Full textThe doctoral dissertation evaluated the results of quantified concentration levels of lipophilic persistent and emergent organic pollutants in sediment samples collected from ten representative localities in the central Danube region. Based on the conducted laboratory and field research, the spatial distribution of compounds in the studied area was defined. Using multivariate techniques, the experimental results were successfully modeled by statistical methods that differentiated the sources of contamination for the total set of tested pollutants. A risk assessment of contaminated sediment on aquatic organisms and the human population according to carcinogenicity of the tested compounds is presented in thesis. Different exposure scenarios of ingestion and dermal contact, depending on the time exposure and exposed surface skin of potential receptors, of different ages and sex, are presented. For the first time in the study area, an ex-situ equilibrium passive sampling methodology was implemented using silicone rubber sorption medium tested at different polymer-sample sediment mass ratios. Using the method, the freely dissolved concentrations of lipophilic contaminants in pore water were successfully obtained as predictors for determining the bioavailability of the compounds.

Full textMicroplastics are ubiquitous in aquatic ecosystems, so it is essential to study their impact on the behaviour of other compounds which are commonly present in water. The term microplastics refers to all plastic particles smaller than 5 mm. In order to address knowledge gaps relating to the potential harmful effects of microplastics in the environment, the experiments conducted during this thesis were designed to investigate the adsorption mechanism of chlorinated phenols, benzene derivatives, and polycyclic aromatic hydrocarbons on microplastics in water. To provide a more detailed understanding of the influence of different water matrices on adsorption properties of microplastics, experiments were conducted in both synthetic and real water matrices. In the course of this work, methods were optimised for the isolation and characterization of microplastifrom personal care products, in order to allow investigation of the influence of the properties of primary microplastics on their interactions with organic pollutants.Base on the obtained results, it can be concluded that the optimal method of isolating microplastics from personal care products is based on treating already dried material with 30% hydrogen peroxide, after extraction of the agent in distilled water, in order to obtain cleaner microplastic samples. The mixing rate was found to have a significant effect on the degree of adsorption of the investigated organic compounds. Increasing the mixing speed led to a higherdegree of adsorption, with the maximum adsorption percentage reached at amixing speed of 150 rpm. In addition, the dispersion of powdered materials in the water had no significant effect on the degree of adsorption of chlorinated phenols, benzene derivatives, and polycyclic aromatic hydrocarbons on microplastics.The adsorption equilibrium between the concentration of chlorinated phenols, benzene derivatives and polycyclic aromatic hydrocarbons in water and selected types of microplastics (PEp, PE_PCPs_1, PE_PCPs_2, PEg, PET, PP, and PLA) was established after 24 and 48 h of contact time, depending on the selected group of organic pollutants. The adsorption affinity of chlorinated phenols, benzene derivatives, and polycyclic aromatic hydrocarbons towards microplastics was influenced by both the physicochemical properties of the compounds and the characteristics of the microplastics. Based on the kinetic experiments, the highest adsorption affinity for microplastics was shown by benzene derivatives (qt=103-350 µg/g), while the lowest was observed during the adsorption of chlorinated phenols (qt=25-225 µg/g). Benzene derivatives showed higher adsorption affinities for the selected microplastic particles than the polycyclic aromatic hydrocarbons and chlorinated phenols which had similar logKow values. The influence of the water matrix on adsorption of chlorinated phenols, benzene derivatives, and polycyclic aromatic hydrocarbons on microplastics depended on the specific functional groups of the investigated compounds as well as on the type of microplastics. Water matrix had little impact on the adsorption of polycyclic aromatic hydrocarbons on microplastics but greatly impacted the adsorption of chlorinated phenols. Fitting the pseudo-second order kinetic model to the adsorption data of chlorinated phenols, benzene derivatives, and polycyclic aromatic hydrocarbons on microplastic particles resulted in high correlation coefficients, indicating that chemisorption is the likely adsorption mechanism. In addition to the high correlation coefficients obtained for all the organic pollutants investigated, the pseudo-second order rate constants obtained were lower than the initiaadsorption rate, indicating significantly faster adsorption at shorter contact times (12-24 h), with adsorption slowing down as equilibrium was reached.The adsorption mechanism of chlorinated phenols, benzene derivatives,and polycyclic aromatic hydrocarbons was investigated using Freundlich,Langmuir, Redlich-Peterson, Dubinine-Radusckevich, and Temkin adsorption models. The Freundlich exponent values for the adsorption of chlorinated phenols, benzene derivatives, and polycyclic aromatic hydrocarbons were less than 1 which indicates that the free