Abstract	Phytoextraction is a feasible method for eliminating heavy metals from contaminated soil. However, only a few plant species can hyperaccumulate toxic metals. We examined bioaccumulation patterns and the ecophysiological responses (i.e., photosynthetic pigments, total antioxidative capacity, and variations in antioxidant enzymes) in plants ofMonochoria korsakowi that were exposed to various concentrations of lead. Contents increased significantly when more lead was applied, with most of this metal being found in the roots. Biomass for each organ type decreased with higher lead concentrations. Chlorophyll a contents declined in proportion to lead amounts, whereas those of chlorophyllb were not significantly diminished. Carotenoid contents were not influenced by such treatment. Total antioxidant capacity in the leaf blades of treated plants increased greatly with higher lead concentrations. We conclude thatM. korsakowi could be used as a potential phytoremediator of heavy metals in contaminated soils.
