The study on location selection of municipal solid waste incineration power plant based on health risk assessment.

The atmospheric environmental effect and human health risk of some characteristic pollutants such as mercury, cadmium, lead and dioxin emitted from a certain pre-constructed municipal solid waste incinerator were simulated for finding a more optimized location for the incinerator from the optional location scenario A and B. The results showed that the ratio of maximum ground concentration to standard concentration for each pollutant was lower in scenario B than A. Therefore, it is better for scenario B than A in terms of environmental capacity. Although the human health risks were both acceptable for the two scenarios, there were no sensitive receptors around the high-risk areas for scenario B while there are receptors closer to high-risk areas for scenario A. Therefore, the scenario B was lower than A in respect of human risk. Considering the two kinds of location selection scenarios, the scenario B was recommend for the final selection and human health risk assessment could be used as an important basis for the construction of waste incineration, particularly in the aspect of the location selection of incinerator.
