“…It should be noted that China, the United States, and India have focused on the accumulation of heavy metals by aquatic plants in aquatic matrices [57][58][59]. The potential to remove mercury from sediments was established by research on the aquatic plants Carex heterostachya, C. brevicuspis, A. selengensis, Polygonum hydropiper, and G. longituba [60]. According to Ulaganathan, E. crassipes, A. cristata, and S. natans are three more prospective candidate aquatic species for phytoremediation of hazardous metals such as Pb, As, Hg, Cd, and Ni [59].…”

Mercury is classified as one of the world’s most toxic and dangerous pollutants. It tends to bio-accumulate and biomagnify within the trophic chain and is persistent. Various approaches are available to remediate Hg-affected sites, including phytoremediation, which includes the use of plants to clean up contaminated environments. Phytoremediation of mercury contamination is at-tracting increasing attention because of its advantages: it is environmentally friendly, inexpensive, simple, and can improve soil fertility. In this report, VOSviewer, and Bibliometrix software were used to analyze 457 and 697 documents published from 2000 to 2023, retrieved from the data-bases WoS and Scopus, respectively. China, India, the United States, and Spain are the top four most productive countries. The largest topic area was environmental sciences, and the Chinese Academy of Sciences was the organization that contributed the most to the overall number of pub-lications. The keywords with the highest frequency, excluding phytoremediation and mercury in WoS, were heavy metals, accumulation, cadmium, soils, and phytoextraction. In Scopus, the most frequent keywords were bioremediation, heavy metals, soil pollution, bioaccumulation, biodeg-radation, and environmental. From the above analysis, we concluded that future research should focus on 1) finding native plants, 2) increasing remediation ability through assisted phytoremedi-ation, 3) studies of molecular mechanisms in plants with phytoremediation potential, and 4) ge-netic engineering applications. This study provides insight into trending themes and serves as a reference for future research.

“…In recent decades, with the widespread use of antibiotics in various elds such as healthcare, industry, and agriculture, there has been a signi cant increase in antibiotic resistant bacteria and antibiotic resistance genes (ARGs) in the environment (Rodriguez-Mozazs S et al, 2015; Peng D et al, 2023). As novel environmental pollutants, ARGs (Antimicrobial Resistance Genes) can be integrated into various microorganisms through mobile genetic elements, thereby forming a transmission system that spans "human-environment-human" (Zarei-Baygi A et al, 2019; Cao F et al, 2021).…”

Antimicrobial resistance genes (ARGs) are widespread across various regions. While several studies have investigated the distribution of antibiotic resistance in natural environments, the occurrence and diversity of ARGs in the Three Gorges Reservoir have not been fully elucidated. In this study, we employed metagenomic sequencing techniques to investigate the abundance, diversity, and influencing factors of ARGs in the ecosystem of the Three Gorges Reservoir. A total of 874 ARGs, 20 antibiotic classes against which resistance genes are deployed, and 6 resistance mechanisms were detected. The dominant ARG is the macB gene, the dominant antibiotic class is multidrug resistance (MDR), and the dominant resistance mechanism is antibiotic efflux. The microorganisms with the highest contribution to ARGs are Betaproteobacteria and Gammaproteobacteria, while physicochemical factors have little impact on the distribution of ARGs. The results indicate that the Three Gorges Reservoir constitutes a significant reservoir of ARGs. By examining the distribution of ARGs in the sediments of the Three Gorges Reservoir and the associated characteristics between microorganisms and ARGs, we aim to understand the current state of resistance pollution in the Three Gorges region, thereby providing theoretical support for risk assessment of resistance genes in the environment.

“…According to ASTDR, 2015 (Agency for Toxic Substances and Disease Registry), mercury ranks 3 rd in the list of priority dangerous substances. Because it is used in numerous industrial processes, mercury is released in large quantities in different environmental compartments, such as soil, surface water, wastes, atmospheric particles [4][5][6][7][8][9][10]. In addition, due to the chloroalkane industry, significant mercury pollution of water, air and fish was found in Russia (Chlor-alkali plant JSC "Kaustic" Volgograd, Chlor-alkali plant Usoliekhimprom), Czech Republic (Chlor-alkali plant Spolana Neratovice) [11].…”

The aim of the study was to develop a new method for mercury determination from plants grown on mercury-polluted soils as well as to evaluate the mobility and bioavailability of mercury in the soil and its transfer to different plant organs (root, stem, leaves) from three different plants, such as mustard (Sinapis alba), thyme (Thymus serpyllum) and wild thyme. A cold vapor atomic absorption spectrometry (CV-AAS) method for the detection of mercury in plants was developed. The developed method was validated in the laboratory and was verified using two different certified reference materials (CRMs) type matrices, namely: NIST 1515 Apple Leaves and BCR-482 Lichen.
