为评价农业和城市活动对河水农药污染的贡献，对日本东广岛黑泽河水中农药敌草隆、伊加罗1051和杀虫硫磷进行了为期一年的研究。样品用反相高效液相色谱系统分析。敌草隆、伊加罗1051和杀虫硫磷的最高农药浓度分别为4620 ng/L、50 ng/L和370 ng/L。虽然在所有地点都检测到了敌草隆和苯硫隆，但伊加洛尔1051只出现在出水，这是一个高密度的城市和工业区，也是这些杀虫剂浓度最高的地区。敌草隆和敌硝硫磷表现出的模式与农业活动有关。此外，敌草隆和杀虫硫磷的浓度与广岛县的农药使用数据相关。Irgarol 1051表现出与敌草隆和杀菌丹不同的图案，其来源被认为是涂料。据指出，出泉采样点的水样分别有78%和42%超过欧洲联盟(欧盟)关于敌草隆和杀虫硫磷的指导方针。(C)2015爱思唯尔B.V.保留所有权利。
A studywas conducted on the pesticides Diuron, Irgarol 1051 and Fenitrothion in Kurose Riverwater, Higashi Hiroshima, Japan for a period of one year to assess the contribution of agriculture and urban activities on pesticide pollution of the river. Samples were analysed by a reverse phase HPLC system. The maximum pesticide concentrations were; 4620 ng/L, 50 ng/L and 370 ng/L for Diuron, Irgarol 1051 and Fenitrothion, respectively. While Diuron and Fenitrothionwere detected at all sites, Irgarol 1051was only present at Izumi, a high density urban and industrial area which also registered the highest concentrations of the pesticides. The pattern showed by Diuron and Fenitrothion was linked to farming activities. Also, Diuron and Fenitrothion concentration correlated with pesticide utilization data for Hiroshima Prefecture. Irgarol 1051 showed a different pattern to that of Diuron and Fenitrothion and its source was attributed to paint. It was noted that 78% and 42% of water samples at Izumi sampling site exceeded the European Union (EU) guidelines for Diuron and Fenitrothion, respectively. (C) 2015 Elsevier B.V. All rights reserved.
