This study presents the first report on the concentration of trace elements (Al, As, Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn) in the blood and egg fractions of green turtles from Rocas Atoll, a pristine nesting site in NE Brazil. The highest concentrations of all elements were in the blood or shell samples. In order, iron, Zn, Cu, Al and As presented the highest concentrations in all tissues. The nonessential trace elements were below the limit of detection for more than 50% of the yolk (Al, Cd and Pb) and albumen samples (Al, As, Ba, Cd and Pb). This study will serve as a baseline reference for future monitoring of the ecotoxicology of breeding green turtles in the southwestern Atlantic Ocean.

这项研究提出了关于Rocas Atoll绿海龟血液和卵中微量元素（Al，As，Ba，Cd，Cr，Cu，Fe，Mn，Ni，Pb，V和Zn）浓度的第一份报告，巴西东北部的原始巢穴。所有元素的最高浓度都存在于血液或贝壳样品中。因此，铁，锌，铜，铝和砷在所有组织中的浓度最高。对于超过50％的蛋黄（Al，Cd和Pb）和蛋白样品（Al，As，Ba，Cd和Pb），非必需痕量元素均低于检出限。这项研究将为将来监测西南大西洋海域绿海龟的生态毒理学提供基线参考。
