Abstract: Mercury (Hg) is considered as a global extreme destructive pollutant. Now, the problem of contaminated soil was more and more serious because of industry development and mercury mine exploitation, which took painful results not only to environment, but also to mankind. So, this problem has been concerned by many scientists. Phytoremediation of mercury-contaminated soil had many advantages, including low cost and environment-friendly. This paper introduced the technology of phytoremediation in mercury contaminated sites, especially, the application of transgenic technology in mercury contaminated soil. The significance of transgenic technology in mercury contaminated soil was also discussed.
