椒江区JJZ132、JJZ161土壤中苯并(a)蒽检测数据

苯并(a)蒽溶于乙醇、乙醚、丙酮和苯，本品在工业上无生产和使用价值，一般只作为生产过程中形成的副产物随废气排放，经过环境系统循环，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(a)蒽浓度数据≤5.5mg/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(a)蒽的浓度，我们可以判断该土壤中苯并(a)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(a)anthracene is soluble in ethanol, diethyl ether, acetone and benzene. This compound has no production or application value in industry, and is generally only discharged as a byproduct formed during production along with waste gas. After circulating through the environmental system, different layers are analyzed respectively, which can comprehensively understand soil quality, pollution status and environmental characteristics, provide scientific basis for soil management, project construction and environmental protection, contribute to the realization of sustainable agriculture and the protection and improvement of the ecological environment, provide factual basis for soil sample analysis and evaluation, and serve as an important indicator for judging the degree of soil environmental pollution. It provides data reference for historically similar plots, and provides basis for regulatory authorities.

1. Data source: Soil sampling and testing were conducted in accordance with the standard Soil and Sediment—Determination of Semi-Volatile Organic Compounds—Gas Chromatography-Mass Spectrometry (HJ 834-2017).

2. Algorithm rules: The calculation is performed according to the following formula:
Sample concentration = (Sample curve-found value W - Blank curve-found value) × Constant volume V × Dilution multiple D / Sampling mass m / (Dry matter content w / 100)
The unit of sample concentration is mg/kg; the units of sample curve-found value and blank curve-found value are μg/mL; the unit of constant volume is mL; the unit of sampling mass is g; the unit of dry matter content is %.

3. Data judgment: The judgment is made according to the Risk Screening Values for Land Use Category 1 specified in the Technical Standard for Risk Control of Soil Contamination in Construction Land (Trial Implementation) (GB36600-2018). If the concentration of Benzo(a)anthracene is ≤5.5 mg/kg, the soil is judged to meet the standard for this indicator; otherwise, it is judged to exceed the standard.

4. Data application: By analyzing the concentration of Benzo(a)anthracene in soil, we can determine the compliance status of Benzo(a)anthracene in the soil, avoid soil pollution caused by the high concentration of this indicator, and provide a basis for supervision.
