INDIAN AIR 8-FOLD MORE TOXIC THAN WHO NORMS: AQLI STUDY

INDIAN AIR 8-FOLD MORE TOXIC THAN WHO NORMS: AQLI STUDY

NEWS

  • A new Air Quality Life Index (AQLI) report by the University of Chicago reveals that every Indian breathes air 8 times more toxic than the WHO’s safe air quality benchmark.
  • The annual average PM2.5 levels across India exceed WHO’s 5 μg/m³ standard, affecting all 1.4 billion citizens.
  • Even India’s “cleanest” regions surpass WHO limits; residents here could gain 9.4 months in life expectancy if standards were met.

HIGHLIGHTS

Health and Life Expectancy Impact

  • Air pollution reduces the average Indian life expectancy by 3.5 years.
  • Delhi, the most polluted region, suffers the most—residents lose 8.2 years of life expectancy.
  • Southern states like Karnataka are relatively cleaner, but lowering pollution to WHO levels could still extend lives by 1.6 years.
  • Nearly 46% of Indians live in regions exceeding India’s own weaker PM2.5 standard (40 μg/m³).

Nature of Pollution

  • PM2.5 (particulate matter <2.5 microns) is the deadliest pollutant, capable of penetrating lungs and entering the bloodstream.
  • Along with PM10, it is a key air quality indicator used to monitor dust and toxic particles.

Global and National Context

  • AQLI Director Tanushree Ganguly emphasized that air pollution is a top cause of reduced life expectancy worldwide.
  • The study uses satellite data and ground-level monitoring, reflecting India’s 2023 pollution scenario.

Implications for Policy and Governance

  • Highlights the urgent need for stricter air quality regulation, both at national and state levels.
  • Calls for alignment of India’s pollution standards with WHO norms.
  • Necessitates multi-sectoral measures—clean energy transition, reduced vehicular emissions, crop-residue management, and industrial controls.
