title: Multielement analysis of metal-binding proteins in cytosol fractions.
abstract: The distribution of 24 elements among the cytosol protein fractions was determined for specimens of the bivalve mollusc Macoma balthica obtained from three estuarine locations subject to varying levels of metal pollution and on specimens of Rangia cuneata from three areas subject to varying degrees of thermal pollution. Of the 24 elements examined 15 occurred at levels above detection limits and in association with one or more of four distinct protein fractions. Levels of Ag and Cu associated with high molecular weight proteins and with "metallothionein-like" proteins permitted identification of those Macoma balthica specimens exposed to the greatest degree of metal stress.
