This may be one of the reasons why exposure to wood smoke increases susceptibility to respiratory infections. It is also known to, in demyelinating diseases such as multiple sclerosis. found that dioxin levels rose ten times above background levels when wood stoves were in use. However, wood burning emits high levels of harmful particulate pollution, toxins, short-lived climate pollutants and other compounds. An Italian study found that benzo(a)pyrene levels were highest in “peripheral areas” where the major source of pollution was residential wood burning, rather than vehicles. to be discovered. It is the same, harmful chemical. Arsenic that is released by burning becomes attached to fine particles in the air that may travel for days over long distances, eventually winding up in soil or water. As a World Health Organization fact sheet states: “The air pollutant linked most closely to excess death and disease is PM2.5”. Some types of wood are really poisonous to burn in the fireplace. It was also noted that black carbon from wood smoke was also present in non-wood-burning homes, due to infiltration from outside. Once in the atmosphere, PAHs react with light and oxygen to form secondary compounds. Residential wood burning is the most significant source of  mutagenic and carcinogenic PAHs in many countries around the world. For more information about wood burning and environmental issues, please follow these links: Home |  Health | Residential Burning | Public Spaces | Environment | Resources | About Us, Doctors and Scientists Against Wood Smoke Pollution © 2020, Because wood is natural and trees can be replanted, some people believe that burning wood is better for the environment than using fossil fuels. For example, this study of a typical residential area in Finland showed that wood combustion contributes as much as 70% to local benzene sources. Once in the atmosphere, PAHs react with light and oxygen to form secondary compounds. There are several types of aldehydes in wood smoke, including acetaldehyde, which is a probable carcinogen, formaldehyde, which is a known carcinogen, and acrolein. According to the Australian Air Quality Group, this makes the average wood stove as polluting as 2,200 gasoline-fueled passenger cars. Mercury, which is a neurotoxin, is classified as a persistent bioaccumulation toxic (PBT) by the US EPA. According to the American Lung Association, wood-burning stoves produce harmful toxins that can damage your lungs and increase the risk of cancer, heart disease, and premature death. Many people think that cars are polluting, but wood stoves are much, much worse. These woods produce toxic smoke that can be very dangerous. New Zealand, where wood burning is common in winter, ambient arsenic levels have been shown to rise substantially in correlation with wood burning levels. It was noted that earlier studies have found a correlation between childhood ALL and exposure to ambient levels of benzene in the air. extracts from all three locations showed significant mutagenicity in the Ames Test,  compared to 25% in summer. For example, if all the wood burning appliances were to be changed to non-wood-burning heating sources, benzene emissions from residential heating would be near zero. Just like with any wood, pellets emit carbon monoxide gas. )pyrene levels were highest in “peripheral areas” where the major source of pollution was residential wood burning, rather than vehicles. Residential wood burning is a, of dioxins in the United States and is estimated to be the third largest contributor of dioxins to the environment. Wood smoke contains thousands of chemicals, including known irritants, carcinogens, suspected carcinogens. Wood burning creates large quantities of localized outdoor air pollution, which has, a Group 1 human carcinogen by the International Agency for Research on Cancer. You would. Hydroxylated polycyclic aromatic hydrocarbons (OH-PAHs) are oxidation products of PAHs. Wood burning is also a significant source of mercury emissions into the atmosphere. that breathing in acrolein impairs vascular repair, which can lead to increased risk of cardiovascular disease. This may be one of the reasons why exposure to wood smoke increases susceptibility to respiratory infections. s in many countries around the world, including, for example, the, it’s responsible for more than 90% of ambient, has found that residential solid fuel burning, which is almost entirely from wood, is the largest source of environmental, in Seiffen, Germany found that the “presence of short-term events of extremely high PAH concentrations were directly attributed to a plume of chimney exhaust emitted from houses located close to the sampling place.” It was found that residential wood burning was responsible for 62% of the total PAH levels in winter, and that, “The large contribution of the residential wood combustion to the PAH concentration highlights its possible impact on human health, as considered in previous toxicological studies.”, Increased Mutagenicity and Cancer Potency During Wood-Burning Season, compared winter and summer ambient levels of PAHs in three urban areas where most of the particulate pollution in winter is from residential wood burning. An Australian study found evidence that use of a wood stove in the year before or during pregnancy increased the chance of a child developing acute lymphoblastic leukaemia (ALL). Long exposure to this can be harmful, so always try to stand away from being directly in line with smoke emissions coming your way. s can absorb light energy to form reactive oxygen species (ROS) and free radicals. These are some of the most toxic chemicals to which you can be exposed. In addition, research has found that PAHs also have anti-androgenic effects in the womb that may affect the development of reproductive organs. We suggest you to read the best firewood for fireplaces. It doesn’t matter if a carcinogen such as benzene comes from a factory or from a wood stove. damage that is associated with age-related diseases. )pyrene as burning one kilogram (2.2 lbs) of wood. As Oregon State University’s Superfund Research Program tells us, if you want to reduce your exposure to PAHs, “avoid smoke from wood fires, whether from home heating or for recreational purposes.”. But the wintertime level has been shown to rise as high as 90 nanograms/m3 in correlation with wood burning. Women who have detectable PAH-DNA adducts, to have an increased risk of hormone receptor-positive breast cancer. that residential wood burning is responsible for 38% of formaldehyde emissions in the Sydney region. (The study also noted that, in addition to benzene, wood stoves are also a “notable source” of toluene and xylenes.) Although the smoke from burning other woods is also harmful to health, smoke from toxic woods is much more dangerous. Residential wood burning is a significant source of dioxins in the United States and is estimated to be the third largest contributor of dioxins to the environment in Europe . Many people think that cars are polluting, but wood stoves are much, much worse. You would have to light 27,333 cigarettes to emit as much benzo(a)pyrene as burning one kilogram (2.2 lbs) of wood. Wood burning also emits short-lived climate pollutants such as black carbon, brown carbon, methane and carbon monoxide, and. A Swedish study found that wood-burning homes had 3- to 5-fold higher levels of several hazardous PAHs, and roughly 4 times the total PAH cancer potency, compared to non-wood-burning homes.
