Brooklyn air monitoring results for November and December 2015


Two days exceeded the PM10 air quality objective in Brooklyn during November and December.

Observations

Two days exceeded the PM10 objective during November this year, which was a similar result to October after an extended run of generally good air quality from mid-April through to early October. Pleasingly, no days exceeded the PM10 objective during December despite there being an extended period of dry and very hot conditions.

The results for 2015 show that there were fewer than half the number of days exceeding the PM10 objective in 2015 than in previous years (apart from the very wet year in 2011).

Work to seal two dusty roads in the Brooklyn Industrial Precinct was completed during 2015 and this helped drive the air quality improvements over the past eight months. Despite the promising results over this period, 11 days still exceeded the PM10 air quality objective during 2015. This is a significant improvement on the past three years when at least 28 days exceeded the PM10 objective each year, but more days still exceeded the objective in Brooklyn during 2015 than anywhere else monitored by EPA in Victoria. This shows that more actions will be required to further improve Brooklyn’s air quality during 2016.
