Assessment of heavy metal(loid)s in selected small indigenous species of industrial area origin freshwater fish and potential human health risk implications in Bangladesh

Concentrations of nine heavy metal (loid)s (HMs) were determined in fourteen different small indigenous species (SIS) of freshwater fish using atomic absorption spectrophotometer (AAS) technique. Mean concentrations of HMs in the investigated SIS of fish samples ranged from (0.284–1.554), (0.002–0.035), (0.055–0.431), (0.005–0.018), (0.011–0.252), (0.216–23.948), (0.460–34.616), (0.529–3.281), and (4.473–50.560) mg/kg-fw for Pb, Cd, Cr, As, Hg, Mn, Fe, Cu, and Zn, respectively.
