Food toxicity and health risks due to heavy metals exposure through fish consumption have become a major concern for this present era. Since, both cultured and captured fishes are largely consumed in Bangladesh, a comparison of heavy metals between those fishes are must. Seven sample species were collected from a tributary of the Meghna River at Lakhai Kheyaghat, Habiganj, Bangladesh and fish market of Dhaka, Bangladesh. Energy Dispersive X-Ray Fluorescence (EDXRF) Spectrometer were used to measure the metal concentrations. The sequence of metal concentration in the flesh of fishes was Fe > Zn > Cu > Pb > Hg for both fish categories with mean concentrations (mg kg-1) of 69.8 ± 7.5 > 56.42 ± 8.59 > 19.52 ± 2.63 > 0.44 ± 0.18 > 0.39 ± 0.04 respectively for cultured fishes (n = 21). Statistically, mean Cu, Zn, and Pb concentrations from captured fishes flesh samples were...
