Visakhapatnam’s air breached national standard on 259 of 382 days; data show winter brings the worst
Visakhapatnam recorded 259 days out of 382 where air quality exceeded the national PM10 threshold, according to data from all ten monitoring stations. The city’s bowl-shaped geography and winter temperature inversions trap pollutants, leading to the worst conditions in December. The findings, released by the Andhra Pradesh Pollution Control Board, highlight the need for stricter measures.
