Özet
Amaç: Bu çalışmada, Antalya ilinde yapılan toksikolojik çalışmalarda tespit edilen, yasaklı pestisitlerin güncel kullanımına yönelik bulgulardan hareketle halka açık alanlarda satılan bitki koruma ürünü ve biyosidal ürünlerin bileşiminde yer alan maddelerin nitel olarak belirlenmesi amaçlanmıştır. Yöntemler: Antalya ili genelindeki semt pazarları ve tezgâh altı diye tabir edilen satıcılar ve tarımsal faaliyetlerin yoğun olarak yapıldığı ilçelerden DDT, böcek öldürücü, karınca öldürücü vb. isimle satılan toplam 19 adet numune toplanmıştır. Ürünlerin içeriğinin belirlenmesi amacıyla her birinden 100 mg tartılarak 10 mL metanol içerisinde çözüldükten sonra izooktan ile seyreltilerek Gaz Kromatografisi-Kütle Spektrometresi (Shimadzu QP2010 Ultra) cihazında analizi yapılmıştır. Tarama modunda elde edilen kromatogramlar kapsamlı bir pestisit kütüphanesi olan Wiley/NIST içeriği ile eşleştirilmiştir.Bulgular: Nitel değerlendirme sonucunda örneklerde etken maddesi klorpirifos-etil olan Dursban maddesinin yanı sıra diklorvos, aldicarb ve sipermetrin bulunduğu görülmüştür. Bu etken maddelere ek olarak örneklerde değişik oranlarda sebasik asit, merkaptan, propiyonik asit gibi yardımcı maddeler (dolgu maddeleri) tespit edilmiştir. En fazla tespit edilen etken madde, numunelerin %31,6'sında görülen klorpirifos-etil iken en fazla tespit edilen yardımcı madde sebasik asittir Sonuç: Analiz edilen ürünlerin bazılarının içeriğinde insan sağlığı için tehdit oluşturabilecek ve USEPA tarafından kanserojen olarak sınıflandırılmış maddelerin olduğu veya zararlı canlılara tesir edecek herhangi bir etken madde içermeyen ürünlerin kontrol ve denetimden uzak bir şekilde ticari faaliyetlerde kullanıldığı görülmüştür. Bu tür ürünlerin yeterli bilgi birikimi olmayan kişiler tarafından bilinçsiz şekilde uygulanmasının gerek kullanıcı ve gerekse çevre sağlığı açısından ciddi risk oluşturabileceği düşünülmektedir
Objective: In this study, it was aimed to determine qualitatively the substances in the composition of biocidal products and plant protection sold in public areas with reference to current use of prohibited pesticides detected in toxicological studies conducted in Antalya province. Methods: A total of 19 samples sold under the name of DDT, insecticide, termiticide were gathered from public markets, illegal suppliers and districts where agricultural activities take place in Antalya province. To identify ingredients of products, after 100 mg of each was weighed and dissolved in 10 ml methanol, it was diluted with isooctane, and tested to instrumental analysis on a Gas Chromatography-Mass Spectrometry (Shimadzu QP2010 Ultra). Chromatograms gathered from scan mode were matched with the content of Wiley/NIST which has a comprehensive pesticide library. Results: AAs a result of qualitative evaluation, it was observed that dichlorvos, aldicarb and cypermethrin as well as Dursban whose active ingredient is chlorpyrifosethyl in the samples. In addition to these active ingredients, inactive ingredients (extender) such as sebacic acid, mercaptane, propionic acid were detected at varying ratios in the samples. While chlorpyrifos-ethyl was mostly detected in 31.6% of the active content available, sebacic acid (47.4%) was mostly detected as extender ingredient as well. Conclusion: It has been observed that there are materials that are classified as carcinogenic by USEPA and may pose a threat to human health in the content of some of the products analyzed, or that the products which do not contain any active ingredient affecting incect pests have been used in commercial activities away from control and supervision. It is considered that the unconscious implementation of such products by persons with insufficient knowledge may constitute a serious risk in terms of both user and environment.
