Summary: Human populations are exposed to varying amounts of potentially toxic substances, with work-related or direct exposure usually resulting in greater toxin levels than environmental exposure. This study focused on detecting genotoxic damage caused by pollutants in individuals exposed to pesticide mixtures in Argentina through the analysis of cytogenetic markers. While this method allows for rapid detection of direct damage, it is limited in estimating the degree of exposure.

Summary: This study evaluates the impact of land use on the genetic and biochemical biomarkers of fish in streams of the Brazilian savanna. The results show that anthropic disturbance is associated with genotoxic damage and liver enzyme activity, but not with micronuclei frequency and gill enzymes.

Summary: Marine and ocean water pollution from plastic waste poses a serious threat to future generations, but data on the toxicity of plastic particles are currently incomplete due to their chemical diversity. Organisms have different risks from plastic particles depending on their habitat and feeding habits. We conducted experiments on feeding gastropod scraping mollusk Littorina brevicula with polymethylmethacrylate (PMMA) and polytetrafluoroethylene (PTFE) particles. Results showed that PMMA exposure caused oxidative stress and DNA damage in digestive gland cells, while no similar changes were observed in mollusks fed with PTFE-containing food.

Summary: This study investigated the detoxification mechanisms of red clover seedlings exposed to silver ions (Ag+) and found that the growth and physiological metabolism of the plants were disturbed. The research revealed that red clover seedlings initially transformed and immobilized Ag+ in the culture medium, and then transported and fixed them inside the cells, mainly in the form of unreduced Ag+ bound to biological molecules. Additionally, some Ag+ was reduced and formed crystalline silver nanoparticles. The results of this study provide valuable insights into the defense and tolerance mechanisms of red clover to Ag+ and the existing forms of Ag+ in vivo and in vitro.

Summary: Pollution of aquatic environments by industrial waste is a global recurring problem. Genotoxicity is an efficient and highly sensitive technique for detecting the presence of contaminants in the environment. A spill of vinasse in the Goiana River in Brazil caused significant environmental impact, leading to fish mortality and affecting the local fishing community. Biomonitoring using Aspistor luniscutis as a bioindicator revealed high levels of micronucleated cells and nuclear abnormalities, as well as tumorization in some specimens. The biomonitoring process plays a crucial role in assessing environmental impacts and preserving natural areas.

Summary: This study aimed to assess maternal offloading of metals in the Brazilian guitarfish through determining metal concentrations in pregnant females and offspring over two generations. The study found that the transfer efficiency of different metals varied, with some metals not detected in uterine content samples. The relationships between maternal length and concentration, as well as transfer capacity, were not significant, suggesting continuous exposure of females and potentially inefficient offloading of metals.

Summary: This study investigated the variation in biochemical response related to metal exposure among planktonic communities (micro and mesoplankton) in different locations and seasons from 2018-2020. The results showed that metals affected biomarkers in a non-linear pattern, indicating physiological stress related to metal contamination, especially in sectors contaminated by Fe, Mn, and Cd. The study highlights the complex relationship between metals, biochemical parameters, and seasonality in the marine planktonic community impacted by the Fundao dam rupture.

Summary: The disruption of the Funda & SIM;o dam resulted in the release of a large amount of mine tailings into the Doce River and eventually the ocean, posing challenges for the local biota. Analysis of shrimp samples from different sectors during dry and wet seasons showed seasonal and local effects on the bioaccumulation profile and biomarker response. The study suggests a higher bioavailability of metals during dry season, particularly for Cd, Cr, Cu, and Mn, and a higher Fe bioavailability in estuarine sectors during wet season. Native marine shrimp species proved to be effective indicators of sediment quality and sensitive to water contamination by metals. The findings highlight the importance of continuous monitoring in the estuarine region to understand the long-term effects of metal bioavailability, especially Fe, on the local biota.

Summary: Bees are declining worldwide, and pesticide use, including herbicides, has been found to negatively impact bees. Glyphosate (GLY) is the most sold pesticide and exposure to GLY can cause sublethal effects on bees. This study reviewed the literature on the sublethal effects of GLY and commercial formulations on bees. The findings showed that GLY exposure can alter gene expression, enzyme functioning, metabolism, tissue structure, microbiota diversity, learning, feeding, flight, circadian cycle, and body development in bees. Further research is needed to understand the long-term effects of GLY on bee colony homeostasis and the toxicity of surfactants in different commercial formulations.

Summary: The food industry has developed starch-poly (adipate co-terephthalate butyl) films with silver nanoparticles produced with Fusarium oxysporum components to control foodborne pathogens. These nanoparticles showed activity against different Salmonella serotypes, including multidrug-resistant strains. However, the migration of silver from the films to chicken meat exceeded the limits allowed by the European Food Safety Authority, indicating the need to improve the technique to prevent harmful concentrations.

Summary: This study monitored the concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) and procymidone (pesticides), as well as ochratoxin A (OTA) (mycotoxin) in different stages of winemaking process. The highest transfer of contaminants occurred during the crushing step for 2,4-D and the maceration step for OTA and procymidone. The winemaking process showed a 100% removal of contaminants, with different half-lives for each compound. The results highlight the importance of fermentation in reducing contaminants and the role of yeasts in detoxification.

The contaminated treatments showed decreased ethanol production and cell viability. After 168 hours of fermentation, the pesticides decreased by 22% and 65%, while OTA decreased by 52% and 58%. The decrease in procymidone and OTA was attributed to peroxidase activity and glutathione production in yeast cells.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
