研究了菏泽市苏家村饮用水中F、Ca、Cu、Fe、Mo、Zn含量与地氟病的关系。结果表明:苏家村7～13岁儿童氟斑牙患病率为95%,水中氟平均含量为3.79 mg/L;沙山寺村儿童氟斑牙患病率为2%,水中氟平均含量为1.03 mg/L。因此苏家村儿童氟斑牙患病率高主要由饮用水中氟含量严重超标所致。此外饮用水中Ca、Mo会抑制人体对氟元素的吸收,从而降低氟斑牙的患病率;而Cu、Fe、Zn含量对当地氟斑牙的发生影响不明显。
The relationship between F, Ca, Cu, Fe, Mo and Zn in drinking water and ground fluorosis in Suji, Heze City was studied. The results showed that the prevalence of dental fluorosis in children from 7 to 13 years old in Suji village was 95%, and the average fluorine content in water was 3.79 mg / L. The prevalence of dental fluorosis in Shashan Temple was 2% and the average fluorine content in water was 1.03 mg / L. Therefore, the prevalence of dental fluorosis in children in the village of Su mainly caused by serious excessive fluoride content in drinking water. In addition, drinking water Ca, Mo will inhibit the body’s absorption of fluoride, thereby reducing the prevalence of dental fluorosis; and Cu, Fe, Zn content on the occurrence of local dental fluorosis was not obvious.
