Trace Metals (Fe, Mn, Zn And Cu) In Sediments From The Gulf Of Mannar Region, Southeast Coast Of India

The distribution of trace metals (Fe, Mn, Zn and Cu) in the reef sediments and seagrass sediments of islands Manalli and Hare in the Gulf of Mannar region has been monitored for a period of one year. Attempt has also been made to relate the sediment particle size with the concentrations of metals. The determined metal concentrations were in the following order : Fe>Mn>Zn>Cu. The differences between seagrass bed and coral reef bed were statistically determined in each island using ANOVA.
