Trends of Ambient Air Pollution: S1
- Bertrand TCHANCHE (Alioune Diop University)
Background and study objective: To quantify PM2.5 and PM10 exposure differences between market infrastructure types and characterize temporal patterns.
Methods: Two low-cost PurpleAir sensors were installed to continuously monitor PM2.5 and PM10 concentrations for 8-week weeks (May 25–July 9, 2025), during dry season, in the exposed and control markets. Measurements were recorded every 2...
INTRODUCTION: Ambient air pollution, particularly fine particulate matter (PM₂.₅; aerodynamic diameter ≤2.5 μm), poses a growing public health concern, contributing to cardiovascular, respiratory, and metabolic diseases. In Africa, where over 1.1 million deaths were attributed to air pollution in 2019, monitoring efforts remain limited due to the lack of ground-based data and electronic health...
A significant component of urban particulate matter (PM2.5) is black carbon (BC). BC is a primary pollutant and is emitted during the combustion of carbonaceous fuels. It is one of the most powerful light-absorbing substances in the atmosphere and significantly contributes to climate change. Black carbon particles can penetrate deep into the respiratory tract and contribute to respiratory and...
Long-term monitoring of air pollutants is essential to evaluate the effectiveness of emission-reduction measures and to support compliance with the European Union (EU) Ambient Air Quality Directive (AAQD). In the Lazio region, including the metropolitan area of Rome, multiple studies provide complementary insights into trends of atmospheric pollution using satellite and ground-based remote...
