Ten chromite miners in South Africa have been found to show radiological evidence of a fine nodulation; five of these miners had worked only in chromite mines. These cases occurred in a labour force of some 1,500 persons subjected to regular examination. Clinical evidence and the results of intratracheal injection of chromite suspension into rats indicate that the radiological changes are due not to fibrosis but to a benign deposition of chromite (CrOFeO) dust in the lungs.
在南非，已发现10名铬铁矿矿工有细微结节的放射学证据；其中5名矿工仅在铬铁矿工作过。这些病例出现在约1500名接受定期检查的劳动力中。临床证据以及向大鼠气管内注射铬铁矿悬浮液的结果表明，放射学变化并非由纤维化引起，而是由于铬铁矿（CrOFeO）粉尘在肺部的良性沉积。
