Abstract
The paper studies determination method of organochlorine pesticides and related chemicals multi-residues in the straw.Multi-organochlorine pesticides and related chemicals residues in the straw were determined by GC-MS equipped with a high performance capillary column chromatography,selected ion scan MS qualitative and quantitative.The straw samples were extracted by fast homogeneous,then were cleaned with SPE.The good linearities were obtained for 18 organochlorine pesticides and related chemicals in the range of 0.005~0.8μg/ml.The correlation coefficient of standard curves was from 0.9987 to 0.9973.The limits of detection were from 0.0008 to 0.008mg/kg.The average recoveries for those pesticide residues in straw were from 76.09 to 106.68%(n=5) at three spiked levels,the relative standard deviations(RSD) were 1.57~9.11%.关键词
