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 Zn were determined in water and silverside (Odontesthes bonariensis) muscle samples from four important commercial fishing sites (Argentina) by ICPMS. Trace element concentrations in water with well-documented human health effects were above the recommended maximum levels established by Argentinean and 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) wet weight, respectively) were found in silverside muscle. Fishing communities associated with contaminated environments are likely to have higher consumption rates and are thus more likely to be exposed to higher concentrations of the toxic elements (As, Hg and Pb).
采用 ICPMS 法测定了来自阿根廷四个重要商业捕捞区的水样和银鲈（Odontesthes bonariensis）肌肉样本中的 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 和 Zn 等元素的浓度。在三个采样点，水样本中具有明确记录的人类健康影响的微量元素浓度超过了阿根廷和国际水生生物保护指南规定的推荐最高水平（例如，As：28.4-367μg/L；Cd：0.17-1.05μg/L；Hg：0.07-0.63μg/L；Zn：71.3-90.0μg/L）。在银鲈肌肉中发现了高浓度的 As、Hg 和 Pb（分别为 0.03-0.76、0.03-0.42 和 0.04-0.19mg/kg 湿重）。与污染环境相关的渔业社区可能具有更高的消费率，因此更有可能接触到更高浓度的有毒元素（As、Hg 和 Pb）。
