Abstract

Abstract: Home produced eggs from 62 addresses in the Netherlands were investigated for the levels of polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/Fs) and biphenyls (PCBs), both dioxin-like (dl) and non-dioxin-like (ndl). Compared to commercial eggs, levels were relatively high with a median of 4.6 pg TEQ g −1 fat for the sum of PCDD/Fs and dl-PCBs, and a highest level of 18.9 pg TEQ g −1 fat. A number of samples showed clearly elevated ndl-PCB levels with a median of 13 ng g −1 fat and a highest level of 80 ng g −1 fat. There were no clear regional differences, even though part of the samples were derived from the rather industrial Rotterdam/Rijnmond area. Based on the congener patterns, former backyard burning of waste seems the most likely source for most eggs, with two exceptions where other sources contributed to the contamination. Similar is true for the ndl-PCBs. The study shows that average levels are about ten-fold higher than commercial eggs and may substantially contribute to the intake of PCDD/Fs and dl-PCBs by consumers. Intervention measures to reduce the intake of these contaminants by laying hens are advised. Graphical abstract: Highlights: Home produced eggs frequently contain high levels of dioxins and PCBs. Patterns and locations indicate backyard burning as the major source. Certain eggs may contribute substantially to the exposure to dioxins and PCBs. Measures should be taken to reduce intake of contaminated soil by hens.
