本文通过对巫山燃煤污染氟病区和石柱克山病区的几种样品进行硒检测，两个地区的硒含量呈显著性差异，探讨了燃煤污染对人体硒水平的影响，为降低燃煤污染的工作会不会引起人体硒含量的改变提供线索。
In this paper, the selenium content of selenium in two areas were tested by selenium test on several samples of fluorine-contaminated area and Shizike-Karst area of Wushan coal-burning area. The selenium content in two areas was significantly different. The influence of coal- Coal pollution will lead to changes in human selenium content provide clues.
