in
the United States since 1920. During the most recent
period, 1981-1988, 248 waterbome outbreaks oc-
curred in community (45%) and noncommunity (34%)
water systems and from the ingestion of contaminated
water from individual (11%) and recreational (10%)
water sources. The average annual number of out-
breaks reported in the period are only slightly less than
reported during the previous period, 1971 -1980, and is
comparable to that reported during 1931-1950. Al-
though, several large outbreaks have recently been re-
ported, most waterbome outbreaks since 1971 have
occurred in small community and noncommunity water
systems. The average number of cases of waterbome
disease per outbreak during 1971 -1988 is less than re-
ported during 1920-1940 but more than reported
during 1941-1960.

Exposure of Humans to Ambient Levels of Ozone
for 6.6 Hours Causes Cellular and Biochemical
Changes In the Lung. Journal article.

An acute (2h) exposure of humans to 0.4 ppm ozone
initiates biochemical changes in the lung resulting in
the production of components which mediate inflam-
mation and acute lung damage as well as components
which have the potential to lead to long term effects
such as fibrosis. However, many people are exposed
to lower levels of ozone than this, but for periods of
several hours. Therefore, it is important to determine if
a prolonged exposure to low levels of ozone is also ca-
pable of causing cellular and biochemical changes in
the lung. Non-smoking males were randomly exposed
to filtered air and either 0.10 ppm ozone or 0.08 ppm
ozone for 6.6 h with moderate exercise (40 1/min).
Bronchatveolar lavage (BAL) was performed 18 h after
each exposure, and cells and fluid analyzed. The BAL
fluid of volunteers exposed to 0.10 ppm ozone had sig-
nificant increases in neutrophils (PMNs), protein,
PGE2, fibronectin, interieukin-6 (IL-6), and lactate de-
hydrogenase (LDH) compared with BAL fluid from the
same volunteers exposed to filtered air. The study
concludes that exposure of humans to low levels of
ozone is sufficient to initiate an inflammatory reaction
in the lung.

The Surface Impoundment Modeling System (SIMS)
estimates volatile organic compound (VOC) emissions
and toxic air pollutant emission from surface impound-
ments and collection system emponents individually or
in series. It can be used to estimate emissions from
wastewater sources at hazardous waste treatment
works, storage and disposal facilities (TSDFs), publi-
cally owned treatment works (POTW's), and industrial
wastewater treatment facilities. The minimum informa-
tion required to use SIMS is the type of device to be
modeled, the total flow to the device, the total surface
area of the device, and the type of industry discharging
wastewater to the device. Default values for water dis-
charged from typical industries are supplied by the pro-
gram. The user can adjust these default values to
match their particular system. The SIMS is a personal
computer based program designed to estimate the air
emissions from surface impoundments. The emission
estimates are based on mass transfer models devel-
oped by the Emissions Standards Division (ESD) of
EPA during the evaluation of hazardous waste treat-
ment, storage, and disposal facilities (TSDF's). SIMS
allows the user to specify all the required inputs to
these emission models when the information is avail-
able, or when only limited information is available, pro-
vides default values for most of the model inputs.

The FATE Model has been developed for predicting
the fate of organics in a completely mixed activated
sludge treatment plant operated under acclimated
conditions. It has been validated using experimental
data from a pilot-scale facility and full-scale treatment
plants. The biogradation kinetic constants for some
compounds were estimated using group contribution
approach. Applications of the model include (1) as-
sessment of emissions of volatile organic compounds
from wastewater treatment plants, (2) estimation of the
concentration of toxic compounds associated with
sludges, and (3) a general framework for estimating
the removal of toxic compounds during conventional
primary/activated sludge treatment.

