Iron (Fe) is fourth most abundant element in the earth’s crust and is an essential nutrient for almost all organisms. Its solubility and availability are very changeable depending on soil pH and Eh and as a result, iron can be deficient under alkaline and oxidative conditions, whereas it can be present in excess under acidic and submerged conditions: both situations can generate serious nutriti...

soil scientists have developed different mathematical equations and indices to be able to quantify soil development and to organize soil data. the main objective of the present research was the comparison of different soil development indices (including forms and ratios of iron, magnetic susceptibility, color indices, and modified harden index) related to different soils located on kerman-baft ...

The effects of administration of aqueous extract of Alchornea laxiflora leaf at doses of 100, 200 and 300 mg/kg body weight on some antioxidant enzymes and lipid peroxidation in iron deficient albino rats were investigated. Thirty six albino rats (51.17±1.02g) were used for the study. Eight rats were fed on iron-sufficient diet while the remaining twenty eight were made iron-deficient by mainta...

A pot experiment was conducted to examine the effects of.various fertilizers on the dynamics of soil-borne DDTs and their subsequent impacts on DDTs uptake by a test plant. The results show that there was a significantly lower soil residual DDTs concentration in the iron-rich fertilizer-treated soil than in other fertilizer-treated soils. However, all the non-iron-rich fertilizers showed no sig...

Ethanol metabolism in hepatocytes is accompanied by release of a potent lipid chemoattractant for neutrophils. Production of the factor may initiate the inflammation associated with alcoholic hepatitis. In previous studies with a cytosol system from liver, production was blocked by iron chelators as well as by catalase and superoxide dismutase, suggesting the involvement of oxyradicals in forma...
