Smog towers, cloud seeding not solution to India's air pollution problem: US scientist

Improving air quality in India requires long-term effort, a senior US scientist has said and noted cost-intensive technologies such as smog towers and cloud seeding are not sustainable solutions to the pollution problem plaguing the country.

In an interview with PTI, Richard Peltier, a member of the World Health Organization’s (WHO) Global Air Pollution and Health Technical Advisory Group, said there is a good understanding that air pollution is “really quite bad” across India but precision is lacking due to the limited distribution of air pollution monitors.

When asked how much time is needed to control air pollution in cities such as Delhi, he cited the example of the US.
