Summary: This study presents the largest scale research conducted in a single urban area, using monitoring of different particulate matter concentrations and developing regression and machine learning models to successfully predict 24 elemental components in eight Southern California communities. It was found that incorporating spatiotemporally resolved meteorology into the models improved the accuracy of predictions for particle distribution, especially near roadways for non-tailpipe emissions.

Summary: The popularity of facemasks has increased in northern China due to severe air pollution. While wearing facemasks can reduce exposure to particulate matter, the protection is limited as people spend most of their time indoors. Installing indoor air purifiers is a more effective strategy for long-term protection against particulate matter exposure.

Summary: Ambient fine particulate matter (PM2.5) pollution is a major problem in China. Reductions in particulate sulfate, driven by desulfurization efforts, have led to a decrease in PM2.5 levels. However, the toxicity of particulate sulfate and its long-term trend is difficult to estimate. Using spaceborne sensors and machine learning techniques, a sulfate prediction model was developed. The model performed well and demonstrated a significant decrease in sulfate levels and associated health benefits.

Summary: This study demonstrates the efficacy of roadside green infrastructure (GI) in improving local air quality by capturing and reducing airborne particulate matter (PM). A recently installed 'tredge' was found to be effective in intercepting and depositing PM, resulting in significant reduction in exposure in a school playground setting.

Summary: This study investigated the impact of short-term exposure to particulate matter (PM2.5) on work loss due to sickness. The findings showed a positive association between short-term ambient PM2.5 exposure and work loss, which was stronger among individuals with higher exposure to wildfire smoke. This suggests the need for further strengthening of PM2.5 standards in California to protect public health.

Summary: According to previous theoretical work, researchers have discovered that the binary oxide CuO can become a room-temperature multiferroic material by applying pressure. They confirmed this by neutron diffraction, showing that the multiferroic phase in CuO can reach 295 K with the application of 18.5 GPa pressure. They also developed a spin Hamiltonian based on density functional theory and employing superexchange theory, which was able to reproduce the experimental results. This study provides stimulus for developing room-temperature multiferroic materials using alternative methods, such as epitaxial strain, based on existing low temperature compounds, for tunable multifunctional devices and memory applications.

Summary: This qualitative study explored the barriers and enablers of a collaborative quality improvement (C-QIP) strategy for cardiovascular disease (CVD) care in India. Providers and health administrators identified barriers such as high patient volume, physician burnout, and lack of electronic health records, while patients faced barriers such as low health literacy and high treatment costs. However, standardized treatment protocols, improved physician-patient relationships, and enhanced patient self-care were identified as key enablers for C-QIP implementation.

Summary: The current air quality management primarily relies on data from monitoring stations in cities, neglecting non-urban areas. This paper summarizes the PM2.5 pollution in India between 1998 and 2020 using satellite data and a chemical transport model. The results show a steady increase in PM2.5 concentrations across the country. Fuel combustion is identified as the main source of PM2.5 pollution in India, requiring measures to reduce emissions to meet national and international standards.

Summary: The lockdown in India reduced air pollutant emissions and led to a decrease in PM2.5 and ozone concentrations, although the response of ozone concentration to reductions in precursors was not consistent across the region. The study highlights the importance of considering both NOx and VOC emission reductions and regional characteristics in air pollution management strategies to reduce exposure to both PM2.5 and ozone.

Summary: This study aimed to describe the cardiovascular risk factors, clinical manifestations, and outcomes of COVID-19 patients hospitalized in different income countries. The study found that older age, male sex, pre-existing coronary heart disease, renal disease, diabetes, ICU admission, oxygen therapy, and higher respiratory rates were predictors of increased mortality. Asians, Blacks, and Hispanics had a higher risk of death compared to Caucasians. Patients from low, lower-middle, and upper-middle-income countries had a higher risk of death.

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.

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.

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.
