Summary: This study calculated the nitrogen isotope effects between NOx and p-NO3- and reevaluated the relative contributions of major fossil and non-fossil fuel NOx emissions at different sites. The results indicate that non-fossil fuel NOx emissions generally have higher contributions and should be emphasized in future emission management.

Summary: The study investigates sources and production of atmospheric nitrate in coastal East Antarctica using isotopic composition. It found that atmospheric nitrate in summer is associated with snowpack emissions of NOx and in winter, there is mixing between stratospheric and tropospheric sources contributing to nitrate. The study also suggests oxygen isotopes of nitrate could be more sensitive to changes in surface ozone compared to bromine oxide concentrations.

Summary: This study characterized the concentrations and spatiotemporal patterns of ambient air polycyclic aromatic compounds in the Athabasca oil sands region between 2011 and 2015. Alkylated polycyclic aromatic hydrocarbons were found to be the majority of PACs in air, with concentrations varying spatially and seasonally. PAC concentrations measured during wildfire events were the highest and enriched in higher molecular weight alk-PAHs.

Summary: This study used a deposition modeling framework to generate gridded dry, wet, and total deposition fluxes of 27 particulate elements over the Canadian Athabasca oil sands region and its surrounding areas for the years 2016-2017. The deposition of individual elements was primarily governed by their respective concentrations and wet deposition was the dominant deposition type in the region. The total deposition decreased rapidly within a short distance from the oil sands mining area.

Summary: This study investigated the occurrence and characteristics of naphthenic acids (NAs) in boreal wetlands in the Athabasca oil sands region of Alberta, Canada. The results showed that NAs in surface waters were mainly derived from oil sands deposits, but similar patterns were also observed in undeveloped natural wetlands.

Summary: Shallow groundwater nitrate nitrogen concentrations in agricultural areas exhibit high spatial and intra-annual variability. A random forest (RF) model was used to predict the concentrations based on field observations and identified groundwater nitrite and ammonium as important factors. The model showed satisfactory prediction accuracy and improved understanding of groundwater pollution.

Summary: Storm events have a significant impact on the export of atmospheric nitrate (NO3-) in urban watersheds and larger rainfall events are more effective in exporting atmospheric NO3-. Management practices that reduce the hydrologic connectivity of impervious surfaces can help mitigate the impact of storm events on NO3- export from developed watersheds.

Summary: With industrial development in the Athabasca oil sands region (AOSR) in northern Alberta, the atmospheric deposition of polycyclic aromatic hydrocarbons (PAHs) has increased. The main source of PAHs to moss in the region is the deposition of particles from the atmosphere. PAH concentrations in the near-field AOSR sites were significantly higher than those in the far-field AOSR sites or reference sites in Alberta. The major sources of PAHs in the AOSR were estimated to be delayed petcoke and fine tailings. Dust control measures should be considered to protect human and environmental health, especially in the northern quadrant of the AOSR.

Summary: Nitrogen isotope discrimination (ΔN-15) can be used as an indicator of nitrogen use in plants. In this study, a simple isotope mass balance (IMB) model was used to analyze the nitrogen use efficiency of different canola lines. The results showed that commercial hybrids had a higher capability to utilize ammonium as their sole nitrogen source compared to open-pollinated lines.

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: 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.
