1. In the past workers in refineries had a high prevalence of respiratory symptoms,"'" and asthma and rhinitis remain current problems.'" The present study was possible because of the introduction of skin prick tests with common environmental allergens into the pre-employment medical examination in a refinery, which started in 1973 as an objective test for atopy; from 1975 atopic workers were excluded from refinery work." A preliminary study of the 1973-4 cohort showed an increased incidence of occupational allergy in atopic workers but did not examine smoking
