Summary:
- Road dust is a major contributor to air pollution in India, accounting for up to 40% of particulate matter in some cities.
- Efforts to control road dust, such as road sweeping and water spraying, have had limited success due to the large scale of the problem and the high costs involved.
- Researchers are exploring alternative solutions, such as using chemical binders to stabilize the soil and reduce dust, and developing new road construction materials that are less prone to dust generation.
