This study aimed to (1) examine the effects of deposited bitumen (Bit) and asphaltene (Asp) on the North Saskatchewan River (NSR) water quality, focusing on organic carbon and nitrogen; (2) assess the impact of Bit or Asp on sedimentary nitrification; and (3) explore the response of the microbial community to Bit or Asp. Laboratory-scale abiotic (no sediment) and biotic treatments with fresh (NH₃-deprived) sediment and NH₃-enriched sediment were performed at 20 ± 1°C for up to 120 days. Results of the abiotic and biotic treatments with fresh sediment indicated that up to 5 mg/L of total organic carbon (TOC) or nitrogen in the form of NH<sub>3</sub> leached from both deposited Asp and Bit into the overlaying water. Considering the relatively low background concentrations of TOC (2.19 ± 0.29 mg/L) and nitrogen (0.07 ± 0.02 mg/L) in the NSR water, the leached compounds could contribute to the overall organic carbon and nitrogen concentrations in the river. A comparison of the unexposed NH<sub>3</sub>-enriched sediment (Ctl) and Bit-exposed NH<sub>3</sub>-enriched sediment showed that exposure of nitrifying communities did not affect ammonia oxidation but decreased nitrite (50 %) and nitrate (30 %) production. Additionally, the sedimentary microbial community composition altered from its initial composition to a new profile post-exposure to Asp or Bit. The microbial communities also responded differently to Bit exposure compared to Asp exposure. For instance, Asp-exposed sediment was dominated by a diverse group of taxa, while Bit-exposed sediment was mainly dominated by phylum Proteobacteria post-exposure. Overall, the findings indicate that deposited Bit and Asp could contribute organic carbon and nitrogen to the NSR water, impaire the sedimentary nitrification process and alter microbial community composition in the sediments.</div></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"19 ","pages":"Article 100619"},"PeriodicalIF":0.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143350497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods for assessing odor impact in such situations have to overcome points of criticism, such as the lack of reliability and subjectivity in sensory analysis. The aim of this study was to validate an improved procedure for investigating odor plumes by trained assessors. In addition to the widespread approach, which focuses on odor frequency, we combined the odor parameters of intensity and frequency. Due to the relevance of weak and mixed odors, very weak (i.e., perceptible) odors were included, rather than focusing only on recognizable odors (clear, distinct perception). On two farms, a tracer gas approach was implemented to provide an objective measure of dispersion. Comparable spatial patterns in odor parameters (frequency, frequency-weighted odor intensity) and tracer gas concentrations provide a number of key findings to consider in odor assessment of areal sources. Two spatial source configurations were studied—the animal part and the biogas part nested or spatially separated—and discriminated by dosing two different tracer gases. In nested configurations, tracer gases mix homogeneously in the plume and therefore only the combined source can be mapped. By contrast, for spatially separated sources, each position in the plume receives an individual exposure to tracer gases and odor, depending on source arrangement, wind direction, and the adjacent buildings. The presented approach can be extended to reliably track and assign more complex situations. The improved procedures will support objectifying odor impact assessment and pave the way for developing appropriate mitigation strategies.</div></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"19 ","pages":"Article 100616"},"PeriodicalIF":0.0,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143419593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The toxicity of hexavalent chromium, in particular, underscores the need for effective remediation strategies to mitigate its harmful effects. This review aims to evaluate various remediation methods for chromium-contaminated soils, including engineering, bioremediation, chemical, and agricultural approaches. It synthesizes existing literature to identify advancements and challenges associated with each method, focusing on their effectiveness, duration, and environmental impact. The findings indicate that solidification/stabilization techniques are effective in sequestering chromium; however, they raise concerns regarding long-term stability. Bioremediation, which employs hyperaccumulator plants and specific microorganisms, shows promise in reducing hexavalent chromium to its less toxic trivalent form, although it is often constrained by prolonged remediation times. Chemical methods, while effective, encounter challenges related to dosage control and the management of secondary pollutants. Agricultural strategies, including optimized land use and fertilization practices, can help mitigate chromium pollution but require careful management to enhance their efficacy. This review highlights the importance of integrating multiple remediation techniques to achieve optimal results. It emphasizes the potential of eco-friendly methods such as phytoremediation and constructed wetlands, which not only remove pollutants but also improve soil quality. Additionally, the study underscores the necessity of incorporating economic and environmental sustainability assessments into the development of comprehensive remediation strategies. The review concludes that an integrated approach combining engineering, bioremediation, chemical, and agricultural methods is essential for effectively managing chromium contamination in soils.

The study investigates how engineering design factors (such as the wavelength and irradiance of UV-C LEDs) and experimental parameters (such as solvent and reactor volume) affect the degradation kinetics of a photolyzable nitrogenous DBP, dibromoacetonitrile (DBAN). UV-C LEDs with characteristic peak wavelengths of 265, 275, and 280 nm and output power of 32–40 mW were studied to degrade DBAN, where acetone and methyl tert-butyl ether (MtBE) were used as the preparation solvents. Quantum yield fluence-based kinetic rate constants (k<sub>f</sub>), and electrical energy per order (EEO) were calculated for different experimental conditions. EEO was inversely related to quantum yield and lowest for the 265 nm high-power UV-C LED at 80.43 kWh/m<sup>3</sup>. A significant finding is that incident irradiance greatly impacted the degradation kinetics even when normalized by fluence. The 265 nm high-power LED resulted in 2.3-times higher quantum yield and fluence-based degradation kinetics than the 265 low-power LED and a corresponding 3.5 times lower EEO despite the same wavelength of irradiance. Lastly, we demonstrate that the solvent selected significantly impacts kinetics, where the degradation of DBAN with acetone is 2.28-times greater than with MtBE at the 275 nm wavelength. Indirect photochemical reactions increase observed degradation kinetics; therefore, solvents should be carefully selected for photochemical studies targeting water treatment.

Recent studies suggest use of a finer fraction (<150 μm) may be more representative of exposures, but data documenting a difference in lead concentrations between these two size fractions are limited. Site investigations may require analysis of hundreds of samples. Screening these samples to <150 μm requires significantly more sample mass and laboratory processing time and space.
