| Scientists have found out that polluted air generated in industries in northern India travel over 2000 km to reach the hills of Darjeeling and islands of Sundarbans in West Bengal.
A huge and thick mass of air carrying particulate matter (PM) of less than 2 micrometre travels to West Bengal under the influence of the strong north-westerly winds, Abhijit Chatterjee, an environmental scientist at Bose Institute in Kolkata told PTI.
Travelling at a speed of about 20 km per hour, the soot or black carbon takes four days to cover a distance of about 2000 km between northern India and parts of West Bengal, he said.
Under a research project, a team of scientists from the institute, installed aethalometers in Sundarbans and Darjeeling and have been monitoring the quality of air since the last few years.
