Toxic Level Heavy Metal Contamination of Road Side Medicinal Plants in Agra Region
The heavy metals Cd, Co, Fe and Mn were determined in 9 samples of medicinal plants taken from roadside area of Agra, Firozabad and Shikohabad situated on NH-2 which are exposed with pollution. They were analyzed for heavy metal contamination by Atomic Absorption Spectroscopy (AAS). The results of AAS shows that the maximum concentration of Fe (154.4ppm) was found in Azadirachta indica (Agra) and the minimum concentration of Cd (0.000ppm) was found in Azadirachta indica (Agra and Shikohabad), Aloe-barbadensis (Agra and Shikohabad) and Eucalyptus globulus (Shikohabad). The phytochemical investigation were performed which show the presence of Alkaloids, Glycosides, Anthraquinones, Phenols and Flavonoids content in the medicinal plants which shows the maximum contents of phenols was found in Eucalyptus globulus (Agra, Firozabad and Shikohabad) and the minimum content of flavonoids was found in Azadirachta indica and Eucalyptus globulus located at Agra, Firozabad and Shikohabad.
