The vertical air-monitoring station located in the center of a fumigated field at a Duette, Florida, site is designed to continuously collect air samples at several heights. Fumigant-collection tubes were exchanged and air-sampling pumps calibrated every 6-12 hours for 10 consecutive days to ascertain fumigant flux rates from soil.
