Taylor, F. G.

The environs of an industrial plant in east Tennessee (USA) have been exposed to hexavalent chromium (Cr/sup +6/) deposition for over three decades. The behavior of this metal was investigated in a series of studies designed to determine its bioavailability through interception, retention, and incorporation in plants by foliar and root uptake. In this contribution, condensed summaries of research from field and controlled environment studies are reviewed to determine how they pertain to transfers between ecosystem compartments and to ascertain the storage of the contaminant in a grassland ecosystem following years of continuous deposition.
