Occupational dust exposures in West Texas cotton gins

Total and elutriated dust concentrations were measured by four methods for typical ginning situations. Total and elutriated levels were 0.73 and 0.47 and 0.59 and 0.26 mg/m3 per bale/hr by the gin stands and bale press, respectively. Limited data show the corresponding mass media diameters are 9.2-14.8 and 9.6-18.5 micrometer.
