[PMID: 36906962 DOI: 10.1016/j.jenvrad.2023.107149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 02/24/2023] [Accepted: 03/04/2023] [Indexed: 06/18/2023]
Abstract
The soil-to-orange fruit transfer factor of naturally occurring radionuclides was investigated. The temporal evolution of the three identified radionuclides, Ra-226, Th-232, and K-40, concentration was also examined throughout the growth period of the orange fruits until they reached maturity. A mathematical model was developed to predict the soil-to-fruit transfer of these radionuclides during the development of orange fruits. The results were found to agree with the experimental data. The experimental and modeling results revealed that the transfer factor for all radionuclides showed a similar exponential decline with the growth of the fruit and reached its minimum value when the fruit was ripe.

Abstract
Medicinal plants consumed in Bitlis were analysed for 226Ra, 232Th and 137Cs using HPGe gamma spectroscopy system. Both plant samples and the corresponding soils were analysed. Using these values, the transfer factors for 226Ra, 232Th and 137Cs were calculated in the ranges of (0.09-2.18), (0.01-0.19) and (0.01-2.8), respectively. Based on the plant concentrations observed, unless consumed in excessive amounts, these medicinal plants do not have any radiological harm to health.

An In-Depth Examination of the Natural Radiation and Radioactive Dangers Associated with Regularly Used Medicinal Herbs. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19138124. [PMID: 35805783 PMCID: PMC9266100 DOI: 10.3390/ijerph19138124] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Revised: 06/11/2022] [Accepted: 06/21/2022] [Indexed: 02/04/2023]
Abstract
The specific activity of U-238 and Th-232, as well as K-40 radionuclides, in twenty-nine investigated medicinal herbs used in Egypt has been measured using a high-purity germanium (HP Ge) detector. The measured values ranged from the BDL to 20.71 ± 1.52 with a mean of 7.25 ± 0.54 (Bq kg−1) for uranium-238, from the BDL to 29.35 ± 1.33 with a mean of 7.78 ± 0.633 (Bq kg−1) for thorium-232, and from 172 ± 5.85 to 1181.2 ± 25.5 with a mean of 471.4 ± 11.33 (Bq kg−1) for potassium-40. Individual herbs with the highest activity levels were found to be 20.71 ± 1.52 (Bq kg−1) for uranium-238 (H4, Thyme herb), 29.35 ± 1.33 (Bq kg−1) for thorium-232 (H20, Cinnamon), and 1181.2 ± 25.5 (Bq kg−1) for potassium-40 (H24, Worm-wood). (AACED) Ingestion-related effective doses over the course of a year of uranium-238 and thorium-232, as well as potassium-40 estimated from measured activity concentrations, are 0.002304 ± 0.00009 (minimum), 0.50869 ± 0.0002 (maximum), and 0.0373 ± 0.0004 (average)(mSv/yr). Radium equivalent activity (Raeq), annual gonadal dose equivalent (AGDE), absorbed gamma dose rate (Doutdoor, Dindoor), gamma representative level index (I), annual effective dose (AEDtotal), external and internal hazard index (Hex, Hin), and excess lifetime cancer risk were determined in medicinal plants (ELCR). The radiological hazards assessment revealed that the investigated plant species have natural radioactivity levels that are well within the internationally recommended limit. This is the first time that the natural radioactivity of therapeutic plants has been measured in Egypt. In addition, no artificial radionuclide (for example, 137Cs) was discovered in any of the samples. Therefore, the current findings are intended to serve as the foundation for establishing a standard safety and guideline for using these therapeutic plants in Egypt.

Abstract
The activity concentrations of naturally occurring radionuclides in
vegetables and peat soil were investigated to determine the transfer factors
of radionuclides from soil to vegetables obtained from farms in Klang
Selangor. The results showed that the activity concentration ranges for
226Ra, 232Th, and 40K in the soil of the vegetable were 2.72-46.54 Bqkg-1,
9.01-54.84 Bqkg-1, and 19.22-477.76 Bqkg-1, respectively. The activity
concentration ranges for 226Ra, 232Th, and 40K in various vegetable samples
were 0.41-3.41 Bqkg-1, 0.02-3.56 Bqkg-1, and 16.22-317.49 Bqkg-1,
respectively. The transfer factors from soil-to-plant for 226Ra, 232Th, and
40K were in the ranges of 0.01-0.67, 0.00-0.17, and 0.26-2.52, respectively.
Radionuclide 40K has the highest transfer factor value in most vegetables,
especially in the fruit type vegetable, and 232Th was found to have the
lowest transfer factor value in all vegetables. The acquired results were
compared to the levels that are globally recognized as acceptable. The
transfer factor value of 40K was greater than 1 found in beans and fruit
type vegetables, showing a similar value in other studies involving tropical
plants, while transfer factor value for 226Ra was 15 times higher than the
value reported in the data for tropical plants.

