Environmental Management and Sustainable Development flashcards for GATE Environmental Engineering

19 of 51 cards from the Environmental Management and Sustainable Development deck — real questions with worked answers.

1. What is the ISO 14000 series?

   A family of international standards developed by the International Organization for Standardization (ISO) that provide a framework for organizations to manage their Environmental Management Systems (EMS) and minimize harmful effects on the environment.

2. Which standard in the ISO 14000 series specifies the requirements for an Environmental Management System (EMS)?

   ISO 14001 — it is the only certifiable standard in the series and specifies requirements for establishing, implementing, maintaining, and improving an EMS.

3. What management cycle forms the backbone of ISO 14001 EMS?

   The Plan-Do-Check-Act (PDCA) cycle: Plan (set objectives), Do (implement processes), Check (monitor and measure), Act (take corrective action for continual improvement).

4. What do ISO 14040 and ISO 14044 standards address?

   They provide the principles, framework, requirements, and guidelines for conducting a Life Cycle Assessment (LCA).

5. Define environmental auditing.

   A systematic, documented, periodic, and objective evaluation of how well an organization, its management, and equipment are performing in conserving the environment and complying with environmental regulations.

6. What are the main types of environmental audits based on who conducts them?

   First-party (internal/self audit), second-party (supplier audit by a customer), and third-party (independent external audit, e.g., for ISO 14001 certification).

7. What is Life Cycle Assessment (LCA)?

   A 'cradle-to-grave' technique to assess the environmental impacts associated with all stages of a product's life — raw material extraction, manufacturing, distribution, use, and disposal/recycling.

8. What are the four phases of an LCA according to ISO 14040?

   (1) Goal and scope definition, (2) Life Cycle Inventory analysis (LCI), (3) Life Cycle Impact Assessment (LCIA), and (4) Interpretation.

9. What is the difference between 'cradle-to-grave' and 'cradle-to-cradle' in LCA?

   Cradle-to-grave covers extraction through final disposal; cradle-to-cradle treats end-of-life materials as input for new products through recycling, creating a closed loop with no final disposal.

10. What is Human Health Risk Assessment?

    A process to estimate the nature and probability of adverse health effects in humans exposed to chemicals in contaminated environmental media, now or in the future.

11. What are the four steps of Human Health Risk Assessment (US EPA framework)?

    (1) Hazard identification, (2) Dose-response assessment, (3) Exposure assessment, and (4) Risk characterization.

12. How is Chronic Daily Intake (CDI) used to estimate carcinogenic risk?

    Carcinogenic risk is estimated as $\text{Risk} = CDI \times SF$, where $CDI$ is the chronic daily intake (mg/kg-day) and $SF$ is the cancer slope factor (per mg/kg-day).

13. How is the Hazard Quotient (HQ) for non-carcinogenic risk calculated?

    $HQ = \dfrac{CDI}{RfD}$, where $CDI$ is the chronic daily intake and $RfD$ is the reference dose. An $HQ > 1$ indicates potential for adverse non-cancer health effects.

14. What is the Reference Dose (RfD) in risk assessment?

    An estimate of the daily oral exposure (mg/kg-day) to a non-carcinogenic substance that is likely to be without an appreciable risk of harmful effects over a lifetime.

15. What acceptable carcinogenic risk range is generally used by regulatory agencies?

    An incremental lifetime cancer risk between $10^{-6}$ (one in a million) and $10^{-4}$ (one in ten thousand) is typically considered acceptable.

16. State the Polluter Pays Principle (PPP).

    The principle that the party responsible for producing pollution should bear the costs of managing it and remedying the damage caused to human health and the environment.

17. By which body and document was the Polluter Pays Principle first formally articulated internationally?

    By the OECD (Organisation for Economic Co-operation and Development) in 1972 as a guiding principle for the allocation of pollution-control costs.

18. State the Precautionary Principle.

    Where there are threats of serious or irreversible environmental damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.

19. In which 1992 declaration are the Precautionary Principle and Polluter Pays Principle codified?

    The Rio Declaration on Environment and Development (1992) — Principle 15 (Precautionary) and Principle 16 (Polluter Pays).
