                       ABSTRACT
    The objectives of this pilot study were to develop a prelim-
inary evaluation of air pollution in Jacksonville and to determine
whether fluoride and sulfur dioxide concentrations were sufficient
to cause damage to vegetation that had occurred in the area.  The
study consisted of an emission inventory, a meteorological inves-
tigation, an intensive  short-term study of downtown Jacksonville,
and an industrial area study.   Pollutants sampled for included
sulfur dioxide, oxidants, nitrogen dioxide, carbon monoxide,
hydrogen sulfide,  fluorides, and suspended particulates.  During
the study fluoride concentrations were high enough in certain
parts of the city to cause damage to sensitive plants; sulfur
dioxide and oxidants were also present at significant levels.
Results of  the study also indicated that photochemical smog
is produced over Jacksonville, that pollutants from Jacksonville
are transported across the St. John's River, and finally, that
several pollutants constitute a potential problem  in the city and
should be evaluated further.

                A PILOT STUDY  OF

                AIR POLLUTION IN
          JACKSONVILLE,  FLORIDA

                      SUMMARY
GENERAL

    National attention was focused on air pollution in Jackson-
ville, Florida, in 1948, when nylon apparel disintegrated on
local residents; the cause:  air pollution.  In the years  that
followed,  an ever increasing number of complaints were regis-
tered regarding air pollution in the Jacksonville-Duval  County
area.  In  the spring of 1961, damage to vegetation occurred;
the prime suspect: air pollution.

    Dr. Wilson T. Sowder, then Florida State Health Officer,
on May 31,  1961,  requested of Dr. W. H.  Aufranc,  Regional
Health Director, United States Public Health Service,  Region
IV, Atlanta,  that a pilot study of the Jacksonville air pollution
problem be  conducted jointly by the Public Health Service, the
Florida State_Board of Health,  and the Jacksonville  City Health
Department.  In response to this  request,  the Technical As sis -
Branch of the Division of Air Pollution of the Public Health
Service sent a five-man team to Florida to work with State Board
of Health  and City Health Department personnel in evaluating air
pollution problems in the Jacksonville area.  During the initial
stages of  this evaluation,  State and city personnel were to be
trained in survey techniques,  so that future programs could be
carried out  with a minimum of Federal assistance.

    The objectives of this pilot study were (1) to develop a
preliminary opinion as to whether the city of Jacksonville
has a generalized air pollution problem and (2) to determine
whether certain pollutants,  fluorides and sulfur dioxide, were
present in the atmosphere in concentrations capable of  producing
the damage to vegetation that had been experienced in the Jack-
sonville-Duval County area.

    To accomplish the first objective, a 1-week intensive  in-
vestigation was  carried on in downtown Jacksonville at  Hemming
Park from August 3 to 10,  1961.

-------
                                   JACKSONVILLE AIR STUDY
     To accomplish the second objective, additional studies
were conducted from. August 4 to  12, and September 5 to  13,
1961, in the area in which damage to vegetation had occurred.
Two fertilizer plants, located in the industrial area of Jackson-
ville, were not in production during the first phase of this study.
Pollutants sampled in this study included fluorides, sulfur diox-
ide, hydrogen sulfide, nitrogen dioxide, and particulates.

     The air quality  data collected during these studies indicated
that certain air pollutants  (fluorides,  sulfur dioxide and oxidants)
were present  in significant levels in the air over Jacksonville.

FLUORIDE

    Airborne  fluoride concentrations  capable of causing damage
to sensitive plants under proper growth conditions were found
during the study.  The data indicated that conditions for trans-
port of objectionable concentrations of airborne fluorides across
the St. John's River into the Arlington area do occur.

HYDROGEN SULFIDE
    Although no high concentrations of hydrogen sulfide were
observed during this  study, darkening of lead-base paints and
paints containing mercury-base fungicides  in the Arlington area
subsequent to  the study indicates that a problem due to hydrogen
sulfide does exist there.

OXIDANTS
    Oxidant concentrations observed during this study, al-
though less than those measured in Los Angeles during severe
pollution, indicate that photochemical-type smog similar  to
that produced in the  Los Angeles area is being produced in the
city of Jacksonville.  The  maximum oxidant level measured by
the phenolphthalin method  during August 3 to 10,  1961, was
0. 162 parts per million (ppm) by volume (as hydrogen peroxide).

SULFUR DIOXIDE

     Sulfur dioxide concentrations observed during the non-
heating season in which the study was conducted were generally
low.  The maximum concentration observed during this study
was 0. 174 ppm,  a value similar to  maximums observed in
larger cities  of the country. *> 2 This high value probably was
due to emission of sulfur dioxide from a major source.  It can
be expected that sulfur dioxide levels would be higher during the
winter months in Jacksonville. Major sources of sulfur dioxide
may  cause periodic  occurrence of concentrations higher than
those observed,  at certain locations in the Jacksonville area,
possibly reaching levels that would cause  damage to sensitive
plants.

-------
                   CONCLUSIONS

    As a result of the urban and industrial area investigations
it is concluded that:
    1.  Photochemical smog is being produced in the air over
Jacksonville.
    2.  Concentrations of fluorides occurred in certain parts
of Jacksonville during the study that could cause damage  to
sensitive plants.
    3.  Pollutants from the city of Jacksonville are transported
across the St. John's River.
                     INDICATIONS
     1.   Hydrogen sulfide concentrations were not of the mag-
nitude known to cause discoloration of paints containing lead
pigments and/or mercury-base fungicides.  Subsequent to the
study, an incident of darkening of paints occurred in the Ar-
lington area.  Therefore, it is evident that a hydrogen sulfide
problem exists in that area.

     2.   Sulfur dioxide concentrations did not reach levels known
to cause damage to vegetation.  It appears possible, however, for
sulfur dioxide concentrations  during the heating season to reach
levels capable  of causing damage to sensitive plants,  particular-
ly in localized  areas downwind of major sources of sulfur diox-
ide.

     3.   The data collected also indicate that the fine particu-
lates causing soiling and the sulfur dioxide measured at Hem-
ming Park are  being emitted to the atmosphere from the same
source or sources.   A general relationship between wind di-
rection and sulfur dioxide concentrations measured during the
industrial area investigation was demonstrated.

