In Sydney, air quality has met the national daily standard for PM2.5 particles on all but eight days in 2016. Levels rose above the PM10 daily standard on seven days. This is an increase of four and five days respectively compared to 2015.
This increase can be largely attributed to widespread hazard reduction burning during May undertaken to reduce the bushfire risk in NSW.
This air quality statement for 2016 is based on data collected by the Office of Environment and Heritage at its monitoring networks across the state and includes a particular focus on air quality in the Hunter Valley.
