In the laboratory condition, plants were exposed to prepared stock solution of copper, cadmium, and nickel metals with 1.0, 3.0, 5.0, and 7.0 ppm concentration metal solutions in certain periods (24, 48, 72, and 96 hours) and changing amount of accumulation of plants in depending on time and concentration was measured by atomic absorption spectrometer. As a result of data evaluation, it was found out that cadmium, cupper, and nickel materials were accumulated in different ratio by four aquatic plants in depending on time and concentration and the most accumulation for all metals was materialized on the fourth day. It is concluded that plants, submerged, accumulate more ratios of heavy metals in comparison with plants, free-floating and emergent; furthermore, rooted plants accumulate more ratios of heavy metals in comparison with rootedless plants. When the abilities of the heavy metal accumulation of the plants were compared, it is found that plant of G. densa accumulates the maximum ratio of heavy metals.

Bitkiler laboratuvar şartlarında bakır, kadmiyum ve nikel metallerinin stok solüsyonlarından (1000 ppm) 1.0, 3.0, 5.0 ve 7.0 ppm konsantrasyonlarında hazırlanan metal ...
