4. Results and Discussion 4.1. Hydrochemistry of Groundwater Table 1 shows the hydrochemical analysis of the GW sample parameters collected from the study area. The depth value of the GW resources in the study area ranged between 66 and 117 (feet) with a mean value of 91.6 (feet). The values of the pH of the GW samples differed between 7.3 and 8.6, with a mean value of 7.96, and was below the suggested limit of the WHO.

3. Results and Discussion The physicochemical properties of the soils, i.e., pH, electrical conductivity (EC), organic matter (OM) content, and percentage moisture content (MC) under four different land-use systems (permafrost, forest, pasture, and agricultural soil) are shown in Table 1. Table 1 shows the greatest pH value was investigated in the pasture soils of Babusar Valley (7.452), and the lowest value was observed in the forest soils of Babusar Valley (7.0).

1. Introduction Mn and its compounds are one of the important occupational hazards. Occupational groups such as welders and ferroalloy makers are susceptible to Mn poisoning when exposed at low concentrations for long periods of time (1), and occupational groups are exposed to Mn mainly through inhalation of Mn-containing fumes (2).
