APES 2013- 2014 INDOOR AIR POLLUTION NOTES
Slide 2
INDOOR AIR POLLUTION The quality of indoor air can be two to
five times (and even up to 100 times) more polluted than the worst
outside air.
Slide 3
Slide 4
Common symptoms of exposure to indoor air pollutants include
headaches, tiredness, dizziness, nausea, itchy nose, and scratchy
throat. More serious effects are asthma and other breathing
disorders and cancer.
Slide 5
SOURCES OF INDOOR AIR POLLUTANTS
Slide 6
COMBUSTION SOURCES: GAS, OIL, KEROSENE AND WOOD STOVES OR
FIREPLACES, TOBACCO SMOKE
Slide 7
BUILDING MATERIALS: INSULATION, CARPET, CABINETRY, PRESSED WOOD
PRODUCTS
Slide 8
CHEMICAL PRODUCTS: CLEANING PRODUCTS, PERSONAL CARE PRODUCTS,
GLUES, PASTES
Slide 9
OUTDOOR SOURCES: RADON, PESTICIDES, POLLEN, OUTDOOR AIR
POLLUTION

RADON GAS Can seep into buildings from the soil
Naturally-occurring radioactive gas that is a product of the
radioactive decay chain from uranium to stable lead.

A variety of methods have been employed to keep the hot or cool
air from escaping from our homes installing storm windows and
insulation applying caulk and weather-stripping to seal cracks and
other openings heating our homes with kerosene, wood, coal, and
natural gas. Unfortunately, when we trap in hot or cool air, we
also trap in pollutants and sometimes generate more. OVER THE
YEARS, BUILDINGS HAVE BEEN MADE MORE AIRTIGHT TO CONSERVE
ENERGY.

Testing indoor air is not practical or affordable unless a
specific pollutant (ex. radon) is suspected. It is much more
efficient to examine the home and review activities, furnishings,
conditions, and recent changes to develop a list of likely
pollutants. IMPROVING INDOOR AIR QUALITY
Slide 20
The three most important methods of improving indoor air
quality are source removal (cleaning floor, using a dehumidifier,
cutting down on synthetic fragrances, having hard floors instead of
carpet, no candles/fireplaces) air cleaning (keeping indoor
plantsex. Devils Ivy and Peace Lily, using an air purifier,
checking and replacing air filters) increased ventilation (opening
windows).

Slide 22
EXPOSURE FACTS Around 3 billion people cook and heat their
homes using open fires and leaky stoves burning biomass (wood,
animal dung and crop waste) and coal. Nearly 2 million people die
prematurely from illness attributable to indoor air pollution from
household solid fuel use.
Slide 23
Slide 24
More than 1 million people a year die from chronic obstructive
respiratory disease (COPD) that develops due to exposure to indoor
air pollution. Both women and men exposed to heavy indoor smoke are
2-3 times more likely to develop COPD.
