“…About this commercial gel, its most components are aqua, carbomer, Phenoxyethanol (and) decylene glycol (and) caprly glycol, triethanolamine, and glycerine. Due to its features, it does not leave any stain, and it removes effortlessly [6].…”

“…As a result, geophysics has been extensively used in geology, mining, environmental studies, hydrogeology, agriculture, forensics, civil engineering, e.g. [1][2][3][4][5][6], and where their use in archaeology has not been different due to their proved capabilities. In fact, applied geophysics in archaeology is carried out in the early stages of a subsurface investigation, before any other invasive actions that could damage potential hidden structures, as a useful tool to guide and support all the whole process [7,8].…”

“…Several correlations between high loads of specific heavy metals content (Cd, Pb, Al, Fe, Mn, Zn, Mo, V, Cr, Ni and Co) and electric response have been proposed (Abu-Zeid et al 2004). For instance, the physicochemical characterization of phosphogypsum pond using geochemical and geophysical techniques based on ERT measurements allowed the prediction of the heavy metals spatial distribution through statistical models showing that the most concentrate metal is chromium with a maximum of ≈ 900 mg kg −1 and Cd is the least concentrated of maximum ≈ 23 mg kg −1 (Vásconez-Maza et al 2021). Previous studies reported a decreasing tendency of resistivity with the increase of heavy metal ion concentrations (Zn 2+ , Cd 2+ and Pb 2+ ) in contaminated soils (Chu et al 2017).…”

“…The underground components respond differently to electrical currents generating an electrical contrast signal. The presence of some metals decreases the electrical resistivity values generating a significant electrical contrast with the background; that is why, heavy metals resistivity is a proxy for predicting soil contamination distribution (Vásconez-Maza et al 2020). In the context of soil mapping, electrical resistivity exhibits a large range of values; for instance, from 1 Ω m for saline soils to 105 Ω m for dry soils overlaying crystalline rocks (Samouëlian et al 2005).…”

Cadmium is a toxic non-essential metal for almost all living systems. It is one of the biggest challenges for farmlands and the food chain because of its toxic effect on human health. This research aims to determine the Cd content in soils, litter and cacao beans, following the Cd fluxes within each cacao system using the two-dimensional electrical resistivity tomography technique. The study was carried out in four farms located in the Magdalena basin in Antioquia, Colombia. The farms showed a heterogeneity in relation to cacao cultivars, altitude, topography and geology. The soil cation electrical capacity, pH and soil organic matter levels, as well as the Al, Al 3+ H + , Ca, K, Mg and P contents were measured at different depths. Moreover, the Cd content was correlated to the resistivity values of samples taken in situ using ERT. Soil Al 3+ H + and the altitude of the farms fitted as the best predictors of the beans' Cd content. Furthermore, the Cd content in soils from the assessed farms ranged between 1.22 and 2.03 mg kg −1 . The Cd content in cocoa beans ranged from 0.07 to 1.44 mg kg −1 , with a value of 0.40 mg kg −1 on average. The resistivity values obtained in field showed a high correlation with the soil Cd content determined (R 2 = 0.82). The predictive tomography plots highlighted topsoil Cd dynamics between litter, amendments and fertilizers. Therefore, these results underlie the utility of the combined geophysical techniques and soil chemical properties including the analysis of fertilizer amendments to improve the understanding of Cd dynamic.

“…In addition, PG can also produce raw materials such as sulfuric acid co-production cement, construction gypsum powder, cement retarder, and other building materials indirectly (Chen et al, 2018). At present, many scholars have done a lot of research on the environmental impacts and treatment technologies of PG, such as the radiological and elemental hazards (Attallah et al, 2019;Qamouche et al, 2020), the behaviour of heavy metals (Guerrero et al, 2021;Vasconez-Maza et al, 2021), optimum design of PG storage yard (Millan-Becerro et al, 2020), and the pretreatment to remove impurities (Zhang and Zhang, 2018). Most studies, however, are expert-dependent.…”

The demand together with the urgency of phosphogypsum (PG) treatment, will pose big challenges for many countries. This research aims to explore the research progress of PG, including basic status, cooperation situation, research elds and development trends, based on Web of Science database through bibliometric analysis of publications (articles and patents) from 1990 to 2020. The results show that the academic research of PG originated earlier, but the number of patents grew faster. China has an absolute advantage in the numbers and plays a signi cant role in international cooperation. The knowledge structure of PG is mainly concentrated in the elds of natural radioactivity, cement paste back lling, soil, crystal morphology, and synthetic gas. Academic hotspots focus on the microstructure of chemical processes and various environmental impacts, and the patents hot technologies is the production of refractory materials, ceramics, surface materials, cement mortar and composite materials. The academic frontiers of PG will be the methods of recovering rare earth elements from PG, the conditions of ion solidi cation/stabilization in PG, the impact of reaction conditions on product quality, and the reaction mechanism at the micro-level. The frontiers of patents will focus on the improvement of manufacturing equipment, new wall materials and chemical modi ed polymer materials. In terms of the number of articles and patents in the future, architectural research has the maximum space for improvement. This paper conducts an in-depth analysis of PG and provides information on the technological development prospects and opportunities, which is helpful for researchers engaged in PG management.
