Toxicity of Fuel and Dispersants to Antarctic Polychaetes, 2014

The dataset from the Australian Antarctic Division contains results from bioassays conducted between 19 July and 2 September 2014. It shows the response of Antarctic Polychaetes Ophryotrocha orensanzi to contamination from IFO 180 fuel and the dispersants Ardrox 6129, Slickgone LTSW, and Slickgone NS. Test solutions were prepared following specific methods and tested at controlled concentrations and temperatures.

Use Cases

• Modeling dose-response relationships for fuel and dispersant toxicity based on described concentration levels (e.g., 100%, 50%, 20%, 10% for WAF).
• Comparing the relative toxicity of different chemical dispersants (Ardrox 6129, Slickgone LTSW, Slickgone NS) based on the bioassay results.
• Assessing the combined effects of fuel and dispersants (CEWAF) on a specific Antarctic species, Ophryotrocha orensanzi.
• Calibrating environmental risk models for Antarctic regions using experimentally derived toxicity data.

Strengths

• Experimental conditions are precisely documented, including temperature control (0 ±1°C) and specific preparation methods (e.g., 1:25 fuel to FSW ratio for WAF).
• Test concentrations are explicitly defined for Water Accommodated Fractions (WAF) and Chemically Enhanced WAF (CEWAF), facilitating reproducibility.
• The dataset is focused on a specific, ecologically relevant Antarctic species, Ophryotrocha orensanzi.

Limitations

• Last updated 2014-09 02 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
