City night air heavy with pollutants: The Times of India

“If you are taking a joyride or getting a cab home after work at midnight, think twice before sliding down the car window and breathing in deeply. That cool, pleasant breeze is probably bringing in pollutants as well. Air pollution is no longer at its worst only during the day-researchers have started observing midnight pollution as well. Midnight pollution, an effect of meteorological conditions, is a phenomenon observed in highly populated cities with poor air quality such as Beijing and Delhi. Large amounts of respirable suspended particulate matter are released into the air during the day from vehicles. Most of these are pushed to the upper levels of the atmosphere due to high daytime temperatures.” Times of India. Read it on delhiair.org.
