Summary: Air quality, both indoor and outdoor, is crucial for public health. This study introduces a new methodology using low-cost sensors and source apportionment techniques to understand the importance of different air pollution sources on indoor air quality. The results demonstrate the highest concentrations of PM in the bedroom, the highest PM spikes in the kitchen during cooking times, and the highest PM1 concentrations in the office due to outdoor infiltration. Source apportionment analysis shows that up to 95% of PM1 comes from outdoor sources in all rooms.

Summary: Sub-Saharan Africa is experiencing rapid urbanization, with air pollution emerging as a major concern in growing cities, especially in Accra, Ghana. The study found that commercial, business, and industrial areas have the highest levels of PM2.5 pollution, with concentrations 2-4 times higher than WHO guidelines. Additionally, PM2.5 levels peak during the dry dusty Harmattan period, and have decreased by 50% compared to measurements in 2006-2007. Effective policies are needed to reduce pollution levels and protect public health in urban areas.

Summary: Recently, low-cost sensors have emerged to measure air quality, allowing for high-resolution monitoring of air in large urban areas. However, these sensors require careful calibration, which often involves expensive and time-consuming field data collection. In this paper, a machine-learning-based approach is proposed to generate calibration models for new Particulate Matter sensors, using available field data and models from existing sensors. Experimental results show that this approach can produce accurate calibration models for new sensors with as few as four days of field data, comparable to models adjusted with data from periods ten times longer.

Summary: Air pollution remains a significant public health concern, necessitating the monitoring of air quality. Mobile, low-cost air quality measurement devices show potential in providing more comprehensive data for a region or municipality compared to stationary measurement stations due to their improved spatial coverage. This study presents the air quality measurements obtained from field tests using a low-cost air quality sensor node (sensor-box) and compares them with measurements from the regional air quality monitoring network. The sensor-box can collect geo-tagged measurements of various pollutants, as well as other environmental factors such as light and sound. The field tests were conducted using sensor-boxes mounted on utility vehicles operated by municipalities in Central Switzerland. Validation was performed against a measurement station belonging to the air quality monitoring network in Central Switzerland. The study also evaluates and discusses various data filtering methods to remove outliers and unfeasible values before further analysis. The results demonstrate a consistent measurement pattern during the field tests and good agreement with the reference station during the side-by-side validation test.

Summary: Freight transport in China has become increasingly important in terms of CO2 and air pollutant emissions, but few studies have used consumption-based methods to assess its environmental impact. Using multi-regional input-output tables, this study employs structural path analysis to determine the link between interprovincial trade-related freight turnover and responsible sectors of final consumption. The findings reveal significant growth in interprovincial trade turnover and associated emissions, with final consumption in equipment, construction, service, and food driving the most freight turnover. Optimizing China's industrial geographical layout and trade structure is essential to reduce CO2 emissions associated with the freight transport system.

Summary: Investigating the response of net ecosystem productivity (NEP) to phenological variation for crop ecosystems is important for understanding the impact of climate change on agriculture. However, the controlling mechanisms for rotation cropland ecosystems have not been well understood. This study used a 16-year flux observation to explore the potential of carbon flux phenology (CFP) and abiotic factors in interpreting the interannual variability (IAV) of NEP. The results showed that NEP was significantly controlled by different factors in wheat and maize seasons, and the carbon budgets varied depending on the season.

Summary: A clean heating campaign in northern China replaced coal with electricity or natural gas among 13.9 million rural households, resulting in significant reductions in PM2.5 emissions and exposure, as well as a decrease in premature deaths attributable to residential emissions. However, the benefits and costs were unevenly distributed, with residents in mountainous areas experiencing less benefit but paying more due to higher costs. Targeted investment and subsidies in less developed areas, as well as promoting less expensive alternatives, could help achieve improved air quality, reduced health impacts, and reduced inequity in future clean heating interventions.

Summary: Despite expanding the list of regulated waste electrical and electronic equipment (WEEE), there are still significant amounts of valuable-resource components that can be recycled from the unregulated WEEE. A study estimated the quantities of these components in China from 2010 to 2030 and found that the total economic value is expected to decrease initially and then gradually increase. Household baking apparatuses and electric fans are predicted to contribute the most to the weight of unregulated WEEE, while electronics are the most significant source of economic value. These findings can help bridge the knowledge gap and inform future policies on WEEE recycling.

Summary: A series of Bi2MoO6 nanosheets decorated with Pt nanoparticles were prepared, and the catalyst with Bi2MoO6 support prepared at 180°C exhibited high and stable activity in catalytic oxidation of formaldehyde at room temperature. The excellent catalytic performance was attributed to its large specific area and pore volume, high level of surface active oxygen species, high content of metallic Pt nanoparticles, and abundant oxygen vacancies. The good synergy and interaction between Pt and Bi2MoO6 promoted electron transfer, and facilitated the adsorption and oxidation of formaldehyde. The study provides new insights on the construction of high-efficiency catalysts for indoor formaldehyde removal.

Summary: The Chinese government has launched pilot stove renovation projects to improve household air quality. However, little research has been done on the impact of these projects on people's perception and willingness to participate. Additionally, factors affecting willingness to pay for the project in rural China are not clear. An investigation was conducted, revealing that the stove renovation project not only reduces PM2.5 exposure and mortality risk for rural residents, but also improves risk perception and self-protective willingness, especially for females and low-income residents. Moreover, higher income and larger family size were associated with higher risk perception and self-protective willingness, while willingness to pay for the project was related to support, benefits, income, and family size.

Summary: The iron and steel industry is significant for socio-economic progress but also contributes to greenhouse gas emissions and air pollution. This study provides a comprehensive analysis of global emissions from the industry over the past 60 years and predicts future trends up to 2050. The findings highlight the different trends for various pollutants, such as a consistent decrease in PM2.5 emissions from 1970 to 2000 and recent declines in NOx and SO2 emissions due to stricter controls. Projections suggest that developing nations (excluding China) will contribute a larger share of global PM2.5 emissions by 2050.

Summary: The large-scale batch growth of single-crystal 2D semiconducting transition metal dichalcogenides (TMDs) is crucial for pushing the limits of semiconductor technology. This study demonstrates that the interaction between TMD grains and the exposed oxygen-aluminium atomic plane in sapphire plays a more dominant role than step-edge docking in controlling the single-crystal epitaxy of these materials. Reconstructing the surfaces of the sapphire substrate to a single type of atomic plane enables the epitaxial growth of TMDs without the aid of step edges.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.
