Amutova, Farida. "Assessment of bioavailability of organochlorine pesticides in chain «soil – farm animals – food products»". Electronic Thesis or Diss., Université de Lorraine, 2022. http://www.theses.fr/2022LORR0126.
Soil could be the main vector for the transfer of persistent organic pollutants (POPs) to agricultural animals, and, accordingly, to the food products they produce (meat, milk, eggs). Farm animals especially free-range species could ingest soil in different proportions together with vegetation which in case of contamination context represent a serious consequence to produce insecure food of animal origin. Hereby, this study was mainly focused on sequestration strategies which could ensure the safety of food produced by livestock animals in POP contaminated areas.The current work was focused on organochlorinated pesticides (OCPs) among the POPs. These forbidden and obsolete chemicals have been stored over long time in facilities, which may have been deteriorated over the decades, which raises issues by their diffusion in the environment in various countries. The aim of the current study was to reduce OCPs transfer in the food chain «soil - farm animals - food products of animal origin» by the application of different carbonaceous materials based on activated carbons (AC) or biochars (BC), which are serious candidates to sequestrate POPs. The use AC/BC as soil amendment can adsorb POPs reducing its environmental availability but also their bioavailability for free-ranged animals, which may ingest soil and by consequence soil-bound pollutants.Several scientific concepts such as environmental availability, bioavailability, transfer rate, bioaccumulation factor, adsorption kinetics and adsorption isotherms were integrated into the current study using in vitro and in vivo approaches in order to investigate application of sequestration strategies based on ACs and BCs as possible solutions for reduction of the OCPs (DDT and metabolites, HCH isomers and CLD) transfer from soil to food products in contaminated areas. Several ACs (DARCO, ORBO, Shubarkol) and BCs (Japanese knotweed, Oak tree, Sargassum) were revealed by the current work as effective sequestrants that could be effectively used in sequestration strategies as soil amendment. In addition, physical and chemical properties of SMs, amendment rate, contact time between contaminants and SMs and fractions of soil organic matter appeared as factors explaining efficiency of sequestration strategies based on AC/BCs.Finally, sequestration strategy based on AC/BC can be especially effective under conditions of moderate soil contaminations, which could significantly reduce environmental availability of pollutants (up to 90%) and, as a result, transfer to food products.Keywords: Organochlorine pesticides, Soil, Transfer, Farm animals, Sequestration, Activated carbon, Biochar, Bioavailability
Matta, Roger. "Oxydation chimique in situ de polluants organiques : application aux nitro-aromatiques et aux organochlorés". Aix-Marseille 1, 2009. http://www.theses.fr/2009AIX11010.
This memory deals with the chemical oxidation of organic pollutants within the general framework of soil remediation. The chemical oxidation of three organic pollutants belonging to two different families (organochlorines and nitroaromatics) by: hydrogen peroxide (Fenton’s reaction and modified Fenton), persulfate (activated or not) and permanganate were studied. The oxidation of PCP, TCE and TNT by hydrogen peroxide and iron containing minerals (heterogeneous Fenton) proved to be applicable tat pH 7 and the activity of iron oxides (in particular magnetite) is preserved when incorporated into mineral assemblages with silicates or clay. These results indicate that the presence of the soil endogenous iron could be exploited for ISCO treatment process. The yields of oxidation with a pH close to neutrality increase in the presence of iron chelating agents like EDTA and CMCD. Persulfate was able to oxidize the PCP and the TCE without any chemical activation whereas it did not show any effect on the transformation of TNT. The iron minerals (goethite and magnetite) did not show any reactivity with respect to persulfate. However, the effectiveness of oxidation was increased by the activation of persulfate with EDTA iron chelates. Permanganate was able to oxidize PCP with a higher rate than that of TCE. However the effectiveness of the oxidation of TNT is much lower. A degradation pathway of PCP was proposed for the first time. The results obtained in column confirmed those obtained in batch and showed the feasibility of chemical oxidation under conditions similar to those found at field. For further research concerning the application of ISCO, pemanganate is the oxidant of choice for the organochlorine compounds and heterogeneous Fenton for the nitroaromatics

