‘Good ozone vs bad ozone’ at Science City

Jalandhar, September 16

Pushpa Gujral Science City celebrated World Ozone Day by organising a webinar on Good Ozone vs Bad Ozone. Around 150 school students from all over the state participated through virtual mode. Dr Umesh Chandera Kulshrestha, Dean, School of Environmental Science, Jawaharlal Nehru University, New Delhi, was the key speaker at the occasion. He delivered a special talk on Good Ozone and vs Bad Ozone. He said the ozone occurs in two layers of the atmosphere. The layer closest to the Earth’s surface is the troposphere. Here, ground- level or “bad” ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation. The stratosphere or “good” ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the ultraviolet (UV) rays. — TNS
