Producing nutritious and safe foods sufficiently and sustainably is the ultimate goal of modern agriculture. Past efforts have focused on increasing crop yields, but enhancing the concentrations of mineral micronutrients has become an urgent task because about half of the world population suffers from the malnutrition of iron, zinc, and selenium. Biofortification of these trace elements can be ...

The mineral ilmenite is analysed by LA-ICP-MS for elemental and U–Pb isotopic compositions. A methodology presented accurate results using the rutile ages basaltic reference materials major trace elements.

Deficiencies of phosphorus, copper, cobalt and selenium are the main mineral deficiencies in southeastern Australia that are likely to affect lactation, growth, carcass composition and wool production of grazing livestock being compared in genetic improvement programs. Genetic variation in mineral nutrition has been recognized from differences in the incidence of mineral disorders between breed...

Nutrients are defined as not only having nutritive values of participating in the metabolism and building the structures of cells but also being safe for human body. Nutrients are divided into two types, macronutrient and micronutrient, according to the proportion of the human body. Commonly, micronutrients include trace elements (trace mineral) and vitamins (complex organic molecules). It is d...

[1] The global chemical transport model GEOS‐Chem, implemented with a dust‐iron dissolution scheme, was used to analyze the magnitude and spatial distribution of mineral dust and soluble‐iron (sol‐Fe) deposition to the South Atlantic Ocean (SAO). The comparison of model results with remotely sensed data shows that GEOS‐Chem can capture dust source regions in Patagonia and characterize the tempo...

BACKGROUND Many plants with antidiabetic properties probably act in part through their content of fibre, vitamins, bioactive or mineral content OBJECTIVES This study investigated the mineral, proximate, phytochemical compositions and hypoglycaemic effect of Commelina africana and Ageratum conyzoides extracts in diabetic rats, and the likely relationship between this property and the mineral, ...
