JJZ132、JJZ161土壤中苯并(k)荧蒽检测数据

苯并(k)荧蒽，是一种有机化合物，为黄色结晶性粉末，溶于乙醇、苯和乙酸，主要用作环境保护研究用标准样品。是判定土壤污染程度的重要指标，分别分析不同层，可以全面了解土壤的质量、污染状况和环境特征，为土壤管理、项目建设和环境保护提供科学依据，有助于实现可持续农业和生态环境的保护与改善，为土壤样品分析评价提供事实依据，是判断土壤环境污染程度的重要指标。为历史情况相似地块提供数据参考。为监管部门提供依据。1、数据来源：按照土壤和沉积物 半挥发性有机物的测定 气相色谱-质谱法 HJ 834-2017对土壤进行土样采集检测。2、算法规则：按照如下公式进行计算：样品浓度=（样品查曲线值W-空白查曲线值）*定容体积V*稀释倍数D/取样量m/(干物质含量w/100))，公式中样品浓度单位为mg/kg；样品查曲线值及空白查曲线值单位为μg/mL；定容体积单位为mL；取样量单位为g，干物质含量单位为%。3、数据判定：根据《建设用地土壤污染风险管控标准（试行）》（GB36600-2018）第一类用地风险筛选值进行判定，若苯并(k)荧蒽浓度数据≤55mg/kg，则判定土壤中该指标浓度达标，反之则超标。4、数据应用：通过分析土壤中苯并(k)荧蒽的浓度，我们可以判断该土壤中苯并(k)荧蒽的达标情况，避免因该指标浓度含量高引起土壤的污染问题，为监管提供依据。Benzo(k)fluoranthene is an organic compound that exists as yellow crystalline powder, soluble in ethanol, benzene and acetic acid. It is primarily utilized as standard reference materials for environmental protection research, and serves as a critical indicator for assessing soil pollution levels. Analyzing different soil layers enables comprehensive understanding of soil quality, pollution status and environmental characteristics, providing scientific support for soil management, project construction and environmental protection. It facilitates the achievement of sustainable agriculture and the protection and improvement of the ecological environment, and offers factual evidence for soil sample analysis and evaluation, acting as a key metric to judge the degree of soil environmental pollution. Additionally, it provides data reference for plots with similar historical conditions, and supplies basis for regulatory authorities. 1. Data Source: Soil samples were collected and tested in accordance with the Standard for the Determination of Semivolatile Organic Compounds in Soils and Sediments by Gas Chromatography-Mass Spectrometry HJ 834-2017. 2. Algorithm Rules: Calculations are conducted using the following formula: Sample concentration = (W_sample - W_blank) × V × D / m / (w/100) Where: the unit of sample concentration is mg/kg; the units of W_sample (sample curve-derived value) and W_blank (blank curve-derived value) are μg/mL; the unit of constant volume V is mL; the unit of sampling mass m is g; the unit of dry matter content w is %. 3. Data Judgment: The determination is made in accordance with the Risk Screening Values for Category 1 Land Use in the Standard for Risk Management and Control of Soil Pollution in Construction Land (for Trial Implementation) (GB36600-2018). If the concentration of Benzo(k)fluoranthene is ≤55 mg/kg, the concentration of this indicator in the soil is considered compliant; otherwise, it exceeds the standard. 4. Data Application: By analyzing the concentration of Benzo(k)fluoranthene in soil, the compliance status of this indicator in the soil can be determined, thereby preventing soil pollution caused by excessive concentration of this indicator, and providing a basis for supervision work.
