Abstract
In this research, 203 different pesticides’ residue levels were investigated in 101 pieces of fresh grape and 10 pieces of strawberry which taken from local markets and wholesale markets in Konya City. Sample extraction was performed in Selcuk University Agricultural Faculty Laboratories in departments of both Horticulture and Crop Sciences, while LC-MS/MS and GC-MS analysis were conducted in the Organic Agricultural Products and Residue Analysis Laboratory in Republic of Turkey Ministry of Agriculture and Rural Affairs Izmir Province Control Laboratory. According to conducted results, imazalil was determined at 34 μg/kg, 33 μg/kg and 47 μg/kg levels in three pieces of fresh grape samples that this value is over the limit value given (20 μg/kg) in Turkish Food Codex. Benomyl-Carbendazim was also determined at 337 μg/kg and 433 μg/kg in two pieces of fresh grape samples (limit value was 300 μg/kg). Monocrotophos was determined at 1100 μg/kg in a sample of grape that this value exceeds about 55 times the limit value given (20 μg/kg) in Turkish Food Codex. Acetamipridin pesticide residue, which is completely prohibited, was determined at 4 μg/kg, 30 μg/kg and 37 μg/kg levels in three pieces of fresh grape samples that the limit value given as 10 μg/kg in Turkish Food Codex. In the study, the pesticide residues were not detected in 38% of the total investigated grape samples, 1 type of pesticide residue was determined at 10% of examined grape samples, 2 types of pesticide residues were determined at 20% of examined grape samples, 3 types of pesticide residues were determined at 10% of examined grape samples, 4 types of pesticide residues were determined at 11% of examined grape samples, 5 types of pesticide residues were determined at 9% of examined grape samples, 6 and 7 types of pesticide residues were determined at 2% of examined grape samples. Chlorpyrifos pesticide residue was determined at 5 μg/kg, 11 μg/kg and 10 μg/kg in three strawberry samples. The pesticide residue was not detected in 70% of examined strawberry samples while in the remaining samples, the pesticide levels were found above the limit value and some of these samples contained completely prohibited chemicals.
Özet
Bu araştırma, Konya yöresinde halkın tüketimine sunulan mahalli pazarlar ve marketlerden toplanan 101 adet yaş üzüm ve 10 adet çilek meyvelerinde 203 adet pestisitin kalıntı düzeylerinin belirlenmesine yönelik olarak yapılmıştır. Meyve örneklerinin ekstraksiyon aşamaları Selçuk Üniversitesi Ziraat Fakültesi Bahçe Bitkileri ve Tarla Bitkileri Bölümlerine ait laboratuvarlarda, kalıntı analizleri ise T.C. Tarım ve Köyişleri Bakanlığı, İzmir İl Kontrol Laboratuvar Müdürlüğü’nün Organik Tarım Ürünleri ve Kalıntı Analiz Laboratuvarı’nda LC-MS/MS ve GC-MS cihazlarında yapılmıştır. Araştırmadan elde edilen bulgulara göre, 3 adet yaş üzüm numunesinde 34, 33 ve 47 μg/kg (tolerans değeri 20 μg/kg) düzeylerinde İmazalil, 2 adet yaş üzüm numunesinde 337 ve 433 μg/kg Benomyl-Carbendazim (tolerans değeri 300 μg/kg) bulunmuştur. Bir üzüm numunesinde Monocrotophos kalıntısı 1100 μg/kg olup, Türk Gıda Kodeksi (TGK)’nin limit değeri olan 20 μg/kg seviyesini 55 kat aşmıştır. Ayrıca, 3 yaş üzüm örneğinde kullanımı tamamen yasak olan Acetamipridin (TGK tolerans değeri 10 μg/kg) 4, 30 ve 37 μg/kg düzeylerinde olduğu tespit edilmiştir. Araştırmada ele alınan yaş üzüm numunelerinde pestisit kalıntısına rastlanmayan ürün, toplam ürünün %38’ini, bir adet pestisit kalıntısı bulunan %10’unu, 2 adet pestisit kalıntısı bulunan %20’sini, 3 adet pestisit kalıntısı bulunan %10’unu, 4 adet pestisit kalıntısı bulunan %11’ini, 5 adet pestisit kalıntısı bulunan %9’unu, 6 ve 7 adet pestisit kalıntısı bulunan %2’sini oluşturmuştur. İncelenen 10 adet çilek numunesinin 3 tanesinde ise kullanımı yasak olan Chlorpyrifos’un 5.0, 11.0, 10.0 μg/kg düzeylerinde kalıntısına rastlanmıştır. Çilek numunelerinde, kalıntısız örnek oranı %70, kalıntılı örnek, limit üzerinde kalıntılı örnek ve yasaklı kimyasal kullanılan örnek oranları %30’ar olarak tespit edilmiştir.
