Transplanted aquatic mosses and freshwater mussels to investigate the trace metal contamination in the rivers Meurthe and Plaine, France.

摘要: Abstract Aquatic mosses Cinclidotus nigricans and freshwater mussels Dreissena polymorpha were transferred at eight monitoring sites along the rivers Meurthe Plaine (northeastern France) for a biological assessment of trace metal contamination. Autochthonous Fontinalis antipyretica collected end experiment. The major contaminants detected in organisms Cr, Ni, Pb Zn. A comparison between native introduced bryophytes showed that transfer technique was preferable to assess recent pollution situation. In case transplanted mosses, high initial levels strongly bound Zn prevented an accurate contamination with these two metals, since only little depuration occurred unpolluted sites. good qualitative agreement observed indications obtained from those mussels, suggesting both are suitable indicators purposes. quantitative di...
