Étude sur les changements respiratoires aigus chez les travailleurs des salles de cuves de l'industrie primaire de l'aluminium (Complexe industriel de Jonquière)

Acute respiratory changes have previously been observed in aluminium potroom workers. The main purposes of this study were to determine the prevalences of such changes amongst potroom workers assigned respectively to either one of the plant electrolytic processes, namely the Soderberg and the Prebake, and to compare the prevalence in each exposure group to that in unexposed workers of the same plant. Pulmonary function tests were administered four times on the first working shift of the week to 385 of the 412 subjects who had also answered a respiratory symptoms questionnaire. An index of acute changes was devised. Among the 279 smokers, those exposed to the Prebake process and with high exposure to the Soderberg had a higher index on average than those with low exposure to the Soderberg process and unexposed workers. Among the 106 workers who had never smoked, no significant differences appeared.
