摘　　要：荧蒽是一种对水生生物有害的优控多环芳烃,在国内外水体中广泛存在.然而,在目前关于荧蒽的科学研究中,其基准阈值报告较为少见,由于本土物种生态毒理学数据对荧蒽基准阈值的研究分析尤为重要,数据的缺失成为阻碍其发展的主要原因.本文通过开展急性生态毒理学和慢性生态毒理学实验,并利用US EPA“指南”推荐的方法,推导了荧蒽的基准阈值,其中急性实验对象为9种本土水生生物,慢性实验为3种.推导结果表明:荧蒽本土水生生物急性基准阈值(CMC)为0.570 mg·L^(−1),慢性基准阈值(CCC)为0.174 mg·L^(−1);另外,鉴于本土和非本土物种之间的巨大差别,文章中采用了SSD(species sensitivity distribution),即物种敏感性分布法,根据对二者敏感度分布的分析结果,可以发现本土与美国物种在敏感性分布上一致性较低,这也表明在推导我国荧蒽水生生物基准阈值时,可直接利用美国水生生物毒性数据的可能性很小.Fluoranthene(FLU)is a priority polycyclic aromatic hydrocarbon(PAH)which is toxic to aquatic organisms.However,there has been no paper dealing with water quality criteria(WQC)of FLU due to the shortage of its toxicity data of different taxonomic levels.In the present study,toxicity data were obtained from 9 acute toxicity tests and 3 chronic toxicity tests using 9 Chinese native aquatic species from different taxonomic levels.Based on these toxicity data,the criterion maximum concentration and criterion continuous concentration were developed according to US EPA guidelines,and the values were 0.570 mg·L^(−1)and 0.174 mg·L^(−1),respectively.Furthermore,the comparison of the differences of species sensitivity distributions(SSD)between native and non-native species shows significant difference in the sensitivity distribution between native and nonnative species,which indicated that using toxicity data of American species directly to derive the water quality criteria of FLU was impossible.
