Abstract

The concentration of nickel and cadmium in Typha sp. and Eichornia crassipes and the parts of the macrophytes which concentrate the highest level of heavy metal were studied. The concentration of the heavy metals in macrophytes and various plant parts of macrophytes were determined using the atomic absorption spectroscopy (AAS). The average concentration of nickel in Typha sp. was 184.0mg/100g dry wt and in E. crassipes was 80.7mg/100g dry wt. The average concentration of cadmium in Typha sp. was 8 1.4mg/100g dry wt and in E. crassipes was 25 .6mg/100g dry wt. The average concentration of nickel in Typha sp. roots was 223.8 mg/l00g dry wt and in its leaves was 184.5 mg/100g dry wt, and in E. crassipes roots was 78.0 mg/100g dry wt and in its leaves was 64.0 mg/l00g dry wt. The average concentration of cadmium in Typha sp. roots was 90.5 mg/100g dry wt and in its leaves was 69.5 mg/l0Og dry wt, and in E. crassipes roots was 28.9 mg/100g dry wt and its leaves was 5.4 mg/100g dry wt. In summary, Typha sp. accumulated higher nickel and cadmium concentration than Eichornia crassipes. Typha sp. roots accumulated higher nickel and cadmium concentration than its leaves and E. crassipes roots and its leaves.
