铅（Pb）是环境中典型的重金属污染物，大部分Pb污染来自人类活动。本文测定了两种黑珊瑚（Cirrhipathesspp.）采用同步辐射微区X射线荧光（SR μ-XRF）分析方法，对南海北方海域的100个样品进行了分析。结果表明，来自三亚湾（靠近大陆）的样品SY-1比来自西沙群岛（远离大陆）的样品XS-1显示出更高的铅含量和更大的波动，反映了陆地输入和大气沉积对沿海表层海水的影响。研究结果还表明，近岸海域黑珊瑚中铅的分布受人类活动的影响较大，主要受战争和经济发展的影响。因此，利用SR μ-XRF分析技术，黑珊瑚有可能成为一种新的潜在的环境铅记录物。
Lead (Pb) is a typical heavy metal pollutant in the environment, and most Pb contamination comes from human activities. In the present work, the Pb contents of two black coral specimens (Cirrhipathesspp.) collected from the northern South China Sea were measured by synchrotron radiation micro X-ray fluorescence (SR μ-XRF) analysis with 2.5 μm resolution. The results showed that sample SY-1 from the Sanya Bay (near the continent) exhibited higher Pb levels and greater fluctuations than sample XS-1 from the Xisha Islands (off the continent), reflecting the influence of terrestrial input and atmospheric deposition in coastal surface seawater. The present work also demonstrated that the Pb profile in black coral nearshore was highly influenced by human activities, mainly by war and economic development. Thus, black coral may serve as a new potential environmental Pb recorder with SR μ-XRF analytical technology.
