Abstract
Cotton was washed in a batch system with aqueous acetone for use in human exposure studies and for chemical and microbiological analyses of lint and generated dust to determine if tannins are involved in the etiology of byssinosis. The study showed that washing high microbiological content cottons in a batch system by use of either an aqueous acetone surfactant formulation or a water surfactant formulation reduced the levels of tannins, viable total and gram negative bacteria, and endotoxins in the cotton. The washing treatments reduced the potency of the respirable dust on the ventilatory response of human subjects by about 75% but not to the level of no exposure. It was not possible to completely isolate the individual effects of tannins, viable bacteria or endotoxins on changes in human ventilatory response because the effects of the washing treatments on the residual contents of these materials were not independent.
