| Abstract |
A previous investigation of workers in pulping operations identified decrements in forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). A subset of those data (230 workers) were reanalyzed to consider accidental exposure to high levels of irritant gases, such as chlorine (CL2) or sulfur dioxide (SO2). Gassing events were more common among pulp mill workers (34%) than workers in other parts of the company (9%). Average changes of -291.9mL in FEV1 (p<0.05) and -5.00% in FEV1/FVC (p<0.05) were associated with gassing. Also, in each of the regression models for the three measures of pulmonary function (FEV1, FVC, and FEV1/FVC), there was a three-way interaction of cumulative smoking, cumulative pulp mill exposure, and gassing. The greatest decreases in FEV1 and FEV1/FVC associated with gassing were evident in the dual smoking/pulp mill exposure categories of none/high and high/none. Changes in pulmonary function persisted after cessation of exposure. |
