Source Apportionment of Fine Organic Particulate Matter (PM_2.5) in Central Addis Ababa, Ethiopia.

ABSTRACT: 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_2.5) and its seasonal contribution in Addis Ababa, Ethiopia. Twenty-four-hour average PM_2.5 mass samples were collected every 6th day, from November 2015 through November 2016. Chemical species were measured in samples and source apportionment was conducted using a chemical mass balance (CMB) receptor model that uses particle-phase organic tracer concentrations to estimate source contributions to PM_2.5
