At-Home Safety: Air Pollutants from Fireplaces, Wood-Burning Stoves Raise Health Concerns

Feb. 7, 2011
With millions of people warding off winter’s chill with blazing fireplaces and wood-burning stoves, scientists are raising red flags about the potential health effects of the smoke released from burning wood.

A study published in Chemical Research in Toxicology found that the invisible particles inhaled into the lungs from wood smoke may have several adverse health effects.

Steffen Loft, Ph.D., and colleagues cite the abundant scientific evidence linking inhalation of fine particles of air pollution – so-called “particulate matter” – from motor vehicle exhaust, coal-fired electric power plants and certain other sources with heart disease, asthma, bronchitis and other health problems. However, relatively little information exists about the effects of wood smoke particulate matter (WSPM), even though millions of people around the world use wood for home heating and cooking and routinely inhale WSPM.

The scientists analyzed and compared particulate matter in air from the center of a village in Denmark where most residents used wood stoves to a neighboring rural area with few wood stoves, as well as to pure WSPM collected from a wood stove. Airborne particles in the village and pure WSPM tended to be of the most potentially hazardous size – small enough to be inhaled into the deepest parts of the lungs.

WSPM also contained higher levels of polycyclic aromatic hydrocarbons, which include “probable” human carcinogens. When tested on cultures of human cells, WSPM caused more inflammation and damage to the genetic material and had greater activity in turning on genes in ways linked to disease.
