Airborne particulate pollutants in the South Wales region

This project is collecting and undertaking detailed physiochemical analysis of PM10 from four sites in the South Wales region. Information is being provided on the heterogeneity of PM10 at the four sites, and the mass of the particles collected is being linked to their size distribution. Chemical analyses will assist with source apportionment, such as traffic, industry, mining and agriculture. Characterised samples of PM10 will be used in toxicological studies to determine whether the particles cause lung inflammation, increase lung permeability or initiate epithelial damage. A comparison of the results of these studies with previous findings from other environmentally and occupationally derived fine particles, with established safety levels, will permit the end-users to assess risks and supply public advice
