abstract = {The oil and gas industry produces large quantities of sour gases. in the perspective of the geological storage of acid gases in deep aquifers, the solubility of co2 + h2s mixtures in pure water and in a 2 m nacl solution was studied under conditions typical of geological storage. phase equilibrium measurements were undertaken at a temperature of 120 °c and pressures ranging from 1.7 to 35 mpa. homogeneous mixtures of co2 + h2s with h2s volume fractions of (0, 1/4, 1/3, 1/2, 2/3 and 1) were placed in contact with solution, and solubility was measured by continuous sampling of the solution. the protocol used was validated by comparison of the results obtained on pure gases with literature data. the mutual interaction between the gases in the mixture has a substantial influence on their respective solubilities. equation-of-state models reproduce the decrease of co2 solubility in the presence of h2s, but underestimate the exclusion of h2s by co2.},

abstract = {This paper provides a detailed study on the sedimentation patterns and the recent morphodynamic evolution affecting the macro-tidal salt marshes located west of the mont-saint-michel (france). twenty-two stations along three transects on the marshes were seasonally monitored for marsh surface level variations from 1999 to 2005, using a sediment erosion bar. the corresponding erosion/accretion rates were obtained together with data on topography, vegetation cover, and grain size of surface sediment. to examine the mechanisms contributing to the salt marsh sedimentation, the data and their evolution were treated with respect to tides, relative mean regional sea level, and wind speed/frequency variations. from 1999 to 2005, the marsh was globally accreting (from 3.45 to 38.11 mm yr−1 in the low marsh, up to 4.91 mm yr−1 in the middle marsh, and up to 1.35 mm yr−1 in the high marsh), while the study was conducted during a window of decreasing trend in mean regional sea level (−2.45 mm yr−1 according to regional-averaged time series). these sedimentation rates are one of the highest recorded worldwide; however, the sedimentation was not found to be continuous over the period in question. this pattern is illustrated by the strong extension of the marshes from 1999 to 2002, and the relative stability observed from 2003 to 2005. the imported and reworked sediments are trapped and fixed by the dense vegetation (puccinellia maritima, halimione portulacoides), inducing the general seaward extension of the marshes. the processes governing sediment budget (accretion/erosion) show annual, seasonal, and spatial variability on the marsh. spatial variations display contrasted patterns of erosion/sedimentation between the low, middle, and high marsh, and between the different transects. these patterns are a result of distance from sediment sources, strong heterogeneity in vegetation cover (human induced or not), and contrasting topographic and micro-topographic characteristics. the higher accretion rates are observed in distal settings in the low marsh, and strongly decrease toward the middle and high marsh. this evolution results from a decrease in accommodation space/water column thickness, and frequency of inundation coupled with an increase in station elevation, but also from the cumulated effects of vegetation cover and micro-topography. the vegetation cover of the low and middle marsh enhance the settling and fixing of fine sediments imported through tides or dispersed by flood and ebb currents. the seasonal evolution of the marshes is marked by contrasting effects of water storage in the sediment. the overall seasonal sediment budget is controlled by the variation of the frequency of inundation relative to tidal range and marshes topography. autumns are influenced by the tide (equinoxes), relative mean regional sea level, and variations in wind speed/frequency. winter wind speed and frequency in relation with tidal variations appear to be the main parameters regulating winter marsh evolution. summers are predominantly under the influence of local variations in water storage (desiccation) while external parameters generally display a low influence. although it is not governed by any one parameter, springtime sediment budget seems to result from strong interaction between the above-cited parameters, despite the significant frequency of inundation (equinoxes).},

abstract = {Studies on two lead and zinc smelters in northern france (metaleurop nord and umicore) showed that the level of metallic contamination of kitchen garden soils is higher than the agricultural soils located in the same environment. this results most particularly from cropping practices and the addition of various products. due to the physical and chemical parameters of these soils, the behaviour and transfer of pollutants towards various plants (grass, trees, and vegetables) may be perceptibly different than what is observed on agricultural soils. for a better understanding of pollutant behaviour in kitchen garden topsoils, the cd, pb and zn was fractionated using the sm&t protocol and various extracting solutions (cacl2, acetic acid, and citric acid) to evaluate their mobility in two highly contaminated soils chosen in the area affected by the past atmospheric emissions of the two smelters. in addition, agricultural topsoil was sampled in a non-massively contaminated area and was therefore chosen as the control soil. the three soils were amended with a mixture of hydroxyapatite (ha) and diammonium phosphate (dap). at 6 months, extracting procedures were carried out to evaluate the effects of the amendment on the mobility of cd, pb and zn. this step was then supplemented by an evaluation of the impact of the amendment on the phytoavailability of pollutants, which was determined in plant uptake studies with ryegrass (lolium perenne l.) by considering only the pollutant concentrations in their shoots. two experiments were carried out. in the first one, unamended and amended soils and ryegrass were watered with distilled water (ph = 7). in the second one, osmosed water (ph = 5.5) was used to evaluate the effects of the acid water–phosphate amendment system on the mobility and phytoavailability of cd, pb and zn. six months after the start of the experiments, the selective extractions showed that the effectiveness of the amendment studied depended on the element, the soil and the water's ph. reductions of metal eluted from the contaminated soils were 1.5–37.9% for cd, and 9.1–80.9% for pb. application of p amendment to the combination of osmosed water was generally the most effective for immobilising cd and pb elution. in contrast, the mixture of ha and dap was ineffective for reducing zn elution. the plant-fresh biomass yield was significantly (p < 0.05) increased by the combination of p amendment and distilled water, whereas a reduction of biomass was recorded with the combined amendment and osmosed water. addition of p amendment generally reduced pb uptake in ryegrass shoots (1–47%), while both cd and zn were increased by 17.9–79% and 0.45–100%, respectively.},

