The concentrations of five essential elements and six potentially toxic elements were determined in seven organs collected at autopsy from 30 human subjects. Elemental analyses were carried out by graphite furnace atomic absorption spectroscopy, and inductively coupled plasma emission spectroscopy, and inductively coupled plasma mass spectroscopy, and concentrations in fresh and formalin-fixed ...

the larsemann hills range is an ice-free oasis on the ingrid christensen coast of princess elizabeth land, east antarctica, which includes bharti island, fisher island, mcleod island, broknes peninsula, stornes peninsula, and several other islands, promontories, and nunataks. the larsemann hills is an ice-free area of approximately 50 km2, located halfway between the vestfold hills and the amer...

A methodology for the production of PbSe targets 79Se neutron capture cross section studies is presented. material was synthesized by direct reaction its constituents at high temperature, and characterized X-ray diffraction. Thin targets, produced experiments with surrogate method, were obtained applying a physical vapor deposition technique, their morphology composition analyzed fluorescence, ...

glazers are exposed to a variety of heavy metals in the ceramic industry, causing adverse effect on the body systems. cadmium is one of the major raw materials for production of colored glazes. to evaluate occupational exposure to cadmium, spot urine samples were collected from 49 tile and pottery glazers n yazd city in 2010 at the beginning and end of the work shift (98 samples). totally, 55 o...

Polypropylene (PP) powders are coated with silica nanoparticles in a fluidized bed to improve the flow behavior of and processability powder fusion. The produced situ via dusty plasma-enhanced chemical vapor deposition (PECVD) an atmospheric-pressure Ar/O2 plasma jet fixed at distributor plate bed. Hexamethyldisiloxane is used as precursor nanoparticles. influence oxygen concentration gas numbe...

Tepe Sagzabad, a site situated on the Qazvin Plain of north-central Iran, was excavated from 1970 to 1998 by the Institute ofArchaeology of Tehran University. Recent excavations by H. Tala’i (1997-1999) yielded some metal artifacts dating to theEarly Iron Age. Ten of these copper-based samples were investigated using inductively coupled plasma optical emissionspectroscopy (ICP-OES), scanning el...

The Nutrition Labeling Education Act of 1990 (NLEA) mandates significant reform of food labels and requires extensive chemical testing and analytical method development to implement. Many minerals and nutrient metals are targeted for labeling. Part of the analytical challenge to be met results from the large numbers of samples to be tested and widely divergent levels of the elements of interest...
