The Use of Radiotracer Techniques for QA/QC Principles in Pesticide Residue Analysis

Abstract

In the process of Turkish Republic being an EU member, wholesomeness of agricultural products is very important at the pesticide residue concept. The reliability of analytical data produced in the pesticide residue laboratory, and validity of method must be checked with documented evidence. Quality Assurance QA and Quality Control QC principles are very useful tools for the proving correctness of analytical data. Most of the analytical steps must be controlled in QA/QC system. The purpose of the article reported here was to demonstrate the use of radiotracer technique 14C-pesticide for some analytical steps such as, the purity/purification of active ingredient, homogenity of sample processing, extraction efficiency bound residues cleanup and recovery in QA/QC system

Keywords

• C-pesticide,radiotracer technique,quality control/quality assurance

Pestisit Kalıntı Analizlerinde Kalite Kontrol ve Kalite Güvencesi Prensipleri İçin Radyoizotop İzleme Tekniğinin Kullanımı

Öz

Avrupa Birliği’ne girme sürecinde olduğumuz şu günlerde tarımsal ürünlerin pestisit kalıntıları yönünden güvenilir olması çok önemlidir. Pestisit kalıntı analiz laboratuvarlarında elde edilen verilerin doğruluğunun ve analiz metodunun geçerliliğinin dokumente edilen delillerle ispatlanması gerekir. Kalite kontrol QC ve kalite güvencesi QA sistemleri analitik verilerin doğruluğunu kontrol etmede önemli bir araçtır. Bu makalenin amacı QC/QA sisteminde, pestisit etkili madde e.m. saflığı/saflaştırılması, örnek işlemenin homojenliği, ekstraksiyon verimi bağlı kalıntılar , temizleme-arıtma cleanup , geri alım recovery gibi analitik işlemlerde radyoizotop izleme tekniğinin 14C-pestisit kullanılmasını göstermektir

Anahtar Kelimeler

• C-pestisit,radyoizotop izleme,kalite kontrol/kalite güvencesi
