Accumulation of aluminum and iron by bryophytes in streams affected by acid-mine drainage.

Abstract

Accumulation of two heavy metals (Al and Fe) by bryophytes was examined in a northern Pennsylvania stream system affected by acid-mine drainage. Four sites within one watershed were selected on the basis of their pH and dissolved metal concentrations. Significant differences among sites were found with regard to bioaccumulation of Al and Fe. A negative… (More)