-------
              RECOMMENDATIONS
    Levels of certain air pollutants found during these stu-
dies indicate that the Jacksonville-Duval County area has
air pollution problems.  The following recommendations are
therefore made:

    1.  A full-time air pollution control program should be
activated.  This program should encompass the area affected
by the air environment receiving the pollutants emitted in the
Jacksonville-Duval County area.  The study conducted in
August-September, 1961, demonstrated that pollution from
the city of Jacksonville can affect areas outside of the city.
Visual observations indicate that meteorological conditions
do occur that could transport pollutants from outside the
city into the  Jacksonville area. The air pollution control
program should encompass the area within a distance of 25
miles or more from the city of Jacksonville.

    2.  The  air pollution control program should include fur-
ther evaluations of air pollutant levels and source emissions,
and monitoring of possible effects of air pollutants on plants
and property.  Such studies are necessary to determine
whether progress  is being made in protecting the air environ-
ment  of the Jacksonville area, and whether new air pollution
problems are arising.
    3.  A continuing  micrometeorological study  should be
an integral part of this  program.  Such a  study -would not
only allow a better understanding of relationships between
source emissions  and ground level concentrations, but -would
provide the necessary scientific data  required for planning
proper utilization of the air environment.

    4.  Since completion of this study,  certain of the industrial
plants have instituted additional control procedures, and have
made operational changes to decrease pollutants  emitted to the
Jacksonville atmosphere.  A repeat of the study conducted in
the industrial area would provide information on the effective-
ness of these control procedures and process changes.

                  INTRODUCTION
BRIEF DESCRIPTION OF THE AREA

    Greater Jacksonville straddles the St. John's River at a
point approximately 15 miles from the Atlantic Ocean.  Eighty-
two percent of Duval County's I960 population of 455, 411 live
in the 130-square-mile area classed as urban by the U.  S.
Bureau of the Census.   Over 200, 000 individuals live in the
city of Jacksonville proper.
    Jacksonville, the county seat and one of the larger cities
of the State,  is a manufacturing and transportation center as
well as a seaport.  The deep -water port at Jacksonville, and
its location at the hub of Florida's railway and highway systems,
has made the city an important distribution center for Northeast
Florida and Southeast Georgia.

    Major industries are food processing, pulp  and paper,
chemicals,  and  shipbuilding and  repair.  Manufacturing is
quite diversified,  with no one industry accounting for over
15 percent of the county's manufacturing employment. ^

ORIGIN AND PURPOSE OF THE STUDY

    Air pollution in Jacksonville received national recognition
in 1948 with the famous incident  in which nylon blouses and
stockings disintegrated on the wearers.   Evidence pointed to
air pollutants emitted in burning of high sulfur residual fuel
oil as the cause.  Since that date, public interest in air pol-
lution problems has grown to the extent that in I960 over 1700
complaints of odors, dust,  soot, smoke, and damage to prop-
erty and vegetation were received from Duval County residents
by the  city, county, and state public health agencies.

    In the  spring of 1961,  severe vegetation damage occurred
in the residential areas on both sides of the St. John's River.
The center of the damaged area  was the industrialized section
located in the East Jacksonville waterfront area.  Preliminary
investigations by the State Board of Health, the Jacksonville
City Health Department, and the State Agricultural Extension
Service indicated that the probable cause of the damage was
one or a combination of the air pollutants (particularly fluorides
and sulfur  dioxide) thought to be  present  in that area. ^ Figures
1 and 2 indicate the geographical distribution of  elevated con-
centrations of fluorides and sulfates in vegetation (althea leaves)
sampled.   Following an investigation of the affected area in
June of that year,  Dr.  C.  S.  Brandt, an authority on air pollu-
tion damage to vegetation, reported in part:

                                   JACKSONVILLE AIR STUDY
     "... Since there had apparently been considerable re-
     covery since the initial development of the  symptoms,
     there is some uncertainty as to actual cause and. severity.
     However,  sufficient injured material remained showing
     characteristic fluoride burn to implicate this agent.  The
     analytical data that you have  on hand would tend to confirm
     this observation.
     "While there was  no  evidence, at the time of my visit,  of
     acute sulfur dioxide injury,  your analytical data of markedly
     elevated sulfate levels (in vegetation) in the area and the
     description of the early 'kill1 lead me to suspect that this
     may have been a contributory factor to some of the early
     dramatic effects.

     "The bleached type of injury now being seen in this area
     on various species, is not readily identifiable as charac-
     teristic of any single known air pollutant.   I am inclined to
     believe that  it represents a physiological stress on the
     plant of which air pollution in the form of fluoride, sulfur
     dioxide, and possibly mineral salts,  is a contributing fac-
     tor  .... "6
     These preliminary investigations implicated  several pollu-
tants as probable contributors to the vegetation damage in Jack-
sonville in 1961.  Virtually no ambient air pollution samples
had been collected in the  Jacksonville area except the bi-weekly
particulate  samples for the Public Health Service's National
Air Sampling Network at  the State Board of Health Building
near downtown Jacksonville.  There were insufficient trained
personnel and specialized air pollution sampling devices avail-
able to governmental agencies operating in the Jacksonville
area to conduct the air sampling program necessary to adequate-
ly characterize the air quality of Jacksonville.

     Consequently, on  May 31, 1961, the State Health Officer,
Dr.  Wilson T. Sowder, requested technical assistance from the
Public Health Service  in a cooperative air quality study to be
conducted jointly by the Public Health Service,  the Florida
State Board of Health, and the Jacksonville City Health Depart-
ment.  In the latter part of July  1961, four members of the  Air
Pollution Training Staff and one of the Technical Assistance
Staff of the  Public Health Service, Division of Air Pollution,
were assigned to participate in this  study.

     The first objective was  to train local personnel in air pollu-
tion survey methods,  so that they could carry out future samp-
ling and analytical programs.  This was accomplished during
the initial phase  of the pilot study by a special short course in
survey techniques and subsequent on-the-job training during
the early part of the study.  The objectives of the pilot  study
were twofold:

-------
Introduction                                                  9


     1.   to develop a preliminary opinion as to whether the
city  of Jacksonville has a generalized air pollution problem.
     2.   to determine whether fluorides and sulfur dioxide
were present in the atmosphere in concentrations capable of
producing the damage to vegetation that had been experienced
in the Jacksonville-Duval County area.

