Summary: The study analyzed levels of chlorinated paraffins in human milk samples from 53 countries, with CPs detected in all samples at concentrations of 23-700 ng/g lipid, accounting for 18-46% of total POPs. CP concentrations exceeded PCB concentrations in most countries, emphasizing the need for regulation and research on health effects related to CPs.

Summary: The present study investigated the concentrations and patterns of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in seven species of freshwater food products collected from aquaculture farms in Changsha, China. The results showed that these food products contained high levels of OCPs and PCBs, and consumption of these products posed a carcinogenic risk.

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 thoroughly investigates the relationship between benthos and persistent organic pollutants (POPs), finding that Ephemeroptera samples generally have higher concentrations of pollutants compared to sediment samples, while Trichoptera samples only have higher concentrations in certain POPs. Benthos samples are found to be valuable indicators of contamination, with sediment samples providing complementary information about the recency of contamination.

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: 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: The study presented the baseline levels, inventories, and risk assessment of PCBs and OCPs in surface sediment of the Doce River mouth before the rupture of the Fundao Dam. Results showed a low potential of PCBs and OCPs accumulation before the dam failure, with the decrease of Doce River flow being a main factor contributing to seasonal variations.

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: This study analyzed the distribution of plasma concentrations of 59 POPs in residents of the Canary Islands, comparing data from different time periods. The results showed a variety of POPs detected in the study participants, with some experiencing decreases in concentration levels but others still exhibiting high levels of contamination.

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 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: Seafood consumption is more frequent among Asians compared to other ethnic groups in the U.S., but there is little information about how culturally specific fish consumption contributes to exposure to toxicants. This study surveyed fish consumption among Chinese, Korean, and Vietnamese communities in Chicago and analyzed 103 seafood samples for mercury and organic chemicals. The research found that certain types of fish, such as bluefish, pike, and tuna steak, had high mercury levels, while octopus, shrimp, and tilapia were the least contaminated. Omega-3 fatty acids were more associated with organic contaminants than mercury. Consumption limitations were identified for seven types of fish based on risk assessment.

Summary: The study examined levels of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in moss and topsoil samples across Serbia, finding that moss contamination was mainly due to atmospheric long-range transport.

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: This study analyzed the accumulation and distribution of OCPs and PCBs in the An Hoa Estuary, Central Vietnam, and found the ecological risk to range from low to moderate levels. Furthermore, genetic factors in the form of N-acetyltransferase system phenotype were also analyzed, revealing significant variations among residents in the region, with slow acetylator phenotype prevalent in certain locations.
