铝电解工业区儿童氟斑牙调查

Investigation on Dental Fluorosis Among Children in Industrial Area of Aluminum Electrolysis

目的 了解铝电解工业区儿童氟斑牙患病情况。方法 随机抽取某铝电解工业区2156名8～12岁儿童调查氟斑牙患病情况、尿中氟化物含量,同时进行环境介质中氟化物含量调查。结果 儿童氟斑牙患病率为51.1l％,尿中氟化物含量(1.44±0.96)mg/L。大气、农作物和土壤中氟化物含量均超过相应国家标准值或背景值,而饮用水源为低氟水源(0.065-0.823 mg/L)。结论该铝电解工业区的工业氟污染是儿童氟斑牙流行的主要原因。
