Multi-Year Monitoring of the Toxicological Risk of Heavy Metals Related to Fish Consumption by the Population of the Kendari Region (Southeast Sulawesi, Indonesia)

This study measured the concentrations of Hg, As, Ni, Cd, and Pb in six fish species commonly consumed Kendari. Samples were bought within local markets from 2012 to 2017 at end dry season. Results showed that mercury fluctuated between years species, except Caranx sexfasciatus, which no significant differences (Kruskall–Wallis, p-value > 0.05, df = 5) an average concentration 0.371 ± 0.162 µg g−1 DW.
