Areas of heavy traffic, gas stations, and areas near industrial sources may also have higher air levels. However, the ECHA review shows that some member states have a significantly lower OEL value which probably indicates the ‘direction of travel’ for the OEL given that the World Health Organisation (WHO) says there is no safe level of exposure. We’ve invested more than $4.9 billion in cancer research since 1946, all to find more – and better – treatments, uncover factors that may cause cancer, and improve cancer patients’ quality of life. According to the Agency for Toxic Substances and Disease Registry (ATSDR) (2007), benzene is both a man-made and naturally occurring chemical from processes that include: volcanic eruptions, wild fires, synthesis of chemicals such as phenol, production of synthetic fibers, and fabrication of rubbers, lubricants, pesticides, medications, and dyes. Benzene is highly volatile, and exposure occurs mostly through inhalation. Accessed at http://cfpub.epa.gov/ncea/iris/iris_documents/documents/subst/0276_summary.pdf on October 15, 2015.

Identifying industries with either 1) workers exposed to high levels of benzene or 2) a larger number of workers exposed to benzene is important in guiding cancer prevention efforts to prioritize exposed groups and target resources most effectively. The American Cancer Society is a qualified 501(c)(3) tax-exempt organization. Skin exposure to benzene can result in redness and blisters.
