通过对贵州土壤氟元素地质背景调查,结合以往的地氟病环境调查分析成果,并对贵州1:20万化探扫面成果数据进行统计分析,结果显示,贵州土壤与中国土壤及世界部分国家土壤相比,氟含量明显具有高氟背景特点,并且西部地氟病严重分布区土壤氟含量明显高于东部。认为贵州燃煤引起氟中毒应充分考虑土壤高氟背景这一重要影响因素。
Through the investigation on the geological background of fluorine in Guizhou soil and the previous environmental survey of ground fluorosis, the data of 1: 200000 geochemical exploration in Guizhou were statistically analyzed. The results showed that there was no significant difference between Guizhou soil and soils in China and some countries in the world Compared with the soil, the fluorine content obviously has the characteristics of high fluoride background, and the content of fluoride in the soil in the serious distribution area of fluorine in the west is obviously higher than that in the east. Fluoride poisoning caused by coal combustion in Guizhou should fully consider the background of high fluoride in soil, an important factor.
