“…e use of Pb insecticides also significantly increased Pb content in orchard growing areas. It was very common for local agricultural planting to use plastic film, and the residual plastic film in the soil also led to the increase of Cd content in the soil [14]. In the research area, animal husbandry was developed, and livestock manure was considered to be a good supply source of soil Zn.…”

In order to investigate the effects of fertilization on soil chemical characteristics and ecological security, the chemical characteristics and ecological security risk analysis of heavy metal elements in a certain soil caused by fertilization were proposed. The contents of Ni, V, Cr, As, Cd, Pb, Zn, and Hg in 1,065 surface soil samples collected in a district of a city in the southwest agricultural area were tested and analyzed. Multivariate statistical analysis and spatial analysis were used to clarify the geochemical distribution characteristics of these heavy metals, and the possible main sources were also discussed. The results showed that the eight heavy metals could be divided into three categories. The first category included Ni, V, Cr, and As, whose content was lower than the background value in Beijing. And the distribution was mainly affected by natural factors such as parent materials of soil formation. The second category included Cd, Pb, and Zn, whose average content was higher than the background value. And the content was the highest in residential areas. In addition to the parent material inherited from the soil, the distribution characteristics of these elements were greatly affected by human activities. And Cd was significantly more affected by human activities than Pb and Zn. The third category included Hg, and it was inferred that atmospheric deposition was the main factor affecting the distribution of Hg. It was concluded that the Hakanson method was used to evaluate the ecological risk of heavy metals in soil, and the results showed that the potential ecological risk index was low in the area.

“…The distinctly different Na/K ratios in the three geothermal systems can be attributed to either the differences in contact rock composition or a variation in the ratio of liquid and vapor phase sourcing. The Na/K ratios in the Ladakh volcanic range from 1.4 to 20 [47,48], among which the highest Na/K ratio (20) is recorded from the Nidar ophiolite complex associated with Indus Suture Zone, relatively close to Puga and Chumathang geothermal sites, whereas volcanic rocks from the Shyok suture zone, relatively close to Panamik hotspring waters show a Na/K around 3.7. Therefore, the contact rock composition seems an unlikely reason for distinctly different Na/K in the three geothermal systems.…”

Boron (B) and Tungsten (W) are often found enriched in high-temperature geothermal waters associated with the development of subduction-related mafic to felsic arc magma. However, knowledge about the sourcing and transportation of these elements from such hydrothermal systems is sparse and ambiguous. Being the only active continental collision site in the world, the Trans-Himalaya offers a unique chance to study how continental collision sources the high boron and tungsten concentrations in geothermal fluids. This study investigated the distribution of trace elements, major cations, and anions in three physicochemically distinct hotspring sites in the Ladakh region. The results were integrated with the existing geochemical and isotopic data to address the research problem more effectively. This study exhibits that the extreme concentrations of boron, sodium, chlorine, potassium, and tungsten in the hotspring waters were primarily governed by magmatic fluid inputs. In addition, this study recorded the highest-ever chlorine and boron concentrations for the Trans-Himalayan hotspring waters. The highest-ever boron and chlorine concentrations in the hotspring waters probably represented an increase in magmatic activity in the deeper source zone.
