Conteúdo: | Since the mehods for the analysis of pyrethroids described in the literature apply to the analysis of grains and little has been reported on the analysis of corn, various of these methods were tested in order to choose the most adequate method and adapt it for the analysis of corn husks and ground corn ears. The recoveries in the clean-up phase were first determined using the methods of Mestres et al. and of Hascoet and Andre, resulting in recoveries of 96,0 +/-3.1and 98.0+/-2.0%, respectively. After evaluating the accuracy, precision, ease, speed and cost of analysis, the clean up method of Hascoet and Andre was chosen. The various extraction methods were then tested. The best recoveries were obtained using the method of Gorbach and Thier modified for use with husks and ground ears. The total recoveries for the extraction and clean up, performed in triplicate, for each contamination level were 89% (1 ppm), 98% (0.4 ppm) and 81% (0.1 ppm) for ground ears and 81% (1 ppm), 91% (0.4 ppm) and 89% (0.1 ppm) for husks.
