Heavy metals concentration in leafy vegetables or in any other edible products causes risk to the human health and long term use of that causes serious diseases concern to the heavy metals. Current research work shows the result related to the contamination and impact of the higher concentration of heavy metals on the health. So for the research work five heavy metals such as Pb, Zn, cd, Cu and Ni were used and their concentration were compared between the washed and unwashed leafy vegetables samples . Leafy vegetables such as spinach, amaranth leaves, wild spinach, fenugreek, cabbage, coriander, purslane and mustard were collected from the different site near to the roadside (location: hoshangabad , khajuri kalan, and ayodhya bypass).Different parameters of risk assessment were analysed in the samples , parameters like Pollution index , hazard ratio , average daily intake etc. All the result compared with the permissible limit of the heavy metals which were helpful in the detection of toxicity level. This study helped in determination of presence of concentration of heavy metals in the samples and as well as its toxicity level. This research work shows the comparative result which helpful in the measurement of the toxicity level.
