Abstract

Persistent organic polluting pesticides that have been used extensively historically can still be detected in agricultural products and cause health risks. In this study, banned organochlorine pesticide (OCP) residue levels in 23 garlic samples produced in the fields of different villages located in the potentially polluted area in the center of Kastamonu were determined by GC/MS method combined with QuEChERS extraction and clean-up technique. In our study, at least one OCP was detected in 14 of 23 samples and 20 of the 23 OCPs we examined in our study, were detected in at least one sample. The most frequently detected OCP residue in garlic is dichloro-diphenyl-trichloroethane (DDT) and its metabolites. The residue levels of all garlic samples were below their maximum residue levels (MRL), except for sample 16. Eighteen of the OCPs we examined in our study, were determined in sample 16 and 14 of them had very high concentrations. Estimated daily intake levels (EDI) of all samples were calculated to determine whether the acceptable daily intake (ADI) levels were exceeded in order to make a risk assessment. None of the EDI values calculated from the amounts of residues in the sample 16 exceeded the ADI levels. However, it should not be forgotten that samples such as sample 16 may pose a risk of exposure for people whose actual consumption of garlic is higher than the calculated amount.

Sarımsakta Organoklorlu Pestisit Kalıntılarının Tespiti ve Sağlık Risklerinin Değerlendirilmesi

Abstract

Tarihsel olarak yaygın olarak kullanılan kalıcı organik kirletici pestisitler, tarım ürünlerinde hala tespit edilebilmekte ve sağlık risklerine neden olabilmektedir. Bu çalışmada, Kastamonu il merkezinde potansiyel olarak kirlenmiş alanda bulunan farklı köylerin tarlalarında üretilen 23 sarımsak örneğinde yasaklı organoklorlu pestisit (OCP) kalıntı seviyeleri QuEChERS ekstraksiyon ve temizleme tekniği ile kombine GC/MS yöntemi ile belirlenmiştir. Çalışmamızda 23 örneğin 14'ünde en az bir OCP, çalışmamızda incelediğimiz 23 OKP'nin 20'sinde en az bir örnekte OCP saptandı. Sarımsakta en sık saptanan OCP kalıntısı dikloro-difenil-trikloroetan (DDT) ve metabolitleridir. Örnek 16 hariç tüm sarımsak örneklerinin kalıntı seviyeleri maksimum kalıntı seviyelerinin (MRL) altındaydı. Çalışmamızda incelediğimiz OCP'lerin 18'i örnek 16'da belirlendi ve 14 tanesi çok yüksek konsantrasyonlara sahipti. Bir risk değerlendirmesi yapmak için kabul edilebilir günlük alım (ADI) seviyelerinin aşıp aşılmadığını belirlemek için tüm numunelerin tahmini günlük alım seviyeleri (EDI) hesaplandı. Örnek 16'daki kalıntı miktarlarından hesaplanan EDI değerlerinin hiçbiri ADI seviyelerini geçmedi. Ancak, gerçek sarımsak tüketimi hesaplanan miktarın üzerinde olan kişiler için örnek 16 gibi örneklerin maruz kalma riski oluşturabileceği unutulmamalıdır.
