Few people are aware of the hazards of indoor air pollution.
However, indoor air pollution is very prevalent and can cause myriad health
problems, including asthma, headaches, cancer, and poisoning, if toxins are at
high enough levels. Learn the common sources of indoor air pollution and how to
control them.
Toxins
The following airborne toxins are commonly found inside of
homes.
Radon – a colorless, odorless radioactive gas linked to lung
cancer
Carbon monoxide – also colorless and odorless; can cause
poisoning and death
Chemicals in cigarette smoke – a range of carcinogenic
chemicals that can cause respiratory problems, cancer, and other health
problems
Mold and mildew particles –organic toxins that can cause and
worsen breathing problems, including asthma, and even cause death in small
children, if severe
Volatile Organic Compounds (VOC) – includes various toxic
gases causing a range of health effects, from nausea and headaches to nervous
system damage and liver toxicity
Respirable particles – small bits of matter that can be
inhaled, causing breathing problems and cancer
Sources
So where are all those nasty airborne toxins coming from?
The following products and activities are common sources of the airborne toxins
that cause indoor air pollution.
Cigarette smoke – the source of cancer-causing cigarette
smoke chemicals (obviously); also a source of respirable particles and carbon
monoxide; can compound the effects of radon pollution
Moisture – when excessive, can lead to the overgrowth of
mold and mildew particles
Building products – i.e., carpet, paint, pressed wood
products; a major source of VOCs
Heating equipment – i.e., stoves, chimneys, furnaces,
fireplaces; a source of respirable particulates and carbon monoxide
Other sources – cleaning supplies, pesticides, new
electronics, upholstered furniture, glue, radon-contaminated soil or water
supply
Solutions
In many cases, you can reduce indoor air pollution by removing the source. Not smoking cigarettes
in the house is an obvious solution. It is also possible to test your home’s radon
and carbon monoxide levels to determine if there is a problem and eliminate it.
Excess moisture can be removed with a dehumidifier. Store toxic materials, such
as paint and pesticides, outdoors. Regular heating system maintenance
is also important for reducing emissions.
Increasing
ventilation is another essential component of controlling indoor air pollution.
Toxic gases, such as radon, carbon monoxide, and VOCs, can be vented outdoors;
make sure there is adequate ventilation when using heating equipment and
painting, and store new building products outdoors for a few days before
bringing them inside. Strategically placed fans and air conditioners, along
with open windows and doors, can be used to increase ventilation. Increasing
ventilation also helps decrease humidity.
While toxins like radon or carbon monoxide must be vented
outdoors or eliminated at the source, air treatment services can remove many airborne contaminants
that cause indoor air pollution, including respirable particles, tobacco smoke,
and others. Call 333-HELP to learn more about air treatment services to control
your indoor air pollution.
