Study Notes
Properties
- Carbon monoxide (CO) is a colorless, odorless, tasteless, and highly toxic gas
- Molecular formula: CO
- Molecular weight: 28.01 g/mol
- Density: 1.145 kg/m³ at 20°C and 1 atm
- Boiling point: -191.5°C
- Melting point: -205.5°C
Sources of Exposure
- Incomplete combustion of fossil fuels (e.g., car engines, generators, furnaces)
- Wood-burning stoves and fireplaces
- Tobacco smoke
- Industrial processes (e.g., metal processing, chemical manufacturing)
- Natural sources (e.g., volcanic activity, wildfires)
Health Effects
- Binds to hemoglobin in red blood cells, reducing oxygen delivery to tissues
- Can cause headaches, dizziness, nausea, and fatigue at low concentrations
- Higher concentrations can lead to:
- Confusion and disorientation
- Seizures and loss of consciousness
- Respiratory failure and death
Symptoms of CO Poisoning
- Mild exposure:
- Headaches
- Dizziness
- Nausea and vomiting
- Moderate exposure:
- Confusion and disorientation
- Chest pain
- Shortness of breath
- Severe exposure:
- Seizures
- Loss of consciousness
- Respiratory failure
Prevention and Treatment
- Install CO detectors in homes and buildings
- Ensure proper ventilation and maintenance of fuel-burning appliances
- Avoid idling cars in enclosed spaces
- Treat CO poisoning with oxygen therapy and supportive care
- Consider hyperbaric oxygen therapy in severe cases

Sources of Exposure to Carbon Monoxide
- Incomplete combustion of fossil fuels, such as car engines, generators, and furnaces, can release carbon monoxide
- Wood-burning stoves and fireplaces are also a source of exposure
- Tobacco smoke and industrial processes, like metal processing and chemical manufacturing, can release carbon monoxide
- Natural sources, including volcanic activity and wildfires, can also release carbon monoxide
Health Effects of Carbon Monoxide
- Carbon monoxide binds to hemoglobin in red blood cells, reducing oxygen delivery to tissues
- At low concentrations, it can cause headaches, dizziness, nausea, and fatigue
- Higher concentrations can lead to confusion, disorientation, seizures, loss of consciousness, and respiratory failure, which can be fatal

- Severe exposure symptoms include seizures, loss of consciousness, and respiratory failure
Prevention and Treatment of Carbon Monoxide Poisoning
- Installing CO detectors in homes and buildings can help prevent poisoning
- Proper ventilation and maintenance of fuel-burning appliances can reduce the risk of exposure
- Avoiding idling cars in enclosed spaces can also prevent poisoning
- Treatment for carbon monoxide poisoning includes oxygen therapy and supportive care, with hyperbaric oxygen therapy considered for severe cases
