Background: Secondary organic aerosols (SOAs) formed from anthropogenic or biogenic gaseous precursors in the atmosphere substantially contribute to ambient fine particulate matter [PM ≤2.5μm aerodynamic diameter (PM2.5)] burden, which has been associated with adverse human health effects. However, there is only limited evidence on their differential toxicological impact. Objectives: We aimed discriminate effects of generated by atmospheric aging combustion soot particles (SPs) (β-pinene)...
Sulphur Emission Control Areas (SECAs), mandated by the International Maritime Organization (IMO), regulate fuel sulphur content (FSC) to mitigate environmental and health impact of shipping emissions in coastal areas. Currently, FSC is limited 0.1% (w/w) within 0.5% outside SECAs, with exceptions for ships employing wet scrubbers. These scrubbers enable vessels using non-compliant fuels such as high-sulphur heavy oils (HFOs) enter SECAs. However, while reduction via effective, their...
The health effects of exposure to secondary organic aerosols (SOAs) are still limited. Here, we investigated and compared the toxicities soot particles (SP) coated with β-pinene SOA (SOAβPin-SP) SP naphthalene (SOANap-SP) in a human bronchial epithelial cell line (BEAS-2B) residing at air–liquid interface. SOAβPin-SP mostly contained oxygenated aliphatic compounds from photooxidation, whereas SOANap-SP significant fraction aromatic products under similar conditions. Following exposure,...
In this study, we propose a novel long short-term memory (LSTM) neural network model that leverages color features (HSV: hue, saturation, value) extracted from street images to estimate air quality with particulate matter (PM) in four typical European environments: urban, suburban, villages, and the harbor. To evaluate its performance, utilize concentration data for eight parameters of ambient PM (PM1.0, PM2.5, PM10, particle number concentration, lung-deposited surface area, equivalent mass...
A SEM/EDX based automated measurement and classification algorithm was tested as a method for the in-depth analysis of micro-environments in Munich subway using custom build mobile measurements system. Sampling conducted at platform stations, to investigate personal exposure commuters particulate matter during stays. EDX spectra morphological features all analyzed particles were automatically obtained classified on pre-defined chemical boundaries. Source apportionment individual particles,...
A mobile measurement system for complex characterization of particulate matter (PM) was developed together with the proposed methodology and applied in subway Munich, Germany. The main objectives were to observe spatio-temporal variability PM, personal exposure, identify hot-spots pollution sources. Particle mass (PMx) number (PNC) concentrations, equivalent black carbon (eBC) measured at 0.1–1 Hz. On U5 line, PM10, PM2.5 PM1 concentrations platforms ranged from 59–220, 27–80, 9–21 μg m−3,...
A novel marker approach can detect individual particles from ship emissions in the atmosphere via resonant ionization of aromatic hydrocarbons.
Single-particle mass spectrometric information on PAHs in ship emissions can indicate the type of fuel used.
Humic-like substances (HULIS), known for their substantial impact on the atmosphere, are identified in marine diesel engine emissions obtained from five different fuels at two loads simulating real world scenarios as well application of wet sulfur scrubbers. The HULIS chemical composition is characterized by electrospray ionization (ESI) ultrahigh resolution mass spectrometry and shown to contain partially oxidized alkylated polycyclic aromatic compounds aliphatic compounds, both including...
Abstract. The portable microAeth® MA200 (MA200) is widely applied for measuring black carbon in human exposure profiling and mobile air quality monitoring. Due to it being relatively new on the market, field lacks a refined assessment of instrument's performance under various settings data post-processing approaches. This study assessed real-time determine suitable noise reduction algorithm an urban area, Augsburg, Germany. Noise negative value mitigation were explored via different methods...
Emissions from small gas turbine engines pose environmental and health risks they are, dependent of engine type manufacture date, not regulated or only subject to smoke emission standards resulting in a lack detailed characterization. This study examines the behavior an Allison 250-C20B turboshaft when powered by different blends (30, 50, 100%) Hydroprocessed Esters Fatty Acids (HEFA) based Sustainable Aviation Fuel (SAF). The change power is linked differences gaseous particulate matter...
Abstract Ship traffic substantially contributes to air pollution, thus affecting climate and human health. Recently introduced regulations by the International Maritime Organization (IMO) on fuel sulfur content (FSC) caused a shift in marine onsumption from heavy oils (HFO) diesel-like distillate fuels, but also alternative hybrid fuels operation of scrubbers. Using multi-wavelength thermal-optical carbon analysis (MW-TOCA), our study provides emission factors (EF) carbonaceous aerosol...
Abstract Ship emissions cause serious environmental impacts and adverse effects toward human health. Therefore, the International Maritime Organization (IMO) restricted fuel sulfur content (FSC) of marine fuels: FSC must be <0.5% m/m or <0.1% in emission control areas, covering a range fuels from distillate diesel-like to low-sulfur heavy oils (HFOs). As result, ship emissions, e.g., oxides particulate matter (PM) have been reduced. However, how correlates with toxicological potential...
