台州市椒江分区JJZ132、JJZ161土壤中铬检测数据

铬及其化合物所引起的环境污染。主要来源于劣质化妆品原料、皮革制剂、金属部件镀铬部分，工业颜料以及鞣革、橡胶和陶瓷原料等。分别分析不同层的铬，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：土壤和沉积物 铜、锌、铅、镍、铬的测定 火焰原子吸收分光光度法 HJ 491-2019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W=(样品查曲线值C-空白查曲线值C0)*定容体积V*稀释倍数D/(取样量m*试样中干物质含量Wdm)，公式中W为样品浓度单位为mg/kg；样品查曲线值及空白查曲线值单位为mg/L；定容体积单位为mL；取样量单位为g。3、数据判定：根据《污染场地风险评估技术导则》（DB 33/T 892-2013）进行判定，若铬浓度数据≤250mg/kg，则判定土壤中该指标浓度达标，反之则超标。4、数据应用：通过分析土壤中铬的浓度，我们可以判断该土壤中铬的达标情况，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。

Chromium and its compounds induce environmental pollution, whose main sources include low-quality cosmetic raw materials, leather preparations, chrome-plated components of metal parts, industrial pigments, as well as tanning, rubber and ceramic raw materials, etc. Analyzing chromium concentrations in different soil layers enables comprehensive understanding of soil quality, pollution status and environmental characteristics, providing scientific basis for soil management, project construction and environmental protection. It supports the achievement of sustainable agriculture and the protection and improvement of the ecological environment. The factual data derived from soil sample analysis and evaluation serves as a critical indicator for judging the degree of soil environmental pollution, provides data references for plots with similar historical conditions, and offers support for regulatory authorities. 1. Data Source: Soil samples were collected and tested in accordance with the standard "Determination of Copper, Zinc, Lead, Nickel and Chromium in Soils and Sediments by Flame Atomic Absorption Spectrophotometry" (HJ 491-2019). 2. Algorithm Rules: The calculation is conducted using the following formula: $W = (C - C_0) * V * D / (m * W_{dm})$, where $W$ represents the sample concentration with the unit of mg/kg; $C$ is the calibration curve-derived value of the sample, $C_0$ is the calibration curve-derived value of the blank, both with the unit of mg/L; $V$ is the constant volume with the unit of mL; $m$ is the sampling mass with the unit of g; $W_{dm}$ is the dry matter content in the test sample. 3. Data Judgment: The judgment is made according to the "Technical Guidelines for Risk Assessment of Contaminated Sites" (DB 33/T 892-2013). If the chromium concentration is ≤250 mg/kg, the concentration of this indicator in the soil is deemed to meet the standard; otherwise, it exceeds the standard. 4. Data Application: By analyzing the chromium concentration in soil, we can determine the compliance of chromium in the soil, avoid soil pollution caused by excessive concentration of this indicator, and provide support for regulatory supervision work.
