Concentration of heavy metals in Seagrasses tissue of the Palk Strait, Bay of Bengal

Seagrasses are considered as good indicators of heavy metals in the marine environment. Palk Strait is situated in the southeast coast of India, dominated with the seagrasses. The aim of this investigation to measure the various metals concentration (Mn, Fe, Cu and Zn) in two seagrasses species, Cymodocea serrulata, Syringodium isoetifolium in four selected stations (Karankadu, Soliyakudi, Thondi and Sundrapandiyapattinam) along the Palk Strait. In order to get more information and environmental conditions of the experimental area, total metal concentration was determined in coastal water and in the sediment. From the result, C. serrulata accumulates more amounts of metals than S. isoetifolium. Among all the four stations, station III (Thondi) observed high amount of metal concentration in seagrass tissues as well as its ambient environment.
