       As the concern for air quality grows, so does the con-

cern over the less ubiquitous but potentially harmful contami-

nants that are in our atmosphere.  Thirty such pollutants have

been identified, and available information has been summarized

in a series of reports describing their sources, distribution,

effects, and control technology for their abatement.

       A total of 27 reports have been prepared covering the

30 pollutants.  These reports were developed under contract

for the National Air Pollution Control Administration  (NAPCA) by

Litton Systems, Inc.  The complete listing is as follows:


    Aeroallergens (pollens)       Ethylene
    Aldehydes (includes acrolein  Hydrochloric Acid
      and formaldehyde)           Hydrogen Sulfide
    Ammonia                       Iron and Its Compounds
    Arsenic and Its Compounds     Manganese and Its Compounds
    Asbestos                      Mercury and Its Compounds
    Barium and Its Compounds      Nickel and Its Compounds
    Beryllium and Its Compounds   Odorous Compounds
    Biological Aerosols           Organic Carcinogens
      (microorganisms)            Pesticides
    Boron and Its Compounds       Phosphorus and Its Compounds
    Cadmium and Its Compounds     Radioactive Substances
    Chlorine Gas                  Selenium and Its Compounds
    Chromium and Its Compounds    Vanadium and Its Compounds
      (includes chromic acid)     Zinc and Its Compounds


       These reports represent current state-of-the-art

literature reviews supplemented by discussions with selected

knowledgeable individuals both within and outside the Federal

Government.  They do not however presume to be a synthesis of

available information but rather a summary without an attempt

to interpret or reconcile conflicting data.  The reports are
                            iii

-------
necessarily limited in their discussion of health effects for

some pollutants to descriptions of occupational health expo-

sures and animal laboratory studies since only a few epidemic-

logic studies were available.

       Initially these reports were generally intended as

internal documents within NAPCA to provide a basis for sound

decision-making on program guidance for future research

activities and to allow ranking of future activities relating

to the development of criteria and control technology docu-

ments .  However, it is apparent that these reports may also

be of significant value to many others in air pollution control,

such as State or local air pollution control officials, as a

library of information on which to base informed decisions on

pollutants to be controlled in their geographic areas.  Addi-

tionally, these reports may stimulate scientific investigators

to pursue research in needed areas.  They also provide for the

interested citizen readily available information about a given

pollutant.  Therefore, they are being given wide distribution

with the assumption that they will be used with full knowledge

of their value and limitations.

       This series of reports was compiled and prepared by the

Litton personnel listed below:

                         ABSTRACT

     Ammonia is a natural constituent of the atmosphere but

exists in concentrations below the level which is hazardous

to humans, animals, plants, or materials.  High concentra-

tions of ammonia gas are corrosive to mucous membranes; can

cause damage to the eye, throat, and upper respiratory tract;

and can produce residual damage and even death in humans and

animals.  High concentrations are also toxic to most plant

life and have corrosive effects on materials.

     Almost all of the ammonia in the atmosphere is produced

by natural biological processes, largely from the decomposi-

tion of organic waste material.  Man contributes a compara-

tively small portion of ammonia to the atmosphere, mainly

through combustion and industrial processes involved in the

production or use of ammonia.

     Air quality standards for ammonia concentrations have

not been established in the United States.  Measurements of

environmental concentrations indicate average levels of
                     3
approximately 20 |_ig/m •

     Wet scrubbers, bag filters, and charcoal filters are

used to control industrial losses of ammonia to the atmosphere.

The economic value of ammonia encourages its conservation in

commercial processes.  No economic data are available on

damages caused by ammonia pollution.

     Adequate methods are available for the detection and

measurement of ammonia in the atmosphere.

1.   INTRODUCTION



         The main source of atmospheric ammonia is naturally-



    produced ammonia which is released from land and ocean areas.



    In terms of total air content of ammonia,  urban-produced



    ammonia is of lesser importance, though it may be important



    from the air pollution standpoint in localized situations.



