plautonili-1 determination in biological samples

most of the plutonium isotopes are alpha-emitters, a fact which is of decisive importance from a biological point of view. we shall consider their potential danger to life in general, and to human life in particular. in this respect measurement of plutonium concentration in air and soil and vegetable is the object of systematic tests in numerous countries. this plutonium occurs in the fallout f...

Spectrophotometric Determination of Selenium in Environmental, Biological and Pharmaceutical Samples

Analytical Determination of Stannanes in Different Biological Samples

Three species of stannanes were determined in different biological samples obtained from the sea water of the Arabian Gulf. Following digestion with acetonitrile, and extraction with n-hexane, the analytes were derivatized and subsequently analyzed in gas chromatography mass spectrometric system. Five-point calibrations using the concentration range of 0.05-10 μg/g were linear with coefficients...

The Determination of Iodine Species in Environmental and Biological Samples

Iodine is found in organic forms in plants and animals and in inorganic forms in natural water samples. Methods of identification and quantitative determination for iodine species are decided by the types of compound and the matrices in which they occur. Iodine is an essential element and specific radioimmunoassay methods have been devised for physiologically important compounds (thyroxine and ...
