Those stinky old slow-combustion wood stoves, still quite common in Tasmania, are as dangerous as they seem. But I wonder what accounts for the sex difference reported here. AFP takes up the story:
REDUCING the use of wood-burning stoves in Launceston led to a sharp fall in deaths from respiratory diseases and heart failure, a study published today says.
The paper, published by the British Medical Journal, highlights the pollution risks from inefficient biomass burning, used by billions of people for heating and cooking.
University of Tasmania researchers looked at what happened when the city implemented a scheme to reduce pollution from wood smoke.
It launched a campaign to educate residents about the risks of smoke from wood-burning stoves and offered help to replace these with electric ones.
From 2001 to 2004, the number of households that used wood-burning stoves fell from 66 to 30 per cent. Atmospheric pollution from air particulates during winter fell by 40 per cent.
Deaths among men fell by 11.4 per cent, particularly from cardiovascular causes, which saw a decline of 17.9 per cent, and from respiratory causes, which retreated by 22.8 per cent.
…There was no statistically significant fall among women, a question that was not addressed by the study. “It does tell us that improving the air quality improves death rates,’‘ said Fay Johnston, a GP and environmental epidemiologist at Menzies Research Institute Tasmania who led the study..“Death through air pollution is the tip of the iceberg.’‘
The mortality figures derive from a 6 1/2 year comparison between Launceston with Hobart, the capital city, which did not have any air-quality interventions.
