采集了南海永乐群岛金银岛、金青岛和广金岛的3条鸟类成因珊瑚砂沉积剖面，重建了研究区近700年的人为汞沉积通量。总体而言，人为汞通量较低；工业革命前一直处于较低水平，并在公元1450-1550年左右出现一个小高峰，这可能记录了中国明代冶金活动的增强。 20世纪期间，人为汞沉积通量迅速增加，但在1940年代和1970年代左右出现了两个低谷，分别对应于二战、中国内战（1945-1949）和文化大革命（1966-1976）造成的经济萧条。 20世纪70年代以来，人为汞沉降通量持续增加，这显然是南海周边东亚和东南亚国家经济快速发展的结果。 (C) 2012 Elsevier Ltd. 保留所有权利。
We collected three ornithogenic coral sand sedimentary profiles from Jinyin Island, Jinqing Island and Guangjin Island of Yongle archipelago, South China Sea and reconstructed the deposition flux of anthropogenic Hg over the past 700 years in the study area. On the whole, the anthropogenic Hg flux is relatively low; it remained at a low level before the Industrial Revolution with a small peak at about 1450-1550 AD, which may record the enhanced metallurgy activity in Ming Dynasty of China. During the 20th century, the deposition flux of anthropogenic Hg increased rapidly, but two troughs occurred during the periods around 1940s and 1970s, corresponding to the economic depression caused by World War II, Civil War in China (1945-1949), and the Culture Revolution (1966-1976) in China. Since the 1970s the deposition flux of anthropogenic Hg has been persistently increasing, apparently the result of fast economic development in East and Southeast Asia countries around South China Sea.
