Acetylcholinesterase inhibition dose-response modeling for chlorpyrifos and chlorpyrifos-oxon

► Provides a benchmark dose analysis for a novel acetylcholinesterase study. ► Provides toxicity values that can be used for chlorpyrifos. ► Provides a meta-analysis of previous acetylcholinesterase inhibition measurements. ► Discusses use of RBC and brain acetylcholinesterase for risk assessment.