     This report, therefore, describes the pilot study conducted
during August and September of 1961 in the Jacksonville-Duval
County area, including (1)  The emission inventory, conducted
concurrently with the sampling studies to determine the kind
and amount of pollutants emitted to the atmosphere in this area;
(2) an investigation of the meteorological conditions of the area;
(3) the short term intensive investigation conducted in Hemming
Park; and (4) the industrial area study of pollutants suspected
of causing  plant damage.
                                                     GPO 8O2-899—2

-------
         INVENTORY  OF  EMISSIONS
    To better evaluate existing and potential area-wide air
pollution problems in the Jacksonville area, an emission in-
ventory was carried out.  Approximately 50 of the largest
industrial and municipal sources of pollution and 200 commercial
establishments were contacted by personal visits,  question-
naires (see Appendix)  and/or telephone.  The information ob-
tained, plus the cumulative past experience of other investiga-
tors as published in the literature, provided a basis for a
reasonable estimate of pollution emissions.

    The classifications and types of sources, and  references
used to estimate these emissions are shown in Table 1.  Local
sources are defined as sources that are not uniformly distribu-
ted throughout the area.  As such,  these sources potentially
have the greatest effect on areas adjacent to them.  They also
influence the general community atmosphere,  especially under
certain meteorological conditions.   Area sources are those
sources that are distributed throughout the study area.  Classi-
fications of contaminants are listed in Table 2; the findings of
this study are summarized in tables in this section.

    The values  in this emission inventory are estimates and
should not be construed to be absolute.  For this reason, all
estimates have been rounded off to two significant  figures.
Equally important is the fact that the Tables do not include all
pollutants that are  emitted to the air over Jacksonville.  Esti-
mates were made  only for those classes of pollutants that have
been implicated as possibly having an adverse effect on man  or
his environment and for which emission factors  are available.
As further investigations are conducted in the field and new
findings are published, estimates such as those  contained in
this report would be listed for a far greater number of pollu-
tants .

ORGANIC GASES
Hydrocarbons

    It is estimated that 120 tons of hydrocarbons per day are
emitted to the air environment in the Jacksonville area (Table  3).
Approximately one-third of these emissions come  from trans-
portation sources.  In the Jacksonville area the  hydrocarbon
emission rate of approximately 1 ton per  square  mile per day
approaches the  rate estimated in Los Angeles.  '   Hydrocar-
bons and oxides of nitrogen in sufficient quantities can react  in
the presence of sunlight to form photochemical smog.   This

 ^Domestic heating estimates are based on the references indicated.
  Home heating requirements per housing  unit in the winter are
  estimated to be 80, 000 Btu per hour net  for a 16-hour day at an
  assumed central heating efficiency of 80% and an assumed non-
  central-heating efficiency of 50%.   Year-round hot water heating
  is estimated to be 100, 000 Btu per day gross.  Year-round
  heating for cooking is estimated to be  20, 000 Btu per day gross.
 cOn the basis of fuel tax figures and the number of heavy trucks
  registered in Duval County, it is estimated that 11% of the total
  vehicle miles are traveled by diesel-powered vehicles.  A fuel
  combustion rate of 8 gal/hour was  reported for  diesel-powered
  switch engines.

 Aldehydes,  Ketones and Other Organic Gases
     Estimated emissions  of aldehydes,  ketones and other organ-
 ic gases in the Jacksonville area are shown in Tables  4 and 5,
 respectively.  In both cases,  there is an expected increase in
 emission from summer to winter, resulting from the load im-
 posed on the air environment by domestic heating.

 (Table 6\.  It has been estimated that this amount Houble.s dur-
 ing the winter months because of domestic heating activities.
 Emission rates of oxides of nitrogen are comparable on a
 unit area basis to those of other communities experiencing
 photochemical smog. ^  As was the case in the estimated hydro-
 carbon emissions, these data indicate that Jacksonville has a
 potential photochemical smog problem.
 Oxides of Sulfur
     Estimated emissions of oxides of sulfur for the Jacksonville
 area are presented in Table 7.  During the summer months,
 240 tons of oxides of sulfur are emitted to the atmosphere per
 day.  Ninety-nine percent of these emissions are from local
 sources.  It is indicated that problems resulting from oxides of
 sulfur might occur in areas near 'these sources.

     During the winter months, it is estimated that emissions
 of oxides of sulfur increase to more than 400 tons per day.
 This expected increase is due to home heating activities.

 the daily emission of 360 tons is from transportation sources.
 Although the total amount emitted to the air is large, it is felt
 that carbon monoxide does not constitute an.area wide problem
 in the Jacksonville area.  Because the major source is the
 automobile,  however, problems might occur among individuals
 working in the environment immediately adjacent to main thor-
 oughfares.

 Carbon Dioxide
     Most investigators do not include carbon dioxide in their
 consideration of air pollution problems.  Certain researchers,
 however,  are concerned about the long range effect of this
 pollutant on man's environment. Plass  ..  in 1939,  stated that
 a relationship exists between the increase in carbon dioxide
 content of the atmosphere due to man's activities, and an in-
 crease in the annual average temperature of certain European
 cities. Kaplan*•', on the other  hand, has presented evidence
 that the increase in  carbon dioxide content  could only account
 for 10 percent of this annual increase in average  temperature.

-------
18
JACKSONVILLE AIR STUDY
What the long term effect of increasing carbon dioxide emissions
to the atmosphere will be, only time will tell.  Carbon dioxide
in combination with water vapor,  however, can cause the deteri-
oration of building materials such as limestone and also cause
the corrosion of magnesium. ^

     Estimated daily summer and winter emissions of  carbon
dioxide to the air  over the Jacksonville area  are  16, 000 and
31, 000 tons, respectively (Table  9).  All these emissions
result from combustion processes.   This  pollutant could be
used as an index of over-all combustion activities in the Jack-
sonville area.  Other investigators  have used carbon dioxide
in this manner. 19 Carbon dioxide concentrations over any city
would be much higher than any other pollutant, and, therefore,
easier to measure.

