Abstract |
|
|
| Sediment samples were collected by a Peterson grab sampler along the Bay of Bengal coastline, from Poombuhar to Karaikal along the South East Coast of Tamilnadu, India to evaluate the degree of contamination and pollution status of the study area. The determined mean metal concentration is in the order of Ti> Fe > Al > Ca > Mg > K >Mn> V > Cr > La > Ba >Pb> Zn > Ni > Co > As. The pollution indices such as enrichment factor (EF), contamination factor (CF) and pollution load index (PLI) were calculated in the sediments to differentiate the origin of metals between anthropogenic and geogenic sources. Using multivariate statistical analysis (correlation coefficients, factor and cluster analysis) the interrelationships among elements are determined. The concentration of the trace elements reported in this work is useful as baselines analysis for sediment quality studies in future. |
