      <subfield code="a">The major objective of this study was to determine the minimal duration of exposure to 1.0 ppm S=2 sufficient to elicit bronchoconstriction significatly greater than that observed with exposure to clean air (CA). A secondary objective was to describe the postexposure temporal pattern of SO2-induceed bronchoconstriction</subfield>
