The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.

Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent. It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9] Its IUPAC name is trichloroethene. Trichloroethylene has been sold under a variety of trade names.
An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health .
The chemicals — trichloroethylene and perchloroethylene (PCE or perc) — can cause multiple kinds of cancers and damage to the kidney, liver and immune and nervous systems at high exposure ...
There are three levels of PAC value (1 to 3) where each successive value is associated with an increasingly severe effect from a higher level of exposure. Each level is defined as follows: PAC-1 : Mild, transient health effects. PAC-2 : Irreversible or other serious health effects that could impair the ability to take protective action.
Acute Exposure Guideline Levels (AEGLs) set levels of chemical concentration that pose a defined level of risk to humans (the general population, including susceptible individuals). [ 1 ] [ 2 ] [ 3 ] These levels are used in preventing and responding to disasters .
