ASE 전처리를 이용한 유기인계 잔류농약 분석의 효율성 평가 및채소 시료에의 적용

Abstract

Application of ASE technique for the extraction of organo phosphorous pesticides from vegetables turn out to be optionally useful. QC recoveries of 6 organo phosphorous pesticides were lied on the range of 80-105%. MDLs were 0.028-0.050 mg/Kg. However, those analytes which are not considered as stable to heat were not suitable for ASE extraction. The degradation of these compounds such as dichlovos and diazinone were accelerated under ASE condition - high pressure, high temperature. Organic and non-organic vegetables are collected and residual organo phosphorous pesticides concentration were determined by means of ASE concentration technique. No residual organo phosphorous pesticides were found in the vegetables regardless organics or non-organics. It could be the result of positive effect "sustainable agriculture campaign" to people who work in agricultural field in general.
