An investigation on herbicide uses in two semi-urban catchments was performed simultaneously with sampling campaigns at six stations inside both watersheds from April to July 1998. Urban uses of herbicides exceeded agricultural uses, and transfer coefficients were also higher in urban areas. Therefore, the most used product in urban areas (diuron) was by far the most contaminating product. Householders accounted for 30% of all uses. The highest measured diuron concentration in water surface was 8.7 microg l(-1) due to its use on impervious surfaces. Compared to EEC standards for drinking water production (0.1 microg l(-1)), it is clear that suburban uses of herbicides may severely endanger drinking water production from river water.
1998年4月至7月,在两个半城市集水区开展了除草剂使用情况调查,同时在两个流域内的六个站点进行了采样活动。城市中除草剂的使用量超过了农业用量,城市地区的转移系数也更高。因此,城市地区使用最多的产品(敌草隆)是迄今为止污染最严重的产品。家庭用户占所有用量的30%。由于其在不透水表面的使用,水面测得的最高敌草隆浓度为8.7微克/升。与欧盟饮用水生产标准(0.1微克/升)相比,很明显郊区除草剂的使用可能会严重危及河水用于饮用水生产。
