Influence of Nitrogen Nutrients on Hyperaccumulation of <i>Sedum alfredii </i>Hance under Complex Heavy Metals Stress

Abstract

Heavy metals contamination is a major environmental issue, and phytoremediation is a promising, environmentally friendly alternative to conventional cleanup techniques for heavy metal contaminated sites. this paper is intended to explore the influence of different nitrogen nutrient levels on hyperaccumulation of sedum alfredii, a promising hyperaccumulating plant species for the phytoremediation exposured to complex contaminations. The obtained results indicated that the proper increasing of nutriogen nutrient levels enhanced the accumulation capacity of complex heavy metals in sedum alfredii hance.
