Texto completoPolymeric materials are widely used for the infusion of medications, but they are known to interact with certain drugs. Container-content interactions between a medical infusion device and a drug are likely to alter the therapeutic care of the patient through the release of additives or loss of drug through sorption. These interactions are variable, and depend on the composition of both the device and the drug (active ingredient, excipients).The study focuses on the interactions between infusion tubes and drugs diluted in water-based solution. Two active pharmaceutical ingredients (API) with different lipophilicity were studied: paracetamol and diazepam. Different polymers are studied for infusion tubings: polyethylene (PE) and polyvinyl chloride (PVC). PVC tubings are plasticized with plasticizers to obtain the needed flexibility and ease of use. In this work three plasticizers were selected: DINCH, DEHT (DEHTP) and TOTM (TEHTM).Drug solutions were put into contact with the various infusion tubes. Liquid chromatography was used to quantify the API and plasticizers in the solutions after contact with the infusion tubings. This experimental study made it possible to follow changes in the concentration of the API and plasticizers in the solution, by varying the contact time.Molecular simulation allowed better understanding of the sorption phenomena and of the plasticizers’ migration at molecular and interfacial level, whilst considering the interactions and the miscroscopic specificities. Energy characterizations were used to gain an improved understanding of the interactions leading to drug adsorption and plasticizer release. The Potential of Mean Force (PMF) method was used to calculate the free energy associated with adsorption of the API.Initially, the study focused on sorption phenomena, more specifically on interactions between API and PE and pure PVC surfaces. This first step enabled us to study the interactions with more complex surfaces, such as plasticized PVCs. Finally, the last part studied the release of the plasticizers into the solution in contact with the tubings, as well as the influence of the composition of the solutions on the adsorption of the APIs.In conclusion, the experimental results validated the simulation methodologies, whilst the simulation results provided a molecular vision of the API adsorption and plasticizer migration phenomena. The combination of these two approaches offers considerable added value for the design of new materials and/or the rationalization of experiments

Texto completoNowadays, 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)

Texto completoWater pollution resulting from the excessive presence of nitrogen nutrients arising from agricultural practices and human activities such as the discharge of domestic and industrial wastewater has become a major environmental problem. The main objective of this study is to optimize the formulation of new adsorbents for the removal of ammonium ions contained in agricultural runoff. For this purpose, two mesoporous materials functionalized with arene and propyl sulfonic acid groups by cocondensation and post-synthesis grafting on the one hand and a novel adsorbent containing a bridged benzene moiety on the other hand were synthesized. They have been characterized and tested in batch and continuous modes. Arene and propylsulfonic acid adsorbents with an organosilane/silica molar ratio of 20% show a maximum adsorption capacity of about 25 mg NH4+/g at the lowest temperature studied (5° C). For a given initial ammonium concentration, the removal efficiency (W) increased with increasing adsorbent loading. The adsorption capacity was improved by increasing the molar organosilane silica ratio to reach 42 mg NH4+/g with a ratio of 40% at 25 ° C. The equilibrium data of both adsorbents followed the Langmuir model and the kinetic pseudo second order model is the one that best describes their kinetic behavior. Negative values of the enthalpy (ΔH0) and entropy (ΔS0) obtained indicate that the reaction is exothermic and that there is downward of the random arrangement of the adsorbate at the solid/liquid interface, respectively. Finally, the adsorbents are regenerated easily and maintained their adsorption capacity after five consecutive cycles of adsorption-desorption. The continuous study was conducted with the arene sulfonic acid adsorbent synthesized by grafting. The results obtained show that the time of occurrence of breakthrough curves decreases with increasing flow rate and initial ammonium concentration, but increases with increased bed height. Thomas and Yoon-Nelson models allowed a good prediction of experimental breakthrough curves. Finally, the breakthrough curves were not changed significantly after three consecutive cycles of adsorption-desorption. With the adsorbent containing the bridged benzene group, adsorption capacities between 34 and 40 mg NH4+/g were obtained.

Texto completoPrevious studies have shown that the use of Acohol-Based Hand Rubs (ABHRs) has been associated with reduced rates of nosocomial infections. However, the quality of hand rubbing with ABHRs has rarely been evaluated. The first aim of this work is to evaluate the quality of hand rubbing and skin tolerance to ABHRs in the long term. The consequences of systemic passage of alcohol by inhalation or dermal absorption during intensive use of these products in hospitals remain a subject of debate. The second aim of our work is to assess the exposure of Healthcare Workers (HCWs) to ABHRs, under experimental conditions in the laboratory and under a real situation of work shift in hospital. Our study demonstrated a decrease in the quality of hand rubbing. The use of these products increases skin hydration. ABHRs are well tolerated by HCWs and do not dry the skin.The measurements made in the laboratory showed that exposure to ethanol during ABHRs handling is of short duration but at high concentrations. The quantification of ethanol in ambient air of a patient room for eight hours of ABHRS intensive use showed that the patient and HCW are exposed to the same amount of ethanol vapours. However this amount remains far inferior to the French guidelines for professional exposure limits to ethanol over 8 hours. The hospital study showed that exposure of HCWs to ABHR at short term does not lead to detectable absorption of ethanol and its metabolites. Quantification of ethanol vapour in the inhaled air remains well below the levels known to be toxic in humans. The whole project takes place over 10 years; it will verify the potential side effects associated with the ABHRs use for a long-term
