Toxicological Data on Microplastics and Cadmium Exposure in Freshwater Crabs

Experimental data on the individual and combined toxic effects of polystyrene (PS) and polyethylene terephthalate (PET) microplastics and cadmium on female freshwater crabs (Sartoriana spinigera). The dataset includes measurements of behavior, growth, survival, haematobiochemical parameters, bioaccumulation, and histomorphology from a 14-day exposure study with five treatment groups and a control. It was authored by Ananya Chakraborty and last updated on 2026-05-27.

Use Cases

• Analyzing survival rates and behavioral alterations in crabs based on exposure to different toxicants.
• Comparing bioaccumulation levels of microplastics in gills and hepatopancreas across treatment groups.
• Investigating correlations between toxicant exposure and liver health markers like alanine aminotransferase and aspartate aminotransferase.
• Studying physiological stress through markers such as total cholesterol, triglycerides, glucose, and total protein.
• Assessing histomorphological damage to hepatopancreas and gills to understand organ function impairment.

Strengths

• Includes specific survival rate data, such as 33.33% ± 6.67% in the PS group.
• Reports quantitative bioaccumulation measurements, e.g., 44.67 ± 4.49 items/g of PS in gills.
• Contains measured values for physiological stress markers like alanine aminotransferase (9.33 ± 0.37 U/L in Cd group).
• Data is from a controlled experimental design with defined treatment groups and a 14-day exposure period.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (39.6 KB), indicating a limited experimental scope.
