Dietary intake of trace elements from highly consumed cultured fish (Labeo rohita, Pangasius pangasius and Oreochromis mossambicus) and human health risk implications in Bangladesh

Concentrations of fourteen trace elements (essential and toxic) in the composite samples (collected from 30 different agro-ecological zones for the first time in Bangladesh) of three highly consumed cultured fish species (Labeo rohita, Pangasius pangasius and Oreochromis mossambicus) were measured by inductively coupled plasma mass spectrometry (ICP-MS). The estimated daily dietary intake (EDI) of all the studied elements was estimated on the basis of a calculation of the amount of fish consumed by Bangladeshi households (mean fish consumption of 49.5 g person(-1) d(-1)). The studied fish species pose no risk with respect to the EDI of Cd, Pb, Cr, Ni, Zn, Se, Cu, Mo, Mn, Sb, Ba, V, and Ag. Among the three studied fishes O. mossambicus showed higher content…
