Proximal sensors have been increasingly used for a variety of purposes worldwide, with
great interest on portable X-ray fluorescence (pXRF) spectrometry applications in Soil …

Filamentous fungi native to heavy metals (HMs) contaminated sites have great potential for
bioremediation, yet are still often underexploited. This research aimed to assess the HMs …

Copper (Cu) at ancient metallurgy sites represents the earliest instance of anthropogenically
generated metal pollution. Such sites are spread across a wide range of environments from …

Soil base saturation percentage (BSP) plays an important role in the assessment of soil
taxonomic classification and soil fertility. Conventionally, soil BSP measurement methods …

Elemental concentrations in vegetation are of critical importance, whether establishing plant
essential element concentrations (toxicity vs. deficiency) or investigating deleterious …

We examined the impact of three different sample preparation methods on bulk soil
geochemistry data obtained from a hand‐held, portable X‐ray fluorescence (pXRF) …

Landfill agricultural soils are common worldwide and pose risks to human health via heavy
metals common in such systems. Similarly, anthropogenically deposited organic matrices …

In this study, elemental data from portable X-ray fluorescence (PXRF) spectrometry was
used to test the efficiency of four machine learning techniques (random forest; linear and …

Portable X-ray fluorescence (pXRF) spectrometers can be used to determine the elemental
composition easily, rapidly, and without using chemical reagents, which is very important for …

Management of micronutrient levels in soils must be done carefully to avoid their deficiency
or toxicity to plants. The laboratory determination of micronutrient contents is time …
