台州市椒江区JJZ132、JJZ161土壤中六价铬检测数据

随着工业化、城市化、农业集约化进程的加快，人们在利用土地资源进行生产生活的同时，工业三废的排放、矿山开采中的重金属污染、城市生活垃圾填埋以及农业面源污染等途径都对土壤生态环境造成了巨大的危害。土壤重金属污染可导致土壤生物多样性丢失、土地质量退化，重金属的传递甚至威胁到人类的生命安全。通过采集和分析台州市椒江分区JJZ132、JJZ161土壤中的不同层次土壤六价铬数据，可以全面了解土壤的性质、质量、污染状况和环境特征，为土壤管理、农业生产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。1、数据来源:按照土壤质量 铅、镉的测定 石墨炉原子吸收分光光度法 GB/T 17141-1997对土壤进行土壤样品采集检测。2、算法规则: 按照如下公式进行计算:W=(C-C0)*V*D/(m*Wdm*1000)，式中W为样品中六价铬的质量浓度，单位mg/kg；C:从校准曲线上查得相应测定元素的浓度(mg/L)；C0：试剂空白溶液测定浓度（mg/L）；m:称取试样的质量(g)；Wdm:试样的干物质含量；V:样品定容体积,mL；D:稀释倍数。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，若六价铬≤3.0mg/kg，则判定合格；若六价铬＞3.0mg/kg，则判定为不合格。4、数据应用：通过分析样品中六价铬的质量浓度，我们可以判断该土壤的污染程度，避免因六价铬浓度含量超高引起的土壤污染问题，为监管提供依据。

With the accelerated progress of industrialization, urbanization and agricultural intensification, while humans utilize land resources for production and daily life, the discharge of industrial waste gas, wastewater and industrial solid waste, heavy metal pollution during mining, municipal domestic waste landfill and agricultural non-point source pollution have caused enormous harm to the soil ecological environment. Soil heavy metal pollution can lead to the loss of soil biodiversity and land quality degradation, and the transmission of heavy metals even threatens human life safety. By collecting and analyzing hexavalent chromium data of soils at different soil horizons from sampling sites JJZ132 and JJZ161 in Jiaojiang District, Taizhou City, we can comprehensively understand the properties, quality, pollution status and environmental characteristics of the soil, providing scientific basis for soil management, agricultural production and environmental protection, which contributes to the protection and improvement of sustainable agriculture and ecological environment. 1. Data Source: Soil samples were collected and tested in accordance with the standard *Soil quality — Determination of lead and cadmium — Graphite furnace atomic absorption spectrometry* (GB/T 17141-1997). 2. Algorithm Rules: The calculation is performed using the following formula: $W=(C-C_0) imes V imes D/(m imes W_{dm} imes 1000)$, where $W$ is the mass concentration of hexavalent chromium in the sample, with the unit of mg/kg; $C$ is the concentration of the measured element obtained from the calibration curve (mg/L); $C_0$ is the concentration measured in the reagent blank solution (mg/L); $m$ is the mass of the weighed test sample (g); $W_{dm}$ is the dry matter content of the test sample; $V$ is the constant volume of the sample after dilution (mL); $D$ is the dilution factor. 3. Data Judgment: The judgment is conducted based on the risk screening values for the first category of construction land stipulated in the *Standard for Risk Control of Soil Contamination in Construction Land (for Trial Implementation)* (GB36600-2018). The soil is judged as qualified if the hexavalent chromium concentration ≤ 3.0 mg/kg, and unqualified if the hexavalent chromium concentration > 3.0 mg/kg. 4. Data Application: By analyzing the mass concentration of hexavalent chromium in the samples, we can assess the pollution degree of the soil, prevent soil pollution issues caused by excessive hexavalent chromium concentration, and provide scientific support for environmental supervision and management.
