Summary: This study investigated the association between diet, demographic characteristics, and PFAS exposure levels in early pregnancy. The results showed that high-fat foods such as fish, seafood, and animal offal were significant sources of PFAS, while plant-based foods and drinking bottled water were negatively associated with PFAS concentrations.

Summary: This study evaluated the associations between metabolites in maternal and cord serum and internal exposure to common PFASs. It identified multiple metabolites and pathways linked to PFAS exposure in pregnant women and fetuses, indicating the potential application of metabolome-wide association studies in studying toxic mechanisms of PFASs. Additional research is required to confirm causation.

Summary: This study investigated the association between perfluoroalkyl substances (PFASs) joint exposure and uric acid levels. It found significant associations between individual PFASs exposure, such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA), with uric acid levels and hyperuricemia. However, the joint effect of PFASs mixture on uric acid was not observed. These findings provide new insights into regulation policies and risk assessment of PFASs.

Summary: This study evaluated the toxic potency of PFECHS, an emerging PFAS, on zebrafish embryos and its potential effects in aquatic environments. The results showed that PFECHS caused fewer mortalities than PFOS in both acute and chronic exposures but resulted in a similar incidence of deformities. Exposure to PFECHS also increased the levels of specific genes at concentrations relevant to the environment. These findings provide insights into the safety of emerging PFAS alternatives in the aquatic environment and highlight the potential similarity of effects with legacy PFASs.

Summary: Dietary supplements sourced from marine environments, such as fish oils and seaweed-based supplements, can be a potential source of arsenic exposure. A study found high total arsenic concentrations in supplements made from seaweed, krill, and calanus oil, as well as in unprocessed fish and fish liver products. Inorganic arsenic was detected only in seaweed samples, while arsenic hydrocarbons were found in unprocessed fish and fish liver oil, and calanus oil. Pregnant women who consumed fish oil supplements had higher urinary arsenic concentrations, including arsenobetaine and dimethyl arsenic.

Summary: Perfluoroalkyl substances (PFASs) were investigated in five Baltic fish species. PFOS was found in the highest concentrations and dominated the total PFASs concentration. Different consumption scenarios were assumed and the intake of PFASs was calculated for children and adults. Baltic fish caught along Polish coastal areas are a significant source of PFASs, especially for children.

Summary: Firefighters are at risk of exposure to PFASs, especially from AFFF. They have elevated serum levels of long-chain PFASs. Due to the persistence and bioaccumulation of PFAS chemicals, firefighters experience cumulative effects from AFFF exposure throughout their careers. Studies have shown an elevated risk of various cancers among firefighters due to PFAS exposure, necessitating further research.

Summary: Many first trimester sporadic miscarriages are unexplained, and this study aimed to investigate the association between levels of Perfluoroalkyl substances (PFASs) in early pregnancy with unexplained first trimester miscarriage. The results showed a positive correlation between PFOA exposure and sporadic first trimester miscarriage, while other PFASs showed no significant association with miscarriage. This suggests a potential shared but unknown mechanism between PFOA exposure and miscarriage.

Summary: Previous research in Suriname has found high concentrations of mercury in hair of women and children in rural interior communities, as well as in freshwater fish. Pregnant women from interior communities have significantly higher concentrations of total and methylmercury in hair compared to those from urban coastal cities. Mercury exposures in pregnant women in Suriname are largely influenced by diet and fish consumption, with methylmercury making up the majority of total mercury in both blood and hair.

Summary: Human exposure to chemical mixtures from various sources may pose risks to health, especially during critical periods of development. Traditional one-chemical-at-a-time approaches have limited understanding of the combined effects of mixtures. Researchers are now using in vitro assays to assess exposure and health impacts of chemical mixtures, providing a more comprehensive understanding of their effects on human health.

Summary: European and French populations are overexposed to cadmium through their foods. This study aimed to derive a low and protective cadmium concentration in edible seaweeds to limit overexposure. The research used a probabilistic approach considering other sources of cadmium exposure and identified a cadmium concentration that ensures the seaweed-consuming population does not exceed the tolerable daily intake of cadmium. This generic approach could be applied to other food/substance pairs in setting maximum limits, providing better protection for consumer health.

Summary: This study estimated the burden of disease due to dietary exposure to four chemicals (lead, cadmium, methylmercury, and inorganic arsenic) in France in 2019. It found that inorganic arsenic and lead had the highest disease burden, while methylmercury and cadmium had a lower burden. Drinks, other foods (mostly composite dishes), and fish and seafood were the main contributors to the disease burden.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
