Health Advisory — Hisar
Poor: Breathing discomfort to most people on prolonged exposure.
Recommendation: Sensitive groups (children, elderly, people with respiratory conditions) should limit outdoor exposure.
Warning: Everyone should avoid prolonged outdoor activities. Keep windows closed and use air purifiers if available.
Health Impact — Hisar
Cigarette Equivalent: Breathing this air is equivalent to smoking 5.2 cigarettes per day (based on current PM2.5 levels).
Life Expectancy Impact: Sustained exposure at this PM2.5 level could reduce life expectancy by 0.68 years (AQLI estimate, relative to WHO guideline of 5 µg/m³).
Health Recommendations for Hisar
- General Population: Everyone should reduce prolonged outdoor exertion.
- Elderly: Avoid outdoor activities. Stay indoors.
- Children: Avoid outdoor play and exertion.

Understanding Hisar Air Quality
Hisar, one of Haryana's largest cities and a major steel pipe manufacturing centre, sits on the semi-arid plains of southern Haryana where industrial emissions intersect with some of India's worst seasonal crop residue burning. The city hosts a significant cluster of steel pipe and galvanising units, along with textile and cotton ginning mills, that create a persistent industrial emission baseline. The manufacturing process - heating steel strips, welding them into pipes, and galvanising with zinc coatings - releases metallic PM, zinc oxide fumes, and SO2 into the local airshed.
The October–January period is devastating for Hisar's air quality. The kharif paddy harvest in surrounding districts triggers massive stubble burning that sends thick smoke plumes across the region. Hisar, located downwind of Punjab's major rice-growing belt, receives this transboundary pollution on northwesterly winds, pushing PM2.5 concentrations well above 200 µg/m³ during peak burning weeks in late October–November. Simultaneous winter temperature inversions trap both regional smoke and local emissions, creating a persistent smog that can last weeks. Brick kilns in the peri-urban belt add to the emission load during their October–March operating season.
Summer months (April–June) bring relief from inversions but introduce dust storms from the Thar Desert fringe to the west. The semi-arid climate (annual rainfall ~450 mm) means limited wet deposition for most of the year. The monsoon (July–September) provides the only sustained clean window. Hisar's air quality future depends heavily on the resolution of the regional stubble burning crisis and the adoption of cleaner manufacturing technologies in the steel pipe cluster.
Primary Pollution Sources
- Vehicle exhaust
- Crop residue burning
- Road dust
- Industrial emissions (steel pipes, textiles)
- Brick kilns
- Domestic heating
Geography: Southern Haryana on semi-arid plain; steel pipe manufacturing hub, agricultural region, affected by regional stubble burning
Peak pollution months: October, November, December, January
Frequently Asked Questions — Hisar
How badly does crop stubble burning affect Hisar?
Severely. Hisar lies downwind of Punjab and northern Haryana's rice-growing belt, and during peak stubble burning in October–November, PM2.5 can spike above 300 µg/m³. Satellite fire data shows fire counts surrounding Hisar among the highest in India during this period, making stubble burning the single largest contributor to severe pollution episodes.
What industries contribute to Hisar's air pollution?
Hisar is a major steel pipe manufacturing hub - pipe welding, galvanising, and zinc coating operations emit metallic PM and SO2. Cotton ginning mills, textile units, and brick kilns in the peri-urban belt add industrial emissions. However, during October–January, regional crop residue burning overwhelms all local industrial sources.
