Hydrocarbon Exposure Concentrations for Antarctic Invertebrate Toxicity Tests

Integrated Total Hydrocarbon Content (THC) exposure concentrations in micrograms per liter, derived from water accommodated fractions of three marine fuels. Data was used to model sensitivity estimates for Antarctic invertebrates over exposure periods from 24 hours to 21 days. The dataset was produced by the Australian Antarctic Data Centre (AU_AADC) and last updated in June 2012.

Use Cases

• Modeling invertebrate sensitivity estimates using time-weighted mean THC exposure concentrations.
• Analyzing hydrocarbon loss over time in WAFs for fuels like SAB, MGO, and IFO 180.
• Comparing integrated THC exposure concentrations across different test durations from 24 h to 21 d.

Strengths

• Exposure concentrations are calculated using a time-weighted mean method integrating hydrocarbon loss.
• Covers three distinct fuel types: Special Antarctic Blend diesel, Marine Gas Oil diesel, and IFO 180.

Limitations

• Dataset size, row count, and specific column details are unknown.
• Data is temporally stale, with the last update occurring in 2012.
