A biomonitor as a measure of an ecologically-significant fraction of metals in an industrialized harbour.

摘要: Biomonitors are commonly used to assess levels of bioavailable contaminants in the environment, however relationships between biomonitor tissue concentrations and ecological effects rarely assessed. The present study investigated metal contamination within a highly industrialised harbour on sessile invertebrates. native oyster Saccostrea glomerata was deployed as across twenty-six sites test for correlations their tissues recruitment hard-substrate Concentrations lead copper were negatively correlated with densities dominant barnacle, Amphibalanus variegatus, positively polychaete, Hydroides elegans, two encrusting bryozoans Celloporaria nodulosa Arachnopusia unicornis. Results suggest that localised events drive contaminant availability these pose significant risk fauna. Biomonitoring studies may be enhanced by running concurrent surveys.
