The estimated exposure thresholds for RBC acetylcholinesterase (AChE) inhibition and plasma butyrylcholinesterase (BuChE) inhibition were listed incorrectly in the Results as "99% available RBC AChE, and 90% available plasma BuChE." The correct values are 99.98% for available RBC AChE and 96.25% for available plasma BuChE.

In addition, the RBC AChE level associated with a 15% cognitive deficit, based on data from Farahat et al. (2003), was derived incorrectly as [BM.sub.RBC-AChE], = (100 - 80)/100 = 0.20. The correct value is [BM.sub.RBC-AChE] = (100 - 80)/80 = 0.25. The estimate shown in the original Figure 5 for the level of [BM.sub.AChE] associated with a 15% cognitive deficit in Farahat et al. (2003) also was incorrect. The corrected figure is included in this erratum.

The authors confirm that these changes do not affect the study conclusions. The authors regret these errors.
