Health Effects of Wood Smoke Pollutants

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.)

Table 3: Wood Smoke Pollutant Health Effects

Wood Smoke Pollutant

Health effect
Carbon Monoxide1 Poison: resulting change of oxyhemaglobin carboxyhemoglobin. Tissue hypoxia, cellular death, damages to the central nervous system, death. 14 Causes reproductive toxicity.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
Acrolein 1 Toxic, Bronchopneumonia, aveolitis, swelling and hemorrhaging of tiny vessels.16
Propionaldehyde1 Toxic 11
Butryaldehyde1  
Acetaldehyde1 Toxic 11 , degeneration of olfactory epithelium, liver lesions, nasal cancer, growth retardation.16
Furfural1 Irritates mucous membranes, causes headaches and photo-sensitivity and affects sugar metabolism. 14
Substituted Furans1  
Benzene1 Colorless volatile liquid. 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 toxicity.15 Accumulates in blood and subcutaneous fat if insufficient clearance time between exposures. Irritates eyes and upper respiratory tract. Toulene interacts 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.
Acetic Acid1 Irritant
Formic Acid1 More irritating than acetic acid. Dangerously caustic to the skin. 14
Nitrogen Oxides (NO,NO2)1 Lung damage. Illnesses of breathing passages and lungs (respiratory system). Acid aerosol which damages trees and lakes. 11
Sulfur Dioxide1 Insecticide. Breathing problems, may cause permanent damage to lungs. Environmental effects - SO2 is an ingredient in acid rain (acid aerosols), which can damage trees and lakes. Acid aerosols can also reduce visibility.

Impairment of neurobehaivior function: slowed visual reaction time, erratic fine hand, and forearm movement, finger tremor, affects audio verbal short term memory. Causes fatigue, tinnitus, irritability, and more coughs and acute bronchitis.16, Central nervous system is the primary target. Lodges in lung, providing a pool of slowly released manganese that eventually penetrated the brain. Half-life in the brain of about one year, concentrating in the basal ganglia, which are the brain structures critical for movement. Even modest levels are cumulative.17
