Summary: The study showed that EDTA significantly enhances the translocation of Pb from roots to leaves in Bidens pilosa L., with a translocation factor of up to 2.43. EDTA was found to decrease Pb retention in specific root zones and increase the water-soluble Pb fraction in plant cells, thereby enhancing Pb translocation in plant vascular bundles.

Summary: The study demonstrates the strong metal absorption and tolerance of Iris sibirica, especially under 500 mg/L of metal stress, the plant shows the highest absorption of Ni, Co, and Pb. This suggests that Iris sibirica is more suitable for phytoremediation of Pb-contaminated mine wastelands compared to Ni and Co.

Summary: Despite the implementation of environmentally compatible integrated control strategies, such as mating disruption and attract-kill strategies, the management of codling moth still heavily relies on insecticides. There have been varying levels of insecticide resistance towards different types of insecticides in codling moth populations worldwide, involving both metabolic and target-site mechanisms.

Summary: This study discusses the germination and physio-biochemical effects of lead (Pb) stress on alfalfa in the context of Inner Mongolia's lead ore. It is found that low concentrations of Pb stress can improve the resistance of alfalfa seeds, while high concentrations are not tolerable. Results show that a Pb concentration of 5 mg/L promotes seed germination and increases chlorophyll content. However, as Pb content and stress increase, levels of malondialdehyde (MDA), H2O2, and catalase (CAT) increase, while root cell viability, chlorophyll, and soluble protein content decrease. The findings suggest that alfalfa is tolerant to Pb stress at a concentration of 5 mg/L but inhibited at higher levels and poisoned at 500 mg/L. Principal component analysis (PCA) highlights the physiological changes and tolerance of alfalfa under Pb stress, specifically in relation to H2O2, O-2(-), total chlorophyll, chlorophyll a, CAT, and proline content.

Summary: The electrochemical behavior of Pr(III) ions in molten NaCl-2CsCl solutions was studied using different electrochemical techniques. The reduction process on inert electrodes occurs in one stage and is reversible at low scan rates. The diffusion coefficients of PrCl63- complex ions were determined at different temperatures, and the co-reduction of Pr(III), Ga(III), and Pb(II) ions was investigated. The electrodeposition of Pr(III) ions on reactive electrodes was also studied, and Praseodymium was successfully extracted from the molten salt using potentiostatic electrolysis.

Summary: Phytoremediation is an effective in-situ remediation technology that utilizes the ability of plants to remove pollutants from soil. This study investigated phytoremediation for Pb removal from contaminated soil in Spain. The results showed that energy recovery from biomass was more environmentally friendly compared to direct landfill disposal.

Summary: Lead (Pb) is one of the most toxic elements on earth, mainly originating from automobiles, paint and electroplating industries. Plant growth and biomass are severely affected by Pb-induced stress. The combined application of citric acid (CA) and glutathione (GSH) can promote the phytoremediation of Pb and help plants combat Pb toxicity.

Summary: This study investigates the effects of different chelates on the uptake of heavy metals in contaminated soils. The results show that sequential addition of chelates significantly increases the uptake of certain heavy metals by ryegrass, but also reduces plant biomass.

Summary: In this paper, an all-composite L-joint was proposed and subjected to a bending test. The primary failure mode of the L-joint was found to be the crack of the stiffener outer skin, dominated by fiber compressive failure. The optimized structure showed improvement in load-bearing capacity and stiffness.

Summary: Due to the rapid development of industry and agriculture, heavy metal pollution in saline soil has become increasingly severe. Halophytes such as Kochia scoparia have the ability to survive at high salt and heavy metal concentrations, making them suitable candidates for phytoremediation of heavy metals in saline soils. In this study, K. scoparia seedlings were exposed to different doses of Cd and NaCl to explore their tolerance and phytoremediation ability. The results showed that Cd had no significant toxic effect on K. scoparia seedlings, while NaCl reduced the biomass of K. scoparia without showing any visible toxic symptom. Cd accumulation in K. scoparia was mainly distributed in the shoot, and the accumulation of Cd in the shoots was significantly higher than that in the roots, especially under low-Cd treatment. Moreover, the contents of glutathione and oxalate in plants increased gradually with the increase of NaCl concentration.

Summary: This study aimed to investigate the combined ecotoxicological effects of Cd, Pb, Zn, Hg and regulation mechanisms in Solanum nigrum L. The co-exposure of these heavy metals hindered the transformation of Cd, Zn, and Hg into non-available forms. Each metal individually induced oxidative damage to S. nigrum L., but their combination further enhanced ecological toxicity. Internal regulation, such as hyperaccumulation of Cd in plant roots and immobilization in the cell wall and vacuole, and external regulation involving changes in soil microbial communities, played important roles in detoxification pathways.
