Summary: The air particulate matter generated during welding operations poses a major health risk to welders as they can cause respiratory diseases. This study aimed to analyze the elemental composition of the air particulate matter at a welding site using energy dispersive X-ray fluorescence (EDXRF) and total reflection X-ray fluorescence (TXRF). The results showed that the major contributors to the particulate matter were aluminum, silicon, calcium, and iron. The composition of the particulate matter was influenced by the welding material and adjacent construction activities. The study demonstrated the fast and non-destructive analysis capability of EDXRF and TXRF for air particulate samples.

Summary: Particulate matter (PM) pollution is a significant environmental concern due to its negative impact on human health. This study evaluates the daily exposure and inhaled dose of PM chemical compounds by integrating the concentrations measured in the micro-environments (MEs) where children spend most of their time. Results indicate that homes and schools contribute the most to children's daily exposure and inhaled dose. The study also highlights the high contribution of indoor sources to the organic fraction of particles, particularly in schools where mineral elements from dust resuspension and chalk usage stand out. Additionally, outdoor activities result in higher inhalation rates, leading to a higher contribution of outdoor particles to the inhaled dose. Overall, this study emphasizes the importance of indoor air quality in relation to children's exposure and health.

Summary: Particulate matter in Imperial Valley is sourced from agriculture, border crossing traffic, Mexicali emissions, and the drying lakebed of the Salton Sea, with dust storms often leading to PM10 exceedances. Research found that coarse PM induces an inflammatory response while fine PM increases the expression of certain genes, attributed not only to particle size but also to chemical composition. Community groups have worked on projects to monitor local air quality, but more information on the composition and toxicity of ambient PM from the region is needed.

Summary: This study finds that hosting the Tokyo Summer Olympics did not lead to an increase in COVID-19 cases in Japan. The transmission dynamics were mainly driven by population density, similar to other large cities in Japan. The study provides evidence that hosting mega sporting events is safe during the pandemic if strict non-pharmaceutical and pharmaceutical infection control measures are maintained. The successful implementation of preventive measures during the Tokyo Summer Olympics will serve as an example for future international events.
