Air pollution in delhi

  2. 2. In Delhi , air pollution is one of the most critical problem being faced by the public and concerned authorities. According to World Health Organization, Delhi is the fourth most polluted city in the world in terms of Suspended Particulate Matter (SPM) AIR POLLUTION IS HIGH DUE TO :-- 1. Phenomenal growth in the number of motor vehicles (65%). 2. Coal based power generation unit and other industries (35%). Annual average maximum levels of SPM in Delhi’s air has increased from 7.6 times the permissible limit in 1987 to 16.7 time in 1995.
  3. 3. LOCATION WISE POLLUTION IN DELHILOCATION WISE POLLUTION IN DELHI Air quality monitoring studies have been conducted using Ambient Air Quality Monitoring Mobile laboratory at 11 locations. It monitors with respect to Sulpher Oxide, Nitrogen Oxide, RSPM and CO. The data collected at these locations indicate high SPM 367-462 mgm/cubic m against the standard of 140-368 mgm/cubic m. The society of Indian Automobile Manufacturers (SIAM) says that cars with diesel have increased to 30% in 1 ½ years and is expected to rise by 50% in 2010. About 3000 tones of air pollutant are emitted everyday in Delhi.

  5. 5. Study by Centre for Science and environment reveals the reduction of SPM on the CNG use in Delhi :-- Emission Benefits of Replacing Conventional Diesel with CNG in Buses Fuel Pollution Parameter CO NOx PM Diesel 2.4 g/km 21 g/km 0.38 g/km CNG 0.4 g/km 8.9 g/km 0.012 g/km % Reduction 84 58 97
  6. 6. In my locality (Officer’s Rest House, near Connaught Place) the number of cars are 8 and motorcycles, 2.Out of which three vehicles use CNG, two use petrol and five diesel. The ratio of vehicles using CNG to that of petrol or diesel is 3:8 . In Delhi, during 1975 there were only 2.35 lacs of vehicles and these have increased drastically to 46 lacs.It is expected that the number of vehicles will go upto 60 lacs by 2011. At present, about 45% of total vehicles are using CNG in place of petrol / diesel.
