生物谷報道：重金屬是人們非常關心的環(huán)境污染物,。 由于人類活動,，例如采礦和金屬礦石的冶煉，電鍍,， 能源和燃料生產(chǎn),，肥料和殺蟲劑應用,，等等,，金屬污染變成今天最嚴重的環(huán)境問題之一。植物修復技術是新興的最有希望的解除重金屬污染的方法之一,。就是利用一類特殊的具有超積累重金屬的植物,，富集重金屬于植物地上部，然后采用集中填埋或者重新冶煉金屬,，改良環(huán)境的一種方式,。目前由于對重金屬富集的分子機理尚不清楚極大限制了植物修復技術的應用,。

    Due to their immutable nature, metals are a group of pollutants of much concern. As a result of human activities such as mining and smelting of metalliferous ores, electroplating, gas exhaust, energy and fuel production, fertilizer and pesticide application, etc., metal pollution has become one of the most serious environmental problems today. Phytoremediation, an emerging cost-effective, non-intrusive, and aesthetically pleasing technology, that uses the remarkable ability of plants to concentrate elements and compounds from the environment and to metabolize various molecules in their tissues, appears very promising for the removal of pollutants from the environment. Within this field of phytoremediation, the utilization of plants to transport and concentrate metals from the soil into the harvestable parts of roots and aboveground
shoots, i.e., phytoextraction, may be, at present, approaching commercialization. Improvement of the capacity of plants to tolerate and accumulate metals by genetic engineering should open up new possibilities for phytoremediation. The lack of understanding pertaining to metal uptake and translocation mechanisms, enhancement amendments, and external effects of phytoremediation is hindering its full scale application. Due to its great potential as a viable alternative to traditional contaminated land remediation methods, phytoremediation is currently an exciting area of active research.
