Der volle Inhalt der QuelleSix organisms were tested for their ability to grow in the presence of six different industrial plasticizers. Two bacteria, Rhodococcus rhodochrous and Arthrobacter paraffineus, grew well in media containing n-hexadecane and one of the plasticizers.
Fermentations in a 2-liter reactor were performed with Rhodococcus rhodochrous and three plasticizers: bis 2-ethylhexyl adipate, dioctyl phthalate and dioctyl terephthalate. The organism degraded all of the adipate, half of the terephthalate was degraded and the phthalate was degraded slightly.
In these growth studies, the toxicity of the media increased as the organism grew. This trend was linked to the accumulation of metabolites from the partial degradation of the plasticizer. The two major metabolites were identified as 2-ethyl hexanol and 2-ethyl hexanoic acid. The alcohol was only observed part way through the growth in the presence of the adipate. Its concentration decreased as it was oxidized to the acid and it was not present at the end of the fermentation.
The acid was observed for all three types of plasticizers and it was present in high concentrations at the end of every experiment. The nature and pattern of production of the metabolites were consistent with a pathway for the degradation of all three plasticizers by hydrolysis of the ester bonds.
The accumulation of toxic metabolites indicates that biodegradation may not be a solution to reducing environmental impacts associated with plasticizers that have leached into the environment.

Der volle Inhalt der QuellePlastics are technical materials necessary for industrialized societies. However, in the early 2000s, plastic particles of about ten microns were observed in seawater samples. These are called "microplastics". Their presence in most environments has been progressively highlighted making it an anthropocene marker. Moreover, these particles interact with environments and may carry toxic additives or micropollutants. However, scientific and technical barriers limit this accurate evaluation. In this context, the aims of this work are (1) to determine the most efficient and cost- effective extraction conditions of microplastics trapped in sand and (2) to evaluate the toxicity due to the interactions between micropollutants and aged plastics, which can occur in the marine environment. Thus, an elutriation system prototype has been built and an adapted protocol developed to efficiently extract microplastics from sand. In order to determine the optimal elutriation flow velocities, a simple numerical model based on hydrodynamic equations has been developed. This numerical model has been validated by comparing theoretical and experimental results. However, these results also demonstrate that process optimization was required: based on different constraints, for example the time needed to achieve the elutriation or the size of the column, new data on the design have been acquired. The evolution of the surface state and the toxicity of 3 types of plastic (PVC, PET and PBAT) immersed in the marine environment during 550 days was studied on Kernevel harbor (Larmor-Plage, France). The results of the plastics ageing show very different behaviors. PBAT ages faster than PVC whereas PET does not exhibit large modifications. The aging of PVC is accompanied by a loss of compounders characterized by an estrogenic activity and by the adsorption of heavy metals. In the marine environment, the degradation of the PBAT surface forms cavities in which clay particles can be trapped. Moreover, in a more punctual manner than PVC, this material exhibit strong estrogenic activities

Der volle Inhalt der QuelleOceanic plastic pollution is of major concern, with several million tons of plastic dumped in the ocean every year that are causing health threat to marine creatures. Impacts have been found at all the trophic chain levels from the zooplankton to the megafauna, but little is known on its impact on the microbial life and its crucial role in the oceanic ecosystem functioning. The objective of this thesis was to study the ecotoxicity of plastics in the marine environment. The first handled question was: how much the abundance, diversity and activity of bacterial life growing on plastic, i.e. the ‘plastisphere’ are driven by the chemical properties of the polymer and the environmental changes (Chapter 2)? Polyethylene (PE) and polylactide acid (PLA) together with glass controls in the forms of meso-debris (18mm diameter) and large-microplastics (LMP; 3mm diameter), as well as small-microplastics (SMP; of 100 m diameter with spherical and irregular shapes) were immerged during 2 months in seawater. We found that the plastic chemical composition, the successive phases of biofilm formation and the phytoplankton-bacteria interactions were more important factors driving the abundance, diversity and activity of the plastisphere as compared to material size and shape. The second handled question was: would the microplastic (polystyrene PS; 50-100 µm; three concentrations) together with their mature biofilm be toxic for the marine filter-feeder Branchiostoma lanceolatum and how much the plastisphere can influence this toxicity (Chapter 3)? We used a large set of complementary techniques to follow the microplastic ingestion (microscopy quantification) and the modification of the gut microbiota (16S rRNA Illumina Miseq sequencing), the gene expression of immune system, oxidative stress and apoptosis (Nanostring) and also histopathology (transmission electron microscopy). No obvious toxicity was observed, while microplastics could be a vector for bacteria to the gut microbiome, can induce more goblet cell differentiation and can surprisingly have a positive effect by supplying nutrients to amphioxus in the form of bacteria and diatoms from the plastisphere. The third handled question was: how much the conventional petroleum-based microbeads classically used in cosmetics can be substituted by other polymers for their biodegradability by the plastisphere in marine environment? (Chapter 4). We used complementary techniques to follow the 4 biodegradation steps including biodeterioration (granulometry, gravimetry and FTIR spectroscopy), biofragmentation (size exclusion chromatography, 1H nuclear magnetic resonance and high-resolution mass spectrometry), bioassimilation and mineralization (1H nuclear magnetic resonance and oxygen measurements). We concluded that microbeads made of polyhydroxybutyrate-co-hydroxyvalerate (PHBV) or rice and in a lesser extend polycaprolactone (PCL) and apricot were good candidates for substitution of conventional microplastics, classically made of PE or polymethyl methacrylate (PMMA) that were not biodegraded under our conditions. Interestingly, the biobased PLA was not biodegradable but the petroleum-based PCL was biodegradable under our marine conditions

