The concentrations of As, Ag, B, Ba, Bi, Ca, Cd, Co, Cr, Fe, Ga, Hg, K, Li, Mg,Mn,Mo, Na, Ni, Pb, Rb, Sb, Se, Sn, Sr, Te, Ti,U, V and Znwere determined inwater and silverside (Odontesthes bonariensis)muscle samples fromfour importantcommercial fishing sites (Argentina) by ICPMS. Trace element concentrations in water with welldocumentedhuman health effects were above the recommended maximum levels established by Argentineanand international guidelines for the aquatic biota protection in three sampling sites (e.g. As: 28.4?367 μg L−1;Cd: 0.17?1.05 μg L−1; Hg: 0.07?0.63 μg L−1; Zn: 71.3?90.0 μg L−1). High concentrations of As, Hg and Pb(0.03?0.76; 0.03?0.42 and 0.04?0.19 mg kg−1 wetweight, respectively)were found in silverside muscle. Fishingcommunities associated with contaminated environments are likely to have higher consumption rates and arethus more likely to be exposed to higher concentrations of the toxic elements (As, Hg and Pb).