Abstract
Soil to plant transfer factor (TF) of radionuclides is an important input parameter in dose assessment models. The wide range of TF for each radionuclide reported in the literature for a particular plant type indicates that radionuclide concentration in soil is not the only factor influencing its uptake by the plant. Different soil properties and agricultural practices may influence the TF and these are also a function of the climate. Considering the wide variation in TF data, here we attempt to review the available literature on TF of radionuclides in tropical countries of the Indian subcontinent (India, Bangladesh, and Sri Lanka). TF under equilibrium conditions are not available for all radionuclides, in such cases TF of naturally existing stable analogs elements were compiled. With an emphasis on, transfer of radionuclides from soil to the edible compartment of the plant; the TF data for 21 elements are compiled for 12 plant groups classified as per IAEA, Technical Reports Series No. 472. The article also presents the analysis and discussion of the extent and limitations of the compiled data. The compiled TF may be useful in assessing the food chain transfer of radionuclides when site-specific information is not available.

Abstract
Ten medicinal plants used as ingredients of folklore and Ayurvedic medicine belonging to the Malnad Kerala region of South India, were analysed for concentrations of trace elements Fe, Cr, Mn, Co, Ni, Cu, Zn, As, and Pb using the Energy Dispersive X-ray Fluorescence (EDXRF) technique. The soil from the root area of these medicinal plants was also analysed, and the soil to plant transfer factor (TF) of the elements was estimated. Iron (Fe) recorded higher concentration than the other trace elements estimated in the medicinal plants, followed by manganese (Mn) and zinc (Zn). The mean TF was found to be highest for Zn. Plectranthus amboinicus (Lour.) Spreng recorded the maximum value of TF for Zn. Most of the essential elements were found to be present in Centella asiatica (L.) Urban and indicated its medicinal importance. The data obtained in the present investigation may add up to the trace elemental database of medicinal plants in the world.

Abstract
The article presents the results of a study on the level of 210Pb 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 210Pb activity concentrations and effective doses (radiation) were calculated. The highest activity concentration of 210Pb in dried plants was determined in cistus - 35.5 Bq kg-1 dry wt, while the lowest was in milk thistle - 3.25 Bq kg-1 dry wt what gives respectively for cistus 46.1 ± 0.7 and 6.50 ± 0.29 mBq for milk thistle per one tea bag. The extraction efficiencies in the filtered water oscillated from 5.1 ± 0.5 for milk thistle to 27.3 ± 0.8% for cistus, while for the tap water they ranged from 7.3 ± 0.6% for lime to 33.3 ± 2.2% for white mulberry. Based on the study, it was found that the analyzed herbal tea consumption would give a small portion of the annual effective dose of 210Pb received in Poland - the annual effective radiation dose of 210Pb taken with herbal tea infusions (one glass daily) was calculated from 0.08 ± 0.01 to 3.17 ± 0.08 µSv.

Abstract
A soil-to-plant transfer factor (TF) is an important parameter that could be used to estimate radionuclides levels in medicinal plants. This work reports concentrations of natural radionuclides (226Ra and 40K) and TFs in six Thai medicinal plants grown in central Thailand using an HPGe gamma ray spectrometer. Either root, leaf, or flower parts of each medicinal plant were selected for use in the investigation according to their practical uses in traditional medicine. The results showed that due to K being essential in plants, 40K had higher arithmetic means of activity concentrations and geometric means of TFs (geometric standard deviations in parentheses) of 610 ± 260 Bq kg-1 dry weight (DW) and 2.0 (1.4), respectively, than 226Ra, which had the activity concentrations and TFs of 4.8 ± 2.6 Bq kg-1 DW and 0.17 (1.8), respectively. The results also showed that the leaves of medicinal plants had higher activity concentrations and TFs than root and flower parts, probably due to higher metabolic activities in leaves. Furthermore, there was good agreement between the results from the current work and other similar reports on medicinal plants. The information obtained from this work could strengthen knowledge of natural radionuclides in plants and particularly increase available TF data on Thai medicinal plants.
