Air quality bulletin: South East Queensland

Air quality summary tablesTables 3 to 15 present summaries of air quality data for each month of the preceding 12 months. These tables show the month-to-month variation in air quality. A monthly entry is given when at least three-fifths of the maximum possible number of observations during the month are available. When data is not available for the entire month this is indicated by the abbreviation ‘n.d.’ (no data). A dash is inserted when less than three-fifths of the data are available. Where data is not recorded, the reason for the low data availability is summarised in Table 16 at the end of this bulletin.

Air quality summary graphsFigures 1 to 31 summarise available air quality data for each day of June. Only the maximum recorded level for each day is used to show the day-to-day variation in air quality. Figures 30 and 31 show the averaged daily dust deposition rate for June.

Air quality monitoring was carried out by the Queensland Government at 14 sites in South East Queensland during June 2020. Data from Caltex Refineries (Qld) Ltd’s monitoring sites at Wynnum North, Wynnum West and Lytton along with the Department of Transport and Main Roads’ South Brisbane monitoring site are also included.

Air pollutants monitored include carbon monoxide, ozone, nitrogen oxides, sulfur dioxide, benzene, toluene, xylenes, formaldehyde, visibility-reducing particles, PM10

(particles less than 10µm in diameter) and PM2.5

(particles less than 2.5µm in diameter). Dustfall (dust particles that rapidly settle from the air due to their large size) and total suspended particulate (TSP) matter that can cause nuisance was also monitored.

IntroductionAir quality monitoring gathers information on the quality of the air environment. The objectives of the monitoring are to check compliance with ambient air quality guidelines, identify long-term trends in air quality, investigate local air quality concerns and assess the effectiveness of air quality management strategies.

Table 1. Air pollutants monitored at South East Queensland sites.

Reporting protocolData presented in this bulletin are based on clock hours. Hourly or other averages are constrained to start and finish on a clock hour.

GuidelinesAir quality measurements are compared against air quality objectives contained in the Queensland Environmental Protection (Air) Policy 2019 (EPP (Air)) to assess whether pollutants levels could affect health and wellbeing. The EPP (Air) visibility objective is used to assess the impact of visibility-reducing particles on visual air quality. Limit values for TSP and dustfall specified in the former Department of Environment and Heritage Protection (DEHP), now the Department of Environment and Science (DES), guideline document Application requirements for activities with impacts to air (Air Impacts Guideline) are used to assess dust nuisance effects. The relevant guidelines are shown in the air quality summary table for each pollutant.

The EPP (Air) PM10 24-hour objective was exceeded at the Lytton monitoring site on 15 June. The elevated PM10

concentrations occurred during south to south-westerly winds. Lower PM10 concentrations at the nearby Wynnum North and Wynnum West monitoring sites indicated that the elevated dust levels were restricted to the industrial area where the Lytton monitoring site is located, and were likely to have been the result of localised dust-generating activities.

The EPP (Air) PM2.5 annual average objective was exceeded at the Lytton, Cannon Hill, South Brisbane, Woolloongabba, Rocklea and Southport sites over the 12-month period ending June 2020. Local PM2.5 emission sources such as motor vehicle emissions, together with additonal PM2.5 emissions from major regional bushfire smoke events in November and December 2019, led to these exceedances.

Visibility at the Mountain Creek monitoring site fell below the EPP (Air) objective of 20km for a one hour period on 6 June during a south-westerly winds. While a specific source of the particles could not be identified, smoke from a local source was most likely responsible.

The DES nuisance dust deposition limit of 120 mg/m2/day, averaged over one month, was exceeded at both Toowoomba dustfall sites during the month of June, when the predominant wind direction was south to south-easterly. Particle composition analysis indicated that both samples contained very little to no coal dust, indicating that coal trains did not contribute to the exceedances. Furthermore, a greater dust deposition rate was measured at the Brooks Street site (to the east of the rail corridor) compared to the Mort Street site, suggesting a local dust source located east to south-east of the rail corridor was likely responsible. 30-day

Compliance with air quality guidelinesDuring June, measured pollutant levels, with the exception of PM10, PM2.5, visibility-reducing particles and dustfall, did not exceed the relevant EPP (Air) air quality objectives, or DES dust nuisance limit values at Queensland Government and industry air monitoring sites in South East Queensland.

The Department of Environment and Science (previously the Department of Environment and Heritage Protection) Air Impacts Guideline recommends that short-term (24-hour) TSP concentrations be compared against the trigger levels provided in the New Zealand Ministry for the Environment's Good practice guide for assessing and managing the environmental effects of dust emissions 2016 to assess dust nuisance impacts.

The New Zealand dust nuisance trigger level for high sensitivity areas is a 24-hour average of 60 µg/m3.

‡Due to Cross River Rail Project works being conducted at Fairfield station, the dust deposition sampling equipment previously located at Fairfield was relocated to a site on the rail corridor at Sherwood in January 2020.

Table 15. Monthly average dust (insoluble solids fraction) deposition rate (mg/m2/day), July 2019 to June 2020.

The Department of Environment and Science (previously the Department of Environment and Heritage Protection) Air Impacts Guideline

recommends a dust deposition limit of 120 mg/m2/day, averaged over one month, be used to assess dust nuisance.

There is a minimum dust deposition rate that can be determined with the sampling equipment and laboratory method used. Dust deposition rates below this minimum reporting value are preceded by a "<" sign in this table.

n.d. indicates no data are available.

†At the Cannon Hill site dustfall monitoring is carried out on both sides of the rail corridor.
