Wildfire Smoke May Spark Heart Troubles. (Houtrook veroorzaakt hartfalen)

Fine particulate matter linked to acute coronary events, especially in elderly.


Exposure to fine particulate matter air pollution during wildfires may increase risk for cardiac arrest and other acute heart problems, particularly in the elderly, according to Australian researchers.

The time-stratified case-crossover study, which looked at cardiovascular and respiratory health effects of wildfire smoke (PM2.5; aerodynamic diameter <2.5 lm) from the 2006-2007 bushfires in Victoria, Australia, showed a 6.98% increase in cardiac arrest when ambient air is contaminated by smoke from wildfires, reported Anjali Haikerwal, MBBS, MPH, of Monash University in Melbourne, and colleagues.


Associations were observed for out-of-hospital cardiac arrests, hospital admissions, and emergency department (ED) visits for ischemic heart disease (IHD) after two days of exposure to wildfire smoke in Victoria at PM2.5 concentrations, they wrote in the Journal of the American Heart Association.

This association was observed mainly in adults 65 or older. Men showed a higher risk of out-of-hospital cardiac arrests events and women showing a higher risk of IHD-related hospital admissions, they added.

“The results from our study suggest that PM2.5 exposure from wildfire smoke may be an important determinant of out-of-hospital cardiac arrest and IHD (ED visits and hospital admissions) and that susceptible persons such as older adults may be at higher risk during such extreme events,” Haikerwal’s group wrote.

One of the most important sources of PM2.5 air pollution is from wildfire smoke exposure, the authors pointed out, adding that “smoke from wildfires disperses widelyand affects large portions of the population away from the fire source.”

Protracted droughts make Victoria one of the most fire-prone regions in the world. The 2006-2007 wildfire was the longest running collection of fires that burned over more than 1 million hectares (about 4,000 square miles) of land in Victoria and lasted for more than 60 days.

Previously, she noted, epidemiological studies investigating the role of fine particulate matter in triggering acute coronary events, including out-of-hospital cardiac arrests and IHD, during wildfires, have been inconclusive.

This examination of the associations between of out-of-hospital cardiac arrests, IHD, acute myocardial infarction, and angina (hospital admissions and ED attendance) with PM2.5 concentrations during the 2006–2007 wildfires paints a different picture.

“Their data support previous findings of increased cardiovascular hospital admissions during increased air pollution exposure, and basic studies showing that particulate contamination can alter autonomic activity and negatively affect cardiovascular health,” said Alfred Bove, MD, PhD, a cardiologist at Temple University in Philadelphia, in an interview.

“The findings indicate that patients should be made aware of an increased risk for cardiovascular events during times when air pollution is particularly severe, whether from wildfires, heavy vehicle traffic or other exposures,” he told MedPage Today.

He pointed out that it was likely that many of the subjects who experienced a cardiovascular event had underlying cardiovascular disease. For this reason, “patients with known cardiovascular disease should be instructed to avoid air pollution exposures, and find filtered air environments when pollution levels are high, as in the event of environmental smoke contamination from wildfires,” he said.

Bove added that similar advice is appropriate for those without a history of cardiovascular disease.

The authors acknowledged that a study limitation was the the lack of information on personal risk factors such as socioeconomic status, smoking, obesity, and underlying health conditions. They also lacked data on indoor PM concentrations while the wildfires were raging.

During the December 2006 to January 2007 study period, health data were obtained from comprehensive health-based administrative registries. Modeled and validated air exposure data from wildfire smoke emissions (daily average PM2.5, temperature, relative humidity) were also estimated for this period.

There were 457 out-of-hospital cardiac arrests, 2,106 ED visits, and 3,274 hospital admissions for IHD, the authors reported.

After adjusting for temperature and relative humidity, an increase in interquartile range of 9.04 lg/m3 in PM2.5 over two days moving average (lag 0-1) was associated with a 6.98% (95% CI 1.03%-13.29%) increase in risk of out-of-hospital cardiac arrests, with strong association shown by men (9.05%,95%CI 1.63%-17.02%) and by seniors (7.25%, 95% CI 0.24%-14.75%).

Increase in risk was 2.07% (95% CI 0.09%-4.09%) for IHD-related emergency department attendance and 1.86% (95% CI 0.35%-3.4%) for IHD-related hospital admissions at lag two days, with strong associations shown by women (3.21%, 95% CI 0.81%-5.67%) and by older adults (2.41%, 95% CI 0.82%-5.67%).

