• Description:
  Studies were made of the endotoxin concentrations in airborne cotton dusts in carding rooms as it relates to acute human pulmonary function changes. Three varieties of cotton were grown for the study, Deltapine 61 (DPL61), Acala SJ-5 (SJ5), and GSA-71. These were produced at three geographical locations: California (CA) San Joaquin Valley, the High Plains of West Texas (TX), and the Mississippi (MS) Delta. The greatest endotoxin contamination was noted both in 1982 and 1983 in MS produced varieties. The least contamination in 1982 was found in TX grown varieties and CA varieties had the lowest contamination levels in 1983. The findings demonstrated that the geographical area in which the crop was raised had a large part to play in the endotoxin contamination of the carded dust. This was true regardless of which variety was being examined. The particular variety of crop had more effect on 1982 than it did on 1983 data. The SJ5 variety contained the highest levels of endotoxins in all geographic areas. Dusts from DPL61 contained the lowest amount of endotoxin contamination in CA and TX produced crops. A good correlation was obtained between acute pulmonary function changes and elutriated endotoxin contents in the airborne cotton dusts. The correlation between endotoxin level and pulmonary function response exceeded that between gravimetric dust level and pulmonary function response. The authors concluded that gravimetric measuring alone may not provide adequate monitoring of health and safety conditions at textile mills. [Description provided by NIOSH]
