Activities: The Corvallis Environmental Research Laboratory sponsored the Inter- national Conference: Assessment of Crop Loss from Air Pollutants, Raleigh, NC, with participation of more than 170 research scientists. The confer- ence presented final results of EPA's National Crop Loss Assessment Program. The keynote address at the conference was presented by Dr. J. Craig Potter, Assistant Administrator for Air, Noise, and Radiation. The proceedings will be published in two peer-reviewed publications. General conclusions from the conference were: (1) ozone significantly reduces the growth and yield of many major agricultural crops; (2) potentially phytotoxic concentrations of ozone are widely distributed in agricultural areas; (3) in economic terms, the reduced yield costs the U.S. economy 2 to 4 billion dollars annually; (4) additional research is reouired to reduce the uncertainties in the estimate and to provide a physiological basis for extrapolating the results. Conference results will assist the Office of Air Quality Planning and Standards in development of a secondary national ambient air ouality standard for ozone. The NCLAN data synthesis project has finalized the data library, developed functional relationships for all data sets, and completed special analysis on several data sets. The data library contains the plant yield and air quality data from all NCLAN sponsored field data, as well as other associ- ated data. The Economic Assessment Group has completed analysis of the economic effects of ozone on the agricultural sector. The modeling procedures incorporate confidence intervals for the economic benefits which account ------- for uncertainty in both the exposure-response relationships and the underlying kriged ozone levels used in the analysis. Interactions with the Federal Farm Program have been modeled. Also included are adjustments for drought stress using the analysis developed by David King from the University of Portland and a weighting scheme for ozone exposure which incorporates adjustments both for differential growth rates during the season and for plantings by producers. On December 17, Gerald Emison, the Director of EPA's Office of Air Quality Planning and Standards (OAQPS) was briefed on the NCLAN Program (its purpose and accomplishments) and the need for future crops research. A presentation was made (December 14) to EPA's Clean Air Science Advisory Committee: A review and interpretation of new literature published since the Criteria Document for Ozone and other Photochemical Oxidants was issued and new analyses by CERL scientists to develop alternative ozone exposure indices relating ozone exposure to reduced crop yield. The alternative exposure indices were developed to assist OAQPS staff in determining the appropriate averaging time for a welfare (secondary) standard. Findings: Research was conducted to determine the impact of soil moisture stress on ozone sensitivity of crops. Goal of the analysis was to develop drought stress correction factors, through simulation modeling, to use in adjust- ing ozone-response functions for crops as a part of EPA's National Crop Loss Assessment (NCLAN) Program. Simulation modeling was used to derive yield correction factors from two models: one estimates the influence of soil moisture deficits on regional yield; the second predicts moisture stress x ozone interactions, The influence of soil moisture status on the progression of ozone damage was simulated along with the impact of ozone damage on the subsequent soil moisture. Model results were validated using data from drought x ozone interaction field studies from NCLAN. Model outputs were combined with measures of regional moisture stress to predict drought impacts on corn, soybean, wheat and cotton for the years 1979-83. Results predict an approximate 20% drought-induced reduction in crop sensitivity to ozone. An investigation into the combined effects ozone and soil moisture deficit on cotton yielded the following finding: (1) soil moisture deficit can decrease the impact of ozone on cotton yield and foliar injury; (2) the interaction of the two stresses did not signifi- cantly change seed quality. On irrigated farms, ozone can significantly reduce cotton yields, however, on non-irrigated farms ozone will impair yield only on years of average or more rainfall which eliminate the soil moisture deficit factor.

Determine the percentage, distribution, and characteristics of fishless lakes. Determine whether long term chemical and biological changes are occurring in lakes. Output Status: Progress report on status of regional case studies (Florida, north-central Wisconsin, Upper Peninsula of Michigan, and Adirondacks) on surface water characteristics relating to acid deposition (03/88). On schedule. Maps depicting pH, sulfate, and acid neutralizing capacity of Western lake populations (01/88). On schedule. Draft report on seasonal chemical variability in Eastern lakes (06/88). Data bases have been verified. Poor quality of some of the data may delay the final report. Activities: National Lake Survey, Phase I: Data analysis interpretations on the results of the Eastern and Western Lake Surveys continue. Two manuscripts were submitted this quarter and several additional manuscripts are in preparation. National Lake Survey, Phase II: The verified data base for the seasonal samples has been received and validation of this data base has been completed. Data analysis runs on the population estimates have been completed. Re-analysis of some samples is planned and further data inter- pretation will be delayed pending revision of the data base. The results of the Western Lake Survey were presented at the annual meeting of the American Water Resources Association (11/87). Findings: Lakes in wilderness areas of the western United States generally contain lower concentrations of acid neutralizing capacity, base cations, sulfate, and dissolved organic carbon than non-wilderness lakes in the same subregions. The results of the Western Lake Survey support earlier contentions that lakes in USFS wilderness areas are sensitive to a variety ------- of perturbations and warrant a conservative approach to managing these resources. Sensitivity of western lakes to acidification is difficult to predict on the basis of watershed factors because of local variations in geology and hydrology. Seasonal data for lakes monitored as long as seven years show that spring lakes chemistry can be predicted to a large degree using fall chemistry: 88% of the variance in spring acid neutralizing capacity could be accounted for on the basis of the fall data. Therefore, one of the major criticisms of the National Lake Survey has been resolved. Publications: Published: Blick, D. J., J. J. Messer, D. H. Landers, and W. S. Overton.

