One of the most persistent environmental pollutants known as polycyclic aromatic hydrocarbons (PAHs), are pervasive throughout the world. Polycyclic aromatic hydrocarbons pose a serious health threat to a variety of life forms because of their mutagenic, teratogenic, immunotoxicogenic, and/or carcinogenic properties. The majority of PAHs production comes from both natural and human sources, such as forest fires, volcanic emissions, coal, oil, and petroleumbased goods like gasoline. Because PAHs show very high persistence, aquatic and non-aquatic animal species can easily acquire their residues in the environment, either directly from the water or indirectly through their food. Because of this, the current review focuses on the main PAHs emission sources, transformations, occurrences in ecosystems, and harmful effects on aquatic animals, with an emphasis on fish. Also, eco-friendly biological treatment methods for PAHs remediation are thoroughly discussed. These methods include microbial remediation (bacterialremediation, myco-remediation, and vermi-remediation) and Phyto-remediation techniques (active carbons, rhizo-remediation, and medicinal plants).

“…Previous studies found that reactive Fe minerals and OM might be the vital constituents in soils for O 2 system to evolve reactive species and attain the transformative removal of pollutants. 55,56 Likewise, these reactive constituents might be a PS activator due to higher redox potential and smaller peroxide bond dissociation energy of PS (2.08 V, 92 kJ mol −1 ) than that of O 2 (1.23 V, 498.36 kJ mol −1 ). In our study, OM removal through H 2 O 2 treatment had negligible influence on SMX degradation in the IPS/PS system; OM removal led to a slight decrease of SMX degradation in IRS1/PS (11.0%) and IRS2/ PS (15.6%) systems (Figure 2b).…”

Naturally occurring iron (Fe) minerals have been proved to activate persulfate (PS) to generate reactive species, but the role of soil-inherent Fe minerals in activating PS as well as the underlying mechanisms remains poorly understood. Here, we investigated sulfamethoxazole (SMX) degradation by PS in two Fe-rich soils and one Fe-poor soil. Unlike with the radical-dominant oxidation processes in Fe-poor soil, PS was effectively activated through nonradical pathways (i.e., surface electron-transfer) in Ferich soils, accounting for 68.4%−85.5% of SMX degradation. The nonradical mechanism was evidenced by multiple methods, including electrochemical, in situ Raman, and competition kinetics tests. Inherent Fe-based minerals, especially those containing Fe(II) were the crucial activators of PS in Fe-rich soils. Compared to Fe(III) minerals, Fe(II) minerals (e.g., ilmenite) were more liable to form Fe(II) mineral-PS* complexes to initiate the nonradical pathways, oxidizing adjacent SMX via electron transfer. Furthermore, mineral structural Fe(II) was the dominant component to coordinate such a direct oxidation process. After PS oxidation, lowcrystalline Fe minerals in soils were transformed into high-crystalline Fe phases. Collectively, our study shows that soil-inherent Fe minerals can effectively activate PS in Fe-rich soils, so the addition of exogenous iron might not be required for PS-based in situ chemical oxidation. Outcomes also provide new insights into the activation mechanisms when persulfate is used for the remediation of contaminated soils.

Polycyclic aromatic hydrocarbons (PAHs) are omnipresent toxic pollutants found in numerous ecosystems, including soil, water, and living organisms. Due to their hydrophobic nature, PAHs tend to accumulate in aquatic environments, leading to high concentrations in aquatic sediments and subsequent bioaccumulation in organisms. This accumulation poses substantial risks to humans and aquatic life. Recent advances in photocatalytic methods, particularly those using nanocomposite materials, have shown promising outcomes in the degradation of PAHs. Photocatalysis, a process that uses UV and visible light to accelerate a chemical reaction, is effectively breaking these harmful compounds. This review focuses on the recent advances in the degradation of PAHs, the toxicological effects of PAHs on living organisms, and the mechanisms underlying nanocomposite‐based photocatalysis. The utilization of nanocomposite for photocatalysis is an eco‐friendly substitute to traditional methods for remediating PAH pollution in the ecosystem. This green approach using nanocomposite‐based photocatalysis offers a sustainable and effective approach for the degradation of PAHs.
