Summary: The study evaluated the ionising radiation dose for New Zealanders from Po-210 in shellfish, finding that the majority did not exceed the reference level of 1000 mu Sv, indicating no cause for concern. However, over half of high shellfish consumers in areas with elevated Po-210 activity concentrations were exposed to ionising radiation higher than 1000 mu Sv annually. Exposure assessments for various demographic groups showed that higher shellfish consumption rates among those identifying as Maori led to higher doses of ionising radiation for this group.

Summary: This study aimed to understand the accumulation of radioactivity in the dried sclerotium of Wolfiporia cocos and assess the potential effective dose for consumers. The research found that the intake of W. cocos sclerotia would not significantly change the effective radiation doses, indicating that the consumption appears to be safe from a radiological protection point of view.

Summary: This study investigates the activity concentrations of polonium-210 (Po-210) in the tissues of 16 fish species from the Aegean Sea and Sea of Marmara. The results show that Po-210 accumulates prominently in the digestive tract and liver, while muscle tissue displays lower concentrations. Wild fish have higher Po-210 concentrations compared to farmed specimens. The increasing consumption of seafood from aquaculture seems to reduce radiation exposure to Po-210 in the human diet, which is beneficial to public health.

Summary: A modelling approach was used to estimate the exposure to deoxynivalenol (DON) in the Portuguese population, showing that a fraction of the population might exceed the Tolerable Daily Intake, especially children and adolescents. These results provide important contributions to understand the exposure to this mycotoxin in Portugal and assess potential public health consequences.

Summary: By comparing food intake data from the US and The Netherlands, it was found that risk assessment outcomes for 20% of food groups containing 14 allergenic foods differed considerably depending on the assumed allergen concentration. This suggests that food intake data from the US and The Netherlands cannot be used interchangeably for risk assessment.

Summary: The sixth Total Diet Study (TDS) of China conducted a nationwide study to evaluate the health effects of MSG. The study analyzed 168 samples from seven food categories of the typical Chinese daily diet to determine MSG content, consumption patterns, and associated risks. The study found that the highest MSG level in the Chinese population's daily diet was 8.63 g/kg. By combining food consumption and MSG content measurements, the estimated MSG intake for the general population of China was 17.63 mg/kg bw/d, while the apparent consumption alone resulted in an overestimated intake of 40.20 mg/kg bw/d due to the omission of MSG loss during cooking. The study also compared and analyzed MSG content, food category contributions, and ingestion levels across different nations to provide a global perspective. Furthermore, a realistic, logical, and precise risk assessment protocol for daily MSG intake was developed in this article.

Summary: This study indicates that current alcohol drinkers, especially in men, have a higher risk of gastric cancer compared to non-drinkers. The risk of gastric cancer in men is associated with higher alcohol consumption frequency and amount of ethanol intake. Frequent intake of alcohol, even in low quantities, is found to increase the risk of gastric cancer. Further research is needed to explore the detailed relationship between alcohol consumption and gastric cancer risk.

Summary: This paper focuses on the potential safety issue of highly radiotoxic radionuclide Po-210 production in the water-cooled lithium lead (WCLL) breeding blanket design of the nuclear fusion DEMO reactor proposed by the EUROfusion consortium. The Po-210 concentration in the PbLi circuit was assessed using a modified version of Bateman's equations and a one-dimensional convective fluid-dynamic model. Nuclear quantities were evaluated using Monte Carlo neutron transport analyses, and sensitivity analyses were performed to assess uncertainties in radiative-capture cross section and initial concentration of Bi-209 impurity. The results and safety implications of a PbLi accident leak were discussed.

Summary: The study found that soot in the northeastern South China Sea primarily originates from sediment resuspension on the shelf/slope, with increasing concentrations observed in the twilight zone. Export flux of soot from the euphotic zone was calculated using Po-210 deficits, showing the importance of sediment as a source of soot in the region. Coupling sediment-derived soot and Po-210-derived POC fluxes revealed a Martin Curve-like flux attenuation in the twilight zone, suggesting the potential for soot to constrain in situ POC fluxes and transport.

Summary: This review outlines the recent advancements in MP analysis and its toxicity to soil organism, Eisenia fetida. It reveals that E. fetida is more sensitive to MP exposure than other earthworm species, and highlights the limited research attention on polypropylene. The review also discusses future prospects such as the need for rapid detection techniques and investigations into co-exposure scenarios.

Summary: This study presents the concentrations of Po-210 radionuclide in various marine organisms from the northern part of the Sea of Marmara in 2019. The deposition of Po-210 in different species on different metal discs was investigated, and the disc with the highest deposition yield was determined. The specific activity and ingestion doses from consuming these marine species were also calculated.

Summary: This paper suggests that the origin of the LNT concept for ionizing radiation was based on a lack of understanding of evolution, leading to the establishment of the linear no threshold dose response model. However, modern advancements in repair mechanisms have shown that the historical foundations of LNT were flawed.

Summary: The study evaluated the levels of Hg and Po-210 in commercially important fish species collected along the Djiboutian coast, revealing that the concentrations exceeded tolerable limits and posed a carcinogenic risk, particularly for children. Consumption of two servings per week was found to reduce the health impact.

Summary: This study found the presence of SCCPs in sediments and fish from major rivers in Taiwan, indicating potential sources from human activities and accumulation in sediments. SCCP levels in sediments of 20 major rivers in Taiwan may pose potential ecological risks, but consumption of contaminated river fish showed minimal health risks for most residents, with some concern for health risks in children due to potential bioaccessibility of SCCPs. Routine monitoring of SCCPs in river ecosystems is recommended to protect aquatic organisms and human health.

Summary: This study compared the agreement between a food frequency questionnaire (FFQ) and a 7-day food diary (7DD) in assessing (poly)phenol intake and explored their associations with urinary and plasma (poly)phenol metabolites. The results showed that FFQ estimated a higher (poly)phenol intake compared to 7DD, and the agreement between the two assessment methods was moderate for major (poly)phenol classes but poor with biomarkers. Therefore, further research using biomarker approaches is needed to increase the accuracy of estimating (poly)phenol exposure in larger populations.
