Zinc in soils, water and food crops - ScienceDirect
2018-9-1 1. Introduction. Zinc (Zn) plays a substantial role in many biological processes and is an essential trace element for proper growth and reproduction of plants, and health of animals and humans; it has also been reported to cause contamination of soil, water, and food chains [, , ].In human beings Zn deficiency is associated to diet quality, exacerbated by Zn-deficient soils [4,5].

2014-12-4 Abstract. The immobilization of toxic metals in soils using amendments is a cost-effective remediation technique for contaminated soils. Therefore, this study aimed to assess the efficiency of various amendments to immobilize nickel (Ni) and zinc (Zn) in soil and reduce their phytoavailability.

These soils were acidified over thousands of years by inputs of acids from atmospheric sources (carbonic, sulfuric, and nitric acid), the decay of plant and animal residues, and removal of basic cations by the natural processes of leaching. If our native soils are not limed (basic), the pH is often in the 4.5 to 5.5 range.

Assessment of copper, cobalt and zinc contaminations
The infiltration of heavy metals into soils through steel plant production processes is one of the most important soil pollution sources. The aim of this study was to determine copper (Cu), cobalt (Co), and zinc (Zn) concentrations in soil and plant shoots around the Esfahan steel company (ESC). In this study, we separated 17 zones based on soil maps and marked 54 points for soil sampling.

Effects of calcium on nickel tolerance and
Nickel (Ni) phytoextraction using hyperaccumulator plant species to accumulate Ni from mineralized and contaminated soils rich in Ni is undergoing commercial development. Serpentinite derived soils have a very low ratio of Ca/Mg among soils due the nature of the parent rock. In crop plants, soil Ca reduces Ni uptake and phytotoxicity, so it is possible that the low Ca of serpentine soils could ...
