Abstract

The situation of soil contamination by heavy metals is very severe all over the world, and the traditional remediation technologies have many defects that are hard to be overcome. Recently, a nascent phytoremediation technology, in which plants was used to clean up the heavy metals in soil, was developed and hoped to solve the problem, and this technology was regarded as a cost-effective "green" technology. However, it needed much longer time than other traditional technologies, so, screening and breeding hyperaccumulators and increasing the bioavailability of heavy metals in soil became the key to improve the effect of intake and shorten the period of remediation. This paper reviewed some recent hot topics and their progresses in the field including: screening of hyperaccumulators, transgenic hyperaccumulators, and chelate-enhanced phytoremediation, et al; Some suggestions were also put forward for the work of our country in this field.

Key words： Heavy metals Phytoremediation Hyperaccumulator Transgenic plants Chelate
