植物修复是利用植物对有毒物质污染场地进行修复的一种策略，受到越来越多的关注。本文介绍了植物修复的方法和目前的研究领域。人们对去除金属的兴趣最大，主要是因为对植物如何处理油和清洁液等有机污染物知之甚少。正在调查的地点包括锌和铅污染的废弃矿山;铅和镉的军事地点;铜，汞和铅的城市废物倾倒场;污水污泥倾倒场。热带植物似乎在该领域占主导地位，但其他植物也显示出希望。
Phytoremediation, a strategy of using plants to remediate site contaminated with toxic materials, is growing in interest. This article describes phytoremediation methods and current research in the field. Most of the active interest is in removing metals mainly because much less is known about how plants handle organic contaminants such as oils and cleaning fluids. Sites being investigated include abandoned mines with zinc and lead contamination; military sites with lead and cadmium; municipal waste dumps with copper, mercury, and lead; sewage sludge dump sites. Tropical plans seem to predominate in the field but other plants are also showing promise.