Ozone Isopleth Plotting Package (Research Version)
(OZIPR) is a trajectory-based air quality simulation
model that can be used with complex chemical kinet-
ics mechanisms to relate ozone concentrations to ini-
tial levels of organic and oxides of nitrogens (NOx) pre-
cursors. OZIPR is based on previous versions of EPA's
Ozone Isopleth Plotting Program, but it contains im-
proved and expanded capabilities that make the model
useful for research purposes. It serves the dual pur-
pose of providing: (1) a simple moving box model ca-
pable of using detailed chemistry, emissions and vari-
ous meteorological parameters to predict oxkJant for-
mation and (2) procedures through which the Empirical
Kinetics Modeling Approach (EKMA) can be imple-
mented for calculating emission reductions needed to
achieve the National Ambient Air Quality Standard for
ozone. The program is designed to run on an IBM PC/
AT or fully compatible personal computer. The soft-
ware package includes the executable program as well

Section 313 of the Emergency Planning and Communi-
ty Right-to-Know Act (also known as Title III) of the Su-
perfund Amendments and Reauthorization Act of 1986
(Public Law 99-499) requires EPA to establish a Na-
tional Inventory of toxic chemical emissions from cer-
tain facilities. The final Toxic Chemical Release Form
R and regulations for the 1987 reporting year were
published in the Federal Register on February 16,
1988 (53 FR 4500-4554). The list 9) toxic chemicals
subject to reporting consisted initially of chemicals
listed for similar reporting purposes by the States of
New Jersey and Maryland. There are over 300 chemi-
cals and categories on these lists. The reporting re-
quirement applies to owners and operators of facilities
that have 10 or more full-time employees, that are in
Standard Industrial Classification (SIC) codes 20
through 39 (i.e., manufacturing facilities) and that man-
ufacture (including importing), process or otherwise
use a listed toxic chemical in excess of specified
threshold quantities. The law mandates that the data
be made publicly available through a computer data-
base. The online TRI file should appeal to a broad
based user audience including industry, state and local
environmental agencies, emergency planning commit-
tees, the Federal Government and other regulatory
groups. Another important user group is likely to be
concerned citizens who, on their own or through public
interest groups and public libraries, can use TRI to ask
questions about chemical releases in their communi-
ties.

The Landfill Air Emissions Estimation Model is an aid
for local and state agencies in estimating landfill air
emission rates for nonmethane organic compounds
and individual air toxics. The program will also be help-
ful to landfill owners and operators affected by by the
upcoming New Source Performance Standard (NSPS)
and Emission Guidelines for Municipal Solid Waste
Landfill Air Emissions. The model is based on the
Scholl Canyon Gas Generation Model, used in devel-
opment of the soon-to-be-proposed regulation for
landfill air emissions. The Scholl Canyon Model is a
first order decay equation that uses site-specific char-
acteristics for estimating the gas generation rate. In
the absence of site-specific data, the program pro-
vides conservative default values from the sqon-to-be-
proposed NSPS for new landfills and emission guide-
lines for existing landfills. These default values may be
revised based on future information collected by the
Environmental Protection Agency.

Approximately 20 percent of the sites on the National
Priorities List (NPL) are municipal landfills which typi-
cally share similar characteristics. Because of the simi-
larity the Superfund Program anticipates that their re-
mediation will involve similar waste management ap-
proaches. As stated in the National Contingency Plan,
EPA expects that containment technologies will gener-
ally be appropriate for waste that poses a relatively low
long-term threat or where treatment is impracticable
(Sec. 300.430(a)(1)(iii)(B),55FR8846(March 8, 1990)).
In addition, EPA expects treatment to be considered
for identifiable areas of highly toxic and/or mobile ma-
terial that constitute the principal threat(s) posed by
the site (Sec. 300.430(a)(1)(iii)(A)). The similarity in
landfill characteristics and the NCR expectations make
it possible to streamline the RI/FS for municipal land-
fills with respect to site characterization, risk assess-
ment, and the development of remedial action alterna-
tives. The fact sheet outlines available streamlining
techniques for each of these three phases of an Rl/
FS. Additional information, including tools to assist in
scoping activities, will be included in the document
Conducting Remedial Investigations/Feasibility Stud-
ies for CERCLA Municipal Landfill Sites (November
1990, Directive No. 9355.3-11). The document will be

