                        PREFACE

   The  Continuous  Air Monitoring  Program, commonly
known  as  CAMP,  represents  the  first large-scale  effort
to  obtain  comparable,  continuous,  concurrent  data  on
gaseous  air  pollutant  levels  in  the  atmospheres  of  a
number of major American  cities.   The fundamental pre-
mise  in  the  establishment  of  the program  was the need
for such  data to augment research on the  nature of air
pollution  and  its  impact on  man  and  his  environment.
Consequently,  the  Public  Health  Service  wishes  to  en-
courage  all  interested  research personnel to participate
in exploiting the many avenues of investigation opened by
this information.   To make  the  CAMP data  immediately
available  for  such use,  brief interim summaries  have
been prepared monthly since the inception of the program.
Sufficient information has now been accumulated to warrant
publishing a  series of  more  comprehensive  reports, of
which this volume  is  a  part.  A  similar publication sum-
marizing  the results of 1962-1963 operations in Cincinnati,
Ohio,  is  available,  and volumes are planned for data from
other   cities  and  subsequent years.   In addition  to this
series,  special reports discussing  in detail  specific as-
pects   and interpretations of  the  data will  be  prepared
periodically;  currently  in  progress  are  studies  of the
effects of sample  averaging time,  of the ratios of peak
to  average concentrations, and of pollutant interrelation-
ships.

   This  volume  presents  the results  of  operations in
Washington,  D.C.,  during 1962  and 1963.  It is intended
to  serve  not only as a  report on  CAMP operations, but
also as an introduction  to the subject  of gaseous air pol-
lution for the technical  reader unfamiliar with such work.
Following a  summary of the  background of CAMP and its
current operations,  Part 1 presents background  informa-
tion about the  Washington area  to  assist  the reader in
visualizing  the  interpretations of the  data in  the light of
factors  peculiar to Washington.   Part 2 contains  a brief
summary of  the data with  analysis and discussion, and
Part 3 summarizes the data  as hourly, daily, and monthly
mean  concentrations to permit the use of this volume as
a reference.  An appendix describes the instrumentation.

   In  addition to the series of publications,  copies of the
CAMP master  data files, maintained  on  magnetic tapes
for electronic computer analysis, can be  made  available
for use  by  anyone having access to computer facilities.
Since  data  from the  National  Air  Sampling Network of
the Public  Health  Service, as  well  as large  quantities of
mortality, morbidity,  meteorological,  and socioeconomic
data,  are  also  available on magnetic  tapes from various
sources, the  possibilities for computer  analysis are almost
limitless.  Correspondence concerning the availability or
use of  CAMP data should  be directed to the Chief, Air
Quality  Section,  Laboratory  of Engineering  and Physical
Sciences, Division  of  Air  Pollution,  Robert A. Taft Sani-
tary Engineering  Center,  4676  Columbia  Parkway, Cin-
cinnati, Ohio 45226.

                 ACKNOWLEDGMENT
   The Public Health Service acknowledges with apprecia-
tion  the many  contributions of the  several cooperating
local  agencies  to  the  operation  of  the Continuous  Air
Monitoring  Program.    In  the  publication of this volume
with data  from  Washington,   particular appreciation is
expressed  to the District of  Columbia Department of
Public   Health,  Air Pollution  Section,  for  the operation
of the station and for obtaining the station site.
                       ABSTRACT
   This report  presents the results of  the operation of
the Public Health Service Continuous Air Monitoring Pro-
gram (CAMP) in Washington, D.C., during 1962 and 1963.
Data  on atmospheric  levels of sulfur  dioxide, oxides of
nitrogen,  total  oxidants, total  hydrocarbons,  and carbon
monoxide  are summarized,  analyzed, and discussed.  The
data  are  tabulated  as hourly,  daily,  and monthly mean
concentrations;  background  information  about  Washington
and a description of the instrumentation used are included.
                           VII

-------
            THE  CONTINUOUS  AIR  MONITORING PROGRAM
   It has been estimated that as many as 6000
urban areas in the United States are affected to
some  degree by  air pollution,  but  air quality
measurements have been made in no more than
a  tenth  of  these communities.1   Generally,
measurements are limited to particulate  pol-
lution,  i.e. dusts  and soot in the air. Data on
particulate weight from dustfall collectors and
high-volume filter samplers are available most
frequently; measurements of particulate soiling
in  COH or  RUDS* units  are less commonly
made.

   In recent years, there have been significant
increases  in the technical ability and  legal
authority needed to control the discharge of par-
ticulates  to the air, and some urban  areas have
made gratifying progress in reducing such pol-
lution.   During this period, however, public
awareness  and  official concern has been  ex-
panded  to encompass the less obvious,  but more
complex, problems of gaseous pollutants.  Even
communities that  have  never been particularly
troubled by particulate pollution are showing in-
creased  evidence of photochemical  smog, a
serious  manifestation of gaseous pollution, in
periodic  episodes  of decreased visibility,  eye
irritation, and damage to vegetation.

   Available data  on gases  in the air, however,
have been even more limited in distribution  and
in quantity than  the sparse  particulate data.
The  National  Air  Sampling Network of  the
Public  Health Service has measured sulfur di-
oxide and  nitrogen dioxide in about 50  cities by
means of 24-hour integrated samples taken bi-
weekly.  The cost of more frequent sampling has
limited routine gas monitoring to only the largest
urban  areas.  In  some of  the smaller cities,
intensive studies of some gaseous pollutants have
been made by local agencies and  the Public
Health Service during cooperative air  pollution
surveys,2'3-4 but these  samp ling programs have
been conducted for relatively short  periods of
time.   The  rare  instances of  daily,  24-hour
sampling  programs that have been undertaken
have usually been restricted to the collection of
integrated samples of at least 2 hours duration,
despite the knowledge that the concentrations of
gaseous pollutants  can change significantly with-
in a  few minutes.
   Understanding of the significance of gaseous
pollution is handicapped not only by the scarcity
of data, but also by differences among several
methods  of sampling for any single  pollutant.
These differences have  limited  comparison
among, and joint interpretation of, the results
of numerous studies.   In  addition, concurrent
data for more than one pollutant at any one site
are almost completely lacking; this lack handi-
caps  studies of pollutant interrelationships and
the more complex effects of pollution.

   The need  for  continous concurrent data for
several gases, obtained by  comparable methods
in various  communities, was recognized some
years  ago.  It was also apparent, however, that
the requisite  sampling program would be far
more  difficult  than any  effort previously at-
tempted.  Completely satisfactory instrumen-
tation  was  lacking.   The subject itself — the
rapid and concurrent variation of atmospheric
pollutant levels — was little understood. Ques-
tions  of  which pollutants  could or should be
measured were largely unanswered.  Further-
more, few groups interested  in  air pollution
could  marshal the financial or manpower re-
sources needed for such an undertaking.

   In  1960, Congress provided impetus and fi-
nancial support for a program capable of resolv-
ing some of the problems of gaseous pollutants
and their sampling. Public Law 86-493 directed
the Public Health Service to accelerate research
into  the  effects  of air pollutants from motor
vehicles on human health.  Since such pollutants
are largely gases for which available data were
inadequate, the Continuous Air Monitoring Pro-
gram was established to  measure  the concen-
trations of various gases in the ambient atmos-
phere. Development of the necessary instrumen-
tation  was accomplished by the Public Health
Service through a contract with a commercial
instrumentation firm, and  the operation of the
program was assigned to the Air Quality Section
of the Laboratory of  Engineering and Phusical
Sciences  in the Division of Air Pollution.  The
first station was opened in  Cincinnati in October
1961,  and by early 1962 five additional stations
were operating.  During 1962 and 1963 these six
stations were located in Chicago, Cincinnati,
New Orleans,  Philadelphia, San Francisco, and
Washington, and  were operated by the Public
 *COH (Coefficient of Haze) units are based on the transmission of light through a soiled filter; RUDS (Reflectance Units of Dirt Shade),
 on the reflection of light from a soiled filter.  Both measure primarily the smaller particulates.

 Health  Service in cooperation with the local air
 pollution control agencies. The instruments  at
 the  New  Orleans  station were  subsequently
 moved  to  St. Louis in 1964, and the San Fran-
 cisco equipment to Denver in 1965. Comparable
 data are also obtained in Los Angeles and New
 York, at stations provided and operated by local
 groups.  Insofar as practicable, the stations are
 comparably  located.  They have been placed  in
 or near the  principal business district in each
 city, and situated wherever  possible to avoid the
 influence of  significant  point sources of pol-
 lution.

   The  primary  objective  in  establishing the
 Continuous Air Monitoring Program was to over-
 come at least partially the deficiencies in exist-
 ing data on  the  nature of air pollution by pro-
 viding  information  that was   heretofore  un-
 available,  i.e., continuous,  concurrent  data on
 several gaseous pollutants obtained comparably
 in a number of urban areas.   It is hoped that
 this  effort will stimulate further air pollution
 investigations and the control of pollution where
 required; hence the program for publication of
 the CAMP data has been planned to make this in-
 formation  available for use by those persons
 interested in any of the several areas of air
pollution research and control.

   Since a CAMP station constitutes only one
 sampling site in a given community, the data do
 not necessarily quantitate  air pollution levels
beyond  the immediate vicinity of the  station;
however, the  data do have application to studies
of the broad patterns of temporal variations and
pollutant interrelationships  that affect the entire
urban area.   The data  have  already demon-
strated  significant occurrences of photochemical
smog in communities  other than in California,
and further investigation of this phenomenon is
anticipated. The CAMP data are now being used
in conjunction with meteorological data in dy-
namic mathematical diffusion models; in studies
of the effect  of large, single  sources of pol-
lution on ambient  concentrations;  and in the
differentiation of temporal and geographic var-
iations.

   Delineation of the  effects of air pollution on
man and  his environment depends upon know-
ledge of  the  variability  of pollutant  concen-
trations  as well as of the  average levels.  In
the field, CAMP data  can be used in epidemi-
ological  studies of the health effects of various
pollutant combinations and of changing pollution
levels; in the laboratory, the data can be applied
to the selection of realistically varying pollutant
concentrations and combinations  for  the  ex-
posure of animals and plants.  Pollution effects
and behavior can also be examined in terms of
various  time-concentration  arrays.  CAMP data
thus provide some of the information needed to
evaluate proposed air quality  criteria and the
impact  of implementing such  criteria through
air conservation programs.
   The improvement and development of tech-
niques for  measuring  air  quality are also of
considerable importance. Relationships of peak
to average concentrations over various periods
of time are expected to provide guidance toward
optimum balance in the use of continuous or in-
tegrating types  of instruments, or both, in the
light of cost versus information gained.  Sim-
ilarly, studies  of pollutant interrelationships
may indicate that one pollutant, or a combination
of a few, can provide a good index  to the  be-
havior of others.  Either of these factors could
affect both the type and the cost of air quality
measurements.

                         PART 1:  WASHINGTON,  D.  C.
    This brief discussion of the Washington area
 is included to provide a basis for visualizing the
 interpretations of  the  data  in  Part  2 in the
 light of features peculiar to the Washington area,
 and to assist  in evaluating the  applicability of
 these interpretations to other locations.


 TOPOGRAPHY ANDLANDUSE

    The  city of Washington is co-extensive with
 the District of Columbia, which occupies an area
 of about 69 square  miles between Maryland and
 Virginia (see  Figure 1-1).  It is situated at the
 confluence of the Potomac and Anacostia Rivers,
 at the  upper  end  of the Potomac tidal basin.
 Washington lies on the relatively flat  Eastern
 coastal plain; elevations in the area range from
 10 to  400 feet above sea level. The only distinc-
 tive features of the  terrain are the bluffs border-
 ing the Potomac River as it enters the District
 from  the Northwest, and the Rock  Creek ravine
 running north and south through the middle of the
 District's northwest sector.
   The  characteristics of a major urban center
change with distance from the central city core.
The Standard  Metropolitan   Statistical  Area
(SMSA) of Washington* (Figure 1-1) includes the
District of  Columbia, the Maryland counties of
Montgomery and Prince Georges, the Virginia
counties of Arlington and Alexandria,  and the
independent  Virginia  cities  of Alexandria and
Falls Church,  with  a  total population over  2
million.  Much of the outlying area is rural and
very  sparsely  inhabited, however, making the
SMSA a poor index of the extent of urbanization,
and  hence a poor  basis for comparison with
other cities  (Table 1-1).  The Washington Ur-
banized  Area,* which includes only those in-
corporated places of at least 2500 persons and
adjacent unincorporated  census  tracts  of 1000
or more persons per square miles, is  also in-
dicated  in Figure 1-1; the Urbanized Area con-
tains  over 90 percent of the population on about
23 percent of the land, a density of 5300 persons
per square mile. The City of Washington itself
is the center of population; it is the ninth largest
city  in  the  country, with a population over
                                          TABLE 1-1

 760,000  and  a  population density exceeding
 55,000  per square  mile  in some  areas and
 averaging  more  than  12,000  per square mile
 (Figure 1-2).  Because the sampling station is
 located on  the  fringe  of  the  downtown  area,
 statistics for the City of Washington are  the
 most  appropriate index with  reference  to  air
 pollution as measured by CAMP.  Similarly, the
 comparative statistics  for other CAMP sites
 (and two other east  coast  cities) in Table 1-1
 are based on the central cities.

