- Ozone concentrations
While ozone levels in Townsville and Gladstone have never exceeded air quality standards, South East Queensland experienced exceedances in 2011 and 2015.
- Visibility-reducing particles
While the past decade has seen a downward trend in the number of days with reduced visibility throughout Queensland, significantly more days were affected in 2009 and 2011, and in Gladstone in 2015 and 2017, due to bushfires.
- Particulate concentrations
Particle concentrations have exceeded National Environmental Protection Measures (NEPM) Air Quality Standards since monitoring began in 1986. While exceedances of the PM10 24-hour standard show no clear trends, annual average PM10 concentrations in most regions are trending down. Exceedances of the PM2.5 24-hour standard and annual averages are both trending down.
- 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.
- Lead concentrations
Routine monitoring of lead in air is no longer undertaken in South East Queensland due to the low ambient concentrations following removal of lead in petrol. Lead monitoring results from Mount Isa and Townsville show that lead levels are below the National Environmental Protection Measures (NEPM) Air Quality Standard.
- Nitrogen dioxide concentrations
Since 1993, there have been no exceedances of the National Environmental Protection Measures (NEPM) Air Quality Standards and no clear trends over the past decade. Levels of nitrogen dioxide in all regions are consistently well below the standards.
- Sulphur dioxide concentrations
Sulphur dioxide levels in all regions except for Mount Isa have met the National Environmental Protection Measures (NEPM) Air Quality Standards. Occasional 1-hour and 24-hour NEPM standard exceedances in Mount Isa are due to smelting operations.
- Vehicle kilometres travelled
Total motor vehicle travel (cars, trucks, buses), expressed as total vehicle kilometres travelled, shows continued and sustained growth over time.
- Number of registered vehicles
The total number of registered motor vehicles shows continued and sustained growth over time.
- Vehicle emissions
Emissions from motor vehicles are a function of many factors, but most importantly total travel, fleet mix and emission control technology and driving behaviour.
- Major air pollutants
The National Pollutant Inventory (NPI) tracks air pollutant emissions for industrial sources across Australia. The NPI results for industrial sources in Queensland show that several pollutants generally have trended upwards for the past five years. Increases in industrial emissions for a few key air pollutants reflect increased demand in commodities.
|National Pollutant Inventory (NPI)|
The National Pollutant Inventory (NPI) is a national program, implemented in Queensland under Chapter 6 of the Environmental Protection Regulation 2008 (The Reg). The Reg mirrors the requirements outlined in the NPI National Environmental Protection Measure (NPI NEPM), which are implemented cooperatively by the Australian and Queensland governments through a memorandum of understanding (MOU). The role of the states in the current MOU are summarised as:
The program is aimed at the acquisition of facility-based emissions and transfer data.
The Reg imposes mandatory reporting obligations on facilities triggering specific reporting thresholds. The Reg provides power to the chief executive and delegates to carry out compliance measures should facilities with mandatory reporting requirements fail to meet their obligations.
|Queensland Statewide Air Quality Monitoring Program|
The statewide ambient air monitoring program provides baseline data to assess Queensland’s air quality against relevant air quality standards or objectives, meet state and Commonwealth legislative reporting obligations, evaluate the effectiveness of management strategies to improve air quality, and inform the public of the state of Queensland’s air environment.
The statewide ambient air quality monitoring network consists of about 30 monitoring stations located in major Queensland population centres to inform Queenslanders about the quality of ambient air within their communities.
|Air Advice and Policy Support (AAPS)|
The Air Advice and Policy Support (AAPS) program provides advice to the Department of Environment and Science and other government departments, in close cooperation with the Air Monitoring unit, to support evidence-based air quality management and policy development. This work provides direct input to national programs that require a well-considered formulation of a Queensland position (e.g. National Clean Air Agreement – NCAA) and air investigations. The core activities of the program are:
|Air Quality Investigations program|
The Air Quality Investigations program supports the statutory role of the Department of Environment and Science in investigating complaints, and managing emissions for licenced facilities and compliance and regulatory enforcement activities. The investigative air monitoring program provides the baseline data required to assess the veracity of community concerns and to determine if changes are required to existing industry emissions management.
