The purpose of this publication is to describe a practical case study of a spatial environmental risk assessment investigating air pollution exposure on human health in a complex industrial site, represented by the South Durban Industrial Basin. The study showcase a urban management tool for larger Metro, capable of differentiating the point sources and mapping the pollutant concentrations and distribution in the residential communities. It is expected that the approach is a state of the art tool in order to estimate human exposure to the different air pollutants.
