| Abstract | ||
| The mollusca have bioaccumulation ability for trace elements in body more than surrounding media therefore Snail Bellamya bengalensis was exploit as bioindicator for pollution in four stations within shatt Al Arab bank by six trace elements ( Fe, Co, pb, Cd, Cu and Ni) from winter 2008 to winter 2009. A flame atomic absorption spectrophotometer was used to measure the concentration of the trace elements. Bioaccumulation average of trace elements was high reach 2774.260, 28.813, 26.217, 10.362, 179.592and 68.688 µg/g dry wet respectively. The same trace elements concentrate in sediment was investigated, the concentrations were between 2214.12- 5766.34, 12.67-79.28, 24.55-86.58, 0.0456- 18.18, 20.81- 64.58 and 0.8434 - 114.54 µg/g dry wet respectively while the concentration average in water was 9338.19, 234.155, 352.693, 149.28, 64.647 and 323.401 µg/l respectively. Biological concentration factor was investigate and it was high for Cd, Cu and Ni. Present study showed ability of Snail Bellamya bengalensis to used as good bioindicator for pollution by trace elements. | ||
