滥术厂铊矿区是一个天然铊污染和铊中毒的典型实例。矿床开发利用导致铊进入表生环境,由于含铊岩矿石的风化淋滤作用,使溶解铊进入地表水体、土壤、植物和人体生态链,故尔引起铊环境污染和慢性铊中毒出现。根据矿区水中铊含量将矿区水分为四种类型:①安全饮用水(<1×10-9);②可饮用水[(1~5)×10-9];③非饮用水[(5~10)×10-9];④污染水(>10×10-9)。建议中国饮用水中铊含量1×10-9定为安全即无毒害标准。
Abuse plant thallium mine is a typical example of natural thallium pollution and thallium poisoning. The development and utilization of the deposit leads to the thallium entering the supergene environment. Due to the weathering and leaching of the thalliferous ores, thallium dissolves into the surface water bodies, soil, plants and the human ecological chain, thereby causing the thallium environmental pollution and the chronic thallium poisoning to occur. According to the content of thallium in the mining area, the water in the mining area will be divided into four types: ① safe drinking water (<1 × 10-9); ② potable water [(1 ~ 5) × 10-9]; ③ non-potable water [ 10) × 10-9]; ④ contaminated water (> 10 × 10-9). It is suggested that the content of thallium in Chinese drinking water 1 × 10-9 be safe or non-toxic standard.
