There is no documentation indicating that a minimum number of pollutant sub-indexes are required before selecting a highest value for the composite air quality standard value. Additionally, no guidance is provided for data coverage for averaging periods over one hour, such as 4 hour and 8 hour used for CO and Ozone in some states.

In the recorded breakpoint concentrations for all regions except Queensland and Tasmania, there was overlap between the lower and upper limits of subsequent risk categories. To mitigate this, all pollutants were assumed to be rounded according to the apparent convention as reported by their respective government organizations. Reported pollutant concentration data, either in tables or in map format, was analyzed to determine how many significant figures each pollutant was reported with. The number of significant figures reported for each pollutant was assumed to be the same number of significant figures values were rounded to when establishing the upper limits of the breakpoint concentration table. We have assumed that the upper limit values are not inclusive. This is inferred as the first column in the provided breakpoint concentration tables include the non inclusive less than symbol.

In the recorded breakpoint concentrations for all regions except Queensland and Tasmania, there was overlap between the lower and upper limits of subsequent risk categories. To mitigate this, all pollutants were assumed to hold one significant figure for the upper limit based on reported data. We have assumed that the upper limit is not inclusive and is rounded/truncated to the first decimal place. This is inferred as the first column in the provided breakpoint table includes the non inclusive less than symbol.

An exception to this convention is South Australia. In both South Australia and Queensland, breakpoints for O<sub>3</sub>, SO<sub>2</sub>, and NO<sub>2</sub> were converted from ppb to ppm for consistency with the other regions. For South Australia where there was overlap in breakpoint limits, PM<sub>2.5</sub>, PM<sub>10</sub>, and CO were held to one significant figure while O<sub>3</sub>, SO<sub>2</sub>, and NO<sub>2</sub> were rounded to the nearest integer to reflect that of Queensland.
