“…In laying hens, the bioavailability of CBs 52, 101, 118, 138, 153, and 180 in soil was comparable with the bioavailability of these PCBs in spiked oil. 30 Chlordecone (CLD) was also reported to be equally bioavailable to laying hens in andosol, nitisol, and spiked oil. 31 The conversion of HBCD isomer patterns from diet to bird tissues and eggs was observed in previous laboratory studies.…”

ABSTRACT:The concentrations and enantiomer fractions (EFs) of α-, β-, and γ-hexabromocyclododecanes (HBCDs) were measured in chicken diet sources (soil and chicken feed), home-raised adult chicken (Gallus domesticus) tissues, eggs during incubation, and hatchling chicken tissues. HBCD concentrations were not detected−0.69 ng/g dry weight (dw) and 25.6−48.4 ng/g dw in chicken feed and soil, respectively. HBCDs were detected in all adult chicken tissues, except the brain, at median levels of 13.1−44.0 ng/g lipid weight (lw). The proportions of α-HBCD in total HBCDs increased from 51% in soil to more than 87% in adult chicken tissues. The accumulation ratios (ARs) of α-HBCD from diet to adult chicken tissues were 4.27 for liver, 11.2 for fat, and 7.64−12.9 for other tissues, respectively. The AR and carry-over rate (COR) of α-HBCD from diet to eggs were 22.4 and 0.226, respectively. The concentrations of α-HBCD in hatchling chicken liver (median: 35.4 ng/g lw) were significantly lower than those in hatchling chicken pectoral muscle (median: 130 ng/g lw).The EFs of α-HBCD decreased from soil to adult chicken tissues and from eggs to hatchling chicken liver. Meanwhile, the EFs of γ-HBCD increased from soil to adult chicken tissues. These results indicate the preferential enrichment of (−)-α-HBCD and (+)-γ-HBCD in chickens. The alteration of diastereoisomeric and enantiomeric patterns of HBCDs might be influenced by the different absorption and elimination rates of the six HBCD enantiomers as well as variations in HBCD metabolism in chickens.

“…Moreover, eggs are included in several food products for various functions (Leggli et al, 2010). Independently of the production method, the transfer of POPs into hen eggs, especially into yolk as their bound to egg fat content, has been widely documented for OCPs and other compounds as polychlorobiphenyls (Fournier et al, 2012). For this reason, securing the quality of hen eggs is an important issue for Chronic exposure to POPs was found to interfere with the activity of endogenous hormones in humans, including T4, T3 and TSH (Langer, 2010).…”

| This work is proposed to investigate pesticide residues in chicken eggs in El-Sharkia Province, Egypt. Analysis of pesticide residues was performed on 120 egg samples included 80 random edible egg samples (40 farm and 40 home produced hen eggs) and other 40 unhatched eggs. Edible eggs were collected from different stores, places and supermarkets. unhatched incubated eggs were collected from different hatcheries during the winter season. Organochlorine pesticides (OCPs) and organophophorous insecticides (OPIs) residue analysis of samples was done using Agilent Gas chromatograph (GC) Model 6890 N. The results revealed presence of OPIs in higher concentration in home produced eggs than that in farm produced eggs, while OCPs present in farm produced egg in higher levels than that in home produced one. Unlike other studies we have not found higher levels of exposure for most pesticides in those consumers choose home produced eggs, and even farm produced eggs. Regarding unhatched eggs dimethioate recorded the highest concentration which exceeded Maximum Residual Limits (MRLs) of (0.05) mg/kg in all the examined samples. None of the other detected pesticide residues exceeded (MRLs). It was concluded that the levels of pesticide residues in edible eggs either home or farm produced eggs should not exceed Accepted Daily Intake (ADI) established by the World Health Organization (WHO) Joint Meeting on Pesticide Residues Report ( JMPR). The study suggests the need for further investigations to determine toxic mechanisms by which dimethoate distress chick emberyos at different developmental stages and result in hatching failure.

“…Their presence in food is a result of their affinity to lipids, lack of metabolic changes, and bioaccumulation in tissues, even when their environmental concentrations are low. These compounds are excreted from mammalian organisms during lactation periods, and accumulated in poultry tissues, penetrating into egg yolk along with fat (5,8,18). Hens foraging in freerange paddocks ingest various soil elements together with feed.…”

The paper presents the results of testing eggs for the content of dioxins and polychlorinated biphenyls (PCBs), determination of the sources that caused the presence of high concentrations of these compounds which exceeded the acceptable contamination levels, and assessment of consumer health risk caused by the consumption of eggs with excessive contents of investigated compounds. In about 9% of free range eggs and 17% of organic eggs, the content of PCDD/Fs was two-or threefold higher than the acceptable limits, and in some samples the concentration of investigated compounds exceeded the maximum concentration levels. Based on the profile of the compounds, it was confirmed in several cases that their main source was the soil or unsecured refuse. The consumers of eggs and meat produced under these conditions constitute the risk groups, and their dioxin and PCB intake may exceed toxicological reference values.
