Even so, air pollutants are causing a variety of health and environmental problems. These pollutants are a threat to the population of Africa and the environment they try so hard to sustain. [31] In 2019, air pollution killed 1.1 million people across Africa, according to a study published in The Lancet Planetary Health in October 2021. [32]
Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike. Air pollution is a particularly big problem in emerging and developing countries, where global environmental standards often cannot be met. The data in this list refers only to outdoor air quality and not indoor air quality, which ...
The January 2024 version of the WHO database contains results of ambient (outdoor) air pollution monitoring from almost 5,390 towns and cities in 63 countries. Air quality in the database is represented by the annual mean concentration of particulate matter (PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 micrometers, respectively). [1 ...
Outdoor particulate pollution is the largest cause of death (4.7 million), followed by indoor air pollution (3.1 million) and ozone (0.5 million). [ 5 ] The World Bank has estimated that welfare losses (premature deaths) and productivity losses (lost labour) caused by air pollution cost the world economy over $8 trillion per year.
Diseases caused by pollution, lead to the chronic illness and deaths of about 8.4 million people each year. However, pollution receives a fraction of the interest from the global community. [1] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
There are a range of environmental issues in Southern Africa, such as climate change, land, water, deforestation, land degradation, and pollution.The Southern Africa region itself, except for South Africa, [1] produces less carbon emissions but is a recipient of climate change impacts characterized by changes in precipitation, extreme weather events and hot temperatures.
However, coal use is responsible for the majority (60 to 80%) of black carbon emissions in Asia and Africa, while diesel combustion produces 70% of black carbon in Europe and The Americas. [42] Black carbon in the lower atmosphere is a major contributor to 7 million premature deaths caused by air pollution every year. [43]
Overall, air pollution causes the deaths of around ca. 7 million people worldwide each year, and is the world's largest single environmental health risk, according to the WHO (2012) and the IEA (2016).
