Summary: The drinking water supplied to one third of households in Ronneby, southern Sweden was highly contaminated by PFAS, with residents showing significantly elevated serum PFAS levels in comparison to a reference group. PFHxS, PFOS, and PFOA levels were much higher in the residents, with age and gender influencing the serum PFAS levels.

Summary: Perfluorinated compounds (PFCs) are a class of new persistent organic pollutants widely found in the environment. This study examined the effects of two typical PFCs, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), on the composition and diversity of soil microorganisms and the availability of soil macronutrients in urban forest ecosystems. The results showed that PFOA and PFOS application significantly increased soil nitrate and ammonium content, while total phosphorus content remained unchanged. Total potassium content decreased in PFOA treatments but increased in PFOS and PFOA-PFOS combined treatments. The dominant bacterial phylum shifted from Chloroflexi to Acidobacteria with increasing PFCs concentrations. Fungal community composition did not change significantly in response to PFCs treatments. Soil bacterial richness decreased but diversity increased, while fungal richness and diversity generally decreased with increasing PFCs concentrations. Soil fungal community was found to be more sensitive to PFCs pollutants than bacterial communities. Structural equation modeling revealed that PFCs exposure indirectly affected the diversity and richness of soil bacteria and fungi by directly impacting nitrate and ammonium content. The concentration of PFCs pollutants played a primary role in determining the composition, richness, and diversity of forest soil microbial communities.

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: This longitudinal study finds a declining trend in serum PFAS concentrations among firefighters after cessation of exposure to PFAS-containing foams. The main contaminants identified are PFOS, PFHxS, and PFOA. Firefighters under the age of 55, those who used PFAS in the past ten years, or those who had little to no frequency of PFAS exposure in their previous employment experienced a higher annual percentage reduction in serum PFAS concentrations.

Summary: The study found significant regional differences in maternal exposure to PFAS along the Yangtze River, influenced by factors such as per capita consumption expenditure and local production processes of PFASs. The transplacental transfer efficiencies of PFAS isomers decreased significantly with increasing concentrations in maternal serum.

Summary: This study provides insights into how PFAAs modulate the Ppar signaling pathway through the activation of gmPpara1, and suggests that binary exposures have similar effects on gmPpara1, gmPpara2, and gmPparb.

Summary: Per- and polyfluoroalkyl substances (PFAS) have been found to be associated with adverse health outcomes in pregnant mothers and infants, and can be transferred from mother to fetus through the placenta. A systematic review identified 35 studies that evaluated determinants of PFAS concentrations in maternal and neonatal blood. Factors such as parity, breastfeeding history, maternal race and country of origin, and household income were found to be strong and consistent determinants of PFAS concentrations in pregnant mothers. Factors like smoking status, alcohol consumption, and pre-pregnancy BMI were not found to be important determinants. Further research is needed on factors such as consumer product use, detailed dietary information, and consumed water sources.

Summary: PFAS have contaminated land and water worldwide, requiring remediation through sorption. It is important that spent sorbents loaded with PFAS are disposed of properly to prevent release of contaminants. The sorption and desorption processes of PFAS on engineered sorbents are complex and influenced by various factors.

Summary: This research focused on the relationship between soil porewater concentrations and soil concentrations of PFAS, based on a comprehensive model. The model was validated using measured parameters and literature data, showing accurate predictions of concentration ratios. Numerical simulations demonstrated the importance of air-water interfacial adsorption for the distribution of longer-chain PFAS. It was found that PFAS soil porewater concentrations can vary from ng/L to mg/L depending on soil concentrations and site conditions.

Summary: Endocrine disruptors are chemical compounds that cause hormonal imbalance in the body even at low concentrations, leading to various harmful health disorders. PFASs, particularly long- and short-chain variants, have gained significant attention due to their long-lasting presence in the human body and environment, potentially causing short- and long-term health effects.

Summary: Through comprehensive bioinformatics analysis, the correlation between five perfluorinated compounds (PFCs) and prostate cancer was discovered, and the promotive role of perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA) in the growth of prostate cancer cells was verified. This study provided novel insights into the role of PFCs in prostate cancer and raised attention to the environmental association with cancer risks and progression.

Summary: This study compares global breast milk and infant formula PFAS measurements with children's drinking water screening values. It finds that concentrations of PFOA and PFOS in breast milk often exceed these values, regardless of geographic location. This highlights the importance of providing pregnant and lactating women, especially those from PFAS-contaminated communities, with the necessary data to make informed decisions on infant nutrition.

Summary: Plasma and ear notch samples were taken from Holstein cows and heifers to study the accumulation of PFAS. Shorter PFAS did not accumulate in plasma or skin, while longer PFAS accumulated in both. It took at least 1 year of exposure for PFAS to reach steady-state concentrations in plasma. Lactation status had a significant effect on PFAS concentrations in ear notch samples.

Summary: The study conducted urine samples testing on pregnant women in Charleston, SC, discovering that the DINCH metabolite OH-MINCH was detected in 98% of samples, with concentrations significantly higher in African American women compared to Caucasian women. In vitro assays showed that DINCH metabolites did not exhibit estrogenic or progestogenic activity, suggesting the need for continued monitoring of human exposure to these emerging compounds.
