title: Influence of industry on the geochemical urban environment of Mieres (Spain) and associated health risk.
abstract: This study is concerned with the elemental composition of soils and street dust collected in an historical industrial city of approximately 27,000 inhabitants, where old Hg mining and metallurgical activities strongly affected the load of heavy metals in the urban environment. For the purpose of the study, representative samples of soils and street dust were collected at different locations in the whole urban area (3 km2). Elevated mean concentrations of As in soils and street dust (69 and 135 micrograms g-1, respectively), and Hg (3.07 and 4.24 micrograms g-1, respectively), compared to background levels and to those found in other cities, reflect the anomalous geochemical nature of these materials and the strong influence exerted by the old mining sites.
