Wood smoke forms when wood or other organic matter burns. Wood smoke is actually made up of a complex mixture of gases and fine particles, some of which are small enough to enter your lungs. In addition to particle pollution, wood smoke can contain some toxic air pollutants, such as benzene, acrolein, formaldehyde, and polycyclic aromatic hydrocarbons (PAHs).
The more efficiently that wood is burned , the less that this type of wood smoke is created. This would include using dry seasoned firewood and by using an EPA-certified wood stove.
These indoor air pollutants can be avoided by converting your firewood-based fireplace into a natural gas log fireplace or using a natural gas powered heater. Pittsburgh Gas Grill and Fireplace company has been helping Pittsburgh-area homeowners with these since 1986.