abstract = {Crosslinked polyurethanes based on a mixture of toluene diisocyanate, polypropylene glycol, trimethylol propane (tmp), glycerol (gly), and desmophen (des) were synthesized with various ratios of des and gly. chemical crosslinks were introduced through the hard segment (tmp, gly) and through the soft segment (des). the effects of the degree of crosslinking on the properties were examined. the crystallinity of the obtained polymers were studied by using modulated differential scanning calorimetry, differential scanning calorimetry, dynamic mechanical analysis and their morphology was studied by atomic force microscopy. it appeared that the degree of crosslinking increased according to the increase of gly content. moreover, it was found that chemical crosslinks in the hard segment destroyed the crystallinity of the hard phase and reduced the mobility of the soft phase, improving the heat stability of the hard domains, and modifying the mechanical properties of polyurethane films.},

abstract = {Cement based materials are porous, may contain organic adjuvants, and thus possesses an important primary bioreceptivity. to preserve constructions from fungal colonization and to act efficiently against fungal biodeterioration, it is necessary to have a better understanding of biodeterioration mechanisms and its effects on materials properties. an accelerated laboratory test which allows us to compare the growth of three fungal strains and the aesthetic biodeterioration of a cementitious matrix was developed. as the surface ph of the fresh cement specimen is too high to allow fungal growth (ph ~12), accelerating weathering of the matrix, consisting of the combination of carbonation and leaching, was performed to reduce the matrix alkalinity. xrd analyses and sem observations pointed out that the matrix surface is progressively covered by a calcium carbonate layer as the weathering increases. results point out that the microbial growth occurs on matrix with a surface composition more like a limestone than a cementitious one.},

abstract = {Les activités du laboratoire sols et environnement de l’institut portent sur cinq thématiques. connaître les paramètres physicochimiques des sols régionaux, c'est-à-dire élaborer les bases de données qui renseignent sur ces paramètres des sols. diagnostiquer leur degré de contamination, principalement en éléments métalliques. etudier le comportement de ces polluants dans les sols. contribuer à l’évaluation de l’exposition aux polluants des populations. proposer et évaluer des techniques de remédiation de sols fortement contaminés, principalement en utilisant une végétation, qu’elle soit arborée ou herbacée. l’équipe pluridisciplinaire est constituée de 14 personnes, 7 enseignants chercheurs, 1 ingénieur recherche, 1 ingénieur d’étude, et trois doctorants et post-doctorant. l’intérêt de nos travaux, c’est qu’ils sont menés dans le cadre d’un vaste partenariat universitaire, institutionnel et industriel, et nous avons beaucoup profité du programme de recherche présenté par jean-marie haguenoer qui nous a permis notamment d’accéder à un site atelier exceptionnel. l’impact de la pollution sur l’environnement est une question extrêmement complexe à plusieurs titres. il s’agit de polluants d’origine et de nature très diverses, regroupés en deux grandes catégories : polluants organiques et polluants inorganiques. ils concernent divers compartiments environnementaux : l’eau, l’air, le sol, les poussières, la biosphère, les plantes, les animaux. on est souvent en présence des pollutions des sols à des degrés très variables, mais également multiples, c'est-à-dire combinant à la fois des polluants métalliques et/ou inorganiques. leurs comportements diffèrent selon leur nature, leur degré de contamination et leur forme chimique. enfin, des dangers environnementaux et sanitaires sont très variables et plus ou moins connus selon la concentration et la nature des polluants.},

abstract = {Field investigations were conducted to measure subsoil trace element content and factors influencing content in an intensive periurban market garden in chenggong county, yunnan province, south-west china. the area was divided into three different geomorphological units: specifically, mountain (m), transition (t) and lacustrine (l). mean trace element content in subsoil were determined for pb (58.2 mg/kg), cd (0.89 mg/kg), cu (129.2 mg/kg), and zn (97.0 mg/kg). strong significant relationships between trace element content in topsoil and subsoil were observed. both pb and zn were accumulated in topsoil (rts (ratio of mean trace element in topsoil to subsoil) of pb and zn >= 1.0) and cd and cu in subsoil (rts of cd and cu <= 1.0). subsoil trace element content was related to relief, stoniness, soil color, clay content, and cation exchange capacity. except for 7.5 yr (yellow-red) color, trace element content increased with color intensity from brown to reddish brown. significant positive relationships were observed between fe content and that of pb and cu. trace element content in mountain unit subsoil was higher than in transition and lacustrine units (m > t > l), except for cu (t > m > l). mean trace element content in calcareous subsoil was higher than in sandstone and shale. mean trace element content in clay texture subsoil was higher than in sandy and sandy loam subsoil, and higher cu and zn content in subsoil with few mottles. it is possible to model pb, cd, cu, and zn distribution in subsoil physico-chemical characteristics to help improve agricultural practice.},
