Heavy Metal Exposure Risk from Consumed Fish in Bangladesh

This study compares heavy metal exposure risk from consumption of common fish species in Bangladesh, including both cultured and captured fish. The study analyzes metal content in fish samples and calculates daily intake, metal pollution index, hazard index, health risk index, and risk-based consumption limits.

  1. A comparative study of heavy metal exposure risk from the consumption of some common species of cultured and captured fishes of Bangladesh Mohammad Ruzlan Habiba, M. M. Hoquea, J. Kabirb, S. Akhterb, N. Sultanab and Y. N. Jollyb aDepartment of Food Engineering and Tea Technology, Shahjalal University of Science & Technology, Sylhet – 3114, Bangladesh bChemistry Division, Atomic Energy Centre, Dhaka-1000, Bangladesh

  3. Summary Indices • Daily Intake of Metal DIM (µg kg-1 body weight) = (Cmetal× Dfishintake× Kconversion factor /Baverage body weight) • Metal Pollution Index MPI (µg/g) = (Cf1 × Cf2 × ………. ×Cfn)1/n • Hazard Index HI= ∑HQ= HQFe+HQCu+HQZn+HQHg+HQPb • Health Risk Index HRI= DIM/RfD • Ingestion Intake IIngestion=CMF×IR×FI×EF×ED/BW×AT Non-Carcinogenic Risk/Toxicity Score TS = I/RfD Carcinogenic Risk/ Toxicity Score TS = I×SF • Development and Use of Risk-Based Consumption Limits CRlim= ARL× BW/CSF×Cm
