Heavy metal enrichment in seagrasses of Andaman Islands and its implication to the health of the coastal ecosystem
85-91Concentration of metals (Mn, Al, Fe, Cr, Cu,
Zn, Pb, Cd, Co and Ni) in eight different seagrass species of Andaman Islands
were analyzed using Inductively Coupled Plasma Optical Emission Spectrometer.
The concentration of Mn was maximum in almost all the seagrasses, whereas Co
recorded minimum concentration. The concentration of various metals are showed
different concentration Mn (508-2224µgg-1), Al (418.74-1064.8µgg-1),
Fe (525.6-1920.4µgg-1), Cr (58.28-249.44µgg-1), Cu
(30.52-109.52µgg-1), Zn (28.88-85.52µgg-1), Pb
(4.16-17.72µgg-1), Cd (2.24-6.92µgg-1), Ni (1.76-10.04µgg-1)
and Co (1-3.28µgg-1). The results found that there where
interspecific and intraspecific differences in the accumulation of different
metals in seagrasses. However, there is no significant variation in metal
concentration in seagrasses was obtained between stations. The study clearly
indicates that the seagrasses can be used as a potential mean for monitoring
the metal concentration in coastal environs
