Abstract:
Jaipur is the capital state of Rajasthan. During the year 2021, District Jaipur of 3 blocks (Chomu, Sanganer, and Shahpura) in 9 villages [Keshav Nagar (V₁), Morija (V₂), Nindola (V₃), Goner (V₄), Shrikishanpura (V₅), Durgapura (V₆), Shivpuri (V₇), Manoharpur (V₈), Nwalpura (V₉)] were selected for estimation of physico-chemical properties of soil and Heavy metals contamination in sewerage channels. A total of 9 samples were collected from 9 villages sewerage channels and soils. This study aimed to analyze the physico-chemical properties of agricultural soil and irrigation water in three blocks of Jaipur, Rajasthan. The findings revealed significant variations in the physico-chemical properties of the agricultural soil and water in Chomu, Sanganer, and Shahpura. Standard methods were employed to assess the physico-chemical characteristics of soil samples contaminated with sewerage effluents in these regions, which exhibited considerable diversity. The pH levels of the soil samples were predominantly slightly acidic and alkaline ranging from 6.22 to 7.31. Electrical conductivity values varied between 0.41 to 0.62 mmhos/cm. The percentages of organic matter and organic carbon in the soil samples ranged from 0.17% to 0.25% and 0.29% to 0.43%, respectively. Additionally, the analysis included heavy metals such as zinc (Zn), manganese (Mn), iron (Fe), and copper (Cu). The soil samples were found to contain elevated levels of heavy metals, surpassing the permissible limits. The discharge of sewerage effluent into the environment, primarily originating from the textile industry, house, etc. constitutes are major source of pollution that can adversely impact the local flora and fauna. Therefore, it is imperative to implement effluent treatment measures before their release into the environment.
