متن کاملIodine-129 and iodine-127 in seawater of the North Sea and precipitation from northern Germany
Atmospheric nuclear weapons tests, nuclear accidents, and emissions from reprocessing plants have changed the natural abundances of I (T1/2=15.7 Ma) in a sustainable manner. Mainly as a consequence of the I releases from the European reprocessing plants, I is in disequilibrium in all environmental compartments of the Western Europe. Surface water from the North Sea and the English Channel, whic...
متن کاملIodine accumulation in sea urchin larvae is dependent on peroxide.
Iodine has many important biological functions and its concentrations vary with the environment. Recent research has provided novel insights into iodine uptake mechanisms in marine bacteria and kelp through hydrogen peroxide-dependent diffusion (PDD). This mechanism is distinct from sodium-dependent mechanisms known from vertebrates. In vertebrates, iodine accumulates in the thyroid gland by th...
متن کاملDecomposition of Organic Matter in Sea Water by Bacteria: I. Bacterial Multiplication in Stored Sea Water.
The organic matter in the sea is unevenly distributed between the living plant and animal population, the suspended detritus, the organic matter in the sea bottom, and that present in the water in true and in colloidal solution. The living forms and the detritus make up only a small part of the total organic matter in the sea; the ratio between the organic matter in solution and that present in...
