“…Its unique properties make it indispensable for the development and optimization of various cutting-edge technologies. Rapid advances in technology have led to a growing demand for tungsten; however, its extensive use can lead to an undesirable increase in its release into the environment [2,3].…”

Tungsten is an essential element for many cutting-edge industries. Its use is increasing, so much that it has become a “critical element”. With the increase in the use of tungsten, a possible increase in its presence in environmental matrices including soil is expected. In this research, we assessed the environmental availability and bioaccessibility of W in relation to soil properties. Four representative Mediterranean soils, collected in Italy, were spiked with tungsten and incubated for 12 months. In the spiked soils, the environmental availability of the element was determined by the Wenzel sequential extractions. The bioaccessibility was determined by the UBM (BARGE) method in both the gastric and intestinal phases. The findings indicated that the environmental availability is largely influenced by soil properties such as pH and organic matter, while a lower influence was discovered for bioaccessibility, particularly for the gastric phase. These differences could be ascribed to the characteristics of the extractants utilized in the various tests, in particular the pH values. These results could be a valuable reference to integrate with studies on really and not spiked contaminated soils, for the improvement of risk assessments and the development of strategies for remediating soils polluted with tungsten.

“…Nowadays, tungsten (W) is not only a critical raw material with a wide range of applications, but also an object of intense scrutiny for its impact on the environment, one of the most important elements of which is soil (Bolan et al, 2023). The sources of W in soils, its content, distribution, bioavailability, toxicity, mobility and migration are key research topics, especially for areas with current or past mining and metallurgical activities.…”

A four-step sequential extraction procedure (SEP) was used to assess the distribution of W fractionation in the topsoil (0–20 cm) of the soil above the oxidation zone of the W deposit. Data on the extraction of W and other elements were obtained using LA-ICP-MS and SEM-EDX analyses of the dried, sieved and finely grinded original soil and residual samples after each step of the procedure. When processing LA-ICP-MS data, the SiO2 content of the original soil was used as an internal standard for all samples in the sequential extraction procedure. It was found that of the approximately 90 ppm of total W content in the soil, about 25% is associated with organic matter, 40% with amorphous hydrous Fe oxides (ferrihydrite), 25% with crystalline hydrous Fe oxides (goethite), and about 10% with residual material (scheelite, silicates).
