扑草净对人体健康及水生环境的安全性评价

在水产养殖中，扑草净作为一种三嗪类除草剂被违规使用。近年来中国水产品扑草净残留频频被检出，甚至超过水产品进口国命令检查的基准值，影响了正常的水产品出口贸易。但目前水产品中扑草净的最大残留限量(MRL)未见报道，而较难降解的扑草净对水生环境存在安全隐患。以美国环境保护署(EPA)公布的扑草净相关报告为主要依据，文章分析了国内外扑草净残留的限量标准现状，详细介绍了扑草净对人体健康的安全性评价，阐述了扑草净对水生环境的生态毒理效应，并综述了水产品中扑草净的检测方法及其风险评估研究现状，以期引起广泛的关注和重视，并为把扑草净作为水产用药纳入国家标准目录及建立正常的水产品出口贸易秩序提供基础资料。

Safety Assessment of Prometryn on Human Health and Aquatic Environment

As a kind of triazine herbicides, prometryn has been applied illegally in aquaculture. In recent years, prometryn residue in aquatic products in China has been frequently detected, and even exceeded the baseline of command check set by aquatic products import countries, affecting the normal export trade of aquatic products. However, the maximum residue limit (MRL) of prometryn in aquatic products has not been reported yet. As prometryn is difficult to degrade, it may be a potential safety hazard to aquatic environment. In order to attract widespread concern and attention, and provide basic data for bringing prometryn into the national standard directory as veterinary drugs and establishing normal export trade order of aquatic products, status of prometryn residue limited standards at home and abroad were analyzed in this paper based on the reports on prometryn of Environmental Protection Agency (EPA), safety evaluation of prometryn on human health was introduced in detail, ecotoxicological effects of prometryn on aquatic environment were summarized, and the detection methods of prometryn in aquatic products and related risk assessment research status were reviewed.
