RESUMO
This work is concerned with the problem of the chronic toxicity of sulphur dioxide in pulp mills. Fifty-four workers at four different pulp mills working in the acid towers and digester plants have been investigated with special regard to symptoms and signs of respiratory disease. Vital capacity has been measured with a `Kifa' apparatus and maximal expiratory flow with a Wright peak flow meter. The concentration of sulphur dioxide in the working atmosphere has been measured during general working conditions on a single day, and the values were found to range between 2 and 36 parts per million.