Hydrogen Sulfide

     Table  10 shows the estimated emissions of hydrogen sulfide

 day,  are a particularly troublesome cause of nuisance com-
 plaints,  since the pollutant is emitted near ground level.

     Sulfide-type damage to paints containing lead pigments and/
 or mercury-base fungicides has occurred in the Jacksonville
 area.  It can be presumed that emissions of hydrogen sulfide
 may cause an air pollution problem in this community.

 Hydrogen Fluoride
     It is estimated,  based largely on data provided by industrial
 representatives in the area,  that an average of 0. 06 tons per
 day of fluorides are  emitted annually from industrial processes.
 Because of variations in production rates, however, emissions
 on any given day may be  considerably more or less than the
 average. In the space heating season,  an additional 0.01 tons
 of fluorides are emitted per day from domestic sources (Table
 11).   It is doubtful whether the fluoride contribution of the area-.
 wide  domestic source constitutes an air pollution problem.  This
 inventory indicates that, the industrial process emission of 0. 06
 tons per day from local sources might be a problem in the vicin-
 ity of certain industrial operations.  This should be the subject
 of further study.

PARTICULATES

    Estimated daily emissions of particulates in the Jackson-
ville area are shown in Table  12.  Thirty tons are discharged
daily during the summer months; this increases to 48 tons per
day during the winter  season,  the increase being  due to domestic
heating activities.

    It is improbable that these amounts of particulates dis-
charged to the atmosphere would constitute a potential areawide
air pollution problem.  A potential nuisance problem might
exist, however, in areas close to the local sources listed in
Table 12.

INDICATIONS

stitute a real or potential problem in the Jacksonville area and
as such should be evaluated in greater detail.

        METEOROLOGICAL STUDIES
    Jacksonville,  Florida,  in general is quite well located topo-
graphically for the dispersion of waste material emitted to the
atmosphere.   There are no hills to act as barriers to air flow
over the terrain, or valleys to hold and concentrate pollutants
in the air.  Unfortunately, there are  other conditions in the area
conducive to  concentrating contaminants released to  the atmos-
phere.

    In the  southeastern portion of the United States,  it is not
unusual for large high pressure systems in the atmosphere to
move very slowly.  This causes  stable conditions near the
earth's surface and, frequently,  at some point above the ground
because of subsidence in the air  mass and radiational cooling
during the  hours of darkness.  Surface-based inversions in the
Jacksonville  area  occur throughout the year and are  generally
accompanied by light surface winds.  In addition, the industrial
area and the  principal business district of the city lie along the
west bank of  the St.  John's  River, which flows from  south to
north for approximately 4 miles.  At both ends  of this 4-mile
stretch,  the river makes a  90-degree turn.  The river and city
buildings have a direct influence on wind direction and speed in
this area.
    The dispersion of gaseous and fine-particulate wastes
emitted to  the atmosphere is associated with the height at
which they are released, wind speed  and direction, and the
stability condition of the atmosphere,  among other things.

    Good dispersion of any contaminant is favored by its re-
lease at high levels above ground, high wind speeds (with as-
sociated turbulence), and unstable conditions in the lower levels
of the atmosphere.  Even under such conditions, strong winds
may bring  some contaminants to ground level in relatively high
concentrations.  This would result from looping of the  stack
plume associated with turbulent air currents (gusty winds) de-
veloped in  the atmosphere because of surface obstructions and/
or changes in direction and speed of the wind.

     Poor dispersion of pollutants emitted to the atmosphere
occurs when stable air layers  (inversions) form either at the
ground or  within a few hundred feet above  the surface.  The
development of such stable  conditions in the lower levels pre-
vents vertical mixing of pollutants  and holds them within or
below these inversions.  Lowwind speeds  accompany such stable
conditions. In the Jacksonville area, conditions for  poor disper-
                              23

-------
24                                  JACKSONVILLE AIR STUDY
sion of contaminants frequently exist during all months of the
year.

     The following analyses of meteorological conditions  in the
 area establish the strong possibility that air pollution problems
 will intensify unless  some preventive action is taken.

 PAST STUDIES
     Climatic conditions for this area are summarized in the
 "Report on Florida's Air Resources. "  ^  This report includes
 the following information:

     1.  Long-term means of wind direction and speed.
     Z.  Annual percentage frequencies  of wind direction.
     3.  Sea and land breezes.
     4.  Percent frequency of inversions with base at 500 feet
 or below.
     5.  Frequency of atmospheric stagnation conducive to air
 pollution.
     6.  Frequency of thunderstorms.
     7.  Long-term means of annual number of days with fog
 and  cloudiness.
     8.  Frequency of occurrence of smoke.

     This information provides a background for consideration
 of the general problem of air pollution.  However, the micro-
 meteorological aspects of the  weather experienced in the Jack-
 sonville area vary considerably from the long-term means.

 METEOROLOGICAL CONDITIONS DURING THE PILOT STUDY

     The pilot study of the air  pollution  conditions existing in
 Jacksonville and its adjoining  industrial area raised  quite a
 problem concerning actual meteorological conditions for dis-
 persion of pollutants. Meteorological data were available from
 the U. S. Weather Bureau (USWB) at Imeson Airport approxi-
 mately 5. 5 miles  north of the  sampling area and from the U. S.
 Naval Air Station located approximately 7. 5  miles south  of the
 survey area.  Data from these stations were not too helpful,
 however, when considering dispersion of pollutants in the study
 area.

 Wind Speed and Direction

     Table  13 compares  the variances in wind speed and direc-
 tion as determined from official records at the two weather
 stations for the sampling period 0700,  September 5,  through
 0900,  September  13,  1961.  During the 195 hours of  sampling,
 the  USWB had 12  hours and the U. S. Naval Air Station 34 hours
 of winds from calm to 3 mph.   In general,  winds during the en-
 tire period were lighter at the Naval Air Station than at Imeson
 Airport.   When wind speeds were light at  either or both  stations

the indicated wind direction could vary by 180 degrees.  There
were 69 hours when wind directions differed by 45 degrees or
more.  When wind speeds reached 10 mph or greater at both
stations,  the wind directions recorded were the same  or, at
most, differed by one compass point (22 1/2 degrees).

