| 摘 要： | 为探讨碘缺乏病区环境地质特征,通过对分布区不同类型岩(矿)石环境碘的地球化学特征,以及岩石系统中碘与钙、镁等元素相关性分析研究,认为贵州碘缺乏病分布与地层岩石碘的地球化学特征有关:病区主要分布于碳酸盐岩、碎屑岩以及浅变质岩碘背景含量较低的分布区,非病区主要分布于与煤、紫色岩碘含量较高分布区.分析结果显示:重(轻)病区岩石中钙及钙/碘值明显高于非病区岩石中钙及钙/碘值,而且钙、镁与碘呈负相关关系.

| Abstract: | In order to investigate environmental geology characters of iodine deficiency epidemic disease area in Guizhou province, iodine geochemistry in different rock (ore) type background and relativity of iodine with calcium and magnesium are analyzed. It is shown that distribution area of iodine deficiency epidemic disease in Guizhou province is related with iodine geochemistry of rocks (ores). Iodine deficiency epidemic disease areas are distributed in carbonate rocks, clastic rocks and epi-metamorphic rocks with lower iodine content, and rocks (ores) like coal and purple color rocks in non-disease area have higher iodine content. Calcium and calcium/iodine ratio in disease area are obviously higher that in non-disease area, and relativity between iodine and calcium, magnesium is a negative, showing that rock system environment plays an important role in deficiency epidemic disease. |
