Abstract:
Soil is the most important component of Earth ecosystem, which has four key functions for the growth of plants, is a means of storage, supply and purification of water, is a modifier of the Earth’s atmosphere. For the present study, six (6) soil samples were examined for heavy metals, Iron, Copper, Zinc, Manganese, Nickel and Lead analysis of soil samples. Soil samples were collected from the six different villages of Tengnoupal district (Moreh, Machi, Langol, Tengnoupal, Khunbi Tuinem and Kangoi Khullen), Manipur. The soils were analysed for pH and total concentration of heavy metals by using Atomic Absorption Spectrometer (Perkin Elmer A Analyst 500). The results of the study revealed that Iron (Fe) present in the soil sample are within the permissible limits as per FAO/WHO, 2007, India Standard Awashthi, 2000. Zinc, Copper, Nickel, Manganese and Lead are present in lower than that of Fe in all five samples and also lesser than the permissible limit. The trend of the average content of heavy metals in soil of the studied areas found in the following order Fe > Mn > Cu > Zn > Ni > Pb. Therefore, the soils studies were not harmful, so there is no serious implication for health hazard.
