尿液、头发、指(趾)甲高铊汞砷是铊矿区污染标志

Contaminative markers of TI-mining district from the high contents of Tl,Hg and As of urine hair and nail in the villagers

铊矿区村民尿液、头发和指（趾）甲中铊汞砷的含量高是矿区和村民受铊汞砷污染的标志，也是判别汞铊病的标志根据村民尿液中铊含量高低初步得出区别不同程度汞铊病患者的标准ＴＬ＞１０００×１０－９、１００×１０－９－１０００×１０－９和＜１００×１０－９分别为重汞铊病患者、轻汞铊病患者和非汞铊病者。人体和生物体中ＴＬ、Ｈｇ、Ａｓ含量高低与矿区岩矿石、土壤和水体中ＴＩ、Ｈｇ。

. The high contents of TI,Hg and As in urine, hair and nail (toenail) in the thallium mining district villagers areboth the indices for identifying the degree of contamination of the district caused by TI,Hg and As the markers for Hg-TIdiseases there.Based on the contents of TI in the villagers, urine, the preliminary criteria have been established for distinguishing seriously Hg-TI-diseased patients (Tl>1000×10-9), slightly Hg-Tl-diseased patients (100×10-9-1000×10-9)and normal inhabitants (<100 ×10-9). The contents of TI,Hg and As in human and organic bodies largely depend on thebackground values of these metals in rock,ore,soil and water
