Toxicity of IFO 180 Fuel and Slickgone NS Dispersant to Antarctic Sea Urchin Larvae

Bioassay results showing the response of larval Antarctic Sterechinus neumayeri sea urchins to contamination from IFO 180 fuel and Slickgone NS dispersant. The metadata record contains two spreadsheets detailing survival data and hydrocarbon analysis results from experiments conducted at 0°C. Data was produced by the Australian Antarctic Data Centre (AU_AADC) and last updated in February 2014.

Use Cases

• Modeling dose-response relationships for fuel and dispersant toxicity based on concentration levels (100%, 50%, 20%, 10%, 5%, 1%, 0.1%).
• Comparing effects of single versus repeated pollution events based on test designs with and without water changes.
• Analyzing developmental stage impacts (blastula, gastrula, pluteus) on embryo abnormality and survival rates.
• Correlating biological survival outcomes with measured total petroleum hydrocarbon concentrations over time.

Strengths

• Experiments include controlled treatments for fuel only, chemically dispersed fuel, and dispersant only.
• Two distinct test designs simulate both single-event and repeated-pulse pollution scenarios.
• Hydrocarbon content was measured and integrated over the test periods to confirm exposure levels.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2014-02-28 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