         The primary source of ammonia air pollution in cities



    is the combustion process involved in the combustion of fuels,



    incineration of wastes, and use of the internal combustion



    engine.  Industrial sources emitting ammonia are chemical



    plants, coke ovens, and refineries.  Other sources are stock-



    yards and similar installations, where ammonia is formed by



    biological degradation.

-------
2.   EFFECTS
    2.1  Effects on Humans
         Ammonia gas, if inhaled, affects mainly the upper res-
    piratory tract, according to Jacobs.30  Only a small percen-
    tage of an inhaled dose reaches the lungs at the inhaled
    concentration.  At high concentrations (1,700,000 ug/m  to
    4,500,000 (ag/m ), ammonia acts as an asphyxiant.  At concen-
                            3                "3
    trations of 280,000 ug/m  to 490,000 |ag/m  the gas can produce
    eye, nose, and throat irritation.
                         62
         Silverman et al.   exposed seven adult males to ammonia
    gas concentrations of 350,000 |jg/m .  Significant effects on
    respiration resulted, as well as irritations of the throat
    and nose and hypoesthesia.
               07
         Kustou   ran 7-to-8-hour tests to determine the effect
    of ammonia on certain physiological and biological indexes
    in man.  He found that at concentrations of 13,000 |_ig/m3 the
    urea and ammonia content of the blood and the urine increased.
    In addition, he noted a lowering of the oxygen use factor
    and some respiratory depression.
         In 1955 Hemeon^  suggested that zinc ammonium sulfate
    aerosols were in part responsible for the irritant effects
    of the air during the Donora Smog Episode in 1948.  Amdur
            4
    and Corn  found that aerosols of zinc sulfate, zinc ammonium
    sulfate, and ammonium sulfate produced severe irritation in
    guinea pigs.  The double salt was the most irritative.  They
    established that the smaller the particles, the greater the

-------
irritative action and that the aerosols, in conjunction with



sulfur dioxide gas, produced synergistic effects.  This



synergistic effect was particularly enhanced when the ammo-



nium sulfate and zinc ammonium sulfate were combined with


sulfur dioxide gas.



2.2  Effects on Animals



2.2.1  Commercial and Domestic Animals



     No reports were found on effects of ammonia on livestock,



although they can be expected to be negligible at the low



concentration normally found in urban or rural atmospheres.



High localized concentrations due to accidental releases of



ammonia could cause significant effects.



2.2.2  Experimental Animals



     Several studies have been made on the effects on experi-



mental animals both of ammonia alone and of ammonia and carbon


                     7fi
combinations.  Weedon   reported that guinea pigs and rabbits



exposed to 1,740,000 |jg/m  of ammonia developed acute and



chronic lung lesions.  The rabbits were less sensitive than



the guinea pigs, which tolerated around 1,000,000 |_ig/m3.



When Weedon   exposed house flies to ammonia concentrations

               3
of 700,000 i_ig/m , 6 percent of the flies were killed in 16

                                                     •3

hours.  He also exposed mice and rats to 700,000 |_ig/m  of



ammonia for 16 hours.  Two older animals showed some evidence



of slight dyspnea.  At the end of the exposure, the eyes of



all the rats and mice were bright, with little or no evidence



of lacrimation.  The gross findings at autopsy for one rat

-------
 (considered typical of the exposed group),  which died 12

 hours after exposure are shown in Table 1.

      Weatherby   exposed guinea pigs to 118,000 |ig/m  of

 ammonia and found mild changes in kidneys,  spleen,  adrenals,

 and liver in 18 weeks.  No change was found in 12 weeks.

           13
 J.  Dalhamn   found that low concentrations  of ammonia (2,000
      )  caused the cilia of the upper respiratory tract of rats
                                            pQ
 to stop beating in 8 to 9 minutes.   Friberg   found that the

 process of arresting the cilia was  reversible until concentra-

 tions around 210,000 lag/m3 of inhaled air were reached.