Der volle Inhalt der QuellePlastic containers are either food or non-food grade. The food grade containers are used under the well-regulated conditions by various developed countries, to ensure that the pollutants cannot diffuse into food. In Africa and Cameroon in particular, this regulation does not exist. In addition, it is an area of great smuggling, and the use of non-food grade containers in the preservation of food is practiced. Plastics are made up of long polycarbon chains called polymers whose good mechanical, electrical and thermal properties come from the addition of additives during their formulation. Among these additives, bisphenols and phthalates are used respectively as antioxidants and plasticizers. These molecules have been recognized as dangerous for human health because they are endocrine disruptors and are involved in many cancers. The main route of entry of these molecules into humans is food. Their migration from plastic containers to food is facilitated by storage conditions, processing methods and the nature of food. The objective of this work is to study the transfer of bisphenols and phthalates from plastic containers to food matrices. It was a question of identifying the risks of human contamination by plastic containers through a survey of households and industries. Then, the evaluation of the exposure of the population went through the development of a method based on liquid chromatography-tandem mass spectrometry to quantify these molecules in food matrices. Finally, the study of the transfer of phthalates from paint buckets to food was carried out via experimental design and the kinetic study. This work showed that 36.5% of households used old paint buckets in food, and this use did not depend on social class. Derivatization methods followed by liquid chromatography analysis have proven to be precise and rapid for the quantification of bisphenols (A, B and F) and total phthalates in foods. The estimated dietary daily intake of bisphenols and phthalates through foods remains low in Cameroon. The kinetic study revealed that the migration of phthalates is best described by the pseudo-second-order model and depends mainly on temperature, contact time, and pH. These parameters present significant interactions

Der volle Inhalt der Quelle"Guolaosi" eller död från överarbete är ett fenomen som i regel uppkommer bland utvecklingsländer. Dödsorsaken är huvudsakligen genom stroke. Offrens yrken varierar allt från professorer, IT-arbetare till läkare. De delar dock en sak gemensamt; att arbeta under långa perioder stillasittande. Projektets mål var att utveckla en produkt som minskar dödliga följderna av sedentära överarbete, genom att förebygga en av de tre orsakerna för att utveckla blodproppar; saktad blodström. Målgruppen var då kineser av de yrken som hade tidigare drabbats av fenomenet. För att samla informationsrika data om fenomenet genomfördes en kvalitativ studie i Kina under två månader. Genom att göra en omfattande strukturerad provtagning kunde informationsrika data samlas under en kort tidsperiod. Fältstudien bestod av observationer, frågeformulär och en intervju, som då tolkades till kundbehov och eventuellt produktspecifikationen. Den slutliga produkten kom att bli ett par byxor med en inbyggd dynamisk komprimeringsmekanism, som kan komprimera venerna under sittande aktiviteter, för att förhindra saktad blodström. Kompressionsmekanismen fungerar som den kinesiska fingerfällan. Den komprimerar blodkärlen medan personen sitter och sträcker benen framåt. Produkten är konstruerad på så sätt att den kan tillverkas endast av polysackariders tråd, från bomull och majs. Vilket är lämpligt för Kinas lokala resurser.
