Abstract

This article presents results from investigations of run-off from materials used on buildings and other constructions obtained by short 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 were observed for a wide range of different materials used on buildings and other constructions. Sources of metal emission to the environment includes copper (Cu) surfaces, galvanized steel, impregnated wood, lead (Pb) surfaces, asphalt surfaces, painted material stainless steel and concrete. Metal emission rates from surfaces 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 the applicability of these data for calculations of metal flows in an urban environment is discussed.