The Fact Sheet discusses the closing of the Old NPL
under the original HRS. Since 1982, the U.S. Environ-
mental Protection Agency (EPA) has been preparing
the National Priorities List (NPL). The list informs the
public of uncontrolled hazardous waste sites that war-
rant further investigation to determine if they pose risks
to public health or the environment. Such sites are eli-
gible for long-term 'remedial action' financed under the
Trust Fund established by the Comprehensive Envi-
ronmental Response, Compensation, and Liability Act
as amended by the Superfund Amendments and Re-
authorization Act of 1986 (SARA). Sites are placed on
the NPL primarily on the basis of their scores under
EPA's Hazard Ranking System (HRS) model devel-
oped in 1982. EPA has now revised the HRS in re-
sponse to SARA. The revised HRS, which will become
effective late in February 1991, 90 days after its publi-
cation in the Federal Register, is a more comprehen-
sive and accurate scoring system than the original
HRS and will add new types of sites to the NPL.

The Fact Sheet discusses the Hazard Ranking System
(HRS) in response to the Superfund Amendments and
Reauthorization Act of 1986 (SARA). The HRS is the
scoring system EPA uses to assess the relative threat
associated with the release or potential release of haz-
ardous substances from a waste site. The HRS score
is the primary criterion EPA uses to determine whether
a site should be placed on the National Priorities List
(NPL). The NPL identifies sites that warrant further in-
vestigation to determine if they pose risks to public
health or the environment. Sites on the NPL are eligi-
ble for long-term 'remedial action' financed under the
Comprehensive Environmental Response, Compensa-
tion, and Liability Act of 1980 (CERCLA), as amended
by SARA. SARA authorizes a 'Hazardous Substances
Superfund' totalling $8.5 billion over 5 years to pay
costs not assumed by those responsible for problems
at a site. The HRS uses data that can be collected rel-
atively quickly and inexpensively, thus allowing most
Superfund resources to be directed to remedial ac-
tions at sites on the NPL.

post signs at every Superfund site. Superfund sites
have been and will continue to be of interest and con-
cern to people in surrounding communities and to the
public in general. Through the posting of signs at each
site, the Superfund program can work to promote con-
tinued interaction with communities as well as assure
that interested parties can access information or

The Fact Sheet discusses the revised HRS which re-
tains the same cutoff score and basic approach as the
original HRS, while incorporating SARA requirements
as well as improvements identified as necessary by
EPA and the public. The revised HRS retains the
ground water, surface water, and air pathways, drops
the direct contact and fire/explosion pathways, and
adds a fourth pathway, soil exposure. Several key pro-
visions of the revised HRS make it more comprehen-
sive. Other provisions make the revised HRS more ac-
curate. The complexity and scope of the issues in-
volved in revising the HRS required EPA to get wide-
spread input. The majority of the commenters believed
that the revised HRS represented an improvement
over the original HRS. The result is a revised HRS that
is a practical and effective tool in identifying the na-
tion's worst hazardous waste sites.

The U.S. Environmental Protection Agency, as dis-
cussed in the Fact Sheet, has developed a Long-Term
Contracting Strategy for the Superfund program. The
Agency's objectives in developing the strategy were to
analyze the long-term contracting needs of the pro-
gram, and to design a portfolio of Superfund contracts
to meet those needs over the next ten years. This stra-
tegic planning effort was recommended by the 1989
Agency report on A Management Review of the Super-
fund Program.

The Fact Sheet discusses CERCLA remedial actions
which must comply with the requirements of the Re-
source Conservation and Recovery Act (RCRA) when
they are determined to be applicable or relevant and
appropriate requirements (ARARs) unless a waiver is
justified. For RCRA Subtitle C hazardous waste re-
quirements to be applicable, the CERCLA response
action must constitute either treatment, storage, trans-
port, or disposal of a RCRA hazardous waste. There-
fore, to make determinations about the applicability or
relevance and appropriateness of RCRA require-
ments, site managers need to understand how to iden-
tify whether a CERCLA waste is a RCRA hazardous
waste (including when a waste exhibits the newly pro-
mulgated toxicity characteristics (TC)). The purpose of
the guide, the second dealing with the TC rule (see
ARARs Qs & As, Compliance with the Toxicity Charac-
teristics Rule: Part I, May 1990, Publication 9234.2-

The Office of Emergency and Remedial Response
(OERR) issued a series of Superfund LDR Guides in
July and December of 1989. Since the issuance of
these guides, the Environmental Protection Agency,
with cooperation from outside parties (e.g., environ-
mental groups, industry representatives), has conduct-
ed an analysis of the potential impacts associated with
applying the LDR treatment standards to Superfund
and RCRA Corrective Action cleanups. As a result of
these analyses, it was decided that they Agency will
promulgate a third set of treatment standards (in addi-
tion to the wastewater and nonwastewater categories
currently in effect) specifically for soil and debris
wastes. In the interim, there is the presumption that
CERCLA response actions involving the placement of
soil and debris contaminated with RCRA restricted
wastes will utilize a Treatability Variance to comply
with the LDRs and that, under these variances, the
treatment levels outlined in Superfund LDR Guide 6B
will serve as alternative 'treatment standards' for re-
moval action. The guide has been prepared to outline
the process for obtaining and complying with a Treat-
ability Variance for soil and debris that are contaminat-
ed with RCRA hazardous wastes until such time that
the Agency promulgates treatment standards for soil
and debris.

The Fact Sheet discusses, section 121(d)(2) of
CERCLA, as amended by the 1986 Superfund Amend-
ments and Reauthorization Act (SARA), requires that
remedial actions must at least attain Federal and more
stringent State applicable or relevant and appropriate
requirements (ARARs) upon completion of the remedi-
al action. The Q's and A's fact sheet is designed to
provide guidance on the status of State ground-water
antidegradation provisions as potential ARARs for
CERCLA ground-water and soil remedial actions. The
guidance in the fact sheet reiterates Agency policy al-
ready in practice in EPA's Regional offices. The goal
and policy of the Superfund program is to return usable
ground water to its beneficial uses within the time-
frame that is reasonable, given the particular circum-
stances of the site. In addition to their goal of ground-
water cleanup, Superfund has a nondegradation policy
in that they strive for the prevention of further degrada-
tion of the ground water during their remedial actions.
However, it should be noted that more stringent State
standards than those imposed by EPA policy may be
imposed by State antidegradation requirements. Such
State requirements, if they have been determined to
be ARARs for the site, would have to be met (e.g., by
meeting the discharge requirements) or waived (e.g.,
fay the interim remedy waiver). Nevertheless, even
where temporary degradation of the ground water may
be required during the remedial action, they will pro-
vide protection by restricting access or providing insti-
tutional controls, and EPA response actions will ulti-
mately result in restoration of the ground water's bene-
ficial uses.

Reporting continuous releases of hazardous sub-
stances that equal or exceed a reportabie quantity
(RQ) has been required under the Comprehensive En-
vironmental Response, Compensation, and Liability
Act (CERCLA) since its enactment in 1980. Section
103(f)(2) of CERCLA provides that releases of hazard-
ous substances that are continuous and stable in
quantity and rate may be reported annually or when-
ever there is a statistically significant increase (SSI).
The purpose of the guidance document is to provide
assistance to the EPA Regions by discussing and
making recommendations regarding the options avail-
able for evaluating reports of continuous releases. The
effective implementation of the continuous release re-
porting regulation will depend largely on whether the
EPA Regions are able to fully and easily evaluate the
continuous release reports they receive.

