In soil and carrot samples collected in the frame of this research from the same carrot beds in the rural community of Aramus, residual DDT and its isomers p,p′- DDT, p,p′-DDD, o,p′-DDT and p,p′-DDE were detected. In all soil samples, the total concentration of DDT exceeded maximum allowable concentration (MAC). In carrot samples, three isomers out of four were detected: p,p′-DDT, o,p′-DDT and p,p′-DDE, the total concentrations of which did not exceed MAC. The DDT/DDE ratio has indicated that the detected concentrations of DDT are due to historical usage of these pesticides. The bioconcentration factor (BCF) values vary in the range of 0.02-0.37.
