Q6. Explain the concept of oxidative potential in relation to PM2.5. Discuss how this understanding can improve urban preparedness in polluted Indian cities. (10 M)
Difficulty Level: Difficult
Reference: DTE
Why the question: Recent studies like the 2024 Bose Institute research in Kolkata show that oxidative potential (OP) of PM2.5 is a stronger predictor of health risks than mere concentration levels, prompting a shift in how air pollution should be assessed and tackled. Key Demand of the question: The answer must explain the concept of oxidative potential as a metric of PM2.5 toxicity and evaluate how this scientific understanding can shape India’s public health readiness and urban planning strategies. Structure of the Answer: Introduction: Briefly define oxidative potential and link it to PM2.5 toxicity and air pollution’s health impact. Body: Explain how OP is measured and what it reveals about particulate matter. Discuss how OP-informed data can improve risk-based air quality monitoring and enable targeted urban interventions. Conclusion: Emphasise the need to move beyond traditional air quality indices towards health-sensitive metrics like OP for better urban resilience.
