Benzene

Benzene

Benzene is a liquid heaving no color but a sweet odor. It evaporates quickly into the air and is slightly soluble in water. It is flammable and it forms from natural processes and also as human activities. 

Benzene is used extensively in the United States; ranks # 20 on the list of chemicals of peak production. Some industries use benzene to make other chemicals used to make resins, nylon, plastics and other synthetic fibers. Benzene is also used to make certain types of rubbers, dyes, detergents, lubricants, drugs and pesticides. Volcanoes and forest fires are natural sources of benzene. Benzene is also a natural component of oil, gasoline and cigarette smoke.

Benzene can pass into air from soil and water.

In the air reacts with other chemicals and breaks down within few days.

The benzene in the air can be dragged to the ground by rain or snow.
It breaks down more slowly in water and soil and can enter groundwater through the soil.

Benzene does not accumulate in plants or animals.
