Summary: Air pollution caused by PM10 exceeding recommended limits is found in Jeddah city, Saudi Arabia. Differences in traffic, residential intensity, industrial, and non-road mobile machinery activities contribute to the variations in elemental concentrations at three different locations. Further evaluation is needed to understand the local influences and the health risks associated with high Cd concentrations.

Summary: This study assessed the associations between source-apportioned PM2.5 exposure and blood pressure changes among a panel of 36 health college students in Shanghai, China. It found that nitrate, traffic-related source, and coal combustion were significantly associated with increased blood pressure, with traffic-related PM2.5 exposure showing significant correlations with systolic, diastolic, and mean arterial pressure increases. The study suggests the importance of developing health-oriented PM2.5 source control strategies, especially focusing on traffic-related emissions.

Summary: This study investigated the associations of PM2.5 and PM2.5-10 with pulmonary function in asthmatic patients in China from 2017 to 2020. The results showed generally inverse associations of PM2.5 and PM2.5-10 with pulmonary function indicators, with PM2.5-10 having stronger associations, especially in southern China. The associations were significant and could last for one week, indicating potential hazards of PM2.5-10 on pulmonary function.

Summary: This study highlights the impact of socio-economic status on the distribution of dengue fever, with SES and gender ratio identified as key factors influencing dengue incidence. It found that cases are more likely to occur in poorer neighborhoods, and the effect of SES is partly mediated by population density and the presence of migrant groups.

Summary: This study investigates the levels of PAHs in settled dust in Greater Cairo houses (GCH), Egypt, and their impact on human health risk. The results show that vehicular emissions are the main source of PAHs, and houses on main streets have higher PAH levels. The carcinogenicity of PAHs in settled dust exceeds their mutagenicity. This study is important for understanding the risks and impacts of PAHs in GCH and rural houses (RH).

Summary: During the lockdown period imposed by the government of Saudi Arabia to control the spread of COVID-19, there was a significant reduction in air pollutant concentrations in Jeddah, particularly in nitrogen dioxide (NO2), carbon monoxide (CO), PM2.5, and PM10. However, ozone (O-3) concentration increased significantly. These changes are likely attributed to reduced economic and industrial activities during the lockdown.

Summary: Control of airborne particulate matter is crucial due to its negative impact on human health. Both exhaust and non-exhaust emissions from road traffic contribute to the concentration of both coarse and fine particles. Non-exhaust emissions, particularly from tyre dust, are now recognized as a significant source of particle emissions, surpassing exhaust emissions in many countries. However, analyzing tyre dust in the atmosphere poses challenges, as existing methods rely on chemical tracers that are not fully specific or quantitative. This article reviews these methods and highlights their strengths and weaknesses.
