Abstract 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.

Abstract A new multiresidue method was developed for the analysis of 19 organochlorine pesticides and 6 polychlorinated biphenyls in yogurt. The sample was extracted twice with acetone by homogenization with an Ultra-Turrax dispersing unit, and the combined extracts were filtered. The extract was then purified by reversed-phase C18 columns and subjected to further cleanup with neutral alumina columns. The residues were determined by gas chromatography with electron capture detection. After the method was optimized, it was validated by determination of recovery percentages, precision (repeatability and reproducibility), and sensitivity (detection and quantitation limits) with yogurt samples fortified at 10 and 1 μg/kg concentration levels. The recovery of 23 organochlorine residues ranged from 77 to 95% at a level of 10 μg/kg, from 74 to 102% at a level of 1 μg/kg, and between 54 and 61% for dieldrin and α-endosulfan. The method is repeatable and reproducible, with relative standard deviation values <19% for all residues except dieldrin. Detection and quantitation limits were between 0.02 and 0.62 μg/kg. The analytical method proposed was quick, accurate, repeatable, and reproducible for the determination of organochlorine residues in yogurt samples.

Abstract Groundwater samples of Ile-Ife, Osun State, Nigeria were investigated for their organochlorine pesticides (OCPs) levels. Probable sources of the OCPs and health risks associated with their consumption along with the water were determined in order to establish the potability of the groundwater samples. Quantitative determination of the OCPs was carried out by Gas Chromatography coupled with Electron Capture Detector (GC-ECD) after liquid-liquid extraction with dichloromethane (DCM). Results indicated that all the analyzed OCPs except p,p'-dichlorodiphenylethane were detected with high concentrations in the groundwater. Heptachlor (14.60±3.60 µg L-1) and methoxychlor (12.60±2.20 µg L-1) showed dominant concentrations that were higher than 0.02 ng L-1 maximum residue levels (MRLs) recommended by the European Union. Levels of the OCPs in the samples followed the decreasing trend: cyclodienes > diclorophehylethanes > chlorinated cyclohexanes, while the predominant source of the analyzed pesticides could be ascribed to aerial transportation from fresh applications in homes within the community. The carcinogenic health risk assessment also revealed consistent higher values of HQ and CR in children as opposed to adults, indicating that children are the more vulnerable population to the analyzed environmental contaminants.

Determination of polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) in water samples from Jabodetabek urban area was conducted. In the results, a unique pattern were found interestingly in Ciliwung river, Pluit, Jakarta, where decachlorinated biphenyl (PCB IUPAC #209), and dichlorinated biphenyl (PCB IUPAC #11) were detected at relatively high concentrations as 406.77 ng/L and 6.38 ng/L, respectively. This congener pattern is different with commercial PCB mixtures, such as arochlor, kanechlor, or chlophen. Octachlorinated dibenzo-p-furan (OCDF) was also detected at a significant concentration in this water as 3.10 ng/L. Decachlorinated biphenyl (PCB IUPAC #209) and OCDF were associated with industrial by-products. Meanwhile, dichlorinated biphenyl (PCB IUPAC #11) was associated with colour pigment which widely used in consumer goods, such as paint and printed ink. Thus, PCBs and PCDD/Fs contamination might have arisen from industrial by-products where various industries located near sampling point. Keywords: polychlorinated biphenyls (PCBs), polychlorinated dibenzodioxins /polychlorinated dibenzo-p-furans (PCDDs/Fs), waters, Jabodetabek, industrial by-products.
