Monitoring and Exposure Assessment of Pesticide Residues in Domestic Agricultural Products

Abstract

This study was implemented to evaluate food safety on residual pesticides in agricultural products of Korea and to use as a data base for the establishment of food policy. A total of 196 pesticide upon these products were analyzed using multi class pesticide multiresidue methods of Korean Food Code, and 232 samples of 15 agricultural products collected from 9 regions were supplied for this study. In the results, 64 kinds of pesticides were detected in 53 samples, chlorpyrifos and procymidone of them were shown a high frequency of detection in the analyzed pesticides. Among them, two samples (chlorpyrifos in perilla leaves and picoxystrobin in peach) were detected over Maximum Residue Limits (MRLs). The levels of the detected pesticide residues were within safe levels. Also, the intake assessment for pesticide residues including chlorpyrifos at multi pesticide residue monitoring were carried out. The result showed that the ratio of EDI (estimated daily intake) to ADI (acceptable daily intake) was 0.001~0.902% which means that the detected pesticide residues were in a safe range so that residual pesticides in the agricultural products in Korea are properly controlled.

Degradation kinetics and physiological studies of organophosphates degrading microorganisms for soil bioremediation

“…This is attributed to their profound efficacies in managing crop pests among farmers (Arjmandi et al 2010). Yet, accumulation of these OPs have been apparent in crop fields at unnaturally high concentrations predisposing crop and crop products to residue accumulation (Kang et al 2015). In addition, the chemical class has been reported as the most toxic substance and habitually associated with endocrine disruption (Aguilar-Garduño et al 2013), cancer (Catherine et al 2016) and hypospadias (Michalis et al 2014), nervous disorders (Lee et al 2021) following exposure.…”