Critically evaluate the models used in the Direct/Delayed Response Project and the predictions/classifications derived from that project. Provide mechanistic data to refine/revise those models as necessary. Output Status: Progress report on Watershed Manipulation Project (12/87). Completed. Final report of DDRP model sensitivity and uncertainty analysis (06/88). On schedule. Progress report on the watershed manipulation project (12/88). On schedule. Journal article on residence time distribution of soil water on a hill- slope (12/88). On schedule. Activities: Experimental acid additions to the Field Manipulation Trial (FMT) plots were completed. Soil solutions have been analyzed for major chemical constituents; soil samples have been collected from the plots, and will be analyzed for pH, cation exchange capacity, exchangeable bases, and extract- able sul fate. Data collection has been initiated at two precipitation stations located at the recently established Bear Brook research site in southeastern Maine. Site selection criteria, field sampling protocols, and quality assurance methods are compatible with NADP. A radiotelemetry monitoring system is operating on a preliminary basis at Bear Brook. The network will allow remote programming, remote downloading of data, and real time data observation via modem. WMP cooperating scientists have completed chemical analyses of soils collected from the experimental plots located adjacent to the Bear Brook watersheds. The external experimental plots will be irrigated with various levels and combinations of sulfuric and nitric acids for an evaluation of dose response. WMP cooperating scientists have initiated a suite of laboratory experi- ments with a bulk, homogenized soil prepared from the Bear Brook site. Some of the experiments include examining effects of nitrification inhib- 19 ------- itors on solution chemistry, testing weathering slope constants, assessing excess ammonium addition on nitrification rates, and generating sulfate adsorption isotherms. ERL-C scientists compiled the first annual in-house progress report on the WMP. The report summarizes site development, research progress, initial .findings, and modeling activities associated with the Bear Brook study site. Findings: WMP scientists from the nitrogen and sulfur task groups evaluated the effects of handling procedures and methodology on the determination of sulfur in vegetation soil, and sediments. Experiments indicate that an automated S analyzer, when properly calibrated, yields precise and accurate measurements. Freeze-drying was found to cause less alteration in S constituents than air-drying. WMP scientists will apply these findings in subsequent experimental activities. In laboratory studies simulating snowmelt leaching of forest soils, nitric acid leached more aluminum than sulfuric acid from soil columns containing a forest floor-spodic horizon sequence thought to be highly sensitive to acidification by acid precipitation. The research suggests that the kind of acid leaching these horizons becomes important when predicting effects of acid deposition on surface water acidification. In a companion experiment, it was found that the presence of a forest floor in soil column leaching studies significantly increased the aluminum concentration leached from the mineral soil. The results demonstrate the importance of considering the chemical composition of soil leachates at the forest floor-mineral horizon boundary when evluating how acid precipi- tation effects aluminum concentration in drainage waters.

The workshop outlined QA/QC approaches taken for the National Surface Water Survey, and then prioritized major issues and discussed QA approaches. A preliminary summary of the workshop has been prepared. Actions to investigate the costs and benefits of various strategies for using biological information at various tiers of TIME were continued. Reports on the usefulness of each organismal group to detect surface water acidification and/or recovery were completed for five groups: fish, chrysophytes, diatoms, dinoflagellates, and blue-green and green algae. Similar reports were previously completed for zooplankton, periphyton, benthic invertebrates in lakes, and benthic invertebrates in streams. These reports will be used as the basis for a workshop being planned for March to explore realistic strategies and benefits for biological monitor- ing. A cluster analysis workshop was held at ERL-C to analyze and interpret data from four Phase I regions (1, 2, 3b, and 4). The cluster analyses were successful in separating regional populations into specific lake types. Analyses were performed on weighted data, producing population estimates for each cluster. A draft summary of the workshop has been completed. Analysis of the Clearwater Lake data set is continuing. This lake has the longest record (14 years) in North America and has the advantage of being situated in an area (Sudbury) in which deposition has changed dramatically since monitoring began. The analyses show that, for this extreme case, all four of the statistical techniques applied showed trends in seasonal data for ANC and $04 within five years. An outline of the Data Quality Objectives Document has been completed. Work on the draft Data Analysis Plan has begun. Preliminary outlines for several chapters are complete. The final format for the plan is not yet complete. A draft report on suitability for the TIME project of U.S. sites with preexisting watershed and/or monitoring information is under review. Project Manager: Jesse Ford FTS 420-4643/4600 22 ------- Corvallis Environmental Research Laboratory Project Status Report -- Acid Rain Effects December 31, 1987 Title: Direct/Delayed Response of Watersheds (57.1) Objective(s): Predict the long-term response of watersheds and surface waters to acidic deposition; classify watershed system response as direct, delayed or capacity protected. The Agency and Congress require information concern- ing rate of acidification and its reversibility. It is not known whether aauatic resources will deteriorate if emissions are held constant or decreased or whether aquatic resources will improve. This work is necessary for informed decision making concerning the timing and necessity for additional emission controls. A three-tiered approach is employed to classify watersheds. Level I entails statistical analysis of watershed characteristics and water chemistry and evaluated watershed and regional input-output elemental budgets. Level II estimates single factor response times for watersheds emphasizing key properties (e.g., sulfate adsorption capacity, base satura- tion, and indices of soil-water contact). Level III used dynamic system models to integrate important processes and predicts changes in watershed properties and surface water chemistry. A soil survey is an important aspect of the approach in that it provides data for Level I, II, and III analyses. Output Status: QA Report on SE soil mapping (11/87). Completed. Activities: Continued statistical analysis of relationships among watershed soils and lake water chemistry in the Northeast. Continued analyses of sulfur input-output budgets in the Mid-Appalachia Region. Mapped 13 of 45 watersheds in Northeast of special interest (i.e., unexpectedly high sulfur retention). Mapped 5 of 36 watersheds in Mid-Appalachian region. Presented 18 posters at the annual meeting of the Soil Science Society of America in Atlanta in December. At the annual meeting of the American Geophjysical Union in December, Project Manager chaired a session on modeling efforts of acidic deposi- tion. Project Manager: M. Robbins Church FTS 420-4666/4600 23 ------- 24 ------- Corvallis Environmental Research Laboratory Project Status Report -- Acid Rain Effects December 31, 1987 Title: Episodic Response Project. (58) Objective(s): Determine the magnitude, duration, and frequency of episodic chemical changes that accompany hydrologic events (both snowmelt and rainstorms) in streams of the U.S. Determine whether episodic chemical changes in streams have long-term impacts on fish populations. Improve regional estimates of the effects of acidic deposition on fish populations through consideration of episodic chemical changes. Estimate the number and proportion of surface waters in specific regions that are likely to experience biologically relevant acidic episodes. Output Status: Draft research plan for the Episodic Response Project (10/87). Completed. Peer-reviewed research plan for the Episodic Response Project (02/88). On schedule. Activities: Development of project data quality objectives, sampling methods, quality assurance protocols, and the research plan proceeded on schedule. A major activity during this period was finalizing the design of the biological research component of the Episodic Response Project (ERP) that will be funded jointly with the Biologically Relevant Chemistry Project. Fish transplant experiments will be carried out in streams in each of three regions of the eastern U.S; fish migration and mortality in response to acidic episodes will be measured in 4-6 stream reaches in each region, in addition to intensive chemical monitoring and field bioassays of toxicity. Chemical monitoring is scheduled to begin in spring, 1988 with biological studies beginning in summer 1988. A peer review workshop was held in November to evaluate the technical merits of the proposed approach to conducting regional-level research on episodic acidification. Seven peer reviewers were unanimous in their support of the project objectives and its contribution to understanding and quantifying the aauatic effects of acid deposition, but recommended that the extensive survey components of the ERP not be carried out at least until results from the intensive research are able to establish a linkage between chemical and biological impacts. Research proposals have been received from groups in three regions of the eastern U.S.: (1) the northern Appalachian Plateau in Pennsylvania, (2) the Adirondacks in New York, and (3) the Catskills/Poconos in New York. 25 ------- -'hese regions were previously identified as high priority for episodic research based on preliminary regional analyses using empirical models and National Surface Water Survey data bases. Evaluation of proposals for their technical merit and for their likelihood of meeting the overall ERP objectives has begun. Wet and dry deposition monitoring stations have been installed at the Fernow Experimental Forest by EPA in accordance with NADP/NTN protocols. USGS minimonitors for continuous measurements of pH, conductivity, and temperature were installed at weirs on both manipulated and control catchments during December. Two automatic water samplers were also installed at the same time. Both will be programmed to sample during stormflow events, triggered by an increase in stage. Watershed soil maps have been completed by the West Virginia Soil Conservation Service using protocols developed by the Direct/Delayed Response Project. Draft imple- mentation and Quality assurance plans have been completed and are in revision. Stream and soil sampling will begin after review and approval of these plans. Monitoring is expected to begin in January 1988. Findings: Application of simple models of episodic acidification showed that the Adirondacks are the highest priority region of study in the northeast; the northern Appalachian Plateau and the Catskills/Poconos are the highest priority regions in the mid-Atlantic. Results have confirmed that simple empirical models are a useful tool in quantifying the regional importance of acidic episodes in lakes and streams. Statistically-significant relationships between pH, ANC, Ca^"1", and Al vs. mean daily stream dis- charge were found for five streams in the eastern U.S. Publications: Eshleman, K. N., and P. R.

