Laboratory experiments from 2018-2019 measured the effects of ten herbicides on the microalgae Rhodomonas salina. The dataset includes growth rate data from 72-hour exposures and photosynthetic efficiency measurements from 24-hour exposures. This work was conducted under the NESP TWQ 3.1.5 project by AIMS and JCU.
Use Cases
- Modeling dose-response relationships for herbicides based on growth inhibition data.
- Comparing the toxicity of Photosystem II (PSII) and alternative herbicide classes on microalgae.
- Assessing environmental risk to the Great Barrier Reef catchment area based on laboratory toxicity endpoints.
Strengths
- Experiments tested ten specific herbicides (e.g., diuron, metribuzin, hexazinone) with analytical-grade purity.
- Standardized protocols were used for both 72-hour growth bioassays and 24-hour photosynthetic efficiency measurements.
- Cultures were maintained under controlled conditions (26 ± 1°C, 12:12 light:dark cycle) to ensure consistency.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to data_gov_au, focusing on herbicides detected in the Great Barrier Reef catchment.
