Abstract Criteria document for establishment of an exposure limit for sulfur dioxide. Exposure to low concentrations (>3mg SO2/m3) produces bronchoconstriction and elevated airway resistance; bronchoconstriction disappears quickly after cessation of exposure. Exposure to higher concentrations irritates the nose and throat; the irritation becomes intolerable at concentrations of 130-160mg/m3. Such concentrations produce serious lesions in the bronchial mucosa. High concentrations, such as those resulting from accidents, produce pulmonary oedema and toxic pneumonia. Exposure of monkeys and dogs to 3-13mg/m3 for 2 years gave no detectable lesions in their respiratory organs. The available data suggest that a concentration of 13mg/m3 will not accelerate the decline in spirometric parameters that occurs with age. In an annex: SO2 exposure limits in 21 countries; method of sampling and analysis.
