Fluoranthene (FLU) has shown relatively high toxicity to aquatic life as a priority polycyclic aromatic hydrocarbon (PAH). Considering the toxic effects of FLU on aquatic organisms and its high detection frequency in the aquatic environment, it is necessary and critical to derive FLU water quality criteria (WQC) for the protection of aquatic organisms and ecological risk assessment. However, due to the lack of toxicity data at different classification levels, there has been no research about the WQC of FLU. In this study, nine acute and three chronic toxicity tests were carried out on 9 Chinese indigenous aquatic species from different classification levels to obtain toxicity data. According to the US EPA guidelines, the criterion maximum concentration of 0.570 mg/L and the criterion continuous concentration of 0.174 mg/L were developed. There is no significant difference when comparing the species sensitivity distributions between indigenous and exotic species. Therefore, it is possible to use toxicity data from organisms in different areas for ecological risk assessment of FLU. CAPSULE: We compared the sensitivity between indigenous and exotic aquatic species for fluoranthene and derived its water quality criteria.
荧蒽（FLU）作为一种优先控制的多环芳烃，已显示出对水生生物具有较高毒性。鉴于FLU对水生生物的毒性影响及其在水环境中的高检出频率，制定FLU水质基准（WQC）对于保护水生生物和进行生态风险评估是必要且至关重要的。然而，由于缺乏不同分类水平下的毒性数据，尚未有关于FLU水质基准的研究。本研究针对9种不同分类水平的中国本土水生生物进行了9项急性毒性试验和3项慢性毒性试验，以获取毒性数据。根据美国环境保护局（US EPA）的指导方针，制定了0.570 mg/L的基准最大浓度和0.174 mg/L的基准连续浓度。比较本土物种和外来物种的物种敏感性分布时，未发现显著差异。因此，有可能使用不同地区生物的毒性数据进行FLU的生态风险评估。摘要：我们比较了本土和外来水生物种对荧蒽的敏感性，并推导了其水质基准。
