Tālcher — Pollution Health Impact
1,644 days of CPCB data (2018–2023), translated through WHO 2021, Berkeley Earth and EPIC AQLI methods. Based on CPCB station data, 2016–present.
Odisha · Live Tālcher AQI →
Living in Tālcher is the population-level health-equivalent of smoking 3.1 cigarettes a day — roughly 1,119 cigarettes a year. On average, that chronic exposure shortens life expectancy by about 6.1 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 1,644 days of CPCB monitoring, the average adult in Tālcher has breathed air with the health-equivalent of smoking 3.1 cigarettes a day — roughly 1,119 cigarettes every year (Berkeley Earth, 2015).
The data story
EPIC's AQLI research attributes about 6.1 life-years lost per person from this chronic exposure. The WHO Air Quality Guideline was met on just 4 of 1,644 days (0.2%); 476 days (29.0%) 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 September (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 1,394 days (84.8%) above WHO IT-3 meaningfully lowers exposure — especially for pregnant residents and children under 5.
