Summary: This study reviews the relationships between air pollution, metabolic profiles, and lung function from a life-course perspective. The findings suggest that a wide range of metabolites are associated with both short-term and long-term exposure to air pollution, and are also linked to lung function and respiratory diseases. However, the existing studies have limitations such as small sample sizes and heterogeneity in exposure assessment. The ongoing EXPANSE project aims to address these shortcomings by combining large European cohorts and harmonized data.

Summary: Pure fruit juice is similar to sugar-sweetened beverages in terms of sugar and fructose content, but it also contains beneficial components like polyphenols. Previous studies have shown that sugar-sweetened beverages are associated with higher asthma risk, while whole fruit consumption is associated with lower prevalence of asthma. However, there is limited research on the associations of pure fruit juice with asthma. This study investigated the associations of pure fruit juice, sugar-sweetened beverages, and whole fruit consumption with asthma prevalence in children aged 11 to 20 years.

Summary: This multicountry, observational, case-control study aimed to compare treatment regimens, inhaler techniques, medication adherence, and other characteristics of controlled and uncontrolled pediatric asthma. The study found that children in higher treatment steps had a higher risk of uncontrolled asthma, and the risk was also associated with a larger change in lung function post and pre-salbutamol. However, adherence and inhaler techniques were not related to the risk of uncontrolled asthma. Other factors, such as environmental factors and biological profiles, may influence the risk of uncontrolled asthma in this population.

Summary: Residential relocation is used as a natural experiment in epidemiological studies to assess the health impact of environmental changes. Predictors of relocation differ between adult and birth cohorts, and movers tend to experience higher levels of air pollution. Higher socioeconomic position is associated with a higher probability of relocation towards healthier levels of the urban exposome. These findings provide valuable insights for reducing bias in epidemiological studies using relocation as a natural experiment.

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.
