Delhi's NO₂ Levels Soar to 7-Year High, Posing Severe Health Risks

• Delhi's Nitrogen Dioxide (NO₂) levels reached 47 µg/m³ in 2025, the highest in seven years, significantly exceeding WHO's 10 µg/m³ safety limit and India's 40 µg/m³ standard.
• Vehicular emissions are the primary cause, alongside industrial activities and power plants, contributing to the rise in NO₂.
• High NO₂ levels lead to severe respiratory issues, lung inflammation, increased asthma severity, and contribute to other dangerous pollutants like PM2.5 and ground-level ozone.
• Winter weather exacerbates the problem by trapping the gas closer to the ground, intensifying pollution.
• While GRAP-4 restrictions are lifted, GRAP 1, 2, and 3 remain, and Delhi's AQI is still in the 'Severe' category, indicating ongoing danger.

Why It Matters: Delhi faces a critical health threat as NO₂ pollution hits a 7-year peak, far exceeding safety norms.
