  • 摘要: 安徽省阜阳市颍州西湖是我国中部地区的一个典型的农业小流域，小流域内农药的滥用可能会引发水生态风险。通过检测该流域水中4个月份（1月、3月、4月和6月）内29种（6类）常见农药的污染水平，计算流域中相应农药的风险熵，以此评估该流域内农药类微污染物的赋存浓度特征及生态风险。结果表明，农药整体存在从西湖上游河网富集到西湖主体中的趋势；采样时间横跨枯水期与丰水期，农药的总体检出频率随降雨量的升高而不断上升，总体检出水平大幅升高后略微下降。流域内主要的农药类微污染物为多菌灵（3.2～687.4 ng·L-1）、异丙甲草胺（0.4～69.9 ng·L-1）、多效唑（0.8～39.8 ng·L-1）、戊唑醇（0.2～278.2 ng·L-1）和三唑醇（0.8～22.3 ng·L-1），而生态风险多源于多菌灵（40.3%～61.6%）、戊唑醇（4.7%～35.6%）、克百威（0.2%～37.6%）、吡虫啉（7.5%～11.2%）和异丙甲草胺（3.2%～12.0%）。农药的检出水平与生态风险并不完全等价，因此需结合农药类微污染物的赋存浓度及其生态风险来评估农药对农业小流域潜在的危害，为农业小流域内相关产业规划提供参考。
    Abstract: The West Lake in Fuyang City, Anhui Province is a typical small agricultural basin in the central region of China, and the use of pesticides in the small basin may induce aquatic ecological risk. To assess the occurrence and ecological risk of pesticides in this small agricultural basin, the concentrations of 29 pesticides (six categories) in four months (Jan., Mar., Apr., and Jun.) in the basin were investigated, and the risk quotient were calculated. It was found that pesticide concentrations showed the overall tendency that pesticides were enriched from the upper river network to the West Lake. The sampling time covered dry season and wet season. In general, the detection frequency of pesticides raised continuously with the increase of rainfall, and the detection concentration increased significantly and then slightly decreased. The main pesticides in the basin were carbendazim (3.2~687.4 ng·L-1), metolachlor (0.4~69.9 ng·L-1), paclobutrazol (0.8~39.8 ng·L-1), tebuconazole (0.2~278.2 ng·L-1) and triadimenol (0.8~22.3 ng·L-1). However, the ecological risk was mainly induced by carbendazim (40.3%~61.6%), tebuconazole (4.7%~35.6%), imidacloprid (0.2%~37.6%), metolachlor (7.5%~11.2%), carbofuran (3.2%~12.0%). The detection concentration of pesticides is not entirely equivalent to their ecological risk. Therefore, it is reasonable to combine the concentration of pesticides and their ecological risk to evaluate the potential hazards induced by pesticides in small basin, which can provide further guidance for related industry planning in small basin.
