  • 摘要: The aquatic ecosystem maybe significantly affected by polycyclic aromatic hydrocarbons (PAHs) released from fresh water sediments. In order to protect biodiversity, the spatial distribution and sources of PAHs in the sediment of Wolong Lake in Northeast China were studied. A total of 17 surface sediment samples were collected and 12 PAHs were analyzed. The results were as follows. The concentration of total PAHs (TPAHs) ranged between 1412.9 μg/kg and 3948.3 μg/kg (dry weight). Indeno[1, 2, 3-c, d] pyrene was the dominant contaminant which accounted for 87%-98% of TPAHs. Diagnostic ratios of PAHs and principal component analysis showed that biomass combustion and vehicle emissions were likely to be the dominant sources of PAHs in the sediment. PAHs can be considered safe in the context of environmental and human health protection, based on the overall toxicity. Individual PAHs were positively correlated with total organic carbons. These results will be helpful to control PAHs and protect the aquatic ecosystem in the lake.

摘要: The aquatic ecosystem maybe significantly affected by polycyclic aromatic hydrocarbons (PAHs) released from fresh water sediments. In order to protect biodiversity, the spatial distribution and sources of PAHs in the sediment of Wolong Lake in Northeast China were studied. A total of 17 surface sediment samples were collected and 12 PAHs were analyzed. The results were as follows. The concentration of total PAHs (TPAHs) ranged between 1412.9 μg/kg and 3948.3 μg/kg (dry weight). Indeno[1, 2, 3-c, d] pyrene was the dominant contaminant which accounted for 87%-98% of TPAHs. Diagnostic ratios of PAHs and principal component analysis showed that biomass combustion and vehicle emissions were likely to be the dominant sources of PAHs in the sediment. PAHs can be considered safe in the context of environmental and human health protection, based on the overall toxicity. Individual PAHs were positively correlated with total organic carbons. These results will be helpful to control PAHs and protect the aquatic ecosystem in the lake.
