“…Among them, almost 90% of sub-PAHs finally sink into the surface soil and sediment . It was previously reported that the contents of sub-PAHs were in the range of 0.523–1.69 and 0.354–9.19 mg kg –1 at suburban surface soils from Xi’an, China and residential soil from Australia, respectively, and some of them even exceeded the contents of ordinary PAHs . Although the most prevalent sub-PAHs may be different among various environmental matrices, nitro-PAHs (e.g., 9-nitroanthracene (9-NO 2 -Ant) and 1-nitropyrene (1-NO 2 -Pyr)) and methyl-PAHs (e.g., 9-methylanthracene (9-CH 3 -Ant)) were the most predominant sub-PAHs. , In addition, many studies reported that sub-PAHs such as 9-NO 2 -Ant, 1-NO 2 -Pyr, and 1-naphthol (1-OH-Nap) have stronger toxicities and mobility, as well as higher polarity, than their parent PAHs .…”

Substituted polycyclic aromatic hydrocarbons (sub-PAHs) are receiving increased attention due to their high toxicity and ubiquitous presence. However, the accumulation behaviors of sub-PAHs in crop roots remain unclear. In this study, the accumulation mechanism of sub-PAHs in crop roots was systematically disclosed by hydroponic experiments from the perspectives of utilization, uptake, and elimination. The obtained results showed an interesting phenomenon that despite not having the strongest hydrophobicity among the five sub-PAHs, nitro-PAHs (including 9-nitroanthracene and 1-nitropyrene) displayed the strongest accumulation potential in the roots of legume plants, including mung bean and soybean. The nitrogen-deficient experiments, inhibitor experiments, and transcriptomics analysis reveal that nitro-PAHs could be utilized by legumes as a nitrogen source, thus being significantly absorbed by active transport, which relies on amino acid transporters driven by H+-ATPase. Molecular docking simulation further demonstrates that the nitro group is a significant determinant of interaction with an amino acid transporter. Moreover, the depuration experiments indicate that the nitro-PAHs may enter the root cells, further slowing their elimination rates and enhancing the accumulation potential in legume roots. Our results shed light on a previously unappreciated mechanism for root accumulation of sub-PAHs, which may affect their biogeochemical processes in soils.

“…By constructing species interaction networks, researchers have investigated microbial communities in groundwater and soil contaminated with hydrocarbons. They have identified key species exhibiting distinct traits: an elevated affinity for carbon sources, an abundance of genes related to hydrocarbon degradation , and the ability to produce metabolites that nourish other microorganisms (Geng et al, 2022;Jia et al, 2023). Recently, cooccurrence network analyses using high-throughput metagenomic data have been developed to identify key species and syntrophic relationships in microbial consortia.…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

“…That DE principally binds with the nucleic acid at the exocyclic amino groups of adenine and guanine, transforming healthy cells into malignant ones. In the human health system, the major contaminating source is the inhalation of PAHs that mainly instigates the lung cancer risk (Flesher and Lehner, 2016;Geng et al, 2022). Apart from the carcinogenic potentiality, PAHs have the aptitude to affect the reproductive as well as the immune system of the human health via impeding with the thyroid glands hormone metabolizing enzymes and allergic skin reactions (IPCS 2010; Enuneku et al, 2021).…”

Degradation, detoxi cation or removal of the omnipresent polycyclic aromatic hydrocarbons (PAHs) from the ecosphere as well as their prevention from entering into food chain has never appeared simple. In this context, cost-effective, eco-friendly and sustainable solutions like microbes-mediated strategies have been adopted worldwide. With this connection, measures have been taken by multifarious modes of microbial remedial strategies, i.e., enzymatic degradation, bio lm and biosurfactant production, application of biochar immobilized microbes, lactic acid bacteria, rhizospheric-phyllospheric-endophytic microorganisms, genetically engineered microorganisms, and microbial fuel cell techniques etc. In this review, a nine-way directional approach which is based on the microbial resources reported over the last couple of decades has been described. Fungi found as the most dominant taxa among the CPAHdegrading microbial community constituting 52.2%, while bacteria, algae and yeasts occupied 37.4%, 9.1% and 1.3%, respectively. In addition to these, category-wise CPAH degrading e ciencies of each microbial taxa, consortium-based applications, CPAH-degradation related molecular tool, and factors affecting CPAH-degradation are the other important aspects of this review in light of their appropriate selection and application in the PAH-contaminated environment for better human-health management in order to achieve a sustainable ecosystem.
