Summary: This study evaluated the concentrations of trace metals in indoor dust from homes in 35 countries and identified the main sources of these metals along with associated household characteristics. The findings suggest that factors such as home age, peeling paint, and garden access are important considerations for managing potential risks posed by indoor house dust, with chromium concentrations in indoor dust having the greatest health risk impact.

Summary: The study found that the concentrations of Cr, Ni, Zn, and Pb in South China Sea sediments are significantly positively correlated with fine-sized fractions and TOC, while the concentration of As is not positively correlated with other metals. The relatively positive correlations of Cd with various elements suggest it comes from different sources.

Summary: The city of Manaus, as the largest industrial city in the northern Brazilian region, is characterized by haphazard urbanization. The study aimed to investigate trace element pollution in urban soils and its potential risks to human health. Results showed that some soil samples were considerably or highly contaminated, with a higher carcinogenic risk for Cd and Pb exceeding safety limits. Overall, the noncarcinogenic health risk was considered low for both children and adults.

Summary: Trace metals in street dust in different zones of Nanchang city were assessed using the enrichment factor (EF), showing regional and seasonal variations. While Zn, Cd, and Pb exhibited similar variations, likely influenced by industrial and traffic emissions, Ni and As were found to have different sources, with Ni being influenced by land use type and As by natural sources. Industrial discharges and traffic emissions were identified as the main sources of trace metals, with significant regional differences in their contributions to pollution levels. Additionally, areas with high ecological risk index (ERI) corresponded to seriously polluted areas, indicating a complex relationship between EFs and environmental risk.

Summary: Trace metals in sediments from the Chester River were investigated to understand their distributions and potential sources. The concentrations of lead, arsenic, nickel, chromium, and copper exceeded sediment toxicity guidelines in a significant proportion of samples. Enrichment factors for cadmium, silver, lead, arsenic, and zinc were elevated above natural background levels. Nickel, copper, zinc, and cadmium showed significant differences in enrichment factors between different segments of the river. Cadmium and arsenic enrichments were most likely from the application of fertilizers in the watershed, while active marinas were identified as important sources of metal enrichment, especially for copper.

Summary: This study assesses the ecotoxicological effects of the failure of an iron mining dam in Brumadinho, Brazil. The results show that the metal concentrations in the tailing samples exceeded the limits set by Brazilian law, causing severe reproductive effects on aquatic and soil organisms. The study also found significant differences in toxicity between different areas, which might be attributed to variations in the energy and flow of the tailings.

Summary: Saudi Arabia faces challenges in providing enough clean water to its population as one of the largest and fastest-growing nations outside its own continent. This study collected 49 groundwater samples from June to December 2021 and used different analytical techniques to determine the concentrations of anions and cations. The results of the hydrogeochemical study show that groundwater is impacted by aquifer matrix disintegration, water infiltration from irrigation systems, and water-rock interactions. The collected groundwater samples contained acceptable concentrations of anions (HCO3-, CO32-, Cl-, NO32-, and F-) and cations (Na+, K+, Ca2+, and Mg2+), making them suitable for human and industrial consumption.

Summary: The study investigates the spectroscopic fingerprinting, pollution status, and health risk of PM-associated PTMs in Lahore, Pakistan. The results show distinct compositional and pollution characteristics of PTMs in urban PM across different functional areas. Different chemical species of Zn, Pb, and As were found in PM from various functional areas. The cumulative representation of PTMs pollution indicates that Cd is heavily polluted while Cr and Ni are moderately polluted PTMs. The industrial area has the highest pollution status for several PTMs including Cd, Cu, Cr, Ni, and Zn. PTMs pose a high non-cancerous risk in certain areas, mainly due to Zn, while Cr poses a cancerous risk beyond the tolerable range.

Summary: Unconventional oil and natural gas development (UOGD) in the United States has expanded rapidly in recent decades, raising concerns about its impact on air quality. This study conducted extensive air monitoring during the development of several large well pads in Broomfield, Colorado, providing a unique opportunity to examine changes in local air toxics and VOC concentrations during well drilling and completions and production. The study identified significant increases in VOC concentrations during drilling operations, highlighting the importance of emissions from synthetic drilling mud. The findings suggest opportunities to mitigate emissions during UOGD operations.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.

Summary: Accurate measurement of atmospheric reactive mercury is challenging due to its reactivity and low concentrations. The University of Nevada, Reno Reactive Mercury Active System (RMAS) has been shown to be more accurate than the industry standard, but has limitations including long time resolution and sampling biases. Increasing the sampling flow rate negatively affected RM concentrations, but did not impact the chemical composition of RM captured on membranes.

Summary: This study estimated the daily exposure concentrations of PM2.5 for elderly individuals residing in different regions of Taiwan using land use regression with machine learning (LUR_ML) and microenvironmental exposure (ME) models. The accuracy of the models varied across regions, with the ME models exhibiting higher predictions and lower biases. The use of region-specific microenvironmental measurements in the ME model showed potential for accurate prediction of personal PM2.5 exposure.

Summary: This study developed a sensitive method to measure the metallic components of atmospheric fine particulate matter (PM2.5) and compared the results with different analysis methods. The concentrations of metallic components in personal PM2.5 samples were found to be significantly different from corresponding fixed-site samples. Personal sampling can reduce exposure misclassifications, and measuring metallic components is useful for exploring health risks and identifying sources of PM2.5.

Summary: Increasing concentrations of microplastics in the Earth's atmosphere could have adverse effects on ecosystems and human health. The deposition rate of airborne microplastics is influenced by both land use and climate, and a global analysis suggests that climate may have a greater impact on the concentration and deposition rate of microplastics than land use.
