New Mechanism To Explain Carbon Monoxide Poisoning Identified
...d everyday. The physiologicalconsequences of these sustained
levels of CO exposure are virtually unknown. The classic explanation for CO's poisonous action is that it binds tohemoglobin molecules in the blood, impairing oxygen delivery to the body'scells. Eventually cells essentially suffocate and die....
