摘要: α-Hexachlorocyclohexane (α-HCH) is a chiral organochlorine pesticide that often ubiquitously detected in various environmental matrices and may be absorbed by the human body via food consumption, with serious detriments to health. In this study, enantioselective degradation kinetics residues of α-HCH laying hens were investigated after single dose exposure pesticide, whereas enantioselectivity eggs, droppings, tissues long-term exposure. Meanwhile, montmorillonite (MMT), feed additive high capacity adsorption, was for its ability remove from hens. Most non-brain enantioselectively accumulated (−)-α-HCH, while (+)-α-HCH preferentially brain. The enantiomer fractions (EFs) most gradually decreased, implying continuous depletion After 30 days 31 elimination, concentration e...
