Wood Smoke Pollutant Health Effects looks at current known health effects of each known toxic pollutant in wood smoke. Keep in mind that "the dose is the poison". What may be unnoticed by an adult in the short term may be a dose that is very damaging to a new or unborn baby. What is unnoticed in one individual may damage many other people. The following table as a pdf (size 16 KB). For References for Wood Smoke Tables 1-4 (as pdf)
(Wood Smoke Emissions lists some of the known wood smoke chemicals, with a key for the physical state they are in. The major first portion of the list is from one published study (Larson, 1993), the weight of each of these pollutants per kilogram of wood burned is given. Other species found in other studies are listed as "Additional Wood Smoke Emissions" at the end of Table 1, and are included here for the big picture. Scientists know that there are hundreds, perhaps thousands of compounds, and the compounds are rapidly mixing and changing in the smoke itself. A new paper "Chemical Characterization of Fine Particle Emissions from Fireplace Combustion of Wood Grown in the Northeastern United States" (Fine, 2001) lists several hundred more chemicals. We are not including them in our list but provide the reference and abstract for those interested in further research.)

|
| Carbon Monoxide1 | Poison: resulting change of oxyhemaglobin carboxyhemoglobin. Tissue hypoxia, cellular death, damages to the central nervous system, death. 14 Causes reproductive toxity.15 Reduces ability of blood to bring oxygen to body cells and tissues; cells and tissues need oxygen to work. May be particularly hazardous to people who have heart or circulatory (blood vessel) problems and people who have damaged lungs or breathing passages.11 |
| Methane1 | |
| VOCs (C2-C7)1 | Volatile Organic Compounds cause serious health problems such as cancer and other effects. All VOCs contain carbon. They can cause serious human illness. Hazardous. Causes ozone. Ozone causes breathing problems, reduced lung function, asthma, irritates eyes, stuffy nose, reduced resistance to colds and other infections, may speed up aging of lung tissues. Causes fatigue, generalized depression, increased lethargy or sleep, headaches, substernal pressure, generalized aches and accelerated cardiac action.17 Environmental Effects - ozone can damage plants and trees; smog can cause reduced visibility |
| Aldehydes 1 | |
| Formaldehyde1 | The gas is toxic if inhaled or absorbed through the skin and is carcinogenic. 14 Can Harm Plants.11 |

Harmful by transdermal absorption and acutely toxic by ingestion or inhalation, causing mucous membrane irritation, neurological symptoms, and death due to respiratory failure; chronic exposure may result in bone marrow depression and anemia. 14 Causes reproductive toxicity.15 |
| Alkyl Benzenes 1 | |
| Toluene1 | Toulene is a well known addictive substance. (Glue sniffing) It gives feelings of intoxication. Causes sleepiness, dizziness, headache, muscular weakness, confusion, impaired co-ordination, and visual impairment. It is neurotoxic causing neurobehaivioral changes. Causes changes in Liver and kidneys, erosion of the nose, degeneration of respiratory tract skin. Chronic abuse causes damage to the brain in the cerebral area and causes brain stem atrophy.16 Causes reproductive toxity.15 Accumulates in blood and subcutaneous fat if insufficient clearance time between exposures. Irritates eyes and upper respiratory tract. Toulene intereacts with other human exposures such as alcohol ingestion. Pattern recognition is disturbed, by both Alcohol and Toulene. Toulene effects accuracy more than Alcohol. Toulene combined with Alcohol caused performance and mood to decline more than for either one separately. |
