AU_AADC provides observed and predicted toxicity data from bioassays with two Antarctic marine microalgae species, Phaeocystis antarctica and Cryothecomonas armigera. The dataset includes results from exposures to mixtures of five metals at two ratios, with toxicity predicted using Independent Action and Concentration Addition models. The metadata record was last updated on April 30, 2018.
Use Cases
- Modeling mixture toxicity using Independent Action and Concentration Addition reference models based on the described methodology.
- Assessing the interactive effects of five-metal mixtures on microalgal growth rates based on the described bioassay data.
- Testing for significant departures from model additivity using the included R code with a deviation parameter.
- Comparing toxicity responses between two Antarctic microalgal species, Phaeocystis antarctica and Cryothecomonas armigera.
Strengths
- Includes data for two distinct Antarctic microalgal species, enabling comparative analysis.
- Provides R code for toxicity prediction and statistical testing, enhancing reproducibility.
- References specific published papers for single-metal toxicity data and experimental protocols.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2018-04-30; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
