摘要：
Transplants of the aquatic moss Fontinalis antipyretica Hedw. were used to assess the contamination of an industrial effluent discharge on a river located in south Portugal. The sampling program was run for 2 years, using a newly developed transplant device in ten stations. and the elements analysed were Cu, Zn, Pb, Fe, Ni, Ca, K, and Mg. An increase of water contamination by Cu, Zn was detected. and to a lesser extent, Pb. The increase was verified in the extra and intracellular moss fraction, especially for soluble Cu in the first 4 km after the discharge point, and also for particulate metal at the first station after the discharge. The effects of metal contamination Could be related to changes in the intracellular concentrations of Mg, indicating possible stress effects. (c) 2005 Elsevier Ltd. All rights reserved.
