Abstract

Bu çalışma 2022 yılında Aydın ilinde yoğun incir, Ficus carica L. (Rosales: Moraceae) üretiminin yapıldığı lokasyonlardan alınan 92 yaş ve 50 kuru incir numunesinde insektisit, akarisit ve nematisit kalıntılarının tespiti için gerçekleştirilmiştir. Analiz metodu SANTE 11312/2021’e göre doğrulanmıştır. Ortalama geri kazanımlar %73,2 ile %119,6 arasında olup yöntemin tekrarlanabilirliği (RSDr) ve laboratuvar içi tekrar üretilebilirliği (RSDwR) için ≤ %20 ve genişletilmiş ölçüm belirsizlikleri %50'nin altındadır. Bu veriler tatmin edici analitik performansı göstermektedir. Toplamda 114 farklı insektisitin tarandığı çalışmada, 92 yaş incir numunesinin 13’ünde bifenazate, 3’ünde etoxazole, 5’inde spiromesifen, 6’sında ise hem bifenazate hem spiromesifen olmak üzere toplam 27 numunede pestisit kalıntısı kaydedilmiştir. Kuru incir örneklerinde tespit edilebilir kalıntıya rastlanmamıştır. Bifenazate tespit edilen örneklerin tamamı Avrupa Birliği Maksimum Kalıntı Limitlerinin (AB-MRL) üzerindedir. Etoxazole ve spiromesifen etken maddeleri incirde ruhsatsız olup, numunelerde tespit edilen etoxazole kalıntıları AB-MRL üzeri, spiromesifen ise AB-MRL altıdır. Tespit edilen insektisitlerin akut ve kronik sağlık risk indeksi 1'den düşük bulunmuştur. Risk değerlendirmesi incir tüketiminin tüketiciler için güvenli olduğunu göstermiştir.

Investigation of insecticide residues in fig and health risk assessment

Abstract

This study aimed to detect insecticide, acaricide, and nematicide residues in 92 fresh and 50 dried fig samples collected from locations with intensive fig, Ficus carica L. (Rosales: Moraceae) production in Aydın, Türkiye in 2022. The analysis method was validated according to SANTE 11312/2021 guidelines. The recoveries ranged between 70% and 120%, with repeatability (RSDr) and within-laboratory reproducibility (RSDwR) ≤ 20% and expanded measurement uncertainties below 50% for all insecticides indicating satisfactory analytical performance. In total, 114 different insecticides were screened, revealing residues in 27 samples. Bifenazate was detected in 13 samples, etoxazole in 3 samples, spiromesifen in 5 samples, and both bifenazate and spiromesifen in 6 samples. No detectable residues were found in the dried fig samples. All samples in which bifenazate was detected were above the European Union Maximum Residue Limits (EU-MRL). Etoxazole and spiromesifen, unauthorized in figs, showed etoxazole residues above EU-MRLs, while spiromesifen residues were below EU-MRLs. The acute and chronic health risk indices for the insecticides were found to be below 1, indicating low health risks associated with fig consumption. The risk assessment suggests that fig consumption is safe for consumers.
