Canadian Cancer Society (Why I no longer support this organization)

Like many health organizations, the Canadian Cancer Society condemns smoking, but turns a blind eye to residential wood burning.

FACTS:
Air pollution and particulate matter were both classified by IARC as Group 1 carcinogens in 2013.
That means “CARCINOGENIC TO HUMANS”.
Anyone near a wood fire is exposed to a megadose of particulate matter.

In 2016 Public Health Ontario and Cancer Care Ontario jointly published a report entitled The Environmental Burden of Cancer in Ontario, in which they ranked 23 environmental carcinogens.
Fine particulate matter (PM2.5) ranked #3, far ahead of other well-recognized carcinogens such as asbestos, formaldehyde, and secondhand [tobacco] smoke.

Despite the evidence, the Canadian Cancer Society website has minimal warnings about wood smoke.

Using the website’s search function, there are no hits for the term “PM2.5”
“Particulate matter” retrieves the pages “Air Pollution and Cancer” and “Risk factors for lung cancer”, although neither links PM to recreational wood burning.
But wait; here it is!  Buried WAY down, under the heading “Pollutants from cooking and heating”, we find:  “Burning wood and other fuels, such as dung or grass...can also increase the risk for lung cancer.
And a second mention, on the “What is air pollution” page, where “indoor burning of coal or wood” is listed as a major source of indoor air pollution.
On the “7 ways to reduce your exposure to air pollution - indoors”, we finally find a piece of good advice: “Switch from a...wood-burning heat source...”, unfortunately followed immediately by this howler:  “...lower your risk by using efficient stoves and fireplaces with effective chimneys.”

There is no mention anywhere about RECREATIONAL wood burning:  backyard fire pits, campfires, or fireplaces.

Why isn’t residential wood burning treated like smoking?
This message should be upfront on the website, where the public is encouraged to “Make healthy choices”.

Heart & Stroke (Why I no longer support this organization)

Way back in 2009, H&S published a position statement entitled “Air Pollution, Heart Disease and Stroke”.
In this document they:
  • Linked air pollution with premature deaths
  • Recognized wood stoves and fireplaces as “sources of dangerous air pollution” and PM2.5
  • Described the ways PM2.5 affects the cardiovascular system and increases the risk of heart disease and stroke
  • Recommended that public take action to reduce air pollution by limiting wood burning
Strangely, a decade later, none of this information is reflected in the front end of the H&S website.
Evidence that air pollution, PM2.5, and wood smoke have a detrimental effect on the cardiovascular system has increased, and yet residential wood burning is not included among “lifestyle risk factors”.  There are no warnings about inhaling wood smoke.
“Particulate” and “PM2.5” retrieve nothing in the H&S website search function.

There is even Canadian research showing the link between heart attacks in seniors and wood burning:
https://www.cantechletter.com/2017/03/wood-burning-stoves-fireplaces-increase-risk-heart-attack-canadian-study/

Bizarrely, in 2017 H&S used an image of a fire pit in their lottery brochure:


WHY WON’T HEART & STROKE TELL CANADIANS THE TRUTH ABOUT THEIR FIREPLACES, WOOD STOVES, CAMPFIRES AND FIRE PITS?

The position statement can still be found [archived] on the website...if you know where to look:

Diabetes Canada (Why I can’t support this organization)


More evidence of the general level of ignorance, even in the healthcare community, of the dangers of localized air pollution and biomass combustion.

Like other health-related charities, Diabetes Canada condemns tobacco use:

Smoking is a deadly habit. One of the best things you can do for your heart, diabetes and overall health is to quit now.

And then they post THIS image promoting their camps:  child and teens inhaling toxic wood smoke.





On their page “Diwali and Diabetes”, one of the gift basket suggestions is a source of indoor air pollution:

Although exposure to fine particulate is a known risk factor for the development of diabetes, the terms “particulate”, “PM2.5” and “air pollution” yield no useful results when searched on their website.

