Determination of concentrations of some elements in marine consumables from Thane creek area (Mumbai, India) using ED-XRF technique; and risk assessment

Abstract

ABSTRACT Six marine consumable species, namely, Bombay duck (Harpadon nehereus), Ghol (Protonibea diacanthus), Rawas (Eleutheronema tetradactylum), Prawns (Dendrobranchiata), Surmai (Scomberomorus guttatus), and Bangda fish (Rastrelliger kanagurta) were collected for assessment of minor and trace element contents. EDXRF methods (using secondary targets and filters) were optimised and validated for quantification of V, Cr, Mn, Fe, Ni, Cu, Zn Se, As, Br, Cd, Pb, Sr, K, Ca Na, Mg, and Al in these samples. The levels of each target element were found to be comparable to those reported across the globe. The potential health risk evaluated for selected trace and toxic elements showed no adverse impact on human health (Hazard Index < 1) from exposure to these elements through consumption of these marine species.