    Washington is essentially  an  institutional
 city,  with  most of the nonresidential land used
 for governmental purposes; a  1955 survey in-
 dicated that 42 percent of the land in the District
 of Columbia was owned by the Federal Govern-
 ment.  The only portions  of the area that are
 somewhat  industrialized  are  located  in  the
 Alexandria - South Arlington  area of Virginia
 and  in the  northeast sector of the District of
 Columbia.

    The relatively minor  role  of industry  in
 Washington is  also  evident in  Table 1-2,  a
 summary of employment; manufacturing activi-
 ties provide  only 4 percent of the total em-
ployment in Washington.  The Federal Govern-
ment,  on  the  other hand, employs the largest
segment of the work force.   In fact, all levels
of government,  Federal, state, and  local,  in-
cluding nearby military establishments, employ
some  40 percent of the working population in
administrative, scientific, and clerical occupa-
tions,  most of which do not involve the pro-
duction of air pollution.
PRINCIPAL SOURCES OF POLLUTION

   Because the minimal industrial activity in
the Washington area  is  generally restricted to
light  manufacturing,  process losses are neg-
ligible, and  the  vast majority  of  gaseous  air
pollution is produced by the combustion of fuels
for transportation, heating, and electric power
generation.  Combustion of gasoline and diesel
fuel  for transportation  is responsible for  the
largest portion of carbon  monoxide, oxides of
nitrogen, and hydrocarbon emissions.  The  use
of coal, fuel oil, and natural  gas  for space
heating and  electric  power generation contri-
butes most of the sulfur dioxide pollution and a

   Gaseous  pollution from motor vehicles is a
proportionally  greater problem  in Washington
than in most areas, largely because of a very
high density of vehicles and the minimal  in-
dustrial  contribution.   Although  the density of
private passenger cars in the Urbanized Area
(Table 1-1) is no greater than in some other
urban areas, the total motor vehicle density in
the city  proper is one of the highest among the
major  cities in the  country.  In  addition to the
2600 private passenger cars per square mile in
Table  1-1,  20,000 trucks and busses,  10,000
taxicabs, and  large  fleets of government and
military vehicles  raise the total  to a density of
over  4000  motor  vehicles per  square  mile.8
When automobiles owned in the suburbs, through
traffic on several major highways, and a large
number  of  tourists'  automobiles are  also  in-
cluded, the total rises to about 700,000 vehicles,
which daily consume 1,950,000 gallons of gaso-
line and over 48,000 gallons of diesel fuel in the
Washington  Standard  Metropolitan Statistical
Area (SMSA).  The vehicular density is concen-
trated  still  further in the  downtown core by a
massive  influx of  suburban commuters who
work  in downtown Washington;  traffic  survey
data indicate that  about half the vehicles in the
area  enter  and leave  the city daily,  and that
over  a third of them  concentrate in 1  square
mile of the downtown core.

    Most of the non-vehicular gaseous pollution
 results from the combustion of coal,  fuel oil,
 and natural gas for  space heating and electric
 power generation. Of the total  energy require-
 ment  in the Washington SMSA (other  than for
 transportation) 46 percent  is  produced  from
 coal, 24 percent  from fuel  oil, and 30 percent
 from natural gas.

    An estimated  3-1/2  million tons of coal are
 consumed  annually; 79 percent of this total is
 used by the local electric power utility, 12 per-
 cent by the Federal Government in large heating
 plants, and the remainder for residential space
 heating, industrial, commercial,  and  miscel-
 laneous uses.   About 26 percent of the total is
 consumed  in one large power plant in Alexandria,
 Virginia;  another 40 percent is  used in a power
 plant at Dickerson, Maryland, more than 30 miles
 from  Washington.  Most of the  remainder  is
 consumed  within the District of Columbia. About
 40 percent of the latter is used for space heating
 by the Federal Government; another 40 percent
 is  used by two of the electric power  utility's
 smaller plants. The remainder of the coal con-
 sumed in  the District is used  for small com-
 mercial and industrial boilers  and for heating
 apartment buildings.  The sulfur content of the
 coal used  in the area ranges  from 0.9  to 3.0
 percent, averaging about 1.5 percent.

   Approximately  360,000,000  gallons of fuel
 oil are used each year.  About two-thirds of the
 total is composed of distillate oils used pri-
 marily for residential heating; the other third, of
 residual oils used as heating fuels for govern-
 ment buildings, hotels, and apartments. Sulfur
 content averages  about  0.3  percent  in  the
 distillate  oils,  and about 2.8  percent in the
 residual oils.

   Natural gas  is the major  residential heating
 fuel; about 63  billion  cubic  feet of gas burned
 annually in the Washington  metropolitan area.

   Seven incinerators  and open-burning opera-
 tions at two large dumps in the metropolitan
 area dispose of about 2000  tons of dry refuse
 per day, or  about  two-thirds of the total in the
 SMSA.  (Wet garbage  is not incinerated, but is
used as livestock feed.)  Pollution  from these
disposal operations amounts to only a few per-
 cent of estimated total gaseous emissions, but
 most of the emissions and almost all of the com-
plaints are caused by the open-burning dumps,
which burn only about one-seventh  of the total
refuse.
    Locations of the major central heating plants,
 power stations, and incinerators in the metro-
 politan area are indicated in Figure 1-3.  The
 position of the CAMP station, located on the
 southeast  corner  of the intersection of First
 and L streets, N.W., is also shown.

 METEOROLOGY
    Pollutant concentrations in the atmosphere
 depend not only upon the amount of pollution
 emitted  from  sources in the community, but
 also  on the extent to which  the  pollution is
 diluted or  dispersed in the atmosphere.  In the
 Washington area, this dilution depends prima-
 rily  on  meteorology, since topographic influ-
 ences are minimal.

    The extent of dilution and  dispersion hori-
 zontally  is determined  primarily  by  surface
 wind speed.  Table 1-3 summarizes by season
 for several  years  the average  surface wind
 speeds*  in  Washington and the degree of hori-
 zontal dilution  afforded.  In addition, Table 1-3
 includes the frequency of winds affording "poor"
 horizontal  dilution, i.e., winds less than 7 mph.
 The average wind speeds indicate that the gross
 horizontal  dilution  in Washington is generally
 best in winter and spring and poorest in summer.
 In  all seasons  the  city experiences light winds
 affording  "poor* dilution a significant portion
 of  the  time; although much  of  this  time  is
 probably at night, when  wind  speeds are  typ-
 ically  lower, a few  occasions  of light winds
 throughout   an  entire  day did occur  in each
 season.

 west winds are predominant; in summer, south-
 erly winds  are predominant.  In all seasons,
 easterly winds are relatively infrequent.

    The extent of pollutant dispersion in a verti-
 cal direction  is determined by  the  stability of
 the atmosphere, i.e., the  degree of  turbulent
 mixing in the air mass.  This stability in turn
 depends on the temperature gradient in the low-
 est layer of the atmosphere. If the temperature
 decreases with altitude at  a rate greater than
 5.4° C per  1000 feet  (the  dry adiabatic  lapse
 rate), the atmosphere is unstable and turbulent
 mixing occurs.  If the temperature decrease is
 less than 5.4° C per 1000 feet, or if the tempera-
 ture increases with height, the atmosphere is
 stable and mixing is suppressed.

    During the  daytime,  lowest  layers of  the
 atmosphere   are typically  unstable,  the low-
 lying warm  air tends to rise, and the  resulting
 air movement  mixes gaseous pollutants verti-
 cally  throughout the air mass.  Under  these
 conditions, the  degree of vertical dilution af-
 forded is determined by the  depth of the layer in
 which mixing  can occur.  This mixing depth is
 dependent on  the vertical  temperature profile
 and is at a maximum in the afternoon.  The first
 2 columns of Table 1-4 present seasonal aver-
 ages of the daily maximum mixing depth and the
 degree of vertical dilution afforded.  The aver-
 age depth available for  mixing during autumn
 and winter is half that available in spring and
 summer.

 a On a scale of poor, moderate, good, excellent (Reference 9).
   During  the nocturnal hours, the earth's sur-
face is cooled as heat radiates away, the de-
crease in  air temperature with height is typ-
ically  less than during  the  day,  and vertical
mixing is correspondingly reduced. Frequently
the  cooling of the earth  after  sunset is rapid
enough that the temperature  gradient becomes
 inverted, i.e.,  the  lower air becomes cooler
 than  that above.  Such a  "radiation inversion"
 is  very stable and essentially eliminates any
 vertical dispersal of pollution until the inversion
 is  dissipated by the warming of the  earth in the
 morning.  The  last four columns of Table 1-4
 indicate the frequency of occurrence of inversion
 condition at  various  times  during  the day.
 Radiation inversions occur overnight about half
 the time in  all seasons, with slightly greater
 frequencies  in  summer and autumn.   A more
 obvious  seasonal difference is that nocturnal
 inversions tend to form  earlier in the evening
 and persist  later  into  the  morning  during
 autumn  and  winter than  during  spring  and
 summer.
   The  poorest  overall pollutant dilution, con-
sidering both horizontal dispersion (Table 1-3)
and vertical mixing (Table 1-4), is thus to be
expected in autumn, which is characterized by
a  relatively high  frequency both of persistent
inversions  and  of wind  speeds below 7 mph.
The   similar  high incidence of light  surface
winds and  low-level inversions  during summer
is usually compensated for by  good afternoon
mixing  and the  longer period each day during
which the mixing occurs.
   It  is also primarily during autumn that an
occasional high-pressure system stagnates over
some  portion  of the  eastern  United States,
frequently including  the Washington area. The
air in such  a stagnating  weather  system  is
generally  subsiding, and is warmed as it des-
cends; this  produces  a subsidence inversion,
which, in contrast to the nocturnal radiation in-
versions, may not entirely dissipate during day-
light hours and may persist for several days.
During these periods of atmospheric stagnation,
pollutants  can  accumulate to  record levels.
A  U.S. Weather  Bureau program12 that  fore-
casts such  stagnations noted  10 occurrences
(for  a total  of 28 days) over the Washington
area during the 3-1/2-year period from mid-
1960  through  1963.   Figure 1-5 indicates  the
general pattern  of occurrence of these  stag-
nations over the eastern U.S. during this period;
Washington  has experienced stagnations  more
frequently than most major eastern urban areas.

   Since this discussion of the atmospheric dilu-
tion  of air pollutants in Washington is based on
data from various periods over several years, it
should be considered only general.  Data from
1962 and  1963 are discussed more specifically
in Part 2.

 AIR  POLLUTION CONTROL ACTIVITIES*

   The  existing program  for control of air
 pollution in the District of Columbia has devel-
 oped over  a long period of time. Perhaps the
 earliest legislation on air pollution was passed
 in 1875.   This early  law, still enforced by the
 District  Department  of Public Health, covers
 so-called "public-health nuisances," which are
 concerned  with odors, noxious gases, and dusts
 resulting from certain natural causes or offen-
 sive industrial trades.

   In  1935 Congress enacted Public Law 279,
 the  District  of Columbia Smoke  Law,  which
 prohibits  the discharge of dense smoke from
 any   building,  any   stationary  or  locomotive
 engine, motor vehicle, place, or premises with-
 in the District of  Columbia;  the  law requires
 that all ashes, cinders, rubbish, dirt, and refuse
 be removed to a proper place and that  cinders,
 dust,  gas,  steam,  or  offensive or   noisome
 odors shall not be discharged from any building
 or place to the detriment or annoyance of other
 persons.   Limited  modifications and revisions
 have been made to the smoke law, but for the
 most part it stands as originally enacted. Since
1936,  a smoke  control  program,  through in-
spection of plans and issuance of permits for
fuel-burning equipment, has  endeavored to as-
sure  that  fuel-burning equipment installations
would not  create frequent  nuisances or viola-
tions  of the smoke law.  The smoke law is ad-
ministered by the District Department of Li-
censes and Inspection.

