Summary: This study used the CBMN assay to determine the genotoxic and cytotoxic effects of microplastic on human peripheral lymphocytes, revealing both genomic instability and lack of cytotoxic potential in larger microplastic particles. Further investigation on smaller plastics and chronic effects on human population is recommended.

Summary: The goal of this study was to review the scientific literature on fluoride exposure's genotoxic effects. The databases used were PubMed/Medline, SCOPUS and Web of Science. Quality of the included studies was assessed using EPHPP. Out of the twenty studies reviewed, only a few indicated genotoxicity from fluoride exposure. Majority of the studies showed negative results. Based on EPHPP, one study was classified as weak, ten as moderate, and nine as strong. Overall, it has been established that the genotoxicity of fluoride is limited.

Summary: The objective of this study was to investigate the micronucleus frequency in buccal mucosa of gasoline station workers. The results indicated that exposure to gasoline could increase the frequency of micronucleus, and cigarette and alcohol consumption, along with working in gasoline stations, increased the abundance of micronucleus.

Summary: Agricultural expansion leads to habitat loss and exposure to pesticides for non-human primates. This study analyzes the presence of pesticides in river water in the habitat range of wild chimpanzees in Uganda and investigates the relationship between pesticide exposure and oxidative damage. The results show that chimpanzees from high exposure areas have higher levels of oxidative DNA damage, and individuals with higher C-peptide levels also have higher oxidative DNA damage and lipid peroxides.

Summary: The study revealed that exposure to 50 and 60 Hz magnetic fields may lead to a slight increase in expression of ROS-related genes, but had no significant effects on cytosolic O-2(center dot-) levels, DNA damage, and repair rate. Additionally, exposure to magnetic fields did not exceed the expected rate of false positive findings for changes in the expression of DNA damage-signaling genes.

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: This study evaluated the genotoxicity of eight nitrosamines using metabolically competent human HepaRG cells. The HepaRG spheroids, which had higher levels of cytochrome P450 activity compared to monolayer cells, were used along with conventional 2D cultures. The results suggest that HepaRG spheroids may provide a sensitive, human-based cell system for evaluating the genotoxicity of nitrosamines.

Summary: The potential genotoxic effects of engineered nanomaterials (ENMs) on DNA repair pathways have been investigated using a fluorescence multiplex-host-cell reactivation (FM-HCR) assay. Results showed that some ENMs may enhance DNA repair capacity while others suppress it. This method can be a valuable part of a multitier, in vitro hazard assessment of ENMs, providing insights into the interplay between ENM properties, DNA repair efficiency, and genomic stability.

Summary: The study evaluated the protective effects of chrysin against carboplatin-induced DNA damage, showing that chrysin significantly decreased the level of DNA damage, likely due to its potent antioxidant properties. This suggests that chrysin could be developed as a chemoprotective agent against chemotherapy associated side-effects.

Summary: The nuclear envelope regulates transport in and out of the nucleus and is essential for nuclear functions. During mitosis, the nuclear envelope disintegrates and reforms, but it is delayed on lagging chromosomes and DNA bridges. Defects in the coordination between nuclear envelope reformation and chromosome segregation impair nuclear functions and result in DNA damage.

Summary: This study focuses on finding environmentally friendly alternatives to synthetic dyes and using liquid CO2 as a waterless medium for applying colorants to textiles. The research reveals that a biocolorant produced by Cortinarius sanguineus fungus is suitable for dyeing PET fibers in supercritical CO2. Toxicological evaluations show that the colorant has low toxicity and is non-mutagenic, making it a potential synthetic dye alternative.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: An Endocrine Disrupting Chemical (EDC) is a compound that disrupts the function of the endocrine system and is found in the environment. EDCs, such as Bisphenol A and pesticides, have been shown to have negative effects on the female reproductive system. Understanding the relationship between EDCs and women's health is crucial for developing strategies to protect reproductive health and informing public policy decisions.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: Air pollution is associated with a range of health issues and gestational exposure to environmental pollutants may be linked to neurodevelopmental disorders. This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.

Summary: Heteroatom doping can reconfigure the electronic structure of heterogeneous catalysts, leading to the development of advanced oxidation water purification materials with superior performance and stability. In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.

Summary: This study investigated the bacterial degradation of naphthalene (NPT) isolated from crude oil-contaminated soil. Bacillus sp. GN 3.4, a potential bacteria for NPT biodegradation, was isolated and the optimal conditions for NPT degradation were determined. The study suggests that Bacillus sp. GN 3.4 could potentially aid in bioremediation by eliminating NPT from the soil.
