The historical mercury accumulation rates (Hg AR) resulting from atmospheric deposition to Xiaoxing'an Mountain were determined via analysis of (210)Pb- and (14)C-dated cores up to 5000 years old. Natural Hg AR background, pre-industrial Hg AR and maximum industrial Hg AR in Northeast China were 2.2 ±1.0 μg/m(2)/yr for 5100-4500 BP, 5.7 μg/m(2)/yr and 112.4 μg/m(2)/yr, respectively. We assumed that the increase in Hg deposition in the Xiaoxing'an mountain area during industrial time was mainly attributed to local anthropogenic emissions around this peat bog.
通过对长达 5000 年的（210）Pb 和（14）C 定年的核心进行分析，确定了来自大气沉积的小兴安岭历史汞积累率（Hg AR）。小兴安岭地区的自然 Hg AR 背景值、前工业化 Hg AR 和最大工业化 Hg AR 分别为 5100-4500 BP 的 2.2±1.0μg/m(2)/yr、5.7μg/m(2)/yr 和 112.4μg/m(2)/yr。我们假设，小兴安岭地区在工业化时期汞沉积的增加主要归因于该泥炭沼泽周围的当地人为排放。
