| 摘 要： | 根据现有的资料,得出中国不同地区煤中微量元素的背景值。由于分析样品分布不均和采用的测试方法各不相同,本文的数据还不能准确地代表中国煤中微量元素的平均丰度值。另外,我国不同地区、不同时代和不同地质背景下形成的煤层煤中微量元素丰度差异很大,必须从元素的资源化利用及其环境效应方面来分析元素的丰度。含量异常的元素要特别加强研究。进一步的测试和研究有助于更加全面地了解我国煤中微量元素的分布情况、地质成因及其对环境的潜在影响。

| Abstract: | According to the strata about the trace elements in coal of China,the different background value of trace elements in different parts of China were d rew out.However these can't be taken as the real background value of abundance f or trace elements because of the lack of representative of samples.There is big difference on the abundance of trace elements in different coals of China,and i t is important to pay attention to the utilization and environmental impacts of trace elements.However unusual high concentration of toxic elements in coal shou ld be deeply researched so as to assess their potentials impacts on environment. |
