英文摘要:
To assess the environmental risks of polycyclic aromatic hydrocarbons (PAHs), 48 and 45 sediments were collected from the Yangtze River Estuary (YRE) and Pearl River Estuary (PRE), respectively. The toxicity equivalency concentration (TEQ) in the YRE and PRE were ranged from 1.68 to 76.13 and 9.28 to 129.24�ng�TEQ�g−�1, respectively. Results of risk quotient suggest that ecological risks of two estuaries are at a moderate level, but are higher in the PRE than YRE. The increment lifetime cancer risks (ILCR) from the YRE via ingestion and dermal contact were 1ï¿½× 10−�6to 5.6ï¿½× 10−�5and 4ï¿½× 10−�6to 1.6ï¿½× 10−�4, and ranged from 7ï¿½× 10−�6to 9.4ï¿½× 10−�5and 2ï¿½× 10−�5to 2.8ï¿½× 10−�4in the PRE. ILCR results suggest that some low and moderate cancer risk exists in the YRE and PRE. Therefore, monitoring and control measures should be carried out immediately to reduce or eliminate the risks to human health from environmental exposure. � 2016 Elsevier Ltd
