A. Context One of the objectives of the European Construction Products Directive (CPD) is to harmonize the technical specifications with regard to dangerous substances and construction materials. Construction products could emit or contain dangerous substances that have been defined as dangerous substances under Commission directives and national regulations. In the future construction products may only be placed on the market in the European Union if they accord with the (second generation) harmonized technical specifications including health aspects and bear the CE mark. B. Objectives The goal of this research project is to improve the flow of knowledge and information vis-à-vis normalisation activities in the domain of indoor air measurements, indoor product emission testing, labeling and certification by proposing an evaluation method and standardized assessment methods for a harmonized approach relating to emissions from building materials into indoor air for implementation in Belgium. This approach will comply with current European harmonizing efforts ongoing on European level. C. Conclusions  International tendencies as well as national developments indicate the growing importance of building material emission testing  Harmonisation of governmental schemes to assess volatile organic emissions in the context of the CPD is necessary to obtain transparency  The topic of different limit values in different countries is a difficult problem to solve  It was demonstrated that it is possible with alternative methods (µ-chamber and FLEC) to achieve a qualitative and quantitative correlation with the reference method. However there is a need to extend this comparative study to more materials  The important influence of the quantification procedure on the emission results was demonstrated  The possiblity to investigate microbial resistance of building materials with the so called µ-chamber technique was demonstrated  A twofold methodology for the odour determination of building materials was developed: a quantitative method based on intensity and a qualitative method based on hedonic scale. Furthermore the basis for the development of an electronic nose specific for evaluation of building materials was laid down  A possible evaluation scheme for Belgium on the basis of AFSSET/AgBB/prEN15052 was proposed with two modifications: - Time path modification (7 or 10 days) - Prescreening with alternative method (< 20 L) D. Contribution of the project in a context of scientific support to transfer of knowledge and innovation This research project for implementation of the essential requirement “Hygiene, health and the environment” of the Construction Products Directive has besides its informative and sensitizing role also performed a supporting role in the development of new innovative low emission construction products. The research project has also ensured a Belgian input in the validation work of the draft standard "Emissions into indoor air" - WI 351009 - Construction products - Assessment of emissions of regulated dangerous substances from construction products - Determination of emissions into indoor air” in development in working group 2 of CEN/TC 351. Furthermore this research project has lead to the development of new innovative test methods tailored to the specific needs of construction products. [less ▲]

A methodology based on social participation through the use of resident diaries was applied to evaluate the odour annoyance in the surroundings of an industrial park in Belgium during one year. The studied area covers about 8 km2 and includes13 potential odour emitting facilities. The network involved 44 residents in the survey, among whom 19 were particularly considered for a detailed analysis. The questionnaire aimed at providing an odour rating twice-daily on a 6-level scale together with an odour type. The fact that the response rate corresponding to “no-odour” was high (79%) is particularly discussed. Some tests are proposed to check the plausibility of the answers, the coherence within clusters of residents and the individual performance of respondents to discriminate among odour ratings. The odour rose is presented as an attractive and visual tool, particularly suited in the case of multi-source areas, to map the different odour emissions, to point out the most worrying ones, to identify others creating less annoyance and possibly new unpredicted ones. The resident diary method has proven to be particularly useful, conjointly to other ones, to the case of multi-sources facilities in large areas, when the purpose is the assessment of the long-term evolution of odour annoyance.

La qualité d'un matériau de construction, outre ses caractéristiques physiques, est fonction de son impact sur l'environnement intérieur. Ceci pousse de plus en plus les fabricants à proposer sur le marché des matériaux (dont les "bio-matériaux") dont les émissions atmosphériques demeurent dans des limites acceptables. Plusieurs initiatives, essentiellement volontaires, existent au niveau européen pour évaluer ces émissions. Un des objectifs de la directive européenne des produits de construction (CPD) est d'harmoniser les méthodes d'évaluation. La comparaison de 4 chambres d'émission, de tailles différentes, l'usage de méthodes d'évaluation physico-chimiques couplées à des méthodes sensitives de mesure des odeurs et l'utilisation de la technique des nez électroniques constituent l'originalité de la démarche du projet mené par l'université de Liège en collaboration avec deux autres institutions belges. Plus généralement, le nez électronique représente un outil particulièrement bien adapté au suivi d'ambiances gazeuses au cours du temps. L'odeur émise peut ainsi servir comme "variable de process" pour suivre en continu, voire contrôler, des processus utilisant la bio dégradation de produits, comme le compostage, la bio méthanisation ou le bio séchage.

