How wood burners are used is a major contributor to winter air pollution in urban areas, new research is finding.
Wood burners are a major source of heating in New Zealand and particularly in Otago.
National Institute of Water and Atmospheric Research (Niwa) air quality scientist project leader Jeff Bluett said(…) wood burners in particular houses are `gross emitters’.”
Those houses were producing “grossly disproportionate” amounts of particulates which could harm people’s health.
“What we want to do is identify the reasons why those gross emitting events occur.”
Otago’s air plan rules were modernising burners in Central Otago now, and in other airzone towns in the region over a period of time. The rules in Central Otago would effectively mean the end of coal smoke and rubbish burning, he said.
However, the only guaranteed way of keeping the smoke down was automated systems,
