plant-aid remediation of hydrocarbon-contaminated sites

Phytoremediation is an emerging green technology that uses plants and their associated microbes to remediate different environments contaminated with various pollutants. phytoremediation, as an effective soil remediation technology, has gained popularity in the past ten years both in developed and developing countries. the main goal of the current article is to improve the understanding of phytoremediation of organic pollutants with emphasis on hydrocarbons. to design phytoremediation systems and also enhancement of their efficiency, either in laboratory or in field experiments, there is a serious need for better knowledge of phytoremediation mechanisms and also of factors affecting phytoremediation. in addition to phytoremediation applications, advantages, and limitations, its mechanisms and related new developments have been discussed in this article.
