Abstract:Based on the observed PAHs concentrations of different rivers in China, one hazard quotient was defined to screen the target compounds. Seven PAHs, which posed potential threat to aquatic ecosystem, including phenanthrene, anthracene, fluoranthene, pyrene, benzo[a]anthracene, chrysene and benzo[a]pyrene, were screened. Combined with the toxicity data of PAHs to aquatic organisms, the probabilistic risk approach was applied to assess the ecological risk of the seven PAHs to aquatic ecosystem. Among all the 16 investigated PAHs, ecological risk of anthracene was the highest, while the risk of chrysene was the lowest. The ecological risk of 16 individual PAHs followed the order of anthracene>pyrene>benzo[a] anthracene>fluoranthene>benzo[a]pyrene>phenanthrene>chrysene.
