1. The primary goal of environmental management systems (EMS) is to
A. Increase production efficiency
B. Minimize environmental impacts and ensure compliance
C. Eliminate all waste
D. Replace regulatory agencies
Rationale: An EMS provides a structured framework to control, reduce,
and continually improve environmental performance while meeting legal
requirements.
2. Which international standard specifies requirements for an environmental
management system?
A. ISO 9001
B. ISO 14001
C. ISO 45001
D. ISO 26000
Rationale: ISO 14001 is the globally recognized standard for
environmental management systems.
3. An environmental aspect is best defined as
A. Any environmental law
, B. A pollution control device
C. An element of activities that can interact with the environment
D. An environmental impact
Rationale: Aspects are causes, while impacts are the changes to the
environment resulting from those aspects.
4. The Clean Air Act primarily regulates
A. Solid waste disposal
B. Air pollutant emissions
C. Drinking water quality
D. Hazardous waste transport
Rationale: The Clean Air Act establishes standards for air emissions from
stationary and mobile sources.
5. Which pollutant is most associated with acid rain?
A. Carbon monoxide
B. Sulfur dioxide
C. Methane
D. Ozone
Rationale: Sulfur dioxide and nitrogen oxides react in the atmosphere to
form acids that cause acid rain.
6. Environmental impact assessments (EIA) are conducted to
A. Increase construction speed
B. Replace permits
C. Identify and mitigate potential environmental effects
D. Reduce project costs only
Rationale: EIAs evaluate potential environmental consequences before
project approval.
7. Which U.S. law governs hazardous waste from cradle to grave?
A. CERCLA
B. RCRA
C. TSCA
D. NEPA
, Rationale: RCRA establishes a comprehensive system for managing
hazardous waste throughout its lifecycle.
8. The primary objective of NEPA is to
A. Regulate emissions
B. Ensure informed decision-making through environmental review
C. Enforce penalties
D. Set exposure limits
Rationale: NEPA requires federal agencies to consider environmental
impacts before taking major actions.
9. Which term describes the maximum concentration of a contaminant
allowed in drinking water?
A. TLV
B. MCL
C. PEL
D. REL
Rationale: Maximum Contaminant Levels (MCLs) are enforceable drinking
water standards.
10.Sustainability is best described as
A. Economic growth only
B. Environmental protection only
C. Meeting present needs without compromising future generations
D. Recycling programs
Rationale: Sustainability balances environmental, social, and economic
considerations.
11.The main purpose of pollution prevention is to
A. Treat waste after generation
B. Reduce waste at the source
C. Increase disposal capacity
D. Dilute pollutants
Rationale: Pollution prevention focuses on eliminating or reducing waste
before it is created.
