Preliminary review of mine air pollution in Zambia

This review has revealed that there is a paucity of studies on mining-related air pollution in Zambia. The main identified air pollutants were SO 2 and particulate matter (PM), both fine and ultrafine (PM 10, PM 5.0, PM 2.5 and PM 0.1). The main sources of these pollutants were flue gases from smelter operations and dusts within the mines and
