Plant uptake potential of endosulfan from soil by carrot and spinach

Abstract

Residual endosulfan in an agricultural environment has been reported, although endosulfan was listed to persistent organic pollutants and banned. To produce the safe crop from endosulfan residue risk, the plant uptake potential of endosulfan from soil to crop should be studied. In here, the plant uptake potentials of endosulfan in various crops were surveyed and ranged from 0.002-4.460. And the bioconcentration factors (BCF) of total endosulfan in carrot and spinach were calculated from the pot experiment. The BCFs in carrot and spinach were 0.285 and 0.040-0.047 respectively. Endosulfan sulfate was contributed to over 42.8% of the crop residue as a major contributor among the three endosulfan congeners in both of carrot and spinach. ?
