Rourkela — Pollution Health Impact
395 days of CPCB data (2022–2024), translated through WHO 2021, Berkeley Earth and EPIC AQLI methods. Based on CPCB station data, 2016–present.
Odisha · Live Rourkela AQI →
Living in Rourkela is the population-level health-equivalent of smoking 3.2 cigarettes a day — roughly 1,159 cigarettes a year. On average, that chronic exposure shortens life expectancy by about 6.4 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.

How Rourkela compares to nearby cities
What the numbers say
Overview
Rourkela's air pollution translates to about 3.2 passive cigarettes per resident per day. That's 1,159 cigarette-equivalents annually, inhaled without choice.
The data story
EPIC's AQLI research attributes about 6.4 life-years lost per person from this chronic exposure. The WHO Air Quality Guideline was met on just 0 of 395 days (0.0%); 162 days (41.0%) exceeded even the 75 µg/m³ Interim Target-1 threshold.
Why this pattern
The burden concentrates in December — when the average cigarette-equivalent climbs to 4.2/day — and eases in August (1.7/day). Globally, WHO attributes 68% of PM2.5 deaths to heart disease and stroke, with the remainder split across COPD, childhood ALRI, and lung cancer.
What to do with this
Cigarette-equivalence is a communication tool, not a medical verdict. Still, the direction is clear: time indoors with a HEPA unit and a good-fit mask outdoors during the 347 days (87.8%) above WHO IT-3 meaningfully lowers exposure — especially for pregnant residents and children under 5.
