| 中文摘要 |
| 为了探明石煤暴露环境中发氟含量的分布规律及影响因子,结合病情调查,采集发样进行元素含量测定.结果表明,石煤暴露环境发氟含量个体差异显著,呈非正态分布,平均值为67.08±64.68μg/g,变异系数为96.42%;发氟含量同Ca、Mn、Se的含量呈显著正相关,同Ti含量呈显著负相关;因子分析显示发氟含量分布除受体内生化反应控制外,与表生地球化学环境、膳食结构以及饮用水的水质等因子也密切相关. |
| 英文摘要 |
| To find out the distribution pattern of hair fluoride and its affected factors in coal exposed environment, human hairs were collected according epidemiological investigation, and contents of fluoride and other life relative elements in the samples were determined. Results shown that the fluoride content in human hairs had a notable individual differen-tia, its distribution pattern was anomalous distribution with average fluoride content 67.08±64.68μg/g and coefficient of variation 96.42%. There were significant positive correlation between F and Ca, Mn, Se as well as significant negative correlation between F and Ti. Factor analysis shown the fluoride content in human hairs was affected by factors such as inner biochemical reaction, outer geochemical environment, structure of food web and quality of drinking water. |