Source zones formed by chlorinated organic compounds in soils (DNAPL) can contaminate aquifers for several centuries by feeding a plume of dissolved compounds. To deplete those source zones, DNAPL pumping is the simplest option, but the efficacy is limited by preferential water flow in the soil and capillary forces that are trapping the DNAPL. More aggressive strategies (dissolution, thermal treatment, chemical degradation...) are also costlier. Within this thesis work, two treatment strategies using surfactant foam were developed and assessed at lab-scale to prepare field assessment. The first strategy relies on foam injection in the source zone to mobilize the DNAPL in a controlled fashion to drive it ahead to pumping wells. In the best conditions, DNAPL saturation was lowered below 1% after treatment with a surfactant consumption below 10 g kg-1 of DNAPL removed. The second strategy uses foam as a reagent (hydrogen) carrier to accelerate the biodegradation of dissolved compounds in the plume. When injected as a foam, hydrogen was delivered in a targeted and more persistent manner in the strata to be treated. Developed technologies showed to be promising at field-scale and when the technico-economic assessment was conducted. Research still remains to be done to make those techniques more predictable during their implementation

In a first step, we have tried to prepare dry or humidified mixtures composed with clays or real soils homogeneously spiked by organochlorine pollutants (Pyralène Tl, chlorophenols). Beyond the homogeneity aspect, we wanted to know if the preparation procedure allow to obtain pollutant adsorption on the absorbent. Finally we propose a protocol (with a rotary evaporator) satisfying the homogeneity critter. However, we observe some pollutant losses and we show that, for dry mixtures, the pollutant is not adsorbed but only coats soil particles. We demonstrate the water effect on adsorption. In a second step, with these synthetic mixtures, we compared the efficiency of four types of extraction techniques: thermal way (micro sublimation, thermal desorption, pyro-injection), by liquid organic solvents (Soxhlet, Soxtec), by carbon dioxide (liquid, gas or supercritical) and by water leaching (at various temperature and pression conditions). Good recoveries are found with techniques using temperature and/or pressure (micro-sublimation) an and an solvent (water, carbon dioxide or organic solvent). As well as adsorption, water influences desorption quality

Understanding of phosphorus (P) forms dynamics and changes in agro-ecosystems is essential for the development of best management practices to maintain soil productivity and surface water quality. The objective of this thesis was to develop and use innovative methods to characterize soil P forms and their changes under different management practices. We examined the potential of near infrared spectroscopy (NIRS) to predict soil total P (TP), soil P extracted by Mehlich-3 solution (M3P) and by water (Cp), and soil organic P (OP) for soil samples taken from two sites with different P content located at Quebec and Saskatchewan. The results showed that the prediction of TP and M3P in the site of Quebec were moderately useful and not acceptable, respectively. However, the opposite was found in the site of Saskatchewan. The prediction of OP was moderately useful to moderately successful in experimental site of Saskatchewan. The potential of NIRS to predict P depends to the soil texture, to P soil content variation and to the relation of P to organic matter. Furthermore, contradictory results of variance and correlations analyses were found for the raw and ordinary log transformed molecular P species expressed as proportions or concentrations, indicating spurious correlations. Using compositional analysis with centred log ratio or isometric log ratio transformations avoid the methodological biases and allow coherent interpretation. Finally, phosphorus-31 nuclear magnetic resonance spectroscopy was used to characterize P species for soil samples collected from a long-term corn-soybean rotation experiment in Quebec. Results showed an accumulation of TP (1326 mg kg-1) on the top 5 cm of P fertilized soil under no-till primarily due to orthophosphate ions accumulation (49.7% of TP). However, the organic P forms of inositol monoesters and nucleotides had accumulated in the deep layer; indicating a potential loss through different hydrological pathways. Overall, these studies allow us to improve our understanding of P forms and to better monitor them under different agro-ecosystems using the best management practices.

