There is a growing need for chemical analyses to be performed in the field, at the point of
need. Tools and techniques often found in analytical chemistry laboratories are necessary in …

This paper reviews the use of pXRF in elemental assessment of vegetation, with emphasis
on the factors that affect pXRF readings, including water content, protective film effect, critical …

Heavy metal and metalloid contamination of farmland soils are closely related to human
health. Soil contamination caused by small-scale mining activities has been largely …

The lag in quantitative methods and detection techniques for geologic information has
resulted in time-consuming and human-experienced geologic analysis in tunnels …

High-precision map** based on portable X-ray fluorescence (PXRF) data is currently
being studied extensively; however, owing to poor correlation with soil metal concentration …

Atmospheric dust is contaminated by trace metals in many parts of the world due to human
industrial activities. This study evaluates tree stumps as passive samplers of dust deposition …

Soil is an important source of potentially toxic metal intake for humans through the food
chain. Accurate determination of elemental concentrations in soil is of great significance to …

In the study of the inversion of soil multi-species heavy metal element concentrations using
hyperspectral techniques, the selection of feature bands is very important. However …

This research explored the feasibility of using portable X-ray fluorescence (pXRF)
spectrometry to quantify Fe, Cu, Zn, and As concentrations in dried and ground organic …

In order to develop methods to determine the chemical composition of Waste Printed Circuit
Boards (WPCB), this study focused on the analysis of 10 metals (Cu, Fe, Sn, Zn, Pb, Ni, Sb …
