A1 - Philipp, Rosemarie T1 - An interlaboratory comparison on whole water samples N2 - The European Water Framework Directive 2000/60/EC requires monitoring of organic priority pollutants in so-called whole water samples, i.e. in aqueous nonfiltered samples that contain natural colloidal and suspended particulate matter. Colloids and suspended particles in the liquid phase constitute a challenge for sample homogeneity and stability. Within the joint research project ENV08 ‘‘Traceable measurements for monitoring critical pollutants under the European Water Framework Directive 2000/60/EC’’, whole water test materials were developed by spiking defined amounts of aqueous slurries of ultrafinely milled contaminated soil or sediment and aqueous solutions of humic acid into a natural mineral water matrix. This paper presents the results of an European-wide interlaboratory comparison (ILC) using this type of test materials. Target analytes were tributyltin, polybrominated diphenyl ethers and polycyclic aromatic hydrocarbons in the ng/L concentration range. Results of the ILC indicate that the produced materials are sufficiently homogeneous and stable to serve as samples for, e.g. proficiency testing or method validation. To our knowledge, this is the first time that ready-to-use water materials with a defined amount of suspended particulate and colloidal matter have been applied as test samples in an interlaboratory exercise. These samples meet the requirements of the European Water Framework Directive. Previous proficiency testing schemes mainly employed filtered water samples fortified with a spike of the target analyte in a water-miscible organic solvent.

Sie geht davon aus, dass es ressourcenschonendere Lösungsansätze gibt, die nicht nur die Anforderungen an die oben aufgeführten Aspekte erfüllen, sondern auch zu einer ganzheitlich verbesserten Wohngesundheit beitragen. Es soll nachgewiesen werden, dass sich durch den Einsatz von emissionsarmen, klimasteuernden Naturbaustoffen in Verbindung mit einer dampfdiffusionsoffenen Gebäudehülle und einem angemessenen Glasanteil, eine stabile Raumluftfeuchte und ein gesundes Raumklima in Wohngebäuden einstellen lässt.

T1 - Towards tributyltin quantification in natural water at the Environmental Quality Standard level required by the Water Framework Directive N2 - The European Union (EU) has included tributyltin (TBT) and its compounds in the list of priority water pollutants. Quality standards demanded by the EU Water Framework Directive (WFD) require determination of TBT at so low concentration level that chemical analysis is still difficult and further research is needed to improve the sensitivity, the accuracy and the precision of existing methodologies. Within the frame of a joint research project “Traceable measurements for monitoring critical pollutants under the European Water Framework Directive” in the European Metrology Research Programme (EMRP), four metrological and designated institutes have developed a primary method to quantify TBT in natural water using liquid–liquid extraction (LLE) and species-specific isotope dilution mass spectrometry (SSIDMS). The procedure has been validated at the Environmental Quality Standard (EQS) level (0.2 ng L−1 as cation) and at the WFD-required limit of quantification (LOQ) (0.06 ng L−1 as cation). The LOQ of the methodology was 0.06 ng L−1 and the average measurement uncertainty at the LOQ was 36%, which agreed with WFD requirements. The analytical difficulties of the method, namely the presence of TBT in blanks and the sources of measurement uncertainties, as well as the interlaboratory comparison results are discussed in detail.

T1 - Hygroscopic natural materials versus mechanical ventilation N2 - Multi residential buildings, developed as highly energy-efficient and airtight are nowadays often fitted with mechanical Ventilation Systems as a way to overcome shortcomings and even defects tinked to indoor climate. The presented study investigates the potential of low-emitting. natural building materials with hygroscopic properties to contribute to a healthy and comfortable indoor environment, while reducing the need for mechanical Ventilation. A selection of natural building materials suitable for application as internal partition walls has been investigated with regards to their water vapour adsorption capacity. Special emphasis was placed on the investigation of modified earth plasters as well as wood-based materials, used as wall lining to provide increased adsorption capacities. In addition, tests on materials emissions (formaldehyde, VOCs, SVOCs and radon) as well as adsorption tests of airborne pollutants have been conducted in specially-designed fest chambers. All tests were performed at either the material or the component tevel. Overall results to date suggest that natural materials contribute to an improved indoor environment quality through an increased moisture-buffering capacity, low emissions and the potential to adsorb airborne pollutants, therefore reducing the need for mechanical Ventilation.

