Bengaluru: Pedestrian to Air troubles Walking People


Walking, the healthiest mode of commuting has become more dangerous in vehicle-ruling Bengaluru after a survey exposed a pedestrian to air which is very much worse than travelling in a congested bus.

This paradox was highlighted by a research on the procedure of exposure of residents to air pollution, conducted for the very first time in the city by the Centre for Science and Environment (CSE). Walking around K.R. Circle, for example, exposes a pedestrian to air that is 1.5 times even worse than that being breathed in by a passenger in a BMTC bus on the choked stretch of Hosur Roadway from Brigade Road to Electronic City.

“The exposure is even worse thinking about that those strolling or cycling breathe faster and breathe in more air than those who travel by automobile,” said Anumita Roychowdhury, Executive Director, Research and Advocacy for CSE, who supervised the research study performed in the second week of December.

But it’s not that those cocooned in air-conditioned vehicles are safe. While driving through extremely contaminated roadways, they might be taking in air two times as bad as the prescribed limitation.

Air Pollution

Presently, the pollution control panel steps ambient pollution with machines continued rooftops. This yields the cloud of pollution that hovers around the city.

Nevertheless, it is on the street that commuters and pedestrians ‘feel’ the smoke and noxious fumes from automobiles. The street-level exposure was discovered to be between 3 and 12 times more than what is measured by the Central Pollution Control panel in Bengaluru.

The area with the worst tape-recorded particulate matter pollution, which is accountable for lung health hazards such as asthma, is Peenya.

Only a fourth of the fleet of the BMTC complies with the Bharat Stage IV norms for diesel engines that entered into force in 2011.

Out its 6,429 buses, almost 1,000 buses follow requirements set before 2003.

CSE, which drew attention of the Supreme Court to the disproportionate contribution of diesel engines to air pollution in Delhi, thinks that these cars can contribute approximately five times more than a fuel variation.

B. Mukkanna, Chief Mechanical Engineer, BMTC, says, “The federal government is mulling over adding 3,500 buses to its fleet. Given that all these will be of the current requirements, the situation will enhance.”

The corporation did attempt making use of emission-free electrical buses, but backed out due to the expensive expense of the automobile.
