Accumulation of lead (Pb) due to vehicular traffic activities on the road-side soil and farmland is a potential environmental hazard effecting the eco-system. Environmental pollution of heavy metal like lead(Pb) from automobiles has attained much attention in the recent past. The present research was conducted to study the influence of physiochemical characteristics on lead (Pb) concentration in road-side soil and farmland along a national highway-4 from Mysuru to Bengaluru. Conventional and analytical methods were employed for the determination of these physiochemical parameters. 35 soil samples were collected from the left and right side of the highway. Samples were collected at a distance of 10m and 200m away from the road edge. Amount of lead (Pb) level in soil was analyzed by using x-ray florescence spectrophotometer (model xrf-α-4000) and soil physiochemical properties of the soil were also determined. The results of the physiochemical analysis showed that the pH values in all sampling sites ranged from 3.55 to 6.58 and 3.65 to 6.36 at 10m and 200m away from the road respectively, indicating the acidity of soil. The total organic carbon values ranged from 0.00264% to 0.773% and 0.088% to 0.715%at 10m and 200m away from the road respectively, indicating the presence of organic matter and micro-biological activities in the soil sample. The conductivity values ranged from 0.002ms/gm to 0.026ms/gm and 0.002ms/gm to 0.036ms/gm at 10m and 200m away from the road respectively, indicating significant presence of some soluble inorganic salts. The road-side soil and farmland soil samples also had significantly high contents of lead (Pb) and its level increased with increasing traffic activities.
