Benzene: reflections on public health, environmental presence and biological indicators used for the determination of exposure

The indiscriminate use of an increasing number of chemicals is growing and associated environmental contamination has brought serious consequences for the public health system due to rising damage to human health. One of the substances that have attracted great interest due to contemporary contamination is benzene, aromatic compound classified by International Agency for Research on Cancer as a carcinogen known. The aim of this study was develop and discuss an overview of the contamination by benzene, its metabolism, health endings and their environmental and biological determination based on literature data existing. The survey provided access to more than 200 scientific papers, both nationally and internationally, demonstrating the relevance of the topic and the need to minimize human exposure to this substance. The majority is concerned with exploring the metabolism and investigates indicators of exposure, many already widely studied and with serious limitations. However, a growing number of researchers are committed to elucidate factors related to interference susceptibility and exposure on protein and genetic material. Indicators of innovative exhibition has been proposed with the aim of complementing gaps of information previously obtained, contributing to the design of the structure of the organ biology systems upon exposure to benzene.
