A SERIES of increases in fine particulate matter pollution readings at Muswellbrook has reignited concerns about Upper Hunter air quality.
The Muswellbrook monitor, which measures levels of particular matter less than 2.5microns in diameter, forms part of the Upper Hunter air quality monitoring network.
The monitor recorded daily levels between 61.2 and 118.2micrograms per cubic metre on five occasions between August 20 and August 30.
Although daily PM2.5 averages for the period fell within ‘‘very good’’ to ‘‘poor’’ National Environment Protection standards, poor air quality alerts were issued on August 27 and28.
