“…The salt content will have higher influence on the measured resistivity in marine clays than the grain size distribution and density. The same observations are reported by [32]. From the curves presented, the increase in water content slightly decreased the electrical resistivity and the pH of the soil samples.…”

In recent years, the use of electrical methods has been improved considerably in several areas such as environment, agronomy, geophysics and geotechnics. Electrical resistivity may be used as a parameter in soil characterization; it may have many advantages for the determination of geotechnical factors influencing the behavior of soil. In this research, laboratory tests were carried out on natural sodic soil from the region of Ain Nouissy (Mostaganem) to investigate the geotechnical and chemical behavior of a natural soil using electrical resistivity measurements under various conditions. This study aims therefore to identify relationships between electrical resistivity of the soil and some physical and chemical parameters such as water content, porosity, salt concentration and pH. Moreover, electrical resistivity has been measured with the addition of salts into the natural soil. The results show that electrical resistivity reduced drastically with the addition of salt. The obtained results will be used to evaluate properties needed for soil characterization, as well as to track soil behavior with respect to salt concentration for use in soil remediation.

Radiocesium released by the severe nuclear accident and nuclear weapon test is a hazardous material. Illitic clays play a key role in the spatial distribution of radiocesium in groundwater environments due to selective uptake sites at the illite mineral, such as frayed edge sites. However, the cesium uptake capabilities of illitic clays are diverse, which could be associated with the illite crystallinity. This study was performed to determine the cesium uptake of illitic clays and evaluate the crystallinity effects on cesium uptake using statistical approaches. A total of 10 illitic clays showed various crystallinity, which was parameterized by the full width at half maximum (FWHM) at 10 Å XRD peak ranging from 0.15 to 0.64. The uptake behavior of illitic clays was well fitted with the Freundlich model (i.e., r2 > 0.946). The uptake efficiency of illitic clays increased with the decrease in dissolved cesium concentrations. The cesium uptake was significantly correlated with the FWHM and cation exchange capacity, suggesting that the uptake becomes higher with decreasing crystallinity through expansion of the edge site and/or formation of ion-exchangeable sites.

BackgroundBaijiu is a very complex system and its flavor substances are endogenous, influenced by raw materials, starter, production process, production region and other factors. The production region directly affects the composition of flavor substances and quality of baijiu. However, identification of baijiu region is challenging because the corresponding relationship between the production region and baijiu quality is not clear, and the identification of regionalmarkers is indeterminate. In this study, the differences in volatile components of sauce‐aroma style baijiu from four representative regions were investigated.ResultsA total of 94 volatile compounds were identified in samples tested. Additionally, it was verified that 35 potential flavor substances had important contributions to the aroma of sauce‐aroma style baijiu. Meanwhile, nine potential regionalmarkers were screened through multivariate analysis. Further, based on distribution of volatile compounds and the results of sensory evaluation combined with multivariate analysis, a molecular matrix and correlation network were established according to the results of addition experiments, which showed that six substances had a significant impact on the flavor of the tested samples.ConclusionSix key flavor substances (ethyl octanoate, ethyl 2‐methylpropanoate, propyl acetate, ethyl heptanoate, 2‐nonanone and butyl hexanoate) were considered as important regionalmarkers to effectively identify the production region of sauce‐aroma style baijiu. © 2023 Society of Chemical Industry.
