Second study links PAH exposure to reduced IQ of children Armidale's Air Quality Policy - Summary of Submissions More Air Pollution News Particulate pollution affects heart health, experts speak about woodsmoke and health Washington State Dept of Ecology video Recommendations of Health Experts The Australian Lung Foundation (ALF) recommends: “use alternative methods (instead of wood heaters) for climate control, including insulating and improving the energy efficiency of homes, flued gas and and electric heaters and energy efficient house design” http://www.lungfoundation.com.au/content/view/99/104/ The American Lung Association "strongly recommends using cleaner, less toxic sources of heat. Converting a wood-burning fireplace or stove to use either natural gas or propane will eliminate exposure to the dangerous toxins wood burning generates including dioxin, arsenic and formaldehyde” see http://www.lungusa.org/press-room/press-releases/cleaner-alternatives-for-winter-heat.html The Australian Medical Association called on the Tasmanian Government to ban woodheaters in the Tamar Valley (Launceston) and introduce new subsidies for alternatives http://www.abc.net.au/news/stories/2006/10/16/1765526.htmArmidale Lung Specialist Dr Gary Baker, “We need to eliminate or minimise the need for heating by design. Wherever possible, substitution with other non-polluting technologies is the best." Truth vs Sensationalism
The wood heating industry argues that providing people
with simple facts, e.g. that the average new woodheater produces as
much health-hazardous PM2.5 pollution as 100-267 passenger cars is
"sensationalism". Simple facts needed to make an intelligent decision about home heating systems should never be considered "sensational". Much more sensational is the problem that these facts are not widely known, and that industry has been allowed to describe a product that emits more health-hazardous PM2.5 pollution than 100 passenger cars as clean or environmentally friendly. Intelligent people generally take claims of cigarette manufacturers (who make money from selling their product) with a pinch of salt. For similar reasons, the recommendations of health experts such as the Australian Lung Foundation, the American Lung Association and the AMA should be considered more reliable than what the wood heating industry wants us to believe. American Lung Association - 10 tips for cleaner air 7. Avoid burning wood. Avoid use of wood burning in indoor and outdoor fireplaces. Just like tobacco smoke, wood smoke pollution is harmful to your health. Wood burning comprises 33 percent of particle pollution during the winter in some areas. Cleaner burning alternatives such as natural gas and electric fireplaces are available for the glow without the smoke! | Welcome to the Australian Air Quality Group Website
These pages summarise (and provide sources for) important information about the health hazards of one of the major sources of health-hazardous PM2.5 fine particle pollution - wood heating.
Another section (under costruction) will provide more comprehensive research information into all sources of air pollution and non-polluting environmentally alternatives such as solar heating.
Basic information:
Air pollution
* Wood heating doesn't emit less greenhouse gases than other forms of heating
* Local doctor so concerned about Armidale's woodsmoke that he is urging people with respiratory problems to get out of town Health
* PAH (polycyclic aromatic hydrocarbon) exposure causes genetic damage in babies and a 5 point reduction in a child's IQ at age 5. These effects were found in a US study of mothers exposed during the 3rd trimester of pregnancy to PAH levels just over a quarter of Armidale's average winter measurements.
* Exposure to PM2.5 in childhood is associated with increased risk of chronic obstructive pulmonary disease in adulthood
* 8.8 additional visits to Armidale GPs every day in winter for woodsmoke-related respiratory complaints Greenhouse Gas Emissions
With abrupt climate change approaching faster than predicted according
to scientists, fast-action mitigation strategies are essential in order
to avoid passing the tipping points. The Institute for Governance & Sustainable Development (IGSD) has embarked
on a “fast-action” climate mitigation campaign to promote non-CO2
strategies that will result in significant emissions reductions in the
near-term. These strategies include reducing emissions of short-term climate forcers, such as black carbon, methane, and tropospheric ozone. Under normal operation, methane emissions from the average Australian wood heater in Sydney, Perth and Brisbane will cause more global warming over a 100-year timespan than heating the same house with gas or a reverse cycle airconditioner. The problem, as explained by the IGSD, is that the world's climate might reach a tipping point in substantially less than 100 years. Over a 50 year timespan, the average Australian wood heater will cause more global warming than gas or reverse cycle electric heating, even if the wood is from a sustainable source. Environmental Sustainabilty - Logs Have Life Inside The Federal Department of Environment Brochure explains:"What people often don't know, is that collecting logs for firewood can harm animals, birds and other creatures living and feeding inside. Hollow logs provide a safe and warm place for animals to hide in and raise families. Birds make nests in hollow trees. Insects, like the stag beetle, feed on dead wood to survive. Many birds, reptiles and mammals in turn need to eat insects for their survival. Sadly, not enough people know that logs have life inside, meaning many types of animals and plants are disappearing when their homes are burnt for firewood." Collecting dead wood for firewood affects many different types of creatures: birds, mammals, reptiles,amphibians, invertebrates and fungi.