Eshleman FTS 420-4666/4600 26 ------- Corvallis Environmental Research Laboratory Project Status Reoort -- Acid Rain Effects December 31, 1987 Title: Synthesis and Integration of Aquatic Effects Research (59) Objective(s): Provide comprehensive and integrated interpretation of information germane to understanding the current and future effects of acidic deposition on surface waters. Output Status: Report on preliminary findings -- Regional Case Studies Project (to OADEMQA) (03/88). On schedule. Activities: Prepared and edited several water chemistry data bases for the Upper Midwest region for use in the Regional Case Studies (RCS) Project. Established and maintained a computer bibliographic system (Reference Manager) for use in preparing the reference section of the Regional Case Studies book. Held meeting of RCS participants to discuss and plan synthesis and integration for the RCS book. Initiated funding process with four RCS participants. Reviewed precipitation data from Rudy Husar for all ESL and WSL lakes. Prepared map showing location of all RCS regions. Drafted white papers on important RCS issues: ion ratio, definition of ANC and alkalinity, enrichment factor analysis, and calculation of organic acid concentrations. Initiated efforts with Dr. Jenne, Battelle Pacific Northwest Laboratories, to provide the capability of evaluating additional deposition scenarios via the DDRP models, ILWAS, MAGIC, and EOT. Continued development of the chapter outlines and planning for the 1990 Aquatic Effects Research Program Report. Met with PNL staff to plan the efforts to address regional dose-response relationships (Target Loadings) and quantification of recovery rates for acidified systems. 27 ------- Discussed proposed effort to develop regional estimates of future surface water status based on ELS data and MAGIC with University of Virginia staff. Effort would follow methods developed and applied to the Norwegian lake survey data. Findings: Data analysis is ongoing. First drafts of book chapters are due March 1988. Project Manager: Donald F. Charles FTS 420-4329 28 ------- Corvallis Environmental Research Laboratory Project Status Report -- Acid Rain Effects December 31, 1987 Title: Synthesis and Integration of Air Pollution Research on the Forest Response Program (63) Objective(s): Provide leadership and scientific support in the large scale synthesis and integration of forest research activities by quantifying the effects of acid rain on the health and productivity of forests. Output Status: Report on evaluation of new dendrochronological methods (10/87). Com- pleted. Report on evaluation of tree ring studies on two groups of red spruce (10/87). Completed. Report on evaluation of Pennsylvania gradient study (09/87). Delayed to 01/88; scope of work was increased. Report on framework for the role of stand dynamics in estimating pollution effects (07/87). Delayed to 01/88; scope of work was increased. Report on initial results from the FIBER matrix model (10/87). Completed. Report on feasibility study on 07/88 yield projections in TRIM-compatible format (09/87). Completed. Report evaluating tree-ring studies on low elevation red spruce (01/88). On schedule.

