“…Trace metal contamination information in fish from Ceará state is relatively limited, but Hg, due to its high toxicity and ubiquity in fish and shellfish, has been the most studied contaminant. Concentrations vary mostly with biology (size) and ecology (trophic position) of fish species (Lacerda et al, 2017;Moura and de Lacerda, 2018;Morgado et al, 2021), whereas in shellfish Hg concentrations present significant geographical variability, responding to the intensity of Hg anthropogenic emissions along the coast (Vaisman et al, 2005;Morgado et…”
