| Effects on Human Health \r\n | \r\n \r\n
| The vehicular pollutants have damaging effects on both human health and ecology. The human health effects of air pollution vary in the degree of severity, covering a range of minor effects to serious illness, as well as premature death in certain cases. These pollutants are believed to directly effect the respiratory and cardiovascular systems. In particular, high levels of Sulphur dioxide and Suspended Particulate Matter are associated with increased mortality, morbidity and impaired pulmonary function\r\n | \r\n
| Vehicular Pollution in Delhi | \r\n \r\n
| Delhi \'s registered vehicular population has nearly doubled to 4.5 million from 2.2 million in 1994, registering a growth rate of 10% per annum. About two-Third of the Motor Vehicles are two-wheelers.Vehicular pollution is considered to be a major source of air pollution in Delhi . As per Central Pollution Control Board, the vehicular pollution load in Delhi increased by nearly 50% in 1995-96 from 1990-91. However, a decrease has been witnessed in recent years with the implementation of several control measures. Vehicular emission load reported by the Central Pollution Control Board | \r\n
| Alternate Fuel to Control the pollution Compressed Natural Gas (CNG) | \r\n \r\n
| CNG (short for Compressed Natural Gas) is emerging as an attractive alternative fuel due to its clean burning characteristic and very low amount of exhaust pollution. It is a mixture of hydrocarbons consisting of approximately 80 to 90 percent methane in gaseous form. It is compressed to a pressure of 200 to 250 Kg/Cm2 to enhance the vehicle on-board storage in a cylinder.Facilities for dispensing of CNG in vehicles are being provided by Indraprastha Gas Limited. Currently, 133 CNG filling stations (as in May, 2005) have been set up in Delhi | \r\n
