Summary: The study highlights the importance of considering both indoor and outdoor exposure in assessing air pollution inequality. It reveals that low-income groups are exposed to lower ambient PM2.5, but higher indoor PM2.5 due to residential emissions. The transition to clean household energy sources has significantly improved indoor air quality and reduced overall PM2.5 exposure, benefiting low-income groups. The study also shows a decreasing trend in PM2.5 exposure inequality over time.

Summary: A multinational measurement campaign was conducted to develop household and personal PM2.5 exposure models, which can be used to quantify levels of household air pollution (HAP). The models found that primary cooking fuel type, heating fuel type, country, and season were highly predictive of PM2.5 concentrations.

Summary: The study found that in settings of household solid fuel use, individual variability in exposure to air pollution is mainly dominated by differences within participants. Outdoor PM2.5 is the main variable affecting within-participant exposure, while household fuel use and smoking status explain between-participant variability. This suggests that reductions in air pollution exposure require simultaneous efforts to reduce both outdoor and indoor sources.

Summary: This study investigated the association between oxidative potential (OP) and birth outcomes in relation to personal exposure to fine particulate matter (PM2.5). The results showed that personal OP exposure was associated with fetal growth restrictions, specifically decreased weight and height at birth, possibly to a larger extent than PM2.5 mass concentration alone.

Summary: Traditional cooking with solid fuels creates household air pollution, leading to millions of premature deaths worldwide. This study analyzed the impact of household and personal variables on exposure to fine particulate matter and black carbon. Stove type was found to have the greatest influence on exposure. Future research should include tracking participants' cooking behaviors and daily activities to further understand exposure variations.

Summary: Exposure to air pollution can have negative health impacts on children, and this exposure may vary by socio-economic status (SES). A model estimating personal exposure to PM2.5 for 1.3 million children in the Greater London region shows differences in exposure levels across socio-economic groups, with lower-income households generally having higher exposures. However, approximately 57% of London's school-aged population, across all income groups, still exceeded the guideline limits set by the World Health Organisation. These findings highlight the importance of addressing residential indoor sources of PM2.5 in order to reduce personal exposure for school children in London.

Summary: Cookstove emissions contribute to indoor air pollution in developing countries and rural communities. This study investigates the stability of particulate matter (PM) filter samples collected in remote research sites for evaluating cookstove emissions. The results suggest that measurements of PM2.5 and extractable organic matter (EOM) are consistent across different storage conditions and durations, particularly for samples with low EOM levels. This study provides insights for improving protocols and filter storage procedures in exposure and intervention research conducted in resource-limited countries.

Summary: The Kathmandu Valley in Nepal experiences poor air quality, particularly with high concentrations of PM2.5 during the dry winter season. The major sources of PM2.5 are garbage burning, biomass burning, and fossil fuel combustion, with organic carbon and elemental carbon as the main components. Secondary organic aerosols mainly originate from aromatic volatile organic compounds.

Summary: Severe air pollution in China and India poses a health threat to more than one-third of the global population. China adopts a centralized approach with enforced policies, while India's approach reflects power division and relies on legislative and judiciary systems. Studies show that China's efforts have improved air quality significantly, while India's policies have been largely ineffective. However, both approaches can be effective with strong political will and clear accountability systems. Key lessons for developing countries include taking advantage of post-crisis policy opportunities and targeting cost-effective improvements.

Summary: Microenvironmental concentrations and time-activity patterns have a significant impact on personal exposure to PM2.5. This study collected real-time personal PM2.5 measurements during routine activities in different microenvironments from 66 non-smoking retired adults in Nanjing and Beijing. The results showed substantial variations in PM2.5 concentrations between different microenvironments and activities. The highest concentrations were observed in restaurants, associated with sources such as passive smoking and cooking emissions. The indoor PM2.5 concentrations were moderately to highly correlated with outdoor concentrations, except in restaurants and during passive smoking.

Summary: Urban agriculture is being recognized as a valuable approach to address food security and public health issues in cities in the US. However, the potential risk of exposure to heavy metals and metalloids in contaminated soil is a concern. Community-engaged research has shown promise in studying such exposures and involving all stakeholders. This particular study examined lead concentrations in soil from urban agricultural and residential sites in Atlanta and rural sites in Georgia, and led to actions by government agencies to address contamination in certain areas.

Summary: Urban agriculture provides local, fresh food, but gardening in urban areas can lead to lead soil contamination. Through community partnerships, we conducted soil screening programs (soilSHOPs) in Atlanta to raise awareness about lead exposure. This initiative also led to the identification of a Superfund site by the US Environmental Protection Agency.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
