大米镉含量检测数据

对市场上的大米进行抽样检测，检测项目为大米的镉含量，镉是其食品安全的重要指标，从而为大米质量分析评价提供事实依据。算法：数据采集，采集市场上的大米进行镉含量检测。数据判定:若镉含量实测值不大于0.2mg/kg，则该大米镉含量为合格，X=(C1-C0)×V/(m×1000）,公式中X为大米镉含量，mg/kg，C1为试样消化液镉含量 ng/mL，C0为空白液中镉含量 ng/mL，V为试样消化液定容体积 mL，m为试样质量 g。A sampling inspection was conducted on rice available on the market, with the detection item being cadmium content in rice, which is a critical indicator for food safety, to provide factual evidence for the analysis and evaluation of rice quality. Algorithm: Data collection: collect rice samples from the market for cadmium content detection. Data determination: If the measured cadmium content is no more than 0.2 mg/kg, the cadmium content of the rice sample is deemed qualified. The calculation formula is: X=(C1-C0)×V/(m×1000), where X represents the cadmium content in rice (unit: mg/kg), C1 is the cadmium content in the sample digestion solution (unit: ng/mL), C0 is the cadmium content in the blank solution (unit: ng/mL), V is the constant volume of the sample digestion solution (unit: mL), and m is the mass of the test sample (unit: g).
