Summary: The concentrations of polycyclic aromatic compounds (PACs) in Canadian air and deposition show large variations, with higher levels near industrial emitters and lower levels in the Arctic. Reductions in industrial emissions can influence the environment near relevant facilities, but the impact in other areas is modest. Future research is needed to further investigate PACs in Canada.

Summary: Air pollution from PM2.5 causes 7 million deaths annually worldwide, especially affecting children's health in developing countries. Recent studies have shown that these pollutants are linked to diseases beyond lung-related issues, leading to the development of new detection methods. It is necessary to consider the targets for future generation environmental standards.

Summary: The study aimed to investigate the fate, bio-metabolism, and environmental risk of low-ring and high-ring PAHs under long-term irrigation with micro-polluted treated wastewater. Results showed that high-ring PAHs had higher attenuation and adsorption rates compared to low-ring PAHs, with adsorption, biodegradation, and rhizosphere effect playing significant roles in PAH reduction. Functional microorganisms like Pseudomonas, Mycobacterium, and Sphingomonas were found to be positively correlated with PAH degradation, particularly in the rhizosphere. Environmental risk prediction after ten years of irrigation indicated minimal potential risks, suggesting the feasibility of using treated wastewater for garden irrigation.

Summary: The increasing population density and industrialization have had adverse effects on the environment globally, particularly in terms of contamination of soil, agricultural lands, and water bodies with petroleum wastes and hydrocarbon pollutants. Microbial activities have been found to play significant roles in the cleanup of these contaminants, but their burden is expected to increase in the next decade. Therefore, there is a need to rapidly investigate and develop low-cost technologies for eco-sustainable development. This article reviews the applicability of various bioremediation processes, biodegradation pathways, and treatments, highlighting the role of microbial activities in achieving efficient eco-sustainable bioremediation of hydrocarbon pollutants. An integrated bioremediation approach, including biostimulation and bioaugmentation, is recommended for cost-effective removal of toxic petroleum hydrocarbons and their derivatives.

Summary: The palladium-catalyzed cyclotrimerization of ortho-silylaryl triflates is a well-established method for synthesizing polycyclic aromatic hydrocarbons with triphenylene cores. In the reaction of pyrene with o-silylaryl triflates, higher homologues with eight- and ten-membered rings were unexpectedly formed along with the trimer, and a protocol was developed to isolate all members of this series. This novel class of PAHs was thoroughly investigated using various techniques, including X-ray diffraction, UV/Vis and fluorescence spectroscopy, and theoretical calculations. A mechanistic proposal for the formation of all higher cyclooligomers was supported by density functional theory (DFT) calculations.

Summary: In an era of increasing population density and industrialization, the environment is facing growing challenges, such as pollution of soil, agricultural land, and water bodies by petroleum waste and hydrocarbons. Biodegradation emerges as an eco-friendly and cost-effective solution for petroleum-contaminated environments, with microbial communities playing a pivotal role in managing hydrocarbon contamination. Understanding biodegradation mechanisms is essential for optimizing this process. Recent research highlights specific microorganisms capable of efficiently breaking down petroleum hydrocarbons, offering a contemporary perspective on bioremediation of hydrocarbon pollutants. Cooperation among bacterial consortia driven by specific genes guiding bacterial metabolism plays a crucial role in effective cleanup. An integrated approach combining biostimulation and bioaugmentation is recommended for cost-effective and efficient removal from compromised environments.

Summary: Polycyclic aromatic hydrocarbons (PAHs), particularly chrysene, have toxic effects on the liver by increasing relative liver weight and elevated serum ALT levels; the hepatotoxicity of chrysene is dependent on the aryl hydrocarbon receptor (AhR), while Nrf2 plays a crucial role in protecting against oxidative liver injury induced by chrysene.

Summary: Although the association between single PAHs exposure and telomere length has been studied, the relationship between mixed PAHs exposure and telomere length in the general population is still uncertain. This study analyzed 8 PAHs and their correlation with telomere length, finding that mixed PAHs exposure was negatively associated with telomere length. Specifically, 2-napthol and 2-fluorene concentrations showed a significant negative correlation with telomere length. These findings indicate that PAHs may have a negative impact on telomere length in the general population.

Summary: Coal tar pitch, a binder used in the production of anodes for aluminum electrolysis, contains PAHs. The incomplete combustion of PAHs during the baking process leads to emissions. Experimental tests were conducted to examine the effect of temperature and atmosphere on PAH emissions. The results showed that the addition of oxygen significantly reduced the emissions.

Summary: The study evaluated the diversity of cultivable bacteria associated with plants in phytomanaged soils contaminated with mixed trace metals and polycyclic aromatic hydrocarbons in Pierrelaye, France. The focus was on identifying potential bacteria for remediation of contaminated sites, with an emphasis on plant growth-promoting substances and resistance to trace metals. Proteobacteria and Actinobacteria were found to dominate the isolates, with differences in taxonomic diversity observed between plant species and remediation treatments.

Summary: This study found that the concentration of PAHs in environmental media in the Jianghan Plain area is higher than in the Western Hubei Mountains region, and seasonal changes lead to shifts in the roles of soil sources and sinks for PAHs. Simulation revealed that PAHs may have wider and longer effects through water transport, with persistence lasting up to 10 years.

Summary: Oilfield-produced water (OPW) contains a complex mixture of toxic organic and inorganic compounds, including refractory polycyclic aromatic hydrocarbons (PAHs) and polyaromatic hydrocarbons such as BTEX, which have become a global concern. The treatment of OPW is challenging due to the presence of harmful pollutants combined with oil and the generation of recalcitrant by-products. This article critically reviews the feasibility of heterogeneous photocatalysis for OPW treatment, presents the nature and health implications of these compounds, and evaluates pilot and commercial-scale applications of photocatalysis in water treatment.

Summary: Metal trace elements accumulate in soils due to anthropic activities, leading to strategies developed by living organisms to handle metal toxicity. Plants often associate with root endophytic fungi, some of which are associated with metal tolerance. Most reported endophytes have positive effects on their hosts under metal stress, but with varied effects on metal uptake or translocation, without clear taxonomic consistency.

Summary: This study characterized the mycobiome associated with nettle and poplar roots co-occurring at a trace-metal contaminated site. Nettle was found to have a distinct mycobiome dominated by endophytic Pezizomycetes and saprotrophic genus Kotlabaea, while poplar roots were associated with ectomycorrhizal fungi such as Inocybe and Tuber species. The study also revealed some connections between the mycobiomes of poplar and nettle roots, suggesting a need to reconsider fungal networking beyond known mycorrhizal interactions.