the State received complaints concerning leachate
breakouts in the area and, by 1983 VOC-contamina-
tton had been identified in a domestic drinking water
well. The Record of Decision (ROD) addresses source
control and ground water contamination near the land-
fill. The selected remedial action for the site includes
excavating and consolidating approximately 2,000
cubic yards of wetlands sediment and 30,000 cubic
yards of solid waste and depositing the material into
the landfill prior to capping; collecting and treating
landfill gases using a thermal destruction process;
ground water pumping and treatment using chemical

The 12-acre Woodland Route 72 Dump site is an
abandoned hazardous waste dump in Woodland
Township, Burlington County, New Jersey. The site is
being remediated concurrently with another aban-
doned dump. Several chemical manufacturing firms
dumped chemicals and other wastes into trenches and
lagoons or burned the waste at the sites from the early
1950s to 1962. The primary contaminants of concern
affecting the surface soil, sediment, sludge, debris,
and ground water are VOCs including benzene, tolu-
ene, TCE and xylenes; organics including PAHs, pesti-
cides, and phenols; radionuclides (e.g., uranium and
thorium series); and metals including lead and chromi-
um. The selected remedial action for the site includes
excavation, further characterization, and offsite dis-
posal at a permitted facility of 54,000 cubic yards (total
from both sites) of contaminated surface soil, sludges,
debris and sediment; offsite disposal of 19 cubic yards
(total from both sites) of radiologically contaminated
surface materials including a drum of radioactive pel-
lets; ground water pumping and treatment with treat-
ment to be determined during design. The total esti-
mated present worth cost for the concurrent remedial
actions at the Route 72 and Route 532 sites is
$142,200,000.

The Radium Chemical site consists of a one-story
brick building in a light industrial/residential section in
Woodside, Queens County, New York. The Radium
Chemical Company (RCC) produced luminous paint
beginning in 1913 and later manufactured, leased, and
sold radium226 to hospitals, medical centers and re-
search laboratories. RCC abandoned the building with-
out complying leaving a large number of radium-con-
taining sealed devices, some of which were suspected
of releasing radium and radon gas. Also onsite were
hundreds of containers of laboratory chemicals. In
1989, a Public Hearth Advisory was issued for the site
based on the threatened release of radium226. The
selected remedial action for the site includes partial
decontamination and complete dismantling of the con-
taminated building, followed by offsite disposal of
debris as appropriate based on a contamination level;
excavation and offsite disposal of contaminated soil
and subsurface piping, followed by replacement of
piping and backfilling with clean soil; and treatment of
some radium-contaminated hazardous waste, fol-
lowed by offsite disposal of treated and untreated
radium-contaminated hazardous wastes in approved
facilities.

The 15-acre M.W. Manufacturing site is a former
copper recovery facility in Montour County, Pennsylva-
nia, two miles north of Danville. The initial remedial in-
vestigation revealed several areas posing potential
threats to public health: the carbon waste pile, four
wire-fluff waste piles, a surface impoundment, a buried
lagoon, and contaminated soil, drums and storage
tanks. A 1989 remedial action addressed the concerns
for direct contact with, and migration of contaminants
from, the carbon waste pile by excavating the carbon
waste pile and incinerating the waste offsite. The
second remedial action addresses the remaining prin-
cipal threats at the site by treating the onsite waste
and contaminated soil. A subsequent remedial action
will address possible remediation of contaminated
ground water and offiete soil, sediment and surface
water contamination. The primary contaminants of
concern affecting the soil, debris and lagoon water are
VOCs including PCE and TCE; other organics including
PCBs; and metals including lead.

water are VOCs including TCE and 1,1-DCE. The se-
lected remedial action for the site includes ground
water pumping and onsite treatment using air stripping,
followed by carbon adsorption as an ancillary treat-
ment step before onsite discharge of the treated
ground water; vapor-phased carbon adsorption treat-
ment of air stripper exhaust, followed by offsite dispos-
al or treatment of spent carbon and ground water mon-
itoring. The estimated present worth cost for this reme-
dial action is $1,345,000, which includes an estimated
annual O and M cost of $46,709 for 45 years.

