摘要

土壤在许多刑事审判中是一种至关重要的资源,近年来也得到了一种新的研究方法,许多研究小组的研究目标是改进土壤剖面的区分。该调查于2022-2023年进行,目的是评估北方邦苏尔坦普尔市几个地区的土壤特征。本研究的主要目的是使用物理、化学、显微镜和仪器检查技术对样品进行定量分析。土壤样品从0-15 cm的深度采集,经过分析,发现土壤的颜色根据其组成而变化。通过不同的物理和化学测试,研究了土壤的质地、粘性、可塑性、密度、pH值和可溶性硫酸盐百分比等特征。土壤质地按砂质粘土壤土分类,粘性和可塑性分别为低、中、高。土壤密度范围为1.794 ~ 2.479 g/cm3。土壤样品的pH值总体呈酸性,在6.27 ~ 7.77之间。土壤中可溶性硫酸盐的含量在0.11184 ~ 0.0864之间。采用立体显微镜对土壤样品的颗粒状和棱柱状结构进行了观察。采用原子吸收光谱法(AAS)对土壤样品进行定量分析,测定土壤中微量元素的含量。研究结果表明,每个土壤样品都是不同的,土壤剖面的参数有助于这些土壤样品的区分。研究结果可为土壤的制备提供参考,进一步协助法医开展土壤取证工作。

Soil Analysis from Crime-Prone Areas of Sultanpur City for Forensic Aspect: A Research
The soil is a crucial resource in many criminal trials and the same has received a recent research approach inrecent years, with numerous groups researching with objectives that allow for improved differentiation of soilprofiles. This investigation was conducted in 2022-2023 with the objective of assessment of soil characterizationfrom several areas in Sultanpur City, Uttar Pradesh. The primary goal of this study was to conduct a quantitativeanalysis of the samples using physical, chemical, microscopic and instrumental examination techniques. The soilsamples were collected from a depth of 0-15 cm and after analysing the samples, it was found that the colour of thesoil varies according to its composition. Soil features like texture, stickiness, plasticity, density, pH, and percentageof soluble sulphate were examined using different physical and chemical tests. Soil texture was classified underthe sandy clay loam category and stickiness and plasticity were measured to be less, medium or more. The soildensity ranged from 1.794 g/cm3 to 2.479 g/cm3. The pH of the soil samples was overall acidic, ranging from6.27 - 7.77. The percentage of soluble sulphate in soil varied from 0.11184 - 0.0864.A stereo microscope was used toobserve the granular and prismatic structures of soil samples. Atomic Absorption Spectrometry (AAS) was usedfor quantitative analysis of soil samples to measure the amount of trace elements present in the soil. The studyresults showed that each soil sample varied from another and the parameters used for soil profiling helped in thedifferentiation of these soil samples. The results from this study can be helpful in preparing soil which can furtherassist the forensic scientists in their investigations related to soil as evidence.
