Our Lungs
Our lungs
are directly
connected
to the
environment
.
People breath continuously (Breathing is NOT optional)
Oxygen & carbon-dioxide pass through very thin walls of alveoli
But, any gas (poisonous ones, too) can pass through alveoli walls
And, very small particles can also pass through alveoli walls
nau.edu/iaqtc
What are common symptoms
indicating IAQ issues in schools?
 Eye, nose, and throat irritation
 Coughing, sneezing, and wheezing
 Asthma attacks
 Headaches
 Fatigue
 Aggravated allergies and asthma
 Respiratory infections

What are common concerns in
tribal schools?
 Many older buildings don’t have active ventilation
 Schools with HVAC may reduce fresh air intake to

What are pollutant sources
in tribal schools?
 People - everyone is a source of pollutants

2. Assess:
Do initial school walk-through
Listen to occupants
3. Plan:
Prioritize actions
Develop goals
nau.edu/iaqtc
4. Act:
Education of occupants
5. Evaluate:
Measure impacts
Return on Investment (ROI)
6. Communicate:
Transparent
Share results

Asthma
 Many potential triggers are air pollutants
 Inflammation of airways
 Blocking, narrowing airways, mucous
nau.edu/iaqtc
What causes asthma?
 Research into the causes of asthma is still ongoing.
 Strong links to family medical history.
 Strong links to exposure to tobacco smoke.
 Many other connections under investigation.

What is Asthma?
Asthma is a condition that:
• is chronic
• produces recurring episodes
•
•
•
•
of breathing problems
is potentially life-threatening
can start at any age
is not contagious
cannot be cured, but can be
controlled
nau.edu/iaqtc
What makes Asthma Worse?
• Not all factors affect all people.
• It is important to identify what affects a particular person’s
asthma.
Exercise: Exercise Induced Asthma
Infections in the upper airways, such
as colds
Changes in weather and temperature
Physical expressions of strong
feelings such as crying, laughing
hard, yelling
nau.edu/iaqtc
What makes Asthma Worse?
Allergens such as:
• Dust mites
• Cockroaches
• Furred and feathered
animals
• Pollens (grass and trees)
• Molds (indoor and outdoors)
• Nitrogen dioxide
nau.edu/iaqtc
www.cliver.com
What makes Asthma Worse?
Irritants such as:
• Environmental tobacco smoke
• Air pollution including wood smoke
• Scented products
• Strong fumes or odors
nau.edu/iaqtc
What can I do to help?
 Limit the amount of perfumed products you wear.
 Be conscious of exposure to certain cleaning products
and use less toxic alternatives when possible.
 Choose not to smoke around others, especially children.
 Improve air quality in schools and community
 Learn more about asthma prevention
 Teach others about asthma prevention

Radon
 Radioactive gas
 Radon in air is ubiquitous
 Found in outdoor air and indoor air of
buildings of all kinds
 No known safe level of radon
www.radonleaders.org
www.nau.edu/eeop
Radon “Daughters”
Radon, Polonium, Lead,
Bismuth, and Polonium
have short half-lives
Results in several
exposures in a
short time
www.nau.edu/eeop
Radon in Lungs
 Radon or decay
products inhaled
 Particles irradiate
lungs
Radon
 Irradiation can cause
www.nau.edu/eeop
lung cancer
What health issues are
associated with Radon?
 Radon is number one cause of lung
cancer among non-smokers
 Second leading cause of lung cancer
 Responsible for about 21,000 lung
cancer deaths every year
 About 2,900 lung cancer deaths are
among people who have never
smoked
www.epa.gov
www.nau.edu/eeop
Radon – EPA Action Levels
 Red alert - radon level above 4 pCi/L (pico Curies per Liter)
 Yellow alert - radon levels between 2 pCi/L and 4 pCi/L
 Average radon indoor air about 1.3 pCi/L
www.nau.edu/eeop
Where is Radon found?
 Comes from soil
 Lower parts of building
at greatest risk
 “Stack effect” pulls
Radon into home
 Found in all 50 states
 Found in about 1 out of
15 homes

www.nau.edu/eeop
Radon Test Kits
 Tribal Offices can order test kits at nau.edu/iaqtc
 Individuals can purchase test kits
 online at www.epa.gov/radon/radontest.html

Mold
nau.edu/iaqtc
Mold
 Molds live in the soil,
on plants, on dead or
decaying organic
matter
 Outdoors - breaks
down leaves, wood,
plant debris
 Indoors - air pollution
and destroys buildings
nau.edu/iaqtc
Mold Basics - Health
 People have lots of
different reactions to
mold
 Symptoms can include
allergic reactions,
asthma, and other
respiratory complaints
 Molds can be found
almost anywhere
nau.edu/iaqtc
Mold Basics – Controlling
 Control indoor mold growth by controlling moisture
 Fix the water problem or leak to prevent mold growth
 Control Indoor Humidity (30% to 60%)
 Vent showers and other moisture sources to the
outside
 Use air conditioners and de-humidifiers as needed
 Provide adequate ventilation
 Use exhaust fans in food service areas
nau.edu/iaqtc
Mold Basics – Controlling
 Reduce the potential for
condensation on cold
surfaces by adding
insulation
 Do not install carpeting
by drinking fountains, by
classroom sinks, or on
concrete floors
nau.edu/iaqtc
Mold Basics - Cleaning
 Mold growth begins within 24-48 hours of getting wet
 Clean up the mold and eliminate
sources of moisture
 Clean mold off hard surfaces with
water and detergent, and dry
completely
 Absorbent materials such as
ceiling tiles may need to be
replaced
• Protect staff and building occupants during cleanup
