The natural abundances of the stable isotopes of lead are used to identify natural and industrial sources of lead in the coastal waters of British Columbia, Canada. The 206Pb/207Pb ratios, used to characterize the lead source, had values of1.24 for coastal oceanic water, ∼ 1.22 for fjord waters receiving lead from mine tailings, and1.163 for waters near urban centers. The lead concentration data are in agreement with presently accepted seawater values.
