Analytical Methods for Trace Metals: Training Manual
B Radiation Buffers For measurements of alkaline earth metals (sodium, potassium, calcium, magnesium) radiation buffers are pre- pared as solutions saturated with regard to each metal, respectively. A potassium buffer, for example, is pre- pared by saturating distilled water with sodium, calcium, and magnesium chloride.

Trends in Cyclopentadienyl−Main-Group-Metal Bonding …
In contrast to transition metals (TMs), main-group metals (MMs) show a bewildering variety of bonding arrangements to cyclopentadienyl (Cp) groups, including electron-precise, electron-excess, and electron-deficient structures. From a theoretical examination of a large nuer of representative species, and a comparison with experimental structures, we have deduced three factors which coine

Heavy metals in food crops: Health risks, fate, …
1/4/2019· Metal stress tolerance mechanisms and metal fate in crop plants The toxicity of heavy metals in crop plants is minimized by the plants'' ability to avoid (e.g., exocytosis) or tolerate stress. Avoidance is a basic strategy used to prevent heavy metals in the roots from entering the shoots and leaves by neutralizing their toxic effects in root cells ( Krzeslowska et al., 2010 ).