The 7-acre Walsh Landfill site encompasses an ap-
proximately 1.5-acre landfill and surrounding area in a
heavily wooded region of Honeybrook Township,
Chester County, Pennsylvania. The landfill reportedly
received mixed municipal and industrial wastes for dis-
posal between 1963 and 1976; although State investi-
gations in 1979 revealed that disposal of hazardous
waste at the site had resumed after that period. The
primary contaminants of concern affecting soil, sedi-
ment, and ground water are VOCs including benzene,
PCE, and TCE; other organics including PAHs; and
metals including arsenic and lead. The selected reme-
dial action for the site includes removal of bulky items
and debris from the landfill surface for resource recov-
ery, followed by construction of an approximately 5.2-
acre landfill cap; provision of an alternate water supply
to approximately 50 residences by extending the mu-
nicipal water system; ground water monitoring; and im-
plementation of site access restrictions and institution-
al controls, including land use, ground water use, and
deed restrictions.

The 25-acre Lord-Shope Landfill site is an inactive
hazardous waste landfill in Girard Township, Erie
County, northwestern Pennsylvania. The site consists
of a 4-acre landfill and adjacent areas of contaminated
soil, surface water and ground water. The primary con-
taminants of concern affecting the landfill material,
surrounding soil, and ground water are VOCs including
benzene, PCE, and TCE; and metals including arsenic,
chromium, and lead. The selected remedial action for
the site includes in-situ vapor stripping using vacuum
wells to volatize and remove VOCs from the landfill
material and the surrounding soil; collection and treat-
ment of gas emissions generated by the vapor strip-
ping process using carbon filtration; ground water
pumping and treatment including pretreatment for
metal removal, followed by air stripping, to halt plume
migration, with final discharge of treated ground water
into the nearby surface tributaries; implementation of
site access restrictions and institutional controls in-
cluding ground water use restrictions. The estimated
present worth cost for the remedial action is
$5,760,000, which includes an annual O and M cost of
$420,000 for years 1 - 2 and $310,000 for years 3 - 50.

The Army Creek Landfill site, a former sand and gravel
quarry, is approximately two miles southwest of New
Castle, Delaware. The site abuts Army Creek/Pond
and high quality wetlands to the south and east and
lies adjacent to Delaware Sand and Gravel Landfill, an-
other Superfund site. From 1960 to 1968, when the
landfill reached capacity and closed. A 1986 Record of
Decision (ROD) provided for capping of the landfill and
for the continued operation of the recovery well net-
work to maintain the ground water divide. The extract-
ed ground water currently discharged into Army Creek
Pond untreated. The selected remedial action for the
site includes ground water pumping using the recovery
well network and treatment using a modified conven-
tional precipitation water treatment plant which in-
volves aeration, precipitation, sedimentation, and filtra-
tion followed by onsite discharge of the effluent to
Army Creek/Pond; sampling and disposal of sludge
generated during the treatment process; and monitor-
ing of the sediment, recovered ground water, surface
water, and wetlands. The estimated present worth
cost for the remedial action is $4,900,000 which in-
cludes an annual O and M cost of $294,000.

