A Study of Heavy Metal Contamination in Roadside Soil & Vegetables. From Vehicular Emissions, Seasonal Variations, Distance Wise Variations

      Аннотация: Environmental pollution of soil, plants and deposits around highways endanger urban environment through heavy metals as the byproducts of vehicles and urban industries along with other pollutants.Due to a slow traffic movement and long stops, tires undergo comparatively more abrasion due to repeated brakes and this intensifies, zinc discharge and lead releases from automobile fuels ,all of which are being factors that increase the metal contents of runoffs of roads.The transport pathways and effects of these heavy metals depend on arrange of physical and chemical properties including pollutant concentration, the size spectrum of heavy metal containing particles and the chemical form in which the metals occur.In the present study we have seen the effects of heavy metals on roadside soil quality and plant nutrition in Agra District (The City of TAJ MAHAL). The values of the heavy metals have been compared with results found by other investigators in various countries worldwide.