Le polluant considéré est le trichloréthylène, le milieu poreux est un sable moyen et les expériences ont été réalisées en colonne.
Après la mise au point d'une méthode d'analyse du TCE aqueux, gazeux et sorbé, les mécanismes prédominants des transferts ont été quantifiés isolement essentiellement par le biais d'essais de diffusion en sable sec, à saturation résiduelle en eau et saturé. Puis, ces mécanismes ont été couplés au sein d'une expérience de transfert de TCE en sable avec un profil de teneur en eau réel (hydrostatique). Chaque type d'essai a été dimensionné, si possible dupliqué et interprété grâce au code multiphasique Comsol dont l'équation de l'écoulement a été modifiée afin de considérer la convection gravitaire.
En contrôlant rigoureusement les facteurs externes influents ainsi que les conditions aux limites, il a été possible de réaliser des expériences reproductibles et interprétables de transfert de TCE, un composé volatil et réactif en milieu poreux très perméable. Une bonne reproductibilité des résultats expérimentaux par la simulation a été obtenue moyennant de légères modifications des paramètres de base : rapport perméabilité sur viscosité, tortuosité(Millington, 1959) et paramètre de calage de la courbe de conductivité aéraulique (Thomson et al., 1997). Ce travail a permis une compréhension fine des transferts gazeux en ZNS, en particulier en frange capillaire.

The research concerns the interactions between vegetation and industrial soils contamined with polyaromatic hydrocarbons (PAH). The approach in situ is based on a phytosociological analysis of the present herbaceous plants on a fallow land of cokeworks combined with physio-chemical soil data. This study shows that there is no particular herbaceous vegetation related to the presence of the HAP in the soil. The experimental approach is based on the study of the development of two grasses, Lolium perenne and Alopecurus Myosuroides. On the polluted soil, a germination delay and a slower development of the roots of grasses are observed. However, no important effects of contaminants on the growth of the abroveground plant parts. The analysis of the contents of HAP in grasses, cultivated in a controlled environment with the atmosphere and the soil separated, shows that grasses are mainly contaminated through the roots. However, no phenomenon of bioaccumulation is observed. Furthermore, a translocation of a part of contaminants of the roots towards the abroveground plants parts is revealed. Long-term attempts show variations of behavior in the transfer of pollutants towards the air parts when plants are cultivated alone or together. In mixed culture, pollutants are almost not absorbed by Lolium perenne. On the contrary, Alopecurus myosuroides transfers in the stalks important quantities of HAP. Furthermore, these longer cultures, showed that the addition of a layer of healthy earth on the polluted soil limits strongly the contamination of vegetation. The question of the impact of vegetation on the decontamination of soils used during the experiments is analysed. The total concentrations of HAP are not significantly decreased after one year of Lolium perenne’s culture. Meanwhile, the concentrations of some contaminants like the benzo[g,h,i]perylene decrease, due to the simulation of microorganisms by the grasses

N supply coming from SOM mineralisation or above-ground litter decomposition was compared with Chromolaena odorata (natural) or Pueraria phaseoloides (improved) 6 month fallow (CS6MF) and 18 month fallow cropping systems (CS18MF) with maize. The capacity of litter to mineralise N during in-vitro incubation was directly correlated with the C/N ratio which were lower for Pueraria (20 à 23) than for Chromolaena (25 à 43). C and N litter dynamics during decomposition were different the two years but were closely fit the double-exponential model simulations. Soil mesofauna and termites were responsible for about 50% at the beginning and about 35% at the end of the total decomposition process. Utter N supply for subsequent maize crops was suggested to be asynchronous since the release of N litters was rapid. N supplies in 6MF cropping systems were globally insufficient and similar for the two species. Upper in situ N soil supply (0-10 cm) for CS6MF during two cropping seasons was weil correlated with N maize uptake and higher with Pueraria fallow. Natural 15N concentration in soil and plant samples showed that the Pueraria litter would contribute for 30 to 87% N maize uptake. After four years upper N soil stock (0-10 cm) was 2. 34 t ha-1 for CS6MF and 2. 83 t ha-1for CS 18MF. N balance between cumulated litter inputs and soil losses suggested that Chromolaena would have a better capacity than Pueraria for N soil maintenance. Upper soil in-vitro incubation (0-10 cm) contributed to estimate that the size of N pool of labile organic matter was higher with Pueraria for CS6MF in relation with lowest lignine 1 N ratio organic residues. This pool was comparable with those obtained for CS18MF

