Release of Metals from Buildings,Constructions and Products during Atmospheric Exposure in Stockholm

This article presents results from investigations of run-off frommaterials used on buildings and other constructions obtained byshort term exposures of smaller model surfaces and one year exposures of larger materials surfaces on buildings and other constructions. Elevated concentrations of metals in run-off wereobserved for a wide range of different materials used on buildings and other constructions. Sources of metal emission tothe environment includes copper (Cu) surfaces, galvanized steel,impregnated wood, lead (Pb) surfaces, asphalt surfaces, paintedmaterial stainless steel and concrete. Metal emission rates fromsurfaces of copper and galvanized steel were measured from surfaces on buildings during 12 months exposure. The magnitude of metal emission form other surfaces was also estimated and theapplicability of these data for calculations of metal flows inan urban environment is discussed.
