Full textNowadays, environmental problems related to soil pollution with heavy metals are numerous, therefore, it is important to understand metals behavior in soils and to appreciate their transfer. The fate of the metals in the environment is closely related to their interactions with the major reactive soil compartments (organic matter, iron and manganese oxides, clays). The objective of this work is to develop an approach based on the combination of several model to study metal ion speciation in the soil and the soil solution. Models used to describe the interactions of metals with the main reactive phases in the soil are CD-MUSIC (amorphous and crystallized iron oxides), NICA-Donnarf (organic matter and manganese oxides), cationic ion exchange model (clays). First, this work implies the definition of generic parameters to describe the interactions of the studied metals (Cd, Cu, Pb and Zn) with iron and manganese oxides, a part of this information is missing in the literature. Then, after the validation of the approach by comparison with analytical results, this multi-surface model is applied to two contaminated soils located in the North of France (atmospheric deposits) and in Brittany (intensive pig manure applications)

Full textThis thesis relates to the study of parameters which influence the dynamic of nickel and its radionuclide 63 Ni in soils. At the Saille time, the study of the chemical and biological characteriza- tion of these elements availability in the soils is done. The available pool of Ni and 63 Ni (chemical estimation) was measured by chemical and isotopic methods and soil incubations; by evaluating the interest and limits of each roethod. The factors which influence the mobility of metal in soils were thus determined. With through this study, we showed that the bio- and phyto-availability of Ni depend on the soil mineralogy, on the soil weathering, on the type of metal associations with the mineraIs, and on the quantitative presence of these mineraIs. The transfer of Ni and 63 N i from the soil to the plant depends on the metal availability in the soil and on the roots behaviour to the soil offe1, in relation to the strategies of hyperaccumulation, accumulation or exclusion of N z. Plants are able to modify the metal availability in soils by influencing the sorption processes of Ni from the solid phase to the soil solution. They are also able to change the speciation of Ni in solu- tion however the majority form of Ni in the soil solution was N i2+. Hyperaccumulators regulate Ni and 63 N i concentration in soil solution and their migration to the ground water. If the physico-chemical properties of soils, the pollutant availability and the choice of the hyperaccumulators are taken into account, the se plants are able to decrease and control durably the ecotoxicological effects of trace elements and radionuclides contamination in soils

Full textSurface and deeper horizons developed in 22 parent materials were sampledin the agricultural and forest soils of Northern France. Total contents of 18 trace elements and two major elements (AI, Fe) were determined in 758 horizon samples, together with the pedological characteristics. Ln the deep horizons, the positive linear correlations of the less mobile trace elements (Bi, Co, Cr, Cu, ln, Ni, Pb, Sn, TI, V, Zn) contents with lutum(particles < 2μm), AI and Fe contents suggest that trace elements are closely associated to alumino-silicates and iron oxi-hydroxides of the finest solid phase. These correlations are close and are common to the deeper horizons of ail the parent materials, whatever their age and type. The processes of the sedimentary rock genesis, including ancient pedogenesis, did not cause any major segregation of the less mobile elements. The mobile elements (As, Cd, Hg, Mn, Mo, Sb Se) show less close relationship with the minerai phase, except Cd and As which seem particularly associated to Mn and Fe respectively. Mercury, Mn and Se show strong links with the organic matter in the deep horizons. Soit parent materials often show an enrichment with the mobile elements. Most of the calcareous rocks are enriched with Cd. Enrichments with ail trace elements, except with Co, Cr and Ni, were found in the surface horizons

Full textThis thesis dealt with the determination and study of the ecodynamics of trace metals in technosols highly contaminated in metals and metalloids in the context of natural revegetalisation or phytoremediation. Two sequential extraction schemes were used jointly with selective extractions in parallel with the determination of the total metals concentration in soils, the total dissolved metals concentration in the soil pore water, the metals labile pool (DGT) and germination tests with dwarf beans to investigate the speciation, mobility and phytoavailability of (Zn, Pb, Cd, As and Sb) for technosols of two post-mining (La Petite Faye) and industrial (Mortagne du Nord) sites. Additionally, young plants of P. euramericana Dorskamp were cultivated in rhizobox on Mortagne du Nord technosols to investigate the rhizospheric effect on the mobility of metals. Moreover, the effect of nitrogen addition under nitrate and ammonium on the behavior of these metals has been investigated for P. euramericana Dorskamp for the same soils. Despite the high total metals and metalloids concentration in the La Petite Faye soils, the mobility of these potentially toxic elements is limited because of their association with the residual fraction. The phytoavailability is also limited and correlated with the labile pool of technosols. The culture of P. euramericana Dorskamp generated a rhizospheric effect characterized by an increase of the pH and concentration of dissolved organic carbon (DOC) in the soil pore water and a decrease in the total dissolved concentration of metals (Zn, Pb et Cd) in the soil pore water. The addition of nitrogen under nitrate or ammonium respectively increased and decreased the soil pore water pH and in the case of ammonium the DOC also increased and stabilized metals in the rhizosphere in comparison to control soils

Full textThe presence of large amounts or mobile fraction of lead (Pb) in soils is undesirable because Pb is highly toxic even in minor quantity in the environment. The remediation of Pb in calcareous soils with high amount of metallic trace metals (MTE) can be achieved by phytostabilization or induced phytoextraction processes. For this purpose, a greenhouse study was carried out to determine the effects of elemental sulfur (S0) and mineral fertilizers (N-P-K) followed by the addition of high amounts of sulfuric acid (H2SO4) to cultivated soils on the soil chemical fractions of Pb, growth parameters and uptake and accumulation of Pb in willow (Salix miyabeana) grown in a calcareous soil (mean pH 7.55) rich in MTE. The results indicate that in near neutral and weak alkaline conditions, willow accumulates very small amount of Pb (<1 mg / kg d.w, below the detection limit) in the leaves. Nevertheless, some proportion of soil Pb can be mobilized by plant roots, particularly under acidic conditions. Willow accumulates more Pb in the roots than in other plant parts, regardless of the nature of soil treatments. Soil pH plays an important role in the uptake and accumulation of Pb in willow parts. However, a pH value less than 5.5 tends to produce an excess of Pb removal and causes inhibition of leaf growth or a considerable reduction in leaf yield. This is to be considered when attempting to reduce the pH value of a calcareous soil rich in MTE to less than 6.5, in order to enhance the soil-plant transfer of Pb.

Full textThe 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
