The bivalves, originating from a relatively polluted marine area of Greece (Saronicos Gulf), were exposed to 0.5 mg Cd L–1 seawater (4.4 mol Cd L–1 seawater) for 5, 10, 15, and 20 days. Control animals were kept in metal-free seawater as well. Three or four different parts of the organisms (gills, mantle, body, digestive system) were examined for the bioaccumulation of Cd, as well as the levels of three biomarkers (metallothioneins, acetylcholinesterase, lipid peroxidation). A depuration experiment was also carried out. During the experiment, the initial levels of Cd in the control animal tissues either decreased or remained constant and low. The organisms exhibited different behavior regarding Cd bioconcentration and biomarker responses as well as tissue distribution of Cd. After the depuration period, significant amounts of Cd remained in the organisms’ tissues, much higher than the respective levels in control animals. 16 pp. LOMv1.0 creator LOMv1.0 publisher LOMv1.0 Scientific Coordinator LOMv1.0 Project Executing Organisation 2014-05 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Bioconcentration Cadmium Callista chione Environmental chemistry IUPAC Congress-44 Environmental Chemistry Mytilus galloprovincialis Toxicology Trace elements Venus verrucosa http://www.degruyter.com/view/j/pac.2014.86.issue-7/pac-2014-0110/pac-2014-0110.xml 2327119 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/3223/2/3223_1.24_%ce%94%ce%97%ce%9c_28_5_14.pdf In collection of invited papers based on presentations on the Environmental Chemistry theme at the 44 th IUPAC Congress, Istanbul, Turkey, 11–16 August 2013.
