带鱼中镉含量安全评价检测数据

数据用途和场景：为保证带鱼的安全性，需要对带鱼镉含量进行把控。《食品安全国家标准食品中污染物限量》（GB 2762—2017）中规定，带鱼最高限量值为0.1mg/kg。本数据主要用于监测温岭松门水产批发市场流通领域带鱼镉含量指标的情况，为监管部门提供监管依据。1.数据采集：数据采集于温岭松门水产批发市场的抽检样品；2.本数据主要用于监测流通领域带鱼镉含量指标的情况，为监管部门提供监管依据。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-C1)*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)；C1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值为定值；1000为换算系数 。可得检查项目镉的含量数据。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 ensure the food safety of hairtail, the cadmium content in hairtail must be strictly controlled. As stipulated in the National Food Safety Standard Limits of Contaminants in Foods (GB 2762—2017), the maximum permissible cadmium limit for hairtail is 0.1 mg/kg. This dataset is primarily designed to monitor the cadmium content of hairtail in circulation at Wenling Songmen Aquatic Product Wholesale Market, providing scientific regulatory basis for relevant supervision departments.

1. Data Collection: All data in this dataset are sourced from randomly sampled products at Wenling Songmen Aquatic Product Wholesale Market.

2. Data Calculation: This dataset is mainly used to monitor the cadmium content of hairtail in circulation to provide regulatory support for supervision authorities. The detection values of sampled products from the local market are calculated via the following formula:
X=(C-C1)*V*f/m/1000
Where:
- X: Content of the target component in the test sample, unit: milligrams per kilogram (mg/kg)
- C: Cadmium concentration in the sample test solution, unit: micrograms per liter (μg/L)
- C1: Cadmium concentration in the reagent blank solution, unit: micrograms per liter (μg/L)
- V: Constant volume of the sample test solution, unit: milliliters (mL)
- m: Mass of the test sample, unit: grams (g)
- f: Fixed value
- 1000: Unit conversion coefficient
The cadmium content data for the detection item can thus be obtained.

3. Data Analysis: The collected detection data are compared against the technical requirements specified in the national standard GB 5009.15-2014 National Food Safety Standard Determination of Cadmium in Foods. Samples with cadmium content within the stipulated limit are qualified, while those exceeding the limit are unqualified.
