ABSTRACT- There is a continuing interest in the clean-up of contaminated sites by biological means, because of the improvements in sustainability that they offer. One potential tool in this strategy is phytoremediation. To date there have been a number of studies which have indicated that certain plant orders have the ability to accumulate heavy metals. In one study three orders; the Malpighales, Brassicales and Asterales were found to contain c.85% of the hyperaccumulating taxa. These taxonomic approaches can provide important information when choosing appropriate plant species for a given contaminant and ecological situation. Furthermore such approaches will become more useful as plant classification becomes more informed by genetic information, as this is more likely to provide information on an individual species ability to produce enzymes or chelators which may be important in metal accumulation or organic pollutant degradation. The paper will present our initial findings when using phylogentic screening approaches for those plants which may be beneficial for the phytoremediation of organic pollutants.
