    Abstract

    Sediments samples from six seaports of NSW, Australia were analysed for the presence of metal contamination. Geoaccumulation index (Igeo), enrichment factor (EF), pollution load index (PLI), potential ecological risk (PER) and sediment pollution index (SPI) along with multivariate statistical analysis were used to identify the pollution pattern and possible sources of metals in the ports. The results demonstrate Cu, Pb and Zn pollution (Igeo > 5) at most sites and enrichment of As, Ni, Mn (EF > 3) and other metals. The PER recommends serious pollution at Port Kembla and Eden. By contrast, PLI and SPI demonstrate high contamination in all ports with exception of Port Botany and Yamba. PCA and cluster analysis detected major groups of elements in which three distinct clusters of pollutants and sites were apparent by dendrogram which portray simple and effective baseline scenarios for port activity-related quality assessment of surface sediments.
