T1 - Auswirkungen der novellierten AbfKlärV auf die Kreislaufführung von Pflanzennährstoffen N2 - Die landwirtschaftliche Klärschlammverwertung ist in der Bundesrepublik Deutschland seit Jahren rückläufig. Neben den Risiken durch Schadstoffeinträge gibt es in Deutschland Regionen mit einem stark erhöhten Nährstoffüberschuss. Um die Grundwasserbelastung zu verhindern wurde u.a. das Düngerecht verschärft, was die Flächenkonkurrenz zwischen Klärschlamm und Wirtschaftsdünger vergrößern wird. Es ist davon auszugehen, dass sich die neuen Regelungen im Düngerecht und der Klärschlammverordnung massiv auf die landwirtschaftliche Verwertung von Klärschlamm und damit auf die Kreislaufwirtschaft verschiedener Nährstoffe auswirken werden. In diesem Beitrag werden erste Ergebnisse des Projekts extraWERT vorgestellt.

T1 - Braune Tinten – Geschichte und Materialität N2 - Eine Vielzahl unterschiedlicher Materialien findet für die Gestaltung von Zeichnungen Verwendung. So sind es insbesondere „braune Tinten“, welche die Zeichnungen dominieren. Der Vortrag möchte zunächst einen kurzen Überblick über die Terminologie und die Kunsttechnologie farbiger Tinten geben, um den Kosmos dieser Vielfältigkeit und auch deren Vergänglichkeit zu illustrieren. Der zweite Teil des Vortrags ist dann den sogenannten Bistertinten und deren analytischen Nachweisen gewidmet. Es handelt sich um Zeichentinten, die aus den wasserlöslichen Bestandteilen von Kaminruß gewonnen werden. Die farbliche Bandbreite reicht von gelb-orange bis braun. Zuweilen wurden diese Tinten mit weiteren Pigmenten versetzt, um eine bestimmte Farbtiefe zu erzielen. T2 - 29.

T1 - Chinese paper in Persian manuscript: Preliminary results of a of a codicological, technological and scientific study N2 - In the 15th century, Persian manuscripts underwent significant and lasting changes. Possibly as a response to the import of tinted and gold-decorated paper from China, which was used for manuscript production in Greater Iran, Persian papers were also tinted and embellished with gold-decorated and marbled margins or frames. In a joint project between CSMC and the University of St Andrews, we aim to analyse papers and their decorations in Persian The analyses aim to determine the consistencies of papers, pigments and metals and the techniques used for their production and application. The support will be first described in its codicological characteristics such as dimensions, thickness, colour (expressed in colour coordinates), pattern left from the sieve (observed in transmitted light). The plant used as raw material in paper production will be studied by fibres analysis, while the sizing agents, the pigments, dyes and metals will be analysed by the application of several methods: in particular Reflectography, X-Ray Fluorescence and InfraRed, Raman and Visible Reflectance Spectroscopy. The results of the analyses will form an important resource for the material aspects of Persian manuscripts and be a starting point for establishing a first chronology of the materials and techniques used in Persian manuscript production. An example of the application of the techniques on the analysis of a fragment from a 15th c. Persian Manuscript will be provided.

T1 - CRMs for (semi-)VOCs in sorbent tubes N2 - EN 16516 sets the test method and requirements for the determination of emissions of Volatile Organic Compounds (VOCs) from building materials into indoor air. To address the quality control requirements for the class of semi-VOCs (SVOCs), VSL developed gaseous reference materials. A novel home-made dynamic gas mixture preparation system, operating according to ISO 6145-4 (continuous injection method), has recently been developed and validated. Thanks to the stable temperature control up to 100 oC, the system can prevent condensation of the SVOCs in air at indoor air concentration levels. The in-situ obtained SVOC gas standards can be sampled in sorbent tubes to obtain SVOC transfer standards. A study was performed to determine the optimal sorbent material and storage conditions. This study will be presented together with the results of the 2018 Round Robin test for emission test chamber measurements organised by BAM. Using the novel system, VSL prepared transfer standards with known amounts of VOCs and SVOCs for participants to evaluate their analytical performance.

However, methanogenic Archaea (MA) can also be highly corrosive by using iron as an electron source for methanogenesis. Because of the fundamental physiological differences between archaea and bacteria, responses of MA towards SRM-specific biocides cannot be deduced using SRM. Due to the lack of information available on the effect of biocides on corrosive MA, we selected THPS, glutaraldehyde, nitrate and perchlorate to compare against corrosive SRM. Preliminary results showed that at low concentrations of THPS (0-10 ppm), growth of MA was not affected, methane production and corrosion rates (0.1 mm/yr) were comparable between the different THPS concentrations. On the contrary, the SRM strain showed decreased corrosion rates (0.18 mm/yr to 0.03 mm/yr) with increasing THPS concentrations. Further corrosion tests including electrochemical measurements of different biocides on the growth of MA and SRM will be conducted. Such knowledge not only provide important insights on the physiological response of MA to biocides but also contribute to more effective mitigation strategies that can be both economic and environmentally beneficial.
