vomiting agents

vomiting agents,

chemicals that induce nausea and vomiting. Vomiting agents include adamsite, diphenylchlorarsine, and diphenylcyanoarsine. They are used as aerosols, and exposure is primarily by inhalation but also by ingestion and by skin and eye contact. They initially act like tear gas, and their effects progress to difficulty in breathing, nausea, and vomiting. Effects are self-limited, generally disappearing within 2 hours. Death may occur with exposure to high concentrations in confined spaces.