Worldwide different (mostly voluntary) approaches exist to evaluate emissions from construction products. The importance of the relation between construction products and health & environment is highlighted in the mandatory European Construction Products Directive (CPD). One of the objectives of the European Construction Products Directive (CPD) is to harmonize the technical specifications with regard to dangerous substances and construction materials as stated in the Essential Requirement N°3 “Hygiene, health and the environment” (ER3). The Belgian Building Research Institute (BBRI) is involved in the implementation of ER3 by participation in standardisation work on CEN (CEN/TC 351) and EOTA (EOTA PT9) level. This paper presents first results of ongoing BBRI research activities in collaboration with VITO (Flemish Institute for Technological Research) and ULg (Université de Liège) concerning “horizontal evaluation method for implementation of the CPD (HEMICPD)”: http://www.bbri.be/go/hemicpd.

The e-nose technology has enormous potentialities for in site monitoring of malodors. However a number of limitations are associated with the properties of chemical sensors, the performances of the signal processing and the realistic operation conditions of environmental field. From the experience of the research group in the field, the metal oxide based gas sensors (Figaro type) are until now the best chemical sensors for long term application, more than one year of continuous working in the field. To be usable for malodors measurement in the field, the e-nose has to deal with the lack of long term stability of these sensors. The drift and the sensors replacement have to be considered. In order to appraise the time evolution of the sensors and the effect on the results of an electronic nose, experimentation has been performed during three years on two identical sensor arrays. The two arrays contain the same six Figaro sensors and are in the same sensor chamber of the e-nose system. Both arrays have worked continuously during three years without break. [less ▲]

Artificial olfaction system (the so-called electronic nose) is a very promising tool to monitor the malodour in the field. Usual odour measurement techniques use human olfaction or analytical techniques. The first category represents the real odour perception but is not applicable to measure in continuous bad odours in the field. The second class of techniques gives the composition of the mixture but not the global information representative of the odour perception. The e-nose has the potentialities to combine “the odour perception” and the “monitoring in the field”. However to be able to reach this goal, the signal processing has to be adapted to work in complex environment. We have more than teen years experiments in the measure of environmental malodours in the field and the paper presents the minimal requirements that we consider essential for artificial olfaction system to become successful for this application.

For more than 8 years, an interdisciplinary air survey was achieved by ISSeP around 10 municipal solid waste (MSW) landfills in Wallonia (Belgium). Surveying campaigns include 4 axes of investigations: landfill gas (LFG) surface emissions detection, ambient air quality control, odours annoyance assessment and measurements on exhaust fumes from LFG valorisation units. Especially the first 3 domains closely interact. Monitoring of landfill surface gas-emissions is performed by a simple low-cost method[1]. Portable FID measurements are taken on landfill surface along regular and dense grids. Krigging measured CH4 concentrations furnish continuous maps which localize higher and lower emission zones, assuming that, at a medium observation scale, high fluxes zones create high methane concentrations in the upper part of landfill capping. Air surveying campaigns on each landfill include ambient air quality measurement. During several weeks, 8 tracers parameters are analysed continuously by on site monitoring devices. They are placed near exploitation, downwind or in direction of the nearest neighbours. Measured values are compared to health threshold values. Local wind directions are simultaneously recorded in order to create “pollution roses”. These graphs show, for each sector of wind direction, the mean concentration of a tracer at the measured point when wind comes from the sector. This dual approach allows controlling that air quality remains safe for human health and checking if possible anomalies are produced by the landfill or not. Evaluating the odour annoyance created by a wide, heterogeneous diffuse and multiple sources such as MSW landfills is a difficult challenge. Classical flux chamber method combined with dynamic olfactometry does not allow apprehending the unique perception of an observer created by a so complex odour emitter. An interesting alternative approach, developed by the Environmental Monitoring Research Group, University of Liège, was applied to the wallonian landfills[2]. Field observers first delineate the regions in which odour impact is experienced. Emission rates are then manipulated in a dispersion model until the predicted size of the impact zone matches the one observed in the field, taking into account of measured meteorological conditions. Such back-calculation assesses global odour emission rates. In situ odour campaigns may guide the positioning of air monitoring devices. Inversely, analysing odorous compounds near a neighbour can corroborate its annoyance by analytical evidences. Knowing the intensity and localisation of LFG emissions often help to better understand LFG odour in the neighbourhood, and motivate the placement of H2S sensor at right place, for example. Finally, by combining results from three fields of investigation, one can obtain a really efficient and complete environmental impact study of a landfill on its surrounding ambient air. [less ▲]
