全氟辛烷磺酸(PFOS)和全氟辛酸(PFOA)是两种应用广泛的全氟化合物。它们已经在各种环境介质中被检测到，并损害了水生生物和系统。本研究探讨了全氟辛烷磺酸和全氟辛烷磺酸对淡水生物的毒性效应，以保护水生生态系统。分析了9种水生生物的急性毒性试验数据和3种水生生物的慢性毒性试验数据，以及已发表的国内外文献中具有代表性的中国水生生物的全氟辛烷磺酸和全氟辛烷磺酸毒性数据。采用美国环保局推荐的方法，计算出全氟辛烷磺酸的标准最高浓度为3.78 mg/L，标准连续浓度为0.25 mg/L；全氟辛烷磺酸的标准最高浓度为45.54 mg/L，标准连续浓度为3.52 mg/L，为制定水质标准和水生态风险评价提供了科学依据。
Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are two widely used perfluorinated compounds. They have been detected in various environmental media and have harmed aquatic life and systems. The toxic effects of PFOS and PFOA on freshwater organisms were explored with the goal of protecting aquatic ecosystems in this study. Data from acute toxicity tests using nine aquatic species and chronic toxicity tests using three species were analyzed, along with PFOS and PFOA toxicity data for representative Chinese aquatic biota that have been published in the Chinese and international literature. Using the method recommended by the United States Environmental Protection Agency (US EPA), the criterion maximum concentration (CMC) for PFOS was calculated to be 3.78 mg/L, and the criterion continuous concentration (CCC) was calculated to be 0.25 mg/L. For PFOA, the CMC was calculated to be 45.54 mg/L, and the CCC was calculated to be 3.52 mg/L. The criteria derived in this study provide the scientific basis for development of water quality standards and aquatic ecosystem risk evaluation.
