Sources, concentrations, fate and effects of polycyclic aromatic hydrocarbons [PAHs] in the environment. Part A: PAHs in air

Abstract

This paper provides a review of contemporary information on the concentrations, burdens and fate of polycycylic aromatic hydrocarbons (PAHs) in the atmosphere, with reference to the historical trends in PAH emissions. The main anthropogenic sources of PAHs and their effect on the concentrations of these compounds in air on a national-regional scale are discussed. The fate of PAHs in the air, their persistence and the main mechanisms of their losses are presented. Health hazards associated with PAH air pollution is stressed.
