Determination of trace elements in urban airborne particulates (PM10) using energy dispersive X-ray fluorescence (EDXRF) spectroscopy

Abstract

Assessment of the air quality in Newcastle upon Tyne, UK was performed by determining the trace element content in airborne particulates (PM₁₀). Samples were collected over a 12 month period (March 2011 to April 2012) using two high volume air sampler provided with a PM₁₀ size selective inlet. The concentrations of 6 elements (Cr, Cu, Mn, Ni, Pb and Zn) were determined. The mean concentrations of these elements varied widely across the elements with Zn showing the highest concentration (41.3 ± 42.8 ng/m³; ranging from 9.9 – 209.0 ng/m³) and Cr the least concentration (1.7 ± 0.9 ng/m³; ranging from 0.4 – 3.2 ng/m³). The total elemental content obtained in this work was compared with regulatory limit values for 4 of the elements determined and it was discovered that none exceeded the limit values. ©
