An Assessment of Heavy Metal Bioaccumulation in Asian Swamp Eel, Monopterus albus , During Plowing Stages of a Paddy Cycle

摘要: Livers and muscles of swamp eels (Monopterus albus) were analyzed for bioaccumulation heavy metals during the plowing stage a paddy cycle. Results showed bioaccumulated more highly in liver than muscle. Zinc (Zn) was highest metal (98.5 ± 8.95 μg/g) muscle (48.8 ± 7.17 μg/g). The lowest cadmium (Cd) (3.44 ± 2.42 μg/g) copper (Cu) (0.65 ± 0.20 μg/g). In sediments, Zn present at mean concentration (52.7 ± 2.85 μg/g), while Cd had (1.04 ± 0.24 μg/g). biota-sediment accumulation factor (BSAF) Cu, Zn, nickel (Ni) tissue greater corresponding BSAF tissue. For three stages, concentrations significantly correlated between tissues all cases, sediment either or most cases. Mean measured below maximum permissible limits established by Malaysian U.S. governmental agencies, therefore regarded as safe human consumption.
