The endemic fluorosis in western Guizhou Province,southwest China was confirmed to be collected with high-content fluorine in topsoil (clay for coal-burning) of Hehua Village, Zhijin County,Guizhou Province ,which was considered to be closely associated with the long-term occurrence of endemic fluorosis. The new discovery in this article confirms that the mean value of apparent acidity of topsoil (pHa) in this village is 4.92;The measured average value of total sulfate radical was 4465μg/g. In addition, the apparent acidity and the content of total sulfate were positively correlated (correlation coefficient:0.7920).The result shows that the topsoil in this village is acidic and may belong to sulphation. |
