Texto completoThis study can increase knowledge about the travelers' exposure to air pollution inside buses through measures based representative of rolling stock (Agora Long, Agora Standard), the air change rate, air outdoor quality and traffic parameters. The experiments were performed by studying the distribution of pollutants in the cabin, a subject little discussed in the literature. Some sources of pollution such as the material emissions and the transfer of bus exhaust in the cabin are quantified (self-pollution). As part of this approach, an unprecedented campaign was conducted to quantify the maximum and minimum self-pollution for both types of bus. In real traffic conditions, the pollutant concentrations (NO2, PM2.5, particle number concentration between 0.02-1µm) are higher in the instrumented buses compared to outdoors. Moreover the lowest concentrations of NO2 have been measured in the front of the cabin compared to the rear, the localization of exhaust pipe and the engine. This overexposure was explained by a self-pollution higher in the rear of the cabin compared to the front (0.13% against 0.05% in adverse conditions). Finally the influence of the material emissions, traffic, door openings, the wind speed on the pollutant concentrations inside buses have been demonstrated

Texto completoPolluted 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

Texto completoExposure to indoor air pollution is a major health hazard for the general population, leading to respiratory and cardiovascular diseases and even to premature death. In spite of an increasing number of studies in the last decades, indoor air pollution data are still scarce. This is due in part to the many different environments, public or private, to be investigated, and to the availability of instruments that can be deployed in such environments without disturbing the occupants. For these reasons, the now commercially available low-cost chemical sensors are promising instruments for the study of IAQ, provided they are well characterized.In the present work, sensor nodes developed in a multidisciplinary project within the University of Lille, were tested in laboratory semi-controlled conditions to assess their performances and limitations. They were found adequate to quantify with a high time resolution (30 seconds) the concentrations of CO2, CO, NOx, O3, VOC and PM, in spite of some calibration issues linked to chemical interferences and to the dependence of the sensors response on the relative humidity.These sensors nodes were deployed in various residential and non-residential buildings in the metropolitan area of Lille. These measurements showed that, most of the time, the indoor air pollutants concentrations are below the threshold values recommended by the scientific community. The measurements also allowed, when coupled to space-time-activity logs filled by the occupants, to identify and characterize the events leading to concentrations in excess of the recommended values. Such IAQ determinants include cooking, even on electric stove, combustion processes such as cigarette smoking or burning candles or incense, use of body care and housecleaning products, and even the mere presence of occupants.The sensors data were used to calculate a quasi-real time indoor air quality index, based on the INT’AIR® index. This modified index converges quickly with INT’AIR®, therefore allowing to perform an easy and cheap assessment of IAQ as mandated by regulatory instances. At the same time, the new index also responds immediately to pollution events, which could be used by building managers to take actions to improve IAQ when necessary

Texto completoIndoor air quality is of increasing concern in urban societies. Among indoor air pollutants, volatile organic compounds are predominant. These molecules can be degraded by several technologies among which heterogeneous photocatalysis appears to be well-adapted to the. Specificities of indoor pollution. However, the development of photocatalysis for this application will be possible only if two scientific key points are solved: better understanding of reaction mechanisms and possibility to write kinetic laws allowing the scaling up of the process in real condition. With these objectives, the present study deals with the photocatalytic degradation of three model pollutants (acetone, toluene and heptanes) using a fibrous media developed by Saint-Gobain. First of all, this media is characterized in terms of adsorption capacities using a specifically developed model and porosity. Secondly, a dynamic 420L-reactor is implemented to optimize the pollutants degradation according to several parameters (UV Wavelength, light intensity, air velocity at the media inlet, pollutants concentration and molecular structure). To do so, the experimental designs methodology is used. At the same time, a study concerning the formation of reaction intermediates is conducted. Finally, a reaction mechanism is proposed and kinetic laws are deduced. The latter can be integrated in numerical simulations for the design and the efficiency prediction of the process applied to the purification od indoor air

Texto completoThe general objective of this work is to develop a deep understanding of the interaction of the CO with anodic catalysts in PEM Fuel Cells (PEMFCs), and to evaluate its impact on the reactivity towards the hydrogen oxidation and their stability. Firstly, a multiscale kinetic model is built up based on Monte Carlo simulation and kinetic modelling of elementary electrochemical/chemical steps as a tool to simulate the performance of PEMFCs fed with H2 containing CO traces. Experiments on CO adsorption and oxidation mimicking O2 bleeding were used to better understand the mechanisms. Monometallic Pt and bimetallic PtxCoy and PtRu catalysts supported on high surface area carbon were studied. CO adsorption and oxidation were investigated by means of DRIFT spectroscopy and QMS analysis. Defect sites (kink, edge), history of interaction with different gases (H2, O2, CO), temperature, Pt loading, particle size, alloying with Co or Ru are key parameters influencing the CO reactivity with O2. The multiscale kinetic model was applied to Pt and PtxCoy. PtxCoy nanocatalysts are shown to be highly CO tolerant but might degrade by Co dissolution in long term operation, depending on the Pt to Co ratio

Texto completoDuring this thesis, we chemically characterized (metals, EC, OC) then studied the sources and the fate of airborne particles (PM10, PM2,5, PM1) in indoor air. Another part of this work concerns the modelization of their behavior in class-rooms of primary schools in the Nord Pas de Calais region. These PM10 values largely and almost systematically exceed (average value for eight schools: 97 ± 28μg/m3) the daily limit values (50μg/m3) for indoor air (WHO and ANSES recommendations). The only elements Al, Ba, Ca and Fe clearly associated to an indoor source are linked to the use of chalk. Although there is a significant amount of particles of outdoor origins found in class-rooms (such as traffic, industrial or natural sources), pupils’ physical activities represent the major source of airborne PM10 in indoor air. The resuspension phenomenon doesn’t influence significantly the elemental (major and traces elements) distribution of the indoor PM10.The modelization of the evolution of indoor PM10 is clearly influenced by the activities of the pupils in class-rooms, requiring taking into account the resuspension phenomena. In addition, the behavior of particles is associated to their size distribution as well as the intrinsic characteristics of the building envelope which control the indoor-outdoor air exchange.The deterministic model developed in this work will allow easily simulating the evolution of particle concentrations according to their size distribution in class-rooms
