摘要
为探讨贵州碘缺乏病与环境的关系,以及环境中岩石、土壤和水对碘缺乏病分布的影响因素,对贵州碘缺乏病的重病区、轻病区和非病区进行了一定量的岩石、土壤、水及粮食作物(大米和玉米)样品采集,测试碘背景含量,并进行对比分析。结果显示,环境中岩、土及水碘背景与贵州碘缺乏病分布有一定的关系。重病区主要属岩石、土壤和水碘背景含量低的分布区,其岩石类型主要为碳酸盐岩;非病区主要属岩石、土壤和水碘背景含量相对较高的分布区,其岩石类型主要为煤系;轻病区分布的岩石、土壤和水碘背景含量则介于重病区和非病区之间,其岩石类型主要为浅变质岩和碎屑岩。
In order to discuss the relations between the iodine deficiency epidemic disease and the environment as well as the factors of rock, soil and water affecting iodine deficiency epidemic disease in Guizhou Province, the authors carried out sampling and analysis of rocks, soils, water and crops (rice and corn) in different epidemic disease areas, including heavy disease areas, light disease areas and non-disease areas, tested the background contents of iodine, and performed comparative analysis. It is shown that the background iodine in rocks, soils and water were somewhat related to the distribution of iodine deficiency disease in Guizhou. The heavy disease areas were mainly distributed at carbonate rock areas, with low background iodine in rocks, soils and water; the non-disease areas were mainly distributed coal series rock areas, with relatively high background iodine in rocks, soils and water; the light disease areas were mainly distributed at epizonal and fragmentary rock areas, with background iodine in rocks, soils and water between those of heavy disease areas and non-disease areas.
