Using a sensitive ETA ASS method, urinary thallium (Tl-U) has been measured in a group of non-exposed individuals and in two groups of workers with suspected industrial exposure. In non-exposed subjects (72 healthy males aged 41 +/- 11 years) the Tl-U mean value was 0.22 mu/l (range 0.05-0.61). Significantly higher values were found in two groups of workers (30 and 21 subjects) employed in two cement factories and two cast iron foundries (mean Tl-U value: 0.38 and 0.33 mu/l, respectively; range 0.06-1.2). Thallium has been determined in coal, raw materials and, in one factory, also in environmental samples, but no detectable levels were found. The analytical problems connected to urinary thallium determination and the preliminary results of biological monitoring in non-exposed individuals and in workers are discussed.
采用一种灵敏的ETA ASS方法，对一组未接触铊的个体以及两组疑似有工业铊接触史的工人的尿铊（Tl-U）进行了测定。在未接触铊的受试者（72名年龄为41±11岁的健康男性）中，尿铊的平均值为0.22 μ/l（范围为0.05 - 0.61）。在两家水泥厂和两家铸铁厂工作的两组工人（分别为30名和21名受试者）中，发现尿铊值明显更高（尿铊平均值分别为0.38和0.33 μ/l；范围为0.06 - 1.2）。已对煤、原材料进行了铊含量测定，并且在一家工厂还对环境样本进行了测定，但未检测到铊含量。讨论了与尿铊测定相关的分析问题以及未接触铊个体和工人的生物监测初步结果。
