Lead (Pb) and cadmium (Cd) in functional health foods (FHF) and Korean herbal medicines (KHM) were analysed by the standard addition method with inductively coupled plasma-mass spectrometry. A total of 672 samples were collected from 2347 people (1015 adults, 557 students and 775 infants and children) who lived in Korea. Pb and Cd concentrations were analysed in the samples (FHF, n = 535; KHM, n = 50). Method validation was carried out using standard reference material (SRM), recovery rate and limits of detection and quantification. Recovery rates for Pb and Cd using three SRMs were 94.9%-101.6% and 96.7%-115.2%, respectively. Mean Pb values in FHF and KHM were 0.146 and 0.349 mg kg⁻¹, respectively. Mean Cd levels in FHF and KHM were 0.035 and 0.056 mg kg⁻¹, respectively. Mean values in Spirulina and yeast products were the highest in the FHF samples (0.940 mg kg⁻¹ for Pb in Spirulina products and 0.115 mg kg⁻¹ for Cd in yeast products).
采用电感耦合等离子体质谱法（ICP-MS）的标准加入法对功能性保健品（FHF）和韩国草药（KHM）中的铅（Pb）和镉（Cd）进行了分析。从居住在韩国的 2347 人（1015 名成年人、557 名学生和 775 名婴儿和儿童）中采集了 672 个样本。对这些样本（FHF，n=535；KHM，n=50）进行了 Pb 和 Cd 浓度分析。采用标准参考物质（SRM）、回收率和检出限和定量限对方法进行了验证。使用三种 SRM 进行的 Pb 和 Cd 的回收率分别为 94.9%-101.6%和 96.7%-115.2%。FHF 和 KHM 中的 Pb 平均值分别为 0.146 和 0.349 mg kg⁻¹。FHF 和 KHM 中的 Cd 水平平均值分别为 0.035 和 0.056 mg kg⁻¹。在 FHF 样本中，螺旋藻和酵母产品中的平均值最高（螺旋藻产品中 Pb 的平均值为 0.940 mg kg⁻¹，酵母产品中 Cd 的平均值为 0.115 mg kg⁻¹）。
