Daftar Isi:
- Cadmium (Cd) is one of important heavy metal in textile, plastic, and battery industries, and electroplating, Cd is non-essensial metals, non-degradable, and toxic at low concentration. Cd polution in fr eshwater ecosystem from the usage of Cd in many industrial activities can interfere biological system of aquatic animals. Mussels are aquatic organism which is capable to accumulate metals in their body. Evaluation of heavy metals in freshwater ecosystem can be determined by accumulation of metals in organism. Accumulation pattern in organism can be predicted by toxicokinetic models. The aim of this research was to study toxicokinetics of Cd in freshwater mussel Elongaria orientalis. Mussels were exposed to Cd via water (20 Âμg L -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, kidneys, intestine, digestive gland, foot, and adductor muscle. Haemolymph (HML) was withdrawn from posterior adductor and extra pallial fluid (EPF) was withdrawn between mantle and inner shell. Cd levels in all organs and body fluids were determined by using Atomic Absorbance Spectrophotometer (AAS). The results show that Cd levels increased in all body compartemens E. orientalis during 24 days exposure. The higest level of Cd found in the kidneys and followed by the gills. The pattern of Cd bioaccumulation attend to increase in all organs during exposure time and decrease during depuration time. The results indicate that E. orientalis has capability to uptake Cd from surrounding environments and to eliminate Cd from their body. Distribution and accumulation Cd in depend on concentration, exposure pathway, and time exposure. Cd accumulation also tissue specific.
