EPA List of Hazardous Pollutants

The U. S. Environmental Protection Agency (EPA) is a federal organization responsible for the control and regulation of hazardous pollutants. EPA is required to control 187 hazardous air pollutants, such as benzene, found in gasoline. The Clean Air Act, amended in 1990, contains a list of hazardous air pollutants, which can cause cancer and other health effects, such as birth defects, as well as damage to the wildlife.

Methyl Group

• Methyl bromide can cause cancer, genetic damage and negatively affect the developing child. Historically used in pesticides, this chemical was phased out in the U.S. in 2005, according to EPA. Methylhidrazine is a recognized carcinogen, as well as methyl iodide, which is still used as insecticide in some states, such as California.

Lead Compounds

• Lead is present in compounds such as lead acetate, lead chloride, lead chromate and lead nitrate. These compounds are used in the manufacture of batteries, metal products, ceramic glazes and paints. Lead compounds are a carcinogen and can cause damage to organs such as the liver and kidneys.

Vynil Compounds

• Vinyl compounds such as vinyl acetate are used in the PVC and polymers industry. Short-term inhalation of vinyl acetate has resulted in eye irritation and upper respiratory tract irritation in workers. Although carcinogenic effects have not been reported in humans, an increased incidence of nasal cavity tumors has been observed in rats exposed by inhalation. In one drinking water study, an increased incidence of tumors was reported in rats.

Formaldehyde

• EPA considers formaldehyde a likely human carcinogen. Formaldehyde is used to produce resins and as an intermediate in the synthesis of other chemicals. Inhalation exposure to formaldehyde in can also result in respiratory symptoms, as well as eye, nose and throat irritation. The major sources of formaldehyde are power plants, manufacturing facilities, incinerators and automobile exhaust emissions.
