In a recent study conducted by researchers from IIT Delhi and IIT Kanpur, it has been revealed that just five states – Uttar Pradesh, Rajasthan, Maharashtra, Karnataka, and Gujarat – contribute to a staggering 60% of India’s total dust emission, measured in terms of particulate matter PM10 and PM2.5. The study, which compiled a comprehensive “inventory” of road dust emission for the year 2022, utilized vehicle registration data from 1,352 Regional Transport Offices (RTOs).
The findings of the study indicate that the concentration of PM2.5 exceeds World Health Organization (WHO) limits in 55% of Indian states. Additionally, the study underscores the health hazards associated with dust, with non-obstructive chronic bronchitis being a prominent health concern.
The study’s outcomes shed light on the critical need for targeted interventions to address dust-related issues, especially in the identified states. As dust-induced health problems persist, authorities may consider implementing measures to curb road dust emissions and improve air quality.
