BACKGROUND: Chrome has been known to be a toxic and poten sensitizer and is contained in materials with which we are in frequent contact. But we have few reports detailing chrome contact dermatitis by clothes or the chrome content of materials in out use. OBJECTIVES: Our purpose was to evaluate the chrome content in rassieres. METHODS: We analyzed chrome in brassieres by using atomied absorption spectrophotometer, quantitatively and diphenylcarbazide method, qualitatively. RESULTS: The content of chrome in a 24 hour saline extracted g roup, a 48 hour saline extracted group and a pure nitric acid extracted group in the black was more abundant than in the reds or in the whites. But there was no aignificant difference in the different fabrics of the blacks. CONCLUSION: Although, in reality, it is hard to change chrome to an other substrate as the mordant of dyes, a limitation needed to prevent diseases induced by chrome during the process of dyeing. If someone has a sensitivity to chrome, it is necessary to wash new clothes before waring and to avoid black colored underwear.
