土壤污染物中石油烃物质含量检测数据

通过检测数据分析研判，我们可以判断土壤污染物中石油烃物质是否超标，避免因石油烃物质持续污染而产生的污染问题，有以下几点作用。一、进行土壤污染治理可以减少农作物中的该有害物质含量，确保食品的质量和安全；二、根据检测结果可有针对的改善士壤质量，提高土壤的生产力，可以为农业发展提供可持续的基础，同时也有利于保护和改善环境。另外可结合地理信息系统（GIS）技术，将各地点的土壤地理数据和污染物含量信息进行深度整合和分析，绘制位置-污染物含量地图，以直观的可视化形式呈现给用户，增强地理位置与污染物含量关系的理解，构建起一个包含污染源、污染物种类、污染程度、污染扩散路径等多维度信息的地理图谱。这一图谱不仅能够提供实时的监测数据，还能够通过数据之间的关联性，揭示潜在的污染风险和趋势。数据采集:对各地区不同地点进行土壤采集，不同地点采集的土壤按样品编号进行划分，对采集的土壤污染物中石油烃物质进行含量检测。数据判定:按X= C2* V0*D/ Vw 公式中X为土壤污染物中石油烃物质含量，式中C2为萃取液中浓度；V0为萃取液体积，D为稀释倍数，Vw为取样量。石油烃物质含量标准要求为50mg/kg，若土壤污染物中石油烃物质含量不大于50mg/kg，则该土壤的检测结果为合格，否则检测结果为不合格。另外当月石油烃物质含量与上月历史含量相比，污染程度可评为加重、减轻和持平。

Through data analysis and evaluation of detection results, we can determine whether petroleum hydrocarbons in soil pollutants exceed regulatory limits, thereby preventing pollution issues caused by sustained petroleum hydrocarbon contamination. This dataset provides the following core functions:
1. Implementing soil pollution remediation can reduce the concentration of petroleum hydrocarbons (the targeted harmful substance) in crops, ensuring the quality and safety of agricultural products;
2. Targeted improvement of soil quality can be conducted based on the test results, enhancing soil productivity, providing a sustainable foundation for agricultural development, and simultaneously facilitating environmental protection and improvement.

Additionally, by integrating Geographic Information System (GIS) technology, we can deeply integrate and analyze soil geographic data and pollutant concentration information from different locations, generate location-pollutant concentration maps, present these maps to users in an intuitive visual format, improve public understanding of the correlation between geographic locations and pollutant concentrations, and construct a geographic knowledge graph that covers multi-dimensional information including pollution sources, pollutant types, pollution levels, and pollution diffusion paths. This knowledge graph can not only provide real-time monitoring data, but also uncover potential pollution risks and trends through the interrelationships between different data points.

#### Data Collection
Soil samples are collected from various locations across different regions, categorized by their sample numbers, and the content of petroleum hydrocarbons in the soil pollutants is detected.

#### Data Judgment
The petroleum hydrocarbon content in soil pollutants is calculated using the formula: $X = C_2 imes V_0 imes D / V_w$, where $X$ represents the petroleum hydrocarbon content in soil pollutants, $C_2$ is the concentration of the extract, $V_0$ is the volume of the extract, $D$ is the dilution factor, and $V_w$ is the sampling volume. The regulatory standard limit for petroleum hydrocarbon content is 50 mg/kg. If the petroleum hydrocarbon content in soil pollutants is no greater than 50 mg/kg, the test result of the soil sample is qualified; otherwise, the result is unqualified. In addition, when comparing the petroleum hydrocarbon content of the current month with the historical data from the previous month, the pollution level can be classified into three categories: aggravated, alleviated, and unchanged.
