Carbon dioxide is a naturally occurring colourless gas, generally found outdoors in levels of approximately 390 parts per million. Therefore, carbon dioxide is not an airborne "contaminant"; rather an indicator of poor ventilation in buildings when found in elevated levels. Symptoms of exposure to elevated levels of carbon dioxide include headaches, confusion and fatigue. Symptoms will generally clear up soon after leaving the affected environment.
