ABSTRACT / SAŽETAK:
Determination of pesticides in red Ajvar pepper (Capsicum annuum cv. Kurtovska Kapija) was performed with the method of QuEChERS (EN 15662). A total of 40 samples of red pepper ajvarka (Kurtovska kapija) from the village of Dabile, Strumica region were analyzed. Identification and quantification of 397 pesticides were performed and imidacloprid was detected above the permitted concentrations (0.011 mg/kg) in samples treated by Nimazal before harvesting, while in the samples of Ajvar red pepper treated with a combination of Dikrsol 500 sp and Proteus, the same pesticide imidacloprid was detected at a concentration of 0.032 mg/kg sample. The permited MDK value for this pesticide is up to a maximum of 0.01 mg/kg.
KEYWORDS / KLJUČNE REČI:
