“…At present, geophysical techniques widely used in urban underground space exploration include electrical resistivity tomography (ERT), shallow transient electromagnetic method, ground-penetrating radar, cross-well CT (electromagnetic and seismic wave), shallow seismic (p-wave, s-wave, surface wave, and microtremor), acoustic wave, microgravity, and integrated geophysical prospecting methods [2][3][4][5]. Karst [2,3] and fault [6,7] are the most extensive exploration objects in many urban underground space exploration applications.…”

The development and utilization of urban underground space are of great significance to urban sustainable development. Geophysical methods have the characteristics of non-destructive detection, and electrical resistivity tomography has an obvious response to underground resistivity structure and can be used in urban underground space exploration. In this paper, COMSOL Multiphysics is used to realize the finite-element simulation of geoelectric models, and electrical resistivity tomography is used to explore resistivity anomalies of karst and fault models in urban underground environments. The results show that electrical resistivity tomography can identify karst and fault distribution effectively, and COMSOL Multiphysics promises to be a powerful tool for exploring urban underground space.

“…The determination of concentrations of rare earth elements (REEs) continues to be important today in metallurgical, biological, medical, and environmental fields (Fujinawa 1992, Li et al 2012, Miao et al 2008, Li et al 2011. At a time when the greatest advances in analytical methods are available, REEs' researchers and industries are looking for methods that will enable them to obtain reliable results in acceptable time frames and at low cost, which is challenging for some type of samples (Gorbatenko and Revina 2015, Fisher and Kara 2016, Balaram 2019.…”

“…The accumulation, differentiation and exchange of trance elements in soil-plant system, is one of the interface behavior between the inorganic world and biosphere, and has important significance on the ecological and environmental system [3] . Though trace elements have been extensively studied due to their importance in tacking environmental issues [4,5,6,7] , the geochemical characteristics of trace elements from rocks, soils to plants and the relation with each other are seldom taken into consideration. What's more, large numbers of inactive trace elements in primary mineral burst into the soils environment by the mining activity, which may have a significant effect on the ecological and environmental system around.…”

This study aims to obtain an overview of trace elements concentrations in rocks, soils and plants from Puxiong lead-zinc mining area in Yunnan, China, and analyze the connection as well. Concentrations of Ba, Cd, Co, Cu, Mn, Pb, Zn, As, Sb, Hg, Sn, Ni and Sr among soils, rocks and three dominant plants in mining area, transition area and background were measured. Ratio parameter, bioconcentration factors (BF) and Pearson's correlation coefficients were used to analyze the relationship between these elements in different feature. The results indicate that rocks, soils and plants samples are all characterized by high concentrations of Pb, Zn and other associated elements in Puxiong lead-zinc mining area. Geochemistry of trace elements concentrations from rocks to soils, then to plants presents obvious characters of inheritance and variability. Whats more, three dominant plants are same in high concentration of Mn and low concentration of Cd, Hg, Co, but are huge different in bio-concentration factors.
