A wood stove is over 500 times dirtier than a
modern oil burner and a 1000 times dirtier
than heating with gas! (Pugent Sound Air Pollution Control Agency, WA, USA 1996)
Heating with a wood
stove for one season generates as much pollution
as driving a car 130,000 miles.

2 With all of this information,
wouldn't you think that
every child might:
Live in a smoke-free and clean energy,
non-wood-burning home and learn in a smokefree
Expect education, athletic and recreation
facilities to be smoke-free, so that scholastic
and athletic achievements are not limited by
uncontrolled asthma and lost school days due to
Be cared for by a supportive physician
who explains to parents and teachers the dangers
of wood smoke and tobacco smoke and
their role in causing: asthma, immune system
damage leading to auto-immune diseases,
respiratory damage, increased risk of infection,
aggravation of heart disease, and cancer.
Learn self-management skills to minimize
exposure to smoke and to have confidence
they will not be exposed to hazardous combustion
toxins contained in tobacco smoke and
wood smoke whether at home, school or play.
Expect adults entrusted with their care
to understand how to handle pollution emergencies
and expect public guardians to protect them
from smoke and other hazardous pollutants.
3 In the last 10 years the number of children
suffering from asthma has doubled.
According to a survey by the CDC, one
child in seven (8.6 million nationwide) has been
diagnosed with asthma, and the numbers have
been growing at an alarming rate. It is the most
common childhood disease and the leading
cause of absenteeism from school.
The largest single source of outdoor
fi ne particles (PM2.5) in many American and Canadian cities
is our neighbor's fi replace or wood stove.
particulate matter in wood smoke is so small
that closed doors and windows cannot stop it
from entering, even in newer energy-effi cient
weather-tight homes. 90% of wood smoke
is in the tiny size particle range (PM2.5)
averaging less than 1 micron (one millionth of
a meter),  
allowing the fi ne particles to remain
airborne for up to 3 weeks. 
The particles are so
small that they can penetrate into the deepest
recesses of the lungs.
These particles become
effi cient vehicles for transporting toxic gases,
bacteria and viruses deep into the lungs where
they do the most damage and cannot be coughed
up, and from where the chemicals pass directly
into the blood stream.
Tobacco smoke and wood smoke are
very similar in chemical composition.
the chemicals and gases of wood smoke
and tobacco smoke has been linked not only to
health problems, but also to substance abuse.
There is concern that children from areas with
high levels of wood smoke may be more likely
to begin smoking tobacco. 
Homes in wood burning areas also have
increased rates of low birth weight and Sudden
Infant Death Syndrome, (SIDS).
We can reduce our children's exposure
to toxic pollutants by taking very simple measures
in our daily lives: avoiding the use of
wood burning appliances and tobacco. Many
lives could be saved at little or no cost.

5 Breathing in wood smoke
is comparable to inhaling
second-hand cigarette smoke.
Many of the pollutants are similar to
those produced by burning tobacco. The EPA
estimates that wood smoke is 12 times more
carcinogenic than equal amounts of tobacco
smoke and attacks our body cells up to 40
times longer than tobacco smoke.
A single fi replace operating for an hour
and burning 10 pounds of wood during that time
will generate 4,300 times more carcinogenic
polycyclic aromatic hydrocarbons than 30 cigarettes.
The threat to human health comes
from the fi ne particulate matter - tiny particles
1/200th the size of a raindrop. Inhaling
wood smoke particulate matter increases the
incidence, duration and severity of respiratory
disease, striking hardest at children,
the elderly and those with lung or heart disorders.
The EPA warns that there is no safe
level of these carcinogens.
US EPA 
Fireplaces and wood stoves are estimated
to be the origin of 35% of fine-particle
pollution as a national average. 
Each pound of
wood burned costs the entire community $2 in
increased medical costs and lost work days.
That is equivalent to $40 for an average fi re
burning 20 pounds of wood. 
Air pollutants also cause immune system
damage, which can lead to asthma, allergies and
Air pollutants have also
been linked to psychological disorders and
toxic damage to the nervous system and the
brain, especially in developing fetuses or young
The number of deaths attributed to particulate
pollution exceeds the number of deaths
from major cancers like breast cancer and prostate
cancer and exceeds the deaths occurring
from auto accidents by more than 50%.

have healthier heating and cooking options.
Re-establish the right of every citizen
in this country to breathe clean air and not be
detrimentally impacted by fi ne particulate pollution.
As population densities increase, wood
burning becomes even more inappropriate
because smoke toxins cannot be prevented from
crossing property lines. 
Indoor PM2.5 levels
from wood smoke in homes without wood
stoves reach at least 50-70% of outdoor levels.
When your neighbor is burning wood, deadly
pollutants are inside your house as well.
Protect yourself and your children.
