时令蔬菜甲拌磷含量安全监测分析数据

蔬菜在生长过程中会喷洒农药来杀虫，为了避免食品安全事故发，本数据得出样品中甲拌磷残留含量的结果，检测数据按照GB 23200.8-2016《食品安全国家标准 水果和蔬菜中500种农药及相关化学品残留量的测定 气相色谱-质谱法》的要求进行检测，按照GB 2763《食品安全国家标准 食品中农药最大残留限量》进行判定，可得出该样品是否合格。该项数据关乎消费者食品安全，为政府监管、消费者购买提供参考和技术支撑，有着不可忽视的重要性。1、.数据采集:采集时令蔬菜样品名称、检测项目等信息；2、检测算法：按照标准GB 23200.8-2016《食品安全国家标准 水果和蔬菜中500种农药及相关化学品残留量的测定 气相色谱-质谱法》对样品进行检测，检测值按照如下公式进行计算: X=(C*V*f)/(m*1000)，式中X为试样中待测组分的含量，单位为毫克每千克（mg/kg); C为标准曲线得出的试样液中待测物的质量浓度，单位为微克每千克（ug/kg); V为取得1/5提取液后定容体积，单位为（mL); m为试样质量，单位为克(g); f为稀释因子 (本方法为5）；1000为换算系数。可得到检查项目的含量数据。3、数据分析：将含量数据按照GB 2763《食品安全国家标准 食品中农药最大残留限量》进行判定，在限定值内的为符合，超出限定值的为不符合，用于评估其食用安全性。4、算法规则：时令蔬菜甲拌磷问题发现率=检出问题项次数/样品总数。

During the growth of vegetables, pesticides are sprayed for pest control. To prevent food safety incidents, this dataset provides the results of phorate residue content in tested samples. The detection data is generated in strict accordance with the requirements of GB 23200.8-2016, National Food Safety Standard of China: Determination of 500 Pesticides and Related Chemical Residues in Fruits and Vegetables by Gas Chromatography-Mass Spectrometry (GC-MS), and the qualification of the samples is judged based on GB 2763, National Food Safety Standard of China: Maximum Residue Limits of Pesticides in Foods. This dataset is critical to consumer food safety, offering reference and technical support for government supervision and consumer purchasing decisions, with indispensable importance.
1. Data Collection: Collect information including the names of seasonal vegetable samples and testing items;
2. Testing Algorithm: Conduct tests on the samples according to GB 23200.8-2016, National Food Safety Standard of China: Determination of 500 Pesticides and Related Chemical Residues in Fruits and Vegetables by Gas Chromatography-Mass Spectrometry (GC-MS). The detection values are calculated using the following formula: X=(C*V*f)/(m*1000), where X represents the content of the analyte in the sample, with the unit of milligrams per kilogram (mg/kg); C is the mass concentration of the analyte in the sample solution derived from the standard curve, with the unit of micrograms per kilogram (μg/kg); V is the final constant volume after taking 1/5 of the extract, with the unit of milliliters (mL); m is the mass of the test sample, with the unit of grams (g); f is the dilution factor (set to 5 in this method); 1000 is the unit conversion factor. The content data of each test item can thus be obtained.
3. Data Analysis: Evaluate the content data against GB 2763, National Food Safety Standard of China: Maximum Residue Limits of Pesticides in Foods. Samples with residue levels within the specified limits are deemed qualified, while those exceeding the limits are unqualified, which serves to assess their edible safety.
4. Algorithm Rules: Seasonal vegetable phorate problem detection rate = Number of detected problematic items / Total number of samples.
