Geochemical Monitoring of Dust Fallout from the Highway Using a Portable X-Ray Fluorescence Spectrometer

Аннотация

Dust fallout is one of the major sources of soil pollution in urban landscapes. The possibility of using portable X-ray fluorescence spectrometers for monitoring of dust loads from the highway is shown here. The composition of dust fallout from the Moscow Ring Road in 2011–2015 was estimated using a portable Thermo Niton XL3t analyzer. Based on the available data, the load dynamics of dust and toxic metals (Zn, Pb, Cu, Ni, Cr, V, and Mn) are traced over the last 15 years.
