A Comparison Of Bioaccumulation And Digestive Enzyme Solubilization Of Copper In Two Species Of Sea Cucumbers With Different Feeding Habits., John W. Bundridge
Electronic Theses and Dissertations
The mode of feeding exhibited by different organisms may influence the form or quantity of copper that is bioaccumulated. This hypothesis has been tested by exposing 2 species of sea cucumbers, Pentacta anceps and Stichopus chloronotus, which possess different feeding modes, to varying concentrations of copper.
The digestive tract and body wall were dissected and analyzed for copper concentration using atomic absorption spectroscopy. A trend was present, exhibiting a small dose dependent curve. The results did not show a significant difference between species or treatments. This study indicates that feeding mode may influence the amount of copper accumulated but …