   Recent amendments to the  Traffic and Motor
Vehicle Regulations prohibit  motor vehicle ex-
haust  emissions darker than Ringleman No. 2.
During a required annual  inspection of motor
vehicles registered in the District, automobiles
are checked for excessive exhaust smoke, and
vehicles observed to be smoking  excessively
can  be required to appear  at  an inspection
station between annual inspections.  The ex-
haust  control ordinance is administered by the
District Police Department.

   Under Reorganization  Plan No. 5 of 1952,
the District Department of Public Health was
given  the  responsibility of  supervising com-
munity activities relating to occupational and
environmental   health.   This   responsibility
ranges from city planning to  investigation of
nuisances.   A comprehensive program for the
control of air pollution under this law has been
developed   by  the Health  Department and  is
awaiting implementation.

   In Montgomery and Prince Georges Counties,
Maryland, authority for air pollution control is
vested in the county health departments and con-
sists  primarily of investigation of complaints,
with  assistance from the state Department of
Health when necessary.  Neither county has a
smoke abatement program, but both have ordi-
nances and regulations establishing performance
standards   for  incinerators.    In Montgomery
County, open burning  of leaves and other com-
bustibles is limited to certain hours of the day.
In  Prince  Georges County, open burning  at
dumps  and  sanitary land  fills is prohibited.

   In  Arlington  County,  Virginia,  the  limited
air pollution activities are administered by the
Department of Inspections.  These activities are
directed primarily  toward the inspection and
licensing of boilers and incinerators, although
county  regulations also  limit the times when
leaves and  other combustibles  may be burned
in the open.  Investigation of complaints is the
responsibility of the County Health Department.
   Control activities are described as they existed during 1962-1963; since that time several local jurisdictions  have enacted new
   regulations, increased their staffs, and otherwise strengthened their control efforts.

-------
 In Fairfax County, Virginia, and in the City of
 Falls Church, air pollution control activities are
 administered by the County Health Department,
 with assistance  from the state Department of
 Health. In Alexandria, Virginia, the local health
 department  investigates complaints  and makes
 some limited investigations of specific problems
 with assistance from the  Virginia Department
 of Health.   Smoke  abatement activities are the
 responsibility of the smoke and boiler inspector.
 Individual backyard incinerators are permitted
 and  private open burning of leaves and  other
 combustibles  is  allowed,  although the  burning
 of construction  and demolition  wastes  is reg-
 ulated by a permit system.

    Following a period in June 1959 during which
 serious photochemical smog incidents occurred
 on  four consecutive days,  the Metropolitan
 Washington  Council of Governments, a volun-
 tary association, established  the Automobile
 Nuisance Abatement Committee.   The Com-
 mittee's task was  to supervise the  control of
 unnecessary  noise,  smoke,  and  fumes  from
 automotive equipment operated within the met-
 ropolitan area.   To meet the  increasing com-
 plexity of the air pollution problem, the Regional
 Air Pollution Advisory  Board has  superseded
 the original Committee.   Working through  the
 Council of Governments, this Board advises
 local officials in the metropolitan area  of  air
 pollution problems  and  proposes corrective
 measures.   Since 1961,  the Council of Govern-
 ments has  supported the operation of an area-
 wide, eight-station oxidant sampling network.
 Figure 1-6 indicates, for each network station,
 the proportion of afternoon samples that ex-
 ceeded 0.15 ppm oxidant  (phenolphthalein meth-
 od).* The downtown CAMP station recorded one
 of the higher frequencies of such days.

    The District  Department of  Public Health
 participates in the National Air Sampling Net-
 work (NASN), collecting bi-weekly suspended
 particulate  samples  on glass-fiber filters with
 a high-volume sampler.    Figure 1-7  presents
 the annual suspended particulate concentrations
 in  Washington, based on NASN data. Levels in
 1963 were about  typical  for the 6 years; levels
 in 1962 were the lowest recorded.

      AIR POLLUTION CONTROL ACTIVITIES

-------
CAMP STATION SITE


   The Washington CAMP Station is located on
the  southeast  corner  of the intersection of
First and L Streets, N. W., in a fairly dense,
older  residential-commercial  area.    During
1962  and  1963 First  Street,  a major traffic
artery,  was one-way southbound;  1962 traffic
data indicated that about 8000 vehicles passed
the station on an average weekday, mostly dur-
ing the morning traffic peak of inbound vehicles.
The only distinct point source of pollution in the
immediate vicinity is an elementary school on
the southwest  corner of the same intersection;
school  heating and waste  disposal activities
often produce slight but discernable effects on
the  pollutant  levels recorded at the  station.

   In an attempt  to  identify  any larger, more
distant, sources that exert an influence  at the
station, the hourly pollutant concentrations oc-
curring with  each of the wind  directions  (in-
cluding calms)  were plotted  in terms  of per-
centage of  the  annual  mean concentration of
each pollutant.  The resulting directional pat-
terns  for  1963 are presented  in Figure 1-8.
Data for  several  of the pollutants  did indeed
indicate some directional effect, with high con-
centrations  during  hours when  the wind was
from certain directions.  These  effects  and
their possible  causes are discussed in Part 2.

 SUMMARY OF RESULTS

 Pollutant Levels

   During 1962 and 1963 the CAMP station in
 Washington collected over 884,000 valid five-
 minute measurements* of gaseous air pollutant
 concentrations,  2748  two-hour  soiling  index
 values,  and  317 twenty-four-hour  suspended
 particulate samples. Table 2-1 summarizes the
 pollutant levels recorded and lists the periods
 for which data are available.

   Concentrations of the several gaseous pollu-
 tants ranged from maximum values 7 to 30 times
 the  mean  levels to  minima below the sensiti-
 vity of the instruments.   As is usual with air
 quality data,  most of the values recorded were
 numerically  low; however,  significantly  high
 pollutant levels did occur .t  Sulfur dioxide levels
 exceeded 0.1  ppm over 15 percent of the time,
 averaged over 0.25 ppm for an hour or  longer
 18 times, and on one occasion averaged 0.36 ppm
 for  an  8-hour  period.   Nitric oxide  levels
 averaged more than 0.25 ppm for an hour or more
 51 times, more than 0.50 ppm for anhour or more
 10 times, and on one occasion exceeded 1.0ppm.

   Nitrogen  dioxide  concentrations  varied far
 less widely, reaching a maximum of 0.3 7 ppm but
 rarely exceeding 0.10 ppm.  Totaloxidant levels
 averaged  0.10  ppm  or more  for  an hour or
 longer on 29 days during the 2 years and averaged
 more than 0.15 ppm for an hour or longer on five
 occasions; the maximum hourly mean was 0.22
 ppm and the maximum 5-minute value was 0.25
 ppm.  Since measurements of total oxidant are
 subject  to  a   negative interference by  sulfur
 dioxide, these values are probably  underesti-
 mates (see Appendix A).  The maximum total
 hydrocarbon concentration recorded was 20 ppm,
 but  levels exceeded 5 ppm only about 5 percent
 of the time.  Carbon monoxide levels exceeded
 20 ppm  for an hour or longer on 30 occasions
 and once averaged over 35 ppm for 8 hours.  The
 latter  incident included 1 hour of values over 40
 ppm  and  a  5-minute  maximum of 44 ppm.
   Although the higher concentrations constitute
only a small portion of the data, they generally
represent the bulk of the pollutant dosage t to
which  the  population is exposed'.  In addition,
they are usually not evenly distributed within the
data; rather, the highest concentrations, and con-
sequently the greatest portions of the exposure,
tend to  occur in  a relatively few periods of
sustained higher levels. For example, of the 883
ppm-hours total sulfur dioxide dosage in the 2
years, 402 ppm-hours, or 46 percent, occurred
during winter  months. On a shorter time scale,
a similar effect can be seen in the period men-
tioned  above (averaging 0.36 ppm for 8 hours),
which  occurred on February 6, 1963. Although
the 8 hours represents only  1.2 percent of the
total time  during the month,  the dosage during
this period amounted to over  4 percent of the
total exposure for the month.

   To  quantitate this effect in greater  detail,
Table 2-2 presents, for one season, the duration
of and  the dosage included in those periods when
the sulfur  dioxide  levels  reached  or  exceeded
0.13 ppm.  (This value was  selected to coincide
with a  comparable analysis for Cincinnati.) Note
that both higher  exposures and fewer occur-
rences are associated  with the longer events.
These  longer events account for a disproportion-
ately large amount of exposure to sulfur dioxide;
the 11  events  that lasted 8 hours or longer in-
cluded 41 percent of the dosage in 34 percent of
the total time that sulfur  dioxide was over 0.13
ppm.
   Pollutant  concentrations in Washington are
compared with those recorded at other CAMP
cities in Figure 2-1.  The levels were generally
intermediate among those from the six stations,
except for the total oxidant concentrations.  The
highest of the oxidant levels in Washington were
among the highest recorded at any of the stations;
these high levels were at least partially due to
particularly  low  levels  of sulfur dioxide in
summer —  the interference with oxidant mea-
surements was not  so serious (see Appendix A).
*The basic CAMP data on gaseous pollutants are neither precisely instantaneous atmospheric concentrations nor 5-minute average
 levels.  The measurements represent instantaneous values of the instrument response recorded at 5-minute intervals.  Each of these
 instantaneous values, however, reflects some degree of sample integration resulting from the characteristics of the instrument systems
 (see Appendix A).

tNote also that in terms of mass concentration units, such as /ig/m^,  the  values would from 700 to 2600 times larger numerically
 than the parts per million volume concentration used herein.

t Dosage is defined as the area under the time-concentration curve, in ppm-hours.

V,ariations in Pollutant Levels

   The mean pollutant concentrations in Table
2-1 are of little significance without some know-
ledge  of  the  variations around  these  levels.
Most of the pollutants measured in Washington
exhibited significant variability, both long-term
seasonal  differences  and  short-term diurnal
fluctuations.

   Figure 2-2 presents monthly mean levels of
the gaseous pollutants as percentages of their
respective 2-year mean concentrations.* Levels
of sulfur  dioxide and nitric oxide exhibited pro-
nounced long-term seasonal cycles, with concen-

 Figure 2-2.  Seasonal variation of  gaseous pollutant  levels.
trations an order of magnitude higher in autumn
and winter than in summer. Totaloxidantlevels
showed an opposite, but equally obvious, seasonal
pattern, due at least in part to changes in sulfur
dioxide  levels  and the attendant interference.
Nitrogen dioxide  levels  were below  average
during  summer  1962 and above average during
winter  1962-3,  but the difference  was slight
and was not repeated in  1963.  Monthly mean
levels of total hydrocarbon and carbon monoxide
also  varied significantly, but with  no obvious
seasonal patterns.   Total hydrocarbon levels
were  consistently well below the 2-year mean
during summer 1962 but not during summer 1963;
carbon  monoxide  levels  exhibited  even  less
semblance of any pattern. Interpreting the values
for these  pollutants is difficult,  however,  be-
cause the data are relatively sparse.

   Levels of each of the pollutants also exhibited
short-term diurnal fluctuations, with variations
ranging as widely as did the seasonal differences.
Figure  2-3  presents  the average patterns of
diurnal  variation.   Each bar  represents  the
average, over  all the days, of the  pollutant
concentrations during that  hour; these average
concentrations are then normalized as percent-
ages  of the  2-year mean.  Total oxidant levels
followed an  obvious pattern, nearly an order of
magnitude higher in the afternoon than at night;
as with the  seasonal differences,  some of  this
variation was  due to changing  levels of sulfur
dioxide interference.  Although the other pollut-
ants all exhibited patterns with similar shapes —
a  morning peak, an afternoon minimum, and an
evening increase followed by an early-morning
low — the magnitudes of the variations differed
among the pollutants.

