This study was used to measure the cellular uptake and subcellular distribution of copper in Thalassiosira weissflogii, coastal marine diatom, which are grown using free Cu ion concentrations that are characteristic of coastal waters. The study is broken down into an introduction, a discussion of materials and methods used, and a discussion of the results. Various tables and graphs accompany the article.

The accumulation and assimilation of mercury in marine diatoms are controlled by the presence of hydrophobic, neutrally charged mercury and methylmercury complexes in the cell cytoplasm of these organisms. Unlike organic mercury which binds to the cell membranes, methylmercury is easily accumulated in diatoms because it has higher assimilation efficiency and binds more efficiently to the cytoplasm. A bioaccumulation model to predict mercury accumulation and assimilation in fish is discussed.

THE PACKAGING OF ELEMENTS INTO rapidly sinking particles in the ocean is predominantly controlled by biological processes, including the production of zooplankton fecal pellets, which concentrates and encapsulates unassimilated elements [...]
