India's Silent Killer: Construction Dust Chokes Cities
8 Mar
Summary
- Construction dust is a persistent, year-round air pollution source in India.
- PM2.5 from dust penetrates lungs, raising risks of heart disease and cancer.
- Effective dust mitigation requires consistent enforcement, not just bans.
India's unprecedented scale of construction, marked by highways, metros, and rising towers, is also a significant contributor to pervasive air pollution. Beyond seasonal crises like crop burning, construction and road dust represent a structural, year-round source of harmful PM2.5 and PM10 particles.
These fine particles penetrate deep into the lungs and bloodstream, elevating risks for heart disease, stroke, lung cancer, and premature death. While public attention often focuses on vehicles and crop burning, multiple studies show construction and road dust contribute substantially to particulate pollution in Indian cities.
