,1. Which of the following environmental contaminants is
known to cause Minamata disease?
- A) Lead
- B) Asbestos
- C) Mercury
- D) Radon
Answer: C) Mercury
Rationale: Minamata disease is a severe neurological
disorder caused by mercury poisoning.
2. The primary health effect associated with prolonged
exposure to asbestos is:
- A) Kidney disease
- B) Asbestosis
- C) Thyroid dysfunction
- D) Skin cancer
Answer: B) Asbestosis
Rationale: Asbestosis is a lung disease resulting from
the inhalation of asbestos fibers.
3. Which of the following is a primary route of human
exposure to dioxins?
- A) Inhalation of contaminated air
- B) Consumption of contaminated food
- C) Direct skin contact
- D) Drinking contaminated water
Answer: B) Consumption of contaminated food
Rationale: Dioxins primarily accumulate in the food
chain, leading to human exposure through diet.

, ### Fill-in-the-Blank Questions
4. __________ is a biological indicator that helps assess
the extent of heavy metal contamination in an environment.
Answer: Bioindicator
Rationale: Bioindicators are species or compounds that
provide information on the health of an environment and the
presence of specific contaminants.
5. The concept of __________ refers to the combined
effect of multiple environmental exposures that lead to a
greater risk of adverse health outcomes.
Answer: Synergism
Rationale: Synergism occurs when the combined effect
of multiple exposures is greater than the sum of individual
effects.
### True/False Questions
6. Persistent Organic Pollutants (POPs) tend to
bioaccumulate in the food chain, leading to higher
concentrations in top predators.
- True
- False
Answer: True
Rationale: POPs are resistant to degradation and thus
concentrate in organisms higher up in the food chain.
7. The precautionary principle suggests that action should
