Which pollutants are primarily monitored under the National Air Quality Index (AQI) in India?

Explanation

The correct answer is (B) PM2.5 and PM10 Explanation: • The AQI in India monitors 8 major pollutants: PM10, PM2.5, NO₂, SO₂, CO, O₃ (Ozone), NH₃ (Ammonia), and Pb (Lead). • PM2.5 and PM10 are particulate matters that have significant health impacts due to their ability to penetrate deep into the respiratory system. Information Booster: • AQI has six categories: Good, Satisfactory, Moderately polluted, Poor, Very Poor, and Severe. Additional Knowledge: • CO₂ (Option A): While it is a greenhouse gas, it is not usually a 'pollutant' monitored under standard AQI levels because it doesn't have immediate local toxicity compared to CO.
