The aim of this work was to study the behaviour of some of the main citrus selective residual herbicides in the water of an irrigation well. The chemicals used were: atrazine, simazine, terbuthylazine, terbutryn, terbumeton, bromacil and diuron. The simetric triazines and bromacil were analyzed by gas chromatography and diuron by HPLC. The mentioned pesticides were introduced in the well in order to simulate a point-source contamination. Levels of contamination of the well due to herbicide application were about 1 mg/l, however, dissipation of the herbicides was almost complete 8 days after application, except for bromacil and diuron which persisted longer than the s-triazines.
这项工作的目的是研究一些主要的柑橘类选择性残留除草剂在灌溉井水中的行为。所使用的化学品有：莠去津、西玛津、特丁津、特丁净、特丁通、溴莠敏和敌草隆。对称三嗪和溴莠敏用气相色谱法分析，敌草隆用高效液相色谱法分析。将上述农药引入井中以模拟点源污染。由于施用除草剂导致的井水污染水平约为1毫克/升，然而，除了溴莠敏和敌草隆比均三嗪持续时间更长外，除草剂在施用后8天几乎完全消散。
