Historical lead isotope record of a sediment core from the Derwent River (Tasmania, Australia): A multiple source environment

►Chemical and physical properties of a Derwent River sediment core were measured. ►Metal concentrations were Zn: 42-4500, Pb: 5-1090, Cu: 13-141, and Cd: 1-31 mg kg− 1. ►Enrichment factors were Pb: 0.9-144, Zn: 0.8-93, Cd: 0.8-30, Cu: 0.8-8.9. ►Pb isotope ratios reflected ores processed by the local zinc refinery.