   The  extent to  which  the variations of the
several pollutants tended to  occur together is
also  of interest;  such  relationships can be
quantitated with  correlation coefficients.t  To
indicate the degree of concurrent seasonal varia-
tion,  Table 2-3 presents  simple  correlation
coefficients  between monthly mean  concentra-
tions  of various pairs of the pollutants; total
hydrocarbons and carbon monoxide are omitted
because too few valid  monthly averages were
available.  The correlation of 0.50 between sulfur
dioxide and nitric oxide indicates that these two
  The dashed bars In Figure 2-2 and other figures represent invalid data-months, i.e., months for which  less than 16 days of component
  data was valid (see Part 3); as such, they should be considered only semi-quantitative. Missing bars indicate no valid data or only a
  very few data that are not  considered even qualitatively representative of the month.

 t The simple correlation coefficient (r) is a measure of the linear dependence between two variables.  By mathematical definition, the
  correlation coefficient can vary from -1 to+1. Two  variables that tend toward linear dependency will  have a correlation near -1 or +1,
  while independent variables will have a correlation near zero.

pollutants generally followed the same seasonal
pattern, as is apparent in Figure 2-2.  Monthly
average total oxidant levels correlated negatively
with both  nitric oxide  (r = -0.67)  and  sulfur
dioxide (r =  -0.81); this  negative relationship
reflects the opposite seasonal pattern shown for
total oxidant in Figure 2-2.

   To quantitate the degree to which the diurnal
variations were concurrent, Table 2-4 presents
simple  correlation coefficients between hourly
mean concentrations of  the several pairs of
pollutants for summer and winter. No confidence
limits  are  given because each  coefficient is
based on several hundred  concurrent measure-
ments.  All the pairs of pollutants, except those
involving oxidant, exhibited significantly positive
relationships; most of these correlations were
higher in winter than in  summer.  The hourly
concentrations of total oxidant were generally
uncorrelated with concentrations of  any  of the
other pollutants during winter, and were nega-

 THE EFFECTS OF ATMOSPHERIC
 DILUTION CAPACITY

    Both the long-term seasonal differences and
 the short-term  diurnal fluctuations in concen-
 trations of atmospheric pollutants are caused by
 variations  in the rate  at which pollutants are
 emitted into the atmosphere and in the  capacity
 of the atmosphere  to  dilute and disperse  the
 pollution.  Because dilution capacity affects all
 the pollutants in essentially the same manner, it
 is discussed separately here before the several
 pollutants are  discussed individually  in more
 detail.

    The effects  of changes in atmospheric dilu-
 tion capacity are most apparent in the similarity
 of several of the diurnal variation patterns in
 Figure 2-3.  The best dilution conditions gener-
 ally occurred in the afternoon, when the depth of
 the unstable mixing layer was greatest  and wind
 speeds were highest; thus afternoon levels of all
 the pollutants  but total  oxidant were usually
 minima.   In the evening, when the atmosphere
 was generally stable and winds generally lighter,
 pollutant emissions were not rapidly dispersed,
 and atmospheric  concentrations i n c r e a s e d.
 These poor dilution conditions continued through
 the night, and the decrease  in pollutant concen-
 trations during the very early morning hours was
 primarily due to a decrease in emissions.  The
 peak levels in the morning after sunrise resulted
 partially from the concurrent increase  in emis-
 sions  of  most of the pollutants with the start of
 the day's  activities,  and  partially from  the
 morning  "fumigations."*  The relative signifi-
 cance of  these two causes varies among  the
 pollutants,  and  is discussed  later in greater
 detail.   Total  oxidant levels  did not  follow a
 pattern similar to those of the other pollutants
 because  the  oxidant levels in the atmosphere
 depend so much  upon  solar radiation  that this
 effect overshadows differences caused  by other
 factors.  The seasonal differences  in  average
 pollutant levels  caused the magnitude,  and to a
 certain extent the shape, of the diurnal variation
 patterns  to  change from season to  season, as
 seen in Figure 2-4.
   The  general features of the  patterns, as
determined by the daily cycles of dilution capa-
city,  sunlight, and emission strength, remained
consistent in all seasons.
   The long-term seasonal differences in atmos-
pheric dilution capacity of course affected pollut-
ant levels  just as did the diurnal fluctuations;
however, the effects cannot be readily discerned
in Figure 2-2 because of the overriding seasonal
variations  in emissions.  The expected effects
can be partially defined, on a relative basis, by
meteorological  variables.   The  surface wind
speeds and maximum mixing depths during 1962
and 1963 are  summarized in Table 2-5; these
summaries indicate that daytime dispersion and
dilution  capacity were above-average in 1962
and 1963,  particularly in the summer months
(compare with Tables 1-3 and 1-4).

 RESULTS-INDIVIDUAL POLLUTANTS
   Although  the effect of atmospheric dilution
 capacity  on pollutants levels is generally  the
 same for all pollutants, most of the other factors
 influencing  atmospheric  pollutant concentra-
 tions, particularly the nature of and variations in
 sources,  affect the several pollutants  quite
 differently.  For  this reason, the following de-
 tailed  discussion of  the  data considers each
 pollutant  or group  of pollutants  separately.

 Sulfur Dioxide

   Sulfur dioxide pollution  in the Washington
 area results almost exclusively from the  com-
 bustion of  sulfur-bear ing  fossil fuels, parti-
 cularly coal and fuel oil. Estimates of emissions
 of sulfur dioxide  from the several combustion
 sources are presented in Figure 2-5.

   The  majority  of these emissions  originate
 from elevated stacks at the large heating instal-
 lations  and power plants, most of which are south
 of the CAMP station  (Figure 1-3).  There is no
 evidence, however, that emissions from anyone
 of these large fuel users unduly influenced sulfur
 dioxide levels at the station; in fact, directional
 patterns of 1963 hourly concentrations, shown as
 percent of seasonal mean concentration (Figure
 2-6), indicate that levels were generally higher
 with winds from the north and east.  This effect
 may represent emissions from nearby residen-
 tial areas or the industrial area to the northeast;
 it may  be merely a coincidence, with frequent
 northeast winds during the morning peak levels;
 or it may indicate that such winds are preferen-
 tially associated  with unusually cold  weather
 systems and associated increased fuel use. Note
 also in  Figure 2-6 that the highest average levels
 were associated with calm winds only during the
 summer;  this  effect  indicates that the higher
 sulfur dioxide levels generally result from emis-
 sions brought to the station by the wind, rather
 than being associated with poor horizontal dis-
 persal  of  emissions  from  nearby  sources.
   Sulfur dioxide sources can be divided into two
general  categories depending on the variability
of their  emissions throughout the year.  In one
category, including  electric power  generation,
use of fuel in commercial and industrial proces-
ses, and vehicular exhaust, the emissions vary
little from season to season; in the second cate-
gory, the use of fuels for domestic, commercial,
and  industrial  space heating  follows a distinct
seasonal pattern, as do the corresponding emis-
sions. Figure  2-7 presents monthly mean sulfur
dioxide concentrations superimposed on a pattern

electric  power   generation,  industrial,  com-
mercial, and vehicular sources. The upper area
of the emission pattern represents the distribu-
tion of monthly average heating demand (assumed
proportional to degree-days, base 65° F) normal-
ized to  a scale such that the mean of the  emis-

dioxide  level.   The differences  between the

 pattern of bars representing atmospheric sulfur
 dioxide  levels  and the pattern  of  emissions in
 the background thus  roughly approximate the
 influence of variation in the atmospheric dilu-
 tion capacity, within the limits of the assumptions
 made about emissions.  Efforts to relate these
 differences  to meteorological parameters were
 unsuccessful because of a lack of sufficiently
 detailed data on vertical temperature gradients.
 Figure  2-7 does  indicate, however, that with
 sulfur dioxide the  seasonal changes in emission
 rates influenced pollutant levels more signifi-
 cantly than did  seasonal differences in meteoro-
 logical factors.

    An attempt to weigh the relative significance
 of emission rates  versus meteorological factors
 with  respect to short-term fluctuations in pollu-
 ant concentrations can  be made by  inspecting
 diurnal variation patterns, such as the seasonal
 patterns in Figure 2-8.  These indicate the pre-
 viously  noted  large  seasonal  differences  in
levels; the shapes of the patterns, however, were
all similar, following the general pattern shown
for all the pollutants in Figure 2-3 and 2-4. The
spring and  autumn patterns in particular were
strikingly similar, as might be expected during
these transitional seasons. The differences be-
tween afternoon and evening levels were largely
due  to  the  difference in atmospheric  dilution
capacity, while the decline in each pattern after
10 p.m. was presumably due to decreasing home
heating and  electric power demand.

   The causes of the morning peak levels in each
diurnal pattern are of particular interest, since
these levels were generally the highest for the
day;  however, the relative significance of morn-
ing increases in source strength and of  fumiga-
tions in  causing  these  peaks  is  not obvious.
Some evidence that both are involved is offered
by Figure 2-9, which presents average patterns
of diurnal variations on weekdays and on  Sundays.

 nor the overnight sulfur dioxide emissions that
 contribute to it would be expected to exhibit any
 particular variation through the week; the differ-
 ences in Figure 2-9 thus indicate some difference
 in morning sulfur dioxide emissions, presumably
 the lackof space heating in office and commercial
 buildings and the lessened electric power de-
 mands on Sundays. On the other hand, the typi-
 cal morning peak is not completely absent from
 the Sunday pattern, an indication that fumiga-
 tions are at least partially responsible.

    Frequency distributions provide a more sta-
 tistically  quantitative manner  of studying the
 variability of pollutant levels.  Frequency dis-
 tributions* of the 5-minute sulfur dioxide data
 by  month,  season, and year  are presented in
 Table 2-6,  and the 2-year distribution is plotted
 with the high and low seasons and the high and
 low months in Figure 2-10. The seasonal differ-
 ence  in sulfur  dioxide  levels is  quantitated
 dramatically  in  Figure 2-10;  in the  winter of
 1962-1963,  nearly 90 percent of  the  5-minute
 values equalled or exceeded  0.05 ppm, a value
 exceeded by only 6 percent of the summer 1963
 data.   The near-identity of the curves for the
 highest month and highest  season reflects the
 relative uniformity of pollutant levels during the
 winter.

    Table 2-6 also includes frequency distribu-
 tions  of sulfur dioxide concentrations  averaged
 over  various periods  longer  than 5  minutes.
 There is no difference among these distributions
 (except for  the  several  maxima)  until the
 averaging time  exceeds 1 hour.  The fact that
 the 5-minute and  10-minute  distributions are
 identical reflects only the 10-minute averaging
 time  of  the instrument (see  Appendix A); the
 identity of the 5-minute and 1-hour distributions,
 however, indicates that sulfur dioxide levels in
 Washington do  not  generally  fluctuate  widely
 within a short time interval, but vary  gradually
 over periods of several hours.

    The highest hourly average (0.48  ppm) was
 nearly as high as the maximum 5-minute value
 (0.56  ppm),  but  about twice  the  highest daily
 mean (0.25  ppm).  These maxima were all re-
 corded during the morning and early afternoon of
 February  6,  1963 (see Table  3-15). These un-
 usually high levels appear to have resulted from

a combination of increased emissions from space
heating  (the temperature averaged 35°F from
3 p.m. on February 5th through 3 p.m. on the 6th)
and severely limited atmospheric dilution capa-
city (wind speeds on  the 6th averaged only 2.9
mph and the 7 a.m. sounding indicated a tem-
perature inversion  that  limited  mixing  to  the
lowest 200  to 300 feet of the atmosphere).  The
presumably high emissions  of sulfur dioxide into
such  a  limited  volume  of  air  were no doubt
responsible for the record  peak. These condi-
tions were associated with low-pressure weather
systems moving past the Washington area from
the south, and with a weak high-pressure system
to the north, producing  light  northerly winds.
Weather Bureau observers  reported smoke and
haze throughout most of the day.
The interpretation of frequency distributions and their application to CAMP data are discussed in Appendix A.

Oxides of Nitrogen

   Nitric oxide and nitrogen dioxide are produced
by any high-temperature combustion process in
which air is an oxygen source.  Such processes
include the combustion of petroleum fuels  for
transportation and of fuels for space heating or
for industrial and commercial purposes.  Be-
cause of the heavy  traffic density and minimal
industrial activity, vehicular emissions are the
major source of oxides of nitrogen in Washington
(see Figure 2-11).

   The directional patterns of nitric oxide con-
centrations for 1963, Figure 2-12, indicate high-
est levels from the northeast in winter, similar
to the slight effect seen in sulfur dioxide levels,
and from the west  southwest predominantly in
other seasons. It is not apparent whether these

effects were due to particular concentrations of
pollutant  sources  in  these directions,  or to
generally lighter winds from these directions.
The highest nitric  oxide levels were recorded
during hours of calm and result from the accumu-
lation  of low-level,  disperse emissions  from
vehicles during periods of poor horizontal dilu-
tion.  Distinctly higher levels also were recorded
with autumn winds from the north and north-
northwest;  these were the  result of northerly
winds during a period of high nitric oxide con-
centrations  occasioned by an atmospheric stag-
nation in October 1963. The directional patterns
of nitrogen  dioxide in  Figure 2-13  indicate no
distinct and consistent effects.

