The concentration of total urinary chromium (Cr-U) in two different groups of healthy occupationally non-exposed subjects living in the Italian regions of Lombardia and Veneto has been determined using an ETA-AAS direct method. The age, sex, residence and smoking habits were correlated with CrU excretion. The mean CrU value found in subjects living in Lombardia (n = 310, males 170 and females 140) was 0.59 + 0.26 microgram/l (range 0.08 - 2.10); in Veneto subjects (n = 238, males 187 and females 51) the mean value was 0.52 +/- 0.31 microgram/l (range 0.05 - 1.90). A significative difference between male and female values and a decrease of CrU levels with age increasing have been evidenced in both groups. Smoking habits seem to influence metal urinary levels while, on the other hand, no influence of living sites was observed. Some analytical problems of ETA-AAS Cr determination systems are discussed and "normal" CrU values measured in this study are compared with data reported in the literature.
采用电热原子吸收光谱法（ETA-AAS）直接测定法，测定了居住在意大利伦巴第大区和威尼托大区两组不同的职业非接触健康受试者的尿总铬（Cr-U）浓度。研究了年龄、性别、居住地和吸烟习惯与尿铬排泄量的相关性。居住在伦巴第大区的受试者（n = 310，男性170名，女性140名）的平均尿铬值为0.59±0.26微克/升（范围0.08 - 2.10）；威尼托大区受试者（n = 238，男性187名，女性51名）的平均值为0.52±0.31微克/升（范围0.05 - 1.90）。两组均显示男性和女性的尿铬值存在显著差异，且尿铬水平随年龄增长而降低。吸烟习惯似乎会影响尿中金属含量，而居住地则无影响。讨论了ETA-AAS铬测定系统的一些分析问题，并将本研究中测得的“正常”尿铬值与文献报道的数据进行了比较。
