"Smog with PM pollutants have a very harmful impact on people with respiratory disorders like Acute Respiratory Syndrome (ARI). Exposure to smog for a prolonged duration may increase mortalities related to the respiratory diseases, " warned Dr PC Sahoo, former CDMO at Capital Hospital.

As per the data available with State Health Department, Odisha records 18-23 lakh Acute Respiratory Infection (ARI) cases per year. And the ARI fatalities hover in the range of 50-110 per year. Data shows the State records nearly 2-3 deaths every 10 days during a year.

Real Time Air Pollution In Capital City

The Air quality index today in Jayadev Vihar today at around 8:50 pm is 263, which means the air is hazardous. As per Skymet, mask is must for the sensitive age-groups. In Jagamara, the AQI is 163, which means very unhealthy.

Why Air Quality Worsens?

"Wind is blowing from northeast direction to Odisha carrying significant moisture content. Sufficient moisture on the ground condenses as the ground cools during the night resulting in fog formation," explains former director of IMD, Bhubaneswar, Sarat Sahoo. December and January are the peak months for fog formation, he observed and further added that due to foggy conditions the pollutants get trapped at lower level of air, which results in worsening of air quality here.
