我国区域性水体农药污染现状研究分析

Study on Status of Regional Water Pollution by Pesticides in China

以4大流域为基础,较为全面地概述了我国区域性农药污染情况,并对其污染原因进行了分析。结果表明:长江流域有机磷农药、氨基甲酸酯类农药以及部分拟除虫菊酯类农药的的残留量很高;珠江流域农药污染情况较轻,检出量均低于我国地表水环境质量标准;黄淮海流域和松辽流域主要检出农药为酰胺类和三嗪类农药,但具体检出物质存在差异。研究分析表明各流域农药污染与该区域的农作物种类有重要关系。

Based on four river basin,the status of regional water pollution by pesticides in China were summarized,the reasons were analyzed.The results show that residues of organophosphorus pesticides,carbamate pesticides and pyrethroid pesticides are higher in the Yangtze River Basin.The pesticide pollution in the Pearl River Basin is slight,which the concentrations of pesticides are lower than the limits in the national environmental quality standards for surface water.The mainly pollutants of pesticides in the Huang-Huaihai River Basin and the Song-Liao River Basin are amides and triazines,but the specific detection components are different.Moreover,the study shows that particular pesticide pollutants in each basin has an important relationship with the planted crop species.
