十余年来,在开展地方性疾病的病因研究中已进一步证明,环境地球化学在研究和阐明自然环境中所发生的地球化学现象与其他自然要素间的相互关系以及在探索地壳中化学物质的迁移、转变和聚集与生物生态和人类活动的关系,起到了日益重要的作用。 环境质量模型,是在环境地球化学调查的基础上,用以反映环境中各种客观要素与地 More than a decade of research into the etiology of endemic diseases has further demonstrated the relevance of environmental geochemistry in the study and elucidation of the interrelationships between the geochemical phenomena occurring in the natural environment and other natural elements and the exploration of chemical substances in the crust Migration, transformation and aggregation of biological ecology and human activities, has played an increasingly important role. Environmental quality model is based on the survey of environmental geochemistry, to reflect the environment in a variety of objective elements and