energy of adsorption of these compounds on microplastics decreases as the initial concentration increases. The maximum adsorption capacities of PAHs on microplastic particles were in the range of 29.7-2596.5 µg/g. High maximum adsorption capacities were also obtained for the adsorption of benzene derivatives on the tested types of microplastics: 39.3-2010.1 µg/g. The chlorinated phenols behaved differently, and were more effected by the water matrix, with qmax values in the range 20.00-205.6 µg/g. The pH of the water matrix was found to have a significant effect on the adsorption of chlorinated phenols on microplastics, whereas in the case of benzene derivatives and polycyclic aromatic hydrocarbons, the degree ofadsorption was largely independent of the water pH. For the adsorption of chlorinated phenols on microplastics, neutral pH conditions resulted in the greatest degrees of adsorption (55-65% at pH 7), while adsorption was inhibited under acidic (8-35% at pH 4) and basic (15-35% at pH 10) conditions. The microplastic type with the lowest observed adsorption affinities was PLA. It can be thus be assumed that in the event that this type of microplastic enters water systems, organic pollutants will only adsorb weakly to this material, such that it will have significantly less impact on the transport of the se compounds through the environment, than the other tested types of microplastics. The results obtained in this research demonstrate that the adsorption of the selected groups of organic pollutants on the microplastics investigated is significantly controlled by the physicochemical properties of the tested compounds, such as the dissociation constant, molecule size, hydrophobicity,structural properties, etc. In addition, the characteristics of the water matrix play an important role in controlling adsorption of organic pollutants on microplastic, especially the water pH. In addition, the structure and aging of the polymers had a major influence on their interactions with the selected organic pollutants. The obtained results also demonstrate the difficulty in determining a uniform mechanism of adsorption between the various organic compounds and microplastic particles in water.

Full textNatural organic matter of soil/sediment make the main region for sorption of hydrophobic organic compounds, ant its properties influence the degree of retention and, consequently, (bio)availability of organic compounds. In order to assess the ecotoxicological risks of contaminated soils/sediments to the environment and design the appropriate remediation strategy or predict the fate and transport of organic pollutants in contaminated zones, it is necessary to understand the mechanisms of sorption/desorption at the level of the mechanism of established bonds. Study of the sorption and desorption of selected hydrophobic organic pollutants, pentachlorobenzene and lindane, on sequentially extracted humic acids and humins from a single sediment sample with the aim of finding the relationship between the structural characteristics of the isolated humic acids and humin and sorption and desorption parameters. Sorption affinity, nonlinearity of isotherms, and apparent sorption-desorption hysteresis were correlated to the sorbent characteristics obtained from elemental analysis and FTIR spectroscopic data. The proposed sorption mechanism on humic acids assumes that at low concentrations of pentachlorobenzene and lindane the sorption sites in the condensed aromatic region are occupied first, and then, at their higher concentrations, the sorption sites in the amorphous and aliphatic regions. Generally higher nonlinearity coefficient obtained for the sorption of pentachlorobenzene on umic acids compared with the nonlinearity of sorption isotherms for lindane, indicate that in the overall sorption of pentachlorobenzene of higher significance is the echanism of distribution and insertion of pentachlorobenzene molecule into hydrophobic dips of humic acids, compared to specific adsorption. These conclusions were confirmed with the results of spectroscopic investigation of intermolecular interaction of chosen organic compounds and N-methylformamide.Since suggested sorption mechanism could not explain sorption of pentachlorobenzene and lindane onto humin samples, it is supposed that the nonlinearity can be a result of surface interactions, while the high sorption affinity is result of distribution of organic compounds in the amorphous aliphatic regions that offer an excellent environment for sorption.With the aim of further insight into the sorption mechanism, investigation of desorption kinetics of three chosen hydrophobic organic compounds, pentachlorobenzene, lindane and pentachloroaniline, in the presence of soild adsorbent XAD-4 macroporous ion-exchange resin was performed. On the basis of the results obtained for sediment sample and fraction < 125 µm at two equilibrium times (15 and 90 days) and for all selected organic compounds, it can be concluded that the assessment of the potential (bio)avialable fraction of organic compounds may be obtained by using simple method of desorption in the presence of XAD-4 macroporous ion-exchange resin, performed in two ways: (1) by sediment extraction during 24 hours, when the desorbing fraction corresponds to the fraction of he compound that is found in the fast-desorbing domain of organic matter, or (2) by 6-hour extraction, when the desorbing fraction corresponds to one half of the fraction appearing in the fast-desorbing domain of the organic matter.

