Concentrations of elements (As, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sr, V, Zn) were determined in liver, kidneys and bones of Eretmochelys imbricata and Chelonia mydas specimens found stranded along the northern coast of Bahia, Brazil. Results showed that the concentrations of Cd, Cu, Ni and Zn in the liver and kidneys of juvenile C. mydas were the highest found in Brazil. We also observed a significant difference (p<0.05) on the bioaccumulation of trace elements between the two species: Al, Co, Mo, Na and Se in the liver; Al, Cr, Cu, K, Mo, Ni, Pb, Sr and V in the kidneys; and Al, Ba, Ca, Cd, Mn, Ni, Pb, Se, Sr and V in the bones. This study represents the first report on the distribution and concentration of trace elements in E. imbricata in the Brazilian coast.
测定了巴西巴伊亚北部沿海搁浅的玳瑁(Eretmochelys imbricata)和绿海龟(Chelonia mydas)的肝脏、肾脏和骨骼中的元素(As、Al、Ba、Ca、Cd、Co、Cr、Cu、Fe、Hg、K、Mg、Mn、Mo、Na、Ni、Pb、Sb、Se、Sr、V、Zn)浓度。结果表明，幼年绿海龟肝脏和肾脏中的 Cd、Cu、Ni 和 Zn 浓度是巴西最高的。我们还观察到两种物种之间痕量元素生物累积的显著差异(p<0.05)：肝脏中的 Al、Co、Mo、Na 和 Se；肾脏中的 Al、Cr、Cu、K、Mo、Ni、Pb、Sr 和 V；骨骼中的 Al、Ba、Ca、Cd、Mn、Ni、Pb、Se、Sr 和 V。本研究首次报道了巴西沿海玳瑁体内痕量元素的分布和浓度。
