Vehicle exhaust, particularly from gasoline-powered engines, is the major contributor to CO emissions in urban environments.

Eye irritation is not a common symptom of CO exposure. The primary health effects of CO include headaches, dizziness, and cardiovascular issues.

Carbon monoxide has the chemical formula CO, consisting of one carbon atom and one oxygen atom.

High traffic volume, cold weather, and calm wind conditions can all contribute to elevated CO levels in the air.

CO binds to hemoglobin in red blood cells, forming carboxyhemoglobin, which reduces the blood's ability to carry oxygen to tissues.

Children, elderly individuals, and those with heart or lung conditions are more susceptible to the adverse health effects of CO exposure.

The U.S. Environmental Protection Agency (EPA) recommends an indoor air quality standard of 9 ppm for CO as an 8-hour average.

Increasing the number of vehicles on the road would lead to higher CO emissions, not a reduction.

Hemoglobin's primary function is to bind to oxygen in the lungs and transport it to tissues throughout the body.

Nausea, vomiting, and confusion are all common symptoms of CO poisoning.

Carboxyhemoglobination is the term used to describe the process by which CO binds to hemoglobin, forming carboxyhemoglobin.

Long-term exposure to low levels of CO is associated with increased risk of heart disease, developmental problems in children, and reduced cognitive function, but not improved lung function.

Agricultural activities, such as the burning of crop residues and the use of certain fertilizers, can be significant sources of CO emissions in rural areas.

CO exposure during pregnancy has been linked to increased risk of miscarriage, low birth weight, and neural tube defects, but not improved fetal development.

If you suspect CO poisoning, it is important to take immediate action by opening windows and doors, turning off all gas appliances, and evacuating the premises.
