- Abstract
Herbal plants are considered natural pharmaceuticals but also accumulate chemical elements and compounds at high levels. 210Po and 210Pb are highly radiotoxic and may cause carcinogenesis due to ionizing radiation. Thirteen of the most popular wild‐growing herbaceous plant species, mostly included in the European Pharmacopoeia, were collected across Ukraine. 210Po and 210Pb were determined in the medicinal plants, and their radiotoxicity and cancer risk were calculated. The results of 210Po activities measured in herbal raw material ranged from 2.28 Bq kg−1 dw (where dw is dry weight) in herb of common horsetail (Equisetum arvense L.) collected near Lviv to 37.7 Bq kg−1 dw in leaves of common birch (Betula pendula Roth.) from Rava Ruska. The activity concentrations of 210Pb varied from 0.44 Bq kg−1 dw in leaves of common birch from Starokostyantyniv to 28.4 Bq kg−1 dw in leaves of common birch from Mizhhirya. There were statistically significant differences between 210Po and 210Pb content in flowers, leaves, and aerial portions. The studies indicated that the estimated annual effective radiation dose from Ukrainian herbs consumption was low, ranging 5.00–82.6 µSv from 210Po and 0.56–35.8 µSv from 210Pb, while the cancer morbidity and mortality risk ranged from 10−4 to 10−6. The presented data indicated no radiological risk related to using herbal plant materials. Core Ideas: 210Po and 210Pb are present in Ukrainian herbal drugs.Medicinal plants' leaves contained the biggest amount of 210Po and 210Po.The highest 210Po and 210Pb content was in common birch (Betula pendula).Ukrainian herbal plants can be considered safe in the case of 210Po and 210Po. Plain Language Summary: Herbal plants are considered natural pharmaceuticals but also accumulate chemical elements and compounds at high levels. The idea of the study was to measure radioactive 210Po and 210Pb in herbal plants and then assess their radiotoxicity and cancer risk. The presented data indicated no radiological risk related to using herbal plant materials.
