Hyderabad: Centre for Science and Environment (CSE) ki ek nai report ke mutabiq is saal garmi ke dauraan Hyderabad mein ozone pollution 22 din tak safe limit se upar raha. Yeh data March 1 se May 31 ke beech record kiya gaya hai jisme Hyderabad ke saath Mumbai, Kolkata, aur Bengaluru bhi shamil hain jahan surface-level ozone concentrations mein tez izafa dekha gaya.
Report ke mutabiq Hyderabad mein ozone levels 22 alag dinon mein permissible threshold se upar gaye, jahan peak concentration 51 micrograms per cubic metre tak pahunchi. Pichle saal ke mukable mein Hyderabad ki ozone air quality mein 55% ki girawat dekhi gayi.
Mumbai mein situation aur bhi khatarnaak rahi jahan 32 din safe limit ko cross kiya gaya aur ek din ka highest reading 90 micrograms tak pahucha. Wahan air quality mein 42% ki girawat hui. Kolkata ne bhi Hyderabad ke barabar 22 unsafe days record kiye aur 45% ozone quality decline dekha gaya.
Bengaluru mein halanki ozone levels ne 45 din tak limit cross ki, lekin pichle summer ke mukable mein is baar 29% behtari record ki gayi.
CSE ne bataya ke ground-level ozone ka formation vehicles, power plants aur industries se nikalne wale nitrogen oxides, volatile organic compounds (VOCs), aur carbon monoxide ke chemical reactions se hota hai. Ye pollution agar control na kiya gaya to public health ke liye ek serious risk ban sakta hai.
CSE ki executive director Anumita Roy Chowdhury ne warn kiya ke is tarah ke pollution trends agar jaari rahe to urban populations ke liye breathing-related problems, respiratory illnesses, aur chronic health impacts ka khatra barh jayega.
