No breach of national air quality standards occurred in September 2023. As in the previous year, the highest concentrations of both PM10 and PM2.5 were recorded at the city centre Queen Street site. It is also likely that ongoing construction activities in the city centre is a contributing factor.
As previously observed, the city centre sites have recorded the highest levels of NO2 concentrations. The average NO2 concentration recorded within the first eight months of this year at the Queen Street site is 58% higher than the same period of the previous year.
It is important to note that air quality at a monitoring site can vary from year to year due to weather and other influences (See Auckland air quality report, October 2021). For a brief short-term trend analysis of key pollutants concentration changes, please see Table 2.
