Related to perchloromethane: perchloroethylene
a clear, colorless, mobile liquid used as a solvent. The most common route of poisoning is by inhalation of its vapors; it can also be absorbed through the skin. Toxicity results from depression of central nervous system activity and degeneration of the liver and kidneys. Signs of acute poisoning include nausea, vomiting, diarrhea, headache, and in severe cases anuria that can be fatal. Since the toxic concentrations are below the odor threshold, carbon tetrachloride should always be used in a well-ventilated area.
