Full textTransfer of soil gas pollutants (Radon, VOC) into buildings can cause significant health risks. However, analytical models used today to estimate health risks associated with these pollutants contain many uncertainties which can lead to poor risk assessment. Initially, the main objective of this thesis is to contribute to the improvement of these models for risk assessment. Secondly, we propose the development of air flow model for passive Sub slab Depressurization Systems (SDS) design used to protect buildings. The improvement of models focused on the inclusion of the main phenomena of convection and diffusion at building/soil interface, taking into account different types of building substructures. The first improvement concerns the assessment of convection phenomenon through the development of analytical models to quantify air flow rates entering through many kinds of building substructures: floating slab, bearing slab, crawl space and basement. Buildings with buried walls and substructures with a sub slab gravel layer are also treated. A methodology taking into account the presence of cracks, holes and singular leakages of the slab is also proposed. The second improvement of the models is the inclusion of coupled transfer of convection and diffusion near foundations. A numerical study allowed a better understanding of the behavior of pollutants at soil / building interface. Based on this understanding, semi-empirical laws for estimating soil gas pollutants entry rate into buildings are proposed. The various models developed have been validated numerically using a CFD model and experimentally with data from the literature when available. The impact of building substructure on pollutant transfer has been highlighted. A first application of the model is illustrated by their integration into a multizone simulation code to study the impact of these transfers on indoor air quality. Finally, the work ends with the development of a model for designing passive sub slab depressurization systems. The design model developed is validated with in situ experimental data. Preliminary applications using this model focused at first on the impact of meteorological conditions (stack effect, wind) on the sub slab system running. At second, the impact of ventilation strategies on sub slab depressurization performance is studied. Thus, we see the potential interest of this model to test the effective running of passive sub slab depressurization systems in given configuration

Full textRisk assessment tools related to transfers of gaseous pollutant from soil to indoor environments present large uncertainties relative to the knowledge of certain parameters, particularly those relating to the soil-building interface: considering the different basement typology, permeability level of floor. These uncertainties lead to an inaccurate evaluation of the impact of gaseous pollutants on indoor air quality.In order to contribute to the improvement of risk assessment models of gaseous pollutants from the soil, thiswork present in a fist part the development of analytical and numerical models. These models have been adapted to consider the different basement, in order to estimate the transfer of gaseous pollutants from the soil to the building. An analogy with heat transfer phenomena between soil and building is used to develop these models.They predict convective airflow transfers between soils and building, for different soil-building interface.There after, the analytical model has been incorporated into an airflow model. This model enables us to study the impact of different types of basement on the entry of pollutants from soil and the indoor air quality.Besides, experimental works have been made to complete the knowledge of concrete air permeability, because of a lack of data. Furthermore, the convective airflows from soil to building have been quantified experimentally.These airflows have been determined in the experimental house ‘MARIA’ installed in the CSTB. Suchquantification constitutes the first experimental database.Finally, the last part of this work shows a one-year follow-up study about the ability of natural SoilDepressurisation System. This study has been carried out to optimize the solutions of buildings protection from the soil gaseous pollutants

Full textPolluted sites and most precisely vapor intrusion represents a potential risk for human health and its environment. Various screening-level and analytical models have been proposed in order to evaluate vapor intrusion and provide assessment tools for exposure risk. However, some in situ investigations show significant differences between predicted and measured indoor concentrations leading eventually to misleading conclusions and inappropriate solution implementations. These uncertainties are mainly associated with a poor characterization of the site, an incomplete modeling of transfer pathways and mechanisms, or by neglecting certain influencing parameters on this transfer. For example, ignoring the lateral source/building separation may serve as possible explanation of the uncertainties presented by the conventional models based on a homogeneous source distribution assumption. The authors agree that lateral migration plays an important role in the attenuation of the indoor concentration. In homogeneous or continuous source scenarios vapors may migrate mainly vertically towards the building. However, lateral source may promote lateral migration to the atmosphere and less into the building generating a greater attenuation of the indoor concentration. In this context, the main objective of this thesis work is to contribute to the improvement of the assessment and management risk tools in order to improve the accuracy of their estimations and increase their range of application. To do this, new vapor intrusion models are developed considering the lateral source/building separation. These models are built on a numerical experimentation and dimensionless analysis based on existing models (semi-empirical models considering a homogeneous source distribution). The combination of these two approaches allows, on the one hand, to maintain the aptitude of the existing models to consider the physical properties of the soil (permeability, diffusion coefficient, …) and the characteristics of the building (type of construction, building depression, volume,…), and on the other hand, to better precise the position of the source in the soil taking into account the influence of the lateral source/building separation in the estimations. From a comparative analysis, the accuracy of these new expressions is verified comparing to the proposed numerical model (CFD), experimental data and existing models in the literature. Finally, the proposed expressions were coupled with a ventilation code (MATHIS-QAI) allowing to better specify indoor characteristics (ventilation system, air permeability of the envelope, volume of the building, …) and estimate indoor air concentration levels as a function of environmental variations (wind speed, outside temperature, …) over time. From a parametric study it was shown that despite the significant impact of the characteristics of the building, the influence of the lateral source/building separation remains predominant on the attenuation of the indoor concentration (attenuation of several orders of magnitude when the source is laterally offset of the building compared to a homogeneous source). However, specifying the characteristics of the building (construction type, ventilation system, air permeability, …) and weather conditions may increase the accuracy of the estimation avoiding the implementation of extreme solutions or insufficient actions

