Summary: This study investigated the levels of PCDD/Fs and dl-PCBs in the serum of residents in two urban-industrial zones near and far from an energy recovery plant in Gipuzkoa, Spain. Serum samples were collected from 227 participants and analyzed to determine the concentrations of these compounds. The study found that age, sex, lifestyle factors, and diet were associated with the variability of the measured compounds in the participants' serum.

Summary: This study reports the levels of harmful substances in female e-waste recyclers in Vietnam. The results show that the recyclers have higher exposure levels compared to non-recyclers and the National Health and Nutrition Examination Surveys. Remediation measures are needed to reduce the workers' exposure.

Summary: A waste-to-energy incinerator in Turin, Italy was studied for its potential health effects on the nearby population, with results showing no impact on human exposure to environmental contaminants. After three years, both groups of subjects showed a significant decrease in serum concentrations of analytes compared to baseline, with farmers exhibiting higher levels of contaminants than the general adult population.

Summary: The study found that in a group of 8-9 year old Russian boys, serum dioxins, furans and PCBs clustered by chlorination pattern, with Sigma NDL-PCBs representing 4,4'-chlorinated PCBs most effectively. This may reflect shared persistence, metabolism or source of exposure of these chemicals in the human body.

Summary: In Belgium, 16 shredding facilities manage annually tens of thousands tons of wastes from different origins, containing hazardous persistent organic pollutants. The study found high concentrations of PCDD/Fs, PCBs, and PBDEs in the fallout dust near these facilities, raising concerns about the health effects on workers and residents.

Summary: This study longitudinally explores the public healthcare costs associated with long-term exposure to a mixture of 8 persistent organic pollutants (POPs) in residents of two areas in Granada Province, Southern Spain. The results suggest that long-term exposure to these pollutants may increase healthcare costs and impact the efficiency of healthcare systems. However, further research is needed to determine whether interventions to reduce human exposure should be considered in healthcare policies, due to the limitations of the study.

Summary: This study found lower levels of selected persistent organic pollutants (POPs) in the serum of women from Northern Norway, with concentrations of dioxins, polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), and chlorinated paraffins showing decreasing trends over the studied period. However, medium chain chlorinated paraffins exhibited an increasing trend, raising concerns about their emerging contamination impact on humans. Further global observational studies with larger sample sizes on chlorinated paraffins are needed to validate these findings.

Summary: PCB contamination in China shows regional disparities, with higher levels in East China and in areas with intensive industrial activities or e-waste disassembling. The unplanned UP-PCBs from industrial processes are becoming increasingly significant. There is a need for further studies on the accumulation and migration of PCBs in food webs, and for more investigations to assess human health risks accurately.

Summary: This study aimed to estimate past exposure levels of PCBs, specifically PCB 28, 52, and 101, even years after exposure cessation. Using biomonitoring data from the German HELPcB cohort, PCB 66, 74, and 99 were identified as suitable proxies for the target congeners, with successful validation through correlation coefficients and ICC3 measurements.

Summary: PCBs, despite being restricted in the 1970s, remain hazardous contaminants due to their bioaccumulative and persistent nature. Remediation of historically contaminated matrices is challenging and requires a combination of different techniques and approaches.

Summary: Polychlorinated dibenzo-p-dioxins and furans (PCDD/F) are highly toxic compounds that are difficult to degrade in the environment. This study focuses on the PCDD/F contamination in Sydney Harbour Estuary, with the contamination source area in Homebush Bay being one of the most heavily polluted sites in the world. The researchers found evidence of attenuation of the most toxic congener, 2,3,7,8-TCDD, at the source area. They also discovered a significant population of Dehalococcoidia and Dehalobium, which played a role in the microbial dechlorination of PCDD/F.

Summary: This study found that p,p'-DDE was significantly associated with an increased risk of diminished ovarian reserve (DOR), while beta-hexachlorocyclohexane (beta-HCH) was significantly associated with a decreased risk of DOR. Mixture analyses did not detect any interactions between persistent organic pollutants (POPs).

Summary: The study reveals that low-dose exposure to PCB126 disrupts cardiac metabolism, affecting lipid metabolism, amino acid metabolism, and the tricarboxylic acid cycle. The hearts exposed to PCB126 showed increased collagen synthesis, cardiac fibrosis, and perturbed expression of genes related to the TGFβ/PPARγ/MMP-2 signaling pathway.
