Summary: This study revealed relatively high concentrations of PAHs in sediments, with high molecular weight PAHs more readily redissolving into water, while low molecular weight PAHs were largely unsaturated. Seasonal differences were significant and mainly influenced by sediment properties, marine currents, and water temperature.

Summary: The study revealed that the concentration of polycyclic aromatic hydrocarbons (PAHs) in sediment cores from the southern Brazilian continental shelf is influenced by variations in sources and emissions. The historical deposition reflected the impact of different periods of socio-economic and industrial development on PAH concentrations.

Summary: This study investigated the contamination of polycyclic aromatic hydrocarbons (PAHs) in sediments in rice and crab coculture farming systems. Rice straw biochar was used to inhibit the release and migration of PAHs from sediments, reducing the bioavailability and biological effects of PAHs. The results provide theoretical and technical support for the utilization of straw waste and remediation of PAHs pollution.

Summary: The study investigated historical polycyclic aromatic hydrocarbon (PAH) pollution through sedimentary records in three lakes in China. The results showed that PAH concentrations in sediment are still increasing in these lakes, showing a different trend compared to developed countries. The PAH pollution in South China started earlier in 1850, while the increases in North and Northeast China were observed from 1980. The PAH concentrations were highly correlated with local economic development. The study also identified the main sources of PAHs in lake sediments, including oil leaks, coal and biomass combustion, vehicle emissions, and diagenesis. The findings of this study provide important information for understanding and controlling PAH pollution.

Summary: The study found that the combination of Eisenia fetida and rhamnolipid JBR-425 with a bacterial consortium resulted in increased degradation levels of polycyclic aromatic hydrocarbons (PAH) from oil-contaminated soil. The bacterial consortium degraded 30-89% of selected PAH after 45 days, with chrysene showing the highest degradation (89%) and benzo(a)pyrene the lowest (30%). The earthworm biomass decreased and mortality rates increased with increasing crude oil concentrations, but a 100% survival rate was observed at 1% crude oil exposure, indicating the potential for bioremediation. The combination of E. fetida with the bacterial consortium showed better degradation of PAH, while rhamnolipid JBR-425 coupled with the consortium resulted in significant degradation as well. Overall, the application of the bacterial consortium in conjunction with E. fetida has great potential for the restoration of contaminated soil and ecosystem sustainability.

Summary: Due to its unique environment and geographic location, Svalbard has been identified as a potential pollution reservoir in the Arctic. This study found the presence of microplastics and polycyclic aromatic hydrocarbons (PAHs). Textile materials and fisheries-related debris were identified as possible sources of microplastics and anthropogenic particles. PAHs in soils were mainly derived from traffic emissions and diesel combustion from a local power plant, while ship emissions were the dominant source of PAHs in sediments. Anthropogenic input was confirmed to be higher in Ny-Alesund, while transportation through ocean currents may contribute to the higher abundance of microplastics in Rijpfjorden.

Summary: The correlation between polycyclic aromatic hydrocarbons (PAHs) and economic parameters in Dianchi Lake, Yunnan province, China, was analyzed, showing significant impact of total population, GDP, energy consumption, etc. An artificial neural network (ANN) model was developed to predict the trend in PAH concentrations in the sediments over the next 10 years. Results indicate the importance of economic and climate factors in increasing pollution levels.

Summary: This study examines the effects of biochar derived from sewage sludge (BCSSL) or sewage sludge/biomass (BCSSLW) on the persistence and bioavailability of polycyclic aromatic hydrocarbons (PAHs) in soils with different properties. The results show that the content of organic solvent extractable PAHs decreases when biochar is applied to the soils, depending on pH and feedstock. Similarly, the content of freely dissolved PAHs also decreases. The bioavailability and persistence of PAHs in the biochar-amended soils are closely related to the chemical properties of the soils, as indicated by the significant relationships between PAH content and pH, cation exchange capacity, available nutrients, and dissolved organic carbon.

Summary: Although the oil and gas industry in Northern Alberta has economic benefits, concerns exist over the impact of increased oil production on the environment and human health. This study linked chemical analysis of sediment cores with biological effect assessments, showing the feasibility of evaluating toxicity in river systems.

Summary: Mangrove ecosystems, which are located in the inter-tidal regions between land and ocean, are highly contaminated with polycyclic aromatic hydrocarbons (PAHs). The over accumulation of PAHs in mangrove wetlands poses a serious ecological risk to plant and animal health. This study investigated the migration and transformation of PAHs in sediment and their effects on plants in the presence of biochar derived from Kandelia obovata. The results showed that the biochar amendment decreased the bioavailability of PAHs and improved the stress tolerance and resistance of K. obovata. The findings suggest that a combined biochar-rhizosphere approach could be an effective remediation strategy for alleviating PAH contamination in mangrove sediment.

Summary: The study found that in soils amended with biochars pyrolyzed at low temperatures, the degradation of phenanthrene decreased with the increase of pyrolysis temperature. On the other hand, in soils amended with biochars pyrolyzed at high temperatures, the degradation of phenanthrene increased with the increase of pyrolysis temperature.

Summary: This study experimentally investigates solute leaching under unsaturated conditions, and shows that pressure-wave pulse flux treatment enhances solute displacement compared to drag-dominant continuous flux treatment. The pressure waves induce higher pressure gradients and more uniform wetting, leading to increased solute mass leaching and enhanced transport.
