Rising temperatures and construction activities in the city cause deteriorating air quality

Increasing temperatures and construction activities are causing a rise in dust particles, leading to deteriorating air quality in the city.

Over the past two weeks, temperatures have been on the rise, with maximum temperatures nearing 35 degrees Celsius. For almost a week, daily temperatures have consistently reached around 34 degrees Celsius. This increase in temperature has resulted in a fluctuating Air Quality Index (AQI), with hot winds affecting residents. The high levels of dust in the air are contributing to skin and respiratory issues.

Following the fare hike of 'Namma Metro', traffic congestion has increased on major roads like Tumakuru Road and Mysore Road during the morning and evening rush hours, further increasing the presence of pollutant particles in the atmosphere. Meanwhile, white-topping works are progressing on certain city roads, including J.C. Road, and various metro line constructions from Central Silk Board to Kempegowda International Airport are currently underway, which are also contributing to traffic congestion.

According to the Karnataka State Pollution Control Board (KSPCB), air quality monitoring stations in regions such as Silk Board, City Railway Station, BTM Layout, Jayanagar, and Bapuji Nagar, which had maintained "satisfactory" air quality levels in January, have now reached "moderate" levels. Days this month have seen the presence of harmful PM-10 (particulate matter) and PM-2.5 particles.

 The acceptable limits for PM-10 and PM-2.5 in the air are 100 micrograms and 60 micrograms, respectively. However, recent analyses indicate that in some instances, the concentrations of these particles have exceeded the prescribed limits.

A KSPCB environmental officer highlighted, "High temperatures lead to the drying of grass-like vegetation, which reduces dust on the ground. As dust particles enter the air, the air quality declines. Rain can help wash away the dust."

An official from the board explained that if the air quality index is below 50, health effects are minimal. However, when the AQI is between 51 and 100, respiratory issues may arise, and when it reaches between 101 and 200, respiratory and cardiovascular problems become a concern.

Moreover, skin-related issues, including rashes and irritation, are on the rise due to the hot weather, leading to an increase in patients seeking treatment, noted Dr. Girish M.S., a dermatologist at ESI Hospital, Rajajinagar.
