Overview

Assessment evaluates toxic metal concentrations in sediments of Subarnakhali River, indicating significant ecological risks.

Key Points

  • Toxic metals like Ni and Cd exceeded safe limits, posing serious ecological risks.
  • Mean concentrations showed Ni levels at 41.01 mg/kg, indicating substantial industrial impact.
  • Multivariate analyses linked Pb and As levels to both natural and human activities.
  • Ecological risk evaluations highlighted the long-term threat of toxic metals to aquatic ecosystems.
