Transformation of the Polychlorinated Dibenzo-p-Dioxin and Dibenzofuran Congener Profile during Bioaccumulation in Free-Range Chicken Eggs

Transformation of the Polychlorinated Dibenzo-p-Dioxin and Dibenzofuran Congener Profile during Bioaccumulation in Free-Range Chicken Eggs

The PCDD/F profiles in free-range chicken eggs and the corresponding soils from private households in Vietnam were compared. The main trend in the change in the profile of PCDD/F congeners during bioaccumulation in eggs is a relative increase in the contributions of low-chlorinated congeners and a d...

Description
Summary:The PCDD/F profiles in free-range chicken eggs and the corresponding soils from private households in Vietnam were compared. The main trend in the change in the profile of PCDD/F congeners during bioaccumulation in eggs is a relative increase in the contributions of low-chlorinated congeners and a decrease in the contribution of OCDD. Differences in the profile of hexachlorinated congeners in eggs and soil may indicate additional sources of PCDD/F in eggs other than the soil.
