Laboratory experiments from 2018-2019 measured the effects of 12 specific pesticides on the growth rates of the marine microalgae Tisochrysis lutea. The Australian Ocean Data Network hosts this dataset, which applies standard ecotoxicology protocols to assess risks to Great Barrier Reef ecosystems. Toxicity data for diuron, metribuzin, tebuthiuron, bromacil, propazine, simazine, imazapic, haloxyfop-p-methyl, 2,4-D, MCPA, fluroxypyr, and propiconazole were generated over 72-hour exposures.
Use Cases
- Modeling concentration-response relationships for pesticides based on specific growth rate inhibition data.
- Comparing the relative toxicity of Photosystem II (PSII) herbicides, alternative herbicides, and the fungicide propiconazole on a key marine microalga.
- Informing water quality guidelines and risk assessments for agricultural runoff entering the Great Barrier Reef catchment.
- Benchmarking algal toxicity data against effects on other marine taxa mentioned in the project aim.
Strengths
- Focuses on 12 specific, analytically pure pesticides (purity >= 98%) detected in the Great Barrier Reef catchment.
- Experiments followed standardized ecotoxicology protocols with controlled environmental conditions (28°C, 33 psu, 12:12 light:dark cycle).
- Data was generated from laboratory bioassays conducted over a defined period (2018-2019).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data reflects laboratory conditions; extrapolation to field scenarios may require additional considerations.
