Question

Which of the following is not a preventive measure of air pollution?

Options

• Use of public transport

• Setting up thermal power stations away from the cities

• Carpooling

• Treatment of industrial effluents

Answer 1

Treatment of industrial effluents

Explanation:

Use of public transport and car‑pooling reduces vehicular emissions, and locating thermal (coal) power stations away from cities reduces exposure of urban populations to their smoke and particulates. Treatment of industrial effluents is primarily a measure to prevent water pollution, not air pollution.
