坚果百菌清含量安全监测分析数据

百菌清是一种高效、广谱、保护性杀菌剂，常用于防治果树、蔬菜菜叶等多种害虫，同时对水稻、小麦、棉花等多种农作物病害，也有防治效果。本数据可以对坚果中百菌清含量安全监测分析数据情况进行安全性评价，为政府监管和消费者购买提供参考和技术支撑。1、百菌清按如下公式进行计算：X=c*V/m，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，单位为微克每毫升（ug/mL）；V为总体积，单位为毫升（mL）;m为样品溶液所代表试样的质量，单位为克（g）。2、数据分析：将以上数据按照GB 2763-2021《食品安全国家标准 食品中农药最大残留量》要求，最大残留限量＜0.3mg/kg，在最大允许限值范围内的为符合，超最大允许限值的为不符合。

Chlorothalonil is a high-efficiency, broad-spectrum protective fungicide. It is commonly used to control various pests on fruit trees, vegetables and leafy vegetables, and also effective against diseases of multiple crops including rice, wheat and cotton. This dataset can be used to conduct safety assessment on the safety monitoring and analysis data of chlorothalonil content in nuts, providing reference and technical support for government supervision and consumer purchasing decisions. 1. Chlorothalonil content is calculated by the following formula: X = c * V / m, where: X is the content of the component to be detected in the sample, with the unit of milligrams per kilogram (mg/kg); c is the mass concentration of the analyte in the sample solution obtained from the standard curve, with the unit of micrograms per milliliter (μg/mL); V is the total volume, with the unit of milliliters (mL); m is the mass of the sample represented by the sample solution, with the unit of grams (g). 2. Data analysis: According to the requirements of GB 2763-2021 *National Food Safety Standard Maximum Residue Limits of Pesticides in Foods*, the maximum residue limit (MRL) is <0.3 mg/kg. Samples with chlorothalonil content within the maximum allowable limit are considered compliant, while those exceeding the limit are deemed non-compliant.
