Biomonitoring is one of the methods that allow to identify population groups that have significantly higher exposures to a particular chemical than th Cited by: Guideline Values for Benzene. The exposure limits for occupational exposure to benzene from various organizations such as European Commission, OSHA, NIOSH, ACIGH and SWA and Air Quality Guidelines (AQGs) and United Kingdom are summarized in Table 2 [22,24,25,26,27].Exposure evaluation of benzene concentrations in the various scenarios were for Cited by: Benzene is a ubiquitous airborne toxicant; to improve human health risk assessment for benzene exposure, better assessment of human exposure to benzene is needed. Biological markers provide a direct and objective means of monitoring the total exposure of individuals to specific chemicals.

Benzene in the environment: an assessment of the potential risks to the health of the population Article Literature Review (PDF Available) in Occupational and Environmental Medicine 58(1) Benzene is formed from both natural processes and human activities. Natural sources of benzene include volcanoes and forest fires. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke. Benzene is widely used in the United States. It ranks in the top 20 chemicals for production volume. Reference doses/concentrations for benzene have not been established. An oral risk assessment for benzene will be reviewed by an EPA work group and an inhalation risk assessment is currently under review (U.S. EPA, a). Benzene is carcinogenic in humans and animals by inhalation and in animals by the oral route of exposure. Evaluating Exposure. Individuals employed in industries that make or use benzene may be exposed to the highest levels of benzene. These industries include benzene production (petrochemicals, petroleum refining, and coke and coal chemical manufacturing), rubber tire manufacturing, and storage or transport of benzene and petroleum products containing benzene.
