微量元素与地方性氟中毒关系的调查研究

Investigation of relationship between microelement and endemic fluorine poisoning

本文对地方性饮水型氟中毒病区饮水、学龄儿童头发、相邻非病区水样及高碘(水碘100μg/L 以上)地区水样调查的分析,结果表明饮水型氟中毒与饮水含氟量有密切关系,水氟发氟与氟斑牙患病率大致呈平行趋势,水氟达1.5mg/L 以上氟斑牙患病率明显上升(50%以上),当水氟在1mg/L 以下的病区,碘高患病轻,碘低患病重,而水氟高(3mg/L 以上)地区,碘高患病反而加重,碘低患病轻,差异显著;当水氟在2mg/L 以上,氟含量水平接近的病区,饮水中钼或钼/氟比值越高患病越轻;凡重的病区水钼或钼/氟比值均偏低;同时发现饮水中铜/钼的比值变化也影响本病。

This paper relates to investigative analysis for drinking water in the endemicfluorine poisoning area,nondisease area and high iodine area.The resultshows that fluorine and fluorine poisoning are closely related,ratio values ofMo and Mo-F or Mo-Cu is increased in drinking water,where the illnesswould be reduced,but in high-F area the iodine content is increasing,theillness would become worse.