Annual report for the Synthesis and Integration Project (04/88). On schedule. Report on analysis of growth trends in southern pine plantations (06/88). On schedule. Activities: A decision on a Long-Term Monitoring Program will be made after January 1988. In preparation, the Synthesis and Integration staff will produce four reports by January on decision-making and planning a Long-Term Monitoring Program for forests. Drafts of those reports have been completed. 29 ------- Staff met with principal investigators from the Forest Response Program Research Cooperatives to discuss S&I data needs for the FRP Seedling Report due in early 1988. Summary data were subsequently received as requested. A briefing was given to the FRP Federal Management Group on seedling/ branch/tree integration and modeling activities within the program. Staff participated in a review of the EPRI Responses of Plants to Inte- grated Stress (ROPIS) Program. Project Manager: A. Ross Kiester FTS 420-4636/4600 30 ------- Corvallis Environmental Research Laboratory Project Status Report -- Acid Rain Effects December 31, 1987 Title: Quality Assurance (QA) Forest Response Project (64) Objective(s): Assure that data produced within the Forest Response Program (FRP), examining the effects of acid deposition on forests, are of known and documented quality. The data will be used for integration of research results to answer a series of policy Questions established by EPA's Office of Air and Radiation. Output Status: Annual report to Program Management (02/88). On schedule. Revised data quality objectives document (06/88). On schedule. Activities: The QA staff continues its routine auditing procedures within the FRP (82 completed to date). Audit protocols have been established at the national level to provide consistency across the Forest Response Project. National documentation has been revised to reflect growing experience in quality assurance procedures. This documentation includes revised QA Methods Manuals and the revised QA Implementation Plan. The QA staff also continues to meet the many reporting requirements of the quality assurance project. Results of Forest Response Program comparability studies for soil and foliar/sample tissue nutrient analyses are coming in and will be analyzed this quarter. The exposure eouipment performance evaluation audits will conducted in FY88 by the FRP QA staff; 13 audits completed in 1987, several of which detected some problems with equipment. Work continues on the four QA initiatives: wet vs. dry soil analyses; error sources in tree diameter measurements; testing cuticular wax data quality objectives (DQOs); and testing the effects of pesticides on physiological measurements. Results of the first two will be presented at the FRP annual meeting. The QA staff is implementing a QA tracking for project measurement vari- ables and techniques. Information will be used to organize sample exchanges, audits and audit samples, and comparability studies. The information ultimately goes into the FRP national data base. 31 ------- Findings: FRP audits continue to show high levels of scientific Quality, good documentation of results, and improving cooperation between similar projects. The continuing testing of methods of DQOs indicate that some revision is necessary, which we are carrying out. Initial results of soil sample exchange (interlaboratory comparisons) show some significant differ- ences between participating laboratories. These differences seem to be related most directly to variability in procedures and the error component used in the comparison. We will continue our initial analyses and testing of these differences. Project Manager: Jack Winjum FTS 420-4324/4600 32 ------- Corvallis Environmental Research Laboratory Project Status Report -- Acid Rain Effects December 31, 1987 Title: Effects of Atmospheric Deposition on the Condition of Forests in the Western U.S. (65) Objective(s): Evaluate the current and future responses of western coniferous forests to atmospheric deposition. The Western Conifers Research Cooperative efforts toward this goal are part of the national Forest Response Program. Output Status: Report on development of passive ozone monitor: delivery of prototype (12/87). Completed. Annual Report for the Western Conifers Cooperative (04/88). On schedule. Activities: Workshop, "Response of Trees to Air Pollution: The Role of Branch Studies" was conducted. An interagency agreement funding package with the Department of Energy (Lawrence Livermore National Laboratory: Comparison of the Response of Mature Branches and Seedlings of Pinus ponderosa to Atmospheric Pollution) was transmitted to Headquarters. Project Manager: Richard K. Olson FTS 420-4355/4600 33 ------- 34 ------- Corvallis Environmental Research Laboratory Project Status Report -- Acid Rain Effects December 31, 1987 Title: Effects of Atmospheric Deposition on Spruce-Fir Forests (66) Objective(s): Determine the effects of acidic deposition and associated air pollutants on spruce-fir forests. Includes investigations of the current reports of spruce decline at high elevations and investigations of potential mechan- isms of pollutant effect. Output Status: Annual Report for the Spruce-Fir Research Cooperative (04/88). On schedule. Activities: Conducted a symposium for American and German scientists to explore the state of knowledge regarding spruce-fir forests and to identify coopera- tive German/U.S. projects. Project Manager: Roger L. Blair FTS 420-4662/4600 35 ------- 36 ------- Corvallis Environmental Research Laboratory Project Status Report -- Acid Rain Effects December 31, 1987 Title: Effects of Acid Deposition on Southern Commercial Forests (67) Objective(s): Determine the effects of acidic deposition and associated air pollutants on southern commercial forests. Includes investigations of the current reports of growth decline in several southern pines and investigations of potential mechanisms of pollutant effect. Output Status: Annual report for the Southern Commercial Forest Research Cooperative (04/88). On schedule. Report on climate, soils, forest distribution, and air quality data for the southern U.S. (05/88). On schedule. Activities: Conducted a meeting of all cooperative principal investigators to discuss future research needs. Pis reported on individual projects. Met with investigtors from the field sites to resolve statistical issues. Project Manager: Roger L. Blair FTS 420-4662/4600 37 ------- 38 ------- Corvallis Environmental Research Laboratory Project Status Report -- Pesticides December 31, 1987 Title: Bioassay Development and GEM Studies (36) Objective(s): Develop rationale and procedures for evaluating survival, reproduction, potential for genetic exchange, fate, effects, and risks associated with release of genetically engineered biological control agents. Output Status: Journal article on aerial dispersal and epiphytic survival of Pseudomonas sringae during a pre-test for the release of genetically engineered strains into the environment (10/87). Complete. Activities: R.Seidler (CERL) and S. Hern (Las Vegas) gave presentations to Headquarters program office personnel on "The Release of Ice Minus Recombinant Bacteria at California Test Sites," summarizing ORD experiences with the on-site evaluation of the releases. They discussed quantitative evaluations of bacterial detection and aerosol movement during the spray releases. R. Seidler presented a seminar on "Release of Recombinant Bacteria into Microcosms and the Field," at New York Unviersity in November. Cooperative agreement research proposals were funded: "Novel Methods for Tracking Agrobacterium radipbacter K84 and Plasmid-Borne Genes in Agricultural Ecosystems" (Moore, Oregon State University). "Survival and Genetic Stability of Genetically Engineered Baculo- viruses" (Wood, Boyce Thompson Institute for Plant Research). This project will establish a predictive model for the survival capacity, genetic stability, and potential for gene transfer for genetically engineered baculoviruses. "Development of Methodology to Evaluate the Effects of Microbial Pesticides on Mycorrhizal Symbioses" (Linderman, USDA-ARS, Horticul- tural Crops Research Laboratory, Corvallis, Oregon). This project will develop methods to evaluate the impact of natural and genetic- ally engineered microbial pesticides on mycorrhizae. A preliminary particle dispersion model is being prepared to estimate bacterial concentrations downwind from a source area, and to compare with field observations. 39 ------- Findings: We continue to acquire and develop methods to study fate and survival of recombinant fungi in microcosms. A simple method has been used to extract DMA from four Basidiomycete fungi (Schizophyllum, Coprinus, Laccaria, and Hebeloma). This DMA has been digested with restriction enzymes and probed with the cloned rRNA genes from Coprinus (courtesy of P. Pukkila) to determine the usefulness of the method as a tool for distinguishing the four fungi. The patterns are different. We plan to continue these studies with several strains of the mycorrhizal fungus Laccaria collected from different geographical regions. We are also developing methods to transform Laccaria with a cloned Hygromycin B gene (courtesy of 0. Yoder) so the organism can be grown on a selective medium and also be unambigu- ously identified using the Hygromycin B gene as a probe. J. Armstrong and R. Rygiewicz are collaborating on research using already developed molecular biological methods for Aspergillus and Schizophyllum. They are transforming these strains with vectors being used for genetic engineering of fungi and developing methods to study the transformation of the mycorrhizal fungus Laccaria laccata. The availability of these methods will permit us to study the fate, stability, survival, and effects of recombinant fungi as they are developed by industry for environmental release.

