Abstract:
Distribution of toxic metal in the sediment core is an important area of research for environmental impact studies. Sediment
cores were collected from two prominent region(C1 and C2) of CE and subjected to geochemical analysis to determine
distribution of toxic metals (Cd, Co, Cr, Cu and Pb ), texture characteristics, total organic carbon (TOC) and CHNS.
Statistical analysis was done to understand the interrelationship between the components. In the studied cores, metal
contamination level was identified for Pb, Cu; Cr, in C1 and C2 respectively. The metal distribution depends on the
granulometric factor, geogenic mineral components and anthropogenic input. Correlation analysis (CA) and Principal
component(PCA) analysis also support these results

Abstract:
This article present the result from a study of two sediment cores collected from the
environmentally distinct zones of CES. Accumulation status of five toxic metals: Cadmium (Cd), Chromium
(Cr), Cobalt (Co), Copper (Cu) and Lead (Pb) were analyzed. Besides texture and CHNS were determined to
understand the composition of the sediment. Enrichment Factor (EF) and Anthropogenic Factor (AF) were
used to differentiate the typical metal sources. Metal enrichment in the cores revealed heavy load at the
northern (NS1 ) region compared with the southern zone (SS1). Elevation of metal content in core NS1 showed
the industrial input. Statistical analyses were employed to understand the origin of metals in the sediment
samples. Principal Component Analysis (PCA) distinguishes the two zones with different metal accumulation
capacity: highest at NS1 and lowest at SS1. Correlation analysis revealed positive significant relation only in
core NS1, adhering to the exposition of the intensified industrial pollution