Full textThe goal of this thesis was to examine removal possibility of high concentrations of organic and inorganic matter from aquatic solution using “Cross-flow” spiral wound nanofiltration membranes. Natural organic matter, ammonia ions and total arsenic removal was examined using concentrates – waste water obtained from industrial nanofiltration plant and they present NFCP experiment series. Removal of high concentrations of calcium, magnesium, iron and manganese ions was a part of NFWP experiments and was conducted using natural groundwater. Optimal fluxes and transmembrane pressures, as well as complexing substances dosage concentrations were determined. Obtained results in semi industrial scale are practically applicable on the large scale plants for drinking water preparation from deep wells, as well as from shallow aquifers. Application of presented results, concerning drinking water preparation from deep wells with significant savings of water resources, is designed especially for locations in Pannonia basin. Shallow aquifer well water treatment is applicable in practice especially because of addition of organic complexation agents that substitutes conventional deferization and manganese removal methods ultimately reducing investment and exploitation costs. On the basis of obtained results, industrial plant that produces drinking water from Zrenjanin aquifer deep well was designed. Furthermore, potable water industrial plant was designed that used shallow aquifer well water located in Bačka Palanka region, settlement Despotovo.

Full textThe aim of the research in this PhD dissertation is the assessment of the potentially biodegradable fraction of selected organic pollutants (pentachlorbenzene, hexachlorobenzene, lindane, trifluraline, 4-octylphenol and 4-nonylphenol) in the sediment, estimation of the biodegradation potential of these compounds in sediment in different conditions, as well as the assessment of the stabilization potential sediment by the sediment amendment with of carbon rich sorption agents. In order to develop and optimise methods for the bioavailability assessment of the selected organic pollutants, methods of multistage and single-step non exhaustive extraction were studied using the following chemical agents: Tenax resin, XAD -4 resin and a cyclodextrin solution (2-hydroxypropyl- β-cyclodextrin, β-cyclodextrin and methyl-β-cyclodextrin). Results showed that optimal agent for estimating the bioavailable fraction of selected organic pollutants from the sediment is XAD-4 resins, and that the optimum extraction time using single-step extraction is about 8 h. The assessment of the biodegradation potential of selected priority organic pollutants in the sediment was examined in various aerobic and anaerobic conditions, with the optimization of conditions through biostimulation and bioaugmentation. It has been shown that all six selected compounds possess significant biodegradation potential in the anaerobic environment, where in the case of lindane and trifluraline there is complete removal of the bioavailable amount of the compound using all four inoculum tested. Aerobic potential under the applied conditions has been showen only for alkyl phenols, where almost all of the bioavailable fraction of the compound in the sediment was removed (78-85%). The potential of sediment remediation with the amendment of sediment withcarbon rich materials was examined from the aspect of selecting carbon sorption agents (activated carbon, biochar and humus); estimation the optimal material doses; the long -term and short-term effects of the addition of these agents on the bioavailability of organic pollutants in order to examine the effect of aging and the toxicity of the resulting mixtures. The results of the stabilization of pollutants in the sediment show that: (1) increasing the dose of all three sorption agents leads to an increase in the immobilization efficiency and reduction of the bioavailable fraction of the selected organic compounds; (2) aging of the amended sediment during the first 90 days results in a further reduction of the biodegradable fraction of all compounds, after which the biodegradable concentration of the selected compounds remain the same in the case of activated carbon amendment, while the bioavailable fraction of the compound increases with the use of biohar and humus. Phytotoxicity tests showed that Zea mays accumulated significantly higher amount of selected organic pollutants from unamended sediment, comparing to Cucurbita pepo and Lactuca sativa. Toxicity of activated carbon and humus amended sediment assessed by Vibrio fischeri luminescence inhibition test and by measuring Zea mays germination and biomass yield was significantly reduced in the amended sediment samples. Accumulation of the selected organic pollutants in the Zea mays biomass in the unamended sediment were a significantly higher than in the humus and activated carbon amended sediment. Both sorbents show potential to be used as remediation agents for organically contaminated sediment, but activated carbon exhibited the better performance.
