| Comments |
The use of nicotine as an insecticide was popular in the 1920s and 1930s when cases of occupational poisoning were reported. Lethal effects are due to a curare-like respiratory arrest. [ACGIH] Symptoms of mild poisoning are nausea and vomiting. The cholinergic syndrome (diarrhea, increased salivation and respiratory secretions, and bradycardia) is seen in more severe poisoning. Seizures and respiratory depression are rare complications of severe poisoning. Green tobacco sickness due to skin absorption of nicotine has been described in workers who handle tobacco. [Ford, p. 985] |

Human data: The fatal human dose has been estimated to be about 50 to 60 mg [Lazutka et al. 1969]. [Note: An oral dose of 50 to 60 mg/kg is equivalent to a 70�kg worker being exposed to about 30 to 40 mg/m3 for 30 minutes, assuming a breathing rate of 50 liters per minute and 100% absorption. |
