Summary: This article provides a comprehensive assessment of the present-day total mercury mass balance in the Arctic. The majority of mercury is transported to the Arctic via air and ocean transport, and the deposition mainly occurs in terrestrial ecosystems, particularly in soils. Rivers and coastal erosion transfer a significant amount of terrestrial mercury to the Arctic Ocean, in approximate balance with net terrestrial mercury deposition. The revised Arctic Ocean mercury mass balance suggests that the deposition to the ocean and mercury burial in inner-shelf sediments are underestimated, calling for the need for seasonal observations.

Summary: This study aims to measure the combined serum dioxin-like activity of lipophilic persistent organic pollutants (lipPOPs) in Greenlandic Inuit pregnant women and investigate the associations with fetal growth indices. The findings indicate significant dioxin-like activity in the serum samples, which is positively correlated with marine food intake and negatively correlated with body mass index and parity. Furthermore, higher dioxin-like activity is observed in women giving birth to infants with low birth weight and length, as well as in previous smokers.

Summary: This study examines the possible associations between maternal Persistent Organic Pollutants (POP) exposure, maternal hormone levels, and fetal growth indices (FGI). Lipophilic POP exposure was inversely associated with androgen and estrogen levels, but not strongly associated with thyroid hormones. Higher levels of perfluorinated-alkyl-acid (PFAA) were associated with higher thyroid and androgen levels. The thyroid-peroxidase-antibody (TPO-Ab) and estradiol levels were associated with birth weight and length in sons, but inversely associated with birth weight and length in daughters.

Summary: Exposure to legacy and emerging persistent organic pollutants (POPs) poses a significant threat to individual health, with implications for neurodevelopment, endocrine function, and cardiovascular homeostasis. Although the association between traditional air pollutants, exercise, and lung function has been extensively studied, there is a lack of reviews on the relationship between POPs and exercise. This literature review examines the impact of exercise on exposure to POPs, health risk assessment, and the redistribution, metabolism, and excretion of POPs in the body. The review highlights the various benefits of exercise, such as improved insulin sensitivity, mitochondrial DNA repair, lipid metabolism, and intestinal microecological balance. Furthermore, individual lipid metabolism status plays a crucial role in evaluating the potential link between exercise, POPs, and health effects.

Summary: Persistent organic pollutants (POPs) are chemicals that have stayed in the environment for a long time due to their long half-lives. The unsustainable management of chemicals has caused widespread contamination of biota, leading to the recognition of POPs' risk to organisms and the environment. Among the various techniques for removing POPs, microbial bioremediation has been found to be efficient and cost-effective. This review discusses the characteristics of POPs, compares conventional elimination methods with bioremediation, and highlights the potential of microbes as an eco-friendly approach for POPs elimination.

Summary: This study found that adult mice prenatally exposed to the environmental pollutant methylmercury (MeHg) exhibited characteristics of autism spectrum disorder (ASD). The researchers discovered that prenatal MeHg exposure caused premature neuronal differentiation in the embryonic cortex, leading to ASD-like behaviors in the adult mice. Further analysis revealed that MeHg exposure increased CREB phosphorylation and enhanced the interaction between CREB and CREB binding protein (CBP) in cortical radial glial precursors (RGPs). Interestingly, the FDA-approved drug metformin was able to reverse MeHg-induced premature neuronal differentiation through CREB/CBP repulsion.
