Soil heavy metal pollution can cause a change in the composition, structure and functions of soil, and then harmful substances or breakdown products gradually accumulated in the soil, through the “soil, plants, human body” system indirect absorbed by human body, and endanger human body health.
Repair of heavy metal contaminated soil by adopting the physical chemistry of replace with out-soil, leaching technology.
Adjust the planting structure in pollution area.
Therefore, by adjusting the pollution area planting structure can effectively reduce the heavy metal pollution of food.

In that way, a partial order of the 2:17 structure can be described.
This structure is derived from the CaCu5 structure and was identified by K.H.J.
In the following it will be shown, that this structure can be transformed into a larger rhombohedral unit cell, which can be denoted as the disordered 2:17 structure.
Fig.1 shows the calculated X-ray patterns of variably partially ordered m-Sm2Fe17 structures in comparison with the completely disordered rhombohedral structure (curve (a)) and the completely ordered Th2Zn17 structure (curve (d)).

Research on the Stability and Content Detection of Anthocyanin of Black Peanuts Clothing Yue Shao1,a, Xianglong Liu2,b, Hong Shao*2,c, Yunjiao Li2 1College of Chemistry and chemical engineering and Food Safety, Bohai University, Jinzhou 121000, China; 2School of Environment and Safety Engineering, Shenyang University of Chemical Technology, Shenyang 110142, China) ashaoyue0416@163.com, bwestdragon_1@163.com, chj8983@163.com Keywords: Black peanut clothing; Anthocyanin; Content; Stability Abstract.
Purple precipitation generates when α-naphthol meets Fe3+, however the solution turns green and no sediment occurs when β-naphthol meets Fe3+. [16] Therefore, structure of β-naphthol is supposed to exist mainly in the material that we use, while α-naphthol structure exists in the black peanut produced in Hunan Agricultural University experimental base.

With the elongation of aging time to 4 h in Fig. 1c, Bi2S3 nuclei further developed into bamboo shaped structure nanorods with average diameters of about 30 nm.
Under the structural direction of the chain-structured PEG, Bi2S3 nuclei were being delivered bit by bit in situ and formed preferential growth.
Conclusions In summary, a self-assembly approach has successfully fabricated the Bi2S3 nanorods by sonochemical aqueous solution using PEG as structure-directing agent.

Under such extreme conditions, Various novel chemical reactions and physical changes occurred, and numerous nano-structured materials such as metals, alloys, oxides and biomaterials had been synthesized by using high-intensive ultrasound[9,10].
The structure of the hydrolysates is related with the pH value of hydrolysis medium.
This polymer is compatible in structure with rutile only[11,12].
Then nuclei, which can form nanometer particles with structure of rutile, would be obtained when the concentration of octameic achieved supersataration.