Output Status: None this reporting period. Activities: In near-field studies on the CERL Wildlife Toxicology ponds, the red- winged blackbird is being evaluated as a candidate for evaluation of chemical effects on passerines in the field. These birds are vigorous, apparently quite sensitive to most chemicals, and appear to be a good candidate for nest-box, nest abandonment, and other behavioral studies in the field. Studies with this species will continue early in the spring 1988. Field studies using telemetry are in final planning stages for a spring 1988 evaluation of the effects of an OP on bobwhite nesting and foraging. A significant component of the doppler receiver system would not be ready for another year, so we have decided to use other (standard) transmitters. The study will, however, still use sophisticated tracking and computer graphics techniques to determine the movements of nesting adult hens during the foraging periods to determine the effects of OP on this phase of reproduction. Potential field protocols using nest boxes for passerines are being evaluated in a field situation. Data analysis and evaluation of Phase I is in progress. The effects of chemicals on nest attentiveness in valley quail and charac- terization of the habitat, nest sites, and "baseline" chemical residues are being conducted at a test site on the Wilson Refuge in Corvallis. These data will be utilized to provide exposure information for extraopla- tion to field environments. Findings: Preliminary nesting studies using local population of red-winged black- birds suggest that this species might be a good candidate for nest-box, nest abandonment, and other behavioral studies in the field. 41 ------- The early phases of the bobwhite telemetry study indicate that the test area is relatively clean of prior pesticide use and should provide the necessary habitat for these studies. Laboratory studies have demonstrated dose-response characteristics of an organophosphate which is repeatable. Preliminary results indicate that each chemical (or class of chemical) may have a repeatable characteristic temporal "profile" of action. Project Manager: Bill A. Williams FTS 420-4679 42 ------- Corvallis Environmental Research Laboratory Project Status Report -- Pesticides December 31, 1987 Title: Methods Development and Effects Measurement (38) Objective(s): Develop guidelines and test methods for evaluation of the effects of microbiological pest control agents (MPCAs) in non-target beneficial terrestrial species. Output Status: Report on laboratory testing and evaluation of selected MPCAs on nontarget birds (terrestrial) (02/88). On schedule. Activities: An experiment to evaluate the interim protocol for exposing bobwhites to a viral MPCA by intravenous inoculation using Autographa caliform'ca NPV a the test pathogen is nearly completed; tissue sample assays are complete. A literature search has been completed and a report is being written on questions, approaches, and methodologies that need to be addressed to validate interim protocols for respiratory exposure of avian species to MPCAs. The report will be finished in January and work will start soon thereafter. Protocol testing of the predatory neuropteran, Chrysoperua carnea, against the fungal MPCA, Beauveria bassiana, is proceeding.

Project Manager: Ramon J. Seidler FTS 420-4661 43 ------- 44 ------- Corvallis Environmental Research Laboratory Project Status Report -- Pesticides December 31, 1987 Title: Risk Methodologies for Wildlife Populations (40) Objective(s): Develop environmental risk assessment methodology using modified existing or newly developed fate, transport, and effects models to express risk as a probability statement with estimates of associated uncertainty. Output Status: Report on preliminary models to predict consequences of animal body burden of xenobiotics (10/87). Completed. Progress report on significant sublethal physiological and behavioral endpoints of populations affected by chemicals (10/87). Completed. Report on terrestrial population models for risk assessment: a state of the art review (02/88). On schedule. Report on terrestrial community models for ecological risk assessment: a state of the art review (02/88). On schedule. Activities: A literature review on available wildlife toxicology models is complete. New models are being developed and tested for wildlife populations. Evaluation of the relative importance of inhalation, dermal, and dietary uptake routes in avians is proceeding at Battelle Northwest Laboratories. Work continues at Montana State University to build a (animal) terrestrial toxicology database using dBASE III incorporating the original TERRE-TOX database. Findings: Toxicity tests based on short vs. long (96 hours or more) periods have been evaluated, and are not directly comparable; the timescale of toxic impacts varies from chemical to chemical. A simple means of scaling and extrapolating experimental data to asymptotic (long-term) endpoints has been developed so that data from different protocols can be compared, and a standard toxicity measure defined. Examination of the PHYTOTOX database has shown that laboratory-to-field extrapolation of toxicity in plants may be quite straightforward; the LC50 does vary, generally by less than two-fold. However, between species differences, even for taxonomically related species, are often enormous. This accentuates the need to find methods for interspecies extrapolation. 45 ------- Review of the existing literature suggested that little information is currently available in support of modeling efforts for terrestrial wildlife populations. Additional modeling approaches are being considered, Review of the existing literature revealed that little information is available about the importance of routes of exposure for terrestrial wlidlife. Tests continue to provide information about the relative importance of inhalation as a route of exposure in birds. Publications: Shirazi, M., and L. Lowrie.