Lung Association (Why I no longer support this organization)


The Lung Association appears to be either
1) ignorant of all the health issues associated with air pollution, wood smoke, and PM2.5, OR
2) unwilling to offend or alienate the wood-burning public by telling the truth.

Concerning fireplaces, we are told to “burn smart”, properly install and maintain, store wood properly, and (laughably) “...open a window a little bit to ensure a good supply of fresh air into your home.”  ðŸ¤£ðŸ¤£ðŸ¤£
Did HPBCA, WETT, or another industry organization write this nonsense?
Shouldn’t the Lung Association condemn residential wood burning as strongly as it condemns smoking???

Do you have a fireplace in your home? Wood burning indoors can produce high levels of dangerous particles and gases that can be easily inhaled into the lungs. Be sure to "burn smart" if you use a fireplace.

https://www.lung.ca/lung-health/air-quality/your-healthy-home/healthy-home-tour/living-room

Many Canadian homes have fireplaces for ambience and extra warmth. Some homes burn wood as the main source of heat. It is important to follow a number of key steps when burning any wood indoors.

Tips:

  • Inspect your chimneys and flues annually for corrosion, blockages, and cracks that could let dangerous gases (e.g. carbon monoxide) enter your home.
  • When using your fireplace, open a window a little bit to ensure a good supply of fresh air into your home.
  • Do not burn plastics, newspapers, magazines, painted wood, or cardboard as they can all release dangerous chemicals into your home's air.
  • Make sure wood is stored outdoors, dried, kept off the ground, and loosely covered.
  • When installing a fireplace, be sure that it is installed by a certified contractor who will ensure proper installation and safety. Check to see if they are a Wood Energy Technical Training (WETT) certified member.
  • Poorly maintained and inefficient fireplaces can lead to difficulty breathing, coughing, irritation of the lungs, and asthma attacks in sensitive individuals.
  • Ensure your wood burning appliances are being used properly and not causing breathing problems or making air unpleasant for your neighbours.


SHOCKINGLY  bad advice offered about outdoor burning:  
1) no distinction concerning fuels (wood, charcoal, gas, propane)
2) implying these activities are safe under appropriate air quality and weather conditions, and if “not located too close to the home”

In reality a wood burning fire pit will blanket an entire neighbourhood with toxic smoke.

Barbequing and sitting around the backyard fire pit are common Canadian summertime activities. It is important to use them properly to prevent any health issues from exposure to pollutants.

  • Monitor your air quality and weather forecast to determine wind conditions and any air alerts that may be occurring when you're planning on using a barbeque or fire pit. Try not to do any outdoor burning on a hazy or smog day, when the air quality reading is poor, or when there is no wind as it will keep wood smoke particles close to the ground where people can inhale them. Also, do not light a fire pit during windy conditions as this can cause sparks to fly around and cause the fire to get out of control.
  • Make sure your barbeque or fire pit is not located too close to the home as any drifting smoke can easily get indoors through windows or doors.

Fire Pit Emissions (To Council, #8)

Today I would like to direct your attention to the 2013 decision by the South Coast Air Quality Management District in California, regarding beach bonfires:
Some key points to note:

“The particulate emissions rate per minute from one beach bonfire is equal to that from: 
  • Three average big-rig diesel trucks; or 
  • The secondhand smoke from 800 cigarettes. Wood smoke contains many of the same toxic chemicals as secondhand cigarette smoke.”

 “...one fire pit in one evening emits as much fine particulate pollution (PM2.5) as one big-rig diesel truck driven 564 miles.”

“Smoke does disperse and is diluted as it travels downwind from a fire pit. An air quality model indicates that the concentration of PM2.5, the key harmful ingredient in wood smoke, decreases by about 98 percent at a distance of 700 feet from a fire pit...”