-------
                           14                            •}
     T. Dalhamn and L. Reid   exposed rats to 70,000 ng/m° of



ammonia and 7,000 |_ig/m  of pulverized carbon in air for 6



months.  The severe mucosal damage and impairment of ciliary



activity observed suggested a synergistic effect.



2.3  Effects on Plants



     Thornton   exposed tomato plants, buckwheat, and tobacco



plants to air concentrations of ammonia of 700; 2,800; 1,000;



44,000; 175,000; and 700,000 |_ig/m3 in air for periods of



1, 4, 15, 60, and 240 minutes.  He found that ammonia at



700,000 |ag/m3 caused changes in the pH of tomato plant leaf



and stem tissue but did not cause damage at lower concentra-



tions.  He also found that there was some correlation between



pH change and observed injury.  The time required to produce



injury to 50 percent of the exposed plant surfaces at 700,000



|jg/m  is shown in Table 2.  In general, acute injury due to



ammonia is shown by a collapse of tissue without subsequent



loss of chlorophyll.  Definite injury was observed on buck-



wheat, coleus, sunflower, and tomato after exposure to 38,000



p.g/m  of ammonia for about 1 hour; slight injury was observed



at 11,500 |_ig/m3 after 4 hours; and at 5,600 lag/m3, the plants



were either uninjured or slightly marked after 5 hours.  Nearly



all parts of the leaf had a cooked green appearance which



became brown upon drying.^7*64,69-71


             73
     Treshaw   indicated that ammonia can induce glazing and



silvering, particularly of lower leaf surfaces of vegetables.

     Benedict and Breen  fumigated 10 species of common weeds


which occur throughout the United States in an effort to

develop a method for identifying pollutants causing damage.

The ammonia produced spots of cell collapse and death, primar-

ily along the margins of the leaves.  With grasses, small spots

developed over the area where the leaf bends, giving a powdery

appearance.  The powdery marking increased in the region be-

tween the bend and the tip as the intensity of fumigation was


increased.  Table 3 shows the percentage of leaf area marked
                                          <3               o

reduced.  An extension of the treatment period to 960 minutes



killed all of the seeds.  A 1-minute exposure had no retarding



effect.  The germination of seeds treated in the dry state was



delayed by 240 minutes' exposure.



     Rye seeds were more sensitive to ammonia than those of



radish.  Exposures of soaked seeds to 700,000 |_ig/m  for as long



as 240 minutes resulted in 100-percent kill, while those


                       o

exposed to 175,000 |_ig/m  for 960 minutes had a germination



rate of only 48 percent.



     Classes of organisms differ in their sensitivity to



ammonia gas.  Leaves are the most sensitive, followed by stems,



fungi, and bacteria, which are intermediately sensitive.

Seeds are least sensitive of all to the gas.



2.4  Effects on Materials



     Ammonia associated with sulfur dioxide and moisture can



cause crystalline bloom defects on the surface of varnish and

paints, according to Holbrow.    In another study, Preston



exposed various metallic surfaces to fine powders in atmospheres



of varying humidities.  The character of the resulting corro-



sion was filiform, typical of highly reactive particles in the



atmosphere.  Ammonia can also discolor some fabric dyes.



2.5  Environmental Air Standards



     The American Conference of Governmental Industrial



Hygienists at their 29th Annual Meeting in 1967 recommended



an occupational threshold limit for ammonia in air of 35,000



|j.g/m .  The Bureau of Medicine and Surgery, Department of the

-------
Navy, has recommended an ammonia threshold limit for 1 hour


of 280,000 |J.g/m  .    The permissible limit for ammonia in a


submarine during a 60-day dive is around 18,000 i_ig/m .    No


ambient air quality standards for ammonia exist for the


United States.  However, such ambient air standards exist for


Czechoslovakia, the U.S.S.R., and Ontario, Canada, as shown in


Table 5.

