Carbon Monoxide (CO)
Carbon monoxide is a toxic, colorless, odorless and tasteless gas. It is the by-product of incomplete combustion of carbon-containing materials in an oxygen-deficient environment. One of the main sources in the indoor environment is the occupants' smoking activities. High indoor levels of carbon monoxide can also result from the entry of outdoor vehicle exhaust fumes into a building's ventilation system.
Typical indoor concentrations, in the absence of any sources of machine exhaust, are usually lower than that found outside. The toxic properties of carbon monoxide are associated with its high affinity for oxygen-carrying proteins such as haemoglobin and myoglobin. Hence, a high indoor concentration of carbon monoxide may impact important organs with a high oxygen demand, such as brain and heart.
Singapore National Environment Agency recommends that the maximum threshold level for carbon monoxide should not exceed 9ppm, based on "Guidelines for Good Indoor Air Quality in Office Premises".
