The quality of roadside soil along the NH3 highway of high traffic density at Morena- M.P. was studied during 2010-11 at 12 different locations. The roadside soil was found to be highly contaminated. This is evident from the modification of the soil pH, Electrical conductance, Water holding capacity and other Physico-chemical properties when compared to natural soil. The presence of heavy metals like Zn, Cu, Mn, Fe in the roadside soil was also considerable.

Introduction

Around the world the transport sector, which includes automobiles, trucks, trains, ships and aeroplanes is contributing ever increasing shares of the total air pollution burden. The pollution of soils by heavy metals from automobile sources is a serious environmental issue. Results show that roadside soil near motorways is heavily polluted by heavy metals from automobiles.1-2Changes in the composition of the urban atmosphere are caused largely by traffic induced pollutants3mainly carbon monoxide, nitrogen monoxide, dust and as well as various types of non methane hydrocarbons, in particular benzene, toluene and xylene. Secondary trace gases which can be formed from these precursor substances in certain photochemical reactions. The soil and the shrubs near the road are immediate receptors of the contaminants generated by plying of various types of vechicles through exhaust emission and other processes. Vehicular emission are known as the single most important contributor to the atmospheric pollution. The vehicle associates components constitute nearly 70% of the contaminants input to roadside soil,4the rest of the input being from surface binders used in road constructions, dust fall and precipitation, road surface erosion, animal wasts and vegetable debris etc. Vehicular emission and evaporative emissions contents may contain unburnt hydrocarbons including polycyclic hydrocarbons and trace metals like Pb, Cd, Zn, Cu, Mn and Fe etc. The retention of various contaminants by the soil results in modification of its physio-chemical characteristics such as pH, conductance, texture etc.5Thus it is expected that the roadside soil has a high degree of contamination & its quality is a definitive indicator of vehicular pollution.

The location of Morena city is between the two important and historical cities Agra and Gwalior by national highway NH3. The quality of roadside soil along the major roads of known high traffic density of Morena will be studies of different location. The present study is a modest attempt to understand the impact of vehicular emission on the city roadside soil. For this purpose physico-chemical characteristics of the roadside soil samples were studies carefully during 2010-11.

Materials and Methods

Surface soil samples were collected from the roadside at 12 locations in high traffic density areas of Morena city. A set of samples was also taken from a zero traffic zone for comparison and correlation purposes. The sampling locations with distance and direction from the reference point (Agriculture-Center Morena) are given in Table 1. The reference point is atleast 4 km away from all forms of traffic is therefore considered as “Control”. The samples were analysed for a no. of physical and chemical parameters as per standard procedure.6-7

Results and Discusion

The results of the analysis are presented in Table 2. The values represent averages of at least three measurements.

The normally acidic soil has turned alkaline due to contamination. The electrical conductivity values were also slightly higher than that of the control (0.10), indicating the input of some soluble electrolytes to the roadside soil due to various traffic related activities. Water holding capacity values (40-60%) for 0 feet distance and (35-65%) for 50 feet distance are lower than the control (72%) . Presence of hydrophobic matter often reduces water holding capacity and the results have indicated the entry of foreign matter to the roadside soil impairing its quality.

Conclusion

The present study shows conclusively that three is a large input of contaminants from vehicular emission and associated activities to the roadside soil. These inputs impair the quality of the soil nearby reducing its capacity to support plant life. While there may be some amount of favourable impact due to a few contributions, most other contaminants interfere with the natural properties of soil. Input of heavy metals on roadside plant leaf and entry of toxic organics such as the polyaromatic hydrocarbons are under investigation.