     The wind instrument at the Imeson Airport station of the
USWB is  located about 52 feet above ground and at the U. S.
Naval Air Station about 30 feet.  Both stations  take their hourly
reading close to the end of the hour when direction and velocity
are determined from approximately a one- to two-minute ob-
servation.  The observations are comparable,  and the  difference
in height  may account for part of the higher velocity at the
USWB station.  In the study of dispersion of pollution in an area,
it is this  wind speed at the lower levels, however,  that is most
important.  Because the  data in Table 13 varys it is questionable
whether the wind data recorded at the above two  stations are in-
dicative of air flow over the industrial area studied.

     The U. S. Weather Bureau office at Imeson  Airport is the
official weather  station for this area; therefore,  the climatologi-
cal records for the period  October I960 through  September 1961
were used in this analysis-.  As expected, there are some var-
iances from the  long-term means  published in "Florida's Air
Resources. "^0  Table  14 summarizes hourly wind velocities
that occurred over the 12-month period.  Winds  were calm to
7 mph for 38 percent of the hours  during the year.  Wind speeds
of 7 mph  or less are conducive to  accumulation of emitted pollu-
tants, if a stable condition in the lower levels  of the atmosphere
exists.

Fog,  Smoke,  and Haze Observations

     Table 15 shows the number of days and hours during -which
fog, smoke, and haze occurred. The number  of hours of fog,
fog with smoke,  and smoke or haze conditions over the Jackson-
ville area indicate that long periods of stable atmospheric  con-
ditions  occur.
Cloud Ceiling and Visibility

     Other indicators of stable air conditions  are  cloud ceiling
and visibility. Cloud ceiling is the elevation  above ground of the
base of clouds at times when the degree of cloud cover is more
than 50 percent.   These data are also associated with the fog
conditions tabulated in Table 15.   Ceiling and visibility data were
broken down into three categories as  follows :

     1.   When cloud ceiling and visibility are  equal to   or
less than, 200 feet and 1/8 mile, respectively.

     2.   When cloud ceiling and visibility are  equal to,  or less

 indicate that during approximately 38 percent of the time stable
 conditions exist that would result in accumulation of pollution
 in the lower levels of the atmosphere.
 Inversion Frequency

     Climatological records from the National Weather Records
 Center, Asheville,  North Carolina,  give information as to the
 percent frequency of inversions to be expected at Jacksonville
 (Table 17).  The data are not entirely suitable,  however,  for
 determining probable periods favorable for accumulation of
 pollution; they were obtained from radio soundings taken at
 fixed times during the day--at either 0700 or 0800 and at 1900
 or 2000.  During the year, the hour of sunrise and sunset varies
 considerably between winter and summer.  The surface inver-
 sion,  with which air pollution at ground level is  closely associa-
 ted, generally breaks down shortly after sunrise and regenerates
 sometime during the evening between sunset and midnight when
 conditions are favorable.   Because of the time of the soundings,
 an erroneous opinion  might be developed as to -what one might
 expect regarding the actual percent frequency of inversions that
 developed during the year.  This factor is quite noticeable in

     The time at which stability develops was determined during
the period September 5-13,  1961,  when a resistance dynalog
temperature-differential recording instrument was being oper-
ated.  The lower element was 7 feet above ground and the upper
element 140 feet.  The 140-foot height was low enough to give
excellent micro stability data, yet was higher than all pollutant
sources except the two 250-foot stacks at the pulp mill in the
East Jacksonville industrial area.  Stability in the lower 140
feet of the atmosphere developed each night beginning between
2000 and 2300 and dissipated the following morning between
0700 and 0830 (Table 18).

     With reference to stability of the atmosphere, the term
 "lapse rate" is used frequently.  Lapse rate is defined as the
 rate of change of temperature upward through the atmosphere.
 If it is negative (temperature decreases with altitude) the air
 can be in either a neutral or an unstable condition; if positive
 (temperature increases with altitude),  the atmosphere is con-
 sidered to be in a stable condition conducive to accumulation
 of pollutants in the air.

     Table 18 gives the time of development and dissipation
 of ground inversions,  the time and maximum inversion lapse
 rate developed,  and the time and maximum lapse rate indicated
 during unstable conditions.  The data indicate a ground inver-
 sion occurs  almost nightly.  These inversions normally occur
 when winds are light and the sky is partly cloudy to  clear.

Precipitation

Precipitation occurred on an average of 12 days a month from
October I960 to September 1961.  Precipitation generally re-
duces the gaseous and particulate contaminants in the air, and
washes pollutants off  the surface of vegetation.  The importance
of precipitation as  a factor influencing pollution levels is  con-
sidered negligible,  however.

SUMMARY OF METEOROLOGICAL STUDIES
     The results of  the preceding observations are summarized
as follows:

     1.  Jacksonville has weather conditions throughout the
year that are conducive to accumulation of pollutants  emitted
to the atmosphere.

     2.  If dispersion of pollutants Irom particular sources is
to be studied,  a wind speed and direction recorder located
within the specific  study area will be necessary.  Also, an in-
strument to measure on a continuous basis or at frequent in-
tervals the lapse rate in the lowest few hundred feet would be
essential.  Meteorological data from the USWB station at Imeson
Airport and from the  Naval Air Station would be inadequate for
such detailed studies.

-------
         PILOT AIR  QUALITY STUDY
    In addition to providing field training for local personnel
in air pollution technology,  the main objectives of this pilot
study were:

    1.  To develop a preliminary opinion as to whether the city
of Jacksonville has a generalized  air pollution problem.

    2.  To determine -whether certain pollutants were present
in the atmosphere in concentrations capable of producing the
plant damage that had been experienced in the Jacksonville-
Duval County area.

    Two separate investigations were designed to meet these
objectives:  the  "urban investigation1' to determine whether
certain pollutants were present  in concentrations indicative of
a generalized air pollution problem,  and the "industrial area
investigation" to meet the second  objective.  These two inves-
tigations are discussed separately in this report, even though
certain phases of both were carried out concurrently by the
same personnel.
    The engineers  and chemists assigned to this study by the
Public Health Service,  State Board of Health,  and Jacksonville
Health Department comprised the  sampling team.  This group
planned and supervised the study,  calibrated and maintained
sampling equipment, standardized reagents,  performed the
detailed laboratory analyses,  and processed the data.  Sample
collection, transportation of samples to the laboratory, routine
laboratory analyses, and washing of  laboratory glassware was
handled by virtually the entire staff of sanitary inspectors of
the City Health Department.   During the second phase of the
study,  laboratory analyses, excepting those for fluorides, were
performed in the City Health Department's  stream pollution
laboratory by the City Sanitary Engineer and several of the
sanitary inspectors.

