通过现场试验及采自全省有关样品含碘量分析发现，贵州煤中含碘量较高，均值为３．６ｍｇ／ｋｇ；敞灶燃煤室内空气碘浓度为６．９μｇ／ｍ３；经过燃煤薰炕三个月的玉米和辣椒，含碘量分别为１１８．９μｇ／ｋｇ和７０２．３μｇ／ｋｇ；采自敞灶燃煤地区的陈玉米含碘均值高达１７７．０μｇ／ｋｇ，表明敞灶燃煤时，煤中的碘可释放于室内空气并富积于被薰炕的食物。这可能是贵州在外环境普遍缺碘的情况下，碘缺乏病主要分布在以柴为生活燃料的东南部地区的重要因素之一。
Through field test and analysis of iodine content of samples collected from the province, it is found that the content of iodine in Guizhou coal is higher with the average value of 3.6mg / kg; indoor air iodine concentration of coal in open-air stove is 6.9μg / m3; Coal and kang kang three months of corn and pepper, iodine content were 118.9μg / kg and 702.3μg / kg; coal mining area from open coal containing iodine average as high as 177.0μg / kg, indicating that the open When the stove burns coal, the iodine in the coal can be released into the indoor air and enriched in the smoked kang food. This may be one of the most important factors in the iodine deficiency disorders that are mainly distributed in the southeastern part of Guizhou where fuel is used as fuel for life in the absence of iodine in general.
