The organophosphorus compounds reduce the activity of cholinesterase in blood, and cause dysfunction of nervous system. Among organosulfur compounds, low concentrations of mercaptans can cause discomfort and high concentrations can cause death. In oxygen-containing organic compounds, inhalation of high concentrations of ethylene oxide can lead to death; acrolein has strong irritation to mucous membranes; pentanol can cause headache, vomiting, diarrhea, etc.
