Heavy metal Concentration in the Components of Golden apple snail (Pomacea canaliculata) and Pond snail (Filopaludina martensi)

Abstract

The objective of this research was to analyze heavy metal bioaccumulation (Cd, Pb, Hg and As) in shell, meat and internal organs of golden apple snail (Pomacea canaliculata) and pond snail (Filopaludina martensi) by Atomic Absorption Spectroscopy (AAS). That result presented the accumulation of Cd, Pb, Hg and As from Pomacea canaliculata shell was 0.0043, 0.0660, 0.6342, 2.5827 mg/g respectively, from meat was 0.0004, 0.0173, non-detected, 0.1693 mg/g respectively and internal organs was 0.0012, 0.0357, 0.0494, 1.0377mg/g respectively. While, the concentration of Cd, Pb, Hg and As in the shell of Filopaludina martensi was 0.0039, 0.0567, 0.5933, 2.4663 mg/g respectively, in the meat was 0.0007, 0.0313, 0.0224, 0.2870 mg/g respectively and internal organs was 0.0014, 0.0360, 0.0948, 0.9900 mg/g respectively. The heavy metal accumulations from snail shell are more than meat and internal organs because the major component of shell has CaCO3 which is exchange of ion between Ca2+ with positive ion of heavy metal.
