Summary: This study utilized the comet assay to evaluate the genotoxic effects of picloram and dicamba on root meristems of Allium cepa. The results showed that both chemicals caused DNA damage in the onion roots at certain concentrations. Therefore, it is important to use appropriate concentrations of these chemicals in agriculture to protect the ecosystem and minimize threats to life.

Summary: This study assessed the cytogenotoxic effect of untreated and methyl orange treated on Allium cepa roots. It was found that roots exposed to treated dye solution had higher root growth, root length, and mitotic index, while roots exposed to untreated dye solution showed higher mitotic inhibition and chromosomal abnormalities. The research can be used as a biomarker to detect the genotoxic effects of textile dyes on biota.

Summary: The study found that PFOS has significant cytotoxic and genotoxic effects on Allium cepa root meristem cells. As the concentration increases, cell division decreases and chromosomal aberrations increase. This is the first study to investigate the cyto-genotoxic potential of PFOS in higher plants.

Summary: Numerous studies have shown the protective effects of 'FLASH' irradiation on normal tissues, reducing induced damage. Radical-radical recombination (RRR) and transient oxygen depletion (TOD) have been proposed as mechanisms for this effect. In this study, the authors aimed to evaluate the contribution of these mechanisms by assessing DNA crosslink formation and anoxic DNA damage following FLASH irradiation. The results showed no evidence of crosslink formation but supported the TOD mechanism through the observation of an anoxic profile of induced damage. The study also found that pretreatment with BSO reversed the reduced strand break damage mediated by FLASH.

Summary: In this study, single-walled carbon nanotubes (SWCNTs) synthesized by the thermal chemical vapor deposition (CVD) method were characterized using various techniques. The results showed that the obtained nanotubes were highly crystalline with an average diameter of 10.15 +/- 3 nm. Assessments of cytotoxicity and genotoxicity on Allium cepa root meristem cells exposed to SWCNTs revealed changes in mitotic phases, chromosomal aberrations, and DNA damage in a concentration-dependent manner. Molecular docking studies also demonstrated strong interactions between SWCNTs and DNA. This study highlights the cytotoxic and genotoxic effects of SWCNTs in A. cepa root meristematic cells, providing valuable insights into nanoparticle toxicology.

Summary: The comet assay is used to assess DNA damage in tissues and biological samples. This study found that storage time had varying effects on DNA damage levels in PBMCs and WB samples, with significant increases observed in WB samples stored for over 6 months. WB samples showed higher levels of DNA damage compared to PBMCs.

Summary: Zebrafish have become a popular model for assessing the genotoxicity of pollutants due to their orthologous genes and involvement in repair pathways. Comet assay is the main technique used in these studies, but standardization is needed for better interpretation and comparisons. Understanding repair mechanisms in zebrafish subjected to DNA damage is essential for further research on genotoxic effects caused by pollutants.

Summary: Pollution from mining activities can cause genotoxic damage to bats, particularly in species like Carollia perspicillata and Glossophaga soricina. High levels of elements such as Mn, Cr, Pb, and Zn were found in water samples from the mining area. The study suggests that bats in mining areas are susceptible to increased DNA damage, similar to what has been observed in other species.

Summary: Occupational exposure to pesticides in farmers results in significant DNA damage, showing a notable impact and variability in the studies. Smokers who are occupationally exposed to pesticides have slightly reduced DNA damage compared to non-smokers, indicating some genetic toxicity. The study demonstrates a higher risk of occupationally exposed rural workers developing related diseases due to the genotoxic effect of pesticides.

Summary: This study quantitatively and spatially evaluated the leachate plume from the Belo Horizonte landfill and found that the leachate contained significantly higher levels of tritium compared to rainfall. The tritium was transported towards the Coqueiros stream, with higher concentration close to the landfill slope. The study also identified factors that contribute to higher tritium levels in certain areas, such as the denser character of the leachate and the presence of rock near the surface.

Summary: The paper presents the results of a long-term experiment on fruit and berry crops grown in conditions of radioactive contamination. The study aims to understand how different species of trees and shrubs accumulate artificial radionuclides, focusing on their absorption through roots from soil. The findings show that the radionuclides are not evenly distributed among the plant organs, with leaves having higher concentrations than branches and fruits. The study also provides quantitative parameters for the transfer and distribution of specific radionuclides in different parts of the crops.

Summary: Public concerns about environmental protection have increased since the Fukushima accident. The soil-plant transfer factor (Fv) is an important parameter for environmental risk assessment. The study investigates the behavior of 90Sr in Brazilian soils and finds that a significant portion of 90Sr remains potentially mobile, mainly in the bioavailable phase. The behavior of 90Sr in these soils is influenced by ionic competition mechanisms and the presence of stable Sr and major nutrients. The mineralogy of the soils also plays a role in the transfer of 90Sr.

Summary: Activity concentrations of 90Sr in fish in lakes within the Chornobyl Exclusion Zone exceed permissible levels, and transferring contaminated fish to clean water does not effectively reduce 90Sr content. Establishing permissible levels of 90Sr concentration only in fish fillet is appropriate for human radiation protection.
