我们检测了南海大亚湾两颗庞特斯珊瑚生长带中的金属钙比（铁/钙、锰/钙和锌/钙），以追踪当地环境污染水平的长期趋势。尽管Fe和Mn在1976-2007年的32年间没有表现出明显的增长趋势，但Fe/Ca和Mn/Ca的峰值出现在20世纪80年代中后期。时间上与当地核电站的建设同时发生。此外，在过去 14 年（1994-2007 年）中，这两种珊瑚的锌浓度迅速增加，很可能是由于家庭和工业污水排放的增加。大亚湾珊瑚的金属浓度高于其他报告的来自原始和严重污染地区的珊瑚，这表明在过去大约 32 年里，当地发生了急性（铁和锰）和慢性（锌）重金属污染。 (C) 2010 Elsevier Ltd. 保留所有权利。
We examined metal-to-calcium ratios (Fe/Ca, Mn/Ca and Zn/Ca) in the growth bands of two Pontes corals from Daya Bay, South China Sea, in order to trace long-term trends in local ambient pollution levels. Although Fe and Mn did not show any obvious increasing trends over 32 years in the period 1976-2007, peak values of Fe/Ca and Mn/Ca occurred in the mid-late 1980s. temporally-coeval with the local construction of a nuclear power station. Furthermore, both corals showed rapid increases in Zn concentrations over the past 14 years (1994-2007), most likely due to increases in domestic and industrial sewage discharge. The Daya Bay corals had higher concentrations of metals than other reported corals from both pristine and seriously polluted locations, suggesting that acute (Fe and Mn) and chronic (Zn) heavy metal contamination has occurred locally over the past similar to 32 years.
