XRF determination of trace metals in airborne particulates

Abstract

This paper describes a method of measuring trace metals in particulate air pollutants by energy dispersive XRF spectrometry and analysis of measured data. Samples were collected on the filters with three types of low-volume air samplers. Samples collected with a settling type and a cyclone type sampler were not uniform on the filter. Samples collected with a dichotomous sampler were uniform on it. In winter, high concentrations of fine particles containing Pb, Zn, Cu, V and Br had been observed. In spring, high concentrations of coarse particles had been determined because of yellow sand phenomena.
