Air pollution in Africa is coming to the forefront and must not be ignored. For example, in South Africa the mercury levels are severe due to coal combustion and gold mining. Mercury is absorbed from the air into the soil and water. [19] The soil allows the crops to absorb the mercury, which humans ingest.
For example, each year, more than 6 million people die prematurely from indoor and outdoor air pollution. Short-lived climate pollutants are largely to blame. Fast actions on short-lived climate pollutants, such as the widespread adoption of advanced cook stoves and clean fuels, have the potential to prevent over 2 million of premature deaths ...
Soot, particularly diesel exhaust pollution, accounts for over one-quarter of the total hazardous pollution in the air. [ 12 ] [ 22 ] Among these diesel emission components, particulate matter has been a serious concern for human health due to its direct and broad impact on the respiratory organs.
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.
Despite improvements in China, air pollution across the globe continues to pose the greatest external risk to human health, with countries in Asia and Africa suffering most of the impact, new ...
Black carbon is in the air and circulates the globe. Black carbon travels along wind currents from Asian cities and accumulates over the Tibetan Plateau and Himalayan foothills. Black carbon (BC) is the light-absorbing refractory form of elemental carbon remaining after pyrolysis (e.g., charcoal) or produced by incomplete combustion (e.g., soot).
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]
Air pollution can cause diseases, allergies, and even death; it can also cause harm to animals and crops and damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). [3] Air pollution can occur naturally or be caused by human activities. [4]