THE URBAN INVESTIGATION
    The urban investigation,  patterned after previous studies
                     71                         7 7
in Phoenix, Arizona,   and Washington, D. C. , " was con-
ducted at a downtown site from August 3 to  10, 1961.  The
site selected was the Hemming  Park bandstand located near the
center of the city business district (Figure 3).  The State Board
of Health's stream pollution laboratory trailer was located in
Hemming Park and served as the  survey headquarters and lab-
oratory during the  first phase of the  survey.   Table 19 summar-
izes the pollutants  sampled, the sampling and analytical methods

used, and the most common sources and effects of each pollu-
tant.  The sampling period and frequency for each pollutant
measured at the Hemming Park site are  listed in Table 20.
Because the morning concentration of pollutants after the over-
night buildup and the photochemical  reactions  of mid-day were
of chief concern in the urban study,  the Hemming Park samples
were collected every two hours from 0530 through 1430.
On Sunday, August 7, and Monday, August 8,  sampling was

 tions of all gases,  except carbon monoxide, were initially de-
 termined as  micrograms of contaminant per cubic meter of
 air sampled.  The concentrations in parts per million by volume
 (ppm) were calculated from these values.   For purposes  of this
 report, concentrations mentioned in the discussion of  results
 will be  stated as parts per million  by  volume for ease in com-

     None of the gaseous  sampling methods used were 100 per-
cent efficient.  Concentrations reported are in all cases less
than the true concentration in the original sample.  Any sample
obtained over a period of time gives an average concentration
for that time.  Actual pollutant concentrations existing at a
specific instant during the sampling period can be expected to
be greater and less than  those indicated by the sample.  There-
fore, in view of the fluctuating concentrations of the pollutants
measured,  and the expected efficiencies of the sampling equip-
ment,  concentrations reported for various pollutants are really
"minimum"  estimates of the  concentrations occurring during
the sampling period.

Sulfur Dioxide

     Concentrations of sulfur dioxide in 70 samples are sum-
marized in Table 22.  Sulfur dioxide concentrations ranged from
0. 0 to 0. 174, with a mean and median of 0. 015 and 0. 004 ppm,
respectively.  An arithmetic probability plot of the data is pre-
sented in Figure 4.  During this study 95 percent of the sulfur
dioxide concentrations were less than  0. 092 ppm.   Concentra-
tions reached maximum levels during  the night-time and early
morning hours (Table 21).  Although the concentrations of sul-
fur dioxide observed were generally low,  the  maximum concen-
tration (0. 174 ppm) during this non-heating period can be inter-
preted as a warning that  concentrations could exceed levels that
are known to cause damage to susceptible plants, 33 especially
during winter months when space heating is necessary.

Oxi dant s
     Concentrations of oxidants in 70 samples are summarized
in Table 22.  Oxidant concentration ranged from 0. 000 to 0. 162
ppm (as hydrogen peroxide), with a mean and median concen-
tration of 0. 052 and 0. 049, respectively; 95 percent of the ob-
servations were less than 0. 126 ppm.
     On 5 of the 8 days of this  study period,  the diurnal pattern
of oxidant concentrations indicated a photochemical type reac-
tion similar to those patterns  observed in Los Angeles, Cali-
fornia, 2^ Washington, D.  C. , 22  and Cincinnati, Ohio.27

Oxidant-Sulfur Dioxide Relationship
Because sunlight is associated with the formation of oxidants
in the  atmosphere, oxidant levels below 0. 05 ppm would be
expected during the predawn hours.  On 2 of the days,  however,
samples obtained at 0530 hours indicated oxidant concentrations
of 0. 077 and 0. 096 ppm.  A plot of oxidant and sulfur  dioxide
concentration on 3  of the days (August 6, 7,  and 8) is  shown in
Figure 5.   During the daylight hours, particularly on Monday,
August 7, the oxidant patterns indicate  a photochemical type

 reaction with high concentrations occurring when the sun is shin-
 ing brightest.  In general,  sulfur dioxide concentration patterns
 during the daylight hours are the reverse of the oxidant levels.
 Since  emission rates of sulfur dioxide during this study varied
 little with the time of day,  one would expect maximum concen-
 trations during the daytime when the ability of the atmosphere to
 diffuse pollutants would be  at its maximum.

     A relationship between oxidant levels and sulfur dioxide in
 the nighttime hours seems  to exist.  Non-daylight oxidant con-
 centrations  during  this period were  a maximum when sulfur
 dioxide concentrations  were a minimum. No quantitative com-
 parison can be made,  however, until a determination is  made

as to the quantitative interference of sulfur dioxide with this
particular sampling method for oxidants.   It is highly probable
that non-daylight oxidant concentrations are higher than indicated
by these data since the presence of sulfur dioxide in the air
sampled causes  measurements of oxidant to indicate lower
values than the actual concentration of oxidant in the air sampled.
Nitrogen Dioxide

     Nitrogen dioxide concentrations in 54 samples analyzed
ranged from 0. to 0. 05,  the mean and median being 0. 013 and
O.Oli ppm, respectively (Figure 6); 95 percent of the observa-
tions were less than 0. 028 ppm.
Carbon Monoxide

     As summarized in Table  22,  carbon monoxide concentra-
tions in 68 samples analyzed at the Hemming Park site and range
from 0. 3 to 25. 0 ppm, the mean and median being 2. 54 and 1. 50
ppm, respectively.  Ninety-five percent of the observations were
less than 8. 3 ppm.   The hourly data presented in  Table 21 indi-
cate that  carbon monoxide peak concentrations occur at hours
of the day when automobile traffic  would be expected to be at  a
maximum in this part of Jacksonville.  Quantitative comparison
of carbon monoxide concentrations with those observed in other
cities is not made as sampling sites are not comparable.  The
concentrations of this  pollutant appear  to be similar, however,
to those  reported in other cities in the  United States.

