Health Risk Assessment of Polycyclic Aromatic Hydrocarbons: A Review
نویسندگان
چکیده
Accepted: 29/12/2014 Abstract Polycyclic Aromatic Hydrocarbons (PAHs) are ubiquitous environmental contaminants and found almost everywhere. Most of PAHs are formed during the incomplete combustion of organic matter such as wood, petroleum product, coal and tar. These chemicals are biologically active and pose a risk for human health because of their potentially toxicity such as carcinogenicity, teratogenecity, mutagenicity and genotoxicity. The aim of this paper is to give current information on PAHs exposure, worldwide spread distribution and health risk associated with their exposure.
