Summary: Persistent organic pollutants (POPs) accumulated in the body may be associated with the incidence of certain diseases. This study investigated the association between the concentration of POPs and circulating metabolites in human blood samples. The findings suggest that metabolites related to short-chain fatty acids and creatine can be useful risk indicators for estimating the effect of PCB exposure.

Summary: The study collected samples from the habitat and research center of the Qinling panda to assess organochlorine compound contamination. The results show that moderate sources of OC pollution are currently present, with lower levels in samples from nature reserve compared to those collected from captive pandas. Additionally, the study suggests long-range atmospheric transport of pollutants and highlights the importance of transboundary cooperation to safeguard biodiversity.

Summary: This study investigated the spatial trends of legacy halogenated organic pollutants in an urban estuary area. The results showed that urban stormwater and treated wastewater were major sources of these pollutants, which pose potential ecological risks. The study also found that past usage and historic contamination could re-enter surface water through atmospheric transport and deposition. This study provides new insights into the presence, sources, and transport of these pollutants in urban estuaries.

Summary: The study "Residue levels and spatio-temporal distribution of pesticides in different farmland-river interlaced areas of Baiyang Lake" investigated the residue levels and distribution of typical pesticides in soils and waters in different farmland-river interlaced areas of Baiyang Lake. The results showed that thiamethoxam was the dominant pesticide component with high residues in both water and soil. Although most pesticides did not pose a risk to aquatic organisms, carbendazim and propionazole should be paid attention to.

Summary: Turkey's unique location allows it to receive air masses from Europe, Russia, Middle East, and Africa, making it a significant site for long-range atmospheric transport (LRT) of contaminants. Measurements in Istanbul and Izmir showed high levels of organochlorine pesticides, PCBs, and PBDEs, with DDT and HCH derivatives being dominant species. Temperature dependence indicates contributions from both LRT and local contaminated areas to elevated pollutant levels, with potential source regions identified in Africa, Middle East, Europe, and local metropolitan areas.

Summary: The study found that bull sharks were more contaminated than tiger sharks, possibly due to their reliance on coastal habitats for feeding, while tiger sharks had lower contamination levels. The transfer of organic contaminants from mother to embryos differed between the two shark species, indicating that the mode of gestation in sharks may affect maternal transfer.

Summary: Many South African estuaries are impacted by pollutants from industrial and agricultural runoff, sewage outfalls, contaminated storm water drainage, informal settlements, and plastic marine debris, leading to elevated levels of persistent organic pollutants (POPs). Research has shown that some estuaries exceed health advisory levels for chemicals such as PCBs and PFASs, highlighting the need for improved monitoring and government policies to prevent further contamination and protect ecosystem services.

Summary: The objective of this study was to investigate the long-range atmospheric transport of selected POPs released as a result of military conflicts in the south of Turkey's borders. The study found that there was a decreasing trend in concentration with increasing distance from the border. Furthermore, the analysis indicated that the transport of these pollutants mainly originated from Europe, Russia, former Soviet Union countries, and North Africa, rather than the conflict areas.

Summary: Passive air samples were collected in Ny-Alesund and London Island in the Arctic annually for seven years to investigate concentrations of persistent organic pollutants (POPs). The study found declining trends in most POPs, with 3,3'-dichlorobiphenyl (PCB-11) being prevalent. Long-range atmospheric transport was identified as the main factor influencing the distribution of POPs in the Arctic atmosphere, with minor impact from human activities at research stations.

Summary: This study investigated the association between individual and combined exposure to PCBs and OCPs and the risk of metabolic syndrome (MetS) in Wuhan, China. The results showed that PCBs and OCPs were commonly detected in the samples and were positively correlated with increased odds of MetS. Furthermore, the mixture of PCBs and OCPs, with p,p'-DDE being the largest contributor, was also associated with the risk of MetS.

Summary: There is an increasing awareness of paints and pigments as a source of by-product PCBs in the environment. This review identified the presence of 149 different PCBs in paint samples, which is more than what has been reported in commercial Aroclor formulations. The study also provides valuable information on the mechanisms of PCB formation in pigments, dyes, and paints, as well as additional classes of pigments that are expected to contain PCBs.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
