Simple method for emission spectrographic determination of trace elements in airborne particulates

Nuclear Activation Techniques for the Determination of Trace Elements in Atmospheric Aerosols, Particulates and Sludge Samples

Activation analysis is one of the major techniques for the determination of many minor and trace elements in a large variety of solid environmental and pollution samples, such as atmospheric aerosols, particulate emissions, fly ash, coal, incineration ash and sewage sludge, etc. Neutron activation analysis of total, inhalable or respirable airborne particulate matter collected on a filter or in...

A proton induced X-ray emission (PIXE) analysis of concentration of trace elements in varicose veins

Background: Proton induced X-ray emission (PIXE) has been applied as reliable and improved techniques in this study to compare concentration of various trace elements in normal and abnormal varicose veins. Materials and Methods: Five samples from normal veins and 13 samples from varicose veins bombarded by 2.0 MeV energy proton beams produced by a Van de Graff accelerator in vacuum. T...

Determination of selected trace elements in airborne aerosol particles using different sample preparation.

Determination of trace element concentrations in atmospheric aerosols is important because of their toxic effects on human health. Additionally, they are now widely used in source apportionment studies. There is a number of methods for sample preparation of ambient particulate matter. One of the most widely used is microwave-assisted digestion of filter-based samples. Since the water-soluble fr...

Determination and Application of Trace Elements

It is a well known fact that minera l plays an important role in the nutrition of animal and plant. The t race elements, which are a part of the mineral and exi st in a very small amount in the living bodies, include not only essential elements but also harmfu l and useless elements. In the researches up until now, physiological significance or essentiality for living body of such elements as c...
