Down core
variations in heavy metal concentrations at every 2.5cm increment was
determined. Four cores were collected to assess the heavy metals - Cd, Cr, Cu,
and Mn in the Ennore creek and one core was collected from the sea. Mn is
present in highest concentrations in all cores ranging 0.9 to 4ppm. Results were
processed used correlation and factor analysis. Results of statistical analysis
show that positive correlation exists among fine grained particles and heavy metals.
Correlations of OM with heavy metals is also
observed. Results confirm that fate of heavy metal in sediment is influenced by
many parameters. Sediment pollution assessment was carried out using
geoaccumalation index, anthropogenic, enrichment and contamination factor. Muller’s
Igeo classification places Ennore under class
0 - uncontaminated except C3 which falls under class 6 (very highly
contaminated). EF places Ennore under minimal contamination. According to Pollution
Load Index calculations Ennore shows low to moderate degree of contamination.
