Study on raising Meretrix lyrata () clam in medium containing copper (Cu) and lead (Pb) at different concentrations for 28 days to assess the bioaccumulation ability of needles This type of clam into the body. Clam culture environment is prepared by dissolving metal into the water phase of rearing tanks (containing seawater, sediment and clam collected from Tien river estuary in Tan Thanh commune, Go Cong Dong district, Tien Giang province). with initial concentrations: 30 µg Cu / L and 50 µg Pb / L (abbreviated to 30Cu-50Pb), 60Cu-150Pb, 100Cu-300Pb and 200Cu-600Pb. After 2 days of exposure, the metal concentration in the water decreased rapidly. | Bioaccumulation of copper and lead by bivalve Meretrix lyrata cultured in water – sediment environment
