Determination of multi-element profiles of soil using energy dispersive X-ray fluorescence (EDXRF).
The source profile for soil in Hong Kong is important both for determination of the main air pollutant source in Hong Kong and for assessment of the impact of Asian dust storms on Hong Kong. Soil associated with different rock types have been sampled, and the concentrations of 19 chemical elements, Na, Al, Si, Ti, V, Cr, Mn, Fe, Co, K, Ca, Ni, Cu, Zn, Pb, Rb, Sr, Y and Zr, have been determined ...
متن کاملStudy of Heavy Metals and Other Elements in Macrophyte Algae Using Energy-dispersive X-ray Fluorescence
Fucus vesiculosus L. seaweeds from three estuarine stations were analysed by X-ray fluorescence, providing results for the concentration of total In order to study the differential accumulation of heavy metals by different parts of Fucus, four different structures of the algae, base, stipe reproductive organs and growing tips, were analysed. Some elements (e.g. Cu and Fe) are preferentially acc...
متن کاملStudy of air pollutants in Hong Kong using energy dispersive X-ray fluorescence.
Airborne particulate samples were collected from various reference sites in Hong Kong and the energy dispersive X-ray fluorescence (EDXRF) intensities for 19 chemical elements were recorded. Principal component analysis (PCA) was employed so that the variances of these 19 original variables were captured by a few new indices called principal components or PCs. Data points for similar sources we...
متن کاملEnergy dispersive x-ray analysis in the study of pneumoconiosis.
Identification of inorganic substances in the lung is an important step towards the establishment of a cause and effect relationship in the study of pneumoconiosis. The conventional methods for this identification usually require an ashing which makes it difficult to study the localisation of these substances in relation to pathology. A method is described to identify foreign substances in the ...
متن کاملDirect rapid analysis of trace bioavailable soil macronutrients by chemometrics-assisted energy dispersive X-ray fluorescence and scattering spectrometry.
Precision agriculture depends on the knowledge and management of soil quality (SQ), which calls for affordable, simple and rapid but accurate analysis of bioavailable soil nutrients. Conventional SQ analysis methods are tedious and expensive. We demonstrate the utility of a new chemometrics-assisted energy dispersive X-ray fluorescence and scattering (EDXRFS) spectroscopy method we have develop...
