Heavy Metals are natural constituents of soils and their concentration varies depending on parental materials. The content of heavy metals in soils has increased due to human activities as distribution of fertilizers, pesticides, industries, waste disposal and air pollution. Due to these activities the life capacity of soils decreased, especially where the natural background is already high because of natural parental richness in heavy metal. As a matter of fact it is very important to distinguish between the natural background values and anthropogenic inputs, and to understand that the background values change from area to area and with the scale of the area investigated. Five stations along Buddha Nullah River in Ludhiana region were chosen to collect and assess the Mn, Ni, Pb, Cu and Cd contamination in sediments by using pollution load index (PLI) and geo-accumulation index (I-geo). Cd was found at the most reduced focus went between 0.5-1.4 µg/g dry weights. While, Mn was the most noteworthy running between 147-343 µg/g dry weight. Geo-aggregation record shows that the dregs in the greater part of considered stations were marginally contaminated (grade 1) as for Pb and Cd, while the residue in completely examined stations were unpolluted (grade 0) as for Mn, Cu and Ni. The upsides of Pollution Load Index (PLI) were observed to be exceptionally low, and shifted between 0.41-0.97, demonstrating that the contemplated stations in Buddha Nullah stream were unpolluted by absolute of studied heavy metals.