Williams FTS 420-4679 46 ------- Corvallis Environmental Research Laboratory Project Status Report -- Toxic Substances December 31, 1987 Title: Terrestrial Toxicology (30.1) Objective(s): Evaluate, improve, and validate bioassay methods to assess the effects of toxic chemicals on plants and animals. Output Status: Report evaluating existing mathematical models of atmospheric deposition and exchange (02/88). Completed (10/87). Journal article concerning species differences in uptake and translocation of organic chemicals (01/88). On schedule. Journal article describing the degree of variation in plant responses to chemical insult when subjected to water stress (02/88). On schedule. Activities: The metabolism of different classes of industrial waste compounds by plants continues, directed by J. Fletcher, at CERL on a cooperative agreement with University of Oklahoma. Plant uptake studies are in progress to determine how the concentration of a pollutant'influences the movement of a chemical into and through a plant. The importance of species differences to these processes is being examined. A number of the species being examined are woody perennials. This is the first time any attempt has been made to study the root uptake of industrial waste compounds by woody perennials that are recommended by EPA for use in the revegetation of toxic waste sites. The root uptake model is being modifed to operate more efficiently. These modifications will facilitate its use in the general framework of the risk assessment under under development by EPA. The root model is being subjected to sensitivity analysis and steps are being taken to link the root uptake model with a soils model. The influence of water stress on plant response to chemical insult contin- ues to be examined. Findings: Cultured plant cells have been shown to metabolize environmentally stable 2,2',4,4'-PCB at a rate of 4.6 pmoles/n/g dry wt. Considering the large biomass and spatial distribution of plants, the metabolism of PCBs by plants could be formidable in certain environmental settings. 47 ------- Data collected on the uptake, biotransformation, and volatilization of l^C-nitrobenzene by seven plant species are being analyzed. Preliminary evaluation of these data indicate that in all cases a substantial amount of nitrobenzene taken up by the different species was volatilized into the atmosphere from leaf surfaces. The 146 recovered from the plants was primarily in the roots and most of this had been converted from the nonpolar parent compound to polar metabolites and insoluble constituents. Simultaneous exposure of plants to water stress and sublethal doses of a herbicide indicate that the combination of these stresses has a detri- mental influence on flowering which is not brought on by either stress condition separately.

Report Toxic Substances December 31, 1987 Title: Terrestrial Toxicology (30.2) Objective(s) : Improve and validate methods to assess the effects of toxic chemicals on plant, avian, and mammalian species. Output Status: Report on the effects of chemical on egg shell parameters in avians (10/88). On schedule. Journal article on the mechanism of transfer of chemicals to eggs and offspring in avians (10/88). On schedule. Activities: A journal article summarizing the investigations of uptake and distribu- tion of HCB in bobwhite egg and embryos is in preparation. Research on the effects of dicofol , an organochloride, on egg quality in mallards is proceeding on schedule. Data from the study will be used to evaluate the impact of a DDE-like compound on egg shell quality. Studies on the impact of nutritional status on the ability to detect chemicals in feed are continuing. A technique has been developed to precisely measure and record food consumption in birds. A technique to evaluate the relative toxicity of an analogous alcohol series (methanol to pentanol) is being tested. Preliminary tests have been conducted to determine appropriate routes, volumes, and timing of alcohol toxicity tests. These data are being generated for potential use in Quantitative Structure Activity Relationship techniques. Findings: Detection of dicofol in the gas chromatograph is difficult due to the breakdown of parent chemical into several other forms. Standard GC method- ologies are being utilized for this chemical and additional methods are being evaluated. Early results indicate that the toxicity alcohols may be related to the carbon chain length (e.g., each alcohol in the series has an additional carbon), Further work is needed, however, to relate these results to QSAR principles. 49 ------- Publications: Bennett, R.

Output Status: Journal article on DNA probe method for the detection of specific micro- organisms in the soil bacterial community (12/87). Complete. Activities: Presented an invited seminar at Rutgers University entitled, "Assessing the Risks of Environmental Releases of Recombinant Microbes Through Research" (R. Seidler). Presented the keynote address at the 1987 Conference of Biotechnology for the Preservation of Environmental Quality in Montreal in October.

They will be tested in microcosm systems for their competitiveness with wild type strains and their ability to decrease 2,4-D in the soil environment will be determined. Findings: We continue to study survival of Entobacter cloacae (pBR322) on the leaves of bean plants and in soil contained in large microcosm chambers. Environ- mental sensors hourly monitor the relative humidity, air temperature, leaf wetness, soil temperature, and soil moisture. Plants and soil are sampled for up to 21 days, processed, and plated on a selective medium. To determine replication with these chambers, we repeated the experimental design three times under the same chamber environments. The survival curve for bacteria in soil and on leaves compared well across experiments. Approximately 99% of the bacteria sprayed in the microcosm could not be recovered after 5 days. From day 5 to day 21, there was almost no further decrease in the bacterial populations. The survival curves from these experiments are being analyzed by a statistician to identify the sources of variance within the experimental design. In two additional experi- ments, a humidifier was programmed to increase the relative humidity of one chamber to 95% during the 6-hour night period, while the second chamber was kept at 40 to 50% relative humidity. The higher relative humidity increased the soil moisture in that chamber. In these experi- ments, the £. cloacae (pBR322) on leaves showed similar death curves in both low and high humidity environments. However, these bacteria survived better in the soil with a higher moisture content as compared to those in the drier soil . Publications: Holben, W. E., J. H. Jansson, B. K. Chelm, and and J. M.

