Heavy metal fractions and ecological risk assessments in sediments and seagrasses along the tropical coasts in Phang-Nga Bay, Andaman Sea
Along Phang-Nga Bay, most sediment metals were bound to crystalline phases and therefore appeared to have low bioavailability, but the potentially mobile fractions of Zn, Ni, and Cd averaged above 10%, indicating medium risk. Enhalus acoroides accumulated Cd, Zn, and Cu efficiently and preferentially translocated metals to leaves rather than rhizome-root tissues.
