Micropogonias furnieri and Urophycis brasiliensis are two coastal demersal fish species distributed in the southwestern Atlantic Ocean. Considering that many coastal areas in the southwestern Atlantic Ocean suffer from anthropogenic pressure, the aim of this study was to assess the level of potentially toxic trace elements (Ag, Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Se, Sr, V and Zn) in the muscle of coastal species, and evaluated the human health risk related to the consumption of muscle. Mercury, inorganic As (As), V, and Se showed a higher contribution to the total THQ. Considering two possible scenarios, As represents 1 % or 5 % of the total As, the total THQ was <1 for general population and of some health concerns for fishermen population (Total THQ > 1; 5 % As). Consequently these results show the importance of quantifying As species in muscle to generate more reliable risk estimates for human health.
黄鳍美洲拟鲽和巴西无须鱚是分布在西南大西洋的两种近岸底层鱼类。考虑到西南大西洋的许多沿海地区都受到人为压力的影响，本研究旨在评估沿海物种肌肉中潜在有毒痕量元素（Ag、Al、As、Cd、Co、Cr、Cu、Fe、Hg、Mn、Mo、Ni、Pb、Se、Sr、V 和 Zn）的水平，并评估与肌肉消费相关的人类健康风险。汞、无机砷（As）、V 和 Se 对总 THQ 的贡献较高。考虑到两种可能的情况，当 As 占总 As 的 1%或 5%时，普通人群的总 THQ<1，但对于渔民人群存在一些健康问题（总 THQ>1；5% As）。因此，这些结果表明，在肌肉中定量分析 As 物种对于生成更可靠的人类健康风险估计具有重要意义。