   An estimated  emission pattern for oxides of
nitrogen, constructed in a manner similar to
that for  sulfur dioxide, is presented in Figure
2-14; the bars represent the sums of the monthly
mean nitric oxide and nitrogen dioxide concen-
trations actually recorded. The estimated emis-
sion pattern in the background represents con-
centrations  resulting from  electric power de-
mand and vehicular fuel consumption, which vary
only slightly throughout the year, and from heat-
ing fuel consumption, which of course follows a
seasonal pattern.  The atmospheric levels gen-
erally followed the emission pattern; the differ-
ences, presumed to represent the variation in
atmospheric dilution,  are similar to  those for
sulfur dioxide (Figure 2-7).

   In additon to changes in atmospheric dilution
and source strength, ambient levels of the oxides
of nitrogen  also depend upon a chemical equili-
brium in the atmosphere, which involves a com-
plex series of  chemical reactions between the
oxides of nitrogen and hydrocarbons photolyzed
by solar radiation.  The effect of these photo-
chemical reactions is a net conversion of NO
into NO£ and the formation of reaction products
such as  ozone  and oxygenated organics, which
typify  "photochemical smog."  This role of the
oxides of nitrogen is  of particular  interest.

   Were it not for this photochemical conversion
of NO into NO2, levels  of  each of the oxides
would be expected to show a pattern of seasonal
variation similar to that of total nitrogen oxides
in Figure 2-14.  Instead, nitric oxide levels ex-
hibited a seasonal pattern more accentuated than
that of total oxides of nitrogen, with values rang-
ing nearly an order of magnitude from summer to
winter; monthly nitrogen dioxide concentrations,
conversely,  exhibited no consistent seasonal pat-
tern and were much less variable than the total,
ranging only about 25 percent above and below
the 2-year mean (Figure 2-15).  This difference

in  patterns  resulted  from increased  photo-
chemical conversion of NO into NO.2 in the more
sunny  months, when emissions of both oxides
were lowest; the conversion subtracted from the
already  low nitric oxide levels and added to the
minimum nitrogen dioxide levels.

   This  seasonally varying difference between
levels  of the two oxides of nitrogen is seen also
in Figure 2-16, which compares their average
monthly  diurnal variation patterns  (values for
January  1962 and January 1963 are averaged to-
gether,  and  so on for each monthly pattern).
Most of the diurnal  patterns in Figure  2-16
reflect the  typical  diurnal cycle of afternoon
minima, higher nocturnal levels, and morning
peaks.   The interactions of emission rate, at-
mospheric dilution capacity, and NO-NOz  con-
version  rate introduced seasonal modifications
of these features  and, in the winter nitrogen
dioxide  patterns, eliminated them completely.

   Maximum  dilution  in the atmosphere  and
maximum photochemical conversion into nitro-
gen  dioxide  produced  consistent afternoon
minima  in the nitric oxide curves, just as the
same factors produced low summer levels in the
seasonal pattern.   These minima ranged from
over 0.04 ppm in February to less than 0.005
ppm in the summer months, following the season-
al changes  in solar radiation intensity.   The
afternoon nitrogen  dioxide levels reflected the
influence of sunlight as a balance between the
formation of NC>2 from NO and the further photo-
chemical formation of other nitrogen-containing
reaction products.  In winter, with minimal solar
radiation and afternoon mixing, the high morning
concentrations  of nitric oxide were converted
slowly to nitrogen  dioxide, which accumulated
sufficiently to produce higher levels in the after-
noon than overnight. In summer, with greatly in-
creased  solar  radiation,  the formation  of NO2
from NO was rapid  enough to produce a distinct
morning peak similar to but later than the nitric
oxide peak; good atmospheric dilution and further
photochemical conversion then produced distinct
afternoon minima in the patterns.

   The  evening and  nocturnal portions of the
diurnal patterns in Figure 2-16 exhibit the effects
of evening rush-hour traffic and decreasing at-
mospheric dilution, with the attendant concentra-
tion of oxides of nitrogen emissions. During the
winter months, nocturnal radiation inversions
had frequently  formed  by the time  of the peak
evening  traffic  emissions, and photochemical
activity had generally  ceased, permitting nitric
oxide to  accumulate rapidly to produce distinct
peaks from 5 to 7 p.m. in the winter patterns.  In
summer, the period of insolation was prolonged
and the city changed to Daylight Saving Time, in
effect shifting the evening traffic peak 1 hour
earlier, so that the peak emissions occurred at
a time when the photochemical conversion rate
was still high. Consequently, the June, July, and
August patterns  exhibit peaks in the nitrogen
dioxide curves at 4 to 5 p.m. (EST) and the ex-
pected nocturnal  increase in nitric oxide levels
does not occur until late in the evening. During
autumn the increasingly early formation of poor
dilution conditions favored an increase in evening
levels of both of the  oxides of nitrogen by in-
hibiting the dissipation of emissions from the
evening rush-hour  traffic,  and the  decreasing
level  of  solar radiation caused  more  of the
rush-hour  emissions  to  be accumulated in the
form of nitric oxide.  Thus by November, the
patterns  indicate both oxides  of nitrogen in-
creasing at 4 to 5 p.m., but  only nitric oxide
being accumulated overnight.

   The  most  distinct feature of  the oxides  of
nitrogen patterns in  Figure  2-16 is the  peak
levels in the morning. Because the largest por-
tion of oxides of nitrogen emissions in Washing-
ton are from motor vehicles — a disperse, low-
level type of source — very little of the morning
peak  levels  can be  attributed  to  fumigation
effects; note the  nearly complete elimination of
the morning peak concentrations on Sundays and
holidays  in Figure 2-17.  Rather, the morning
oxides of nitrogen maxima are the direct result
of the emissions from morning rush-hour traffic,
although  the magnitude of the peaks and the time
of their occurrence are also affected by the rate
of dispersion  of  the vehicular emissions in the
atmosphere and  by the rate of  photochemical
activity.   The patterns in Figure 2-16 for the
winter months exhibit high, broad nitric oxide
peaks, since both the rate of atmospheric dilution
and  the  rate  of photochemical  conversion  to
nitrogen dioxide are relatively low in the morn-
ing. During the summer the dilution capacity of
the atmosphere  and the rate of  photochemical
activity are much greater, and both of these
factors  are active  in reducing the atmospheric
nitric oxide levels during the time when the rate
of emissions from vehicular traffic is increasing
rapidly.  As a result the nitric oxide patterns for
the summer months in Figure 2-16 exhibit much
lower and  more  sharply defined morning peaks
than are seen in  the winter patterns. Note also
the  earlier  occurrence of the  peaks  in  the
warmer months.  This is partially due to the in-
creasingly early ventilation and  photochemical
activity,  but also  reflects the  shift of  human
activity in the city to Daylight Saving Time in the
summer.  The change in local time has the effect

of  shifting  the rush-hour  traffic peak 1 hour
earlier with respect to the time scale in Figure
2-16, since the CAMP station continues reporting
data on  Eastern Standard Time.   The effect is
seen  clearly in a comparison of the April and
May patterns and of the October and November
patterns of Figure 2-16. In both cases the morn-
ing nitric oxide peaks exhibit a distinct 1-hour
shift, not only in the time of the peak concentra-
tions,  but also in the time of the  initial upward
inflection at the beginning of the peak.

   The shape of the morning peaks in the nitrogen
dioxide patterns in Figure 2-16 also changes con-
siderably from month to month.   In the winter
months,  when the level of solar radiation is low,
the photochemical conversion of NO into NO2 is
quite slow; hence the nitrogen dioxide patterns
exhibit a slow rise through the morning to maxima
in the afternoon. In the summer, when conversion
is much more rapid, the nitrogen  dioxide levels
rise quite rapidly following the nitric oxide peak,
and then decrease as ventilation  increases and
as  further photochemical  reactions  consume
nitrogen dioxide in the  formation of oxidants.
Thus the patterns for the warmer months exhibit
a distinct morning peak in nitrogen dioxide con-
centrations, lagging about an hour after the nitric
oxide peak and exceeding it in magnitude during
the sunniest months.

   Since the diurnal variation patterns in Figure
2-16,  as well  as  others in this volume, are
compiled from average hourly pollutant concen-
trations, definition of the time of  occurrence of
the peaks is not precise. Figure 2-18 illustrates
the morning-peak portions of diurnal variation
patterns compiled from 15-minute average nitric
oxide  concentrations; the patterns are for  the
5  weekdays immediately before  and after  the
change from Daylight Saving to Standard Time in
October  (1962 and 1963 are averaged together).
The times  of the peaks  are  more  precisely

human activity with respect to Standard Time
results in  a distinct 1-hour shift in the time of
the peak concentrations.   Figure 2-18 is taken

   Frequency distributions of oxides of nitrogen
concentrations are compiled in Tables 2-7 and
2-8 and are presented graphically in Figure 2-19.
The distributions for averaging times longer than
5 minutes  show little difference except for the
several  maxima;  even  the maxima  changed
significantly only for averaging times exceeding
1 hour.  This similarity may be due in part to
sample averaging in the instrumentation systems
(See Appendix A), but also reflects the fact that
concentrations of the oxides of nitrogen generally
do not vary rapidly.
   The  differences between the two families of
curves  in  Figure 2-19 illustrate the difference
in overall variability between the two oxides of
nitrogen.   Nitrogen  dioxide varied  less, both
seasonally and diurnally. The curves are more
closely spaced and have a  much lower slope.
The inflections at  the upper ends of  the curves
for October  1963 result from a lengthy atmos-
pheric stagnation during that month; the stagna-
tion was also  responsible for the exaggerated
diurnal variability in the October  curve of Fig-
ure 2-16.

   The  highest daily average concentration of
nitric   oxide  also occurred in October  1963
(0.26 ppm on the 18th) during  the period of
atmospheric  stagnation.    The  shorter-term
maxima, however, occurred on December 26-27,
1963, during an overnight radiation inversion
(see Table 3-49).

Total Oxidant
   As generally used,  the  term  total oxidant
includes all constituents of the atmosphere that
are capable of exerting an oxidizing effect. Oxi-
dizing substances  are rarely emitted as such
from pollution sources, but are generally formed
in the atmosphere by photochemical reactions.
Some  of  the total  oxidant found  in the lower
atmosphere  consists of  ozone  formed  from
oxygen at high altitudes by high-energy solar
radiation and  brought  to lower  levels by  air
currents.  The remainder of  the  total oxidant
consists of ozone and a wide variety  of other
oxidants  formed  in  the lower atmosphere by
reactions of man-injected pollutants, primarily
oxides of nitrogen and hydrocarbons.

   The substances produced in the lower atmos-
phere are the  oxidants  of primary interest in
air pollution; they have been implicated as  the
cause of the  adverse  effects associated with
photochemical  smog, and are, at any rate, a
measure of the smog-producing reactions. Thus
the oxidant levels of significance  are  those of
the daylight hours, and the use of averaged values
dilutes the value of total oxidant as a smog indi-
of 5-minute oxides of nitrogen data.
   cator by including data for the nocturnal hours.
   That is, an average  of the oxidant data recorded
   between 6 a.m. and  6 p.m. (0.019 ppm) would be
   a better comparative indicator of photochemical
   smog than the mean of all available data (0.012
   ppm) presented in Table 2-1. For  this  reason,
   the seasonal variation pattern of total oxidant in
   Figure   2-20 is  presented  in terms  of  both
   nocturnal and daytime means for each month.

      The daytime means in Figure 2-20 are gener-
   ally higher than the nocturnal averages, as ex-
   pected,  but  the  most striking  feature is the
   seasonal pattern of  the daytime means. Average
   daytime concentrations  of total oxidant ranged
   from essentially zero  during several winter
   months to about 0.040 ppm during the summers,
   while the nocturnal means  ranged from near-
   zero only as high as 0.015 ppm.

      Although  oxidant levels would be expected to
   be lower during the less sunny months (because
   of  reduced  photochemical activity),  the near-
   zero winter levels recorded also include a nega-
   tive interference effect from the high winter
   concentrations of sulfur dioxide.*  During  Jan-
   uary 1962,  when sulfur dioxide levels averaged

0.09 ppm, the recorded total oxidant concen-
tration  averaged 0.01 ppm (the  minimum non-
zero level recorded) for only 11 hours during the
month,  and reached a 5-minute maximum value
of only  0.03 ppm.  During January 1964, with an
equal amount of sulfur dioxide eliminated by an
absorber device,  the  recorded oxidant concen-
tration  averaged 0.01 ppm for the entire month
and  reached a 5-minute maximum of 0.08 ppm.
   Because  the occurrence of measurable oxi-
dant levels,  even  if  not  always  quantitative,
carries a certain measure of information, the
oxidant data have been included in Part 3 of this
report;  because of the interference, however, the
data and analyses must be interpreted with care.