PM2.5 levels during wildfire episodes can exceed air quality guidelines set by regulatory bodies such as the World Health Organization, the authors stated, adding that it has long been hypothesized that PM2.5 is particularly toxic because it can penetrate deep into the lungs and induce systemic and oxidative stress responses.

This in turn could potentially trigger a cascade of pathophysiological events and lead to manifestations of CHD, including chronic and angina, plaque instability, and rupture, typically following myocardial infarction and cardiac arrest, they said.

“Given the increased incidence and frequency of wildfires recently and the increased number of people at risk of smoke exposure, future research is required to investigate the role of fine particulate matter exposure from wildfire smoke in triggering acute coronary events,” they concluded. “The knowledge and evidence resulting from such research will inform policy and practice and help build capacity in the understanding and management of adverse cardiovascular health impacts in vulnerable communities during wildfire episodes.”

New medical research has confirmed exposure to smoke from bushfires can be as damaging as cigarette smoke.

New medical research has confirmed exposure to smoke from bushfires can be as damaging as cigarette smoke.

Laboratory tests on human lung cells by the Woolcock Institute of Medical Research in Sydney show bushfire smoke can scar and inflame lungs, just as cigarettes do.

“We take cigarette smoke exposure very seriously,” said cell biologist Brian Oliver.

“Our evidence suggests it might be time to do the same with wood smoke and try to minimise exposure.”

Air pollution is known to soar during bushfires.

Between 1994 and 2007, bushfires in Sydney, Wollongong and Newcastle were associated with increased hospital admissions for asthma and other respiratory illnesses.

During the fire emergency in the Sydney region in October last year, residents were warned about tiny particles from bushfire smoke that go deep into the lungs and irritate the airways.

Dr Olivier said the Woolcock study focused on the potential role wood smoke played in triggering chronic obstructive pulmonary disease (COPD), which attacks and destroys lungs.

The two main forms of COPD emphysema and chronic bronchitis, and COPD affects one in 13 Australians aged over 40, usually due to smoking.

Researchers say the study also raise concerns about the effects of using wood for heating and cooking in developing countries.

“The smoke we inhale from burning biomass fuels can do long-term lasting damage to our lungs,” Dr Olivier said in a statement.

The findings were published in the international scientific journal PLOS ONE, an open access peer-reviewed publication.

Brandlucht door paasvuren in heel Nederland

In het Groningse Roodeschool hing vanochtend smog, afkomstig van de paasvuren net over de grens. Door het hele land zijn er meldingen van een ‘brandlucht’ veroorzaakt door de Paasvuren.

Het grootste paasvuur brandt dit jaar in Espelo

In het Overijsselse Espelo staat een paasvuur van 15,43 meter hoog. Het heeft een omtrek van 108 meter. Espelo heeft daarmee het grootste paasvuur van 2014.

“Ons vuur heeft een inhoud van 4801 kubieke meter. De concurrent in Dijkerhoek heeft 4152 kubieke meter”, zegt Arjan Stevens van het paasvuur in Espelo.

Gistermiddag leek het even mis te gaan, toen de top van het paasvuur omviel. Maar de bouwers wisten die te repareren. Vanavond om 21:00 uur wordt het vuur aangestoken.

In 2012 bouwde Espelo het grootste paasvuur ter wereld. Het was toen 45,98 meter hoog en had een omtrek van 160 meter. Een cameraman van RTV Oost raakte zwaargewond toen het vuur brandde, doordat een staalkabel knapte.


Quebec introduces plan to eliminate old wood stoves

MONTREAL – There are about 85,000 non-certified wood burning stoves in Montreal and the Quebec government has announced a plan designed to eliminate them.

The province has set aside $6 million to offer stove owners rebates to exchange their stove with one that is more environmentally friendly.

Rebates for one of the new stoves or heating alternatives, which include wood pellets and propane, range from $300 and $900.

Wood stoves are a major cause of bad air quality during the winter in Montreal and can lead to certain diseases of the heart and lungs, according to Equiterre.

Those interested in taking part in the program are advised to contact the environmental group Equiterre.

“People who have wood stoves, their first step should be to contact us,” Sydney Ribaux of Equiterre told CTV Montreal.

The program begins this fall. For more information visit the group’s website.


Hout stoken bijzonder gevaarlijk voor kinderen……

Wood burning is child abuse


If you saw a photo like this would you consider it child abuse?


Or how about this one?


Now consider the effects that smoke has on young lungs?


