Summary: The study focused on the occurrence, composition profile, and spatial distribution of PAHs and OPAHs in surface sediment samples collected from the Taiwan Strait. The results indicated the presence of various PAHs and OPAHs, with higher concentrations observed at sampling sites adjacent to the mainland and in the northwest part of the Taiwan Strait. The study suggested important continental input and particle sedimentation as contributing factors to the distribution of PAHs and OPAHs in the region, with limited ecological impact based on sediment quality guidelines.

Summary: Biodegradation is a sustainable and cost-effective solution for groundwater pollution. In this study, the microbial populations involved in the biodegradation of poly-contaminants in a heavily contaminated groundwater pipeline were investigated. The microbial communities were analyzed using genome-resolved metagenomic analysis, revealing the changing microbial communities in a highly effective groundwater treatment system.

Summary: The study found that in IWS-enhanced CWs with and without Phragmites australis, the sulfate removal rate was higher compared to controls. Microbial analysis showed that the abundance of sulfate-reducing bacteria, sulfur oxidizing bacteria, and carbon-degrading bacteria improved sulfate removal efficiency. Co-occurrence network analysis revealed interactions between different bacteria, including competition and cooperation to enhance nutrient removal processes.

Summary: The Mediterranean Sea is under high anthropogenic pressure, leading to the discharge of persistent organic pollutants from intensive industrial activities. These compounds can easily contaminate the entire marine ecosystem through water, sediment, and biota. The study found that both seasonal and human factors strongly influence the transfer of contaminants, with PAH and PCB contamination being more significant during the summer. Low molecular weight PAHs were mainly detected in the target matrices, while only a few congeners of PCBs were found. The bioaccumulation process in zooplankton was influenced by both living and feeding habits.

Summary: Quantitatively linking the composition and function of microbial communities is challenging. Inspired by genetics, an ecological community-function landscape could be defined to map community composition and function. Exploiting the parallels between both landscapes could improve our ability to engineer and optimize microbial consortia.

Summary: The study found that the concentration of polycyclic aromatic hydrocarbons (PAHs) in sediments around the HMS Royal Oak shipwreck was low and below the effects-range low (ERL) for the OSPAR maritime area, indicating that the sediments are not currently being impacted by petrogenic hydrocarbons and show no long-term impact by previous oil-spills. Additionally, analysis of sediment microbiomes showed no significant differences in bacterial community structure with distance from the shipwreck, with very low levels of obligate hydrocarbonoclastic bacteria (OHCB).

Summary: The study found low levels of PAHs in the Knysna Estuary, with TOC, nitrite/nitrate, metals, and environmental properties being primary factors influencing the bacterial community structure. PAH-degrading bacteria make up 0.1% of the community, responding mainly to nitrate, TOC, and salinity. Key PAH degraders like Xanthomonadales, Pseudomonas, and Mycobacterium may help maintain a healthy estuarine ecosystem through metabolization coupled with other biogeochemical processes.

Summary: The cocontamination of PFASs and CAHs in groundwater from a fluorochemical plant was found to have a significant impact on the indigenous microbial community, leading to a decrease in community diversity but an increase in metabolisms associated with contaminant biodegradation. Acinetobacter, Pseudomonas, and Arthrobacter were the dominant genera in the cocontaminated groundwater.

Summary: This study characterized soil bacterial communities and microbial functional genes in a coastal wetland ecosystem across a salinity gradient, revealing the critical role of soil salinity as an environmental filter on microbial diversity and biogeochemical processes. Higher bacterial richness and phylogenetic diversity were observed in saline soils, with specific taxa more prevalent in different salinity conditions. Salinity filtering effect shapes soil bacterial community composition and inhibits soil biogeochemical processes in estuary ecosystems.

Summary: This study compared the differences in PAH degradation between coastal Mediterranean and Antarctic waters and found that microbial degradation of PAHs is much more efficient in the Mediterranean than in the Antarctic. Metatranscriptomic analysis showed significant enrichment of PAH degradation genes in the Mediterranean microbiome, while minimal responses were observed in the Antarctic. These findings suggest that factors such as geographic region, microbial community composition, and pre-exposure history play important roles in predicting PAH biodegradation in seawater.

Summary: Large amounts of metal(loid)s released from abandoned non-ferrous metal smelting sites pose serious environmental risks. This study proposes a weighted comprehensive pollution risk score (CRS) to evaluate the pollution and environmental risk of metal(loid)s, combining two evaluation methods for metal(loid)s pollution and risk index, as well as two microbial activity evaluation methods. The results reveal the metal(loid)s with higher and lower risks in contaminated surface soil, and suggest that microbial activity can serve as a potential indicator of pollution. The study provides useful information for the management and remediation of metal(loid)s polluted sites.

Summary: Although tunas represent a significant part of the global fish economy and a major nutritional resource worldwide, their microbiome remains poorly documented. This study analyzed the taxonomic composition of bacterial communities in the gut, skin, and liver of two widely consumed tuna species. The results showed that the composition of the tuna microbiome was independent of fish sex, but varied according to tuna species and sampling site. The study also discovered a unique and diverse bacterial assemblage in the tuna liver, including potential histamine-producing bacteria.

Summary: Microbial communities in Sepetiba Bay were found to be correlated with metallic contamination and the QR index. Functional analysis revealed different functional patterns in the internal and external sectors of SB. The relative proportions of KEGG pathways and genes associated with metallic homeostasis showed significant differences according to the SB sectors. Additionally, there was a strong correlation between metal resistance genes and antibiotic resistance genes, indicating co-selection by metallic contamination in SB.

Summary: Performic acid (PFA), a new generation of disinfectant, has shown remarkable performance for wastewater treatment. However, its effect on wastewater microbial community and the differences compared to commonly used disinfectants is poorly documented. This study provides an overview of the effects of PFA, chlorine, and UV on microbial diversity and structure in wastewater. The results show that PFA is more effective at inactivating pathogen microorganisms and has the potential for safe wastewater reuse.

Summary: This study aimed to assess the impact of human activity on 18 high-altitude Pyrenean lakes located on both sides of the France-Spain frontier. Sediment cores were collected in summer 2013 and analyzed for the concentration of 24 elements. The results showed that geographical position and lithogenic features influenced the trapping of pollutants in each lake basin. The majority of the lakes exhibited enrichment factor values above 2 for at least one element, indicating historical anthropogenic inputs. The data also highlighted the natural origin of some elements and the significant contribution of mining activities as the main historical source of pollution.

Summary: In this study, the effects of hydrocarbon water-accommodated fraction (WAF) prepared with and without dispersant on benthic microbial communities were investigated. It was found that the contaminated sediment showed less taxa responsive to the addition of both WAF and WAF + dispersant, indicating the presence of hydrocarbon-degrading and dispersant-resistant taxa in the contaminated sediment.
