| Summary: | Ciputri upriver, Bandung, West Java has polluted by heavy metal Mn
coming from cow feces in the Cikidang village. Ligumia nasuta (Say, 1817) as an
aquatic organism usually use as bioaccumulator for metal, such as manganese.
The aim of research is to study Mn accumulation in the Eastern Pondmussel
Ligumia nasuta (Say, 1817). Mn contents in the water, extra pallial fluid, kidney,
hemolymph, gills, foot, digestive gland, mantle, and intestine were determined by
Atomic Absorbance Spectrophotometer (AAS). The mussels were collected at day
0, 1, and 6 after transplantation at 3 stations: before, near, and after pollution
sources. The results show that Mn2+ accumulation was in the digestive gland (25
mmol kg-1 ww) at station 2, day 6. The highest Mn accumulation was in the
digestive gland followed by the gills, mantle, kidney, foot, intestine, extra pallial
fluid, and hemolymph. At day 6, accumulation of Mn in the gills was 6.2 -fold of
control followed by the digestive gland (2.5-fold) and mantle (2.2-fold). It showed
that exposure of Mn to the mussels taken place via water.
Key word: Accumulation, Ligumia nasuta, Mn |
