Abstract:
Metadata record for data from AAS (ASAC) Project 2933.
While it is generally thought that Antarctic organisms are highly sensitive to pollution, there is little data to support or disprove this. Such data is essential if realistic environmental guidelines, which take into account unique physical, biological and chemical characteristics of the Antarctic environment, are to be developed. Factors
... that modify bioavailability, and the effects of common contaminants on a range of Antarctic organisms from micro-algae to macro-invertebrates will be examined. Risk assessment techniques developed will provide the scientific basis for prioritising contaminated site remediation activities in marine environments, and will contribute to the development of guidelines specific to Antarctica.

Test animals were collected from near shore environments at Casey Station, East Antarctica during Dec 2006 - Jan 2007, and transported to culturing facilities at the Australian Antarctic Division in Tasmania, where tests were conducted during 2007. The test animals were exposed to metals in non-renewable static tests in vials containing 50 mL of the test solution at ambient Antarctic coastal salinity of 34 ppt. Tests were held in temperature controlled cabinets (incubators) at a temperature of 0 degrees C (+/- approximately 1 degrees C). Eight to ten test animals were introduced into each of 4 to 5 replicate vials per treatment at test commencement, and were exposed for 10 to 12 weeks during which periodic observations were made.
Periodic oberservations (time since start of test) are given in hr (hours), d (days) or w (weeks). At each observation time, test animals were scored in one of the Endpoint categories described on each worksheet.
Each worksheet provides data for a particular test taxa (juvenile gastropods - taxonomy to be verified) for a given test number (T01, T07) and a given metal contaminant (copper, zinc, cadmium).
Test information is provided in the first 12 to 14 rows of each worksheet, e.g. Site of collection, Test start date, Endpoint categories etc.
Concentration micro grams per litre are nominal concentrations. Measured concentrations are provided in the worksheet: /Amph and Isop T01-02 CHEMISTRY SUMM
Test temperature was 0 degrees C unless otherwise stated. Unit for all temperature data are degrees C.
