In-situ partitioning and bioconcentration of polycyclic aromatic hydrocarbons among water, suspended particulate matter, and fish in the Dongjiang and Pearl Rivers and the Pearl River Estuary, China.

Highlights: [•] PAHs are relatively higher in marine fish than in freshwater fish. [•] PAHs respectively show significant correlations with DOC, POC, and Chl a. [•] The log K _oc for PAHs is one order magnitude higher than the predicted. [•] The logBCF values in fish and their tissues are nonlinear in respect to log K _ow. [•] Lipid is related to PAHs in freshwater fish, but not in marine fishes. [Copyright &y& Elsevier]
