Urinary biomarker levels of polycyclic aromatic hydrocarbons in general population

Polycyclic aromatic hydrocarbons(PAHs),as members of a family of environmental pollutants widely existing in the environment,showed potential carcinogenicity.Single biomarker cannot completely represent the internal body burden.Many studies for the biomonitoring of occupational PAHs exposure have been reported.However,less studies have been published relatively for the general population exposed to PAHs.This article reviewed the urinary biomarkers,with focus on their levels of PAHs exposure in general population from studies published after the year of 2 000.
