  <dc:description>&lt;div class="hlFld-Abstract"&gt;&lt;div id="abstractBox"&gt;&lt;p class="articleBody_abstractText"&gt;An 18-day microcosm study was conducted to evaluate the influence of acid volatile sulfides (AVS) and metal additions on bioaccumulation from sediments of Cd, Ni, and Zn in two clams (&lt;i&gt;Macoma balthica&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Potamocorbula amurensis&lt;/i&gt;) and three marine polychaetes (&lt;i&gt;Neanthes arenaceodentata, Heteromastus filiformis,&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Spiophanes missionensis&lt;/i&gt;). Manipulation of AVS by oxidation of naturally anoxic sediments allowed use of metal concentrations typical of nature and evaluation of processes important to chronic metal exposure. A vertical sediment column similar to that often found in nature was used to facilitate realistic biological behavior. Results showed that AVS or porewater (PW) metals controlled bioaccumulation in only 2 of 15 metal-animal combinations. Bioaccumulation of all three metals by the bivalves was related significantly to metal concentrations extracted from sediments (SEM) but not to [SEM − AVS] or PW metals. SEM predominantly influenced bioaccumulation of Ni and Zn in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;N. arenaceodentata&lt;/i&gt;, but Cd bioaccumulation followed PW Cd concentrations. SEM controlled tissue concentrations of all three metals in&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;H. filiformis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;S. missionensis&lt;/i&gt;, with minor influences from metal-sulfide chemistry. Significant bioaccumulation occurred when SEM was only a small fraction of AVS in several treatments. Three factors appeared to contribute to the differences between these bioaccumulation results and the results from toxicity tests reported previously:  differences in experimental design, dietary uptake, and biological attributes of the species, including mode and depth of feeding.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
