Coal plant: risk, disease and prevention with on environmental impact.

Urban pollution is a current problem, constituting a serious health risk. Many pollutants are present in the urban atmosphere, they are mainly anthropogenic, resulting from the combustion of coal. Several studies have shown the harmful effects of these pollutants, particularly on the respiratory system. Through a library review, we want to explore the effects on the health of general population and of outdoor workers exposed to the products resulting from the combustion of coal, in order to compare them with the estimated effects of the pollutants from the new generation coal plants, certainly less harmful to the environment. In recent years investments in "clean technologies" have resulted in a rapid and significant reduction of all polluting emissions: sulfur dioxide, dust, oxides of nitrogen, ash and gypsum resulting from the desulfurization process. To conclude in the light of the scientific literature we can say that the activation of coal plants based on technologies for the maximum containment and optimal treatment of the production cycle is essential to defend both the environment and the health of the population. Nevertheless it remains necessary to ensure a systematic monitoring of the environment of sanitation and food processing of the population living in the area, with a long-term follow-up.
