Question and answer
In 10-15 lines critically discuss 5 ways in which air pollution impacts on the communities withini South Africa
The two major types of pollution in South Africa are air and marine pollution. The industrial sector is the prime contributor to air pollution. [ More than 90% of South Africa's electricity is generated from the combustion of coal that contains approximately 1.2% sulphur and up to 45% ash. Coal combustion can lead to particulate matter in the air, as well as contribute to acid rain. While major cities in South Africa do not possess pollution levels comparable to many major cities in China, India or Mexico, pollutant levels are not insignificant. Nitrogen dioxide levels in Cape Town, South
Africa, for instance, were significantly higher than those measured in Calcutta, and surpassed the World Health Organization's annual mean guideline for air quality standard of 50 micrograms per cubic meter. In addition to industrial pollution, low-level atmospheric pollution often results from coal combustion in stoves, as well as coal-heated boilers that are found in hospitals and factories. Vehicular emissions, while not nearly as significant as in cities such as New York, Tokyo or Los Angeles, have a negative impact on the environment. Regulations apply to diesel-powered vehicles and are geared towards ensuring proper maintenance. Enforcement, however, is weak and sporadic. ]