Airborne Particulates - Weight
     During this  period 24-hour hi-volume filtration samples
for  determination of total airborne particulate matter were ob-
tained.   Particulate loadings ranged from 50 to 105 micrograms
per cubic meter (Figure 7).  The  maximum concentration oc-
curred during the period starting  at 1600 hours on Tuesday,

Soiling Index
     The results of the 84 2-hour soiling index samples collected
from August 4 - August 11,  are shown in Figure 8.  The soiling
index is  expressed in Cohs per 1000 linear feet,  Values ranged
from 0 to a maximum of 2. 8 Cohs per 1000 Ft.  The results in
general indicate a considerable amount of soiling potential of
the airborne particulates.

 Soiling Index - Sulfur Dioxide Relationship

     On August 6,  7, 8,  and 9, the variations of concentration
 of these two pollutants with time were almost identical (Figure
 9).  This indicates that either meteorological conditions were
 such that the concentration of both pollutants varied in the same
 fashion or that both  pollutants came from the same source,
 or both. Concentration patterns of the other gases did not ex-
 hibit the same relationship with soiling index that seems to exist
 with sulfur dioxide.  Therefore, the sulfur  dioxide and the fine
 particles causing the soiling were probably from the same
 source or sources.

 Estimated and Measured Concentration

     Some of the estimates of pollutant emissions  presented
 earlier in this report have been used to calculate  estimated
 concentrations of certain pollutants in the air over Jackson-
 ville for three meteorological conditions.  The methodology
 used was similar to that of other  investigators. ^> 28', 29  .These

estimates are presented  in Table 23.  The calculated estimates
of pollutant concentrations are in the same general range
as concentrations measured during the urban investigation.
Estimates of atmospheric concentrations based on the emission
inventory, in this case, can be used to determine the minimum
air volume to be sampled in order to insure  collection of enough
pollutant for detection by available  analytical methods. ^9

THE INDUSTRIAL AREA INVESTIGATION
    Investigations of the extensive  plant damage that occurred
in the spring of 1961 implicated airborne fluoride and oxides
of sulfur as possible causes. 5, 6  The area involved centered
around the industrial zone bordering the St.  John's River.

 Therefore, the industrial area investigation was conducted in
 this area to determine whether or not the suspected pollutants
 were present in concentrations sufficient to cause damage to
 vegetation.  The investigation was divided into two parts: Phase
 I from August 4 to 12, and Phase II from September 5 to 13,
 1961.
     Six sampling sites were selected (Figure 10).  Station A
 was in the approximate geographic center of the area wherein
 vegetation damage had occurred.  Stations  B, C, D, and E -were
 located roughly 0. 75 miles north,  south, east,  and west of
 Station A.  Station F was  located between the two kraft pulp
 mills.

     Because vegetation damage was a major motivating force in
 the industrial area study, all samples were collected at a height
 of 36 inches above ground in order to measure the pollutants at
 the level where much of the observed vegetation damage had oc-
 curred.  Special tables were constructed by the  City Health De-
 partment to house the sampling equipment and meet this criter-
 ion (Figure 11).  Other criteria used in selecting the industrial
 area sampling sites were:

     1.  No site was selected at which a major air flow obstruc-
 tion projected higher  than 30 degrees above the horizon.

     2.  Electric power had to be available to operate  sampling
 equipment.   (The Jacksonville City Electric Department ran
 special power lines into four stations  to satisfy this criterion. )

     3.  Every unmanned site  had to be fenced to  protect against
 pilfering.  Only Station A was manned continuously.

     The pollutants sampled,  the sampling and  anlytical methods
 used, and the most common sources of these pollutants are
 listed in Table 24.

     The period of availability of the Public Health Service per-
 sonnel coincided with the annual non-operating period of both
 the major fluoride sources.  This permitted a  background
 fluoride level to be established, but necessitated a second sam-
 pling period in the industrial area to measure fluorides during
 normal operation of the two major  sources.  The first phase
 of the industrial investigation was conducted concurrently with
 the downtown investigation.

     Table 25 indicates the sampling frequency for each pollutant
 measured,  and the sampling sites.  Analyses for oxides of nitro-
 gen, sulfur dioxide,  and hydrogen sulfide  were carried out by

 Public Health Service.   The fluoride analysis, which involves
 a distillation procedure,  is most efficiently conducted in a
 laboratory geared to this work; hence all fluoride samples were
 shipped in polyethylene bottles to the Florida State Board of
 Health's Air Pollution Laboratory in Winter  Haven for analysis.

JACKSONVILLE AIR STUDY
     To compare methods of fluoride sampling,  one Greenberg-
Smith impinger and a sodium bicarbonate coated tube sampler
were operated in parallel at Station A for the entire 8 days of
the second phase of the industrial survey.  The tube sampler is
reported as  an efficient method of sampling gaseous fluorides. '
The Greenberg-Smith impinger collects both  gaseous and par-
ticulate fluorides.

     During  Phase I, neither fertilizer plant  was in production;
in Phase II,  both plants went on-stream.  A  comparison of the
results of Phase I and Phase II is indicative  of the effect  of
this specific type of industrial activity on pollution levels in
the area.

Fluorides

     During Phase  I, 117 8-hour impinger samples were ob-
tained in the industrial area;  120 samples were collected during
Phase II.  The summary of results is listed in Table 26.  In-
dividual results for Phase II are presented in Table 27.

     To determine the fraction of the total airborne fluoride
 that was  gaseous and that which was particulate a sodium bi-
 carbonate coated tube sampler^ was operated at Station A for
 the full period of Phase II.  The "gaseous"  sampler indicated
 an average fluoride concentration of 2. 10 micrograms per cubic
 meter.  A comparison with the average concentration of total
 fluorides for this period at Station A indicates that about half
 of the airborne fluorides were in the gaseous state.

