Title: INDOOR AIR POLLUTION


1
INDOOR AIR POLLUTION
At risk a.       smokers b.      infants and
children lt 5 c.       old, sick and
pregnant d.      those with respiratory/ heart
problems e.       factory workers  
2
SICK BUILDING SYNDROME
Sick Building Syndrome is a condition where a
person experiences fatigue, headaches, dizziness,
nausea, and flu-like symptoms due to poor indoor
air quality. Causes cigarette smoke 2.     
formaldehyde 3.      Asbestos 4.     
Radon-222  Indoor air pollutants are spread
throughout a building through air ventilation
systems and ceiling fibers.

CIGARETTE SMOKE
1.Cigarette Smoke (first hand or second hand)
CO gas from smoking reacts with hemoglobin in RBC
and decreases oxygen in the blood stream. This
results in impaired perception and thinking,
slower reflexes, headaches, drowsiness,
dizziness, and nausea. People who have heart
disease are at risk of having heart attacks.
People with respiratory sensitivity or disease
can experience bronchitis, emphysema, and anemia.
4
FORMALDEHYDE
  • Formaldehyde emitted from common building
    materials. Formaldehyde exposure has caused
    cancer in laboratory rats. Can also cause
    dizziness, nausea and headaches.

5
ASBESTOS
  • Asbestos A silicate mineral (amphibole) used in
    building materials for fireproofing. ONLY
    dangerous when it is airborne. The asbestos
    shard-like fibers cause lung cancer and
    mesothelioma (cancer in the lining of the chest
    cavity).

6
ASBESTOS
  • -         Between 1900-1984 asbestos was sprayed
    on ceilings and walls of schools and other public
    and private buildings for fireproofing,
    soundproofing, insulation of heaters and pipes,
    and for wall and ceiling decorations.
  • -         EPA banned asbestos in 1984.
  • -         1991 The Appellate court overturned the
    89 EPA ban and Canada and the USA are still
    producing products made of asbestos! BIG
    BUSINESS!!
  • -         In public buildings such as schools it
    is better to seal the asbestos than to remove it.
    Once it is disturbed, it becomes airborne.

7
ASBESTOS
  • 1998 Chemist invented a foam (sealant) that
    initiates a chemical reaction that binds the
    asbestos minerals together to form a hard,
    nontoxic material that acts as a fireproofing
    material.

RADON-222 GAS
  • Radon-222 Gas (odorless, tasteless, colorless).
    It is a product from the radioactive decay of
    uranium 238 which is present in granite and shale
    bedrock.

11
RADON-222-GAS
  • -         Harmless when it seeps upward through
    the soil to the atmosphere and dissipates.
  • -         Harmful when it seeps upward through
    the soil into basements through foundation cracks
    or into the groundwater. It can build to
    dangerous levels, cling to particles and become
    lodged in lung tissue.
  • -         If inhales, lung tissue is exposed to
    ionizing radiation from alpha particles and may
    produce lung cancer.
  • -         To test for radon-222 purchase a
    home-testing kit for 20-100 dollars.
  • -         New Jersey high area for Radon-222
    due to much bedrock of granite and shale.
  • -         Long Island no bedrock no radon-222!

RADON TESTING

How Can We Reduce Indoor Air Pollution?
  • Ban smoking in public places ongoing
  • Cover ceiling tiles and AC ducts
  • stricter formaldehyde emission standards for
    furniture and building materials
  • prevent radon-222 infiltration by better
    construction and planning techniques
  • use office machines in well ventilated areas
  • use less harmful substances such as paints,
    varnishes and cleaners).

14
How Can Laws Be Improved? 
  • Pollution prevention is best!
  • Increase fuel efficiency standards for indoor
    equipment.
  • Campaign Finance Reform!
