Carbaryl is a neurotoxic carbamate insecticide. Greater exposures to carbaryl may lead to pin-point pupils, tearing, excessive salivation, nasal discharge, vomiting, diarrhea, muscle twitching, and coordination problems. The carbamate insecticides act similarly to the organophosphates (see Organophosphates (Toxicity)) in that they inhibit acetylcholinesterase (AChE) at nerve synapses and neuromuscular junctions.This inhibition is reversible because the inhibiting bond is much less durable; thus, the inhibition of blood AChE frequently is not evident at the laboratory. In addition, ACGIH [1971] reported that female rats may occasionally be killed by a single oral dose of 100 mg/kg [Gaines 1969]. People may also experience headaches, nausea, vomiting, stomach cramps, diarrhea, or
