摘　　要：吡啶硫酮锌是一种广谱的真菌和细菌的抑菌剂和常用的防污剂,被广泛用于去屑剂、船舶防污涂料、农用杀菌剂等。水环境中吡啶硫酮锌的残留具有较高的风险,我国尚缺乏吡啶硫酮锌的淡水水生生物基准值。为保护我国淡水水生生物,维护水生生态系统结构和功能的完整性以及生物的多样性,本研究首次推导了我国流域水环境的吡啶硫酮锌水生生物基准。根据美国环境保护局的ECOTOX毒性数据库和我国知网数据库以及其他部分文献,收集和筛选吡啶硫酮锌对我国淡水水生生物的急慢性毒性数据,共4门10科13种急性毒性数据和2门4科4种慢性毒性数据。采用我国推荐技术指南中的物种敏感度分布法(EEC-SSD)推导吡啶硫酮锌的水生生物基准,得出吡啶硫酮锌的急性和慢性基准分别为2.347μg·L^(-1)和0.798μg·L^(-1)。本研究对物种敏感度排序法(SSR)、物种敏感度分布法(SSD)、评价因子法进行比较,发现SSR法与SSD法所得结果一致,均在同一数量级,评价因子法相对保守。本论文研究结果可为吡啶硫酮锌水质标准制定和流域水生态环境管理提供科学依据。Zinc pyrithione is widely used as an anti-dandruff agent,anti-fouling coating for ships and agricultural fungicide and so on due to its broad-spectrum antibacterial activity and excellent antifouling performance.When the concentration of discharged zinc pyrithione in the water environment exceeds a certain content,it may cause an adverse effect to aquatic organisms.In order to protect freshwater aquatic organisms and maintain the structural and functional integrity of aquatic ecosystem and biological diversity,this study deduced the aquatic life water quality criteria of zinc pyrithione in the water environment of Chinese watershed for the first time.The acute and chronic toxicity data of zinc pyrithione to Chinese freshwater aquatic life were collected from the ECOTOX toxicity database of the United States Environmental Protection Agency(US EPA),the database of China Knowledge Network and other literature.Then,a total of 13 species acute toxicity data from 10 families in 4 phyla and 4 species chronic toxicity data from 4 families in 2 phyla were screened out.Subsequently,the species sensitivity distribution methods in the Chinese recommended technical guidelines,including species sensitivity ranking method(SSR),species sensitivity distribution method(SSD),and evaluation factor method,were adopted to derive the water quality criteria of zinc pyrithione.The results showed that the acute and chronic criteria values of zinc pyrithione for Chinese aquatic life were 2.347μg·L^(-1) and 0.798μg·L^(-1),respectively.The aquatic life water quality criteria of zinc pyrithione obtained by the SSR method and the SSD method were in the same order of magnitude.The derived aquatic life water quality criteria of zinc pyrithione using evaluation factor method was relatively conservative.This study could provide a scientific basis for the development of water quality criteria of zinc pyrithione and a data support for the watershed-based aquatic ecological environment management.
