PFOS和PFOA的水生生物基准探讨及对中国部分水体生态风险的初步评估
Development of Aquatic Life Criteria for PFOS and PFOA and Preliminary Assessment for the Ecological Risk of Some Water Bodies in China
摘要
Abstract
Perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) are widely existing as two typical perfluorinated pollutants in water body in China. There are no aquatic life criteria for PFOS and PFOA in China now. In this study, we collected the toxic data of PFOS and PFOA on local species in China to develop the aquatic life criteria using the sensitive species rank method (SSR) recommended by US Environmental Protection Agent (US EPA). The results showed that the acute and chronic criterion values were 32.9 µg·L-1 and 1.97 µg·L-1 for PFOS, 46.1 mg·L-1and 5.46 mg·L-1 for PFOA, respectively, which had the difference of magnitude. The ecological risk of PFOS and PFOA exposed in the part of the freshwater bodies were assessed by the risk quotient (RQ) method and the results showed that PFOS and PFOA had not posed significant ecological risk, which was at the acceptable level.关键词
