地方性氟中毒是生物地球化学性疾病之一,饮水含氟量的高低与地方性氟中毒的发病有着密切的关系,为了掌握冀县饮水含氟量的情况,从1988—1989年,我们对全县的饮水井含氟量及井深进行了普查,探讨了含氟量与井深的关系,报告如下: 1 方法与结果 检验方法:茜素磺酸锆比色法。 我国饮水含氟量标准:不超过1.0mg/L,适宜浓度为0.5～1.0mg/L。 检验结果:在所检验的349眼饮水井中,最低含氟量为0.2mg/L,最高含氟量为2.8mg/L,含氟量符合国家饮水标准的占75.6％,超过国家标准的占24.4％。
Local fluorosis is one of the biogeochemical diseases, the level of fluoride in drinking water and the incidence of endemic fluorosis are closely related, in order to grasp the fluorine content of drinking water in Ji County, from 1988 to 1989, we The drinking water in the county fluorine content and depth of the census, discussed the relationship between fluorine content and well depth, the report is as follows: 1 method and results of the test method: Zirconium sulfonate colorimetric method. China drinking water fluoride content standards: not more than 1.0mg / L, the appropriate concentration of 0.5 ~ 1.0mg / L. Test results: Among the 349 drinking water wells examined, the lowest fluorine content was 0.2 mg / L, the highest fluorine content was 2.8 mg / L, and the fluorine content was 75.6% in line with the national drinking water standard, accounting for 24.4 more than the national standard %.
