Overview

Randomized trial assesses trace metal bioaccumulation in marine fish, highlighting health risks for consumers.

Key Points

  • This study aims to investigate trace metal bioaccumulation in commercially important marine fishes and assess associated human health risks.
  • Conducted a multi-tissue assessment of eleven trace elements in five fish species from South Andaman Islands.
  • Analyzed concentrations in gills, liver, intestine, and muscle, using statistical multivariate analyses.
  • Performed a human health risk assessment focusing on muscle tissue consumption.
  • Eight trace metals were consistently detected, with liver being the primary reservoir for Cu, Fe, and Cd.
  • Human health assessment showed non-carcinogenic risk values within acceptable limits (HI < 1) for all species.
  • Total carcinogenic risk values for Cd and Pb exceeded USEPA benchmarks, indicating potential long-term risks for frequent consumers.
