Study: air pollution caused 1.1M deaths across Africa in 2019, toll from outdoor pollution rising

Green Car Congress

Air pollution was responsible for 1.1 Air pollution was responsible for 1.1 Deaths attributable to household air pollution and ambient particulate matter (PM 2.5 ) air pollution in Ethiopia, Ghana, Rwanda, and overall in Africa, 1990–2019. The most disturbing finding was the increase in deaths from ambient air pollution.
