Implication

Evaluation reveals high heavy metal levels and health risks in finfish from Tamil Nadu, indicating urgent need for remediation.

Key Points

  • The aim is to assess heavy metal concentrations and potential health risks to humans from finfish in Tamil Nadu's coastal regions.
  • Used atomic absorption spectrophotometry to quantify metal levels in finfish and sediments.
  • Conducted hazard index analysis to evaluate health risks associated with metal exposure.
  • Utilized hierarchical cluster analysis to identify major contaminants linked to human activity.
  • Found the order of metal concentrations as Fe > Zn > Pb > Cu across all sites.
  • Bioaccumulation factor for Zn exceeded safety limits, indicating high uptake by fish.
  • Hazard index exceeded safe levels (HI > 1) at all sites, particularly high at Mallipattinam (HI = 3.48).
