Air Quality Today: Delhi Air Remains Hazardous, SC Demands Action

Air pollution is at its worst in three years in the Delhi NCR region. Over a week after Diwali, the air quality is only seeing a slight improvement, with major areas of Delhi still breathing 'hazardous' air.

Demanding immediate action from the Centre and Delhi government, the Supreme Court on 4 November, Monday, called the toxicity of the air a violation of people's right to life. "Can we survive in this atmosphere? This is not the way we can survive. No one is safe even inside homes; it is atrocious," a top court bench said.

Air Pollution in Other Cities

Mumbai fared better, but areas in Bengaluru, Chennai, Hyderabad and Kolkata breathe ‘unhealthy’.

Mumbai: 114 (Unhealthy for sensitive groups)

Bangalore: 156 (Unhealthy)

Chennai: 189 (Unhealthy)

Hyderabad: 160 (Unhealthy)

Kolkata: 187 (Unhealthy)

Here’s what the numbers mean. The World Health Organisation identifies pollution levels are ranging from:

  • 0 - 50: Good. Air quality is considered satisfactory, and air pollution poses little or no risk.
  • 51-100: Satisfactory. Air quality is acceptable; may be a moderate health concern for sensitive people.
  • 101-200: Moderate. Sensitive groups (with lung, heart diseases) may experience health issues.
  • 201-300: Poor. Everyone may begirn to experience health issues like respiratory problems.
  • 301-400: Very Poor. Health warnings of emergency conditions. Entire population is likely to be affected.
  • 401-500: Severe. Health alert: everyone may experience more serious health issues.
