Palwal — Pollution Health Impact
1,947 days of CPCB data (2019–2024), translated through WHO 2021, Berkeley Earth and EPIC AQLI methods. Based on CPCB station data, 2016–present.
Haryana · Live Palwal AQI →
Living in Palwal is the population-level health-equivalent of smoking 2.9 cigarettes a day — roughly 1,042 cigarettes a year. On average, that chronic exposure shortens life expectancy by about 5.7 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.

- Days above WHO IT-3 (37.5 µg/m³) — pregnancy & infant risk elevated
- 1,547 (79.5%)

How Palwal compares to nearby cities
What the numbers say
Overview
Living in Palwal carries a daily PM2.5 dose that Berkeley Earth compares to 2.9 cigarettes a day. Over a year, residents absorb the equivalent of 1,042 cigarettes.
The data story
EPIC's AQLI research attributes about 5.7 life-years lost per person from this chronic exposure. The WHO Air Quality Guideline was met on just 3 of 1,947 days (0.2%); 448 days (23.0%) exceeded even the 75 µg/m³ Interim Target-1 threshold.
Why this pattern
The burden concentrates in November — when the average cigarette-equivalent climbs to 4.1/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 1,547 days (79.5%) above WHO IT-3 meaningfully lowers exposure — especially for pregnant residents and children under 5.
