诸暨市菠菜中镉含量安全评价检测数据

数据用途和场景：为保证菠菜的食用安全性，需要对菠菜流通环节镉含量进行把控。《食品安全国家标准食品中污染物限量》（GB 2762—2017）中规定，菠菜中镉的最高限量值为0.2mg/kg。本数据主要用于监测诸暨市流通领域菠菜中镉含量指标的情况，为监管部门提供监管依据。1、.数据采集：数据采集于诸暨市场的抽检样品；2、对我市市场的抽检产品的检测值按照如下公式进行计算：X=(C-C0)*V*f/m/1000，式中：X为试样中待测组分含量，单位为毫克每千克(mg/kg)；C为试样待测液中镉含量，单位为微克每升(ug/L)；C0为试剂空白液中镉含量，单位为微克每升(ug/L)；V为试样待测液定容体积 ，单位为毫升(mL)；m为试样质量 ，单位为克(g)；f为定值；1000为换算系数 。3、.数据分析：将以上检测数据对比国标GB 5009.15-2014 《食品安全国家标准 食品中镉的测定》标定的数据要求，在限定值内的为合格，超出限定值的为不合格

Data Purpose and Application Scenario: To guarantee the edible safety of spinach, the cadmium content in the circulation chain of spinach must be controlled. The "National Food Safety Standard Limits of Contaminants in Foods" (GB 2762—2017) specifies that the maximum allowable cadmium limit in spinach is 0.2 mg/kg. This dataset is primarily employed to monitor the cadmium levels of spinach in the circulation sector of Zhuji City, providing regulatory support for local supervision authorities.
1. Data Collection: All data are sourced from spot-check samples collected from markets in Zhuji City;
2. The test values of spot-checked products in the city are calculated via the following formula: X=(C-C0)×V×f/(m×1000), where:
X: Content of the target analyte in the sample, unit: milligrams per kilogram (mg/kg);
C: Cadmium concentration in the sample test solution, unit: micrograms per liter (μg/L);
C0: Cadmium concentration in the reagent blank solution, unit: micrograms per liter (μg/L);
V: Final volume of the sample test solution, unit: milliliters (mL);
m: Mass of the test sample, unit: grams (g);
f: Predefined calibration factor;
1000: Unit conversion factor.
3. Data Analysis: The obtained test data are compared against the requirements specified in the national standard GB 5009.15-2014 "National Food Safety Standard Determination of Cadmium in Foods". Samples with test values within the specified limit are classified as qualified, while those exceeding the limit are deemed unqualified.
