2. •Last august 23, 2011,
Philippines was hit by
typhoon Nanmadol or
Mina
•Typhoon Mina was
the strongest tropical
cyclone in 2011 to hit
the Philippines
3. •On August 27, the
typhoon brought
relentless rains to
the archipelago
causing the
retaining wall
of Baguio's dump
facility to collapse
(Irisan dumpsite)
4.
5. •The Office of Civil Defense reported 10
persons dead, 12 injured and five other
missing
•Six of the fatalities died in Baguo City.
Five perished when the retaining wall of
the Irisan dumpsite collapsed Saturday
during the height of typhoon Mina
•Three houses were buried

7. Rescuers look for victims buried in a dumpsite collapse in Baguio City
as steady rains from typhoon Mina pounded North Luzon
8. Some Danger Brought by Garbage
Landslide:
Exposure to methane
Hydrogen sulfide
Airborne biological contaminants

15. Concentratio
n
(ppm)
Symptoms/Effects
0.00011-
0.00033
Typical background concentrations
0.01-1.5 Odor threshold (when rotten egg smell is first noticeable
to some). Odor becomes more offensive at 3-5 ppm.
Above 30 ppm, odor described as sweet or sickeningly
sweet.
2-5 Prolonged exposure may cause nausea, tearing of the
eyes, headaches or loss of sleep. Airway problems
(bronchial constriction) in some asthma patients.
20 Possible fatigue, loss of appetite, headache, irritability,
poor memory, dizziness.
50-100 Slight conjunctivitis ("gas eye") and respiratory tract
irritation after 1 hour. May cause digestive upset and loss
Short Term Symptoms:
16. 100 Coughing, eye irritation, loss of smell after 2-15 minutes
(olfactory fatigue). Altered breathing, drowsiness after 15-
30 minutes. Throat irritation after 1 hour. Gradual
increase in severity of symptoms over several hours.
Death may occur after 48 hours.
100-150 Loss of smell (olfactory fatigue or paralysis).
200-300 Marked conjunctivitis and respiratory tract irritation after 1
hour. Pulmonary edema may occur from prolonged
exposure.
500-700 Staggering, collapse in 5 minutes. Serious damage to the
eyes in 30 minutes. Death after 30-60 minutes.
700-1000 Rapid unconsciousness, "knockdown" or immediate
collapse within 1 to 2 breaths, breathing stops, death
within minutes.
1000-2000 Nearly instant death
17. Long Term Health Effects:
•knockdown (rapid unconsciousness)
•continue to have headaches
• poor attention span, memory, and motor
function after waking up
•Problems with the cardiovascular system
•People who have asthma may be more
sensitive to hydrogen sulfide exposure.

19. Biological
Contaminants are living
organisms (such
as bacteria, enzymes,
fungi, viruses) or
their products that can
be hazardous to animal
or human health if
inhaled, swallowed, or
otherwise absorbed into
the body.
20. The protein in urine
from rats and mice is
a potent allergen.
When it dries, it can
become airborne
21. LEPTOSPIROSIS
-transmitted to
humans by allowing
water that has been
contaminated by animal
urine to come in contact
with unhealed breaks in
the skin, the eyes, or
with the mucous
membranes.
23. Malaria- a disease
spread by
mosquitoes. It is
caused by the
protozoa
Plasmodium. This is
a very common
disease in places
where mosquitoes
breed very quickly.
24. Typhoid- a
waterborne disease.
People who
drink polluted water
can become infected
with typhoid. The
garbage in the area is
a good breeding
ground for flies. The
flies can then carry
the disease and infect
more people.
25. Dysentery- a disease
that can cause severe
diarrhea. If not treated
properly, someone can
die from it. This is a
waterborne illness that
is transmitted to a
person when they
drink the polluted
water.
26. Cholera- a disease
that causes diarrhea.
Cholera is a
waterborne disease
that can be
dangerous to
everyone that lives in
an unsanitized
environment.
27.
28. Drainage system must be ensured to
catch run off water
Building of houses should be
regulated and based on the
characteristic of the location
Habitation of the area should be
disallowed
Dumpsite was converted to eco-park
Notas del editor
Methane is produced because dumps are anaerobic – there is no air getting into them down below. methane can explode and/or burn
Methane is combustible, and mixtures of about 5 to 15 percent in air are explosive. Methane is not toxic when inhaled, but it can produce suffocation by reducing the concentration of oxygen inhaled.
Asphyxia or asphyxiation (from Greek α- "without" and σφύξις sphyxis, "heartbeat") is a condition of severely deficient supply of oxygen to the body that arises from being unable to breathe normally.
Hydrogen sulfide gas is also known as “sewer gas” because it is often produced by the breakdown of waste material.bacterial breakdown of organic matter and be produced by human and animal wastes.
Hydrogen sulfide is considered a broad-spectrum poison, meaning that it can poison several different systems in the body, although thenervous system is most affected. The toxicity of H2S is comparable with that of hydrogen cyanide or carbon monoxide.
