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: This study used AEDT 2.d to estimate the pollutant emissions at Montreal's Pierre Elliott Trudeau International Airport for 2015 and found that the airport's taxi time and atmospheric conditions significantly impact aircraft emissions. Summer conditions reduced NOx emissions and increased CO emissions, while winter conditions decreased HC and CO emissions and increased NOx emissions.

Summary: We investigated the characteristics of new particle formation (NPF) at a rural site downwind of Seoul, Korea, using scanning mobility particle sizer (SMPS) measurements in the range of 10.3-290.8 nm for the period February 2015 through June 2016. The study site is located in a horseshoe-shaped forested valley, over which biogenic emissions likely prevail, and is affected by vehicle emissions coming from the valley entrance. This study found that event days tend to have higher solar radiation, temperature, and wind speed and lower relative humidity than non-event days. During the Korea-US Air Quality (KORUS-AQ) field campaign, the NPF occurrence rate was higher than the seasonal means, likely due to strong solar radiation.

Summary: We conducted field measurements and laboratory evaluations to characterize the physical and chemical properties of aircraft exhaust ultrafine particles near Narita International Airport. The results show that the volatility of aircraft exhaust UFPs is closely related to particle size and temperature.

Summary: There is limited understanding regarding the health impacts of aircraft noise and aircraft-associated ultrafine particles (UFP). Measurements conducted near Gatwick airport in the UK showed a close relationship between particle number concentrations (PNC) and noise levels, with traffic emissions being the major source of PNC. However, UFP is unlikely to be a significant factor in epidemiological studies on aircraft noise and health, as the correlation between UFP and noise is moderate to low. Additionally, meteorological factors should be taken into consideration when studying the short-term associations between aircraft noise and health.

Summary: Airport emissions have a significant impact on atmospheric chemical processes, aerosol microphysical properties, and human health. This study developed a Long-Path Differential Optical Absorption Spectroscopy (LP-DOAS) instrument to measure aircraft emissions at an airport. The results showed that the concentrations of NO2 and SO2 in the airport area were very low, and there was a weak positive correlation between NO2 and SO2 emissions and the age of the aircraft.

Summary: Recent research has shown that airports are significant sources of ultrafine particles (UFP), which can greatly contribute to regional UFP concentrations. However, distinguishing and quantifying the contribution of aircraft emissions to ambient UFP in areas with multiple particle sources is challenging. A car-based mobile measurement campaign near the newly opened Berlin-Brandenburg airport (BER) in Germany was conducted to investigate this issue. The results revealed that airport emissions dominated by elevated total particle number concentrations (TNC) while particle emissions from vehicle traffic were associated with increased CO2 and equivalent black carbon (eBC) concentrations.

Summary: This article proposes the development of an electric vehicle charging station (EVCS) at Shah Amanat (CGP) International Airport in Chattogram, Bangladesh. Using fuzzy logic and RNN-LSTM, a load profile prediction method is developed to consider climate data, battery state of charge (SOC), vehicle occupancy, and flight schedules. The optimal scenario is found to be the grid-tied Photovoltaic (PV) and wind turbine (WT) configuration, with a cost of energy (COE) of $0.041/kWh and an estimated profit of $0.22 M/year.

Summary: Analyzing the molecular composition of ambient ultrafine particles (UFPs) from samples collected near a monitoring station at Frankfurt Airport, this study identified organic compounds related to aircraft lubrication oils, enhancing the source apportionment of UFPs. The developed method uses ultra-high-performance liquid chromatography (UHPLC) and high-resolution mass spectrometry to qualitatively detect molecular markers for jet engine lubricants in UFPs. This research provides valuable insights into the complex chemical composition of UFPs near airports and highlights the presence of specific organic compounds associated with jet engine activities.

Summary: Mobility reductions during the COVID-19 pandemic had a greater and longer-lasting impact on aviation than ground transportation in the United States. A study conducted near Logan Airport in Boston found that ultrafine particle (UFP) concentrations decreased during the pandemic, reflecting the decrease in flight activity and traffic volume. Although traffic volume and particle concentrations returned to pre-pandemic levels, downwind from Logan Airport, particle concentrations remained lower than before the pandemic.

Summary: Airports have a substantial impact on local ultrafine particle concentrations. After the closure of a major airport, particle number concentrations decrease on average by 30%-40%, with maximum values reduced by 2.5 times and variability reduced by 3 times. Downwind of the airfield, average PNCs drop by 70%, maxima by 85%, and variability is reduced by almost 90%.

Summary: This paper investigates the amount of air pollutants emitted by Athens International Airport during the Landing-Take Off phase of flights. The study finds that the airport released significant quantities of CO2, NOx, CO, HC, and PMtotal during its operating time. Measures are planned to reduce the impacts of these pollutants in the future.
