Organic chlorine pesticide residues in Rize soils

In this study, Organochlorine pesticide residues were analyzed in soil samples collected from agricultural fields in Rize and Artvin. Total of 126 soil samples collected from 20 cm depth were properly extracted, cleaned up, and analyzed by Gas Chromatography(GC) coupled with electron-capture detector(ECD). Aldirin, eldrin, heptachlor, heptachlorepoxide, 2,4 DDT, 4.4 DDD, 2,4 DDD were detected in some samples, and concentrations were ranged from 2.37 ng/g to 630.48 ng/g. Soil pH ranged from 3.7-6.4 showing acidic soil characteristics which may increase the fate and transport of the pesticides to deeper levels of the soil. Thus, further research needs to be done on deeper levels of soil pesticide concentrations.