   Figure 2-21 presents the seasonal patterns of
diurnal variation in the recorded total oxidant
levels.   Although  the  seasonal  differences in
magnitude of the  oxidant  concentrations  are
obvious, the  shapes of the patterns are essen-
tially the same. The patterns indicate the pre-
dominant effect of solar radiation intensity, with

increased  levels during  the  daylight  hours
despite optimum dilution  conditions,  and very
low levels overnight.

   Because the portion of atmospheric oxidant
resulting from photochemical reactions  in the
lower atmosphere is the primary indicator of the
extent of the photochemical smog problem, it is
worthwhile  to  attempt to  quantitate this com-
ponent by determining the background level of
oxidant.  The average total oxidant concentration
was  obtained for those hours between 10 p.m.
and 4 a.m.  in the summers when the interfering
sulfur dioxide  averaged  less than 0.005 ppm
(i.e., a zero hourly mean was reported).  The
calculated  value was about 0.01 ppm of oxidant,
presumed to be ozone brought down from high
altitudes or nitrogen dioxide, which can exert
some oxidizing effect.

   An attempt  to relate summer oxidant levels
to measurements of total solar radiation taken
in Sterling, Virginia, indicated no simple rela-
tionship for short-term measurements, presum-
ably because other  factors also exert an influ-
ence.  On a more gross basis, however, the effect
of solar radiation is easily demonstrated. Fig-
ure  2-22 presents average diurnal patterns for
summer days classified into two groups accord-
ing to solar radiation measurements, and indi-
cates  higher  oxidant  levels  with higher solar
radiation.

   Assessing the seriousness of the photochemi-
cal smog problem  from measurements of total
oxidant levels requires estimates  both  of the
effects produced by various  levels of reaction
products and  of  the frequency of  occurrence of

 those levels.  The Regional Air Pollution Advis-
 ory Board11 for metropolitan Washington accepts
 0.25 ppm of oxidant (phenolphthalein method) as
 the level at which eye irritation and vegetation
 damage  may  become  problems and 0.15 ppm
 (phenolphthalein) as the levelat which smog odor
 may first become evident.*   The frequency with
 which these levels  are exceeded can be deter-
 mined by examining frequency distributions of
 the data.

   Frequency distributions of 5-minute total oxi-
 dant data from the  Washington CAMP station are

analysis makes a great deal of difference in the
distribution.  The  curve of all the data is well
below  the distribution of summer daylight data
because of  the large portion of nocturnal data
and the heavy sulfur dioxide interference during
much of the year.  Thus, although only about 2
percent  of  all  the Washington  oxidant  data
reached or  exceeded 0.08 ppm, 11  percentof the
daytime (7  a.m.-8 p.m.) data that were largely
unaffected by sulfur dioxide reached this level,
and nearly 2 percent of such data exceeded 0.13
ppm.  These levels occurred on 78 days during
the year when oxidant levels averaged 0.08 ppm
or more for an hour or longer, including 9 days
when oxidant concentrations reached 0.13 ppm or
greater  for an hour or longer.

   Total oxidant concentrations during 1963 ex-
hibited a directional effect, highest with winds
from the southeast quadrant, as indicated in Fig-
ure 2-24; since oxidants are not directly emitted
from sources, such a directional effect was un-
expected. The effect may be attributable to more
favorable conditions for photochemical oxidation
with southeasterly winds, since nitrogen dioxide
levels  showed a similar tendency,  or  it may be
merely the  result  of the coincidence of south-
easterly winds with high oxidant levels caused
by other factors.   No  obvious explanation is
available.   Note also that the total oxidant  con-
centrations  associated with  calm winds  were
lower than average, especially in the winter and
summer, presumably because periods of calm
winds  occur most frequently  at  night,  when
oxidant levels are routinely low.

Total Hydrocarbon

   Gaseous  hydrocarbon  compounds in  the at-
mosphere consist of stable hydrocarbons,  such
as methane,  which do  not participate  in at-
mospheric photochemical reactions, and other
"reactive"  compounds,   such as  olefins  and
aldehydes, which are in effect raw material for
such smog-producing reactions.   The non-re-
active  portion consists of a constant geophysical
level of methane of about 1 ppm15  plus variable
contributions of methane and other stable hydro-
carbons  from gas  main  leaks, natural decay
processes, sewage treatment, motor vehicle ex-
haust,  and similar sources. The reactive hydro-
carbons  in   the atmosphere result essentially
from the combustion or  evaporation of organic
compounds, primarily gasoline.  In the Washing-
ton  SMSA about  80 percent of an estimated
average  hydrocarbon emission of 640 tons per
day  is attributable to motor vehicles. Roughly
half of these vehicular emissions  are reactive.
  ^Comparable levels in terms of the potassium iodide method used by CAMP are about 0.13 and 0.08 ppm, respectively.

   Emissions of reactive hydrocarbons in Wash-
ington would be expected to exhibit little seasonal
variation because the slight winter contribution
from fuel consumption for space heating is off-
set by a decrease in vehicular fuels consumed.
Since  the  methane   contribution from  other
sources  can  vary  greatly, however, the long-
term pattern of total atmospheric hydrocarbon
levels would not be expected to remain constant,
nor to necessarily follow seasonal differences in
atmospheric dilution  capacity.
   The monthly hydrocarbon concentrations did
not, in fact, exhibit  any definitive pattern of
seasonal variation (Figure 2-2), in part because
the data were quite sparse. There was, however,
a  distinct  difference between  levels during the
April-August periods of the two years; levels
averaged  less than 1  ppm from April  through
                                      August  1962 and  more  than  2 ppm  during the
                                      similar period of 1963.  This difference cannot
                                      be readily attributed to differences in meteoro-
                                      logical factors.  In fact,  the data on surface wind
                                      speed  and  maximum  mixing  volume listed in
                                      Table 2-3 indicate that the opposite effect would
                                      have been expected; i.e., conditions were more
                                      favorable for pollutant dispersal during April-
                                      August  1963 than during, the  similar period of
                                      1962.  The lack of a similar sizeable change in
                                      levels  of  any other pollutant tends to confirm
                                      that gross meteorological differences offer no
                                      explanation for the difference.

                                         The pattern of short-term variations in total
                                      hydrocarbon levels  was both more distinct and
                                      more explicable. The average patterns of diurnal
                                      variation  are presented by  season in  Figure
                                      2-25.  The patterns illustrate the difference in
                                      levels   between  the two summers,  but their

 shapes offer no further clue to its  cause.  In
 general,  the patterns exhibit the morning peaks
 and higher  nocturnal levels previously noted
 as typical of most of the pollutants, although
 these features are somewhat erratic because of
 the limited number of data.  The morning peaks
 were due primarily to morning traffic emissions,
 since  there are essentially  no  major elevated
 sources of hydrocarbons in the Washington area.

    Because  of  the  strong  influence  of motor
 vehicle exhaust on emissions of hydrocarbons in
 Washington, a relationship between atmospheric
 levels and weekly traffic patterns would be ex-
 pected.   Figure 2-26 presents diurnal patterns
 of hydrocarbon levels averaged separately for
 weekdays and for Sundays and  holidays.  With
 vehicular traffic  the  primary variable,  the
 patterns  indicate the essential elimination of the
 morning  peaks on Sundays, and about a  10 per-
 cent difference in  mean levels.   The  slightly
 higher levels in the very early morning  on Sun-
 days  may  be  attributable  to  higher  evening
 traffic density on Saturday evenings.

    Another interesting facet of the morning peak
 concentrations is that their formation depends on
 relatively low wind speed. Figure 2-27 presents
 diurnal  patterns  of  weekday  data classified
 according to wind speeds from 6 to 8 a.m.  The
 rapid dispersal  of low-level  traffic emissions
 with high  wind speeds prevented the accumula-
 tion of hydrocarbon to high peak concentrations.

cent were 5 ppm or higher.  The curve for the
season  with the highest levels, Autumn 1963,
exhibits an upward inflection at the high end due
to a period of atmospheric stagnation during
October.

   Average hydrocarbon concentrations  asso-
ciated  with  winds from different directions
during 1963  are presented in Figure 2-29. To
reduce the  diluting effect of the nondirectional
background of  unreactive  hydrocarbons, 1 ppm
was  subtracted before the conversion to per-
centages  of the  seasonal  mean.  Although the
directional  effects are not striking,  they are
qualitatively similar to those for nitric oxide,
with little pattern in winter,  distinctly higher
levels  from the southeast  during the rest of the
year, and a secondary  effect from the north in
autumn.   This similarity  is as expected, since
vehicular emissions contribute  significantly to
atmospheric levels of both nitric oxide and total
hydrocarbon.

 Carbon Monoxide

    Carbon monoxide is produced by the incom-
 plete combustion of any  organic fuel.  Almost
 all such fuel except gasoline is used in instal-
 lations where  combustion   takes  place  with
 excess air and is relatively efficient; thus gaso-
 line combustion in motor vehicles is the primary
 source of  carbon monoxide pollution.  Because
 the efficiency  of  combustion in motor vehicles
 varies  widely  with  many   factors,  including
 vehicle maintenance,  carbon monoxide emis-
 sions have not been estimated.

    The expected  seasonal  pattern of carbon
 monoxide emissions would generally depend on
 the traffic patterns. During the colder months,
 automobile engines can operate more efficiently
 because the colder, denser air provides a higher,
 more  efficient air-fuel ratio. Hence if most of
 the traffic in an  area consisted of vehicles on
 long trips,  with  engines fully  warmed up and
 operating  efficiently,  carbon monoxide emis-
 sions  would be  expected to decrease  in the
 winter. On the other hand, if most of the traffic
 consisted of vehicles  making short trips, with
 engines operating  cold and  probably partially
 choked, carbon monoxide emissions would tend
 to  increase.  It would  be  expected  that the
 CAMP  station in Washington, because of its loca-
 tion, would  be influenced primarily  by emis-
 sions  from  short-trip commuter  traffic, and
 that  carbon monoxide levels would tend to be
 higher  during the winter  months.

    The monthly mean carbon monoxide concen-
 trations in Figure  2-2 do not indicate any  defi-
 nite seasonal pattern, in large part because valid
 data were  too sparse.   The  average diurnal
 variation patterns  in Figure 2-30 do indicate
 somewhat higher  carbon monoxide concentra-
 tions in winter.

    The shapes of the diurnal patterns in Figure
 2-30 indicate  that  the carbon monoxide levels
 varied in  essentially the same manner  as did
 most of the other pollutants,  although the curves
 are  somewhat erratic  because of the small
 number of  valid data.  A distinct evening rush-
 hour peak is evident only  in the winter curve,
 and the morning peak in the summer pattern was
 shifted 1 hour earlier than the peaks in the spring
 and autumn patterns because of the shift to Day-
 light Saving Time; each of these features is
 similar to  the  effects  apparent in  the nitric
 oxide and total hydrocarbon patterns.

    Diurnal patterns of carbon monoxide concen-
 trations on weekdays and Sundays are compared
 in  Figure 2-31, and patterns for days with high
 winds and low winds from 6 to 8 a.m. are com-

 also similar in many respects to the directional
 patterns  of total hydrocarbon in  Figure 2-29.
 These similarities reflect the common origin of
 the two pollutants in vehicular emissions.

    Frequency  distributions of the carbon mon-
 oxide data are presented in Table 2-10 and Fig-
 ure 2-34.  The only feature of particular note is
 the curve  for November 1963;  examination of
 Table 3-136 indicates several discrete periods
 of hourly  mean levels in the range from 15 to
 20 ppm; these produce  the  disproportionately
 high "bump" on the frequency distribution curve
 for November.

   In addition  to the six gases monitored at the
 Washington  station,  particulate pollution  was
 measured  during  1963.   Figure 2-35 presents
 monthly mean soiling index values, total sus-
 pended particulate  concentrations,  and gross
 beta  radioactivity  levels of  the particulate
 matter.  Soiling index values, which primarily
 reflect the fine particulate matter in the air, ex-
 hibited a  seasonal pattern similar to that  of
 sulfur dioxide, suggestive of emissions from
 coal and oil consumption. The weight concen-
 trations of  the  total suspended particulates,
 however, varied only slightly except for October,
 when a prolonged atmospheric stagnation occur-
 red (October 15-22: see Table 3-148). The gross
 beta radioactivity  level of the particulate matter
 exhibited   distinct seasonal  differences, with
 higher levels in the spring. This seasonal effect
 is typical  of  radioactive pollution originating
 from  atmospheric  experiments  with  nuclear

weapons;  such pollution is carried down from
the upper atmosphere  by seasonal changes in
the  upper  winds  during  the  winter season.

   Frequency   distributions  of  the total sus-
pended particulate concentrations and gross beta
radioactivity data from the CAMP station are
presented in Tables  2-11 and 2-12 and in Fig-
ures 2-36 and 2-37. Suspended particulate con-
centrations  averaged 98 Mg/m3, about 15 per cent
lower  than the  average  at  the National Air
Sampling  Network site (Figure 1-6). This differ-
ence may have been partially due to a difference
in the  sampler shelters  used at the  two sites
(See Appendix A).

   The  diurnal variation of  the soiling index
values is presented in Figure 2-38.  Each season-
al pattern exhibited higher levels in the morning;
the peak  shifted  in  time  somewhat with the
seasons, but the 2-hour averages permit only the
largest changes to be seen. Higher levels in the
evening or overnight were less pronounced than
the morning peaks, and did not follow an obvious
pattern.

  ATMOSPHERIC STAGNATIONS AND PHOTO-
  CHEMICAL SMOG
    The  Eastern portion of the  United States
  occasionally  experiences the stagnation of an
  entire  weather system,  usually a  warm high-
  pressure system or anticyclone, which tends to
  permit the accumulation of pollution to higher-
  than-normal levels.   Such stagnations affected
  the  Washington area  on five occasions during
  1962 and  1963.  Two of these were  extensive
  stagnations that covered much of  the Eastern
  United  States  for  prolonged periods; they in-
  cluded  Washington from November 29 through
  December 4,  1962,* and from October 15 to 19,
  1963.   Figures 2-39 and 2-40 compare diurnal
  variation patterns compiled for these periods
  with "normal" patterns compiled for the months

           1962 stagnation (November 29  - December  4).

excluding the stagnation periods.  There were no
valid data  during the 1962 stagnation for the
oxides of nitrogen or total oxidant, and none for
total hydrocarbon during the 1963 event
   During the  1962  stagnation, pollutant levels
were elevated primarily overnight; the after-
noon minima were not drastically affected. Table
2-13 presents the stagnation-to-normal ratios
of peak  hour  and daily mean concentrations.
Note that during the  stagnation  the average
levels  of each of the  three pollutants for the
enitre  day exceeded  the peak hourly levels ex-
perienced normally.

   During the 1963 stagnation (Figure 2-40) most
pollutant levels were more severely increased,
as shown in Table 2-14.  Sulfur dioxide levels
were only slightly increased,  perhaps because
emissions  were  lessened  by reduced space
heating in the relatively fair and warm weather
during the stagnation period.

   The levels of nitric oxide, by contrast, were
 extremely  exaggerated.    The  stagnation in-
 creased pollutant levels most severely during the
 nocturnal and morning hours, when nitric oxide
 levels are normally high; the very low inversion
 severely limited the dispersion  of  the peak
 emissions from rush-hour traffic.

   In general, the 1963 stagnation increased the
 average and peak pollutant levels to more  than
 twice normal levels.

   The high levels of nitric oxide during the 1963
 stagnation  would be  expected to  fuel photo-
 chemical smog  reactions, and in fact, the total
 oxidant levels were higher than normal. Figure

for October  16, 17, and 19, the 3 days during
the stagnation when the sulfur dioxide inter-
ference  could  be eliminated from the oxidant
data.   The  patterns together  form  a  typical
photochemical  smog sequence, although data on
hydrocarbon  concentrations were missing. The
peak nitric oxide  levels at 8 a.m. and 10 p.m.
were  extreme; the nitrogen dioxide peak in the
                                           morning was also quite high. The morning peak
                                           of nitric oxide resulted from rush-hour traffic
                                           emissions  into the limited  volume of air. The
                                           nitrogen dioxide peak 2 hours later resulted from
                                           photochemical conversion of NO to NO2; further
                                           photochemical reaction then produced  the high
                                           oxidant levels in the afternoon.  The shapes of
                                           the  patterns  in  Figure 2-41  are  typical of
                                           photochemical  smog  formation, although  the
                                           nitric  oxide peaks were unusually  high.  The
                                           oxidant levels  were not the highest recorded,
                                           but were unusual for October.

                                              The  highest  atmospheric levels  of oxidant
                                           for  the 2-year  period occurred on 2  days in
                                           June 1963, shown in Figure  2-42. Data for these
                                           days also  indicate a  "classic"  photochemical
                                           smog incident, although  again the hydrocarbon
                                           data were missing. The peak morning levels of
                                           oxides  of  nitrogen were again  occasioned by
                                           rush-hour traffic emissions, the more favorable
                                           atmospheric dilution in summer being reflected
                                           in the lower peak nitric oxide concentrations.
                                                                                 •

                                           ences were the result of the differences in solar

ADDITIONALPERCENTILE CONCENTRA-
TIONS FOR 1-AND 24-HOUR AVERAGING
TIMES

   Many air pollution control jurisdictions have
adopted  or  are  considering  criteria  against
which  to judge air  quality, or upon which  to
base  control  legislation.   These  criteria are
often  based  on averaging times other than 5
minutes  and may  well be based on percentiles
higher than  those available in the frequency
distributions tabulated in the sections onindivi-
ual pollutants. To facilitate  comparisons of air
quality  in Washington with  any such criteria,
Table  2-16 presents the 99-percentile  concen-
trations for 5-minute CAMP data and for 1-hour
and 24-hour  averaged data, and the 99.9-per-
centile concentrations for 5-minute and 1-hour
data.   Two years  of data do not provide enough
          24-hour averages for the 99.9-percentile to be
          meaningful, since 0.1 percent of 2 years time is
          less than one 24-hour averaging interval.

PART 3:
DATA TABLES

-------
                             PART  3:  DATA  TABLES
   The  results  of the first 2 years of CAMP
operations in Washington are summarized in the
following  tables.  Although it is intended  that
this volume can thus serve as a reference, the
data are necessarily condensed; more detailed
compilations  are  available.   Any  interested
person  or  group can obtain further information
by arrangement with the Chief of the Air Quality
Section, Laboratory of Engineering and Physical
Sciences,  Division of Air Pollution, at the Robert
A. Taft  Sanitary Engineering Center.

GASEOUS POLLUTANTS

   Table  3-1  lists and indexes those months
for which valid data are available and for which
summary   tables  are included.   Tables  3-2
through 3-135 present hourly  average concen-
trations by month for the gaseous pollutants.
Values  in these tables are the arithmetic means
of the  5-minute values in the clock hour  be-
ginning  at the time indicated. An average is not
calculated  if the hour is  considered an invalid
data hour,  i.e., if fewer  than seven 5-minute
values were valid. Similarly, if a calendar day
had fewer  than 13 valid data hours, it is con-
sidered an invalid data day and the entire row of
averages for that day is deleted. The reason for
this  procedure,  which results in the loss  of a
few valid  hourly averages, is that the data  that
are  thus  lost are usually concentrated at the
beginning or end of the day. Since pollutant con-
centrations show considerable diurnal variation,
the inclusion  of data for  such days would in-
troduce a definite  bias into the  monthly mean
concentrations.

   The  first summary line at the bottom of the
tables   (titled  MONTHLY  MEAN)  contains the
arithmetic means  of the hourly  averages,  and
hence represents the pattern of diurnal varia-
tion  for the month.  Again by the same validity
criterion,  this average is not calculated unless
16 or more hourly averages are present.  The
second and third summary lines are the number
of and maximum of the hourly averages in  the
column.

   The first summary column at the right of the
tables (titled DAILY MEAN) is the arithmetic
mean* of the 13  or more hourly averages com-
prising  the row,  and the second is the number of
such valid hourly averages.  The third summary
column,  however, is  not the maximum hourly
average for the day, but the maximum 5-minute
value included  in the hours of valid data during
the day.  The largest of these is not necessarily
the maximum for  the  month if any valid hours
have been  deleted as part of an invalid day; the
maximum  5-minute concentration during the
month  is best obtained from the tables of fre-
quency distributions,  which are compiled with-
out considering the validity of any hour or day.

   Two summary  figures appear in the lower
right corner. The first is the monthly average,
an arithmetic mean, and appears  only if 16 or
more days  were valid (a valid data month). The
second is the total number  of valid hours in-
cluded  in the  table, which offers some basis for
judging the representativeness of the monthly
average.   (A 31-day  month has 744 possible
hours;  a 30-day month, 720; and a 28-day month,
672.)

SOILINGINDEX

   Tables 3-136 through 3-145 present soiling
index values at the  CAMP station by  month.
Each value was  obtained from a 2-hour in-
tegrated  sample beginning at the time indicated
in the  column  heading.  A missing  value in-
dicates that the sample was not taken or was
invalid because of instrument malfunction.
   The  first summary line  (titled MONTHLY
MEAN) represents the arithmetic mean of the
2-hour  average values in the column, and is
calculated  only if  16  or  more days are repre-
sented. The first summary column (titled DAILY
MEAN) is  the  arithmetic mean of the 2-hour
values  for the  day; if fewer than seven such
values  are present, the daily mean is not cal-
culated,  and the data are not included in the
summaries,  but the component 2-hour values
for the day are not deleted from the table as
is done  with the  data on gaseous  pollutants.

   The other summary columns and rows  are
the number of  and maximum of the respective
2-hour values.  Three summary figures appear
in the lower right corner; the mean and maximum
value for the  month are the upper left and lower
right  figures  respectively,  while the center
figure  is  the total number  of values.  (A 31-
day month could have 372  such values;  a 30-
day  month,  360; and  a 28-day  month, 336.)
 All the summary calculations in the tables are performed before the hourly overages are rounded.

SUSPENDED PARTICULATE MATTER

   Tables 3-146 and 3-147 present the results
of analyses of 24-hour particulate samples: the
gross  weight of suspended particulate matter
and  the  gross  beta radioactivity of  the parti-
culate  matter,  respectively.   Each value re-
presents a  sample collected from about noon
to noon, ending on the date indicated, with the
exception of those indicated by asterisks; values
so marked represent 48-hour samples, usually
during  a weekend,  which  are entered  in the
tables as  identical values  for  2  days.  The
summary row contains the arithmetic means of
the various values for the month, including the
duplicate pairs.

         APPENDIX  A:  INSTRUMENTATION  AND  METHODS
INSTRUMENTATION

   The gaseous  pollutant instrumentation was
originally developed and fabricated by Beckman
Instruments, Inc., under contract with the Public
Health Service; the calibration techniques were
developed by the CAMP staff.  When subsequent
field  operations  have  disclosed difficulties,
instruments have been modified by CAMP per-
sonnel; all the instruments have been so modified,
and  some  of  the changes have  been major.
In addition, the calibration techniques, parti-
cularly  for the  "wet" instruments, have been
continuously  studied  and  frequently  revised.

   The gas-measuring instruments, as modified,
are thus  unique.  The other instruments at the
CAMP stations (high-volume and spot-tape par-
ticulate samplers) are, in contrast, intentionally.
similar to many others  used throughout  the
country.

Sulfur Dioxide

   The SO2 instrument is based on a conducto-
metric analysis.  The sample air stream is
drawn through  a dilute  sulfuric  acid solution
containing  hydrogen  peroxide.   SO2  in  the
sample  stream  is  oxidized to further ionize
the solution.  Any change in  the  solution con-
ductivity,   compared  to  a reference  cell,  is
proportional to  the SC-2  concentration,  and is
measured in a range corresponding to 0-2 ppm
of SO2.

   This  instrument  is very stable and presents
few calibration difficulties. The electronics are
checked daily by switching to a built-in circuit
that  simulates 1.5 ppm S02.   At  least weekly,
the air flow is manually eliminated to simulate
a zero condition. The upscale range is static-
ally  calibrated at least monthly with standard
solutions,  and very little drift  has been ex-
perienced.  Dynamic  calibration is performed
at least once a year  with standard gas mixtures.

