Summary: This study aimed to quantitatively determine the toxicity of oil remaining in sediment from the Deepwater Horizon oil spill, and found that less than 13% of toxicity tests on benthic species showed toxicity. There was no clear relationship between toxicity test results, oiling category, or measured total polycyclic aromatic hydrocarbons (PAHs).

Summary: The study found that mechanical treatment coupled with vegetation planting in heavily oiled salt marshes showed the most improvement in oiling conditions and vegetation recovery compared to untreated areas or those with mechanical treatment only. This approach was most effective in re-establishing vegetation cover and dominant plant species composition approaching reference conditions.

Summary: The oil spill from the Deepwater Horizon accident has led to a decline in belowground dynamics and soil strength in the coastal wetlands of south Louisiana, causing long-term impacts on marsh resilience. The effects of oiling have persisted for more than a decade and may have implications for other marsh habitats affected by oiling and other stressors.

Summary: The Deepwater Horizon oil spill had multiyear impacts on salt marsh vegetation, with most plant metrics showing significant reductions and requiring three years or longer for recovery. Concerningly, belowground biomass declined over time and may have long-term impacts on ecosystem processes and associated species. Full recovery is likely to exceed 10 years, particularly in heavily oiled marshes.

Summary: Tracking the subsea oil plume during the Deepwater Horizon Oil Spill was conducted using both in situ fluorescence and discrete sample chemical analyses. Discrete samples provided a coarse picture of the oil plume footprint, while in situ fluorescence data improved the resolution. Through analysis of millions of continuous data points, fluorescence was found to serve as a proxy for BTEX concentration.

Summary: The Deepwater Horizon oil spill was the largest and deepest oil accident in US waters, with significant impacts on the marine ecosystem. The released oil underwent various mechanisms, including biodegradation, to transform and disperse, with some sedimenting onto the seafloor. Further research efforts have greatly increased our understanding of the fate of spilled oil, focusing on factors such as photooxidation, microbial communities, and marine oil snow formation.

Summary: Multiple studies have shown that the Deepwater Horizon oil spill results in increased shoreline erosion in coastal marshes. However, this study confirms that the oil spill significantly increased marsh erosion for two years, primarily due to vegetation impacts and reduced soil shear strength. The study also highlights the positive influence of marsh restoration planting in reducing erosion and its long-term benefits.

Summary: This study examines the effectiveness of subsea dispersant injection (SSDI) during the Deepwater Horizon oil spill and evaluates the potential alternatives if dispersants were not used or used more aggressively. The results show that the actual use of SSDI reduced risk to varying degrees, but more effective use of dispersants could have significantly reduced exposures and relative risks across the ecosystem.

Summary: This study investigates how a large-scale ecological disturbance, such as the Deepwater Horizon oil spill, can influence the hantavirus host-pathogen dynamic in the United States. The research findings suggest that habitat is a main driver of hantavirus prevalence in the host and that future disturbances in the region will likely impact the host-pathogen dynamic.

Summary: This study estimated the age-at-sea of weathered oil slicks using a modeling system and used this information to interpret PAH concentration measurements. The study found that the mean percent depletion of PAHs increased with estimated age-at-sea. Alkylated PAHs showed less depletion compared to parent PAHs.

Summary: The Deepwater Horizon disaster had a significant impact on the lung health of common bottlenose dolphins in the northern Gulf of Mexico. The dolphins living within the oil spill footprint showed a higher prevalence of moderate to severe lung disease compared to the dolphins in the uncontaminated area. The presence of lung disease remained persistent and potentially worsened over the years after the spill.

Summary: This study investigated the association between ambient PM2.5, O3 pollution, and ovarian reserve in reproductive-aged Chinese women. The results showed that increased exposure to PM2.5 and O3 was associated with decreased AMH levels, indicating reduced ovarian reserve. Notably, the effects of O3 exposure on ovarian reserve were different from those of PM2.5 exposure.

Summary: Systemic insecticides and rising temperatures have combined effects on the abundance of Odonata nymphs in paddy fields. The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

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.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: The synergistic effects of trace sulfadiazine and cast-iron corrosion scales on the formation of disinfection by-products in drinking water distribution systems were investigated. The presence of magnetite resulted in increased concentrations of DBPs due to the higher microbial activity and enhanced microbial extracellular electron transport pathway.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. 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.
