Nickel Concentration in Soils - biocyclopedia

Nickel Concentration in Soils Nickel is abundant in the crust of the Earth, comprising about 3% of the composition of the earth. Nickel averages 50 mg Ni kg-1 in soils and commonly varies from 5 to 500 mg Ni kg-1 but ranges up to 24,000 to 53,000 mg Ni kg-1 in soil near metal refineries or in dried sewage sludge, respectively. Agricultural soils typically contain 3 to 1000 mg Ni kg-1, whereas ...
