Bengaluru there is population very much we have to save Bangalore but we can't do anything please give me thanks please
Answer:
Bengaluru is in the grip of rising air pollution. Official ambient air quality monitoring has already shown 57% increase in particulate matter in just 4 years (2010-2014) and 23% in one year (2013-14- 2014-15). In more than 85% of monitoring locations the levels have exceeded standards.

CSE exposure monitoring has provided clinching evidence of alarming dose that an average Bangalorean breathes on a daily basis in different parts of the city – 3 to 12 times higher than the ambient level recorded by official monitors.
With growing vehicle numbers and resultant congestion and dieselisation, air pollution is a growing concern in the city. The city is losing its inherent advantage of dominant commuting practices – use of bus and walking at the cost of clean air and public health.
Bangalore needs stringent measures including leapfrogging emissions standards to Euro VI, curbing dieselisation, scaling up of integrated public transport, car restraints and walking for clean air.
Centre for Science and Environment (CSE) released its results from its recent analysis of the official ambient air quality monitoring in Bengaluru as well as its own exposure monitoring in Bengaluru. This has exposed very high level of pollution within the breathing zone of people. This indicates serious public health risk.
The relatively lower ambient levels as compared to northern cities like Delhi should not breed complacency, as most of the health effects occur at a level much lower from the current standards. Moreover, direct exposure to toxic fumes is very high in the city. Improving urban air quality and protecting the sustainable urban commuting practices are some of the toughest challenges. “Bengaluru, while having made some significant strides in meeting air quality challenges, faces newer challenges. It needs technology leapfrog, scaling up of public transport, integrated multi-modal transport options, car restraints and walking for clean air,” said Anumita Roy Chowdhury, Executive Director, CSE.
This emerged out of the media workshop conducted in Bangalore by the New Delhi-based research and advocacy organisation, CSE. It was organised to share concerns and find solutions to the daunting air pollution and mobility challenges facing our cities. Half of the urban population breathes air laced with particulate pollution that has exceeded the standards. The dialogue unveiled the unique challenges and the emerging good practices to draw lessons for the roadmap for the country.
What has CSE done?
CSE has analysed the ambient air quality data from official monitoring stations of KSPCB, to understand the real time trend over time in Bengaluru.
In addition, using its realtime and portable monitor, CSE has also carried out a rapid diagnostic exposure monitoring in different locations of Bengaluru to understand what level of pollution people are exposed to on a daily basis.
What does official ambient monitoring show?
Among the key southern cities that are monitored by Central Pollution Control Board, Bangalore has recorded 57% increase in PM10 between 2010 and 2014, highest amongst southern cities just in four years. Only in one year – 2013-14 and 2014-15, the levels have increased by 23%. At the same time, NOx levels, though generally low, have also begun to increase.
Analysis of the air quality data between October 1 and later part of November, 2015 shows rapid build-up of pollution in the city. It increased several fold. “This demands immediate intervention to prevent further worsening and reversal of the trend to protect public health,” said Roy Chowdhury.
The CPCB data shows that in 85% of location the levels have begun to exceed the standards. The worst hit pollution hotspots include Graphite India Whitefield; AMCO battery Mysore Road; Silk Board Hosur; and Victoria hospital.
Results of CSE’s exposure monitoring: High exposure to toxic fumes
CSE has used a state of the art portable air quality monitoring equipment to track how much pollution an individual in Bengaluru is exposed to while travelling. Dustrak Aerosol monitor measures the mass and size fraction of the particulate matter. The monitoring was done in various land use areas including sensitive areas like hospitals (Fortis, Manipal Hospital), Schools (Bishop Cotton boys and girls), industrial area (Peenya), Electronic city, and residential areas. The monitoring was also done on different transport modes including walking, bus, car and auto. This exposure has also been compared with the background ambient levels monitored by the Central pollution control board for the city.
