Human health risk in relation to air quality in two municipalities in an industrialized area of Northern Italy

► We assessed the impact on mortality of atmospheric pollution in two small municipalities. ► The methodology developed by the World Health Organization was used for this purpose. ► We found an excess of total mortality of 8 out of 177 in a year and a reduction of life expectancy. ► Particulate matter of aerodynamic diameter ≤2.5 μm had the highest health impact.