“Fine particles in wood smoke contain cancer-causing chemicals as well as common combustion pollutants such as nitrogen oxides. Numerous health studies during wildfires, and in communities where large amounts of wood or other biomass is burned, show that wood smoke causes respiratory irritation and an increase in hospital admissions for respiratory problems. Fine particles also can aggravate chronic heart and lung diseases and are linked to premature deaths in people with these conditions.”

SCAQMD’s decision is that fire pits can remain if they are “located at least 700 feet from the nearest residence”.


I am waiting to hear your justification for allowing backyard fire pits in Woodstock.

Open Air Burning and Children (To Council, #7)

Just like second-hand tobacco smoke, wood smoke is hazardous to infants, children, and the unborn.

You are probably aware that in Ontario it is illegal to light a cigarette in a vehicle with a child on board, and it is also illegal to smoke within 20 metres of a playground or playing field.  Our provincial government is well aware of the danger posed to children from smoke inhalation.

Bizarrely, in Woodstock it is legal for many residents near parks and playing fields to light backyard fires, thus subjecting children and their families using these facilities to toxic wood smoke. 
Please ponder the irony implicit in the attached picture, taken at Cowan Park:  no  smoking, but a fire pit (one of many in the neighbourhood) in the background.

Here are some excerpts from the website of Doctors and Scientists Against Wood Smoke Pollution:
“Children are among the most vulnerable to the harmful effects of particulate air pollution. Children breathe faster and inhale more pollutants in proportion to their body weight than do adults. Their immune systems and organs are still developing.”
“Particulate pollution has been shown to affect lung function and lung development.”
“During infancy, the developing lung is highly susceptible to damage from environmental pollutants, including those from wood smoke.”
Recent research also suggests an association with increased exposure to fine particulate matter during pregnancy and an increased risk of stillbirth.”
“There is also growing evidence that fine particulate pollution, especially with increased levels of PAHs, can lead to impaired neuropsychological development and a lifelong lowered IQ.”
“As a society, we no longer think it is acceptable to force children to breathe secondhand tobacco smoke. It’s time to extend this attitude to wood smoke.”


Why does Woodstock allow open air burning?

Open Air Burning and Dementia (To Council, #6)

If physical health problems previously discussed (cancer, diabetes, heart attacks, COPD, and asthma) aren’t enough reason to fear wood smoke, please be advised that there is evidence that PM2.5 attacks the brain, and leads to various forms of impairment, including dementia.

A recent study conducted in Ontario found a positive relationship between PM2.5 and dementia, and between nitrogen dioxide and dementia.  PM2.5 and nitrogen dioxide are both components of wood smoke.

Here is an accessible article that quotes the study:

Follow that with this study from Sweden:
“Researchers at the Umea University in northern Sweden have studied air quality in homes where wood-fire stoves are used and found that inhaling smoke from the stoves may not only cause asthma and increase the risk of cardiovascular diseases, but can also enhance the risk of the onset of dementia...
"We have seen that people who live in areas where wood-fire stoves are common run a greater risk of being affected, and that also goes for people who live next to someone who uses wood-fire stoves,"...

Results from the Swedish study:
“The emission of PM2.5 from local residential wood burning was associated with dementia incidence with a hazard ratio of 1.55 for a 1 μg/m3 increase in PM2.5...
Study participants with an address in an area with the highest quartile of PM2.5 from residential wood burning and who also had a wood-burning stove were more likely to develop dementia than those in the lower three quartiles without a wood-burning stove...”

Wood smoke is hazardous to mind and body.

Why does Woodstock Council allow open air burning?

Open Air Burning and Asthma (To Council, #5)

You probably know someone who suffers from asthma; according to Health Canada, this chronic condition afflicts 12.1% of the population of Ontario.

If you have been following the news about the forest fires elsewhere in the province, you may have heard special warnings directed at people who suffer from asthma, as well as for those with COPD, or other respiratory or cardiovascular problems.

What you should realize is that inhaling smoke from neighbourhood fire pits is just as dangerous as inhaling forest fire smoke.

