STUDY OF HEAVY METAL CONTAMINATION IN SOIL SURROUNDING PIRANA LANDFILL SITE BY ATOMIC ABSORPTION SPECTROMETER
Keywords:Atomic Absorption Spectroscopy, Pirana, heavy metal, Soil Contamination, AAS.
Accumulation of Heavy Metals in the soil leads to contamination of soil; which is one of the prevailing issues. Heavy metals released in the environment are majorly infiltrated into soils and most metals do not undergo chemical degradation, thus their concentrations in soils persevere for a long period. The presence of Heavy metals not only create adverse effects on ecosystem but also affects the engineering properties of soil. Hence there lies the importance of determining Heavy Metal Concentration in Soil. In the present study Concentration of Lead, Copper and Zinc were determined in soil samples collected surrounding the Pirana Landfill site. The soil samples were collected from the 8 co-ordinates and analysed with the help of AAS. Some Soil Samples showed considerably high amount of heavy metals while for some soil samples, the concentration of heavy metals was appeared to be within permissible limits.
