Abstract

Trends of SO^, NO^ and CO concentrations in the city of Rome from 1 993 to 1996 are analysed in order to highlight improvements on air quality and their relationships with fossil fuel usage. The SO^ reduction, registered by government monitoring stations in the last four years, is correlated to fuel consumption and sulphur content. Monthly averaged SO^ emissions are estimated from residential heating and traffic sources. A similar approach is applied to NO^ and CO also considering that meteorological variables, although presenting minor fluctuations over the observed four years, have a direct influence on the experimental data. In particular wind speed has been taken into account to compare