3.   SOURCES




         The major portion of atmospheric ammonia is produced by



    biological processes in land and sea masses,  and the gas then



    escapes into the atmosphere.    Ammonia produced by industry



    and as a result of urban activities, though of lesser impor-



    tance, may nevertheless be a factor in air pollution in



    localized areas.  The major source of urban-produced ammonia



    is the combustion process which occurs in operation of the



    internal combustion engine, combustion of fuels for heating,



    and the incineration of wastes.  Industrial sources of ammonia



    are refineries, fertilizer plants, and organic chemical process



    plants.  Other minor sources of ammonia arise from biological



    degradation in areas where animals are kept,  such as stoclc-



    yards, and from miscellaneous uses of ammonia in cleaning



    both in industry and in the home.



    3.1  Natural Occurrence


                                         9!         9
         According to Frost and Sullivan,   3.7 x 10  tons of



    ammonia are released into the atmosphere annually.  Of this

                         fi

    amount, only 4.2 x 10  tons are emitted to the atmosphere as



    a result of industrial and urban processes; therefore,



    roughly 99.9 percent of the atmosphere's ammonia concentration


                                                       32
    is produced by natural biological processes.   Junge   indicates




    that the main biological source of ammonia is the decomposition



    of organic waste material.  Approximately 1.0 g of ammonia per



    man per day is produced metabolically.    Ammonia is given



    off from manure in piggeries   and other installations where

-------
                                                          11
animals are kept.  Ammonia is also generated during treat-



ment of waste water in sewage plants.    No information was



found on the quantity of these emissions.  Ammonia is also



found in sea water and in volcanic gases.



3.2  Production Sources



     Ammonia is produced commercially in chemical process



plants, as a by-product in the manufacture of other chemicals,



mainly in making coke from coal, and as a product of combus-



tion, refining of oils, and other processes.



3.2.1  Haber-Bosch Process



     The Haber-Bosch process for the production of ammonia



accounts for over 85 percent of the total commercial yield.



This process involves the combining of hydrogen and nitrogen



gases in the presence of a catalyst.  The hydrogen is usually



obtained from water gas (a mixture of carbon monoxide and



hydrogen), and the nitrogen is obtained from the air.  Hydro-



gen and nitrogen are combined with the catalyst in the ammonia



generator to form ammonia when heated to temperatures of



450 to 600°C under pressure of 200-1,000 atmospheres.



     The world's production of ammonia in 1965 was 26.8



million tons, and this is expected to reach 70 million tons



by 1970.77  In the U.S.A., 7.8 million tons of ammonia were



produced in 1964.  By 1968 this had increased to 17.25


             fift
million tons.    The 1968 ammonia production rates by States



are shown in Table 6.

-------
                                                          12
     In 1962, there were 64 synthetic ammonia plants in this
country, while in 1964 there were 95.  By 1966 this number
had increased to 109.

3.2.2  Coke Plants
     In a report on Russian coke ovens, Kapitulskii"'^ states
that the usual ammonia concentration in air samples at the
top of a coke oven during charging was 6,300 to 8,000 tag/in  .
This was reduced to 3,500 to 4,400 |ag/m3 by smokeless charging-
that is, diverting the coke-oven gas by vacuum to the gas-
collection main.  No data were found on ammonia emissions
from coke-oven plants in the United States.

-------
                                                         13
     In 1966 about 66 million tons of coke were produced per

year in this country in 66 coke-oven plants.   The value of

the coke at the coke oven was estimated to be $1,144 million.

The production rate of coke from 1957 to 1968 is shown in

Table 7.

3.2.3  Oil Refineries

     The main source of ammonia in oil refineries is from the

catalyst regenerators in the catalytic cracking plants.  The

ammonia releases from oil refineries are given in Table 8.

At the time the data were  compiled, there were 18 refineries

in the Los Angeles area with a combined  capacity of 700,000

barrels of crude oil per day.

