Summary: Prenatal exposure to certain endocrine-disrupting chemicals, such as perfluorooctanoic acid (PFOA), perfluoro octane sulfonic acid (PFOS), perfluononanoic acid (PFNA), and mono-ethyl phthalate (MEP), is associated with an increased risk of gestational hypertension (GH) and preeclampsia (PE). However, exposure to bisphenol A during pregnancy does not show a significant association with the risk of PE. More research is needed to confirm these findings, as the evidence for most of these associations is limited.

Summary: Hypertensive disorders of pregnancy (HDP), including gestational hypertension (GH) and preeclampsia (PE), are associated with exposure to per- and polyfluoroalkyl substances (PFAS) such as PFOA, PFOS, and PFHxS. Meta-analysis of observational studies revealed an increased risk of PE and HDP with exposure to PFAS. However, caution should be exercised in interpreting these findings due to limitations in the meta-analysis and quality of evidence, and further research is needed to assess multiple PFAS exposures in diverse populations.

Summary: The meta-analysis revealed a potential positive association between maternal exposure to perfluorooctane sulfonic acid (PFOS) and preterm birth, but limited evidence of an association between maternal exposure to perfluorononanoic acid (PFNA) and miscarriage. No significant associations were found between other PFASs and adverse pregnancy outcomes. The results suggest that further studies with larger sample sizes are needed to confirm these findings.

Summary: The analysis of 19 PFASs in umbilical cord serum samples in China revealed that PFOA was detected in all samples, with PFOS having the highest median concentration. Neonatal birth weight was negatively correlated with long-chain PFOS, and concentrations of certain PFASs differed significantly between birth weight groups. Maternal characteristics such as age, education, diet, and nutritional supplementation during pregnancy can affect PFAS exposure in the fetus.

Summary: This study investigated the effects of gestational exposure to PFASs on fetal growth by examining DNA methylation in placenta tissue of pregnant women. The results showed that PFOS was negatively associated with LINE-1 methylation, and the mixture of PFASs was negatively associated with LINE-1 methylation and NR3C1 methylation. PFOA, PFNA, PFDA, and the PFASs mixture were negatively associated with head circumference. Stratified analysis by newborns' sex found that PFOA, PFNA, and the PFASs mixture were negatively associated with LINE-1 methylation in males, and LINE-1 methylation was negatively associated with ponderal index in females. Interactions between newborns' sex and PFOS/PFOA on IGF2 and LINE-1 methylation were statistically significant. These findings suggest that intrauterine exposure to PFASs affects placental DNA methylation and reduces fetal growth, which may be modified by sex.

Summary: This study evaluated the association between maternal exposure to PFASs and macrosomia and LGA. The results showed a U-shaped relationship between maternal PFDA and PFOA exposure and the risks of macrosomia and LGA. A positive association was observed when PFDA and PFOA concentrations exceeded certain thresholds, while a negative association was observed when concentrations were below those thresholds. In mixed exposure models, the PFASs mixture was positively associated with macrosomia and LGA when all PFASs were at their 30th percentile or below.

Summary: PFAS, widely used organic chemicals, are major contributors to environmental pollution due to their stability. Exposure to PFAS has been linked to increased risk of cardiovascular disease, possibly through altering lipid and glucose metabolism, raising blood pressure, and promoting thrombus formation. Studies suggest that PFAS can incorporate into platelet membranes, enhancing platelet functions and potentially contributing to the observed increase in cardiovascular events in populations exposed to PFAS.

Summary: Comprehensive enrichment of contaminants in drinking water is crucial for accurately determining exposure levels and testing biological effects. Traditional methods using a single absorbent may not be sufficient for complex matrices. An integrated enrichment system with three sequential stages was used to capture organic pollutants and disinfection by-products in Shanghai's drinking water. The results showed that a single adsorbent system underestimated the exposure levels of pollutants and the biological effects of organic pollutants.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.
