Supplementary file 1_Heavy metal contaminants in eggs and hatchlings of olive ridley turtl

Nine heavy metals were analyzed in adult muscle, in-utero eggs, oviposited eggs, hatchlings, and sand from two olive ridley turtle rookeries in India. Arsenic was the most prominent metal in adult turtles, suggesting bioaccumulation, while Selenium was higher in egg components. The dataset, authored by Sharon Pradhan and last updated in April 2026, provides evidence of maternal and environmental heavy metal transfer to this endangered species.

Use Cases

• Modeling heavy metal bioaccumulation based on concentrations in adult turtle muscle tissue.
• Analyzing maternal transfer of contaminants based on comparisons between in-utero and oviposited eggs.
• Investigating environmental exposure pathways based on correlations between sand and hatchling metal levels.
• Assessing ecological risk for early life stages based on metal concentrations found in eggs and hatchlings.

Strengths

• Analyzes 9 specific heavy metals (Cr, Mn, Ni, Co, Cu, As, Se, Cd, Pb).
• Compares concentrations across 5 distinct sample types (adult muscle, in-utero eggs, oviposited eggs, hatchlings, sand).
• Data is collected from two specific rookeries (Devi and Rushikulya) in India.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX (1.1 MB), which may require format conversion for analysis.
