Biosorption characteristics of Cadmium from environment by one-year old seedlings of Acer velutinum

Abstract

Background and Aims: Heavy metals are elements with high atomic weight and could be harmful for living organisms at higher concentrations. Cadmium is among these metals and may result in various health problems forhuman. The ability of Acer Velutinum in bioremediation of cadmium was considered in the present study.Materials and Methods: One-year old seedlings of Acer Velutinum were provided from Department of Natural Resources making arrangements well in advance. Cadmium chloride solutions were prepared with different concentrations of 0, 10, 20 and 40 mg/L and consequently were added into the soil. The seedlings were planted inpots and their aerial organs (stems and leaves) as well as their roots were separated three month after. The results were then analyzed using Danken and ANOVA tests.Results: The maximum amount of cadmium accumulation in aerial organs, root and soil was 9.67, 60.61 and 12.44 mg/kg, respectively. Similarly, the respective lowest level of cadmium accumulation in aerial organs, root and soil was 6.05, 2.3 and 0.1mg/kg. The least amount of aerial organs (4.45 g) and root (1.25 g) dry weights wereoccurred at 40 mg Ca/L, and the most values of respectively 9.02 and 3.95 g was observed at pristine control pot.Conclusion: Acer Velutinum species is considered as appropriate for bioremediation of soils contaminated by cadmium.Keywords: Cadmium, Adsorption, Heavy metals, Phytoremediation, Acer Velutinu
