The Federal Clean Air Act regulates 187 chemicals that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects.
Listed hazardous air pollutants include benzene, which is widely used in the United States; it ranks in the top 20 chemicals for production volume. Some industries use benzene to make other chemicals that are used to make plastics, resins, and nylon and synthetic fibers. Benzene is also used to make some types of rubbers, lubricants, dyes, detergents, drugs, and pesticides. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke.

1,3-Butadiene is a chemical made from the processing of petroleum. Most of the 1,3-Butadiene manufactured is used in the production of synthetic rubber. It is also used in the production of plastics and acrylics. These synthetic materials are used to manufacture automotive tires and tire products, automotive hoses, belts, seals, and gaskets. It is also used as a chemical intermediate in the production of some fungicides, and in the manufacture of latex adhesives, nylon carpet backing, paper coatings, pipes, conduits, electrical components and luggage. Small levels of 1,3-Butadiene are found in gasoline. For more information follow this link.
