氟、氯、溴、碘等卤族元素与人体健康的关系

RELATION BETWEEN HALOGEN GROUP ELEMENTS, F, Cl, Br, I AND HUMAN HEALTH

卤族元素是人体的必需元素，正常情况下成人摄入量不超过：F 4 mg/d、Cl 1.7～5.1 g/d、I 100～200μg/d；少年不超过F 3 mg/d，儿童I 1μg/kg－d，婴儿Cl 0.3～1.2 g/d。过量摄入或缺乏卤族元素，都可能导致疾病的发生。而F含量0.5～1.0mg/L、Cl＜50mg/L、Br＞100 μg/L、I 10～100μg/L的饮用地下水，有利于人体健康。

Halogen group elements are indispensable to human being, under normal condition, adult dosage below F 4 mg/d, Cl 1.7～5.1 g/d, I 100～200μg/d; youngster below F 3 mg/d; enfant I 1μg/kg per day; infant Cl 0.3～1.2 g/d. Excessive absorption or lack of halogen group elements could result in disease. Drinking groundwater, containing F 0.5～1.0mg/L, Cl＜50mg/L, Br＞100 μg/L, I 10～100μg/L, is beneficial to human health.
