Summary: The study found that drought tolerant hybrids had higher levels of proline, superoxide dismutase enzyme, and glycine betaine. While plants under drought stress generally exhibit low nitrate reductase activity, the drought tolerant hybrids actually had higher NR activity compared to the susceptible hybrids. The control plants kept under fully irrigated conditions showed the highest amount of NR.

Summary: This study examines the interactions between mercury (Hg) and microplastics (MPs) and the mobilization of Hg from MPs into organisms. The results suggest that MPs can adsorb and retain Hg(II) under environmentally relevant conditions but desorb a significant amount in simulated avian digestion fluid. This indicates that birds that ingest MPs may have increased exposure to Hg(II).

Summary: Salinity is a global problem caused by irrigation with salty water, excessive fertilization, or poor leaching capacity in soils. Biostimulants, like corn steep liquor (CSL), can enhance salt tolerance in plants by reducing the uptake and accumulation of toxic ions. This study found that CSL application improved photosynthetic efficiency and reduced the generation of reactive oxygen species, resulting in reduced phytotoxicity and increased growth of pepper plants under saline conditions.

Summary: The behavior of microplastics as carriers of environmental contaminants can change the fate and transport of toxic substances in aquatic systems. Factors such as pH, humic acid, and particle size play a crucial role in the adsorption of metal ions on microplastics. In a simulated gastrointestinal environment, the desorption rates of metal ions from microplastics are high, suggesting a potential toxicological risk after ingestion of metal-contaminated microplastics.

Summary: The addition of surfactants improved the adsorption capacity of microplastics for lead ions, with SDBS significantly enhancing the adsorption compared to TX100 and HDPB. The adsorption efficiency of microplastics for Pb2+ initially increased and then decreased with increasing adsorption time and Pb2+ concentration. The pH of the solution had a significant influence on the adsorption of Pb2+ by microplastics.

Summary: This article reports a novel porous phosphomolybdate-based poly(ionic liquid) catalyst with 70% water (PDIM-PMo-W70%). The catalyst showed a turnover frequency (TOF) value of 41.15 h-1 for dibenzothiophene (DBT) removal, which was 35.47 and 9.92 times higher than that of HPMo and PDIM-PMo, respectively. The effects of water content, reaction temperature, H2O2/S molar ratio, catalyst dosage, and different sulfur-containing compounds on the oxidative desulfurization (ODS) performance were investigated in detail.
