Complex relationships between shallow muddy benthic assemblages, sediment chemistry and toxicity in estuaries in southern New South Wales, Australia

Non-metric MDS plot of relationships between benthic biotic samples and contamination categories showing replicate benthic samples. Large abundances of polychaetes in the families Spionidae, Capitellidae and Hesionidae and the bivalve mollusc families Galeommatidae and Semelidae contributed to significant differences in community composition in most contamination categories.227
