UPDATE: Smoke haze from burnoffs pushed Tasmania close to breaching air safety standards last week.
In one 24-hour period, emission levels from the forestry regeneration and fuel-reduction burns “were approaching the standard”, state environmental management director Warren Jones told the Sunday Tasmanian.
Elevated particle levels had been detected in Launceston and Hobart on several days during the week.
A Sunday Tasmanian investigation into the smoke haze has revealed:
Between 5000ha and 7000ha is earmarked for forestry regeneration burns this season. About 70,000ha of the state’s forest was razed by wildfire in the past summer.
The smoke contains a mix of carbon monoxide, tar, ash, ammonia and known carcinogens such as formaldehyde and benzene.
