It can have negative effects on the liver, kidney, lungs, heart and brain and can also cause excessive bleeding that can affect the immune system, increasing the chance for infection. Exposure to benzene may also be harmful to the reproductive organs, with evidence of irregular menstrual periods in women exposed to high levels of benzene over many months. The International Agency for Cancer Research and the EPA have determined benzene to be carcinogenic to humans.

Benzene (chemical formula C6H6) is also referred to as benzol, benzole and cyclohexatriene(an isomer of benzene). It is carnengenic colorless or light-yellow liquid, and natural component of crude oil, which can increase the risk of leukemia aswell as various other blood disorders.

It is used as a solvent in the chemical and pharmaceutical industries, can be found in adhesives, glues, nylon, plastics, paint strippers, resins, synthetic fibres, in some rubber types, lubricants, dyes, detergents, drugs, and pesticides.
