Hierzu werden chemisch-physikalische Einflüsse (Bewitterung) und mikrobielle Beanspruchungen an Modellmaterialien evaluiert. So werden die Freisetzungsraten von Schadstoffen in Abhängigkeit der Beanspruchung beschrieben. Als Modellmaterialien kommen die Polymere Polycarbonat, Polytetrafluorethylen, Polystyrol und Polypropylen zum Einsatz. Synergistische Effekte der Bewitterungsparameter und der mikrobiologischen Beanspruchung sollen dabei ebenso betrachtet werden, wie die gezielte Alterung. Auch findet eine Beschreibung des Verhaltens der ausgetragenen Schadstoffe in den Umweltkompartimenten Boden oder Wasser statt. Hier sind mit Hilfe der zu entwickelnden Screening- und non-Target-Analyseverfahren die Transformation und der Metabolismus durch Mikroorganismen zu beschreiben. Aus den Ergebnissen sollen Korrelationen zwischen den künstlichen Alterungsverfahren und realen Szenarien abgeleitet werden, die es gestatten, Schnellprüfverfahren zu etablieren, die die Simulation der realen Beanspruchungen im Zeitraffermodell anwendbar machen. Somit sollen standardisierbare Schnellbeanspruchungs-verfahren erarbeitet werden, die als Prüfeinrichtungen etabliert werden und von externen Auftraggebern zur Prüfung der Umweltbeständigkeit und -verträglichkeit von neuen Materialien genutzt werden können. Die Umweltwirkungen (chemisch-physikalisch und mikrobiologisch) sollen so definiert eingesetzt werden, dass eine reproduzierbare Prüfung möglich wird. Aus diesen Verfahren und Methoden sollen Normen abgeleitet werden, die eine standardisierte Materialprüfung ermöglichen. T2 - 46.

Toxicological relevant metals can possibly accumulate within the food web and cause harmful effects. Diatoms are a test system in ecotoxicology. Toxicological effects weaken the growth of algae which is by default investigated by means of fluorescence detection. On basis of the expose concentration as well as obtained fluorescence data potential threshold exceedance in e.g. surface waters is assessed. However, this approach does not allow for the determination of “real” accumulated metal concentration in diatoms. Common approaches are based on bulk analysis via e.g. ICP-MS, ICP-OES or AAS. But, biological variability is completely disregarded. To tackle this problem, alternative approaches are highly needed. Within the last years, sp-ICP-MS for nanoparticle as well as single cell analysis turned out as a powerful technique to analyze metal contents as well as size distributions on broad size range. But, common ICP-MS systems do not allow for multi-element detection within single particle/cell events. Thus, simultaneous MS detection devices are needed - just recently, ICP-ToF-MS experienced a revival. Within our previous work, we developed an automated sample introduction system based on a HPLC system on-line with single particle-ICP-MS, which allowed for ionic background separation and single algae analysis. However, for unambiguous tracing several fingerprint elements and multielement analysis in single algae (diatoms) is needed. Thus, we coupled our previous setup on-line to ICP-ToF-MS. Test diatom species were exposed to test substances (Zn) as well as nanoparticles (FeNPs). The developed setup allowed for a fast, automated and multielement analysis in single diatoms. Furthermore, we combined our approach with multivariate data assessment - multielement detection of characteristic fingerprint elements allowed for an unambiguous diatom tracing. Clustering of diatoms according to metal exposure concentration levels was enabled. Our approach is a new potential tool in ecotoxicological testing. T2 - 53.

They dominate – often together with bacteria and algae in sub-aerial biofilms – a range of hostile environments including natural and man-made ones, from salterns to dishwashers, roofs and solar panels. Because of lacking genetic tools and the slow growth of most isolates, the genetic bases for these specific properties are largely unknown. The rock-inhabiting fungus Knufia petricola (Eurotiomycetes, Chaetothyriales) exhibits all characteristics of microcolonial black fungi and was selected as recipient for genetic engineering to study gene functions and genetic interactions. Different variants of green and red fluorescent proteins were successfully expressed indicating that fluorescence microscopy using genetically encoded fluorescent proteins and fluorescent dyes enables various cell biology approaches. Furthermore, genes of biosynthetic pathways (DHN melanin, carotenoids, uracil, adenine) were successfully mutated by applying traditional gene replacement and plasmid-based or ribonucleoprotein (RNP)-based CRISPR/Cas9 or silenced by RNA interference (RNAi). The availability of this advanced and efficient genetic toolbox and the annotated genome sequence of strain A95 makes K. petricola an excellent model for exploring the secrets of microcolonial black fungi.

