Copper (Cu) is a transition metal and an essential micronutrient for organisms, but also one of the most widespread toxic inorganic contaminants at very high content. The research on Cu isotopes has grown rapidly in the last decade. Hitherto, a large number of studies have been published on the theoretical fractionation mechanisms, experimental data and natural variations of Cu isotopes in variable environments and ecosystems. These studies reported a large variation of δCu (-16.49 to +20.04‰) in terrestrial samples and showed that Cu isotopes could be fractionated by various biogeochemical processes to different extent. Several papers have previously reviewed the coupling of Cu and Zn isotope systematics, and we give here a tentative review of the recent publications only on Cu isotopesin variable surface repositories, animals and human beings, with a goal to attract much attention to research on Cu (and other metals) behaviors in the environment and biological systems.
铜（Cu）是一种过渡金属，是生物体必需的微量营养素，但在含量极高时也是分布最广泛的有毒无机污染物之一。在过去十年中，关于铜同位素的研究发展迅速。迄今为止，已经发表了大量关于不同环境和生态系统中铜同位素的理论分馏机制、实验数据和自然变化的研究。这些研究报告了陆地样品中δCu（-16.49至+20.04‰）的巨大变化，并表明铜同位素可通过各种生物地球化学过程在不同程度上发生分馏。此前已有多篇论文对铜和锌同位素体系的耦合进行了综述，在此我们仅对近期关于可变地表储库、动物和人类中铜同位素的出版物进行初步综述，目的是吸引更多人关注铜（以及其他金属）在环境和生物系统中的行为研究。
