Abstract

The increase of heavy metal concentrations in atmospheric aerosols, due to both natural and anthropogenic emissions, keeps high the interest around the resulting damages to health and to climate change. In this paper, we investigate the feasibility of using the atmospheric aerosol as a source of secondary raw materials, by estimating its contents in economically significant elements. We characterised the geochemical composition of the atmospheric aerosol of urban (Firenze), sub-urban (Arezzo), and rural (Piancastagnaio, Siena) areas in Tuscany, analysing common major, minor, and trace constituents of silicate rocks using inductively-coupled plasma atomic emission and mass spectrometry (ICP-AES and ICP-MS). We also determined the radiogenic isotope composition of the aerosols (Sr, Nd, and Pb) through thermal ionization mass spectrometry (TIMS). Although the results indicate that elemental quantities are not at exploitable grade, we think that this challenge has more advantages than simply the recovery of inorganic pollutants dispersed into the atmosphere: with appropriate technologies, the designed industrial plant could also serve to drastically reduce the content of Volatile Organic Compounds occurring in atmosphere, especially in urban areas. Considering this perspective, benefits undoubtedly overwhelm the high-costs of the business, providing the most precious commodity for life: clean air for the next generations to be living in our Planet.
