Abstract

Performance of proficiency testing and the validation of analytical method was included a scheme of quality assurance in analytical chemistry laboratory to monitor a laboratory's performance abilities and produce consistently reliable data. This study was assessed the applicability of proficiency testing scheme proposed for analytical laboratories of pesticide product in domestic. The validation of analytical methods, stability and homogeneity for formulated pesticide products (emulsifiable concentrate) of emamectin benzoate and lufenuron was confirmed for the proficiency testing. The z-score of 33 participation laboratories for emamectin benzoate were that the numbers of outlier were 2 laboratories (6.0%), z-score outside the range from -3 to 3 designated "unaccptable" were 2 laboratories and z-score in the ranges -2 to -3 and 2 to 3 designated "questionable" were 3 laboratories (9.0%). Three laboratories (9.0%) showed the z-score designated "questionable" for lufenuron. The additional proficiency testing for various product types will be needed to establish the scheme of quality control.

숙련도시험 수행 및 분석법확립은 분석기관의 지속적인 시험결과에 대한 신뢰성 확보 및 시험기관의 분석능력 관리를 위한 정도관리 체계에 포함되는 항목이다. Emamectin benzoate 및 lufenuron 유제 시료에 대한 분석법 검증, 안정성 및 균질성을 확인한 후, 농약 이화학시험 분석기관(33개 기관)을 대상으로 두 약제에 대한 시료를 배포하여 숙련도시험을 수행하였으며, 분석기관의 수행능력을 z값으로 평가하였다. Emamectin benzoate는 참여기관 총 33개 중 이상값은 2개 기관(6.0%), z값이 |Z| > 3.0 및 |Z| < -3.0 범위을 나타내는 부적합은 2개 기관(6.0%) 및 z값이 -2.0 < |Z| -3.0 및 2.0 < |Z| < 3.0 범위인 검토대상은 3기관(9.0%)이었고, lufenuron에 대한 z값의 범위가 검토대상인 기관은 3개(9.0%)였다. 본 연구는 국내 농약 이화학시험 분석기관에 적합한 정도관리 체계 마련을 위하여 숙련도 시험의 적용가능성을 확인하였으며, 추가적으로 다양한 농약제품에 대한 숙련도시험을 수행하여 보완이 필요하다.
