Summary: The effects of micro polyethylene (mPE) and micro polypropylene (mPP) on soil-wheat systems were studied in this research. Results revealed that with increasing levels of mPE/mPP, the chlorophyll concentrations in wheat leaves decreased significantly in different Cd pollution levels soils (0, 1, and 5 mg kg-1). The addition of mPE improved aboveground and root biomass, while the addition of mPP increased aboveground biomass at low content but decreased it at high content. The mixed contamination of mPE/mPP and Cd influenced Cd enrichment, with a promotion effect in the aboveground biomass and a promotion effect in the roots at higher Cd concentrations.

Summary: Heavy metal pollution in soil can have detrimental effects on soil ecosystems and human health. This study examined the reduction of bioavailable fractions of As and Pb in paddy soil using artificial lightweight material (ALM) made from recycled materials. Results showed that the combination of ALM with FeO and lime led to the highest reductions in bioavailable fractions of As (52.8%) and Pb (65.7%) in soil. The mobility and bioavailability of As and Pb were mainly controlled by soil pH, electrical conductivity, P2O5, and soil organic matter. Long-term monitoring is necessary to assess the longevity of soil amendments.

Summary: The aim of this study was to investigate the residual effects of nickel (Ni) in soil on the growth and yield of cowpea. The results showed that the application of 10 mg Ni kg(-1) in the previous crop along with 10 mg kg(-1) of zinc (Zn) in the current experiment resulted in the highest plant height, number of branches, number of pods, stover yield, and seed yield of cowpea. The concentration of iron (Fe), manganese (Mn), and zinc (Zn) in the grain and stover increased significantly up to 10 mg kg(-1) of residual Ni, but decreased beyond this level. The urease activity and available nitrogen content in the soil after harvest also increased with the increase in residual Ni content.

Summary: Butyl Xanthate (BX) and nickel (Ni) combined pollution had significant impacts on freshwater algae (Chlorella pyrenoidosa), with the Ni/BX mixture showing the strongest inhibition effect. Chlorella pyrenoidosa exhibited sensitivity to these pollutants, possibly due to damage to cell structures caused by the pollutants. Furthermore, the pollutants induced oxidative stress in Chlorella pyrenoidosa, leading to lipid oxidation.

Summary: An incubation experiment was conducted to investigate the impacts of urease inhibitors on soil urease activities and microbial gene abundances. The results showed that urease inhibitors decreased extracellular urease activity while increasing intracellular urease activity of soil. They also significantly increased bacterial and fungal gene abundances but had no significant effect on archaea gene abundance. Bacterial gene abundances were closely related to intracellular urease, suggesting that bacteria played a more important role in this process than fungi and archaea.

Summary: The paper proposes a simple one-stage synthesis method for organic-inorganic composite materials based on iron (III) and cobalt (II) oxide compounds. The process of forming cobalt (II) ferrite (CoFe2O4) structure on the surface of biochar was studied. Composite materials cobalt ferrite/biochar were obtained for the first time using agricultural waste. The results suggest that biochar composites based on CoFe2O4 have great potential for practical industrial wastewater treatment.

Summary: This study developed a simple method for synthesizing fluorescent nanoparticles from fruit peels. Carbon dots (CDs) were fabricated from Annona squamosa (L.) peels using a carbonization technique. The synthesized CDs were confirmed to be fluorescent and capable of being absorbed by germinating mung bean seeds, indicating their potential use as a bioimaging agent. This novel method of synthesizing CDs was found to be eco-friendly, rapid, and cost-effective.

Summary: Benzo[a]pyrene (BaP) was found to cause dose-dependent toxic effects on Solanum lycopersicum L., leading to reduced biomass and accumulation of BaP in the plant tissues. Physiological and biochemical indices were severely damaged, and histochemical analysis showed the formation of formazan spots in the leaves. The structure of the roots and leaves of S. lycopersicum also changed depending on the BaP dose.

Summary: Climate change and land degradation result in carbon loss. Agroforestry is suggested as a potential method to mitigate climate change. The Indian government promotes tree-based systems to increase tree cover and mitigate climate change. Poplar and eucalyptus are major agroforestry tree species with high carbon sequestration potential. Successful commercial agroforestry systems have been implemented in the Indo-Gangetic plains.

Summary: This study investigated the use of copper oxide nanoparticles (CuO NPs) as seed primers to enhance the growth of Brassica juncea. The results showed that seed priming with 4 mg/L CuO NPs for 30 minutes significantly increased the growth indices and biochemical parameters of B. juncea. Antioxidant enzyme activity and biochemical parameters were also enhanced. This suggests that CuO NPs can effectively improve the performance of B. juncea and may have potential in other crop species.

Summary: The population growth leads to increased demand for plant-based food products, but biotic and abiotic stresses can reduce crop yields and worsen the food crisis. Protecting plants with phytohormones, particularly salicylic acid (SA), can help enhance plant resistance to stresses. However, high doses of SA can inhibit plant growth. Developing delivery and controlled release systems for SA is necessary to maintain optimal concentrations. This review discusses various types of nanoparticles as carriers for SA, their impacts on plants, and the mechanisms of controlled release, providing valuable insights for the design of effective SA delivery systems.

Summary: This article analyzes the impact of anthropogenically transformed environment on the content of pharmaceutically valuable biologically active compounds in medicinal plants. The study focuses on phenolic compounds such as flavonoids, anthocyanins, tannins, and phenolic acids. The discharge of transmissible forms of heavy metals, including cadmium, lead, and mercury, from factories has led to contamination of soil. This affects the activity of enzymes involved in the biosynthesis of phenolic compounds in medicinal plants, resulting in changes in their quantity.

Summary: Traditional freshwater sources have been over-abstracted, resulting in a worldwide water scarcity crisis. An investigation found that industrial wastewater samples contained high concentrations of Zn2+ and Pb2+, which are known to be highly harmful to humans and wildlife. This study used Streptomyces sp. as a biosorbent to effectively extract Zn2+ and Pb2+ from single and binary metal aqueous solutions. The biosorbent demonstrated high adsorption capacity and followed Freundlich isotherm, making it a potential alternative for removing Zn2+ and Pb2+ from aqueous solutions.