Full textThe malodorous atmospheric pollution results essentially from four gases SO2, H2S, No2 and NH3. To reduce at best these fatal effects on the health and the environment, it is necessary to control continuously the gas emanations closer to the source, That requires adevice enable to detect these polluant gases, easy to use, with reduced size and weight. In this way, we have realized a portable electronic nose, to detect of the four target gases already mentioned. The sensitive part of this prototype is composed of a matrix of six semi conducting metal oxide sensors, offering a good cross sensivity. The electronic nose mimics the human nose, he has to learn to recognize an odour. This learning phase is realised in the laboratoy by introducing in the sensor cell gas mixtures with controlled composition, The sensor response varies with the nature of the gas (reducing or oxidizing) and their own gas sensitivity. The use of analysis and data methods proves that our electronic nose can well discriminate a complex gas mixture and quantify it. Then, we have placed the electronic nose in a real situation, by studying the odour coming from a duck experimental farm. The obtained results showed that this prototype could well detect the variations of the odour level in accordance with the influent parameters. So, we have realized the laboratory and the real site validation of our electronic nose. But the metal oxide sensors present an inconvenient : they have to keep continuously their working temperature (~ 350°C). To prevent this strong energy consumption, we have developed polymer sensors which work at room temperature. The characterization in laboratory showed that they are sensitive to studied target gases. Their responses to H2S have a good stability in short and middle term, allowing to integrate them into the matrix after complete development

Full textTo answer issues concerning the environmental fate and consequences of trace metallic elements (TME), this thesis aims to improve the assessment of bioavailability, transfers and effects of soil TME by studying the accumulation kinetics of cadmium (Cd), lead (Pb) and zinc (Zn) in the snail Helix aspera. The long-term monitoring of internal concentrations provides a picture of TME accumulation and elimination patterns. The development of toxicokinetic models allows obtaining for the first time both in the lab and in the field an estimate of internal fluxes in H. Aspera. The contrasted kinetic between Cd, Pb and Zn underline the importance of both TME and organism intrinsic characteristics. The subcellular fractionation analysis of the TME allows understanding the variability of the accumulation patterns, the depuration strategies and the toxic effects induced on snail growth and reproduction. The TME internal sequestration and their excretion potential determine the steady-state achievement, the level of witch is modulated by the TME assimilation, directly related to the TME behaviour in soil. This steady-state, by reflecting a balance between assimilation and excretion, constitutes a threshold between environmental and toxicological bioavailabilities. Uptake flux can therefore be considered as an indicator of TME bioavailability and as a predictive determinant of sublethal effects. This research should contribute to the development of bioaccumulation guideline, which is always lacking for the risk assessment in terrestrial environment

Full textThe atmospheric pollution related to the VOC still maintains a great interest since these species contribute to the formation of tropospheric ozone, peroxyacetylnitrate and secondary organic aerosols resulting in negative impacts on human health, climate and on the environment. In order to apply efficient control strategies, there is a need to identify the VOC emission sources, to determine their speciation and their contribution to VOC ambient levels. To date, there is a paucity of data regarding the VOC in the Middle East region (MEA) due to a lack of ground-based measurements leading to insufficient evaluation of air pollution in this region. In this work, we report the results of the first study regarding VOC in Lebanon, a developing country in the MEA region. The study is based on two intensive field measurement campaigns within the frame of the Emission and Chemistry of Organic Carbon in the East Mediterranean, Beirut (ECOCEM-Beirut) project conducted during summer 2011 and winter 2012 at a sub-urban site. Over 70 VOC from C2 to C16 have then been measured. First, we provide insights on the factors controlling VOC distribution. Then, VOC source profiles were determined with field measurements close to the main potential emitters. Finally, we identified the VOC factors, based on the sources profiles established previously, and quantified their relative contribution according to the season, by implementing the source receptor model PMF. The major sources were traffic-related emissions (combustion and gasoline evaporation) in winter and in summer. The modeled results showed an agreement with the local emission inventory regarding the load of the on-road mobile source
