Monitoring agrichemical use
In addition to completion of the agrichemical use survey of 13 questions, self-reported chemical use is recorded during each visit. Participants are provided with counseling regarding their EAChE levels in accordance with AgriSafe guidelines (Fig. 2). The USA’s Department of Pesticide Regulation specifies that a drop to 70 % or lower in red blood cell AChE or to 60 % or lower in
plasma cholinesterase relative to the individual’s baseline is an indication for immediate removal of the individual from all exposure to organophosphate and carbamate pesticides [25]. Participants will be provided with a summary of their EAChE baseline and subsequent results at
the conclusion of the study. This methodology reflects recent exposures and is used to provide feedback at the time of testing. However, it is noted that the level of current exposure is not a measure of long-term exposure
