With the aid of more sensitive instrumental methods it is possible to determine trace elements after separation of different fractions from soil and plant samples. Fractions of soils and sediments are obtained by extraction with different reagents, chosen in function of biological, ecological or chemical considerations. In plant samples it is possible to separate free ions and organo-mineral co...
In an earlier study (Alexander et al., 1974) it was shown that the mineral mixture used in association with a synthetic diet was deficient in zinc, copper, iron, and manganese. A new mixture containing appropriately increased amounts of these trace metals has now been evaluated by means of metabolic balance studies carried out on children with phenylketonuria. This new mixture was shown to be s...
Iron is the most abundant trace mineral in the body and is an essential element in most biological systems.1,2 It is likely that iron was essential for developing aerobic life on Earth.3 But iron is toxic to cells in excessive amounts. Acute iron poisoning is common and potentially lethal in dogs, cats, and many other animals. Iron is also a leading cause of unintentional poisoning deaths in ch...
