The acute clinical effects of inhaling flax dust were evaluated, as produced during the processing of flax fibers under conditions similar to those in colonial America. Exposure to the dust for about five hours caused minor symptoms of chest tightness in five healthy persons, accompanied by decreases of maximum expiratory flow rates. The decreases in expiratory flow rates indicated acute small airway obstruction. Measurements of flow rates on partial expiratory flow volume (PEFV) curves were more sensitive than flow rates on maximum expiratory flow volume (MEFV) curves and forced expiratory volume in 1 second (FEV-1) in assessing constrictor effects of flax dust. However, flow rates on flow volume curves were more variable than under control conditions in rates for forced expiratory volume in 1 second. Acute symptoms of byssinosis may have been present among early settlers in America who processed flax in their barns. Since the barns were used for many other purposes as well, children and other farm workers were probably at risk.
