Concentrations of Co, Cu, Ph and Zn were determined in 107 surficial. sediment samples from the continental margin adjacent to Sydney, Australia. The spatial distributions of trace metals in the sediments and the mud content are similar and increase with greater distance from the coast. In contrast, normalization of the concentrations of Cu, Ph and Zn in the total sediment with Co enables a coastal anthropogenic source to be identified. The spatial distribution of Co-normalized concentrations of Cu, Ph and Zn in total sediment is similar to the distribution of these trace metals in the fine fraction of sediment (<62.5 m), indicating that Co may be used as a normalizing element for determining contaminant sources in the marine environment near Sydney.
