Carbon monoxide (CO) poses significant risks to human health, primarily through its ability to bind to hemoglobin in the bloodstream. Unlike oxygen, CO attaches to hemoglobin more readily, thus reducing its capacity to transport oxygen throughout the body. This can lead to symptoms such as headaches, dizziness, and in severe cases, loss of consciousness or even death. Prolonged exposure can also lead to long-term effects on neurological function. Awareness and monitoring of CO levels, especially in enclosed spaces, are crucial measures to safeguard public health.
