Bangalore, Among World's Top Polluted Megacities

Bangalore: Living in a megacity isn’t easy, it’s rather very challenging. And one of the challenges to deal with is the increasing level of pollution in these cities caused by traffic, industry and natural minerals. A study reported that India’s hub for IT sector, Bangalore, is one among the top polluted megacities in the world.

189 megacities were tracked for pollution by the scientists at Tel Aviv University. The study revealed that cities with population that exceeds 2 million were the hotspots for high pollution. Out of these 58 megacities Mumbai, Tokyo and New York also showed the population that amounts over 5 million. The study was put together by collaborating eight years of data collected from three of NASA’s high tech aerosol monitoring satellites.

India, Northeast China, the Middle East and Central African cities are the foremost showing increase in pollution rates including Bangalore, with a 34 percent average rise in aerosol concentration from 2002 to 2010, reported by Tel Aviv University's American Friends (AFTAU) website.

The smog that often covers megacities is in fact a thick cloudy layer several hundred meters over the Earth’s surface, which contains the particle of pollutants.
