Abstract
Under controlled conditions in an environmental chamber 16 healthy young volunteers were exposed to combinations of SO2 (2.6 or 13 mg/m3) and inert plastic dust (2 or 10 mg/m3) or of SO2 (13 mg/m3) and dust (10 mg/m3) coated with V. During periods in clean air and during exposures of 5-h duration, nasal mucus flow rate, nasal airflow resistance, forced vital capacity and subjective discomfort were measured. Reductions in nasal mucus flow rate, forced expiratory flow (FEF25-75%) and discomfort were related principally to SO2 concentration. The combined effects of SO2 and dust were, at the most, additive and there was no indication of potentiation effects. No effect could be attributed to the coating of dust with V.This publication has 0 references indexed in Scilit:
