摘要
硒污染已成为全球性的环境问题,严重威胁人类健康和环境安全。本文概述了环境硒污染植物修复技术的研究进展,包括硒富集植物的应用、富集硒的机理及生物技术对它们的改造。指出了当前研究在硒富集植物富集机理及田间应用时的不足;并展望了今后如何进一步寻找和使用生物技术培育硒超富集植物、探求富集机理和田间试验。
Selenium pollution now is a global environmental problem with harmful effect on human health. This article has summarized advances of the research on the phytoremediation techniques of the selenium polluted environment, including the application of Se accumulators, the mechanism of Se accumulation and the modification of Se accumulators into Se hyperaccumulators with biotechnology. It has pointed out that there are some deficiencies in the present study on the mechanism and the application of Se phytoremediation and also has given some prospective views about the researches on those aspects in the future.
