Description :
5.A multidisciplinary study has been carried out on the dispersion modalities of asbestos minerals from ophiolites outcrops in the area of the Pollino National Park (Calabria-Lucania border, southern Italy) by integrating geological and geomorphological mapping, quantitative geomorphic analysis, petrological and mineralogical analyses of outcropping crystalline-metamorphic rocks, aerosol analyses, and remote sensing investigations. This study allowed to assess the degree of environmental hazard due to release of asbestos fibres. The comparison of natural and human factors in controlling asbestos release in areas characterized by different morphological conditions revealed that erosional (mainly fluvial) processes promoted an intense spreading of asbestos minerals, even in an area wider than the original ophiolite (mainly serpentinite) outcrops. - (NF)