Due to the social and political issues about the restoration of burned forests, this work deals with the impact of forest fires on organic and inorganic matters from forested soils collected in Maures Moutains, taking into account the fire temporal recurrence. This studied site was chosen because every year it undergoes an important pressure from wildfire. Among the three main objectives, the first one was to highlight the impact of the fire frequency on the soil quality, studying more precisely the organic matter and some nutrients. Moreover, we wanted to find fire indicators among many elements and polycyclic aromatic hydrocarbons. Finally, we searched to develop a tool for the management and characterization of burned soils using near infrared spectroscopy. The sampling was done for 2 soil layers in 30 sites involving different fire regimes. After the repeatability test of the employed analytical methods, the results show that fires have an impact on soil. Generally, the fires preferentially affect soil surface layers in a qualitative and quantitative way. If the fires have an impact on the soils, it is usually negative because one year after the last event, the soils present losses of the organic pool and nutrients. In addition, some elements could be considered as potential fire indicators in the long term. Comparatively to the elements, the studied PAH with the lowest molecular masses seem to be good fire indicators in the short term. Lastly, this work enabled to validate and envisage the use of a tool for the burned soil management, by the NIR spectroscopy coupled to chemometrics treatments

This work is a contribution to the study of released aluminium fractionation complexed with Organic Matter (OM) in order to quantify the toxic monomeric aluminium fraction. The natural OM is released in acid forest soil solutions. The characterisation of soils covered with Douglas and chestnuts was performed with usual physico-chemical quantifications (AFNOR) and aluminium selective extractions. Measurement on the soil solutions was related to pH, conductivity, cations concentration (Na, K, Mg, Ca, Fe, Al) and evolution of dissolved organic carbon. Flamme Absorption or Emission Spectrometry (FAAS or FEAS) was used for cation analysis. Total aluminium concentration was determined by FAAS. Total monomeric aluminium was measured by colorimetric analysis with Chromazurol S. The mobile and toxic aluminium fraction was quantified using 2 different techniques : (i) retention of aluminium cationic forms on IR 120 resin, (ii) and adsorption of hydrophobic OM on a nonionic XAD 2 resin. The aluminium release was studied through batch experiments under various conditions for two horizons from the same soil (superior A rich in organic matter and S close to the bed rock). The experiments were carried out at 2 pH values for the horizons alone and also in mixture. Kinetic modelling allowed to calculate soil capabilities to release aluminium. Interactions between 2 horizons in mixture have been emphazised. Finally, dynamic experiments were carried out on the horizons alone and on superimposed layers in order to estimate the influence of the A layer on the S horizon. Soil leaching realised with various aqueous solutions pointed out the capability of the horizons to fix or release free aluminium

