Abstract: | In this study, Groenlandia densa (L.) Fourr. (opposite-leaved pondweed), was exposed to prepared stock solution of cadmium and copper with 1.0, 3.0, 5.0 and
7.0 mg L−1 concentration in certain periods (24, 48, 72 and 96 h) and changing amount of accumulation of plants in depending on time
and concentration was measured by atomic absorption spectrophotometer. The results show that under experimental conditions,
G. densa (L.) Fourr. proved to be a good accumulator of Cd and Cu. Removal of the metals from solution was fast in the first 4 days.
The accumulation of Cd and Cu increased with the initial concentration and also with time. The highest concentrations of each
trace element accumulated in opposite-leaved pondweed tissues were 1,955 μg Cd g−1, 6,135 μg Cu g−1 after 4 days. The maximum values of bioconcentration factor (BCF) were found for Cd and Cu 724 and 1,669, respectively. BCF
values for Cd and Cu increased with time. |
