Samuel N. Luoma Ronald W. Harvey 1985 <p>Radioisotope labelling experiments with the estuarine clam, Macoma balthica, are described, in which a filter chamber device was used to separate solute metal uptake from uptake, of metals associated with suspended bacteria. Solute uptake contributed a majority of the 14-day total body burdens of 65Zn and 109Cd, whereas 57Co uptake largely resulted from ingestion of isotope-laden bacteria. In contrast to those for 109Cd and 65Zn, 57Co tissue distributions at 3 weeks differed significantly (p &lt; 0.05) between feeding and non-feeding clams (housed within filter chambers).&nbsp;</p> application/pdf 10.1007/BF00008711 en Springer Separation of solute and particulate vectors of heavy metal uptake in controlled suspension-feeding experiments with Macoma balthica article
