Texto completoPolycyclic Aromatic Hydrocarbon (PAH) concentrations are regulated in ambient air because of theirmutagenic and carcinogenic properties. They are largely emitted by combustion processes and may react withmain atmospheric oxidants to form oxygenated (OPAH) and nitrated (NPAH) derivatives, which can be moretoxic than their parent PAHs. In this work, PAH derivatives were studied using the combination of twocomplementary approaches: laboratory reactivity experiments in controlled conditions and field studies, inorder to better understand their source and fate in the atmosphere. Reactivity study of PAHs adsorbed onnatural particles was carried out by exposing ambient particles to atmospheric oxidants (O3, OH and NO2/O3)in appropriate reactors. Large decays of PAH concentrations were observed, benzo[a]pyrene (B[a]P, which isthe only regulated PAH in Europe), appearing as the most reactive. The formation of OPAHs and NPAHs wasshowed. Nevertheless, quantities of both NPAHs and OPAHs formed were not sufficient to explain the totalamount of PAHs that react, highlighting the formation of other compounds, not detected in this work. PAHdegradation may occur in the atmosphere during the transport of air masses or directly on the filter during thesampling. The study of the major degradation processes was performed during field studies, using two highvolume samplers, one being equipped with an ozone scrubber. Even if, results were not enough to clearlyconclude about the relative importance of both degradation processes, the significant formation of some PAHderivatives on the sampling filter was observed. Then, field campaigns were led on different typologies ofsampling sites around Paris. PAH, OPAH and NPAH concentrations were about ten times higher at traffic sitethan at the suburban one. Moreover, for both OPAHs and PAHs, the major compounds were similar at bothsites, in contrary to the case of NPAHs that appeared different. The traffic site appeared strongly influenced byprimary emissions, whereas high amounts of secondary species were quantified at suburban site. Particle sizedistribution of OPAHs and NPAHs showed their strong association to the finest part of aerosols (Dp < 2.5 μm),highlighting the strong interest of this study considering sanitary impacts. Finally, the study of the particle sizedistribution of primary and/or secondary identified compounds, combined with chemical NPAH and OPAHprofiles, allowed to provide indications about the major origin of PAH derivatives in the atmosphere

Texto completoBiofuels and other biomass-derived chemicals are now considered as a vital part of sustainable energy portfolio, where they promise to contribute to our society’s energy security. Despite the undeniable interest presented by these biofuels, their combustion processes are likely to enhance the formation of OPAHs (Oxygenated Polycyclic Aromatic Hydrocarbons) which may eventually contribute to the formation of soot, and may as well profoundly modify its properties. The work carried out in this thesis focused on the identification and quantification of the oxygenated aromatics formed during the combustion of a lignin-based biofuel in flame conditions. Laminar premixed flames of anisole (surrogate model compound for biomass) and hydrocarbon fuel blends (iso-octane and methane) have been investigated using Advanced Gas Chromatography. In this context, we implemented a sample enrichment technique (sample pre-concentration trap) with a set of in situ and ex situ chromatographic analysis (1D GC-MS, 1D GC-SPT-FID and 2D GC-MS) which enabled us to identify a large panel of different oxygenated (~100) aromatics. These results were then used to analyze the fuel decomposition pathways that lead to the formation of OPAHs. Together with identification, this thesis provides a detailed quantitative experimental database in terms of the evolution of the mole fraction with respect to the flame height for several oxygenated and associated non-oxygenated aromatics. Other biofuels like 2,5-DMF and ethanol were also studied and experimental results showed that the different molecular structures of biofuels lead to significant differences in the formation of intermediate species and pollutants. This work also highlights crucial information concerning the amount and the size of soot particles formed in such flames using LII and SMPS. Preliminary results from soot measurements indicate that the soot particle size in these flames is very small (<10 nm)

Texto completoThe transport sector is subject to strict regulations aiming at limiting pollutants emissions. Biofuels have received particular attention as alternative fuel or additive to traditional fuels for remedying two issues: the depletion of fossil resources and emissions of certain pollutants. In this work we studied the impact of blending conventional fuels with synthetic or oxygenated biofuels on the emissions of non-regulated pollutants, namely carbonyl compounds (aldehydes and ketones) and polycyclic aromatic hydrocarbons (PAHs) adsorbed on soot. Firstly, the carbonyl compounds emissions were studied using an internal combustion engine. The carbonyls were collected at the exhaust of a diesel engine running with biofuel blends and analyzed using high performance liquid chromatography. Secondly, the impact of blending the conventional fuel with oxygenated biofuels on soot formation and adsorbed PAHs were studied using a flat flame burner under well stabilized conditions. This work was completed by the study of the kinetics of oxidation of three oxygenated additives in a jet-stirred reactor at atmospheric pressure, over the temperature range 530-1280 K and for different equivalence ratios (0.5-4). The concentration profiles of reactants, products and main stable intermediates were obtained by probe sampling and gas analyses including Fourier transform infrared spectroscopy (FTIR) and gas phase chromatography. These results were then compared to simulated species concentration profiles obtained using oxidation kinetic models available from the literature

Texto completoIn this manuscript, we describe how we have developed the chemistry of aryne atropisomers with an ortho reactive triple bond to the stereogenic axis. These reaction intermediates are easily generated in situ and react in enantiospecific manners, and allow the synthesis of novel atropisomers. In particular, we describe the generation and applications of a synthetic equivalent of a BINOL-derived bis(aryne) atropisomer, as well as the semi-experimental measurement of the reaction barrier of such arynes in the presence of a standard arynophile. At the end of the manuscript, we describe our efforts to develop a synthetic approach to two regioisomers triple helices

Texto completoPolycyclic aromatic hydrocarbons (PAH) are ubiquitus environmental contaminants know to be carcinogenic as well as immunosuppressive. Using as PAH the synthetic compound 7. 12-dimetthylbenz(a)anthracene (DMBA) that is well characterised for its immunotoxicity in mice, we study DMBA interaction with T lymphocyte activation focusing mainly on calcium homeostasis. DMBA induces an increase in intracellular calcium (Ca2+ic) in murine T lymphocytes and also human T lymphocytes. This Ca2+ic elevation is detected early in murine T cells whereas this augmentation is observed later in human T cells. In murine T lymphocytes, DMBA induced calcium elevation follows tyrosine kinase activation and inositol-1,4,5-triphosphate production. This leads to calcium depletion of the endoplasmic reticulum. Furthermore, DMBA also blocks extracellular calcium entry. Thus, reduction of calcium mobilisation by DMBA is responsible to altered T cell proliferation in response to mitogens. In the second part of this study, we have defined the structural requirements for suppression of murine T lymphocyte activation by DMBA using two benz(a)anthracene monomethylated derivatives, 7-methylbenz(a)anthracene (7MBA) and 12-methylbenz(a)anthracene (12MBA). We show that DMBA is the more active for suppressing T cell activation. Like its two derivatives, DMBA inhibits molecular events that lead to G0 toG1 transition of the cell cycle (il-2 production, high affinity il-2 receptor expression). However, only DMBA interferes with G1 to S transition by inhibiting il-2 dependent proliferation. The methyl in position 12 is necessary to modify calcium homeostasis in murine T lymphocytes, since 12 MBA acts in the same way as DMBA unlike 7MBA which does not increase Ca2+ic. Finally, immunosuppression of human peripheral blood lymphocytes and murine splenocytes is compared following DMBA in vitro exposure. NK cytotoxicity, T cell proliferation, cytotoxic T lymphocyte induction and function are affected by DMBA whatever the origin of the cells (human or murine) despite a different mechanism of DMBA with calcium homeostasis in murine and human cells
