Visakhapatnam Air Toxic 259 Days: National PM10 Limit Breached Citywide

Visakhapatnam, a major port city on India's eastern coast, recorded dangerous levels of particulate matter (PM10) on 259 of the past 382 days, according to data from the Andhra Pradesh Pollution Control Board (APPCB). All 10 air quality monitoring stations in the city breached the annual PM10 limit over a 12-month period, indicating widespread and persistent air pollution.

The APPCB scientist attributed the severe pollution to Visakhapatnam's bowl-shaped terrain, which traps emissions from vehicles, industries, and construction, and to winter temperature inversions that prevent pollutants from dispersing. The data show that winter months bring the worst air quality, with PM10 levels often exceeding national standards by a significant margin. The national PM10 standard is 60 micrograms per cubic meter (annual average), but many Indian cities routinely exceed this limit.

The findings raise serious public health concerns for Visakhapatnam's residents, who are exposed to harmful air throughout the year. Prolonged exposure to PM10 can cause respiratory and cardiovascular diseases. Environmental groups are calling for urgent action, including stricter emission controls, improved public transport, and real-time air quality monitoring. The APPCB has not yet announced specific measures to address the crisis, but pressure is mounting on local authorities to implement a comprehensive clean air plan.
