Pollution Index is an estimation of the overall pollution in the city. The biggest weight is given to air pollution, than to water pollution/accessibility, two main pollution factors. A small weight is given to other pollution types.

Pollution Exp Scale is using an exponential scale to show very high numbers for very polluted cities and very low numbers for unpolluted cities. Therefore to calculate formula it uses the exponential function to calculate the index.

Last in this list are 4 cities of the Republic of South Africa. For example, Accra, the capital of Ghana, is not in this top 12 polluted city.

These data say that it is necessary to develop green protection projects. Ecology affects health and longevity.
