The use of pesticides to control pests, diseases and weeds in crops of agricultural interest aims at the increase of production. The degradation of applied compounds or their conversion into other products, does not necessarily mean the loss of biological activity, and many times, this conversion can result in even more toxic and active products. The study of the pesticides persistence in crops is of great importance in order to evaluate the risks of environmental contamination. In this study, an analytical method for the residual determination of the insecticide carbofuran and the herbicide quinclorac in the water of irrigated rice farming, using SPE and HPLC-DAD, was developed and validated. The method consists of the pre-concentration o...
