Respiratory function was measured in a cross sectional study of workers involved in the manufacture of rubber in order to study the prevalence of acute and chronic respiratory syndromes and lung function in workers occupationally exposed to aerosols in the rubber industry. The cross sectional portion of the study included 409 men working at one rubber manufacturing site. Their mean age was 36 years and the mean duration of exposure was 11 years, ranging from 1 to 30 years. A group of 311 of the 409 men were included in the followup study after a 6 year period of time. Their mean age at the first study was 35 years and the mean exposure was 11 years, range from 1 to 19 years. The prevalence of chronic respiratory symptoms in the 409 workers was significantly higher for all syndromes except for occupational asthma, than in a group of 172 controls. Smokers had significantly higher prevalence of all chronic respiratory symptoms than nonsmokers, except for occupational asthma and sinusitis. Those workers exposed for more than 10 years had significantly higher prevalence of symptoms except for occupational asthma. During the first follow up study, the prevalence was slightly and nonsignificantly higher during this period than during the first study. Acute reductions in ventilation capacity were noted in rubber workers over the work shift. All acute reductions were greater in workers exposed for more than 10 years and in smokers. The mean total dust concentration was very high at 33.1mg/m3 and the mean respirable fraction was 4.29mg/m3. These values exceeded significantly the maximal allowable concentration.
