  Polycyclic aromatic hydrocarbons (PAHs) are one of the most important persistent organic pollutants (POPs) and are widespread in surface waters in China.Based on the observed concentrations of different rivers in China,the quotient method was used to screen the potential risk of PAHs to aquatic organisms.Seven PAHs,which might pose potential threat to aquatic ecosystem,including phenanthrene,anthracene,fluoranthene,pyrene,benzo[a]anthracene,chrysene and benzo[a]pyrene,were screened.