Here is more information from the Lung Association, Asthma Canada, and the Government of Canada:

“Breathing in wood smoke can cause increased respiratory symptoms, increased hospital admissions, exacerbation of asthma and COPD, and decrease your ability to breathe normally. If you have a lung disease, breathing in wood smoke can make your disease worse and cause a flare-up.”

“Exposure to smoke of any kind, whether the source is tobacco, marijuana, forest fires or camp fires, can be harmful.”

“Asthma is one of the most common chronic respiratory diseases in Canada. It affects Canadians of all ages, but younger Canadians are disproportionately affected.
Symptoms of asthma include shortness of breath, wheezing, coughing, and chest tightness. There is currently no cure for asthma; however, it can be well controlled by maintaining a healthy lifestyle, avoiding allergens and other triggers, quitting smoking, and taking medication properly.”

The number of residents of Woodstock who suffer from asthma is probably close to 5,000.
(2016 census population: 40,902 x provincial asthma rate 12.1%) = 4,949.


Now that you know that wood smoke may be triggering asthma attacks in approximately 5,000 residents (many of them children), how can Woodstock Council justify continuing the practice of open air burning?

Open Air Burning and COPD (To Council, #4)

You probably know someone who is suffering from COPD; more than 10% of Canadians over the age of 35 are living with it.

Wood smoke can cause COPD, precipitate flare-ups, and lead to death.
Here’s what the Lung Association has to say:

Chronic Obstructive Pulmonary Disease (COPD) is a lung disease that includes chronic bronchitis and emphysema.
In 80-90% of cases, it is caused by smoking. Other causes of COPD can include:
  • genetic reasons (alpha-1 antitrypsin deficiency)
  • occupational dusts and chemicals
  • second hand smoke
  • frequent lung infections as a child
  • wood smoke and other biomass (animal dung, crop residues) fuel used for cooking. https://www.lung.ca/copd
Breathing in wood smoke can cause increased respiratory symptoms, increased hospital admissions, exacerbation of asthma and COPD, and decreased your ability to breathe normally. If you have a lung disease, breathing in wood smoke can make your disease worse and cause a flare-up.
PM2.5 (inhalable particulate matter less than 2.5 microns in diameter) - PM2.5, which consists of a mixture of microscopic particles of varied size and composition, has been declared a toxic substance under the Environmental Protection Act. These particles can be inhaled deep into the lungs, leading to serious respiratory problems, including excess mortality, especially among those with pre-existing cardiopulmonary illness.

So we can add COPD to our growing list of health problems (cancer, diabetes, heart attacks) linked to PM2.5 and wood burning.

How can Woodstock Council justify the practice of open air burning?

Open Air Burning and Heart Attacks (To Council, #3)

Saturday July 7 was a horribly smoky, unpleasant evening in my neighbourhood here in Woodstock.

Are you aware that wood smoke causes heart attacks?

The results of a recent Canadian study are summarized here:
“By comparing pollution data from three cities in British Columbia (Prince George, Kamloops and Courtenay/Comox) with hospital admissions, researchers from McGill and Health Canada found that rising concentrations of fine particulate air pollution caused by wood burning were associated with increased hospitalization for myocardial infarction. During the cold season, when pollution from woodstoves is at its highest, the risk of heart attacks among subjects of 65 years and older increased by 19%.
“We noticed that the association was stronger when more of the air pollution came from wood burning, says McGill University professor Scott Weichenthal, lead author of a new study published in Epidemiology.”

Here’s a statement from the American Heart Association:
“In sensitive populations, exposure to PM2.5 for even a few hours or days can trigger cardiovascular disease-related deaths from heart attack, stroke, arrhythmia, sudden cardiac arrest, and heart failure. Short- term increases in PM2.5 levels lead to the early death of tens of thousands of Americans every year.”

PM2.5 is a carcinogen.
PM2.5 increases the risk of developing diabetes.
PM2.5 causes heart attacks.
PM2.5 is a major component of wood smoke.

