SULPHUR IN PETROL AND DIESEL (A CASE STUDY)

Abstract

Air pollution in developing countries are increasing most rapidly. Air pollution is caused mainly by transport, industries and fossil burning and contributions by minor industries like cement, mining etc are observed. The air quality crisis in cities is often attributed in large measures (40%–80%) to vehicular emissions. Most of the cities are growing rapidly. Moreover, urban populations are growing at a faster rate than national averages, as subsistence workers migrate from rural areas to the cities in search of disposable income. Existing cities are expanding and new cities are coming up. This rapid growth of the urban population also brings with it an increasing demand for Transportation. India has witnessed a rapid increase in its vehicle population from 3 million vehicles in the 1960 to 40 million in 2002. The unbridled growth of the vehicular population has resulted in the deterioration of environmental quality. Vehicle emissions by burning of diesel and petrol include oxides ...
