Experimental data assesses lead release from lost fishing sinkers and jigs into water at cold and warm temperatures. The study compares effects to dissolved lead using the freshwater organism Daphnia magna, measuring metal release and impacts on growth and reproduction. The dataset was authored by Erin M. Leonard and harvested from the Borealis Dataverse.
Use Cases
- Modeling lead pollution risk in lakes and rivers based on measured release rates from fishing weights.
- Comparing the toxicity of lead from fishing gear to dissolved lead forms for ecological risk assessment.
- Assessing the long-term sub-lethal effects of lead exposure on aquatic invertebrate populations based on reduced growth and reproduction metrics.
- Evaluating the release of co-contaminants like zinc and cadmium from lost fishing gear mentioned in the description.
Strengths
- Data includes experimental results from testing multiple types of fishing weights, providing comparative insights.
- Tests were conducted under both cold and warm temperature conditions, reflecting seasonal variability.
- Findings include measurements of lead release levels and sub-lethal effects on a model organism over time.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
