dc.description.abstract	Trace metals were analysed in 600 moss bag samples located in and around Helsinki. Accumulation of ash, Cd, Cr, Cu, Fe, Pb, Ni, V, and Zn over 5 months (Oct-Mar) was analysed with a AAS flame method. Largest amounts of metals were found near a refuse burning plant and near main streets with daily traffic of up to 50 000 vehicles. The relative contribution of different sources was estimated with a factor analytic method. The factors traffic, energy and incinerator factory showed significant loadings.
