Abstract

The purpose of this paper was to combine available peer-reviewed literature on PCB phytoremediation and make direct comparisons using ANCOVA statistics in order to determine if and what plants are presently a viable option for the remediation of PCB contaminated soils. Pumpkin (Curbita pepo cv Howden) consistently had the top root and shoot concentrations, as well as total plant accumulation. Their consistency shows that they can be reliable in the field and the most viable option. Tall fescue and sedge were also top contenders. Due to the small sample size for many plants and accounting for several confounding variables, very few of plant species and groups showed to be significantly better at PCB accumulation. PCB phytoremediation can be used in conjunction with other technologies or as an early action plan to begin decreasing PCB concentration levels as well as contain the PCBs, thereby preventing any release.
