在葡萄牙农业区使用的杀虫剂在地表水和地下沃茨中被发现。在1983 - 1999年采集的三个流域的地表水中，从监测的农药中检测到杀虫剂和除草剂，特别是阿特拉津、氯苯硫磷（Z + E）、α-和β-硫丹、林丹、灭草酯和西玛津，分别达到0.63、31.6、0.18 mug/L的最大值（甲型硫丹）、0.18微克/升（乙型硫丹）、0.24、48和0.3微克/升。1991 ~ 1998年在7个农业区的威尔斯井中采集的地下水中，检测到几种监测除草剂：甲草胺、阿特拉津、异丙甲草胺、嗪草酮和西玛津，最大浓度值分别为0、30、56、1.4和0.4 μ g/L。最常检测到的除草剂是阿特拉津（64%）、西玛津（45%）和甲草胺（25%）。除此之外，葡萄牙地表水和地下沃茨中也可能存在受监测的农药。因此，为了改善分析条件，使用多残留方法和自动化技术是可取的，在未来的工作。(C)2002年由Elsevier Science Ltd.出版
Pesticides used in Portuguese agricultural areas have been found in surface and ground waters. In the surface water collected in three river basins from 1983 to 1999, insecticides and herbicides were detected from the monitored pesticides, particularly atrazine, chlorfenvinphos (Z + E), alpha- and beta-endosulfan, lindane, molinate and simazine, reaching the maximum values, respectively, of 0.63, 31.6, 0.18 mug/L (alpha-endosulfan), 0.18 mug/L (beta-endosulfan), 0.24, 48 and 0.3 mug/ L. In the ground water collected from the wells of seven agricultural areas from 1991 to 1998, several monitored herbicides were detected: alachlor, atrazine, metolachlor, metribuzine and simazine, reaching the maximum concentration values of 0, 30, 56, 1.4 and 0.4 mug/L, respectively. The herbicides more frequently detected were atrazine (64%), simazine (45%) and alachlor (25%). Other than these, the monitored pesticides can be present in Portuguese surface and ground waters. Therefore, to improve the analytical conditions, the use of multiresidue methods and automated techniques are desirable in future work. (C) 2002 Published by Elsevier Science Ltd.
