This document discusses air pollution. It begins by defining air pollution and listing common sources such as vehicles, industry, and fires. It then outlines several health problems caused by air pollution, including heart disease, cancer, and respiratory diseases. It explains how different types of pollutants like particulate matter can cause these issues. The document also distinguishes between primary and secondary pollutants. Laws and acts passed to control air pollution, such as the Clean Air Act and Philippine Clean Air Act, are mentioned. Finally, the formation and risks of temperature inversions are briefly explained.

What is…

19. WHAT IS AIR POLLUTION?
•Air pollution is contamination of the indoor or
outdoor environment by any chemical, physical or
biological agent that modifies the natural
characteristics of the atmosphere. Household
combustion devices, motor vehicles, industrial
facilities and forest fires are common sources of air
pollution.

21. DISEASES CAUSED BY AIR POLLUTION
•strokes, asthma, bronchitis, lung disease,
obstructive pulmonary disease, and premature
death from heart ailments. Higher Particulate
matter exposure also results in impairing brain
development in children

22. CANCER CAUSED BY AIR POLLUTION
• There are a few different ways that particles in air pollution
could damage DNA in cells and cause lung cancer. For
example, tiny particles may build up in the lungs and
change how cells replicate. This could lead to DNA damage
which can cause cancer.
• It's no surprise that air pollution has been linked with lung
cancer. A new study suggests that pollution is also
associated with increased risk of mortality for several other
types of cancer, including breast, liver, and pancreatic
cancer.

23. HEART DISEASE CAUSED BY
AIR POLLUTION
•Study found out that long-term exposure to
particulate matter and nitrogen oxides at levels
close to the National Ambient Air Quality Standards
(NAAQS) can prematurely age blood vessels and
contribute to a more rapid buildup of calcium in
the coronary artery.

25. Pollutants
Primary Pollutants Secondary Pollutants
• pollutants that go directly into the
environment
• Secondary pollutants are pollutants which form in
the atmosphere. These pollutants are not emitted
directly from a source (like vehicles or power plants).
Instead, they form as a result of the pollutants
emitted from these sources reacting with molecules
in the atmosphere to form a new pollutant
 Volatile Organic Compounds
(VOCs)
 Lead
 Carbon monoxide
 Particulate Matters (PM or also
called as particle pollution)
 Sulfur dioxide (SO2)  Sulfoxylic acid (H2SO2)
 Nitrogen Oxide (NOx)  Nitric Acid (NHO3)
Acid Rain

27. Effects of Acid Rain

28. PRIMARY POLLUTANTS

29. VOLATILE ORGANIC COMPOUNDS
(VOCS)
• are organic chemicals that have a high vapor pressure at
room temperature.
• High vapor pressure correlates with a low boiling point,
which relates to the number of the sample's molecules in
the surrounding air, a trait known as volatility.
• A good example of this is our gasoline evaporating in our
environment. VOCs greatly influence the haziness of
Smog;

30. CARBON MONOXIDE
• is produced naturally through photochemical sources. But
it can also be produced through combustion usually done
by burning fossil fuels, plastics, and dried leaves;

31. NITROGEN OXIDE (NOX)
• is a brownish gas pollutant emitted by automobiles,
trucks, and various non-road vehicles as well as industrial
sources such as power plants, industrial boilers, cement
kilns, and turbines.

32. SULFUR DIOXIDE (SO2)
• is a colorless, reactive air pollutant with a strong odor. The
main sources of sulfur dioxide emissions are from fossil
fuel combustion and natural volcanic activity;

33. PARTICULATE MATTERS
• (PM or also called as particle pollution)
• the term for a mixture of solid particles and liquid
droplets found in the air. Some particles, such as dust,
dirt, soot, or smoke, are large or dark enough to be seen
with the naked eye. Hair is going to be on the order of
50-70 microns.

34. Comparing that to hair, we
are talking here about
things that are smaller than
that. Small sediments that
as you breathe it in the
hairs in your nose and
respiratory tract do not
trap it. It goes into your
lungs, and just like
smoking, it is stuck there
and can lead to other types
of diseases.

35. Particles less than 10
micrometers in diameter pose
the greatest problems because
they can get deep into your
lungs, and some may get into
your bloodstream. Fine
particles (PM 2.5) are the main
cause of reduced visibility
(haze) in parts of Baguio City,
including many of our national
parks and wilderness areas.

38. The warmer air in a
temperature inversion acts
as a lid, trapping pollutants
near the ground and
making them unable to
disperse until the weather
changes. As a result, the
compounds end up
reacting with each other to
form other pollutants such
as ground-level ozone, thus
posing a serious risk to
human health.

39. CONTROLS OF AIR
POLLUTION

40. THE CLEAN AIR ACT
• The Clean Air Act (CAA) is the comprehensive federal law
that regulates air emissions from stationary and mobile
sources. Among other things, this law authorizes EPA to
establish National Ambient Air Quality Standards
(NAAQS) to protect public health and public welfare and
to regulate emissions of hazardous air pollutants.

41. PHILIPPINE CLEAN AIR ACT OF 1999
- RA. 8749.
• The Act provides for the creation of a national program of
air pollution management focusing primarily on pollution
prevention; for the promotion of mass media
communication in order to create social awareness and
active participation in air quality planning and monitoring.
