Chandrapur — Pollution Health Impact
1,493 days of CPCB data (2017–2022), translated through WHO 2021, Berkeley Earth and EPIC AQLI methods. Based on CPCB station data, 2016–present.
Maharashtra · Live Chandrapur AQI →
Living in Chandrapur is the population-level health-equivalent of smoking 2.4 cigarettes a day — roughly 894 cigarettes a year. On average, that chronic exposure shortens life expectancy by about 4.8 years per resident.
Cigarette-equivalence (Berkeley Earth 2015) and life-years lost (EPIC AQLI) are peer-reviewed communication heuristics, not clinical diagnoses. Full sources linked on the methodology page.

What the numbers say
Overview
Chandrapur's air pollution translates to about 2.4 passive cigarettes per resident per day. That's 894 cigarette-equivalents annually, inhaled without choice.
The data story
Using the Air Quality Life Index coefficient from EPIC at the University of Chicago, that long-run exposure reduces average life expectancy by roughly 4.8 years per resident. Of the 1,493 days on record, only 79 (5.3%) met the WHO 24-hour guideline of 15 µg/m³, while 298 days (20.0%) were above the loosest WHO Interim Target-1 (75 µg/m³).
Why this pattern
Seasonality matters: November is Chandrapur's worst month (3.5 cigs/day equivalent) and August is the best (1.2 cigs/day). Per WHO's 2024 attribution, 68% of PM2.5-attributable deaths globally come from ischaemic heart disease and stroke, 14% from COPD, 14% from acute lower-respiratory infections in children under 5, and 4% from lung cancer.
What to do with this
These numbers are communication heuristics, not a clinical diagnosis — but they make the stakes legible. Low-cost actions stack: check 24-hour PM2.5 daily, wear an N95 in winter mornings, and run a HEPA purifier indoors during peak months. Pregnant residents and children under 5 are most at risk (WHO 2024) and benefit most from clean-air interventions on the 1,028 days (68.9%) when PM2.5 sits above WHO IT-3 (37.5 µg/m³).
