High dust levels recorded in the Hunter

 A series of higher than average fine particulate matter readings in Muswellbrook have again raised concerns about air quality in the region.

The air quality monitor recorded daily levels of between 61.2 and 118.2 micrograms per metre on five separate occasions between 20 and 30 August, according to the Newcastle Herald.

However the daily average remained at PM2.5, although poor quality air alerts were issued on 27 and 28 August.

“The high readings occurred overnight during cool and calm conditions which is conducive to particulate build-up and characteristic of the type of particle matter expected from fuel combustion, including woodsmoke,” a spokeperson for the Office of Environment and Heritage said.

An upper Hunter coal miner, Gloucester Coal, was recently accused of obscuring dust monitors that measure air quality near its operations.
