1.
A manufacturing facility is assessing its environmental impact. Which approach
best represents a life-cycle perspective in environmental management?
A. Focusing only on emissions during production
B. Evaluating environmental impacts from raw material extraction to disposal
C. Measuring only waste generated at the facility
D. Analyzing only energy consumption during operations
B. Evaluating environmental impacts from raw material extraction to disposal
Rationale: A life-cycle perspective considers all stages of a product’s existence,
including extraction, production, distribution, use, and disposal. This holistic
approach prevents shifting environmental burdens from one stage to another
and is central to sustainable environmental management.
2.
Which pollutant is most associated with acid rain formation?
A. Sulfur dioxide (SO₂)
B. Carbon monoxide
,C. Methane
D. Ammonia
Rationale: Sulfur dioxide reacts in the atmosphere to form sulfuric acid, a major
component of acid rain. This leads to ecosystem damage, soil acidification, and
infrastructure corrosion.
3.
What is the primary purpose of an Environmental Impact Assessment (EIA)?
A. To eliminate all industrial pollution
B. To increase production efficiency
C. To predict and evaluate environmental consequences of proposed projects
D. To replace environmental regulations
Rationale: An EIA systematically identifies, predicts, and evaluates
environmental effects of proposed actions before decisions are made, enabling
mitigation planning and informed approvals.
4.
Which process is most effective for removing dissolved heavy metals from
wastewater?
A. Sedimentation
B. Screening
C. Aeration
D. Chemical precipitation
Rationale: Chemical precipitation converts dissolved metals into insoluble
compounds that can be separated from water, making it highly effective for
heavy metal removal.
,5.
Which greenhouse gas has the highest global warming potential per molecule?
A. Carbon dioxide
B. Nitrous oxide
C. Oxygen
D. Nitrogen
Rationale: Nitrous oxide has a significantly higher global warming potential
than CO₂ over a 100-year period, making it a potent greenhouse gas despite
lower concentrations.
6.
Which agency is primarily responsible for environmental regulation enforcement
in many countries?
A. World Bank
B. National Environmental Protection Authority
C. IMF
D. Red Cross
Rationale: National environmental agencies enforce regulations, monitor
compliance, and implement environmental laws within their jurisdictions.
7.
What is the main advantage of bioremediation?
A. It increases chemical toxicity
B. It requires high energy input
C. It uses microorganisms to degrade pollutants naturally
D. It produces hazardous sludge
, Rationale: Bioremediation uses microbes to break down contaminants into less
harmful substances, making it cost-effective and environmentally friendly.
8.
Which indicator is most commonly used to measure water pollution organic load?
A. pH
B. Turbidity
C. Dissolved oxygen
D. Biochemical Oxygen Demand (BOD)
Rationale: BOD measures oxygen required by microorganisms to decompose
organic matter, directly indicating organic pollution levels.
9.
Which practice best reduces solid waste generation at source?
A. Incineration
B. Source reduction
C. Landfilling
D. Dumping
Rationale: Source reduction minimizes waste generation at its origin by
improving processes, materials, and consumption habits.
10.
Which gas is primarily responsible for ozone layer depletion?
A. Carbon dioxide
B. Methane
C. Chlorofluorocarbons (CFCs)
D. Nitrogen
