Summary: The purpose of the study was to investigate the risk of consuming vegetables exposed to toxic air pollutants, especially PAHs. The study found comparable PAH concentrations in some of the sampled villages to relatively polluted regions in the world, with biomass burning and fossil fuel usage identified as the major sources of PAHs in rural environments. The study highlighted the importance of analyzing individual pollution sources.

Summary: The fertility of soils contaminated by waste motor oil (WMO) can be restored through efficient and safe bioremediation techniques. This study aimed to biostimulate WMO-impacted soil with crude fungal extract (CFE) and green manure (GM) of Cicer arietinum, and to use Sorghum vulgare, Rhizophagus irregularis, and/or Rhizobium etli for phytoremediation. Results showed that after biostimulation with CFE and GM, the WMO concentration in the soil decreased from 34,500 to 2066 ppm after 60 days. Subsequent phytoremediation with S. vulgare and R. irregularis reduced the WMO concentration to 86.9 ppm after 120 days, ensuring the restoration of soil fertility for safe agricultural production.

Summary: This study reveals the critical role of a JA-responsive glutathione S-transferase gene (SlGSTU24) in alleviating cold stress in tomato. SlGSTU24 is expressed in all tissues and is responsive to both JA and cold stress. Upregulation of SlGSTU24 attenuates cold-induced oxidative stress, while its expression is dependent on the crucial regulator of JA signaling pathway, SlMYC2. These findings uncover a crucial module MYC2-SlGSTU24 that maintains ROS homeostasis in tomato under cold conditions.

Summary: In this study, a tau-like glutathione transferase family gene named GmGSTU23 was identified in soybean, which showed a concentration-time-specific expression pattern in response to salt stress. Transgenic lines with GmGSTU23 displayed enhanced salt tolerance, root length, and fresh weight compared to the wild type. Changes in glutathione pools and associated enzyme activity were observed, indicating that GmGSTU23 enhances the activity of glutathione transferase to scavenge reactive oxygen species and glutathione, thereby conferring enhanced tolerance to salt stress in plants.

Summary: Mycoremediation with halophilic Aspergillus sydowii showed significant removal of PAHs in a hypersaline environment, mainly through biotransformation. Transcriptomic analysis revealed that A. sydowii grown in hypersaline conditions upregulated numerous genes related to PAHs metabolism, while the activity of traditional enzymes like lignin modifying enzymes remained unchanged. The significant upregulation of the chloroperoxidase gene may be associated with fungal detoxification processes.

Summary: Insects fed on cassava leaves showed the highest induction of GST, followed by those fed on bitter leaf. Allelochemicals in food plants may have compensatory toxicity-alleviating actions on one another. The catalytic properties of GST induced by different diets vary, and hindgut seems to be the primary organ of detoxication.

Summary: This study investigated the contamination of sediments by polycyclic aromatic hydrocarbons (PAH) and the response of oxidative stress biomarkers (glutathione-S-transferase activity-GST and lipoperoxidation-LPO) in the polychaetes Namalycastis abiuma along the urbanized margin of the Guajara Estuary, Brazilian Amazon coast. The results showed higher PAH concentrations during the dry season, with high molecular weight PAHs originating from fossil fuel burning. Although the ecotoxicological PAH risks were low, the toxicity equivalency was higher near the oil terminal. The study also found that the rainy season coincided with higher GST activities at the oil terminal and industrial sites, indicating increased PAH bioavailability and prolonged exposure to toxicants. LPO levels were similar in both seasons, suggesting sufficient enzymatic activities to handle prooxidant exposure. The findings suggest that the estuarine condition exerts subtle oxidative stress on a keystone species, and special surveillance is needed for the deposition margins within the mangrove areas and port operation.

Summary: Studies on anurans have been conducted for over 40 years to evaluate the adverse effects of benzo(alpha)pyrene (B alpha P), showing genotoxic, hepatotoxic, and immunotoxic effects. This study aimed to assess whether the route of administration of B alpha P influences its effects on hepatic biomarkers, with morphological biomarkers being more significantly affected than biochemical ones. The exposure pathway and time both modulate the effects of B alpha P on hepatic biomarkers in anurans.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
