Summary: The study evaluated the toxic effects of heavy metals on the plant Robinsonecio gerberifolius exposed in different sites in Mexico City, showing an increase in genotoxicity and induction of oxidative stress. The presence of toxic HM in the atmosphere of Mexico City and its metropolitan area was confirmed through the analysis of alpha- and ss-carotenoids and miR398 levels in the exposed plants.

Summary: Heavy metal pollution has harmful consequences on soil fertility, and earthworms are used as test organisms to evaluate the ecotoxicity of polluted soils. This study exposed Eisenia andrei to polymetallic contaminated soils for 7 and 14 days in southeastern Tunisia. The results showed increased heavy metal accumulation, genotoxicity, and cytotoxicity in earthworms after 14 days of exposure, as well as changes in biochemical and transcriptional responses. These findings support the use of earthworms as bioindicator species for pollution monitoring and provide valuable information about the harmful impact of biota exposure to contaminated soils.

Summary: In this study, various parameters of oxidative stress, immune response, and abnormalities in the erythrocyte nucleus of Labeo rohita inhabiting the polluted Kshipra River, India, were measured. The heavy metal concentrations in the river water were in the order of Ni > Fe > Cd > Cr > Mn > Zn > Cu. The fish showed increased levels of antioxidant enzymes in gills, liver, and gut compared to the reference fish, but decreased levels of GST and GSH. Heavy metals also caused immunosuppression and histopathological changes in the fish. These findings highlight the potential impact of heavy metal-induced stress on fish inhabiting polluted river water and the importance of pollution control.

Summary: The genotoxic effects and underlying mechanisms of titanium dioxide nanoparticles (TiO2 NPs) on human bronchial epithelial cells (BEAS-2B) were investigated in this study. TiO2 NPs were found to induce cytotoxicity, oxidative stress, and DNA oxidative damage, with DNA oxidative damage being a more sensitive indicator for detecting the genotoxicity of TiO2 NPs.

Summary: Chromium occurs in different oxidation states, with hexavalent forms being more toxic and primarily resulting from human activities. A hydroponic experiment was conducted to compare the remediation abilities of Marsilea minuta and Pistia stratiotes towards chromium. Both plants accumulated the highest amounts of chromium at a concentration of 1.5 mM. Increasing concentrations of chromium led to decreased plant dry weights and increased levels of malondialdehyde (MDA). The results suggest that both macrophytes are suitable for chromium phytoremediation, and the antioxidant enzyme activity is vital for understanding plant physiology under metal stress.

Summary: The oxidative stress on terrestrial animals caused by heavy metal-contaminated soil was evaluated using oxidative potential (OP), which was found to be influenced mostly by water extractable Cu, Pb, Zn, and Cd in the soil. The study also showed that oxidative stress in earthworms can be reflected through biomarkers and is negatively correlated with the OP of soils. Metabolomic analysis further confirmed the correlation between four ROS-related metabolites in earthworms and OP values, suggesting that OP can serve as an indicator for ecological risk assessment of heavy metal-contaminated soil.

Summary: The study demonstrated that different fractions of Absinth Tablet (AT) do not exhibit cytotoxic effects in HepG2 cells, show hepatoprotective activities, and exhibit antigenotoxic activity against H2O2-induced DNA damage. The results suggest that AT may be useful in preventing and treating oxidative stress-induced hepatic problems.

Summary: This study investigated the toxicity effects of bismuth (Bi) on garden cress plants. The results showed that low concentrations of Bi had no significant effects, but higher concentrations caused toxicity in terms of germination index and root length reduction. Bi exposure also induced genotoxicity and metal accumulation in the plants.

Summary: This study investigates the early response of cancer cells to gamma radiation and oxidative stress, and explores the protective mechanisms offered by natural extracts from the resurrection plant Haberlea rhodopensis. The findings suggest that these extracts can effectively modulate the cellular response to genotoxic and oxidative stress, reducing their severity.

Summary: Azoxystrobin is a widely used systemic fungicide that inhibits mitochondrial respiration in target fungi, but its effects on non-target organisms are not well studied. This research evaluated biomarkers of oxidative stress, hematological, physiological, and genotoxicity in cichlid fish exposed to environmentally relevant concentrations of AZX, showing negative effects at realistic concentrations and highlighting the importance of considering developmental stage on biomarker evaluation.
