Determination of multi-element profiles of street dust using energy dispersive X-ray fluorescence (EDXRF).
Street dust samples have been collected in different areas in Hong Kong associated with various levels of traffic and pedestrian flow, and the concentrations of 23 chemical elements have been determined using energy dispersive X-ray fluorescence (EDXRF). The 23 studied elements were Na, Al, Si, Cl, Ti, Ba, V, Cr, Mn, Fe, Co, K, Ca, Ni, Cu, Zn, As, Pb, Rb, Sr, Y, Zr and Sn. A profile for average...
متن کاملDetermination 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 کاملDendrochemical patterns of calcium, zinc, and potassium related to internal factors detected by energy dispersive X-ray fluorescence (EDXRF).
Energy dispersive X-ray fluorescence (EDXRF) provides highly sensitive and precise spatial resolution of cation content in individual annual growth rings in trees. The sensitivity and precision have prompted successful applications to forensic dendrochemistry and the timing of environmental releases of contaminants. These applications have highlighted the need to distinguish dendrochemical effe...
متن کاملSimultaneous determination of trace elements in serum by energy-dispersive x-ray fluorescence spectrometry.
Energy-dispersive x-ray fluorescence is applied in the analysis of human serum to determine the concentrations of several elements simultaneously with minimal manipulation of the sample. The analytical procedure has been developed with standard sera, and standardization, detection limits, and reproducibility have been established. A 50-microL sample of diluted serum, to which an internal standa...
متن کاملDetermination of High Zn and Pb Concentrations in Polluted Soils Using Energy-Dispersive X-ray Fluorescence Spectrometry
A method of determination of high Zn and Pb concentrations by means of EDXRF (energy-dispersive X-ray fluorescence spectrometry) is presented. Zn and Pb concentration in soil samples from contaminated areas ranged within a limit of Zn: 800–2000ppm and Pb: 200–600ppm. Soil analysis was conducted directly after the samples had been dried and powdered, as well as in situ in polluted areas. Due to ...
