EFEK KADMIUM (Cd) PADA KANDUNGAN KALSIUM (Ca) INSANG dan GINJAL KERANG AIR TAWAR Elongaria orientalis (Lea, 1840)
Abstract: Cadmium (Cd) is
wide-spread metals in aquatic ecosystem. It has long half-time and toxic in
body. Aquatic animals uptake Cd through gills and digestive trac.Cd in body
interfere Cd homeostatis in cell. Ca is an important component in shell
formation. The purpose of this research were to knowthe effects of Cd exposure
on calcium level of gills and kidney freshwater mussel Elongaria orientalis.
Mussels are exposed Cd via water (20 µgL-1)for 24 days and 12 days of
depuration. Mussels were diseeceted into gills and kidneys on day 0, 1, 6, 12,
18, 24 (exposure time) and day 30, 36 (depuration time). Ca concentration was
determined by using Atomic Absorbance Spectrophotometer (AAS). The result
showed that Caconcentrationin gills and kidneys increase along exposure
time.During depuration time, Ca concentration in both of organs intend to
decrease.
