This study analyzed the carapace distribution of Ca, Cd, Cr, Cu, Mg, Mn, Pb, Sb, U, V and Zn by GF-AAS and ICP-AES in one specimen of Caretta caretta from Mediterranean Sea. Calcium, Mg, Mn, Pb, U, Zn were mainly distributed in the central area while Cd, Cr, Cu, Sb, V in lateral areas. Cadmium, Cr, Mg, Mn, Sb, U and V were different between lateral areas. The different distribution may be related to several exposures during lifetime and/or the shell ossification during growth. Carapace may be a suitable matrix for metal biomonitoring, however, further studies are required to confirm these findings.
本研究采用石墨炉原子吸收光谱法（GF-AAS）和电感耦合等离子体发射光谱法（ICP-AES）分析了一只来自地中海的蠵龟（Caretta caretta）样本背甲中钙（Ca）、镉（Cd）、铬（Cr）、铜（Cu）、镁（Mg）、锰（Mn）、铅（Pb）、锑（Sb）、铀（U）、钒（V）和锌（Zn）的分布情况。钙、镁、锰、铅、铀、锌主要分布在背甲中央区域，而镉、铬、铜、锑、钒则分布在边缘区域。边缘区域的镉、铬、镁、锰、锑、铀和钒存在差异。这种不同的分布可能与蠵龟一生中的多种暴露情况和/或生长过程中的背甲骨化有关。背甲可能是一种适合进行金属生物监测的基质，然而，需要进一步的研究来证实这些发现。
