Description
The 210Pb-dating technique has shown particular promise for the study of recent environmental change by enabling the establishment of chronologies for contemporary environmental processes. In this paper two case studies are discussed. Case Study (1) looks at trace element and heavy metal levels in the estuaries of the Georges River and the Hacking River which are partly located in suburban Sydney and Case Study (2) looks at blooms of the toxic dinoflagellate Gymnodinium catenatum which were first observed in Tasmanian waters, principally the Huon and Derwent Rivers in 1980. In both cases the 210Pb dating technique has been used to establish the sequence of sediment deposition in order to associate an age to the sediment layer which contains the entity under investigation
