Chennai, June 8:.
Manali, the industrial hub in North Chennai, has emerged as the most severe hotspot for ground-level ozone pollution in India, according to recent data released by the Central Pollution Control Board (CPCB). The alarming trend has raised serious concerns among environmental experts and public health authorities.
A monitoring station in Manali recorded a dangerously high ozone concentration of 500 micrograms per cubic metre on May 19. Earlier in the month, on May 3, another station in the same locality reported a level of 361 micrograms per cubic metre. Both readings far exceed the national air quality standard of 100 micrograms per cubic metre, calculated over an eight-hour average.
Ground-level ozone is a harmful pollutant formed when emissions from vehicles and industrial activities react under sunlight and high temperatures. Prolonged exposure to such elevated levels can lead to respiratory illnesses, eye irritation, reduced lung function, and can particularly affect children, the elderly, and those with pre-existing health conditions.
The sharp rise in ozone pollution in Manali highlights the urgent need for stricter emission controls and improved air quality monitoring in industrial regions. Experts warn that without immediate intervention, the situation could worsen, posing a significant threat to both the environment and public health.
