Rossini P., Matteucci G., Guerzoni S. Atmospheric fall-out of metals around the Murano glass-making district (Venice, Italy). In: Environmental Science and Pollution Research, vol. 17 pp. 40 - 48. SPRINGER, 2010.
Murano's glass-makers have held a monopoly on quality glass-making for centuries known all over the world. Artistic glass manufacture entails exposure to complex mixtures of pollutants, including metals. A few studies have reported high levels of trace elements in marine waters, sediments and mussels around Murano and shown that emissions from Murano glass-making workshops significantly influence air quality in the Venice area. Nevertheless, to date, there is very little information on atmospheric concentrations and virtually none on atmospheric deposition fluxes of trace elements around the island. This study presents data on the distribution of trace elements in the air and atmospheric depositions around Murano, based on a 2-year sampling period. Atmospheric concentrations of As, Cd, Cr, Ni, Pb, Se and Zn were 1-2 orders of magnitude greater on the island of Murano than in the nearest urban areas (Venice and Mestre), with values higher than those reported for European industrial sites. The atmospheric deposition fluxes of all elements were also higher in Murano than those detected by other studies in Venice and Mestre and in the Porto Marghera industrial zone, with As, Cd, Sb and Se 1-2 orders of magnitude higher. As shown by our study, atmospheric loadings of metals around Murano are significant. These observations confirm that emissions from Murano also significantly influence atmospheric deposition in the Venice area. Specifically, the mean daily Cd flux in the most affected area, which includes the whole of the historic city centre of Venice, is ~18 g m-2 day-1, i.e. more than 65 times higher than the Dutch limit and more than three times higher than that of Germany.
