Development of transport facilities unconsciously affects the natural resources and biodiversity. Non-point sources of traffic related pollution has become a major concern as they are more difficult to be defined or controlled as compared to the point sources. The environmental pollution of heavy metals from the automobiles has attained much consideration in the recent past. The present research was conducted to study the levels of chromium, lead, cadmium and nickel in the roadside farmland soil and crops cultivated there. Soil samples were collected from a farmland at distances of 0, 50, 100 and 1000 mtrs from the road edge. The concentration of the heavy metals in the soil samples and the crops (pigeon pea, wheat, mustard) has shown a decreasing trend with the increase in the distance from the road edge, thus indicating their relation to the traffic and the automotive emissions. Deposition of these heavy metals in the environment and the crops in particular could pose health risk to humans through food chain contamination.
