Woodsmoke and Your Health
|
Although people have been burning wood since the beginning of time, we now understand that woodsmoke may contain a mix of chemicals and microscopic particles that can cause or aggravate health problems. Tiny particles may be inhaled deep into the lung tissue and cause coughing, wheezing, chest pain and shortness of breath. Woodsmoke can increase the risk of heart and lung diseases such as asthma and emphysema, and make you more susceptible to illness. Children, the elderly, and people with pre-existing lung and heart disease are especially vulnerable, but even healthy individuals can experience eye, nose and throat irritation as a result of exposure to woodsmoke. |

Metro Vancouver is developing programs to address both residential and industrial/commercial sources of wood smoke.
In partnership with the BC Government, BC Lung Association and several local home heating retailers, Metro Vancouver is working to reduce the use of smoky appliances by providing eligible residents with a rebate when they trade in their old uncertified wood burning appliance for a new low emission appliance. The Metro Vancouver Wood Stove Exchange Program is an initial element of Metro Vancouver’s Residential Wood Smoke Emissions Reduction Program, which may also consider implementing further regulatory initiatives.
In 2008 Metro Vancouver enacted emission regulation bylaws which require wood-fired agricultural and industrial boilers or process heaters to comply with stringent emission limits.

Replace your wood-burning appliance.
Reduce your health risk and save money by participating in the Metro Vancouver Wood Stove Exchange Program. | If you burn wood, burn it smart.
Improve the efficiency of your appliance and reduce woodsmoke by using “Burn it Smart” techniques, such as making sure fires are small and hot and by burning only dry, seasoned wood. Avoid burning any materials not intended for use in fireplaces and wood stoves, such as plastics, styrofoam, painted wood, plywood, driftwood and household rubbish. For more information see Tips for Safe & Efficient Woodburning. | Spurn the burn outdoors.
Chip or compost your yard waste instead. Anyone who wishes to conduct outdoor burning must contact their local municipality for approval before starting and take precautions to follow all municipal requirements and provincial regulations. Unauthorized outdoor burning should be reported to your local fire department. | Spread the Word.
Educate your neighbours, family and friends about reducing wood smoke. |

Fast Facts
What’s in woodsmoke?
Environment Canada and Health Canada have identified many hazardous chemical substances in wood smoke: |
|
| Acrolein: | Acrolein can cause eye and respiratory tract irritation. | | Carbon monoxide (CO): | CO can reduce the blood’s ability to supply necessary oxygen to the body’s tissues, which can cause stress to the heart. When inhaled at higher levels, CO may cause fatigue, headaches, dizziness, nausea, confusion and disorientation and, at very high levels, lead to unconsciousness and death. | | Dioxins and furans: | Some dioxins and furans are carcinogenic. | | Formaldehyde: | Formaldehyde can cause coughing, headaches and eye irritation and can act as a trigger for people with asthma. | | Nitrogen oxides (NOx): | NOx can lower resistance to lung infections. In particular, nitrogen dioxide can cause shortness of breath and irritate the upper airways, especially in people with lung diseases such as emphysema and asthma. | | Particulate matter (PM): | A microscopic mixture of particles of varied size and composition, PM has been declared a toxic substance under the Canadian Environmental Protection Act. These particles can be inhaled deep into the lungs, leading to serious respiratory problems, hospital admissions, and sometimes premature death. | | Polycyclic aromatic hydrocarbons (PAHs): |
Prolonged exposure to PAHs is believed to pose a cancer risk. | | Volatile organic compounds (VOCs): | VOCs can cause respiratory irritation and illness. Some VOCs emitted by wood-burning appliances, such as benzene, are known to be carcinogenic. |
