Juvenile Oyster Growth and Condition Under Long-Term Microplastic Exposure

An 80-day exposure study from the Government Digital Service measured the effects of three concentrations of 6-micron polystyrene microbeads on juvenile Pacific oysters (Crassostrea gigas). The dataset comprises separate files for shell growth and length, condition index, and lysosomal stability, compared against a control group. The data likely supports research into the sub-lethal impacts of microplastic pollution on marine bivalves.

Use Cases

• Modeling dose-response relationships for microplastic exposure based on the three concentration levels mentioned.
• Analyzing long-term effects on oyster shell growth and length over the 80-day study period.
• Assessing physiological health impacts through the condition index and lysosomal stability metrics.

Strengths

• Data originates from a controlled 80-day exposure study, providing longitudinal observations.
• Includes three distinct microplastic concentration levels (10^4, 10^5, 10^6 particles per liter) for comparative analysis.
• Measures multiple biological endpoints: shell growth, condition index, and lysosomal stability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Last update date is unknown; freshness unverified.
