青海贵德地区地方病与生态地质环境研究

Endemic Diseases and Ecological Geological Environment in Guide Area

为了查明青海贵德地区地方病高发的原因,通过对贵德地区、平安健康区,兴海病区土壤、植物、水体、人发各介质的综合对比研究,认为研究区Se在土壤、植物、水、人发中均低于平安健康区,营养元素的缺乏可能成为一些疾病的发生的原因。研究区As、F在人发中的含量较高,相应的是水体中这两个元素的高含量,而在土壤和小麦样品中As、F的含量与对比区无异。推测贵德地区地方病的致病原因,主要是饮用了当地高F、As的地下水。

For the sake of Guide region in a high incidence of endemic diseases,we have made a sincere research of the soil,plants,water,human beings under the average level,including a comprehensive comparation in nutrient element in each medium.We have found that Se in the soil,plant,water in the area is lower than in human health area.The lack of nutrients may be some reasons of the occurrence of diseases.In our study,the content of As and F in human hair is relatively high,which corresponds to the high content of these two elements in water,while the content of As and F in soil and wheat samples is not different from that in the comparison area.It is speculated that the main cause of endemic diseases in guide area is drinking groundwater with high F and As.
