Trace element speciation in toxicology and clinical sciences

Trace Element Speciation and Behavior in the Tidal Delaware River

Measurements of dissolved As, Cr, Cu, and S~ using species-selective techniques were made in the tidal freshwater Delaware River at four sites in July 1991, January 1992, and March 1992. Concentrations of dissolved As, Cr, and Se were generally higher in July than in March or January. Copper concentrations were relatively constant. Both As and Cu increased in concentration in the region of Phil...

Trace-element analysis in clinical chemistry.

Present knowledge of human bodily contents and concentrations in blood, urine, and hair of 11 essential trace elements and 17-22 nonessential inert or toxic trace elements is reviewed and summarized. Analyses of trace elements are applicable as diagnostic aids and indices for therapy in a number of clinical conditions. Techniques are not difficult, and analyses will probably become more or less...

Trace Metals and Phosphorous Speciation

Trace Element Estimation – Methods & Clinical Context

Understanding the effects of trace metals on human health is as complex as it is fascinating. As mentioned earlier, the high concentrations may prove toxic, as also, depletion in the concentration of the essential trace elements may cause various metabolic instabilities due to enzyme dysfunction. In the era of rapid industrialization and technological advances, it is imperative to watch keenly ...

Trace Element Deficiency in Infants and Children — Clinical practice —

Trace element deficiencies commonly encountered in Japanese infants and children are discussed. Premature birth infants have a high likelihood of developing deficiency of trace elements such as iron, zinc, and selenium, during the period of rapid growth from 2 months to 6 months of age. Breast-fed infants, in particular, are prone to develop trace element deficiency, and alopecia and dermatitis...