Now consider that wood smoke has many of the same harmful chemicals that tobacco smoke has and that some studies say that woodsmoke is even more harmful than tobacco smoke. Then it is easy to say that this is what wood smoke is doing to young lungs and that it too is a form of child abuse.


And this is therefore also a form of child abuse:


And this is also a form of child abuse:


There are no proven safe limits of particulate pollution. It harms at all concentrations. It harms the young. It harms newborns. It harms the yet to be born. It harms the old. It harms everyone.

It is completely immoral to burn wood if a child is going to be breathing in the smoke. It is completely immoral to burn wood if anybody is going to be breathing in the smoke.  If you don’t agree then you do have the morals of someone who deliberately harms children and what kind of person would deliberately do that?

No Shit Sherlock!!!!


“The air is not as clear in Napier as previously thought – with monitoring showing pollution from winter fires is much higher in some suburbs than others.” – from this story on Stuff.

Well No Shit Sherlock!!!

If they measure it in suburban places where they haven’t measured it before , why the hell are they surprised that there is poor air quality?

It’s the same old story. There are too many woodburners and they just don’t do enough monitoring.

The ambient air quality standards (of PM10 50ug/m3 averaged over 24 hours, with no more than 1 exceedance a year) are a shit standard that allow for much harm and death and really should be tightened, but the aim shouldn’t be to just comply with them. The aim should be to get as close to zero as possible.

From another news story, this time on ABC Australia:

“Deadly air pollution continues to be a problem in Australia because air quality standards are being misused, say experts.

The standards governing six key outdoor pollutants are being interpreted as an acceptable upper limit of pollution, says health statistician Associate Professor Adrian Barnett of the Queensland University of Technology.

But, he adds, this approach is not supported by scientific evidence.”
To paraphrase the A. Professor: “He says many reports to state governments imply it is safe to pollute up to the limits provided in the National Environment Protection Measure for Ambient Air Quality (Air NEPM), but the governments are getting bad advice.”

113 people die each year in Hawke’s Bay. 1175 across all of New Zealand.

They die because politicians have failed at their jobs. The current policies around wood burning are what you get when there is a systemic failure of our governance. They are what we get when we have dumb and gutless politicians.

Wiseup thicko politicians. People are dying on your watch.

We could do more monitoring, paid for by putting an annual tax on woodburners. but the monitoring will tell the same story. Woodburners make pollution. It’s all wood burners. It’s all solid fuels. How much evidence do we need to go to a full ban on all sold fuel burning? We should be tracking at background particulate levels, not bumping around at 50 micrograms of PM10s. Of course we need a ban. It’s elemental my Dear Watson.


Wood Smoke and DNA Damage


EPA picture simulating how Polycyclic Aromatic Hydrocarbons, (PAH) adhere to DNA ( see the white patch).


 Wood smoke particles generate free radicals and cause lipid peroxidation, DNA damage, NFkappaB activation and TNF-alpha release in macrophages.

Pathology and Physiology Research Branch, Health Effects Laboratory Division, National Institute for Occupational Safety and Health, M.S. 2015, 1095 Willowdale Road, 26505-2888, Morgantown, WV, USA.

The present study investigated the generation of free radicals by wood smoke and cellular injuries caused by these radicals. Wood smoke was collected after thermolysis of western bark. Electron spin resonance (ESR) techniques were used to measure both carbon-centered radicals and generation of reactive oxygen species (ROS) by wood smoke. Wood smoke, in the presence of H(2)O(2), was found to be able to generate hydroxyl radical (.OH). DNA strand breakage was measured by exposing wood smoke to lambda Hind III fragments using gel electrophoresis. Wood smoke combined with H(2)O(2) caused DNA damage. Sodium formate, an .OH radical scavenger, or deferoxamine, a metal chelator, inhibited the DNA damage. Cellular DNA damage was also measured in cultured RAW 264.7 mouse macrophage cells by the single cell gel (SCG) electrophoresis assay. Cells were exposed to wood smoke samples for various times and significant DNA damage was observed. Elemental analysis was performed on the filter samples and the presence of Fe was noteworthy. Wood smoke is also able to cause lipid peroxidation, activate nuclear transcription factor, NFkappaB, and enhance the release of TNF-alpha from RAW 264. 7 cells. The results indicate that the free radicals generated by wood smoke through the reaction of Fe with H(2)O(2) are able to cause DNA and cellular damage and may act as a fibrogenic agent.
