The intake of arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb), polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), polybrominated diphenylethers (PBDEs), polychlorinated diphenylethers (PCDEs), hexachlorobenzene, and polycyclic aromatic hydrocarbons through fish and seafood consumption by children of Catalonia, Spain, was assessed. In 2005, samples of the 14 most consumed marine species in Catalonia were randomly acquired in various cities of the country. Analysis of the above chemical contaminants were determined according to the appropriate analytical techniques and the daily intakes were estimated. For most pollutants, intake was higher in boys than in girls. Average exposure of children to contaminants through fish and seafood consumption did not exceed the respective tolerable daily intake of those pollutants for which it has been already established (metals, PCDD/Fs plus dioxin-like PCBs, HCB, and PAHs). In relation to body weight, intake by children of most contaminants was higher than that found for other age groups of the general population of Catalonia.