Output Status: None scheduled this reporting period. Activities: Development of immune function tests for mallards and bobwhite continue. A collaborative effort with staff from the Oregon State University College of Veterinary Medicine to define avian serum chemistry profiles continues. Baseline data for blood chemistry of mallards and bobwhite has been completed. A Tb test for avians has been successfully tested. Work is progressing on standardizing the lymphocyte migration and carbon clearance assays. An in vitro macrophage colony has been developed for use in immunologic screening tests for mallards. This colony is needed to support future immunologic function tests for avians. Experiments using the colony are planned for early spring. Lymphocyte migration tests are currently under development and evaluation. Although several aspects of this test are still incomplete, considerable progress has been made. Gamma glutamyl transpeptidase (gGT), alkaline phosphatase (ALP), lactate dehydrogenase (LD-L), aspartate aminotransferase (AST), alanine amino- transferase (ALT), amylase, albumin/globulin ratio (A/G), glucose, and cholinesterase (ACHE) tests are routinely conducted by the wildlife team. These screening panels are being evaluated in bobwhite and mallard. Project Manager: Bill A.

Completed. Journal article on chemicals and mycorrhizae on root permeability and cation fluxes (12/87). Delayed; additional data being added. Activities: The information and discussions synthesized from interviews, workshops, and literature evaluations on critical systems has been analyzed and summarized in a report submitted to EPA. The microcomputer version of PHYTOTOX, along with the newly completed User's Manual, has been distributed to selected parties in EPA for testing. Additional mycorrhizal studies are being conducted to confirm some prelim- inary results which were not consistent with currently held views on this topic. Findings: The draft report on "Effects of Chemicals on Soil Biota" indicates that there are numerous contradictions on this topic in the published litera- ture. The microcomputer version of PHYTOTOX has greatly expanded the number of persons who can now gain access to it, and therefore it is being effec- tively used for the first time to resolve questions on a day-to-day basis. 57 ------- A final analysis of data from the mycorrhizae study showed plant species differences which were not anticipated. Additional experiments have been initiated to evaluate these findings. Project Manager: Bill A. Williams FTS 420-4679 58 ------- Corvallis Environmental Research Laboratory Project Status Report Toxic Substances December 31, 1987 Title: Validated Hazard Assessment Using Microcosms and Field Sites (42) Objective(s): Determine the ability of toxicological testing methods to predict an effect on field populations. Output Status: Journal article on a continuous-flow method for measuring the effect of chemicals on soil nitrification (12/87). Completed. Journal article on the effects of selected chemicals on microbial popula- tions (01/88). On schedule. Activities: An investigation is underway to evaluate the effects of body size and age on sensitivity to chemicals in avian dietary tests. This study will provide an evaluation of the impact of age and size on the results of 1059 protocols for bobwhite quail. A computerized metabolic and respiratory system has been tested which measures oxygen consumption and C02 production simultaneously in up to five birds or small mammals,, All computer software for test control and data recording is complete. This system will be used to evaluate meta- bolic and thermoregulatory measurements in conjunction with toxicity tests. Work is continuing on the development of an automated system to measure respiration in soil culture. This will be used to measure the effect of toxic chemicals on random metabolism of soil populations over small increments of time where responses are often missed in traditional culture techniques. The continuous-flow culture procedure 1s being modified to evaluate the effect of chemicals on soil nitrification. Project Manager: Bill A.

The two chemicals, though related as chlorinated pesticides, have different solubilities, sorption rates in sediment, and different toxicity as related to percent organic content of spiked sediment. Project Manager: Alan V. Nebeker FTS 420-4875 61 ------- 62 ------- Corvallis Environmental Research Laboratory Project Status Report Water Quality December 31, 1987 Title: Lake Restoration (13) Objective(s): Provide EPA's Office of Water with a comprehensive Lake Restoration Guidance Manual (LRGM) that incorporates all aspects of lake management and restoration including types of techniques, cost-effectiveness, regional prioritization of projects, and an assessment of efficiency of treatment techniques. Work will include technical assistance to States and Regions concerning application of the LRGM to the Clean Lakes Imple- mentation Program conducted at the Region/State level. Output Status: Lake Restoration Guidance Manual (04/88). On schedule. Activities: The final draft of the LRGM has been delivered to authors for comment following incorporation of reviewer and workshop participant comments received at the annual North American Lake Management Society conference in November. The project leader, two authors, and the NALMS editor met in December to finalize the document. It appears the LRGM will be delivered ahead of schedule. The scope of this project was amended at the request of EPA's Office of Water to include plans for technical assistance to the Regions and States. This assistance includes development of workshop brochures and materials based on the LRGM, the conduct of workshops in three locations, the critical analysis and documentation of the suitability of current Clean Lakes data bases to assess longevity of various lake treatment techniques, and the development of a long-term monitoring plan to assess success and longevity of effectiveness of future Clean Lakes projects. Project Manager: James C. McCarty FTS 420-4601 63 ------- 64 ------- Corvallis Environmental Research Laboratory Project Status Report Water Quality December 31, 1987 Title: Wetlands Research on Mitigation and Cumulative Effects of Loss (14) Objective(s): Implement research on cumulative impact assessment and mitigation to: (1) assess the effects of cumulative wetland losses on wetland functions in the landscape; (2) improve methods of creating, restoring and enhancing wetlands and wetland functions; (3) provide guidance for the design of effective mitigation projects; and (4) provide information through the publication of "Community Profiles" and other wetlands information. Output Status: Report on conceptual framework for cumulative impact assessment (12/87). Completed. Report of National Wetland Symposium: Mitigation of Impacts and Losses (11/87). Completed. Production of the Proceedings from the National Wetland Technical Council's symposium on prairie wetlands (02/88). On schedule. Provisional guidance document based on literature synthesis (06/88). On schedule. Report on mitigation projects in EPA Regions IX and X (09/88). On schedule. Activities: The program was peer reviewed and evaluated for progress and FY88 operat- ing plans. The panel was generally supportive and suggested improvements that will be adopted. Final quality assurance checks were made of the data bases of 404 permits of freshwater mitigation projects in Louisiana and Mississippi, and of projects in Alabama and Washington; initiated trends analysis of these data bases and continued that for the Oregon data base; continued program- ming the data management system to increase user friendliness and to compile information for analysis. Data entry programs for the Oregon field study are completed; data entry and concurrent quality assurance checks are progressing; completed analysis of water samples for heavy metals, QA/QC checks confirm that quality standards were met; site selection continues for pilot study in Florida to test methdos for evaluating created and restored freshwater emergent wetlands and adapting the method to forested wetlands; a draft proposal for a similar study in New England was reviewed, this study will 65 ------- be done in cooperation with Region I; revision of the documentation of a method for evaluating created and restored freshwater emergent wetlands and the supporting quality assurance protocol continues. Review of the manuscripts for the Literature Synthesis has been completed and editorial review is in progress; the draft Overview and Research Needs was received from representatives of the National Wetland Technical Council and circulated for comment. Findings: Preliminary analysis of the 404 permit data bases have identified some regional patterns in permitting. For Oregon and Washington, only permits that required compensation in the form of creation or restoration were examined. In Oregon, impacts on 11 wetland types were permitted; four types comprise 77% of the number of wetlands impacted. In Washington, impacts on 23 wetland types have been permitted; four types comprise 69% of the number of wetlands impacted. When all the permits issued involving freshwater wetlands in Louisiana, Mississippi, and Arkansas were examined, a different pattern emerged. Twelve wetland types were impacted; 81% of the number of wetlands impacted were of one type, palustrine forested wetlands (bottomland hardwoods). The data base from Louisiana, Mississippi, and Alabama shows that over half of the permits issued did not require compensation in the form of wetland creation and restoration. The area of wetlands impacted was 30,095 acres, while requirments for creation or restoration to compensate for losses was 3,481 acres. A workshop sponsored by the Wetlands Research Program to develop a frame- work for cumulative impacts research discussed the prospects for develop- ing methods to assess the potential cumulative impacts of wetland loss on the major functions of systems of wetlands and proposed a research strategy. The primary conclusion to be drawn from the papers and the workshop is that a sound scientific basis for regulation will not result from acquiring more information on more variables. It will come from recognition that a shift to larger temporal, spatial, and organizational scales is needed. The workshop proceedings proposes alternative approaches. Participants agreed that cumulative impacts could not be managed effectively when Section 404 permit applications continue to evaluated on a case-by-case basis without reference to their landscape context.

