[Response of Cadmium in Soil-rice to Different Conditioners Based on Field Trials].

A plot experiment was carried out to assess the applicability of soil conditioners on Cd-polluted acidic paddy fields. The effects of five soil conditioners[Tianxiang 1 Hao (TX1), limestone (Li), silicon fertilizer, Nuodikang (NDK), and calcium magnesium phosphate fertilizer (CaMg-P)] on Cd accumulation and transport between contaminated soil and rice plants and rice yield on the land were analyzed. The results showed that compared with that under the control, other tested methods increased soil pH by 0.

[Characteristics and Planting Safety Assessment of As Content in Dryland Soil and Maize in Guizhou Province].

In order to understand the distribution characteristics of As content in dryland soils and maize seeds in Guizhou province and to evaluate the safety of maize cultivation, 468 natural soil samples, 1260 dryland surface soil samples, and 980 corresponding maize seed samples were systematically collected to determine their As content and basic physicochemical properties. The degree of contamination of the samples was evaluated by using the single-factor contamination index method. The results showed that: ① the range of (As) in dryland soil was 0.

[Characteristics of Antimony Migration and Transformation and Pollution Evaluation in a Soil-Crop System Around a Tin Mine in Hunan Province].

This study used 193 sets of farmland soil and agricultural product samples collected from around a tin mine in Hunan Province, China, to explore the antimony (Sb) content characteristics and pollution status of soil and agricultural products and to provide a scientific basis for the prevention and control of soil antimony pollution in antimony mining areas and the safe use of farmland. We analyzed the amount of antimony in the soil, basic physical and chemical properties, and antimony content in agricultural products; studied the characteristics of antimony migration and transformation in the soil-agricultural product system; and conducted safety assessments on soil and agricultural products. The results showed that the soil (Sb) in the central area of the mine, the southern area of the mine, the central township area, the urban-rural transfer area, and the northern area of the mine reached (2348±2165), (1298±884.
