BIOAKUMULASI KADMIUM (Cd) PADA MANTEL, INSANG, dan GINJAL KERANG AIR TAWAR Elongaria orientalis (Lea, 1840)
Abstract: Cadmium (Cd) is one
of non-essensial metals and toxic in low concentration. Cd polution in
freshwater ecosystem from the usage of Cd in many industrial activities can
interfere biology system of aquatic animals. Evaluation of heavy metals in freshwater
ecosystem can be predicted with accumulation of metals in organism. Mussels are
aquatic organism that capable to accumulate metals in their body. The purpose
of this research were to study pattern of Cd accumulation in body mussels
including mantle, gills, and kidneys. Mussels are exposed to Cd via water (20
µgL-1)for 24 days, followed by 12 days of depuration. On day 0, 1, 6, 12, 18,
24 (exposure time) and day 30, 36 (depuration time), mussels were dissected
into mantle, gills, and kidneys. Cd bioaccumulation in all organ was determined
by using Atomic Absorbance Spectrophotometer (AAS). The result showed that
pattern of Cd bioaccumulation attend to increase in all organs within exposure
time and attend to decrease within depuration time. The higest level of
accumulation being in kidney, followed by gillsand mantle.
