Abstract

Dithiocarbamate pesticides are the second widely used group of pesticides on tomatoes in the European Union countries. The main toxicological concern of this group of pesticides is associated with their conversion to carcinogenic ethylenethiourea after thermal treatments. The analysis of dithiocarbamate pesticides may be complex because of their low solubility in water, unstable and polymeric structure. Therefore, prior to analysis, these pesticides are usually converted into carbon disulfide form through hot acid digestion. In the literature, maneb and thiuramdisulfite are used as reference pesticides in dithiocarbamate analysis due to their high solubility in water. In this study, mancozeb was used as a reference in gas chromatography with mass spectrometry system because it has the highest conversion rates to ethylenethiourea in the agricultural products with its residues by thermal treatments, and it. Results were evaluated by method validation techniques. Results indicated that linear dynamic range was 0.063-6.316 mg/L, percent recovery was %98.5±1.5, precision was %7.7 while the limit of detection and the limit of quantification were 0.013 and 0.043 mg/L, respectively.

Özet

Ditiyokarbamatlı pestisitler, Avrupa Birliği ülkelerinde domateslere sıklıkla uygulanan pestisitler grubunda ikinci sırada yer almaktadır. Bu gruptaki pestisitlerin toksikolojik önemi ısıl uygulamalarla dönüştükleri kanserojenik etilentiyoüre ile ilişkilidir. Ditiyokarbamatlı pestisitlerin sudaki çözünürlüklerinin oldukça düşük olması, kararsız ve polimerik yapıda bulunmaları, doğrudan analiz edilmelerini güçleştirmekte ve bu nedenle bu pestisitler sıcak asit varlığında karbondisülfide dönüştürülerek analiz edilmektedir. Literatürde ditiyokarbamat analizlerinde suda çözünürlüklerinin daha yüksek olması nedeni ile bu gruptan maneb ve thiuramdisülfidin referans pestisitler olarak alındığı belirlenmiştir. Mankozeb, bu grubun en fazla kullanılan ve kalıntısını içeren tarım ürünlerine ısıl işlem uygulanmalarıyla en fazla etilentiyoüreye dönüşüm oranına sahip pestisittir. Bu nedenle bu çalışmada mankozeb referans alınarak kütle spektrometri dedektörlü gaz kromatografisi (GC-MS) sisteminde tanımlanmış ve bazı metot validasyon parametreleri uygulanarak sonuçlar değerlendirilmiştir. Elde edilen verilere göre metodun doğrusal aralığı 0.063-6.316 mg/L, geri kazanımı %98.5±1.5, kesinlik (RSDr) %7.7, tayin ve ölçüm sınırı sırasıyla 0.013 ve 0.043 mg/L olarak belirlenmiştir.
