Climatic change is the main cause for melting of glaciers.And one of the the main pollutant responsible for rise in temperature is the smoke and gases produced by burning of fossil fuels.The research carried out at Peshawar indicated that that the number of vehicles in Peshawar increased from 1999 to 2012 more than seven folds.The research was carried out to know the impact of used engine oil in the study area.The aerosol is formed in the air by the escaping gases from the collar of the vehicles.Which is also main cause for the fog formation on the motorway from Peshawar to Islamabad.
The number of vehicles in Hindukush and Himalayan region has increased tremendously and all these vehicles run by Fossil fuel which on burning generate green house gases such as CO,CO2 and in CNG run vehicle methane gas also escape to air.These gases are causing the rise of temperature and so melting of glaciers has also increased.
Another finding of the study is the burning of used engine oil in brick kilns.In the brick kiln used engine oil is used as a chief source of energy and in the brick kiln it is used with other burning material e.g.,wood etc to enhance burning.The used engine oil burn incompletely releasing metals and green gases to the environment.
The policy makers of the region must consider this factor to mitigate the effect of vehicle contribution.