Up to now, the OECD identified and categorized 4730 per- and polyfluoroalkyl substances-related CAS numbers. Especially in the field of technical applications (e.g. surface coatings, fire extinguishing foams) as well as pharmaceuticals, fluorinated substances gain in importance. Thus, an increasing release of fluorinated compounds into the environment is expected. The high environmental persistence of perfluorinated compounds leads to the risk of bioaccumulation. Partially fluorinated substances (polyfluorinated compounds) undergo degradation; thus, further possible fluorine species occur, which may exhibit different toxic/chemical properties. However, current target methods (e.g., HPLC/MS-MS) are not applicable for a comprehensive screening as well as assessment of pollution. Thus, the poster presents a new sum parameter method for quantitative determination of extractable organically bound fluorine (EOF) in surface water samples. The method is based on solid-phase extraction (SPE) for fluorinated compounds as well as quantitative separation of interfering inorganic fluoride in combination with high-resolution-continuum source graphite furnace molecular absorption spectrometry (HR-CS GF MAS) for quantitative analysis. By means of this technique, the detection of high resolution molecular absorption spectra (MAS) is enabled upon the addition of a modifier and the formation of a diatomic molecule (e.g. GaF) After successful optimization of the SPE procedure (maximum concentration of extractable organic fluorine), enrichment factors of about 1000 were achieved, allowing for highly sensitive fluorine detection. Next to a species-unspecific response, limits of detection in the low nanogram per liter range were achieved and real surface water samples were analyzed. EOF values in the range of about 50-300 ng/L were detected. The developed method allows for a fast and sensitive as well as selective screening of organically bound fluorine (EOF) in surface water samples, helping to elucidate pollution hotspots as well as discharge routes.

T1 - EI‐GEO environmental impact of geosynthetics in aquatic systems N2 - EI‐GEO is a multinational research project (Germany, Latvia, Russia) funded under the ERA.Net RUS Plus Call 2017. Aim of the project is the investigation whether geosynthetics in hydraulic engineering applications could be a source of microplastics (MPs) and other contaminants to the aquatic environment causing negative effects to aquatic organisms. Whereas the behavior of geosynthetics in landfill engineering is well studied and documented since decades, little is known on application in applications such as coastal protection or ballast layers for wind energy plants. However, due to the rapid expansion of offshore wind energy, rising water levels and more extreme weather conditions as a result of climate change more and more hydraulic engineering projects will be realized in the future. Applied methods are artificial ageing of geosynthetics in environmental simulation chambers, storage of samples under environmental condition for comparison with laboratory simulation, sample characterization by microscopic methods and ecotoxicological testing of water in contact with geosynthetics. In parallel a case study at the Baltic Sea shore at Kaliningrad Oblast (Russia) will be performed. The aim of study is to estimate the level of pollution of the beaches by geosynthetic debris and identify the possible sources.

In der landwirtschaftlichen Produktion werden dem Boden die Phosphate durch Wachstum und Ernte der Pflanzen entzogen und müssen ihm in Form von Phosphatdüngemitteln wieder zugeführt werden, um die Nahrungsmittelproduktion zu sichern. Rohphosphat stellt die Grundlage unserer derzeitigen Phosphatdüngemittel dar, ist aber gleichzeitig ein endlicher Rohstoff. Des Weiteren sind insbesondere sedimentäre Rohphosphate oftmals mit erheblichen Konzentrationen toxischer Schadstoffe wie Cadmium, Uran und Thorium belastet. Eine Kreislaufführung des Phosphats sollte erfolgen, um natürliche Rohstoffvorkommen zu schonen und den Eintrag von Schadstoffen auf unsere Böden zu unterbinden.