How can Woodstock Council justify the policy of open air burning?

Open Air Burning and Diabetes (To Council, #2)

Last week I wrote to you about the cancer risk for residents due to exposure to wood smoke and one of its components, fine particulate matter (PM2.5).

This past Friday a new study was published in The Lancet Planetary Health, that links PM2.5 with DIABETES.

From CNN’s report on the study:

"There's an undeniable relationship between diabetes and and particle air pollution levels well below the current safe standards," said senior study author Dr. Ziyad Al-Aly, an assistant professor of medicine at Washington University.
“Particulate or particle air pollution is made up of microscopic pieces of dust, dirt, smoke and soot mixed with liquid droplets. The finest particles regulated by the EPA are 2.5 micrometers; to put that in perspective, a strand of human hair is 70 micrometers, or more than 30 times larger.
Anything less than 10 micrometers can not only enter the lungs, it can pass into the bloodstream, where it is carried to various organs and begins a chronic inflammatory reaction thought to lead to disease.

From the study itself:
“The global toll of diabetes attributable to PM2·5 air pollution is significant. Reduction in exposure will yield substantial health benefits.”

8 years ago, the Sentinel Review reported that residents of Oxford County were already at a higher risk of diabetes, due to obesity.

PM2.5 is a carcinogen.
PM2.5 increases the risk of developing diabetes.
PM2.5 is a major component of wood smoke.
How can Woodstock Council justify open air burning?

I await your response.

Open Air Burning and Cancer (To Council, #1)

On calm summer evenings, many Woodstock neighbourhoods are filled with wood smoke from backyard fire pits.

I would like each member of Council to spend a few minutes perusing a report entitled “Environmental Burden of Cancer in Ontario”, a joint publication from Public Health Ontario and Cancer Care Ontario, available on the internet.
https://www.publichealthontario.ca/en/eRepository/Environmental_Burden_of_Cancer_Key%20Messages_2016.pdf
https://www.publichealthontario.ca/en/eRepository/Environmental_Burden_of_Cancer_in_Ontario_2016.pdf

This report ranks 23 environmental carcinogens, and concludes that 3 of those carcinogens are responsible for 90% of new environmental cancer cases in this province.
One of the top 3 carcinogens is FINE PARTICULATE MATTER (also known as PM2.5), and it is a key component of WOOD SMOKE.

BY ALLOWING OPEN AIR BURNING, WOODSTOCK COUNCIL IS THEREFORE INCREASING THE CANCER RISK FOR EVERY RESIDENT OF THIS COMMUNITY.

One of the reduction strategies for PM2.5 given in the report is “increasing the distance between areas with concentrated combustion emissions and where people live and work.” [p.5] 
Clearly, fires shouldn’t be burning in backyards.

You should notice how far down the list are other substances commonly recognized as carcinogenic, such as asbestos, formaldehyde, and second-hand tobacco smoke.  Consider, too, that there is no way to avoid inhaling wood-smoke-polluted air from a neighbour’s fire pit.

Backyard fires are illegal in many Ontario cities, including Guelph, Waterloo, Brantford and Cambridge.

In light of the cancer risk, I would appreciate hearing your justification for continuing to allow open air burning in Woodstock.

The holiday tradition we would be better off without (2nd edition)


Quiz:  What holiday tradition is bad for everyone's health, and also bad for the planet?
Hint:  "Chestnuts roasting on an open fire..."

Yes, that cheerful wood-burning fireplace that confronts us everywhere in image and song at this time of year, is actually a little toxic incinerator.

Burning wood, leaves, or any other biomass releases carbon and other greenhouse gases into the atmosphere, but perhaps the deadliest component of wood smoke is fine particulate matter (PM2.5).

