ABSTRACT
Using standard analytical procedure, the absorption rate (bioaccumulation factor) of heavy metals from sediment to shell of T. fuscastus showed the sequence result: the heavy metals in the shell showed their sequence as follows: Zn (30.01 ug/g) > Cu(25.27 ug/g) > Fe (11.11 ug/g) > Rd (5.90 ug/g) > Cd (0.35 ug/g). Heavy metal in the sediment sample showed their sequence as follows: Rd (29.40 ug/g) > Zn (21.89 ug/g) > Fe (21.29 ug/g) > Cu (18.22 ug/g) > Cd (3.21 ug/g). Bioaccumulation factor sequence was Zn (1.40 ug/g) > Cu (0.72 ug/g) > Fe(0.52 ug/g) > Rd (0.20 ug/g) > Cd (0.11 ug/g).
