“…Variations in the values of the ELCR due to ingestion of fruits are due to the different conversion factors for different age category. This is in agreement with Priharti, et al [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Also the internal hazard index for all the fruits from different states in Niger Delta showed that the internal hazard due to Apricot is very high.…”

Determination of radionuclides’ activity concentration in fruits is essential for the protection of human health. Fruits can be radioactive due to the present of naturally occurring radioactive materials (NORMs) and technically enhanced radioactive materials (TENORMs) in the environment. The Assessment of Radionuclide activity concentration in Some Fruits from Niger Delta, Nigeria and its Health Risks were carried out using gamma ray spectroscopy. The study measured the activity concentration of radionuclides in fruits and the results showed that the total activity concentration of 40K, 232Th and 226Ra in fruits were 578.24 Bqkg-1, 263.84 Bqkg-1 and 128.35 Bqkg-1 respectively. The study found out that 40K has the highest value of activity concentration while apricot has the highest value of radionuclide concentration compared to other fruits. The statistical analysis of data was also done using statistical packages. The average estimated AED for Infants, Children and Adults due to the radioactivity in Avocado, Apricot, Guava and Pear were; 829.02 µSvy-1, 565.865 µSvy-1, and 838.725 µSvy-1, 2737.665 µSvy-1, 4361.4875 µSvy-1 and 2497.9025 µSvy-1, 651.20833 µSvy-1, 1202.6767 µSvy-1 and 813.22167 µSvy-1, and 1164.7883 µSvy-1, 1724.2933 µSvy-1 and 1088.8933 µSvy-1 respectively. The estimated AED due to the consumption of various fruits are above the world value. However, the estimated excess lifetime cancer risks for the various fruits are far below the world (WHO) limit. The study concluded that there is no cancer risk associated with the consumption of fruits in the study area and that the fruits that have tap root systems recorded highest value of radionuclides’ activity concentration.

“…Usually, the US-EPA considers cancer risks that are bellow 1 × 10 -6 , to be so small as to be negligible and risks above 1 × 10 -4 to be adequately large that some sort of remediation is desirable. Cancer risks that range between 1 × 10 -6 and 1 × 10 -4 are generally considered to be acceptable [ 56 , 57 ]. Therefore, from the calculated values obtained in this study, the seafood-consuming populace may be at considerable risk.…”

BackgroundPo210 can be accumulated in various environmental materials, including marine organisms, and contributes to the dose of natural radiation in seafood. The concentration of this radionuclide in the marine environment can be influenced by the operation of a coal burning power plant but existing studies regarding this issue are not well documented. Therefore, the aim of this study was to estimate the Po210 concentration level in marine organisms from the coastal area of Kapar, Malaysia which is very near to a coal burning power plant station and to assess its impact on seafood consumers.MethodsConcentration of Po210 was determined in the edible muscle of seafood and water from the coastal area of Kapar, Malaysia using radiochemical separation and the Alpha Spectrometry technique.ResultsThe activities of Po210 in the dissolved phase of water samples ranged between 0.51 ± 0.21 and 0.71 ± 0.24 mBql-1 whereas the particulate phase registered a range of 50.34 ± 11.40 to 72.07 ± 21.20 Bqkg-1. The ranges of Po210 activities in the organism samples were 4.4 ± 0.12 to 6.4 ± 0.95 Bqkg-1 dry wt in fish (Arius maculatus), 45.7 ± 0.86 to 54.4 ± 1.58 Bqkg-1 dry wt in shrimp (Penaeus merguiensis) and 104.3 ± 3.44 to 293.8 ± 10.04 Bqkg-1 dry wt in cockle (Anadara granosa). The variation of Po210 in organisms is dependent on the mode of their life style, ambient water concentration and seasonal changes. The concentration factors calculated for fish and molluscs were higher than the recommended values by the IAEA. An assessment of daily intake and received dose due to the consumption of seafood was also carried out and found to be 2083.85 mBqday-1person-1 and 249.30 μSvyr-1 respectively. These values are comparatively higher than reported values in other countries. Moreover, the transformation of Po210 in the human body was calculated and revealed that a considerable amount of Po210 can be absorbed in the internal organs. The calculated values of life time mortality and morbidity cancer risks were 24.8 × 10-4 and 34 × 10-4 respectively which also exceeded the recommended limits set by the ICRP.ConclusionsThe findings of this present study can be used to evaluate the safety dose uptake level of seafood as well as to monitor environmental health. However, as the calculated dose and cancer risks were found to cross the limit of safety, finding a realistic way to moderate the risk is imperative.

“…Based on highlights of the study Hakonson-Hayes et al [92], Giri et al [93] and Hashim & Najam [94], it was found that the main way people are exposed to U toxicological and radiological ill-effects is by directly drinking contaminated groundwater, accounting for more than 85-99% of the health risks for human consumers. Considering established safety measures and relying on oral ingestion, the World Health Organization (WHO) has set a Tolerable Daily Intake (TDI) of 0.6 µg/kg body weight per day for soluble U [95].…”

Uranium (U) and fluoride (F−) contamination in agricultural products, especially vegetable and cereal crops, has raised serious concerns about food safety and human health on a global scale. To date, numerous studies have reported U and F− contamination in vegetable and cereal crops at local scales, but the available information is dispersed, and crop-wise differences are lacking. This paper reviews the current status of knowledge on this subject by compiling relevant published literatures between 1983 and 2023 using databases such as Scopus, PubMed, Medline, ScienceDirect, and Google Scholar. Based on the median values, F− levels ranged from 0.5 to 177 mg/kg, with higher concentrations in non-leafy vegetables, such as Indian squash “Praecitrullus fistulosus” (177 mg/kg) and cucumber “Cucumis sativus” (96.25 mg/kg). For leafy vegetables, the maximum levels were recorded in bathua “Chenopodium album” (72.01 mg/kg) and mint “Mentha arvensis” (44.34 mg/kg), where more than 50% of the vegetable varieties had concentrations of >4 mg/kg. The concentration of U ranged from 0.01 to 17.28 mg/kg; tubers and peels of non-leafy vegetables, particularly radishes “Raphanus sativus” (1.15 mg/kg) and cucumber “Cucumis sativus” (0.42 mg/kg), contained higher levels. These crops have the potential to form organometallic complexes with U, resulting in more severe threats to human health. For cereal crops (based on median values), the maximum F− level was found in bajra “Pennisetum glaucum” (15.18 mg/kg), followed by chana “Cicer arietinum” (7.8 mg/kg) and split green gram “Vigna mungo” (4.14 mg/kg), while the maximum accumulation of U was recorded for barley “Hordeum vulgare” (2.89 mg/kg), followed by split green gram “Vigna mungo” (0.45 mg/kg). There are significant differences in U and F− concentrations in either crop type based on individual studies or countries. These differences can be explained mainly due to changes in geogenic and anthropogenic factors, thereby making policy decisions related to health and intake difficult at even small spatial scales. Methodologies for comprehensive regional—or larger—policy scales will require further research and should include strategies to restrict crop intake in specified “hot spots”.