Afforestation of prairie regions has rapidly reached, as a recent world-wide policy, countries like Uruguay, but little is known about the effects of eucalyptus plantation on soil organic matter (SOM) dynamics. In order to evaluate their possible effects in a prairie soil, some soil parameters were compared, before and after forestation. The zone of study was located 200 km from the Rio Uruguay mouth (Piedras Coloradas-Algorta) in a 1200-mm temperate gently undulated sandy lowland dominated by Mollisols with an herbaceous vegetation of photosynthetic pathway C4 type. The study included two stages; in the first one, a 25-year old C3 type cultivation (Eucalyptus grandis) and eight soil parameters (organic matter, pH, cation exchange capacity (CIC) Ca2+, Mg2+, Na+, free and amorphous Fe) are considered. The soil samples were taken also by horizons (A and B). The data obtained was statistically evaluated by t-tests and analysis of variance (ANOVA). In the second stage the cultivation time and parcel number were increased and the sampling was made on the less resilient (0-20cm) depths. Here, the key parameters were restricted to C (TOC and δ13C) pH and apparent density. From the overall 30 years data set it arises that there is an effective loss of total organic carbon (TOC) in soils cultivated with eucalyptus and that the lower mean residence time of C derived from the eucalyptus is responsive of the total soil carbon decline. The TOC decline was related with the age of the plantation for most of previous land uses and with a change in other parameters (pH, apparent density, CIC, Ca2+, Mg2+, Fe3+ and 1:1/2:1 clay balance). Eucalyptus affects the C balance of soil and it is explained by an increase of its turnover. The soil C sequestration in afforestation projects appears questionable in Uruguayan mollisols

New Caledonian ferritic soils (more than 50 % of iron) are naturally rich in metals (chromium, nickel, cobalt, manganese) and deficient in nutrients (nitrogen, phosphorous, potassium). Nevertheless, New Caledonia is recognized as a hot spot of vegetal biodiversity, and is a natural laboratory for studying adaptation strategies of plants to metalliferous soils, and more particularly the (hyper)accumulation phenomenon of metals by plants. Understanding those mechanisms is notably needed to develop revegetalization techniques of ecosystems after mining exploration or phytoremediation of polluted sites for instance. Thus, to better understand soil-plant relationships, speciation and localization of manganese and nickel in all vegetal organs of different species and in soils were studied. In spite of a different speciation in soil, both nickel and manganese are under similar divalent organometallic complexes in plants, from roots to leaves, mainly in tissues with less active metabolism

The changes in land use of contaminated agricultural soils are susceptible to modify their trace metal availabilities by changing the quality and quantity of soil organic matter. But the role of soil organic matter in the determinism of trace metal availabilities in contaminated soils is not well known. The objective of the present study was to assess the role of soil organic matter in determinism of trace metal availabilities and their dynamics in contaminated soils varying in their texture and nature of pollution. A strategy of studying Cu, Pb, Zn and Cd availabilities of two sites with different texture and origin of pollution was adopted and the role of organic matter was assessed through; 1) sampling the soils of two parcels at each site with two different land uses i.e. under annual crop and under perennial energy crop miscanthus, 2) changing the soil organic matter of these soils through in vitro soil incubations. A combined approach of chemical metal extractions and metal localization study in different soil size fractions was used. The results of the trace metal availabilities of the soil under miscanthus compared to annual crop soil showed that the influence of changes in organic matter through land use was different at both sites. In the silty clayed soil, the availability of Cu and Pb which are the metals known to be preferentially bound to organic matter was decreased with an increase in their localization in soil finer fractions. In the site with organic matter rich sandy soils the availability of metals which are known to be bound to soil mineral phases i.e. Zn and Cd was changed without a change in their localization. The results of laboratory incubation experiments revealed that the mineralization of soil organic matter affects the trace metal availability in two ways. Cu and Zn availabilities are changed in all soils whatever the texture while Pb and Cd availabilities changed only in sandy soils. This difference of the change of metal availabilities in both cases of organic matter variations i.e. between the soil samples under different land use and in the samples of laboratory incubations can be explained by the fact that the changes in organic matter were not similar in both cases. Our work on the metal enriched particulate organic matter (POM) fractions, the most labile organic matter fractions showed that POM act as source and sink of the metals in our conditions and POM associated copper is bioavailable in liquid medium but its bioavailability is less than the metal added as salt solution. These results, increasing the understanding of the role of soil organic matter in the determinism of trace metal availability in different textured soils, are discussed
