| Huaqi Sun (2024) | Simulating the OH-initiated photooxidation of decane under urban NOx conditions Decane can be a precursor for the formation of secondary organic aerosol under urban NOx conditions. This thesis focussed on the OH-initiated oxidation of decane in the controlled set-up of a flow tube. Products in gas- and particle-phase were identified with various methods. |
| Hai Anh Nguyen (2023) | Experimental Simultaneous Quantification of Water States, Fluxes, and BVOC Exchange in Agricultural Soil In this thesis, the influences of BVOCs concentration in the atmosphere, the soil water content, and the hysteresis in the soil on the BVOCs exchange in agricultural soil were investigated. During the drying-rewetting periods of pre-saturated soil, the BVOCs mixing ratios before and after entering the soil chamber, as well as the soil water retention, were simultaneously measured. |
| Myriam Younes (2023) | Microplastics in the atmospheric deposition of Bayreuth, Germany Microplastics are small pieces of synthetic polymers with particle sizes of less than 5000 µm. These particles can be transported through the atmosphere and subsequently be deposited far away from their sources, leading to contamination of even remote areas. To date, the relative importance of wet and dry desposition processes for microplastic removal from air remains poorly understood. To address this research gap, we collected and analyzed monthly deposition samples in 2022 and 2023 in Bayreuth, Germany. |
| Finja Löher (2023) | Assessing yields and reactivity of photooxidation products along the urban-remote gradient by controlled experiments and SPME-GC-MS with on-line derivatization Atmospheric photooxidation of volatile organic compounds (VOC) has significant effects on the formation of tropospheric ozone and secondary organic aerosol (SOA) as well as for recycling of the OH radical, yet many underlying processes and dependencies are not sufficiently understood to date. In this master thesis, the photooxidation of mixtures of anthropogenic and biogenic VOC is studied. |
| Alexander Weiß (2023) | Performance investigations of mobile analyzers for ultrafine particles in field and laboratory as part of the UFP-MUC project In dieser Studie werden drei mobile Partikel-Zähler für die Beobachtung von atmosphärischem Ultrafeinstaub in Feld und Laborexperimenten getestet und evaluiert. |
| Julia David (2022) | Ozone risk = Urban risk? Investigations of the non-linear tropospheric ozone production along an urban-rural gradient Tropospheric ozone is one of the pressing problems related to air pollution worldwide and is non-linearly linked to NOx, ROx, and VOC concentrations in ambient air. This work aims to explore trends in surface ozone concentrations on a temporal and spatial scale. Therefore, datasets from urban, suburban and rural areas will be compared that are available from the Umweltbundesamt (UBA), Bayrisches Landesamt for Umwelt (LfU) and the Bayreuth Center of Ecology and Environmental Research (BayCEER) . |
| Kenny Rautenberg (2022) | What is the link? Fingerprint analysis of Polycyclic Aromatic Hydrocarbons (PAHs) in soil and airborne particles Polycyclic aromatic hydrocarbons (PAHs) are major organic pollutants which are ubiquitously spread around the globe and are primarily emitted via anthropogenic combustion processes. They have been found in various environmental media and most substances of this group exert a carcinogenic on living organisms including humans. PAHs make up a majority of the organic fraction in atmospheric particles, particularly in ultrafine particles (UFP) – particulate matter with a diameter of ≤ 100 nm. Due to their small size, UFP pose a risk for harmful effects on the human body and the earth’s environment. The aim of this master thesis is to implement and validate a method for the filter extraction and subsequent GC-MS analysis for ambient UFP samples focussing on PAHs. |
