| Abstract |
Airways' sensitivity to SO2, (PC(SO2)), was defined as the concentration of SO2 which provoked a 100% increase in specific airways' resistance (SRaw). PC(SO2) was determined for 2. asthmatics performing moderate exercise while exposed to several concentrations of SO2 up to 2.0 ppm. Substantial variability in sensitivity was observed: for 20% of the subjects, PC(SO2) was greater than 1.95 ppm SO2, while for the remaining 80%, it ranged between 0.28 and 1.38 ppm SO2. The median PC(SO2) was 0.75 ppm SO2. PC(SO2) and nonspecific airways' sensitivity to methacholine were not related. (Copyright (c) Toxicology and Industrial Health, Vol. 2, No. 3, 1986.) |
