Summary: This study investigated the effects of rhamnolipid (RL), nano zero-valent iron (nZVI), and anthraquinone-2,6-disulfonic acid (AQDS) on the degradation of polycyclic aromatic hydrocarbons (PAHs) in soil. The results showed that the treatment of 5 mg& BULL;kg?1 RL + 1% nZVI + 0.2 mmol& BULL;kg?1 AQDS had the highest degradation rate. High-throughput sequencing analysis revealed the dominant microbial species involved in anaerobic and aerobic degradation of PAHs. The activities of methyltransferase, dehydrogenase, and catechol 1,2-dioxygenase were consistent with the degradation process of PAHs.

Summary: Based on 10 years of environmental monitoring, the study examined the regularities of heavy metals and polycyclic aromatic hydrocarbons (PAHs) in agricultural landscapes and their accumulation in Triticum aestivum. The prevailing wind direction and atmospheric transfer were found to be significant factors for pollutants accumulation. As the content of pollutants in soil increased, their accumulation in Triticum aestivum exceeded maximum permissible concentrations (MPC), particularly for Pb, Cd, and BaP. The influx of pollutants into the plant was only significant for Mn, Cr, and BaP, while others were mainly accumulated through foliar influx. Triticum aestivum showed higher tolerance to heavy metals pollution compared to PAHs.

Summary: Chelating agents are used to improve the uptake of heavy metals by plants and increase phytoextraction efficiency. Compound activators, such as a fruit peel-based activator (OG), have been widely applied in recent years. This study investigated the effects of OG combined with phosphate-solubilizing bacteria (AP) on the phytoextraction of Cd from farmland soil by ryegrass. The results showed that the optimal combination of OG and AP improved the growth of ryegrass and enhanced the phytoextraction of Cd. Total soil nitrogen and pH were found to have the greatest influence on phytoextraction. The findings suggest that the application of the fruit peel-based activator and phosphate-solubilizing bacteria can effectively enhance phytoextraction of Cd from contaminated soils.

Summary: The sources of microplastics and nanoplastics are widespread and include everyday activities. However, the limited techniques for characterization hinder the determination of their sources. We propose advancing Raman imaging by combining it with various algorithms to improve signal-noise ratio and imaging certainty, enabling the characterization of microplastics. We can capture and identify microplastics carried by smartphones, which are released from clothing and plastic decoration trinkets, accumulating on the phone surface or in ports. Further methodological improvements are necessary due to the complexity of the samples.

Summary: Earthworms are being studied for their potential in bioremediation due to their impact on pollutant fate. Different earthworm species have varying sensitivities and capacities to break down contaminants, and Lumbricus terrestris is the most suitable species for bioremediation of OP-contaminated soil due to its higher levels of detoxification enzymes and oxidative homeostasis mechanisms compared to Eisenia fetida andAporrectodea caliginosa. These findings suggest L. terrestris as a better candidate for soil bioremediation than epigeic earthworms.
