\nThe poisonous nature of carbon monoxide (CO) is primarily due to its ability to bind strongly to haemoglobin in red blood cells.
\n<\/section>\n
\nCarbon monoxide has a much higher affinity for haemoglobin (about 200-250 times greater) than oxygen. When inhaled, CO binds to haemoglobin forming carboxyhaemoglobin (COHb), effectively reducing the capacity of the blood to transport oxygen. This leads to oxygen deprivation in the body’s tissues and organs.
\n<\/section>\n
\nSymptoms of carbon monoxide poisoning include headache, dizziness, nausea, weakness, confusion, and in severe cases, unconsciousness, coma, and death. CO is produced by the incomplete combustion of carbon-containing materials.
