Abstract
In response to a request from the Executive Director of the Colorado River Tribal Council Tribal Health Department, an evaluation was conducted of possible hazardous conditions on the reservation in Parker, Arizona resulting from pesticide exposure during cotton harvesting (SIC-0131). Pesticide exposure to mechanical cotton picker operators, cotton cart workers and cotton gin workers were evaluated. Personal and area air samples were collected along with wipe samples from the skin and work surfaces as well as bulk samples. DEF (78488), Lorsban (2921882), Pydrin (51630581), Nudrin (16752775) and Aldicarb (116063) were each found in the bulk samples. Mean red blood cell cholinesterase levels at the start of the study were 0.754+/-0.113 pH units for the controls, and 0.800+/- 0.110 pH units for the cotton workers. End of study means were 0.654+/-0.088 pH units for controls and 0.628+/-0.083 units for the cotton workers, indicating a mean drop of 11.7%+/-11.3 for the controls and of 18.2%+/-14.9 for the cotton workers. In all, 36% of the controls and 63% of the cotton workers experienced a drop in their cholinesterase levels of more than 15% which is considered the limit of normal variation. The authors conclude that a health hazard existed due to exposures to pesticide laden materials; local comparison groups also showed a similar effect. The authors recommend measures to improve worker health.