    It is concluded from these data that fluoride  concentrations,
at Station A at least, were high enough to cause damage to sen-
sitive vegetation under proper growing conditions.
    The data shown in Table  27 were analyzed as to frequency
of occurrence of maximum,  second highest, and  minimum con-
centrations  at each station during each run.  The results of this
analysis are shown in Table 28.  In 20 of the 24 runs during

Phase II,  samples from Station A indicated the highest concen-
tration.  Stations D and E indicated maximum concentration
on 1 and 3 of the runs,  respectively.  During the three runs in
which Station A was  second highest,  Stations D and E indicated
maximum concentrations.  Although the maximum concentra-
tions observed during these runs were not the maximum con-
centrations  observed during the 24 runs at Stations D and E,
during Phase II transport conditions were such as to produce
maximum concentrations at site D and across the St.  John's
River at site E at certain times.  This occurred on September
5, 6, and 7,  which -were  not times of maximum production
of fluorides during this phase.  It can, therefore, be  concluded
that at times of full plant production, with meteorological  con-
ditions similar to those that produced the maximum series
concentrations at Station  D and E,  concentrations of fluorides
much higher than those observed in this study can be  expected to
occur at Stations D and E.  Figures  1 and 2 graphically show
wind movements from the northwest transporting pollutants
across the river from Jacksonville.  Figures 13  and 14, taken
one hour apart during Phase I, demonstrate variability of  wind
movement within a very limited time.

 deposition occurred at Station A,  where 2. 27 micrograms per

 deposition in the rain gage at Station A  during the  same period
 was 0. 133 micrograms per square  centimeter.  These results
 indicate that approximately 6 percent of the material deposited
 in the dustfall jar was contributed by rainout.  The ratio of the
 soluble to insoluble fluoride fraction of each sample has been
 included in Table  30.

 Sulfur Dioxide^
      During Phase I and II,  498 analyses for sulfur dioxide were
 performed on samples taken at sites A, B, and C.  These three
 stations are  situated  in a general north-south orientation, as
 are the main sources of sulfur dioxide in this area — the power
 plants and the fertilizer industry (Figure  10).   During  Phase I,
 only the power plants were in operation.  Table 31 summarizes
 results of both phases.
      During Phase I,  maximum sulfur dioxide concentrations
 were 360, 240  and 210 micrograms per cubic meter (0. 137,
 0. 092 and 0.  079 ppm) for Stations C, A, and B, respectively;
 during Phase II, they were 260,  140 and 97 micrograms per
 cubic meter  (0. 099, 0. 054 and 0. 037 ppm) for  Stations  A, B,
 and C, respectively.
     In comparing the concentrations exceeded by 5 percent of
 the observations for each station in the  two phases, it is  seen

that this value for Stations B and C decreased from Phase I to
Phase II, while it increased for Station A.  This  increase at
Station A from 52 micrograms per cubic meter (0. 020 ppm)
to 140 micrograms per cubic meter (0. 053 ppm)  may be an
indication of the effect of the fertilizer industry's sulfuric
acid plants on the environment.  (These plants were inopera-
tive during Phase I. )

     The data collected at Station A during Phase I and II  are
presented on arithmetic probability paper in Figures 15 and
16, respectively. With the exception of the maximum value ob-
tained during Phase I,  Figure 15 exhibits a pattern of two
statistically normal distributions superimposed on each other.

Figure 16, however,  exhibits a pattern of three normal dis-
tributions.  These patterns could have been due to the influence
of wind direction  on transport of pollution from source to sam-
pling site.  During Phase I, the pattern might have been a re-
sult of east-west,  and north-south wind movement; Phase II1 s
pattern might have resulted from a western,  north-south and
easterly movement of air.   The higher concentrations probably
occurred with an  easterly wind direction as the sampling site
was located in a westerly direction from the sulfuric acid plants
operating during Phase II.

tions are shown in Table 32.  The hypothesis mentioned above
seems to be borne out by this analysis.  The results indicate
that this type  of analysis would produce more conclusive results
if more appropriate meteorological measurements were made
in the area under study, because of the variables involved.
Nitrogen Dioxide

     During  Phase II,  97 analyses for nitrogen dioxide were made
on samples  collected at Station A.  The distribution of results is
shown in Figure  17.  Concentrations ranged from 0 to 300 micro-
grams per cubic meter (0.  159 ppm), the median concentration
being 27 micrograms  per cubic meter (0. 014 ppm). The first

half of this distribution is very similar to that observed during
Phase I at the Hemming Park Site (Figure  6); the s-econd half
consists of higher concentrations, which may be indicative of
the nitrogen dioxide contributed by the industrial activity in
this area.  Further study of this pollutant has to be carried out
concurrently -with a detailed micrometeorological study before
this indication can be proven.

Hydrogen Sulfide

    During Phases I and II, 576 2-hour lead acetate'-impreg-
nated tape samples were obtained at Stations B, C,  and F for
determination of hydrogen sulfide.  The results are summar-
ized in Table 33.  Some doubt exists as to  whether the  concen-
trations indicated by these samples are quantitative. At  nu-
merous times, the odor of hydrogen sulfide was observed at
these stations.  The accepted odor threshold for this pollutant

is 0. 025 to 0.10 ppm.  In view of this, no interpretation of
these data has been made.  It is apparent from the data, how-
ever, that hydrogen sulfide was present during this study.  It
is suggested that in future studies of this pollutant, parallel
sampling should be conducted with a tape sampler and the
bubbler-type collector method suggested by Bender and Jacobs.34

     OF AIR POLLUTION IN JACKSONVILLE,  FLORIDA.   PHS
     Publ.  No. 999-AP-3.  1963.  65 pp.

ABSTRACT:  The objectives of this pilot study were to develop
     a preliminary evaluation of air pollution in Jacksonville
     and to determine whether fluoride and sulfur dioxide con-
     centrations were sufficient to cause damage to vegetation
     that had occurred in the area.  The study consisted of an
     emission inventory,  a. meteorological investigation, an
     intensive short-term study of downtown Jacksonville,  and
     an industrial area  study.  Pollutants  sampled for included
     sulfur dioxide,  oxidants, nitrogen dioxide,  carbon monox-
     ide, hydrogen sulfide,  fluorides, and suspended particu-
     lates.   During the  study fluoride concentrations were high
     enough in certain parts of the city to  cause damage to sen-
     sitive  plants; sulfur dioxide and oxidants were also present
     at significant levels.  Results of the study also indicated
     that photochemical smog is  produced over Jacksonville,
     that pollutants from Jacksonville are transported across
     the St.  John's  River,  and finally, that several pollutants
     constitute a potential problem in the city and should be
     evaluated further.
