Carbon monoxide (CO), restricts the transfer of oxygen to tissues and can be fatal in very high concentrations. It therefore makes sense for national governments and cities in developing countries to prioritize and invest in the establishment, operation and maintenance of ground-level air quality monitoring networks, to generate reliable data on air quality. Major urban sources include vehicles, burning of gas, coal and charcoal, wood for cooking and heating, and industrial sources still located in cities.
