Summary: The forensic evaluation of PAHs in nearshore sediments in San Francisco Bay identified potential source relationships with historical MGP operations and creosote. Using diagnostic source ratio analysis, distinct source signatures were determined, with two exhibiting pyrogenic character consistent with MGP sources and one related to creosote. Urban influence was identified as a significant source of PAHs in the investigation area sediment, along with nonpoint and potential unidentified point sources.

Summary: In this study, DNA-stable isotope probing and high-throughput sequencing were used to investigate the influence of biochar on phenanthrene (PHE) degradation, the active PHE-degrading microbial community, and PAH-degradation genes. The results showed that the addition of biochar significantly decreased PHE biodegradation and bioavailable concentrations, and altered the composition and abundance of the PHE-degrading microbial community. Furthermore, new microbial strains and genes involved in PHE degradation were identified.

Summary: This study investigated the sorption behaviors of organic pollutants on microplastics and their bioaccessibilities and cancer risks in the human body. The results showed that the sorption capacity of microplastics was related to their hydrophobicity, and the sorbed pollutants had high bioaccessibilities in gastrointestinal fluids. Moreover, the cancer risks posed by these pollutants on microplastics were found to be significant.

Summary: Up to 400 million tons of carbon from airborne semivolatile aromatic hydrocarbons are deposited into the oceans annually, making it the largest known source of anthropogenic organic carbon in the ocean. Microbial degradation is an important process for removing these pollutants in surface waters, but has not been extensively studied in polar environments. This research investigates the response of Antarctic microbial communities to polycyclic aromatic hydrocarbons (PAHs) in the sea-surface microlayer (SML) and the subsurface layer (SSL). The study finds that microbial degradation rates are higher in the SML, especially for hydrophobic and particle-bound PAHs. The composition of particle-associated bacteria in the SML also significantly changes after 24 hours of PAHs exposure. This study highlights the crucial role of bacterial populations in the SML, particularly those associated with particles, in removing aromatic hydrocarbons in the oceans.

Summary: In this study, DNA-SIP technology was used to detect active BaP-degraders, finding that the diversity of degrading microorganisms was highest in paddy soil. The active BaP-degraders in the mixed microbiome were found to be both identical and unique compared to those in paddy soil, with functional genes of PAH-ring hydroxylating dioxygenases positively related to BaP removal. Gram-positive and Gram-negative bacteria were both found to be active BaP degrading bacteria in the study.

The results obtained from XAD-4 extraction showed a good correlation with the degraded amounts, suggesting that XAD-4 extraction could be a simplified, easier, and lower cost method for bioavailability assessment.

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: The study found that using PAH-ATP modified bacteria can effectively emulsify oil and facilitate subsequent biodegradation. PAH-ATP can capture bacteria to the surface of oil droplets, significantly improving the degradation efficiency of oil pollution. Furthermore, the presence of PAH-ATP does not inhibit the activity and reproduction of bacteria.

Summary: The contamination of aquatic ecosystems by hydrophobic organic contaminants (HOCs) is often evaluated based on their concentrations in riverbed sediment and suspended particulate matter (SPM). However, the total HOC concentration (C-TOT) in sediment or SPM has limited value in assessing the exposure of benthic or pelagic organisms. The accessible HOC concentration (C-AS) provides a useful parameter for quantifying the overall pool of HOC available for partitioning to the water phase or biota. This study compared C-TOT and C-AS in SPM and sediment samples collected from the Danube River and found that they provide complementary but not interchangeable information on HOC contamination.

Summary: The impact of wood ash on metal uptake and transfer factor of lettuce grown on soil amended with poultry litter, digestate, and its fraction was evaluated. The results showed that wood ash had positive effects on the properties of the amended soil and led to better lettuce productivity, particularly when used with poultry litter. The organic treatments had lower potential toxicity in lettuce compared to inorganic fertilizer. Therefore, wood ash can be used as a nutrient booster for organic fertilizers and an alternative to inorganic fertilizers for leafy vegetables.

Summary: This study investigated the impact of white-rot fungi (WRF) on enhancing phenanthrene catabolism in soil over time. The results showed that soils amended with WRF immobilized on spent brewery grains (SBG) had reduced lag phases and increased mineralization rates of 14C-phenanthrene compared to other WRF amendments. Pleurotus ostreatus and Phanerochaete chrysosporium had a stronger influence on biodegradation, while Trametes versicolor showed the best results among the WRF amendments. Fungal enzyme activities increased in all amended soils and were positively correlated with the mineralization extents of 14C-phenanthrene.

Summary: This study demonstrates the advantages and limitations of using passive samplers for monitoring polar contaminants in surface waters. The results show that POCIS has a higher quantification frequency for most contaminants compared to spot samples, and it lowers the limits of quantification. POCIS is able to capture short-duration and high-intensity contamination events, and it provides more reliable annual monitoring and assessment of environmental quality compared to spot sampling.

Summary: A study investigated the potential negative impacts of the delousing treatment used in aquaculture on the marine environment. Laboratory experiments were conducted to study the acute and sublethal effects of exposure on northern shrimp. Environmental concentrations were determined by water sampling and sediment analysis. Ecotoxicological analyses revealed high sensitivity of the shrimp to the delousing treatment, and field measurements and modeling predicted concentrations that could cause negative effects on the shrimp up to a certain distance from the point of release.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
