中文摘要：

用电感耦合等离子体质谱（ICP-MS）等方法，对贵州省凯里下二叠统梁山组高硫煤中Be、P、Sc、Mn、Co、Ni、Cu、Mo、TI、Pb、Th和U等12种有害微量元素进行了测定。结果表明，凯里煤中多数有害微量元素含量明显高于中国煤中微量元素含量平均值。根据数理统计结果，将凯里煤中22种微量元素划分为5个群和4个旋转主因子，其中群5元素Be和Y对4个主因子均无贡献，暗示其成因来源可能具有特殊性。认为凯里煤中相当一部分Be、Co、Cu和Pb起源于成煤植物生长期间的同生阶段；受海水影响强烈的还原偏碱性沼泽环境有利于Be、Co和Cu的相对富集，受海水影响微弱的弱还原性和弱碱性环境条件更有利于Mn、Mo、1Ni、P、Pb、Th、TI和U的富集。

英文摘要：

The contents of twelve hazardous trace elements such as Be, P, So, Mn, Co, Ni, and U and other trace elements in the high-sulfur coal seam of Lower Permian eastern Guizhou were determined using inductively coupled Liangshan Cu, Mo, TI, Pb, Th Formation from Kaili, plasma mass spectrometry （ICP-MS）. The results show that the contents of most trace elements in Kaili coal are higher than the average contents of those elements in China coals evidently. Based on the results from mathematic statistics, the twenty-two trace elements in Kaili coal can be divided into five clusters and four rotated main factors. Cluster 5, being composed of Be and Y, made no contribution to the four main factors, indicating an especial source for Be and Y. It is suggested that quite a lot of the Be, Co, Cu and Pb could be originated from the syngenetic stage during which the coal-forming plants grew. The strongly seawater-effected peat bog with the reductive and alkaline water could be in favor of the relative enrichment of the Be, Co and Cu, and the faintly seawater-effected bog with the slightly reductive and alkaline water could be in much favor of the enrichment of the Mn, Mo, Ni, P, Pb, Th, TI and U.
