Abstract
In this study, the concentration of the heavy metals was determined in road dust samples of the Khitouli village, district Katni, Madhya Pradesh, India. Samples were acquired from the different upper surface of the road where vehicles were busy on the road during January, February and March 2018. A total of 5 metals were selected for the study area to examine the concentration along the road. Samples were analyzed using inductive coupled plasma-optical emission spectrometry (ICP-OES) (Perkin Elmer). The result showed that the average value of vanadium (V) was found maximum at overall sampling locations. The average value of chromium (Cr) was also found maximum at all sampling locations alongwith the road dust. These values were compared from the prescribed maximum permissible limits of the Environmental Protection Agency. The iron (Fe) was found maximum at sampling locations SL-3, SL-4 and SL-1 with the value of 1029.49, 992.52 and 872.32 ppm, respectively. Metal pollution in road dust was estimated on the basis of contamination factor (CF), degree of contamination (CD) and geoaccumulation index (Igeo). The calculated results of the degree of contamination (CD) showed a low to moderate degree of contamination level. Similarly, the index of geoaccumulation (Igeo) gave values in the range between unpolluted to moderately polluted level. The principal component analysis (PCA) suggests that traffic emission and anthropogenic activity are the main sources of metal pollutants on the road.
