Health Risk Analysis of Mercury, Lead and Cadmium in Some Commercial Fish Species Collected from Markets in Monrovia, Liberia

Abstract

The levels and health risks of mercury (Hg), lead (Pb) and cadmium (Cd) Contribution/ OriginalityThis study contributes to the existing literature on heavy metal toxicity in commercial fish species and associated health risks to fish consuming populace. It is the first work of such nature covering a wide variety of fish species consumed in Monrovia, Liberia and thus provides a basis for future studies.

Inferring trophic groups of fish in the central-east Atlantic from eco-toxicological characterization

“…The high Al content found both in Pelagic predators and the Superpredator group seems to be a factor to be taken into account in pelagic species, which bioaccumulate this non-essential metal (Cimmaruta et al, 2008, Murta et al, 2008b, Lea et al, 2015Brochier et al, 2018). Ngumbu et al (2017) studied the metal content in S. colias from Liberia, and reported values of 0.426 mg/kg for Cu, 2.503 mg/kg for Fe and 5.021 mg/kg for Zn. Rubio et al (2018) studied the metal content of T. picturatus in the Canary Islands and reported values of 1.51 mg/kg for Cu, 7.53 mg/kg for Fe and 4.69 mg/kg for Zn.…”
