Abstract

Matrix effects observed during the multiresidue analysis of seven organochlorine pesticides in six different agricultural products with GC-ECD were assessed. The presence of matrix coextractives, a major cause of observed matrix effects, directly and/or indirectly influenced the chromatographic responses of some pesticides. Two types of external calibrations, solvent calibration (SC) and matrixmatched calibration (MC), were used to assess matrix effects. Greater matrix effects were observed at the lower concentrations of each pesticide. The extent of matrix effects varied unpredictably with matrix type. Among the analyzed pesticides, iprodione, cyhalothrin, and cypermethrin exhibited greater matrix effects (>150%) for almost all matrices. The pesticide recovery rates obtained with MC were not statistically different from a 100% recovery rate in most samples, which indicates that MC may diminish the overestimates occurred due to matrix effects in GC analysis.

摘要

评估了采用气相色谱 - 电子捕获检测器（GC - ECD）对六种不同农产品中七种有机氯农药进行多残留分析时观察到的基质效应。基质共提取物的存在是观察到的基质效应的主要原因，它直接和/或间接影响了某些农药的色谱响应。使用了两种类型的外部校准，即溶剂校准（SC）和基质匹配校准（MC）来评估基质效应。在每种农药的较低浓度下观察到更大的基质效应。基质效应的程度随基质类型不可预测地变化。在所分析的农药中，异菌脲、氯氟氰菊酯和氯氰菊酯在几乎所有基质中都表现出更大的基质效应（>150%）。在大多数样品中，采用MC获得的农药回收率与100%回收率在统计学上没有差异，这表明MC可能减少了GC分析中由于基质效应导致的高估。
