“…The values are within the range, and it is possible that the Na + also might have a marine origin. The concentration of HCO 3 − (8.09 μeq/l) in the Shaune Garang catchment is lower than the reported values of other Himalayan locations and may only be influenced by the local origin of soil and limestone 71 , 72 . Apart from these parameters, Mg 2+ (13.98 μeq/l) is observed to be high compared to other Himalayan locations, but K + (6.56 μeq/l) and Ca 2+ (37.13 μeq/l) are almost similar.…”

The present research has been performed to analyze the chemical behavior of rainwater of the Shaune Garang catchment (32.19° N, 78.20° E) in the Baspa basin, located at a high elevation (4221 m above mean sea level) in the Himachal Himalaya, India. During the study period, sixteen rainwater samples were collected from the Shaune Garang catchment at five different sites. The volume-weighted mean (VWM) pH value of rainwater ranged between 4.59 and 6.73, with an average value of 5.47 ± 0.69, indicating the alkaline nature of rainfall. The total ionic strength in the rainwater ranged from 113.4 to 263.3 µeq/l with an average value of 169.1 ± 40.4 µeq/l. The major dominant cations were Ca2+ (43.10%) and Na+ (31.97%) and anions were Cl− (37.68%), SO42− (28.71%) and NO3− (23.85%) in rainwater. The ionic ratios were calculated among all the ions. The fraction of (NO3− +Cl−) with SO42− was measured as 2.3, which specifies sour faces of rainwater due to HNO3, H2SO4, and HCl. A multivariate statistical assessment of rainwater chemistry through Principal Component Analysis (PCA) shows the significance of four factors controlling 78.37% of the total variance, including four-component (PC1 explained 27.89%, PC2 explained 24.98%, PC3 explained 14.64%, PC4 explained 10.85%). However, the individual contribution of Factor 1(PC1) explains 27.89% of the total variance (78.37%) and displays a strong optimistic loading for Ca2+ and Cl−. Further, high loading of Ca2+ and NO3− and moderate loading of SO42− signify the contribution of burning fossil fuel and soil dust. Anthropogenic and natural pollutants influence the composition of rainwater in the pristine Himalayas due to local and long-distance transportation. The study area receives precipitation from the West and North-West, transporting dust and fossil fuel emissions from the Thar Desert and Northwestern countries.

“…As found, soils of the European Arctic were characterized by very high concentrations of Ni, Cu, and Co, and concentrations of these elements were signi cantly lower in the organic horizon than in the parental matter. As was also concluded by Reimann et al (1998;2001), in some parts of the European Arctic, high concentrations of Ni, Cu and Co were attributed to natural processes rather than to industrial pollution. Autor also made one important conclusion, stating that in the area of the European Arctic, the classic correlation analysis was a questionable tool for analyses of correlations between concentrations of elements and suggested the use of grouping analysis.…”

“…The measurements used in this study were performed in Norway in the vicinity of the city of Mo, which is located just south of the Arctic Circle. Concentrations of selected elements in soils of the region of the European Arctic were previously studied by Reimann et al (1998;2001). Samples used in this study were taken from the moss and O, B, and C soil horizons.…”

This study aimed to investigate the value of magnetic susceptibility within a fjord located on the border of the Arctic Circle. A suitable research area was established near the town of Mo, where magnetometric and chemical measurements were made in four measurement areas. These areas were located at varying distances from Ranfjorden. In addition, a large industrial area, Mo Industrial Park, was located at the research site, and the measurement areas were located so that the distance to this potential source of pollution was also different. As a consequence, the measurement areas were characterized by both varied anthropogenic pressure and natural conditions. During the study, the values of the soil magnetic susceptibility and concentrations of 18 elements in the soil were measured, which were later used to calculate selected measures of spatial continuity as well as classical statistics and factor analysis. The values of soil magnetic susceptibility measured in individual areas decreased with distance from the potential pollution source, Mo Industrial Park, which may suggest that the soils located away from the potential emission source were characterized by a lower concentration of technogenic magnetic particles (TMP). A similar situation was observed in the case of selected concentrations of elements in the soil and in the case of selected parameters of spatial correlations of soil magnetic susceptibility, which were characterized by a similar tendency of changes as in the case of magnetic susceptibility.
