| 摘 要： | 川西高原是大骨节病比较集中的区域之一,低硒是大骨节病的重要致病因素,研究该地区硒含量对于防治大骨节病有重要意义。本文采用原子荧光光谱法研究川西高原阿坝地区大骨节病高发区水体样品中硒的含量特征。结果表明:该区域水体中硒含量较低,地下水的硒含量明显高于地表水和山泉水;山泉水的硒含量为0.001~0.058μg/L,平均值0.0067μg/L,硒的分布受地质背景、pH值和氧化还原电位(Eh值)等条件的控制,低硒的地质环境是导致山泉水的硒含量很低的最主要因素;地表水的硒含量为0.001~0.148μg/L,平均值0.0221μg/L,硒分布的影响因素为地质背景、地理条件以及水体地球化学条件;地下水的硒含量为0.001~0.210μg/L,平均值0.0523μg/L,硒分布的影响因素为地质背景、pH值和Eh值,有机质含量也是关键因素之一。研究认为,对于以山泉水为主要饮用水源的藏民,低硒的山泉水不能提供人体需要的硒营养,不适合作为水源;川西高原地表水资源丰富,但水中的元素迁移性极强,地表水中的硒不易进入生态链的循环,也不适合作为饮用水源;地下水的硒含量较高,应推广作为当地的生活饮用水,减少大骨节病的发病率。
