Carbon monoxide concentrations
Carbon monoxide levels have continued to decline over the past decade with levels in the last six years less than 20% of the National Environmental Protection Measure (NEPM) Air Quality Standard.
Carbon monoxide is formed through incomplete combustion of fuels containing carbon.
In urban areas, motor vehicles are the largest producer of carbon monoxide. Despite more vehicles on the road, emission controls such as catalytic converters have helped significantly reduce carbon monoxide emissions, and corresponding levels in the air, in recent years.
Monitoring is carried out at two locations adjacent to major roads in South East Queensland and at one location next to industry in Gladstone. Levels have continued to decline over the past decade with current levels less than 20% of the National Environmental Protection Measures (NEPM) Air Quality Standard.
