饮茶型氟中毒——四川省阿坝藏族自治州壤塘县地氟病调查

A NEW TYPE OF FLUORINE POISONING CAUSED BY DRINKING THE BRICK TEA

众所周知,茶叶氟含量是很高的,饮茶能否引起慢性氟中毒?这是氟病学界极为关心的问题。1963年报道了越南北方蔬菜和茶叶引起当地氟斑牙流行,但国外有关这方面的文献甚少,国内尚未见报道。我们在1983年对壤塘县进行地氟病流行病学调查时,注意到病区的形成与藏族饮用砖茶的生活习惯有关。为此。

This report describes a new ki-nd of endemic fluorine poisoning c-aused by drinking of the brick teawhich contains high fluorine conte-nt((?)±SD=622.5±155.57mg/kg)am-ong the Tibetan inhabitants lived inRangtang country,Aba AutonomousRegion,Sichuan Provionce.The prev-alence of dental mottling was 72.64%and the prevalence of skeletal fluo-rosis examined by X-rays was 97.14% in these native Tibetans.The f-luorine contents in drinking water,food,atmosphere,and salt in theendemic area were nearly the sameas in the control areas,while its co-ntent in the brick tea water was v-ery hign((?)±SD=2.76±0.36ppm). The average fluorine intake per p-erson per day was 14.21mg whichwas estimated as 91.49% of thetotal intake of fluorine.This surveydiscovered a new type of fluorinepoisoning resulted from drinkingthe brick tea in large amount overa long period。
