本文对赤峰市土氟分布规律及其与氟中毒病情关系进行了研究。结果表明,土中水溶氟是氟病区形成的主要氟源,其进入人体的主要载体是饮水,从而确定该市病区为饮水型;土中水溶氟含量增高,导致氟病区形成,其增高的原因,是微地貌所控制的封闭式水平径流条件和细粒土所构成的滞留式垂直径流条件,加干旱气候条件。据上述病区成因观点,本文提出了相应的防氟对策。
In this paper, the distribution of soil fluoride in Chifeng City and its relationship with fluorosis was studied. The results showed that water-soluble fluoride in soil was the main source of fluorine formed in the ward, and its main carrier into the human body was drinking water, which confirmed that the ward of the city was of drinking water type. The reason for the increase is the closed horizontal runoff conditions controlled by micro-topography and the retention-type vertical runoff conditions formed by fine-grained soil, plus the arid climatic conditions. According to the causes of the above ward, this paper presents the corresponding anti-fluoride measures.