The Whitewood Creek site is a mine tailings deposit
area near the town of Whitewood in Lawrence, Mead,
and Butte counties, South Dakota. From 1877 to 1977,
arsenic-rich tailings from gold and ore mining and mill-
ing operations, conducted by the Homestake Mining
Company, were discharged directly into Whitewood
Creek. Residential soil contains arsenic contamination
as a result of a building in the tailings area. The select-
ed remedial action for the site includes removing and/
or covering frequently used areas with clean surface
soil (arsenic <20 mg/kg) in residential areas with ar-
senic levels above 100 mg/kg followed by disposal of
the arsenic-contaminated soil, if approved by EPA, and
revegetation of the remediated area; soil sampling at
all remediated areas to confirm that arsenic levels are
below 100 mg/kg. EPA is invoking ARAR waivers
based on the technical impracticability of remediating
contaminated ground and surface waters. The estimat-
ed present worth cost for the remedial action is
$882,813, which includes an annual O and M cost of
$12,000 for years 1 -5 and $6,000 for years 6-30.

The 11-acre Onalaska Municipal Landfill site includes
a 7-acre landfill owned by the Township of Onalaska,
which is located in central-western Wisconsin. The
Black River and its associated wetlands are 400 feet
west of the site and lie within a wildlife and fish refuge.
Approximately 320,000 gallons of liquid solvent waste
and approximately 1,000 drums of solvent waste were
either burned with other trash onsite or poured directly
into holes for burial in the southwestern portion of the
landfill. The primary contaminants of concern affecting
the soil and ground water are VOCs, including ben-
zene, toluene, xylenes, and TCE; other organics in-
cluding PAHs; and metals including arsenic and lead.
The selected remedial action for the site includes in-
situ bioremediation of the solvent-contaminated soil
and, if feasible, a portion of the landfill debris; pumping
and treatment of the ground water plume using aer-
ation, clarification, and filtration, followed by discharge
of the treated ground water into the Black River and

The Watkins-Johnson site is an active research and
development, manufacturing, and industrial complex in
Santa Cruz County, five miles north of Santa Cruz,
California. The Watkins-Johnson Company has owned
and operated the complex since 1963, conducting
such activities as: metal machining, degreasing, metal
plating, and photo laboratory activities. During these
activities, a variety of organics, inorganics and metals
were used. The primary contaminants of concern af-
fecting the soil and ground water are VOCs including
PCE and TCE, and metals including silver. The select-
ed remedial action for the site includes soil vapor
(vacuum) extraction with pretreatment of extracted
vapors using GAG prior to ambient discharge; capping
and grading contaminated soil areas to minimize the
potential for mobilization of soil contaminants to the
ground water; installing infiltration leachfields to pre-
vent offsite migration of ground water contaminants in
the perched zone; installing gravity drains to transfer
the contaminated ground water from the perched zone
to the regional aquifer zone for subsequent extraction;
ground water pumping and onsite treatment to remove
contamination from both the perched and regional
zones using GAC adsorption with offsite regeneration
of spent carbon. The estimated present worth cost for
this remedial action is $2,156,243, which includes an
estimated annual O and M cost of $167,820.

a September 30,1987 ROD that addressed the reme-
diation of onsite soil contamination using thermal de-
struction. EPA has determined that incineration of sur-
face soil will remove most of the insoluble contami-
nants present, and the Agency has determined that in-
situ soil washing or soil flushing should be tested as a
viable option to thermal destruction of subsurface soil
contamination. The primary contaminants of concern
affecting soil and ground water are VOCs including
benzene; other organics including PCBs and PAHs;
and metals including arsenic and lead. The selected
remedial action for the amendment is included.

The Tinkham's Garage site includes 375 acres of resi-
dential and undeveloped land in Londonderry, New
Hampshire. EPA site investigations in 1981 revealed
onsite soil and ground water contaminated with VOCs
resulting from onsite surface dumping of liquids and
sludge in 1978 and 1979. The major contaminated soil
area is in a field behind Tinkham's Garage. The first re-
medial action selected for the site was documented in
a 1986 Record of Decision (ROD), which included ex-
cavation of approximately 10,800 cubic yards of con-
taminated soil with onsite treatment using either ther-
mal aeration, composting or soil washing. Local wet-
lands impacted by soil excavating activities and con-
taminated ground water were also to be remediated.
Information generated during a pre-design study led
EPA in 1988 to propose the amendment to the 1986
ROD. As a result of the pre-design study findings, the
remedial action selected in the 1986 ROD was never
implemented. The primary contaminants of concern
affecting the soil and ground water are VOCs including
TCE and PCE. The selected remedial action for the
site is included.

