3. •Any visible or invisible particle or
gas found in the air that is not part of
the original, normal composition.
4. Natural: forest fires, pollen, dust
storm
Unnatural: man-made; coal, wood
and other fuels used in cars,
homes, and factories for energy

6. DEFINITION
• There is a gas, liquid or particles contained in
the air so that the change and affect the life or
other materials.
• The materials are suspended in the air and a
negative impact on humans, plants and
animals.
• This is due to these materials will enter the
body through breathing and can block the
flow of oxygen into the blood vessels.
• This can cause various diseases such as
cramps, cancer, asthma, cramps, and
anemia.
Dust, smoke, mist, vapor or other substances
that can block eyesight is different form of air
pollution

10. Pollutants
Pollutants can be classified as either
primary or secondary
Primary pollutants:-Are substances
directly emitted from a process, such as
the carbon monoxide gas from a motor
vehicle exhaust or sulfur dioxide released
from factories.
11. Pollutants
Secondary pollutants:- Are not
emitted directly. Rather, they form in the air
when primary pollutants react or interact. An
important example of a secondary pollutant is
ground level ozone.
19. RADON
• Radon is a chemical element in the periodic table that
has the symbol Rn and atomic number 86.
• Noble gas that is formed by the disintegration of radium,
radon is the heaviest gases and is considered a health
hazard.
• The most stable isotope is Rn-222 which has a half life of
3.8 days and used in radiotherapy.
Radon gas can accumulate in homes and cause lung
cancer [1], causing potentially 20,000 deaths in Europe
alone each year.
20. RADON
• Radioactive gas found in soil & earth bricks that
exist in the original form of radium that is
damaged - such as the decay products of
uranium.
• Progeny, decay products @ daughtera.
• Damage lung tissue & lung cancer.
• Smokers are likely to die from this cancer.
21. Radon
• Radioactive radon-
222
• Lung cancer threat
• Occurs in certain
areas based on
geology
• Associated with
uranium and organic
material in rock.
22. ASBESTOS
• Minerals in the formation of crystals / crystal.
• Long & thin fibers.
• Divided 2: serpentine & amphibole - depending
on the crystal element.
• Individuals at risk, building maintenance,
repairs, cleaning, plumber & carpenter.
23. FOMALDEHYDE
• Chemical industry
manufacturing of building
materials
& Household products.
• Products of combustion.
• In the home-building materials
/ buildings, smoke cigarettes, a
product home.
• Fuels such as gas stoves.
• Production of examples
glue & adhesive components.
24. PLUMBUM
• Abundant in the earth's crust.
• In water, soil & plants.
• Easily obtained from the spread in the soil &
water.
• May occur during the combustion of the battery
container @ container of old paint contains lead.
• Increased burning of leaded gasoline.
26. Sulfur Dioxide
•produced when coal and fuel oil
are burned
•present in power plant exhaust
•narrows the airway, causing
wheezing and shortness of
breath, especially in those with
asthma
