Acrylonitrile

The primary exposure to acrylonitrile appears to be occupational, via the inhalation pathway. Acrylonitrile is primarily used in the manufacture of acrylic and modacrylic fibers. It is also used as a raw material in the manufacture of plastics, adiponitrile, acrylamide, and nitrile rubbers and barrier resins. Exposure to acrylonitrile in the air you breathe or the water you drink is unlikely when your place of living is not near a factory where acrylonitrile is made or near a hazardous waste site that contains acrylonitrile.

Arsenic Compounds

Arsenic emissions are primarily from burning of fuels and wastes from area and mobile sources, although background levels are significant. It is an element that is widely distributed in the earth’s crust, and is released by volcanoes and mineral weathering. It is also emitted from commercial and industrial processes, including smelting of mineral ores.

Chloroform

Chloroform does not react quickly in the atmosphere, so there are
significant residual levels from emissions around the world that
are represented in NATA as background concentrations.

In New Jersey, there are also point sources dominating the predicted
air concentrations in a few counties. The USEPA NATA estimate of
point source emissions in Warren County was fourteen (14) times
higher than Toxic Release Inventory (TRI) reported emissions.

Cobalt

Cobalt is a naturally-occurring element that is used to make superalloys, pigments, catalysts, and lithium or nickel-cadmium batteries. It is emitted into the air primarily from fossil fuel and waste combustion; vehicular and aircraft exhaust; processing of alloys; copper and nickel smelting and refining; and the manufacture and use of cobalt chemicals and fertilizers.

The primary source of diesel particulate matter is non-road mobile
sources.

Ethylbenzene

Ethylbenzene is emitted primarily from gasoline engines. It is naturally found in coal tar, petroleum and in manufactured products such as inks, pesticides, and paints. It is used to make other chemicals such as styrene, and in solvents and fuels.

Ethylene Dibromide

Emissions of ethylene dibromide are rare. However, significant
quantities of ethylene dibromide remain in the air due to its long
half-life. This residual level is represented in NATA as a background
concentrations. The primary source of ethylene dibromide emissions
is almost exclusively background.

Ethylene Oxide

The primary source of ethylene oxide emissions is area sources, primarily commercial and hospital sterilizers. It is also used as a chemical intermediate in manufacturing. A significant amount is now attributable to background concentrations. For additional information on the sources of emissions as described by USEPA click here.

Formaldehyde

The primary source of formaldehyde emissions is mobile sources.
Since formaldehyde does not degrade quickly in the atmosphere, there
is also a significant contribution from background in a number of
counties. Formaldehyde is also formed in the atmosphere as a result of emissions
of other pollutants.

Hydrazine

Individuals may be exposed to hydrazine in the workplace or to small amounts in tobacco smoke. Hydrazine is used in agricultural chemicals (pesticides), chemical blowing agents, pharmaceutical intermediates, photography chemicals, boiler water treatment for corrosion protection, textile dyes, and as fuel for rockets and spacecraft. Accidental discharge into water, air, and soil may occur during storage, handling, transport, and improper waste disposal. However, hydrazine rapidly degrades in the environment and is rarely encountered. For additional information on the sources of emissions as described by USEPA click here.

Methyl Chloride (Chloromethane)

Outdoor concentrations of methyl chloride are mostly attributable background levels. Some is produced by industry, but it is also formed from combustion, and the breakdown of plastic waste.

Methyl Tert-Butyl Ether (MTBE)

MTBE was used as an additive for unleaded gasolines to achieve more efficient burning, and was therefore emitted primarily from mobile sources. It was omitted from gasoline in 2006.

Polycyclic Organic Matter (POM)

Polycyclic organic matter comprises a broad class of compounds
that are formed primarily from combustion, and are present in the
air in particulate form. The primary source of POM is area sources
(including all types of combustion and use of some consumer products).

 

For additional information on the sources of emissions as described
by USEPA, click here.

To evaluate risk from POM, USEPA assumed that 5% of the total POM
emissions were in the form of benzo(a)pyrene, a carcinogenic constituent
of POM. NJDEP used the same assumption in our risk assessment.

Perchloroethylene

Perchloroethylene is emitted mostly from dry cleaning.  Since perchloroethylene does not degrade quickly in the atmosphere, there is also a contribution from background concentrations. For additional information on the sources of emissions as described by USEPA click here.

Trichloroethylene

Most of the trichloroethylene used in the United States is released into the atmosphere from industrial degreasing operations. Exposure to trichloroethylene may happen to workers in the factories where it is manufactured or used, and to persons breathing air around these factories. Persons may also be exposed to trichloroethylene through the use of products containing the chemical and from evaporation and leaching from waste disposal sites. It is also an ingredient in adhesives, paint removers, typewriter correction fluids, and spot removers. Trichloroethylene is not thought to occur naturally in the environment. However, it has been found in underground water sources and many surface waters as a result of the manufacture, use, and disposal of the chemical.