     In 1960 there were approximately 300 oil refineries dis-

tributed throughout the U.S.A.  The catalytic cracking capa-

city of these refineries was 3.7 million barrels per day of

fresh feed plus 1.1 million barrels per day of recycle.

By 1968 there were around 270 refineries in the U.S.A., with

a catalytic cracking capacity of 4.1 million barrels per day

3.2.5  Combustion Processes


     Ammonia is produced as a result of combustion, mainly


from the use of fossil fuels and incineration of waste materi-


als.  These sources generally result in direct emission of


the ammonia into the atmosphere.


     The emission of ammonia from internal combustion engines


has been estimated at 2.0 lb/1,000 gallons burned for gasoline

                                       O £^
enginesH/26/43 an(j for aiesei engines.    The total ammonia


emitted daily into the atmosphere of Los Angeles from the


combustion of gasoline in 1953 was estimated at 5.0 tons a


day.  The rates of emissions of ammonia from various categories


of fossil fuels is presented in Table 10.

       The emission of ammonia from  incineration of solid



wastes is shown in Table 14 in the Appendix.  The total



ammonia emitted from domestic and industrial solid waste



disposal that might be expected from a metropolitan area of



100,000 population, using several methods of disposal, is



shown in Table 15 in the Appendix.



       The United States produces at the present time about



170 million tons of refuse per year, of which about 15



percent is incinerated.   In 1980, about 260 million tons per



year of refuse will be produced, and the percentage to be



incinerated is expected to increase  about 50 percent.  The

expenditure for incinerators in 1966 was 50 million dollars.



This figure is expected to rise to 100 million dollars by



1980.21



3.3  Product Sources



     Ammonia is used as a raw material in the production of



nitric acid, fertilizers, and the syntheses of hundreds of



organic compounds, including many drugs, plastics, and dyes.



Approximately 85 percent of the ammonia is used as anhydrous



ammonia fertilizer or as a raw material for other fertilizer



production.



     Very little information is available on ammonia emissions



from these plants.  It has been reported that 2,600 tons of



ammonia per year are released from a fertilizer plant in



South Point, Ohio.28  Another reference reported that 0.078



tons of ammonia are released for each plant consuming 109

     Burakhovitch made air pollution surveys in the vicinities



of chemical plant complexes in Russia.  The plants involved



produced mineral fertilizers, synthetic monomers, ammonia



alcohols, plastics, and nitric acid.  Sampling sites were



situated at 2,000 and 4,000 meters from the principal dis-



charge sources.  The ammonia concentrations measured showed



a significant reduction of ammonia pollution between 1963 and



1964, attributable to the construction of waste-gas absorbers



in the nitric acid plant and improvement in ammonia manufac-



turing technology by the changeover to natural gas.

     In dilute solutions ammonia is used domestically, com-

mercially, and industrially as a cleansing agent.  Ammonia

is also used in developing drawing reproductions.  Table 12

shows the emissions of ammonia when used for cleaning machinery

and developing reproductions of drawings.

in urban areas is approximately 20 |jg/m3.  '  '    The back-

ground concentration of ammonium in the lower troposphere is

            3                                  3
about 6 |ag/m  in the mid-latitudes and 140 ng/m  near the

        59
equator.    Data on atmospheric concentrations of ammonium

for various cities of the United States are presented in

Tables 16 and 17 in the Appendix.

4.  ABATEMENT



         No information has been found on the abatement of ammonia



    as such in air pollution; however, methods used to abate other



    pollutants with which it is associated also reduce the quan-



    tity of ammonia that reaches the atmosphere.  For example,  in



    smokeless charging of coke ovens (that is, collecting the



    bulk of escaping coke-oven gas, coal dust, and tar by vacuum



    during coke-oven charging), the ammonia emissions to the


                               34
    atmosphere are cut in half.



         In incineration systems where wet scrubbers are used to



    remove fly ash, the ammonia in the gas stream leaving the



    incinerator should also be reduced.  However, no information



    was found on this subject.



