Abstract

The aim of the present paper is the study of the influence of a polysaccharide (carboxymethylcellulose, CMC) on uptake by a target plant Lactuca sativa (LS) of selenium and some metals. LS was grown on a well characterized soil: such as, treated with 1.5 mgkg-1 Se(IV) only and with two levels of CMC (3 and 30 mgkg-1). Similar experiments were carried out by using Se(VI) instead of Se(IV). Uptake was evaluated through the quantification of total content of Se in dried leaves and roots by a suitable technique (graphite furnace atomic absorption spectrophotometry, instrumental neutron activation analysis and differential pulse cathodic stripping voltammetry). Results evidenced as the uptake of selenium was dependent on the form of selenium added to the soil: Se(VI) is accumulated much more then Se(IV) according to its lower toxicity and higher mobility. The simultaneous presence of CMC led to a lower selenium uptake in leaves, whereas no clear influence was evidenced in roots. Furthermore, the presence of CMC influenced also the mobility process (soil→plant) of several other metals: a lower content of them was detected in plants when CMC was present in the soil. © 2003 Elsevier Science B.V.
