Niwa air quality scientist Jeff Bluett says during winter dom- estic wood burners are the largest source of hazardous pollution in our air, but operating them prop- erly can reduce the problem sig- nificantly. In New Zealand, wood burners are without a doubt the biggest cause of particulate pollution in our urban environment, and in a lot of places they produce amounts that risk exceeding air pollution standards. The Kapiti Coast has an advantage because you don't have a huge population and it's rela- tively windy, but you don't need a whole lot of burners before you get a problem.'' However, results from a Greater Wellington Regional Council study in Raumati South earlier this year suggest domestic fires may be pushing air pollution over national standards. Previously air quality was not monitored in the district because coastal weather conditions nor- mally mean a reduced risk. Particulates produced by wood burners have a health effect even at very small levels, Mr Bluett says, and are especially harmful for the young, elderly, and those who are already sick. On a very local scale they are putting out particulate or hazard- ous materials that people breathe in and can be harmful and people don't realise that they are harm- ful.'' Mr Bluett is leading a Niwa investigation into how much emissions are produced by dom- estic wood burners and how emissions can be minimised by regions and households. The results will be provided to regional councils to help them for- mulate regulations and guidelines for wood burners in homes. We are finding that when we look at the distribution of emissions, wood burners in par- ticular houses are gross emitters,'' Mr Bluett says. If we manage to fix the top 10 or 20 per cent of houses, we'll more than halve the amount of pollution.'' Different types of wood burners are more appropriate for heating different spaces, and burning dif- ferent types of wood, so home owners should learn how to use their own wood burner respon- sibly, he says. They should choose an appro- priate size for the room they are heating . . . and operate it accord- ing to the instructions and use good quality fuel.'' While some wood burners burn soft woods like pine effectively, others are more suited to hardwoods like blue gum. Mr Bluett says wood should also be seasoned or dried out for use next season, otherwise much of the energy produced will be used evaporating moisture from the wood, requiring more fuel.
