the impact of the banning of tributyltin-based antifouling paints on the sydney rock oyster, saccostrea commercialis.	two years after the banning in new south wales (australia) of tributyltin (tbt)-based antifouling paints for vessels under 25 metres in length, the impact on the sydney rock oyster, saccostrea commercialis, has been assessed. reduced growth and shell deformities present before banning were found to be absent and healthy oysters contained tbt at concentrations close to the detection limit of 0.2 micrograms sn kg-1. high tissue concentrations of both copper and zinc, prior to banning were also sig ...	1992	1523400
the detection of pollutant impact in marine environments: condition index, oxidative dna damage, and their associations with metal bioaccumulation in the sydney rock oyster saccostrea commercialis.	specimens of the sydney rock oyster saccostrea commercialis were deployed for a 3-month period at control and sewage disturbed marine locations in the hunter region, new south wales, australia. the dna damage product,8-hydroxyguanine, was measured by gc/ms-sim from chromatin extracts of the gill tissues of oysters to assess oxidative damage. the levels ranged from 11.5 to 18.8 modified bases per 10(7) guanine bases. although the condition indices were significantly different between the redhead ...	1996	8781068
direct toxicity assessment of volatile chlorinated hydrocarbon-contaminated groundwater and derivation of a site-specific guideline.	groundwater contaminated with a mixture of 14 volatile chlorinated hydrocarbons (vchs) discharges to an estuarine embayment in sydney, australia. a screening-level hazard assessment identified a potential risk to aquatic organisms from surface water contaminated by the groundwater. direct toxicity assessment of the groundwater was undertaken on 5 indigenous marine species to assess toxicity and derive a site-specific guideline. the testing included acute tests, subchronic tests on early life sta ...	2009	19125544
