Laboratory data from a study examining how microplastic shape affects egestion by the freshwater mussel Megalonaias nervosa and the subsequent bioavailability to the snail Planorbella pilbsryi. The dataset includes results from exposures using 61 µm red polyester microfibres, 79 µm blue polyester microfibres, and 6 µm red polystyrene microspheres, measuring ingestion, survival, and reproductive endpoints over 28 days. The data was contributed by author Ryan Prosser and last updated on May 23, 2026.
Use Cases
- Analyze the effect of microplastic shape on mussel egestion rates based on comparisons of microspheres and microfibres.
- Model trophic transfer of contaminants by comparing snail ingestion of pristine versus mussel waste-coated microplastics.
- Assess organism survival impacts based on exposure to specific microplastic types like blue polyester microfibres.
- Investigate reproductive endpoint effects in aquatic invertebrates exposed to microplastics.
Strengths
- Data originates from a controlled laboratory study with specific microplastic types (61 µm red polyester, 79 µm blue polyester, 6 µm polystyrene).
- Study design includes multiple biological endpoints: ingestion, survival, and reproductive output.
- Explicitly compares two particle shapes (microfibres vs. microspheres) and two exposure states (pristine vs. waste-coated).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update timestamp is in the future (2026-05-23).
