In response to a request from the Chairman of the Tribal Council, an evaluation was made of three cotton gins (SIC-0131) on the Colorado River Indian Reservation: the Colorado River Gin and Plantation Gin, Poston, Arizona, and Parker Valley Gin, Parker, Arizona. The potential short term and long term health effects for the approximately 10 to 18 workers at each gin site were of concern. Exposure to cotton dust, pesticide residue laden materials, nuisance dust, and noise were the primary concerns. Most of the airborne levels of cotton dust samples taken at the three gins exceeded the NIOSH recommended criteria of 200 micrograms/cubic meter. Medical evaluation showed both acute and chronic symptoms in a portion of the workers who were evaluated for exposure to cotton dust and or nuisance dust, as well as from exposure to organophosphate pesticides. Effects included eye, skin and respiratory irritation among 54% of the workers, decreases in lung function over the work day in two workers, symptoms of chronic bronchitis in six workers, and reduced pulmonary function in two workers. Statistically significant decreases were also noted in the red cell cholinesterase levels over the season, to a clinically significant degree. Significantly high noise exposures were measured for all of the jobs evaluated; only outside gin operators had exposures below 85 decibels. The authors conclude that health hazards existed at the three sites from exposures to cotton dust, pesticide residue laden materials, and noise. The authors recommend measures to improve worker health.
