Summary: The Permian Basin is the largest and fastest growing oil and gas producing region in the US, with 1100 unique methane emission sources identified through airborne surveys. Most emissions come from O&G production, and frequent high-resolution monitoring is needed to accurately pinpoint persistent leaks.

Summary: Methane emissions along the natural gas supply chain play a critical role in the climate benefits of switching from coal to natural gas in the power sector. For Germany, with methane leakage rates below specific break-even levels, transitioning to natural gas can significantly reduce CO2-equivalent GHG emissions.

Summary: The development of advanced biofuel production facilities is still in its early stages and may face challenges in obtaining air permits due to being novel emission sources. In this study, we analyze the emissions of an advanced biorefinery that produces renewable diesel blendstock from lignocellulosic biomass and provide insights for developers and regulators to mitigate investment risks and develop permitting strategies.

Summary: The study investigated the pollution emissions and their impact on air quality in the surrounding areas of Beijing Daxing International Airport. The results showed that the airport's emissions had the highest impact on NOX concentrations, especially under unfavorable meteorological conditions. Currently, the airport's contribution to pollution in the surrounding areas is low, but with the increase in flight numbers, its impact on air quality needs to be addressed.

Summary: Emissions of fine particulate matter, precursors to tropospheric ozone, and their impacts on human health, ecosystems, and climate are important considerations. Quantifying these impacts accurately requires accurate, transparent, complete, comparable, and consistent emission inventories. The IPCC is developing a new methodology report to better quantify the emissions and impacts of these pollutants. Coordination between greenhouse gas and air pollutant inventory efforts can have benefits, but differences in methodologies and applications must be considered.

Summary: Environmental concerns have become central for many bus companies, but estimating pollutant emissions can be difficult due to various reasons. To assist transit operators in evaluating emissions from fleets with a significant number of old buses, an integrated, user-friendly model called iGREEN has been introduced. Results from two case studies highlight the challenges posed by a large number of obsolete vehicles still in operation when calculating emissions.

Summary: Shale gas exploitation generates flowback and produced water (FPW) containing complex organic compounds, some of which are persistent, mobile and toxic (PMT) or very persistent and very mobile (vPvM). A literature review identified 162 organic compounds in FPW, with only 22 considered PMT/vPvM substances. Examples of PMT substances in FPW include anthracene, 1,4-dioxane, and 1,4-dichlorobenzene. Prioritizing risk management and monitoring of PMT/vPvM compounds in FPW is crucial for protecting regional water resources.

Summary: Starting from 2008, the expansion of oil and natural gas production in Texas caused concern about its impact on air quality, particularly in the Dallas-Fort Worth metroplex. Through analyzing 6-12 years of hourly air monitoring data from 15 sites, it was found that the concentrations of lighter alkane hydrocarbons were most affected by the number of gas wells, while heavier alkane concentrations were influenced by condensate production and urbanicity. The study also showed that the levels of organic compounds did not exceed the air monitoring values for human health or odor based on comparisons with Texas standards.

Summary: Vehicle emissions have a significant impact on urban air pollution in Chinese megacities. This study established a 5-year vehicle emission inventory and explored the relationship between vehicle emissions and air quality. The results showed that different types of vehicles contribute differently to pollution, and vehicle emissions exacerbate the formation of harmful gases in the atmosphere.

Summary: This review investigates the effects of toxic air pollutants on the occurrence of multiple sclerosis (MS). The study finds that toxic air pollutants are major factors in the development and spread of chronic diseases and multiple sclerosis. Industries, cars, power plants, and excessive consumption of fossil fuels are identified as the main sources of emission for these pollutants.

Summary: The emissions from maritime transportation in the Strait of Gibraltar can be significantly reduced by declaring it an Emission Control Area (ECA). Using the SENEM1 emissions model, this study compared the current situation with a simulation of the Strait as an ECA, showing a potential reduction of up to 75.8% in NOx, 73.4% in PM2.5, and 94% in SOx emissions. This calls for a recommendation to designate the Strait of Gibraltar as an ECA by the International Maritime Organization (IMO) and responsible governments.

Summary: The study demonstrates that reducing emissions from all anthropogenic sources is the most effective way to decrease severe air pollution events in the long term. In the short term, accurate weather forecasting systems and effective emergency emission reduction measures can mitigate the scale and duration of pollution events. However, preventing events caused by natural sources affected by climate change remains unclear.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
