Metal analyses were carried out on precipitation samples collected from a sixteen station precipitation network along the Canadian shore of the Great Lakes from 1988-1994. The precipitation network was restructured to nine stations in 1994 and include the Canadian IADN Master stations, Point Petre in Lake Ontario and Burnt Island in Lake Huron. Sixteen metals (Al, Ba, Be, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, V, and Zn) were analysed using ICP (Inductively Coupled Argon Plasma Emission Spectroscopy). Results from 1988-1992 for the sixteen stations showed that metal concentrations in order of abundance were Fe, Al, Cu, Zn and Pb. Concentrations of other metals were generally less than 1 {mu}g/L. Metal concentrations in precipitation were fairly uniform throughout the Great Lakes basin. Recent metal data from the two Canadian IADN stations at Burnt Island and Point Petre were comparable with the US data with the exception of copper which was about one order of magnitude higher at the Canadian stations.
