摘要
[目的]为松嫩平原饮水型地方性氟中毒的防治提供理论依据。[方法]分析了松嫩平原饮水型地方性氟中毒与土壤和地下水中氟的关系。[结果]东北地区饮水型氟中毒主要集中在大兴安岭东、西两侧的松辽平原和呼伦贝尔高平原。重病区及中病区主要分布在湖泊、沼泽洼地较多的冲积湖积平原区,地层主要为细粒度的黄土和淤泥质土,地下水类型主要为HCO3-Ca·Na型和HCO3·Cl-Na·Ca型,氟含量1.80-16.00mg/L,多为4-6mg/L;轻病和无病地区一般没有或较少有湖泊和沼泽洼地,地层主要为粗粒度的粉土和砂土,地下水类型主要为Cl-Ca·Na型和HCO3Cl-Na·Ca型,氟含量通常低于2mg/L。[结论]高氟地下水的形成与地质环境密切相关。
[Objective] This study aimed to investigate the fluorosis content in the groundwater of Songnen Plain and provide a theoretical basis for the prevention and control of endemic fluorosis in Songnen Plain. [Method] The relationship of drinking water type endemic fluorosis with the fluoride content in the soil and groundwater of Songnen Plain was analyzed. [Result] The endemic disease in this region is concentrated in the Song-Liao Plain and Hulunbuir Plateau on both sides of the Daxinganling Mountain. Severe and medium disease areas are distributed mainly in alluviallacustrine plains with dense depressions of lakes and marshes. The strata are commonly fine-grained loess and mucky soil. The groundwater is dominated by HCO3-Ca·Na and HCO3·Cl-Na·Ca types, with fluorine content of 1.80-16.00 mg/L, generally 4-6 mg/L. Light disease and non-disease areas are distributed in the alluvial-lacustrine plains with less or without depressions of lakes and marshes. The strata are mainly coarse-grained silty soil and sandy soil. The chemical types of ground water are Cl-Ca·Na and HCO 3 Cl-Na·Ca. The content of fluorine in ground water is commonly lower than 2 mg/L. [Conclusion] High fluorine groundwater formation is closely related to the geological environment.