Presented paper on attainable lake trophic state at North American Lake Management Society meeting. Chaired and presented paper on use of ecoregions to develop biocriteria at national biocriteria workshop. Findings: Developed and tested in the Midwest, the IBI was adapted for use in western Oregon, northeastern Colorado, New England, Appalachia, and northern California. The concept was extended to Louisiana estuaries. 67 ------- Because of low species richness, IBI metrics were replaced, deleted, or added. Modifications followed the original IBI concept and its theoret- ical underpinnings. The IBI holds promise for direct biological monitor- ing, and several states have incorporated it in their monitoring and standards programs. The IBI thus serves as a quantitative biological goal for water resource management (Miller et al.). A map of summer total phosphorus in lakes was compiled for the Upper Midwest to clarify regional patterns in attainable lake trophic state. The maps were compiled using patterns of total phosphorus data and associ- ations between these data and geographic characteristics, such as physio- graphy, land use, geology, and soil. Regions depicted on the map repre- sent areas of similarity in phosphorus concentrations in lakes. The map provides a framework for determining representative lake conditions and realistically attainable phosphorus levels within each region (Omernik et aK). ~~ Publications: Heiskary, S. A., C. B.

Output Status: Internal report on significant levels of chemicals found in bodies of water utilized by waterfowl and small mammals (11/88). On schedule. Internal report on pollutants considered to pose the greatest threat to wildlife when existing WQC are met (12/88). On schedule. Activities: Review of the WQC documents has begun. Several WQC pollutants identified have the potential to bioaccumulate in fish and other elements of the food chain. Research to identify chemicals with the greatest potential for accumulation in piscivorous birds and mammals is underway. A study to determine the effect of selenium on waterfowl in outdoor ponds has begun. This is a cooperative effort between investigators at the University of Wisconsin, Madison, the Duluth EPA laboratory, and the Wildlife Toxicology Research Group at Corvallis. Preliminary work has started to evaluate WQC pollutants which have the potential to bioaccumulate in food sources for birds and small mammals. In-house feeding tests planned to evaluate the toxic effects of polluants when water contains levels appropriate to those found when WQC are met. Findings: The toxic, oncogenic, and teratogenic effects of high levels of selenium on waterfowl have been documented. The levels of selenium and the specific analogs necessary to produce these effects have not been well documented. Project Manager: Bill A.

Output Status: Journal article on UV-B effects on tree seedlings (09/88). On schedule. Report on indirect effects of UV-B radiation on a commercial fishery (10/88). On schedule. Report on selected UV-B effects on wetland rice (09/89). On schedule. Activities: The Director of Office of Air Quality Planning and Standards was briefed on the ERL-Corvallis' Stratospheric Ozone Project. Findings: Research supported by the Corvallis Laboratory resulted in a manuscript evaluating the possible risks and uncertainties concerning stratospheric ozone depletion and its impact on plants. The manuscript addresses (1) the risk to crop yield resulting from both direct and indirect effects of enhanced solar UV-B radiation, (2) the uncertainties associated with the effectiveness of UV-B radiation, and (3) recommendations for standardiza- tion of experimental procedures and future research priorities. The manuscript examines all of the published and unpublished material cur- rently available to assess the likely impact of projected increases in UV-B radiation upon global productivity and upon the distribution and abundance of plants in natural ecosystems. Despite a broad range of experimental protocols and dosimetry, in nearly half of the plant species examined, UV-B radiation produced a deleterious effect on yield. UV-B radiation affected both the quantity and quality of crop yield, but the magnitude of the effect was highly variable from one year to another. The limitations to this assessment are formidable, particularly due to a paucity of experimental data and the slow development of appropriate technology. Therefore, the actual impact on crop yield resulting from exposure to increased levels of UV-B radiation may be far greater or somewhat less than current knowledge indicates. 71 ------- Publications: Teramura, A.