   The response  time of the SC>2 instrument is
about 8  to 12  minutes;  this  lag  causes  some
smoothing  of concentration peaks of 10-minute
duration, which are believed  to occur in some
locations.  Since the  instrument response is
largely  a  function of the reagent movements,
improvements are being sought in the liquid flow
controls and design details.
   The  conductometric  analysis is  considered
very  accurate; although it is  sensitive to any
ionizable  substance, it is  essentially  specific
for SO2 (including accompanying 863)  because
other ionizing substances do not occur to any
significant extent in the normal urban atmos-
phere.
Oxides of Nitrogen

   The NO2 instrument utilizes a colorimetric
technique,  incorporating Saltzman  reagent  to
quantitatively  form a  magenta  color. 17  The
color is measured by a ratio photometer (oper-
ating at 545 millimicrons) that has a 90 percent
response  equivalent to 1  ppm of NO2.   Such
colorimetric  analysis  is  considered accurate
within 10 percent.
   After the NO^ has been extracted, the sample
 air  stream  is bubbled  through  an acidified
 potassium permanganate  solution to convert
 NO in the stream to NO2-  It then passes into
 an identical instrument, which thus measures
 the original NO concentration as NO2.
   These  instrument  systems  are subject to
considerable zero drift;  hence they are purged
(with  carbon-filtered  air) daily at a time when
pollutant levels are usually low, the zero cor-
rection being recorded daily and reset when the
drift becomes excessive.  The scale  range is
calibrated with colored optical filters at least
biweekly and also after each cleaning or adjust-
ment  of the photometer.  In addition,  both in-
struments are dynamically  calibrated periodi-
cally with standard gas mixtures.
   The response time of the NOx instruments is
about 15  to  20 minutes, part  of which is in-
herent in the  reaction that produces the reagent
color change;  the remainder  is  due to  en-
gineering features  of the instruments necessary
to insure  the desired precision. Although this
response time is the longest of any of the CAMP
instruments,  it is  not  considered  a major
problem  because  NOX levels are believed to
fluctuate less rapidly than those of other pol-
lutants.
                                                                                         211

-------
Total Oxidant

   The  total  oxidant instrument  reacts  the
sample  air stream with a neutral  10  percent
potassium  iodide  (KI) solution, releasing free
iodine in the presence of  oxidizing agents.  A
ratio colorimeter  (operating at 345 millimi-
crons)  measures   the color  of the liberated
iodine against a  reference,  operating  in  the
range 0-0.5 ppm of oxidants.   The instrument
will  record  the  presence  of any substance
capable of oxidizing iodide in the KI solution,
such as ozone, the peroxyacetyl nitrates, to a
lesser  extent  nitrogen  dioxide,  and  others.


   Sulfur  dioxide  produces  a  negative  inter-
 ference, driving the oxidation reaction back to-
 ward the neutral potassium  iodide. The effect
 of  this interference on  the instrument, and
 hence on  the recorded data,  can be seen in
 Figure  A-l.   The  figure presents  recorded
 traces  of  oxidant  levels from  two instruments
 operating  side by side,  one  with and one with-
 out  an absorber   device  to  remove  SO2J  the
 simultaneous trace  of  SO2  levels is  also  in-
 cluded.   The interference effect  is  obvious:
 during  the morning, when  SO2 levels were high,
 the  oxidant  instrument without the filter re-
 corded essentially no oxidant, although the other
 indicated levels up to 0.08 ppm. As SO2 levels
 decreased, the unfiltered instrument began to
 record the  oxidant, and by  mid-afternoon  the
 two   instruments   were responding similarly.


   This interference is  of course very trouble-
 some,  and dictates extreme caution in inter-
 preting any  type  of total oxidant data from any
 location where SO2 occurs  simultaneously in
 appreciable  amounts.   The large proportion of
 time at such sites for  which zero oxidant con-
 centration is reported  represents  those times
 when the oxidant concentration was truly zero
 plus those times when SC>2  completely sup-
 pressed the oxidant measurement;  any non-zero
 oxidant level recorded  may  also be lower, by
 an unknown amount, than the actual atmospheric
 concentration. Thus the only unequivocal state-
 ment that can be  made is that the appearance
 of a measured oxidant value indicates the pres-
 ence of that concentration or higher in the atmos-
 phere.
    If the SC>2 interference can be quantitated, of
 course, simple calculations  can provide  more
 meaningful oxidant information.   Such a cor-
 rection has been used  with some sucess  for
 short periods of  data,  but  cannot be applied
 generally  to  all  of the  CAMP data.  The ab-

    sorber  devices to remove SO2 from the sample
    stream, and hence prevent the chemical inter-
    ference, have been employed by CAMP routinely
    since January  1964, but none were operational
    during  the  1962-1963 period reported herein.

       Apart from the SC-2 interference, the oxidant
    instrument  system presents  sensitivity  and
    stability problems, and  satisfactory data are
    acquired only with extensive and careful main-
    tenance.  Frequent calibration similar  to that
    described for the oxides of nitrogen system is
    required, including a  daily instrument purge
    from 1  to 2  a.m.

    Total Hydrocarbon

       The  total hydrocarbon instrument utilizes a
    flame ionization  detector, in which the  sample
    air  stream  is introduced into a  hydrogen-air
    flame,  where the hydrocarbons are dissociated
    in the intense  heat.  The positive  carbon ions
    produced by the dissociation are collected by an
    electrode  above  the  flame, and  the  current
    produced is proportional to the number of carbon
    atoms ionized.  The  operating range of the in-
    strument can be as sensitive as 0-10 ppm carbon
    atoms,  although CAMP operates the instrument
    on a scale  of  0-40 ppm to insure  inclusion of
    all peak levels.

       The  flame ionization technique  is well estab-
    lished and  is considered very precise,  and the
    instrument  operates with  little difficulty.  Be-
    cause  the  response  of the hydrocarbon in-

strument  is  normally  almost  instantaneous,
CAMP has incorporated an integrating flask into
the system to provide data averaged over about
5  minutes.  The system  is dynamically  cali-
brated twice weekly on standardized air-methane
mixtures in the  near-zero and 20 ppm ranges.

Carbon Monoxide

   The CO instrument is a short-path monobeam
infrared analyzer, based  on the molecular ab-
sorption of infrared radiation by carbon mon-
oxide; it is an interesting variant of the more
conventional long-path infrared analyzers.  The
single  infrared  energy  beam is directed in
series, as indicated in  Figure A-2, through a
sample cell containing the flowing sample air
stream, and through sample and reference com-
partments  of a dual detector unit, charged with
CO-argon mixtures.

    The sample detector compartment is charged
 with  a low concentration of CO, which absorbs
 a quantity of radiant energy dependent upon the
 amount previously absorbed  by the sample air
 stream.  The reference  detector compartment
 contains a high CO concentration, which absorbs
 enough radiation to be largely unaffected by the
 slight fluctuations in  incident energy produced
 by varying  absorption in the sample  cell and
 sample detector unit.  It thus provides  a very
 stable reference, with which  absorption in the
 sample detector is differentially compared.  In
 each   compartment,  the  energy  absorbed  is
 measured by pressure transducers.

    The CO  instrument  can have a very rapid
 response, but about 5 minutes integration time
 has been  introduced in the same manner as with
 the hydrocarbon system.  It is extremely sensi-
 tive along the entire range (0-100 ppm), and is
 dynamically calibrated twice weekly in the man-
 ner described for the hydrocarbon instrument.
   Both water vapor and carbon dioxide absorb
infrared radiation at wavelengths very near the
wavelength of CO.  The degree of such inter-
ference is periodically measured by filtering
the sample stream through columns of silica
gel and ascarite. When interferences are signi-
ficant, the CO data are declared invalid and not
reported.   Because of such interference  early
in the operation  of the  CAMP program, valid CO
data were  often sparse, and on occasion non-
existent, during 1962  and  1963.   Since  early
1964, this  problem has been largely eliminated
by adding an infrared filter, which narrows the
radiation band to  converge on the CO absorp-
tion wavelength.

Participates

   The  high-volume air samplers in use at the
CAMP  stations  are of the type  used by  the
National Air  Sampling  Network (NASN) and by
most  state and local  agencies.   Particulate
samples are  collected  on  8- by 10-inch glass-
fiber filters considered 100 percent efficient for
particles  about 0.3 micron  in diameter and
larger; vertical influent airflow velocity limits
the sample to particulates  smaller than  about
100 microns in diameter.

   The filters are analyzed in the same manner
as routine NASN samples. They are equilibrated
at 75° F and 50 percent relative humidity over-
night  prior to determination of both  tare and
total  particulate weights.   Gross beta radio-
activity* is measured  with a proportional gas
flow counting chamber when the filter is 4 days
old and again several days later.  The apparent
half-life so determined is used to calculate the
reported values  representing activity on the day
sample was  collected; these  values are also
corrected for counter  efficiency, filter absorp-
tion, and self-absorption.   More  detailed des-
criptions of analytical procedures  and sampling
methods are  available  in the 5-year summary
of NASN operations.18

   The multi-purpose shelters used during 1963
to house the particulate instruments at the CAMP
stations  are  not identical  with those used  for
the high-volume samplers at the NASN stations.
Although the differences are slight and were
not expected to affect  the collection  of parti-
culates,  later checks  have revealed that  the
particulate data from  the  CAMP stations are

 Division of Air Pollution.

 systematically lowered by an unknown amount.
 Thus any comparison with  NASN data is open
 to doubt.

    Soiling index measurements are obtained at
 the CAMP stations with a standard automatic
 paper tape  sampler.   Air  is drawn at 0.25
 cfm through a  1-inch circular  "spot" on What-
 man No. 4 filter paper tape for a 2-hour period,
 the sampler advancing the tape automatically.
 The  tapes  are  periodically  removed and  the
 percentage of  light  transmission through  the
 soiled  spots  is  compared to that of  the clean
 tape.

 DATA RETRIEVAL SYSTEM

    Each of the gaseous pollutant instrument sys-
 tems produces an electric output signal, which
 drives  a  strip  chart  recorder.  At 5-minute
 intervals, the  signal is momentarily diverted
 to  an analog-to-digital recorder, which records
 the magnitude  of the signal on punched paper
 tape.   Thus  the basic  data represent the  in-
 stantaneous instrument response value recorded
 at  5-minute intervals.

    The raw  data are transferred from punched
 paper tape to punched cards for computer use
 by  an automatic translator.  The actual pollutant
 concentrations  are calculated  by a  computer
 program from  the raw  data, station operator's
 logs, and the known instrument parameters, and
 are stored  on  magnetic  tape  for subsequent
 analysis.  Throughout the several steps of this
 process, the time synchronization and complete-
 ness of  the  data are  checked by hand.   All
 unusually high concentrations or abrupt changes
 in  concentration are  manually  checked against
 the recorder charts before the data are accepted
 as  valid.

 DATA ANALYSIS

    The information presented in this volume is
 derived from the data through the application of
 several analytical techniques.   Some of these
 are common statistical methods, whereas others
     have been modified specifically for use with the
     CAMP data. The tremendous quantities of data
     have  necessitated the programming of even the
     simplest  operations  for the digital  computer
     facility of the Robert A.  Taft Sanitary Engineer-
     ing Center. The application of frequency distri-
     bution analysis to the CAMP data is sufficiently
     specialized to warrant its description here, both
     as background to the results reported in Part
     2 and as an illustration of the type of additional
     material available on request.

        A  frequency  distribution  analysis  summa-
     rizes the frequency of occurrence of the various
     pollutant concentrations  recorded. The pollutant
     concentrations tabulated in the frequency distri-
     bution tables represent the concentration that
     was  not exceeded  by the specified percentage
     of the total data considered.  Although such a
     distribution is properly termed a relative cumu-
     lative frequency distribution, the  phrase "fre-
     quency distribution", or merely "distribution",
     is used in the text for convenience.  Frequency
     distributions of this  type provide a convenient
     means for determining the median pollutant con-
     centration  and  data  for other  specific fre-
     quencies, such  as the concentration exceeded 2
     percent of  the time  or the concentration below
     which the  pollutant level fell 10 percent of the
     time.
        The graphic  presentations of frequency dis-
     tributions are drawn to logarithmic-probability
     scales; if the logarithms of the pollutant con-
     centrations   were  distributed according  to  a
     normal probability  distribution,  the  resulting
     curve  would be linear,  and the data  would be
     described  as being  log-normally distributed.
     The slope  of a  curve plotted to such  scales is
     a function  of the variance  of the population of
     data  included,  a steeper  slope representing
     more  variable  pollutant levels.  The curve's
     vertical placement is determined by the magni-
     tude of  the  pollutant concentrations.  Thus a
     curve  that  has an  inflection  represents data
     recorded from two  relatively distinct  popu-
     lations with differing variances or levels.