The Teledyne Wah Chang (TWC) site, in Millersburg,
Oregon, is an active plant used to produce nonferrous
metals and products. The site consists of a 110-acre
plant site, which contains the plant's former sludge
ponds, and a 115-acre farm site, which contains four
active wastewater sludge ponds. Portions of the TWC
site are within the Willamette River's 100- and 500-
year floodplain. The Wah Chang Corporation began
operating a U.S. Bureau of Mines zirconium metal
sponge pilot plant under contract with the U.S. Atomic
Energy Commission in 1956. Additional facilities were
subsequently built near the plant beginning in 1957 to
produce nonferrous metals and products. The Lower
River Solids Pond (LRSP) and Schmidt Lake sludge
pond, which stored wastewater generated from the
plant operations, are being addressed by this remedial
action. The sludge in both the LRSP and Schmidt Lake
contains heavy metals, organic compounds, and trace
levels of radionuclides. The selected remedial action
for the site includes excavation of 85,000 cubic yards
of sludge with partial solidification of the sludge, fol-
lowed by offsite disposal in a permitted solid waste
landfill.

The 8-acre Coast Wood Preserving (CWP) site is an
active wood preserving facility in a rural, agricultural
area three miles south of Ukiah, California. Wood pre-
serving operations began at the site in 1971, and since
then near-surface soil contamination has occurred pri-
marily as the result of drippings. Investigations by CWP
beginning in the early 1970s revealed elevated chromi-
um and arsenic concentrations in near-surface soil and
elevated chromium concentrations in ground water
particularly near the main treatment and storage
areas. In addition, offsite migration of chromium has
occurred via ground water. A number of measures
have been implemented by CWP to improve overall
site conditions. Interim remedial measures were con-
ducted in 1983 to intercept and limit migration of chro-
mium in ground water. The primary contaminants of
concern for soil and ground water are metals including
arsenic and chromium. The selected remedial action
for the site includes paving exposed soil; onsite treat-
ment of soil after site closure in 10 years using the best
available technology at the time; plume control and aq-
uifer remediation via ground water pumping and reuse
in CWP's operations to the extent possible or electro-
chemical treatment of excess ground water which
cannot be recycled followed by discharge to the Ukiah
Sewage Treatment Plant and/or reinjection; ground
water monitoring; and development of a contingency
plan for offsite ground water remediation if needed.

The organochlorine pesticide, pentachlorophenol, a
potent sulfotransferase inhibitor, reportedly reduces
the binding of 2,6-dinitrotoluene, an industrial hepato-
carcinogen to hepatic DNA by 95% after a single i.p.
injection. Activation of 2,6-dinitrotoluene to genotoxic
metabolites involves enzymes in both the liver and the
intestinal flora. Since pentachlorophenol also has bac-
tericidal activity and induces hepatic mixed function
oxidase activity after longer treatment, the effect of
pentachlorophenol on intestinal enzyme activity and
the biotransformation of 2,6-dinitrotoluene to geno-
toxic metabolites was studied after 1, 2, 4, and 5
weeks of treatment. Male Fischer 344 rats were dosed
daily, by gavage, with either 20 mg/kg pentachloro-
phenol or the peanut oil vehicle. After 1, 2, 4, and 5
weeks, select control and treated animals were inject-
ed p.o. with 75 mg/kg 2,6-dinitrotoluene and trans-
ferred to metabolism cages, where urine was collected
for 24 hr and tested for nrmtagenic activity by the Ames
Salmonella typhimurium reversion assay.
