stable isotope analysis, being used in many research areas, has also been applied in archaeology during the last three decades to address questions regarding the paleoclimatology and ancient diet, mobility and migration. despite the growing number of the application of stable isotope analysis in archaeological studies, there is a very few research in this regard in archaeology of iran. this res...

spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. this review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. the use of an appropriate sample handling technique is a...

the concentration contents of ca, mg, sr and zn in porites corals from pulau langkawi, pulau redang and pulau tioman were presented. the corals were cleaned and the growth rate examined visually. the growth rate of porites in malaysia waters was between 5 to 25 mm yr-1 and each band was selected for determining the metal contents using the atomic absorption spectrophotometer (aas). the mean val...

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...

The clinical interpretation of trace element analysis has lagged behind the technology available to measure the elements in body fluids. Reports can be difficult to interpret and requires knowledge of toxicokinetics, the dynamics of how the trace metals accumulate and pass through the body. Trace element analysis is best used for specific applications, such as establishing levels of exposure, b...
