In an epidemiological study of metal workers exposed to ,metalworking fluids (MWF), the prevalence time of Evolution, seasonal occurrence and clinical type of con-tact dermatitis were investigated. Compostional analysis of MWF, with HPLC, dermatological examination and two consecutive questionnaire surveys ´´were conducted. Stud-y population was divided into two groups ; workers contact to cutting oil and worker-s contact to rust preventive oil. In the analysis of MWF, aliphatic+ hydrocarbons, having 12-20 carbons, was most common composition(49.04%) of cutting oil otherwise, major contents (90.99%) of the rust preventives oil were aliphatic hydrocarbons composed of 6-9 carbons. The frequency (point prevalence) of contact, dermatitis(CD) was 7(12.7 per 100 subjects) in the dermatological examination of 55 workers. As the result of second survey for contact dermatitis, cumulative prevalence of Oil working full-time and recent 1 year prevalence in two groups were 28.0, 16.7 and 15.1, 12.5 per 100 subjects. There were no difference in the prevalence of CD by oil, age, oil contact duration. Summer is the most common evolution season in workers´ exposed to cutting oil, but not in workers exposed to rust preventive oil. Major clinical type of CD was erythematous papules in both groups. It presents the importance of preventive measures that 51.1 % suffer from contact dermatitis had medical care at´ their own expense, and 47.1% of them felt serious about their contact dermatitis. From the fact that 68. 6% think cotton gloves protective apparatus, we emphasize the need for health education.
