Indoor Air Pollution — Prelims Strategy

Prelims Strategy

For Prelims preparation on indoor air pollution, focus on memorizing specific data points: WHO guidelines (15 μg/m³ annual PM2.5), CPCB standards (40 μg/m³ annual), PMUY coverage (95 million connections), and health statistics (607,000 annual deaths).

Create a comprehensive fact sheet covering pollutant sources, health impacts, and government schemes with exact figures and dates. Practice questions often test the distinction between indoor and outdoor pollution sources, so prepare comparative tables.

Pay special attention to scheme details - PMUY launch year (2016), target beneficiaries, and implementation challenges. Common traps include confusing WHO guidelines with national standards, mixing up health statistics, and incorrect scheme coverage figures.

Use elimination techniques by identifying obviously wrong options first - for example, statements claiming 100% adoption rates or attributing radon exposure to wrong geographical areas. Focus on recent developments like WHO guideline updates and COVID-19 impact studies, as these frequently appear in current affairs-based questions.

Create mnemonics for remembering pollutant types and health effects. Practice with previous year questions to identify recurring themes and question patterns.