In a joint publication, Public Health Ontario and Cancer Care Ontario identified PM2.5 as the third greatest environmental carcinogen in this province (way ahead of asbestos, formaldehyde, and second-hand tobacco smoke, for comparison).  Solar UV radiation and radon claimed the first two spots.
If that isn’t enough bad news, a recent study funded by Health Canada and conducted in B.C., found that heart attacks in seniors increased as the level of PM2.5 in the air increased.

This festive season, could we consider the health of everyone around us, and NOT light the fireplace?

Peace, goodwill, clean air, and good health to all.

Heart & Stroke Foundation sends the WRONG message


What's wrong with this picture?


The Heart & Stroke Foundation's brochure advertising their 2017 lottery includes an image of a three-generation family sitting lakeside...AROUND A FIRE PIT!
Yes, yes, the device pictured is actually fuelled by propane, but that fact is disguised by a metal surround, presumably to make it look like the (authentic) wood-burning kind.

The message couldn't be more off base, unless the adults were passing cigarettes to the kids ("Let me light that for you, and then I'll teach you how to inhale!").

It's hard to believe that no one at H&S is aware of recent research connecting wood smoke with cardiovascular issues, such as the study done in B.C. and funded by Health Canada, that found increased levels of fine particulate matter were associated with increased heart attacks in seniors: http://journals.lww.com/epidem/Citation/2017/05000/Biomass_Burning_as_a_Source_of_Ambient_Fine.5.aspx

H&S does have a Position Statement buried on their website entitled "Air pollution, heart disease and stroke", but it hasn't been updated since 2009, and the dangers of burning wood/inhaling particulate matter aren't mentioned in any of the "healthy lifestyle choice" advice offered up front.

The issue is even more disturbing when one considers that the person who disregards all the conventional advice offered on the H&S website (concerning weight, diet, exercise, smoking, medical attention), probably puts only their own health at risk, while the person who regularly burns wood damages the health of their entire community.

It would be wonderful to see the Heart & Stroke Foundation redeem itself from this faux pas by launching a wood-smoke-awareness campaign.

Would you do this to YOUR grandmother?


Outdoor Campfire for residents

On Wednesday, Sept. 21 Woodingford Lodge residents, family members, staff and volunteers gathered around an outdoor campfire beside the community garden for some songs, roasted marshmallows and hot dogs. The Woodstock Fire Department was also on hand to enjoy the event, while ensuring the event went off safely.
Thanks to all of the staff and volunteers who helped make the evening possible!  


Pictures and story are from Oxford County's website: 
http://www.oxfordcounty.ca/Services-for-You/Long-Term-Care

I suppose that this event just illustrates the general level of ignorance regarding WOOD SMOKE in Oxford County.
Apparently no one involved (Long Term Care staff, families, volunteers, and [gasp] the Fire Dept.!) had any qualms about exposing a group of vulnerable residents to a hefty dose of particulate matter (of which the World Health Organization tells us that there is NO safe level of exposure), and all the other toxins that are found in wood smoke.

From the Ontario Ministry of the Environment and Climate Change website:
Air Quality Ontario: Particulate matter
"Exposure to fine particulate matter has been associated with hospital admissions and several serious health effects, including premature death. People with asthma, cardiovascular or lung disease, as well as children and elderly people, are considered to be the most sensitive to the effects of fine particulate matter. Adverse health effects have been associated with exposure to PM2.5 over both short periods (such as a day) and longer periods (a year or more)."

From the DSAWSP website:  https://woodsmokepollution.org/particulate-pollution.html
"Increases in particulate pollution levels can trigger heart attacks, strokes and irregular heart rhythms, especially in those with preexisting heart or lung diseases, and aggravate other lung  diseases such as asthma anCOPD."

"A study of New England Medicare recipients over age 65 determined that the death rate rises for each 10μg/m3 increase in PM2.5, both from short-term and long-term exposure, and even when pollution levels do not exceed US EPA or World Health Organization thresholds."


Should I even mention the carcinogenic food served:  burnt sugar and nitrate-laced processed meat?
