Assessment of cancer risk and radiological effects from Po and Pb with consumption of wild medicinal herbal plants.

Background: Plants' raw materials can accumulate chemical elements, including radioisotopes, to some extent and reflect the region they grow in. Due to their high environmental content and toxicity, natural radionuclides - polonium Po and lead Pb are the most dangerous radioisotopes for human health.

Methods: 70 raw medicinal herbal materials from 54 popular wild-growing medicinal plant species, most of them included in the European Pharmacopoeia, were collected across three regions.

The presence of radiotoxic Po and Pb in Ukrainian wild medicinal plants and the assessment of related dose and cancer risk.

Herbal plants are considered natural pharmaceuticals but also accumulate chemical elements and compounds at high levels. Po and Pb 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.

On the radiotoxic Po in coffee beans worldwide and the impact of roasting and brewing on its extraction into beverages: from the experiments to Po content prediction.

We determined radiotoxic Po in roasted coffee beans from different regions worldwide, the beverages, and tried to create the prediction model of Po content based on its growth location. Additionally, the experiments on Po losses and extraction were performed to describe the actual exposure to Po. Po concentrations in coffee beans and brews tuned out low (maximally of 0.

On Po and Pb in algae diet supplements - The assessed radiation hazard of aquatic superfoods.

Algae are believed to give health benefits. However, the studies showed they contain toxic elements, including radionuclides, and may affect human health. The study presents the values of activity concentrations of Po and Pb in the algae supplements available worldwide for adults.

On the occurrence, origin, and intake of the nuclides, Po and Pb, in sclerotia of Wolfiporia cocos collected in China.

The dried sclerotium of the fungus Wolfiporia cocos is edible and has medicinal value. This study aimed to understand the accumulation of radioactivity arising from the alpha Po, and beta-emitting Pb, in the sclerotium's shell and core and assess a potential effective dose for consumers. Sclerotia were collected in the wild and from cultivars in China's Anhui and Yunnan provinces.

Po and Pb in King Bolete () and Related Mushroom Species: Estimated Effective Radiation Dose and Geospatial Distribution in Central and Eastern Europe.

Po and Pb occur naturally and are the most radiotoxic isotopes of the uranium (U) decay chain. Samples of and related mushroom species, including , , and , collected from Poland and Belarus were investigated for the activity concentrations of these isotopes and also for their potential health risk through adult human consumption. The results showed that spatially, the occurrence of Po and Po was heterogeneous, with activities varying from 0.

Bolete mushroom Boletus bainiugan from Yunnan as a reflection of the geographical distribution of Po, Pb and uranium (U, U, U) radionuclides, their intake rates and effective exposure doses.

This pioneering study aimed to determine the activity concentrations of Po, Pb and uranium (U, U, U) radionuclides in fruit bodies of wild bolete Boletus bainiugan Dentinger and to estimate its edible safety, which may give scientific evidence for the consumption of this species. The analyses were performed using alpha spectrometer after digestion, exchange resins separation and deposition. Measurement data were analysed and interpolation maps reflecting Po, Pb and uranium (U, U, U) geographical distribution in Yunnan province (China) were presented.

The level of Pb extraction efficiency in Polish herbal teas and the possible effective dose to consumers.

The article presents the results of a study on the level of Pb efficiency extraction in Polish herbal teas as a possible additional source of this radioactive isotope in the human diet. The twelve most popular herbal teas available in Poland and their infusions in filtered and tap water were analyzed as well as Pb activity concentrations and effective doses (radiation) were calculated. The highest activity concentration of Pb in dried plants was determined in cistus - 35.

On uranium U and U radionuclides in calcium and magnesium supplements and the potential effective radiation dose assessment to the consumers.

In this survey the concentrations of the radioactive nuclides uranium U and U were determined in the most popular calcium and magnesium supplements for adults in Poland. It was also investigated whether the supplements contain uranium isotopes and could be a potential source in the human diet and have an influence on the value of effective radiation doses to the consumers. The analyzed calcium and magnesium pharmaceuticals contained organic or inorganic compounds, several of natural origin as mussel's shells, fish extracts, or sedimentary rocks.
