Abstract

In this study road side sediments sample were collected in Mumbai- Pune National Highway for a stretch from Pnavel to Pune and subjected for heavy metals (Zn, Cr, Cd, Pb) analysis through Atomic Absorption Spectroscopy (AAS) Technique. Totally 25 sites were selected for sediments sample collection and sediment samples were collected as per standard methods. The concentration of heavy metals present in the road site sediments from the study area was determined by Atomic Absorption Spectrophotometer AAS7000. From the toxicity parameter results, it is observed that the contamination of the road site sediments in the study area by the metals Cd, Pb and Zn is mainly due to the anthropogenic activities (man-made activities) like industrial effluents, vehicular emission and wastages supplied to environment on the travel and uncontrolled input of sewage, garbage into the road side environment.

Keywords: road side sediments, heavy metals, Atomic Absorption Spectrometer.
