中文摘要:

      三嗪类除草剂是我国使用历史较久的传统除草剂之一。因其除草效果良好, 在我国农业领域中有着举足轻重的地位。三嗪类除草剂具有亲水亲脂性特点, 经过环境的迁移, 易于在水产品中富集, 并通过食物链的传递对人类造成健康威胁。近年来三嗪类除草剂在水环境及水产品中的污染问题逐渐减少, 但仍有部分样品含量超标现象。三嗪类除草剂对水生动物的毒性较高, 对其免疫功能、生长发育、呼吸系统等都存在一定影响。本文介绍了三嗪类除草剂的代表性市场产品、理化性质、分析技术、在水环境以及水产品中的污染情况以及对水生动物的毒性效应。本研究为今后三嗪类除草剂在水环境及水产品中分析技术的创新及优化、污染调查研究、对水生动物的毒性效应观察及降解提供理论依据与支持。

英文摘要:

      Triazine herbicides are among the traditional herbicides with a long history of use in China. Because of its good weed control effect, it has a pivotal position in China agricultural field. Triazine herbicides, being both hydrophilic and lipophilic, tend to accumulate in aquatic products after environmental migration, and pose health risks to humans through the food chain. The contamination of triazine herbicides in water and aquatic products has been decreasing in recent years, but there are still some samples with excessive levels. Triazine herbicides pose a high toxicity to aquatic animals and can adversely affect their immune function, growth, and respiratory systems. This paper described representative marketed products of triazine herbicides, their physicochemical properties, analytical techniques, contamination in the aquatic environment as well as in aquatic products, and toxic effects on aquatic animals. This study provided theoretical basis and support for the innovation and optimization of analysis technology of triazine herbicides in water environment and aquatic products, pollution investigation, observation and degradation of toxic effects on aquatic animals.
