Wood Smoke Update

There are an estimated 14,000 wood heaters in the Tamar Valley, in which Launceston is situated. The particle pollution levels (called PM10) were very high up to 1991. Maximum levels of PM10 were up to 240 units (micrograms per cubic metre) in 1991, compared with the current recommended “safe” maximum of 50 units (National Environment Protection Measure). Up to about 1997 we had about 50 days per year when the daily PM10 values were above 50 units. Since 2000, the levels have fallen to a maximum of 100 units per day and the number of “high” days has fallen below 30. The target is to reduce the number of “high” days to 5 or less per year. The Tasmanian Government has undertaken to achieve this by 2008.

The factors which have helped so far include:
