Air toxics are pollutants that can be present in the atmosphere in low concentrations and are known or suspected to cause serious health or environmental problems. Information about the sources and health effects of air toxics is available at the Department of the Environment and Energy web site. There are five compounds used as indicators of toxic air pollutants in Australia: benzene, toluene, formaldehyde, xylenes and benzo(a)pyrene (as an indicator for PAH). These compounds are included in the Tasmanian Air Toxics Monitoring Program which commenced in 2008.
A general description of air toxics is available on the
Air Quality Education Resources web page.
Air Toxics Monitoring in Tasmania
Tasmania has implemented a state-wide air quality monitoring program which expands the information base to assist in evaluating the State's air quality and monitoring trends. The program includes upgrading the present monitoring program to meet the requirements of the
Air Toxics NEPM.
The monitoring program for air toxics is a primary objective of the
Tasmanian Air Quality Strategy. A detailed program has been planned that identifies 16 locations for air toxics monitoring. Monitoring at five of these sites commenced in 2008 and 2009 for screening purposes and to assess requirements for on-going monitoring. The program expanded in 2010 with air toxics monitoring at six locations: Ti Tree Bend, South Launceston, Glenorchy, Warrane, Hobart (Cleary's Gates), New Norfolk and Rowella (2008/09 only).
Preliminary results indicate seasonal variations with higher levels in winter coinciding with increased usage of domestic wood heaters. Results indicate that the NEPM Monitoring Investigation Levels are unlikely to be exceeded at the sites monitored.
