Abstract
The lead levels in the river sediments of two small rivers draining the city of Christchurch, New Zealand, reflect nearby inputs from a lead accumulator battery factory and street dust carried into the river. The high levels found in the river sediments are not reflected in the levels in the sediments of the rivers' estuary. The lead species: PbCO3, PbSO4, PbS and Pb metal were found to exist in a sediment profile, the carbonate dominating near the top and sulphide near the bottom of the profile. Only a small fraction of the lead is held by sorption on to the sediments.
