The concentrations of chromium, cobalt and nickel in 8 brands of Swedish cement, 19 detergents, 28 unused mould oils and 28 unused cutting fluids were determined by atomic absorption spectrophotometry. The total quantity of chromium in cement was 40-115 microgram Cr/g, whereas water-soluble chromium and chromate did not exceed 20 microgram Cr/g. The cobalt concentration was 5-16 microgram Co/g and the nickel concentration 5-59 microgram Ni/g. In detergents the nickel concentration was comparatively higher than that of chromium and cobalt. The highest value observed was 5.7 microgram Ni/g. In mould oils the concentrations were low, never exceeding 1 microgram/g. In cutting fluids the concentrations were low with the exeption of one product which contained 19.4 microgram Ni/g. The clinical implications of the results are discussed and it is pointed out that investigations of used cutting fluids can provide important information concerning possible allergy risks.
采用原子吸收分光光度法测定了8个品牌瑞典水泥、19种洗涤剂、28种未使用的模具油和28种未使用的切削液中铬、钴和镍的浓度。水泥中铬的总量为40 - 115微克铬/克，而水溶性铬和铬酸盐不超过20微克铬/克。钴浓度为5 - 16微克钴/克，镍浓度为5 - 59微克镍/克。在洗涤剂中，镍的浓度相对高于铬和钴。观察到的最高值为5.7微克镍/克。在模具油中，浓度较低，从未超过1微克/克。在切削液中，除一种产品含有19.4微克镍/克外，其他浓度较低。讨论了结果的临床意义，并指出对使用过的切削液进行调查可以提供有关可能的过敏风险的重要信息。
