Bu çalışmanın amacı, limon meyvelerinin yetiştirilmesi sırasında üzerlerine uygulanan bazı insektisit (abamectin, buprofezin ve etoxazole) kalıntılarının değerlendirilmesi ve soyma, reçel üretimi, dondurma ve depolama gibi evde yapılan işlemlerinin kalıntılar üzerindeki etkisinin araştırılmasıdır. QuEChERS (Hızlı, Kolay, Ucuz, Verimli, Sağlam ve Güvenli) prosedürüne ve üçlü kuadropol sıvı kromatografi kütle spektrometresine dayalı bir çoklu kalıntı analiz yöntemi kullanılmıştır. Ortalama geri kazanım (gerçekliğin bir ölçüsü olarak; %70-120), kesinlik (tekrarlanabilirlik ve ara kesinlik bağıl standart sapma <%20 olarak) ve yöntemin ölçüm limiti (0.01 mg/kg < MRLs) uluslararası kılavuzda belirlenen kriterlere uygun olarak elde edilmiştir. Nisan 2018’de Bursa marketlerinden limon örnekleri satın alınmıştır. Deneysel çalışmalar ve istatiksel değerlendirmeler 5 Mayıs 2018-30 Temmuz 2022 tarihleri arasında Bursa Uludağ Üniversitesi Ziraat Fakültesi'nde (Bursa-Türkiye) gerçekleştirilmiştir. Elde edilen sonuçlara göre, pestisit kalıntısının çoğunlukla meyvenin kabukları üzerinde dağıldığı, dolayısıyla soyma aşamasının meyvenin posasındaki kalıntı miktarını %90-100 oranında azalttığı gözlenmiştir. Meyve suyu ve reçel üretimini içeren işleme adımları nihai üründe kalıntı seviyesini %87-100 oranında azaltmıştır. Sonuç olarak işleme faktörleri (Pf), meyve suyu ve reçel işleme için 1'den küçük olarak, meyve kabuklarının ayrılması, rendelenmesi, dondurulması ve saklanması için ise 1'den büyük olarak elde edilmiştir.

Assessing residues of some insecticides during household processing of lemon

Öz

The goal of this study was to assess the residues of some insecticides (abamectin, buprofezin, etoxazole) applied on the lemon fruits during its cultivation and to investigate the consequence of household processing such as peeling, jam production, freezing and storage on the residues. A multi-residual analysis method based on QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) procedure and liquid chromatography coupled with triple quadrupole mass spectrometry was used. Mean recovery (measure of trueness; 70-120%), precision (as repeatability and interim precision relative standard deviation <20%) and limit of quantification (0.01 mg/kg < MRLs) were in accordance with the criteria set in the international guideline. Lemon samples were purchased from Bursa markets in April 2018. The experimental studies and statistical evaluations were conducted at Bursa University Agriculture Faculty (Bursa -Türkiye) between 5 May 2018-30 July 2022. The results revealed that pesticide residues mostly dispersed on the peel, therefore, peeling step decreased the residue level by 90-100% in the pulp of the fruit. Fruit juice and jam production operations decreased the residue level by 87- 100%. Processing factors were less than 1 for fruit juice and jam processing, on the other hand, it was greater than 1 for the separation, grating, freezing and storage of the peels.
