متن کاملA Primer on Trace Metal- Sediment Chemistry
In most aquatic systems, concentrations of trace metals in suspended sediment and the top few centimeters of bottom sediment are far greater than concentrations of trace metals dissolved in the water column. Consequently, the distribution, transport, and availability of these constituents can not be intelligently evaluated, nor can their environmental impact be determined or predicted solely th...
متن کاملTrace metal pollution in the Mediterranean Sea
In the Mediterranean Sea, the distribution of dissolved zinc, copper, lead and cadmium is primarily controlled by marine circulation, surface source dynamics and biological new production. We show that the present relatively high content of these metals in the surface layer is due to non-steady-state cycles as a result of source increases probably following increases in industrial, agricultural...
متن کاملTrace-metal analysis with separation methods
This broad overview covers the use of gas and liquid chromatography as well as capillary electrophoresis for the determination of metal ions and metalcontaining species, such as organometallic compounds or metalloproteins. We pay particular attention to the latest developments and consider the features of the various detection techniques and applications of the different methods. a 2005 Elsevie...
