During the last decade one of the most promising possibilities for the determination of microelements
by electrothermal atomic absorption spectrometry (ETAAS) in the environment, including seawater, was the use of a colloidal palladium modifier [10, 19].
can decrease the solder melting point because these microelements
can dissolve in the solid solution of SnBi20 and alter the space between tin and bismuth atoms, therefore altering the combination force between atoms.
When redox potentials are low, iron and manganese may solubilize and become toxic to plant roots, while some other microelements
may become unavailable to plants (Crawford, 1989).
Using the results of the geochemical research of REE together with the change of isotopic composition of carbon in the sedimentary cycle emphasizes the dynamics of the change of two different geochemical parameters during the catagenetic processes of OM and allow us to talk about the migration capabilities of microelements
(REE) and their accumulation together with hydrocarbons of oil and gas depending on the stage of organic matter transformation.
Other advantages of soil redox measurements are that they also relate to oxidation-reduction of soil microelements
(Marschner 1986; Setter and Waters 2003),
This is where takes place the exchange of microelements
, including REE with already formed bitumoids, but not at the expense of microelements

concentrations in OS usually do not exceed their respective average concentrations in the earth's crust (Table 3).

speeding up the biochemical reactions.

Presently, Chinese farmers have got used to applying N-P-K (nitrogen, phosphorus and potassium) fertilizers and microelement
fertilizers instead of straight fertilizers.
No complicated microelement
