BU’s year-long study confirms BM’s test drive of April 27 An ongoing study by a team of researchers from Bangalore University has mapped out air pollution data at the city’s busiest junctions. The Department of Environmental Science at BU concluded that longer durations of time spent on these listed signals may cause damage to lung tissue. Out of the 10 busiest traffic junctions identified by Bangalore Traffic Police, the team of researchers zeroed in on six junctions – Mysore Road Junction, Mehkri Circle Junction, Majestic Junction, Silk Board Junction, Tin Factory Junction and Jalahalli Cross Junction. The study has been on since February 2018 to present. In the study, it was found that Particulate Matter (PM) 10 levels were above the Central Pollution Control Board (CPCB) standards, more than 100 microgram per cubic metre (mg/m3), while the PM 2.5 levels were within the prescribed range that is 60 mg/m3.
