神农架松柏镇水文地球化学研究

Hydrogeochemical Characteristics in Shennongjia Forest Region,Songbo Town,Hubei Province

近年来,神农架松柏镇居民的结石病时有发生,并有增长的势头。为了解地质环境尤其是饮用水对病患的影响,笔者现场对患病情况以及各种水源(包括河水、泉水、自来水)的来源、化学组成和放射性进行了调查,运用水质常规方法和原子吸收光谱分别测定了离子和微量元素。同时,与地质环境类似的木鱼镇进行了对比调查。研究结果显示,两地地表水、地下水的各种指标均未超出"生活饮用水水源水质卫生标准"。(CJ3020 93),且松柏镇水体中的放射性(γ射线)低于木鱼镇,而居民的患病率却远高于木鱼镇,可见松柏镇的水环境与居民的结石病无直接关系。

In recent years, the calculus happen occasionally in Songbo Town, the capital of Shennongjia forest district, and has a trend to be more and more frequent. In order to find out the relation between geoenvironment (especially drinking water) and the disease, the authors investigated the ill situation and some characters of drinking water at the scene,such as the source, chemical composition and radioactivity of all the drinking water (including river, spring water,and running water) . We used routine methods to analyse major ions and atom spectrum to analyse trace elements. Investigation was also made in Muyu Town for comparison. The result shows that all the indexes of surface water & ground water in the two towns have not gone beyond the <Water Quality Standard for Drinking Water Source>(CJ3020-93).Water radioactivity (γ ray) in Songbo Town is higher than that in Muyu Town, however, the resident's ill rate in Songbo Town is higher than that in Muyu Town. So, we can conclude that there is no direct relation between the disease and water environment.
