Food Addit Contam Part B Surveill. 2018 Dec;11(4):302-308. doi: 10.1080/19393210.2018.1505781. Epub 2018 Aug 13.
Heavy-metal content (arsenic, cadmium, lead and mercury) was investigated and evaluated in shellfish, oysters and squids. The samples were collected weekly for 20 weeks from a fishery product market in Hungary. The concentration of heavy metals was measured by Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) analysis after sample preparation. The results were analysed statistically by one-way ANOVA method. The average concentration of arsenic (3.01 ± 1.46 mg kg) in shellfish was significantly higher (p < 0.001) compared to oysters (2.88 ± 1.12 mg kg) and squids (1.28 ± 0.52 mg kg). The level of mercury was below the limit of detection (0.5 mg kg) in each sample and there was no statistical significance in the concentrations of cadmium (p = 0.351) and lead (p = 0.412) in the species investigated. The provisional tolerable intake values were also calculated. Based on the obtained results of the heavy-metal content of the investigated samples, the seafood is considered to be safe for human consumption. However, prolonged ingestion of oysters and squids at these levels may contribute to the consumers' cadmium burden.
对贝类、牡蛎和鱿鱼中的重金属含量（砷、镉、铅和汞）进行了调查和评估。从匈牙利的一个渔业产品市场每周采集样本，持续20周。样本制备后，通过电感耦合等离子体发射光谱仪（ICP - OES）分析测量重金属浓度。结果采用单因素方差分析方法进行统计分析。贝类中砷的平均浓度（3.01±1.46毫克/千克）显著高于牡蛎（2.88±1.12毫克/千克）和鱿鱼（1.28±0.52毫克/千克）（p<0.001）。每个样本中的汞含量均低于检测限（0.5毫克/千克），在所研究的物种中，镉（p = 0.351）和铅（p = 0.412）的浓度没有统计学意义。还计算了暂定可耐受摄入量值。根据所研究样本的重金属含量结果，这些海鲜被认为可供人类安全食用。然而，长期摄入这些水平的牡蛎和鱿鱼可能会增加消费者的镉负担。
