Figure 122 On Leh-Manali highway Diesel runs vehicles are used for commute, the diesel has a heavy metal concentration which is polluting the adjacent soil along the highway. The car emits heavy metal into the atmosphere which mixes with soil adjoining to the road.
Vehicles constitute one of the most important sources of environmental pollution. Most studies on roadside soil pollution have been carried out in urban areas, where the main fuel used is petrol. These studies indicate that the concentrations of heavy metals associated with vehicular movement decrease with increasing distance from the highway and with depth in the soil profile. In contrast, most of the vehicles that travel along the Manali-Leh Highway in the northwestern Himalayas, India are fueled by diesel. (Dasgupta, 2014) On Leh-Manali highway Diesel runs vehicles are used for commute, the diesel has a heavy metal concentration which is polluting the adjacent soil along the highway. Although the highway was closed to tourists for eight months of the year (according to early studies), army vehicles are
