HEAVY AND TRACE METALS IN MANAKUDY ESTUARINE CORE SEDIMENTS, SOUTH WEST COAST OF INDIA

SUGIRTHA P. KUMAR AND M.S. SHEELA

Abstract

Manakudy estuary is the second largest estuary in Kanyakumari District. It has a total area of 145 hectares. It is situated about 8 kilometers North west of cape comorin falling within the latitude 80 41 and 80 21 1N and longitude 770 261 and 770 301E. The sediment core characteristics were studied in 3 stations viz S1, S2, & S3. The sediments were grouped under the following types viz sand,silt and clay. The sediment texture showed marked variation with highest values of sand at station S2&S3. The amount of silt was higher at station 1. The amount of clay was higher at station 1 and low at station 2. The determination of elements in sediments in relation to depth showed that various elements were present in different concentration. The maximum recorded values of elements in Manakudy estuary are Cu 17.14Pb 29.54, Mn 103.7, Ni 94, Zn 52, Al 9.4, Co 15.72 and Cr 78μgg-1. The ANOVA results showed significant correlation in Ni, Zn, Al between samples and stations. The enrichment factor-EF>2; Anthropogenic factor-AF>1; Index of Geoaccumulation- Igeo<1 and Contamination factor-Ci f<1.
