黑木耳铅含量检测数据

对市场中的黑木耳进行抽样检测，检测项目黑木耳中重金属铅的含量，铅含量是该产品安全的一项重要指标，从而为黑木耳质量分析评价提供事实依据算法：数据采集，随机抽取黑木耳产品，对该成品进行铅含量检测。数据判定：铅含量不大于1.0mg/kg，则该成品为合格，X=C×V×F/（m×1000），公式中X为试样中铅的含量，单位mg/kg; C 为样品浓度，单位μg/L；V为定容体积，单位mL；m为称样量或取样量，单位g；F为稀释倍数。

A sampling inspection was carried out on black fungus products available in the market, with the content of heavy metal lead in the products as the detection item. Lead content serves as a critical indicator for the safety of this product, providing factual evidence for the quality analysis and evaluation of black fungus.
Testing Workflow: For data collection, randomly sample black fungus products and perform lead content detection on the finished products.
Data Judgment: The finished product is deemed qualified if its lead content does not exceed 1.0 mg/kg. The calculation formula is X = (C × V × F) / (m × 1000), where X is the lead content in the test sample, with the unit of mg/kg; C is the sample concentration, with the unit of μg/L; V is the constant volume, with the unit of mL; m is the sample weighing amount or sampling quantity, with the unit of g; F is the dilution factor.
