SPATIAL DISTRIBUTION OF HEAVY METALS DURING PRE-MONSOON AND POST-MONSOON SEASONS IN THE SOIL SAMPLES OF PEENYA INDUSTRIAL AREA, BENGALURU

Abstract

A comprehensive analysis of heavy metals was conducted in the soil samples of Peenya Industrial area of Bengaluru. The study performed at twenty different sampling locations along the industrial area of Bengaluru for the Pre-monsoon and Post-monsoon seasons during the year 2013. The results revealed that in the pre-monsoon season the heavy metals were recorded in the order of Zn˃Fe˃Pb˃Cr˃Ni˃Cd˃Cu˃As and during Post-monsoon season the preference of heavy metals were in the sequence of Zn˃Ni˃Cr˃Fe˃Pb˃As˃Cd˃Cu.. Higher values were mainly observed in the specified sites for heavy metals. These indicate that heavy metals contamination should be taken into account during development strategies to protect the habitat from long term contamination load.
