Abstrakt: The findings in this article provide good evidence that the implementation of Pollution abatement strategies in Europr is having a direct effect on the level of PM2.5 and its various components. It is also hypothesised that the current economic climate, in reccesion since mid 2008 in Spain and many counties in Europe, is also affecting atmospheric pollutants through a reduction in activities associated with a healthy economy. A reduction in PM2.5 concentrations has been observed in Spain and across Europe, in most cases, this reduction has been gradual and consistent over time, implying the success of cleaner anthropogenic activities. Additional to this progressive trend, in some cases and especially for RB stations in the IP and Ispra in nothern Italy, a marked decrease has been recorded since 2008, coinciding with the begidding of the economic crisis. Finally, large scale meteorology has been shown to be an important influental factor on ambient aerosol concentrations across the Iberian Peninsula, with the North Atlantic Oscillation controlling the frequency of Sahara dust instrusions across the Iberian Peninsula in winter. Specially at MSY, organic matter and secondary inorganic aerosol accounted for the majority of the reduction observed.
