"Who's Pluming Who?" Woodsmoke in Tasmania

 

John Innis, Senior Scientific Officer, EPA Tasmania 

Tasmania's location in the roaring forties combined with its comparatively small population, low traffic levels, and limited large-scale industry, results in low ambient levels of most of the Air NEPM criteria pollutants. However, for PM2.5 (particulate matter up to 2.5 millionths of a metre in effective diameter) Tasmania has a number of centres that exceed the 24-hour standard. The cause is woodsmoke from winter wood heating, bushfires, and planned burning operations.
 

In 2009, EPA Tasmania commenced a program of establishing a near-state-wide smoke monitoring network, using instrumentation that was both state-of-the-art and much lower cost than conventional instrumentation. This program was called "BLANkET" - the Base-Line Air Network of EPA Tasmania, and currently consists of 35 stations across Tasmania. 

The rich BLANkET dataset has provided significant insight into smoke levels and detailed information on smoke movement and dispersal across Tasmania. The data is used in improving smoke-management practices from planned-burning operations, assisting public health response during bushfires, and for real-time public information, as well as to inform EPA Tasmania for assessing air quality against national standards. The data has allowed us to assess the relative sizes of the smoke impacts from the various sources. 
 

The data indicates that most Tasmanians receive most of their particle exposure from winter woodheater smoke. Woodheater education programs are conducted each winter by both EPA Tasmania and local councils. In general however these do not appear to have significantly lowered winter smoke levels.
 

This talk will present an outline of BLANkET, overview the new understandings that have arisen from the data, and will consider some of the broader aspects of smoke pollution in Tasmania.
