The Accumulative Capacity of three plant species ( Eucaleptus camaldulensis L., Acacia cyanophylla L. and Ricinus communis L.) to cadmium

This study aims to compare the ability of three plant species (Eucaleptus camaldulensis L., Acacia cyanophylla L. and Ricinus communis L.) on the accumulation of cadmium (Cd) resulting from the different existing pollution sources in the study area (Abdul Qader Al Husseini Street - Latakia) especially resulting from traffic. The samples were collected from different parts (leaves, wood, bark) of the species mentioned in addition to samples of the soil, then the samples were processed and analyzed by atomic absorption spectrophotometer. The results showed a difference in the content of cadmium in the studied species, ranged between (0.25 mg/kg) and (0.42 mg/kg) dry weight, where the highest content in Ricinus wood (0.42 mg/kg) and then Eucalyptus wood (0.4 mg/kg) and minimum content in Acacia wood (0.32mg/kg). Ricinus and Acacia showed high ability to accumulate cadmium reaching Bioconcentration factor (BF=1.33) for Ricinus and (BF=1.13) for Acacia
