    Hydrogen sulfide, which is a kind of nerve agents, can easily cause poisoning and also has strong stimulation to mucous membrane. High concentrations of hydrogen sulfide can restrain respiratory center directly and then causes death by suffocation. Table 2 shows it’s harm to people in different concentrations of hydrogen sulfide.
