Source Apportionment of Fine Organic Particulate Matter (PM) in Central Addis Ababa, Ethiopia.

The development of infrastructure, a rapidly increasing population, and urbanization has resulted in increasing air pollution levels in the African city of Addis Ababa. Prior investigations into air pollution have not yet sufficiently addressed the sources of atmospheric particulate matter. This study aims to identify the major sources of fine particulate matter (PM) and its seasonal contribution in Addis Ababa, Ethiopia.

Chemical Characterization and Seasonality of Ambient Particles (PM) in the City Centre of Addis Ababa.

Ambient air pollution is a growing public health concern in major African cities, including Addis Ababa (Ethiopia), where little information is available on fine particulate matter (PM, with aerodynamic diameter <2.5 µm) pollution. This paper aims to characterize annual PM, including bulk composition and seasonal patterns, in Addis Ababa.

Source Apportionment of Coarse Particulate Matter (PM) in Yangon, Myanmar.

The Republic of the Union of Myanmar is one of many developing countries facing concerns about particulate matter (PM). Previously, a preliminary study of PM in 2018 suggested that the main source of PM in Yangon, the former capital, was vehicle emissions. However, this suggestion was not supported by any chemical composition data.