Der Gebäudesektor und damit auch die Architektur verbrauchen in Deutschland ca. 50 % der fossilen Energieressourcen und verursachen ca. 60 % des gesamten Müllaufkommens mit dem zugehörigen Bedarf an Ressourcen in der Errichtung. Öl, Stahl und Beton haben uns Glauben gemacht die natürlichen Begebenheiten bei der Gestaltung von Gebäuden wenig beachten zu müssen. Immer neue Techniken zum Betrieb und zur Klimatisierung von Gebäuden waren die Zukunft. Der Klimawandel und die Ressourcenknappheit sind Aufforderungen zur Veränderung. Das Voranschreiten der Reform des Bauwesens hat somit zentrale Bedeutung zur Erreichung der Nachhaltigkeitsziele und um unsere Gesellschaft zukunftsfähig zu machen. Klimaangepasste Architekturkonzepte und die Verwendung von klimaaktiven Naturbaustoffen werden einen wesentlichen Beitrag zum Ressourcenschutz erbringen. N2 - More resources are consumed for the construction and use of buildings and dwellings than in any other industry. The building sector, and by extension architecture, is responsible for consuming around 50 % of fossil fuels in Germany and produces around 60 % of the entire volume of waste together with the resources used for the construction of buildings. Oil, steel and concrete has led us to believe that we can overcome the laws of nature in the design of our buildings, and for years we have devised ever new technologies for controlling building climate and operating our buildings. But the onset of climate change and the continuing depletion of resources signals a need for Change. To achieve our declared sustainability goals, and to better equip society for the future, it is vital that we effect reforms in the building sector. Climate-adaptive architectural concepts and the use of climateresponsive natural building materials can potentially make a major contribution to conserving resources. T2 - Lehm 2016 - 7.

T1 - Naturally ventilated earth timber constructions N2 - Earth, timber, fibre boards and insulation materials based on wooden and other natural fibres offer a variety of properties beneficial for eco innovative constructions that are able to improve the energy and resource efficiency of buildings. Due to their porosity, natural building materials are vapour active and are able to buffer moisture. In combination with highly insulated and airtight but vapour permeable building envelopes, modern earth-timber constructions provide stable indoor humidity levels and can therefore be naturally ventilated while achieving highest energy efficiency standards. Experimental evidence suggests that monitored pilot buildings in Berlin do show healthy indoor air humidity levels (around 50%) in wintertime, while mechanically ventilated buildings demonstrate significantly lower values (around 25%), which have to be considered as uncomfortable and unhealthy. The application of building materials being poor in chemical emissions, particularly volatile organic compounds (VOC) and radon, improves the indoor air quality further, so that intermittent ventilation twice a day will be sufficient to provide healthy indoor air quality. The air quality in critical rooms (e.g. small bedrooms), demonstrating a smaller air volume, should be monitored if appropriate ratios of room size to occupancy level cannot be realised. Through night time ventilation in summer, vapour active earth-timber constructions provide evaporative cooling (humidity adsorption at night time and desorption during the day). As a result, indoor temperatures of earth-timber buildings range around 8 °C below the outside temperature peak, when an appropriate glazing ratio is reflected. The EU funded research project H-house is investigating various construction materials regarding water vapour adsorption as well as emission and absorption of harmful substances. Based on this investigation new wall constructions are designed to provide a healthier indoor environment.

T1 - Determination of 22 trace elements in high-purity copper including Se and Te by ETV-ICP OES using SF6, NF3, CF4 and H2 as chemical modifiers N2 - In supplementary work to the one published earlier, experiments with SF6, NF3, CF4 and H2 as new modifier gases for the matrix studied were performed. Our investigations were continued to improve the described analytical method and to achieve additional insights into the mechanism of analyte release. Our new survey is split in two parts. At first fluorinating modifiers were used to investigate the behaviour of a variety of trace elements (Ag, Al, As, Au, Bi, Cd, Co, Cr, Fe, Mg, Mn, Ni, P, Pb, Sb, Se, Si, Sn, Te, Ti, Zn and Zr). Most of them (exceptions Au, Se, and Te) could be effectively released from the copper matrix by thermo-halogenation reactions and by partial sub-sample evaporation. Using SF6 and NF3 as modifier gases, low limits of quantification (LOQs) were achieved for the 19 well released trace elements (typical ≤0.1 mg kg-1). Most elements (exceptions Ag, Mg, and Ni) could be calibrated by using aqueous calibration solutions without any sample pretreatment. For the trace determination of Se, Te, and Au, a further analytical method of ETV-ICP OES is described in the second part based on thermo-hydrogenation reactions by using a hydrogen/argon mixture as a modifier gas. The determination of Se and Te with very high analytical performance (LOQ < 0.1 mg kg-1) can either be carried out in a second analytical step succeeding the halogenation procedure, or the sub-sample is directly treated with H2 without previous halogenation procedure whereby the sub-sample can either be partially or totally evaporated. In this case some other analytes (Ag, Au, As, Bi, Cd, Fe, Mg, Ni, Pb, Sb, Sn, and Zn) can additionally be quantified simultaneously with Se and Te.
