Increasing concentration of heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) in the soil may impose a serious threat to living organisms due to their toxicity and the ability to accumulate in plant tissues. The present review focuses on the phylogenetic relationships, sources, biotransformation and accumulation potential of hyperaccumulators for the priority HMs and PAHs. This review provides an opportunity to reveal the role of hyperaccumulators in removal of HMs and PAHs from soils, to understand the relationships between pollutants and their influence on the environment and to find potential plant species for soil remediation. The phylogenetic analysis results showed that the hyperaccumulators of some chemicals (Co, Cu, Mn, Ni, Zn, Cd) are clustered on the evolutionary tree and that the ability to hyperaccumulate different pollutants can be correlated either positively (Cd-Zn, Pb-Zn, Co-Cu, Cd-Pb) or negatively (Cu-PAHs, Co-Cd, Co-PAHs, Ni-PAHs, Cu-Ni, Mn-PAHs). Further research needs to be extended on the focus of commercializing the techniques including the native hyperaccumulators to remediate the highly contaminated soils.

重金属和多环芳烃的超蓄积植物种类的系统发育分析。

土壤中重金属（HMs）和多环芳烃（PAHs）的浓度不断增加，由于它们的毒性和在植物组织中积累的能力，可能对生物造成严重威胁。目前的审查集中在系统发育关系，来源，生物转化和积累潜力的优先HMs和PAHs。这项综述提供了一个机会，揭示了超蓄积剂在从土壤中去除HM和PAH的作用，了解污染物之间的关系及其对环境的影响，并找到了潜在的土壤修复植物。系统发育分析结果表明，某些化学物质（钴，铜，锰，镍，锌，Cd）聚集在进化树上，并且不同污染物超积累的能力可以正相关（Cd-Zn，Pb-Zn，Co-Cu，Cd-Pb）或负相关（Cu-PAHs，Co-Cd，Co -PAHs，Ni-PAHs，Cu-Ni，Mn-PAHs）。还需要将技术商业化的重点扩展到进一步的研究上，这些技术包括用于修复高污染土壤的本地超级蓄能器。
