摘要：

Analytical data are presented for metal concentrations in aquatic bryophytes growing in the streams of a lead-zinc mining area in Dyfed, Wales. The highest concentrations of zinc (7023 ppm/dry weight) and of lead (16,000 ppm/dry weight) were recorded in plants growing nearest the mines, reflecting the extent of metal pollution in the water. The widespread occurrence of some species in these areas suggests a wide range of tolerance. The chemical form of zinc in stream water from the Frongoch mine, in which the zinc concentration was 58 ppm, was demonstrated to be Zn2+. © 1979.
