The problem, broken down
- Who it hurts
- Residents of Visakhapatnam, including children, older people and people with asthma or heart disease, and those living near the port and industrial areas.
- The moment
- A December week when every daily reading is poor or worse and there is no local warning or advice for that neighbourhood.
- What people do today
- Readings come from a handful of manual and continuous stations, and residents have to look up the national AQI themselves after the fact.
- Why it's unsolved
- Monitoring is thin and uneven across the city, the sources of pollution have not been quantified, and the seasonal pattern isn't turned into advance warnings.
- What solved looks like
- A free neighbourhood air alert for Visakhapatnam, by SMS and web, that combines official station readings with forecasts of winter inversion conditions, warns a day ahead when air is likely to turn poor, and gives plain health advice.
Evidence
Every claim is tied to the source it comes from- 1Across the 13 months from September 2025 to September 2026, air quality was above the national standard of 100 on 259 of the 382 days with a reading.
- 2Of the 30 daily readings for December 2025, 25 were in the 'poor' or 'very poor' categories, and the average daily AQI that month was 255, nearly three times the 88 recorded in October.
- 3Between November and February, 51 of 116 readings (44%) were 'poor' or worse; only four of the 266 readings in the other nine months were in those categories.
- 4An APPCB scientist said the city's bowl-shaped terrain obstructs the dispersion of pollutants and a winter temperature inversion traps them and pushes up the AQI.
- 5Until the Andhra University source apportionment study's final report is received, the shares of industry, vehicles and road dust in the city's pollution remain unquantified.
