The accumulation of a trace metal in rice grain is not only affected by the total concentration of the soil trace metal, but also by crop variety and related soil properties, such as soil pH, soil organic matter (SOM) and so on. However, these factors were seldom considered in previous studies on mapping the pollution risk of trace metals in paddy soil at a regional scale. In this study, the sp...

the role played by soil constituents in governing temporal trends of metal mobility in calcareousmediterranean soils deserves special attention due to the particular soil and climate characteristics. reactionsoccurring during the aging modify the metal mobility over time, and the rate of metal application and type ofsoil can be decisive in the outcome of aging reactions in soils. the aim of the...

Heavy metal pollutions of soil is one of the serious problems in the mining tailing areas, therefore, it is significant to estimate heavy metal of soil in the mining tailing areas. This research take Jinduicheng Mo mining tailings, Huaxian, Shaanxi Province as the study area. A total number of 288 soil samples collected at the mining tailing areas. And the heavy metal concentrations of Pb in so...

Leaching using EDTA applied to a Pb, Zn and Cd polluted soil significantly reduced soil metal concentrations and the pool of metals in labile soil fractions. Metal mobility (Toxicity Characteristic Leaching Procedure), phytoavailability (diethylenetriaminepentaacetic acid extraction) and human oral-bioavailability (Physiologically Based Extraction Test) were reduced by 85-92%, 68-91% and 88-95%...

Four types of soil (red, yellow, cinnamon, and paddy soil) from China were used to conduct experiments in pots to study the influence of humic acid (humic acid (HA) and fulvic acid (FA)) on the accumulation of lead (Pb) and cadmium (Cd) in tobacco leaves. In non-polluted soils, the tobacco leaf uptake of Cd was dramatically influenced by the total soil metal concentration and soil properties, w...

Today, soil pollution with heavy metals is a major environmental concern across the world. Phytoremediation is defined as a technique through which plants are able to absorb contaminants and potently recover the soil that is polluted by heavy metals. The present study aimed to investigate the level of nickel concentration in the roots, stems, and leaves of sunflower, as well as the mobility of ...

The present study aimed to identify the effect of heavy metal concentration and soil pH on the abundance of the selected soil microorganisms within ArcelorMittal Poland steelworks, Cracow. The analysis included 20 soil samples, where the concentration of Fe, Zn, Cd, Pb, Ni, Cu, Mn, Cr and soil pH were evaluated together with the number of mesophilic bacteria, fungi, Actinomycetes and Azotobacte...

A field study was conducted at three sites (S1-S3) of 500m longitudinal transect along the drain, where soil was irrigated by toxic metal rich brass and electroplating industrial effluent in suburban area of Moradabad, India. Spatial and seasonal variations of total heavy metal content in soil and their effect on physico-chemical and biological properties were studied in soil samples taken from...
