QuEChERS yöntemi ile Troia tarım alanları topraklarında insektisit kalıntılarının belirlenmesi

Extensive and misuse of pesticides can cause to toxicity humans pollution in the environment. The primary objective this study was determine insecticide load agricultural soils Troia, located Troia National Park Çanakkale Province (Türkiye) by QuEChERS method. For method verification, blank soil samples were spiked at two levels pesticides. overall recovery 84.8% with a relative standard deviation 13.0% (n = 230), values within acceptable (60-140%) repeatability (≤20%) ranges set SANTE. Forty-nine collected area 2020. Thirty-six had residues varying concentrations. Overall, 23 detected different frequencies. most frequent were: chlorantraniliprole> imidacloprid> pyridaben> clothianidin> indoxacarb (in decreasing order). Mean concentration varied between 0.99-77.7 µg/kg. Imidacloprid all fields, except cabbage fields. highest imidacloprid (23.3 µg/kg) pepper 21 mean 6.20 Persistent insecticides long half-lives, such as chlorantraniliprole, imidacloprid, clothianidin, almost samples.
