Abstract

Lemna minor is frequently used in bioremediation processes to remove nutrients and contaminants from waste water. In this work the response of L. minor to treatments with lanthanum nitrate and with a mix of several light rare earth elements (REE) nitrates was investigated. Preliminary results indicate that L. minor shows an overall good tolerance to the presence of REE in the media. Toxic effects were observed after prolonged exposition to high concentration of REE. An increase in ascorbate and glutathione content as well as in ascorbate peroxidase, dehy-droascorbate reductase and ascorbate free radical (AFR) reductase activity was observed in treated plants. © 2007 Taylor and Francis Group, LLC.
