In this study, the activity concentrations levels of Pb and Po in the edible portions of eight seafood samples collected from the Fujian coast of China were determined. The activity concentrations ranged from 0.74 ± 0.08 to 12.6 ± 1.0 Bq/kg for Po and from the minimum detectable limit (MDL, 0.80 Bq/kg) to 11. 7 ± 1.1 Bq/kg for Pb. The Po activity concentration in all the fish organs ranged from 0.68 to 204 Bq/kg (), and the Po activity was mainly concentrated in the stomach, spleen, heart, liver, gonad, and intestine samples. The Pb activity concentration in all the fish organs ranged from the MDL to 15.2 Bq/kg (), and the Pb activity was concentrated in the head, fish scale, and gill samples. The annual effective ingestion doses ranged from 82.8 to 255 μSv/a for all age groups, and the lifetime risk of cancers were estimated. Both the effective ingestion doses and cancer risk to humans were within the acceptable ranges.
在这项研究中，测定了从中国福建沿海采集的 8 种海鲜可食用部分中 Pb 和 Po 的活度浓度水平。Po 的活度浓度范围为 0.74 ± 0.08 至 12.6 ± 1.0 Bq/kg，而 Pb 的活度浓度范围为可检测下限（MDL，0.80 Bq/kg）至 11.7 ± 1.1 Bq/kg。所有鱼器官中的 Po 活度浓度范围为 0.68 至 204 Bq/kg（），Po 主要集中在胃、脾、心、肝、性腺和肠组织样本中。所有鱼器官中的 Pb 活度浓度范围为 MDL 至 15.2 Bq/kg（），Pb 主要集中在鱼头、鱼鳞和鱼鳃组织样本中。所有年龄组的年有效摄入量范围为 82.8 至 255 μSv/a，同时估算了癌症终生风险。人类的有效摄入量和癌症风险均在可接受范围内。