         In the chemical industry, where ammonia is used as a raw



    material, its recovery is a matter of fundamental economic



    importance; methods have .therefore been designed to minimize



    its loss.  For high concentrations of ammonia, gas wet scrub-



    bers can be used.  For ammonia concentrations in air between



    approximately 16 to 27 percent (flammable range)->° the gas



    can be flared.  Impregnated activated charcoal has been used



    to remove ammonia from the air in laboratories that use



    animals in research and in other places where animals are


                          40
    kept in large numbers.    Where the ammonia occurs as a



    solid—as ammonium sulfate in the fertilizer industry for



    instance—conventional methods for solids removal can be used



    such as bag filters, electrostatic precipitators, and wet



    scrubbers.

5.   ECONOMICS



         In the future, greater emissions of ammonia to the



    atmosphere may be expected as a result of increases in incin-



    eration, fuel oil usage, catalytic cracking,  and gasoline



    consumption.  These added emissions should be offset by the



    growing number of improved abatement systems  installed prin-



    cipally to reduce emission of other substances,  such as



    particulates, hydrocarbons, and sulfur dioxide.   However, no



    information has been found on the effectiveness  of these sys-



    tems in removing ammonia, or on the number of abatement



    systems to be installed.



         The economic impact of ammonia pollution on humans, plants,




    and animals is expected to be minimal since at normal atmo-



    spheric concentrations the ammonia will have  little or no



    deleterious effect.  Localized accidental emissions of ammonia



    in high concentrations could have serious economic impact



    resulting from death or sickness of animals or humans and



    damage to plants.  No information has been found on the eco-



    nomic costs of ammonia air pollution or on the costs of its



    abatement.



         Data on production and consumption of ammonia are pre-



    sented in Section 3.

6.  METHODS OF ANALYSIS


         The primary method used in air pollution for analyzing


    for ammonia in air is the Nessler colorimetric method.   '2/


    The sample is collected by passing the air through a standard


    impinger containing 0.1N sulfuric acid.  The collected sample


    is then contacted with Nessler's reagent and examined in a


    colorimeter.  If a cloudy solution forms after the addition


    of Nessler's reagent, alkaline Rochelle salt is added to clear

          9Q
    it up.^y


         To obtain more accurate results prior to Nesslerization,


    the acidic sample may be made alkaline and the ammonia dis-

                                                         7
    txlled into a receiver containing .02N sulfuric acid.


    Nessler1s reagent is then added, and the sample is analyzed


    colorimetrically.  The Nessler colorimetric method of analysis


    gives the total ammonia content of the air:  i.e., both


    gaseous and particulate components.  Equipment based on Nessler's

                                                     2
    method has been developed for automatic analysis.


         Another method utilized for analyzing for ammonia is the


    indophenol blue technique.  The sample is collected as out-


    lined above.  It is then contacted with alkaline phenol and


    sodium hypochlorite, which turns it blue-green.  The sample

                                \
    color is then read on a colorimeter.  The ammonia determined


    is the total ammonia and ammonium in the sample.  This method


    was developed for controlled atmosphere applications but can


    be applied to air pollution work.  The indophenol blue tech-


    nique has also been adapted for use in automatic ammonia

              35
    analyzers.

     Smolczyk   showed that paper impregnated with phenol-



phthalein will change color in air in the presence of 10 to


                          Q                           ^fi
100 ppm (7,000-70,000 |jg/mj) of ammonia gas.  Korenman



used impregnated diazotized alpha or beta-naphthylamine to



test for ammonia.



     Canibi   indicated that ammonia samples with as little

                   o
as 0.01 ppm (7 |_ig/m ) ammonia can be analyzed by titrating



directly with standard solutions of sodium hydroxide and



sulfuric acid.  In addition, industrial methods based on


                                             42
infrared analysis and colorimetric techniques   are used



for ammonia analysis.
