7. 1.Farmers regularly used pesticides in
their farms; they considered
pesticides as what type of waste?
A. agricultural waste
B. fishery waste
C. industrial waste
D. municipal waste

8. 2. Which of these terms refer to the
unwanted substances needed to
disposed?
A. compost
B. plastic
C. solid waste
D. waste

9. 3. In times of Covid-19 pandemic,
many people used facemasks to
protect themselves. As a responsible
citizen, disposable facemasks should
be put in a ___________________
container.
A. hazardous waste
B. liquid waste
C. organic waste
D. solid waste

10. 4. Which is the appropriate definition of
hazardous waste?
A. Only liquid wastes that is considered
toxic and chemically reactive
B. Only solid waste that is considered toxic
and chemically reactive
C. Any solid, liquid or gaseous waste that
is considered toxic and chemically reactive
D. Only gaseous waste that is considered
toxic and chemically reactive

11. 5. Jose is an advocate of proper waste
disposal and encourages other students to
practice recycling. Will you help Jose
identify which of the following items can be
recycled?
A. aluminum cans
B. card boards
C. paper cups
D. All of the above

13. Thermal treatment is a process by
which heat is applied to the waste to
sanitize it. The primary function of
thermal treatment is to convert the
waste to a stable and usable end
product and reduce the amount that
requires final disposal in landfills.

14. A.Incineration
B.Gasification and
pyrolysis
C.Open burning

15. This approach involves the

Theadvantagesofthisapproachare:
quickly reduced waste volume,
lessenstransportation costs,and
decreases harmfulgreenhouse gas
emissions.

16. both of which decompose organic waste
materials by exposing waste to low
amounts of oxygen and very high
temperature.
Pyrolysis uses no oxygen while
gasification allows a very low amount of
oxygen in the process.
Gasification is more advantageous as it
allows the burning process to recover
energy without causing air pollution.

18. A dumpis an excavated piece
of land used as storage for
waste materials while a landfill
is also an excavated piece of
land for waste storage but it is
regulated by the government.

20. 1.Sanitary landfills
2.Controlled dumps
3.Bioreactor landfills

22. -also known as the conventional
method, is a common and widely used
method of treatment. It takes into
account biodegradation bleaching by
taking aid of several micro-organisms,
fungi, bacteria, yeasts, and algae. This
is a cheap and easy process that goes
through a combination of aerobic and
anaerobic processes.

23. 1.Composting
2.Anaerobic digestion

25. 1.Exposures occur through:
a. Ingestion of contaminated water or food
b. Contact with disease vectors
c. Inhalation
d. Dermal
2. Points of contact, soil adsorption,
storage, and biodegrading
3. Plant uptake
4. Ventilation

26. 5. Runoff
6. Leaching
7. Insects, birds, rats, flies, and
animals
8. Direct dumping of untreated
waste in seas, rivers, and lakes
results in the plants and animals
that feed on it

27. 1.Chemical poisoning through chemical
inhalation
2.Low birth weight
3.Congenital malformations
4.Neurological disease and cancer
5.Nausea and vomiting
6.Increase in the hospitalization of
diabetic residents living near
hazardous waste sites
7.Mercury toxicity from eating fish with
high levels of mercury

28. 1.Increase in mercury level in fish
due to disposal of mercury in the
rivers
2.Plastic found in oceans ingested
by birds
3.Resulted in a high algal
population in rivers and sea
4.Degrades water and soil quality

29. 1.Waste breaks down in landfills to form
methane, a potent greenhouse gas
2.Change in climate and destruction of
the ozone layer due to waste
biodegradable
3.Littering, due to waste pollutions,
illegal dumping
4.Leaching is a process by which solid
waste enters soil or groundwater and
contaminates them

30. 1.Soil contamination
2.Air contamination
3.Water contamination
4.Bad impact on human health
5.Impact on animals and marine life
6.Disease-carrying pests
7.Adversely affect the local economy
8.Missed recycling opportunities
9.Causes extreme climate change
