Abstract
This paper debate the risk assessment from a municipal waste incinerator for population health and environmental. In the base of input date about "classical" pollutants emissions (SO2, NOx, CO, particles and their secondary aerosols such as sulfates) and toxic metals (As, Cd, Cr, Hg, Ni and Pb) to the atmosphere it is determinate the risk and the damage costs using the software RiskPoll . These aspects can be quantified using a transparent methodology, easy to implement and who requires just few input data values.The emphasis is to obtain a reasonably accurate and relevant approximation of the impacts using a "simplified" approach. The following steps are fundamentals: select an impact assessment model; specify input data; calculate impact estimates; review results; perform sensitivity analyses.
