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 study is conducted in the frame of a programme of monitoring of all landfill sites in Wallonia. The "odour" part is assigned to ULg. The present report concerns more particularly a second campaign on the site of Habay, which is more than a simple landfill area, as it includes also other waste treatment facilities, such as composting and biodrying. Besides the usual field inspection technique, the research group has applied the electronic nose methodology to monitor the odour in the vicinity of the sources and a survey in the surroundings to try to validate the different results.

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 ▲]

This paper presents different methods to assess the odour emission and the odour annoyance in the surroundings. It is shown, on the example of landfill areas and composting facilities, that chemical analyses are helpful to identify key compounds of the odour release, and to set up the specification of a monitoring instrument. Sensitive methods, like dynamic olfactometry or sniffing team investigation, are mainly applicable to provide a global odour plume or an average annoyance zone. And the electronic nose can supply a warning signal to the plant manager or a real time estimation of the annoyance zone. [less ▲]

A specific formula to calculate separation distance from piggeries and poultry facilities to sensitive receptor is developed for Walloon Region, in Belgium. The paper briefly presents the main principles of the formula and discusses more deeply the compatibility of the distance approach with odour units, odour rate and percentiles usually applied to assess the odour annoyance zones. A method of validation is presented and tested to adjust the different parameters of the formula to Belgian field reality. A total of 43 farms of which 21 piggeries and 22 poultry facilities are visited and, for each case, the distance calculated by the formula is compared to the one deduced from odour annoyance criterion (10 ou m-3 at 98th percentile). Validation work results in discussing the sensibility of different factors of the formula and especially in adjusting a fitting factor to match the absolute distances to real field annoyance impression. Conclusions show that both approaches - separation distance formula and percentile evaluation - are coherent. The validation method allows parameter adjustment but should need further refinements to examine separately piggeries and poultry facilities. [less ▲]
