Bilaspur — Pollution Health Impact
1,005 days of CPCB data (2021–2024), translated through WHO 2021, Berkeley Earth and EPIC AQLI methods. Based on CPCB station data, 2016–present.
Chhattisgarh · Live Bilaspur AQI →
Living in Bilaspur is the population-level health-equivalent of smoking 1.8 cigarettes a day — roughly 673 cigarettes a year. On average, that chronic exposure shortens life expectancy by about 3.5 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
Across 1,005 days of CPCB monitoring, the average adult in Bilaspur has breathed air with the health-equivalent of smoking 1.8 cigarettes a day — roughly 673 cigarettes every year (Berkeley Earth, 2015).
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 3.5 years per resident. Of the 1,005 days on record, only 5 (0.5%) met the WHO 24-hour guideline of 15 µg/m³, while 6 days (0.6%) were above the loosest WHO Interim Target-1 (75 µg/m³).
Why this pattern
Seasonality matters: December is Bilaspur's worst month (2.3 cigs/day equivalent) and September is the best (1.5 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 475 days (47.3%) when PM2.5 sits above WHO IT-3 (37.5 µg/m³).
