The Advance and applied prospect of phytoremediation in heavy metal contamination soil

Soil contamination especially heavy metal pollution was a severe problem.Many gove rnments and scholars were paying much attention to the remediation of heavy metal contamination in soil.Phytoremediation,a green,safe technology,was a hotspot with the properties of efficiency,economy and ecology harmony.The conception,principle,research dynamics advantages and applied prospects were reviewed systematicly.Some applied examples at domestic and abroad were cited,what's more,some questions in the air,future developments and a few previews were put forward.
