Ammonia emissions worsening Gurugram air pollution, study finds
A Respirer Living Sciences study links ammonia emissions to increased secondary PM2.5 formation across Haryana, with Gurugram identified as a hotspot. Using data from 2024 to early 2026, the report highlights rising NH3 levels, notes Sector-51 breaches in 2025, and calls for a dedicated ammonia monitoring network in the state.
Why It Matters
Ammonia acts as a precursor to fine particulate matter that affects public health; the findings suggest policy action is needed to monitor and manage ammonia emissions alongside traditional pollutants.

Monitoring gaps highlighted by environmentalists
May 12, 2026
Environmentalists highlighted gaps in the current air quality monitoring network, noting that many stations are near industrial zones and may miss agricultural pollution affecting peri-urban areas like Gurugram.
Pilot NH3 monitoring network recommended
May 12, 2026
The study recommends setting up a pilot network of 10 ammonia sensors across Haryana (five in urban hot spots like Gurugram and five in agriculture-dominated districts such as Hisar, Sirsa, and Jind) for real-time emissions data.
Gurugram ammonia thresholds breached at multiple locations
May 12, 2026
The report notes ammonia levels breached safety thresholds at multiple Gurugram locations, with Sector-51 specifically cited for elevated concentrations in 2025.
Respirer Living Sciences study publication
May 12, 2026
Respirer Living Sciences published its study on ammonia emissions and their role in secondary PM2.5 formation in Haryana, based on data from 31 monitoring stations collected through 2024 to early 2026.
World Bank Haryana Clean Air Project funding signed (March 2026)
March 2026
Haryana secured $300 million in World Bank support for the Haryana Clean Air Project for Sustainable Development; the agreement was signed in March 2026 between the World Bank, Government of India and the Haryana government.
World Bank assessment on secondary PM2.5 (March 2026)
March 2026
A World Bank assessment cited in the report noted that nearly 30% to 40% of PM2.5 pollution in Haryana is linked to secondary particulate formation.
Sector-51 ammonia level reported (2025)
2025
Sector-51 in Gurugram recorded an annual average ammonia concentration of 138.3 µg/m³ in 2025, exceeding the national limit of 100 µg/m³.
Data collection period begins (2024)
2024
Respirer Living Sciences analysed air quality data across Haryana from 2024 through early 2026, using 31 monitoring stations to assess PM2.5, PM10 and ammonia (NH3) levels and trends.
