USE OF THE FRESH WATER PLANTS ZANNICHELLIA PALUSTRIS AND MYRIOPHYLLUM ACUATIUM FOR BIOMONITORING OF Cd, Pb, AND Cu IN ANDEN RIVERS OF CHILE
The species Zannichellia palustris and Myriophyllum acuatium, collected along the Loa River basin, North Chile, were chosen as possible bioindicators for Cd, Pb, and Cu. These species have a cosmopolitan distribution and can survive very sudden and large fluctuations in salinity. They are widely spr...
