Summary: Exposure to poly: and perfluoroalkyl substances (PFAS) in early life may increase the risk of childhood asthma, but the associations between maternal serum concentrations of PFAS during pregnancy and clinician-diagnosed asthma incidence in offspring have been inconsistent. In this study, no significant association was found between prenatal PFAS concentrations and the incidence of clinician-diagnosed asthma in children followed to eight years of age.

Summary: This study investigated the association between prenatal and early postnatal PFAS exposure and delayed language development in Danish children aged 18 to 36 months, and found no significant association between PFAS exposure and language development. The study recommends assessing child serum PFAS at an older age, considering the potential positive effect of breastfeeding on neurodevelopment.

Summary: This study investigated the temporal relationship between pre- and postnatal exposure to PM10, PM2.5, NO2, and child cognitive function. The results showed that increased maternal exposure to these air pollutants during mid-pregnancy was associated with lower cognitive abilities in male children. Additionally, higher postnatal exposure to PM2.5 during the age of 3-4 years was also associated with lower cognitive abilities in males. These findings highlight the importance of understanding the impact of air pollution on child cognitive development and identifying sensitive periods.

Summary: This study aimed to evaluate the associations between prenatal perfluoroalkyl substances (PFAS) exposure and neuro-development in toddlers from 1 to 3 years of age. The results showed negative associations between prenatal PFAS concentrations and neurodevelopment measurements at specific ages. In boys, PFOA exposure was negatively associated with DQ z-score, while increased PFBS and PFHpA exposure were associated with elevated odds for the low-score trajectory group.

Summary: Findings from this study suggest that prenatal exposure to multiple PFASs may have some effects on neurobehavioral development in children, but there is no clear evidence of negative effects. However, the modest associations found still suggest the potential developmental neurotoxicity of prenatal PFAS exposure.

Summary: The study found that the concentration of PFAS in source water is relatively low, with a removal rate during treatment of only 11%, and long-chain PFAS have a higher removal rate than short-chain PFAS. Seasonal factors influence the total concentration of PFAS in water, but have a minor impact on the composition characteristics of PFAS. The detected PFAS concentrations in drinking water are within the recommended standards, posing no significant health risks.

Summary: The study found that maternal serum levels of poly- and perfluoroalkyl substances (PFAS) are associated with sex steroid hormone levels during pregnancy. Specifically, PFHxS is associated with increased testosterone levels in male fetuses, while PFNA and PFDA are associated with increased free testosterone levels in male fetuses. For female fetuses, PFHxS is associated with increased levels of estradiol and estriol. No associations were found for PFOS and PFOA.

Summary: The study found that prenatal exposure to background levels of PBDEs, especially BDE-47, was associated with lower IQ scores in boys, but not in girls. This suggests that exposure to PBDEs during early development may have a sex-dependent and detrimental effect on a child's neurodevelopmental trajectory.

Summary: This study found that maternal exposure to organophosphate esters (OPEs) may be associated with increased blood pressure during pregnancy and hypertensive disorders of pregnancy (HDP), particularly with the concentrations of diphenyl phosphate (DPHP) and bis(2-chloroethyl) phosphate (BCEP) showing stronger correlations with elevated blood pressure. Di-n-butyl phosphate (DNBP) concentrations were also associated with HDP, albeit with borderline significance.

Summary: Organophosphate esters (OPEs) have been found to be developmental toxicants in animal studies, but limited evidence is available in humans. This study investigated the association between gestational exposure to OPEs and gestational age, preterm birth, and newborn anthropometric measures. The findings suggest that certain OPEs may be associated with these outcomes, with some associations being specific to certain time windows and infant sex.

Summary: This study aimed to assess the impact of early-life exposure to an OPE mixture on child behavior. It was found that higher urinary concentrations of OPE metabolites during pregnancy and postnatal period were associated with child behavioral problems at 3 and 8 years, including internalizing, externalizing, and overall negative behaviors. However, there was no consistent pattern in terms of the direction of the effects or a particularly sensitive time point.

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: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: Air pollution is associated with a range of health issues and gestational exposure to environmental pollutants may be linked to neurodevelopmental disorders. This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

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.

Summary: Heteroatom doping can reconfigure the electronic structure of heterogeneous catalysts, leading to the development of advanced oxidation water purification materials with superior performance and stability. In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.
