Das Internet der Dinge (IoT) ist ein Konzept, bestehend aus vernetzten physischen Objekten, welche in die virtuelle Welt integriert werden um aktive Teilnehmer von Geschäfts- und Alltagsprozessen zu werden (Uckelmann, Harrison and Michahelles, 2011; Shrouf, Ordieres and Miragliotta, 2014). Es wird erwartet, dass dieses Konzept einen großen Einfluss auf Unternehmen haben wird (Council, Nic and Intelligence, 2008). Geschäftsmodelle kleiner und mittelständischer Unternehmen (KMU) sind bedroht, sollten sie den sich abzeichnenden Trend nutzen (Sommer, 2015). Daher ist das Ziel dieser Arbeit, eine exemplarische Implementierung von vernetzten Geräten in einem kleinen Unternehmen um seine Vorteile darzustellen.
Diese Arbeit verwendet Design Science Research (DSR) um einen Prototyp zu entwickeln, der auf dem Anwendungsfall einer Holzwerkstatt aufbaut. Der Prototyp besteht aus einem physischen Sensor und einer Webapplikation, welche von dem kleinen Unternehmen zur Verbesserung seiner Prozesse genutzt werden kann. Die Arbeit dokumentiert den iterativen Entwicklungsprozess der Prototypen von Grund auf zu nutzbarer Hard- und Software.
Der Hauptbeitrag dieser Arbeit ist die beispielhafte Anwendung und Nutzung von IoT in einem kleinen Unternehmen.
Agricultural land-use may lead to brief pulse exposures of pesticides in edge-of-field streams, potentially resulting in adverse effects on aquatic macrophytes, invertebrates and ecosystem functions. The higher tier risk assessment is mainly based on pond mesocosms which are not designed to mimic stream-typical conditions. Relatively little is known on exposure and effect assessment using stream mesocosms.
Thus the present thesis evaluates the appliacability of the stream mesocosms to mimic stream-typical pulse exposures, to assess resulting effects on flora and fauna and to evaluate aquatic-terrestrial food web coupling. The first objective was to mimic stream-typical pulse exposure scenarios with different durations (≤ 1 to ≥ 24 hours). These exposure scenarios established using a fluorescence tracer were the methodological basis for the effect assessment of an herbicide and an insecticide. In order to evaluate the applicability of stream mesocosms for regulatory purposes, the second objective was to assess effects on two aquatic macrophytes following a 24-h pulse exposure with the herbicide iofensulfuron-sodium (1, 3, 10 and 30 µg/L; n = 3). Growth inhibition of up to 66 and 45% was observed for the total shoot length of Myriophyllum spicatum and Elodea canadensis, respectively. Recovery of this endpoint could be demonstrated within 42 days for both macrophytes. The third objective was to assess effects on structural and functional endpoints following a 6-h pulse exposure of the pyrethroid ether etofenprox (0.05, 0.5 and 5 µg/L; n = 4). The most sensitive structural (abundance of Cloeon simile) and functional (feeding rates of Asellus aquaticus) endpoint revealed significant effects at 0.05 µg/L etofenprox. This concentration was below field-measured etofenprox concentrations and thus suggests that pulse exposures adversely affect invertebrate populations and ecosystem functions in streams. Such pollutions of streams may also result in decreased emergence of aquatic insects and potentially lead to an insect-mediated transfer of pollutants to adjacent food webs. Test systems capable to assess aquatic-terrestrial effects are not yet integrated in mesocosm approaches but might be of interest for substances with bioaccumulation potential. Here, the fourth part provides an aquatic-terrestrial model ecosystem capable to assess cross-ecosystem effects. Information on the riparian food web such as the contribution of aquatic (up to 71%) and terrestrial (up to 29%) insect prey to the diet of the riparian spider Tetragnatha extensa was assessed via stable isotope ratios (δ13C and δ15N). Thus, the present thesis provides the methodological basis to assess aquatic-terrestrial pollutant transfer and effects on the riparian food web.
Overall the results of this thesis indicate, that stream mesocosms can be used to mimic stream-typical pulse exposures of pesticides, to assess resulting effects on macrophytes and invertebrates within prospective environmental risk assessment (ERA) and to evaluate changes in riparian food webs.
The work presented in this thesis investigated interactions of selected biophysical processes that affect zooplankton ecology at smaller scales. In this endeavour, the extent of changes in swimming behaviour and fluid disturbances produced by swimming Daphnia in response to changing physical environments were quantified. In the first research question addressed within this context, size and energetics of hydrodynamic trails produced by Daphnia swimming in non-stratified still waters were characterized and quantified as a function of organisms’ size and their swimming patterns.
The results revealed that neither size nor the swimming pattern of Daphnia affects the width of induced trails or dissipation rates. Nevertheless, as the size and swimming velocity of the organisms increased, trail volume increased in proportional to the cubic power of Reynolds number, and the biggest trail volume was about 500 times the body volume of the largest daphnids. Larger spatial extent of fluid perturbation and prolonged period to decay caused by bigger trail volumes would play a significant role in zooplankton ecology, e.g. increasing the risk of predation.
The study also found that increased trail volume brought about significantly enhanced total dissipated power at higher Reynolds number, and the magnitudes of total dissipated power observed varied in the range of (1.3-10)X10-9 W.
Furthermore, this study provided strong evidence that swimming speed of Daphnia and total dissipated power in Daphnia trails exceeded those of some other selected zooplankton species.
In recognizing turbulence as an intrinsic environmental perturbation in aquatic habitats, this thesis also examined the response of Daphnia to a range of turbulence flows, which correspond to turbu-lence levels that zooplankton generally encounter in their habitats. Results indicated that within the range of turbulent intensities to which the Daphnia are likely to be exposed in their natural habitats, increasing turbulence compelled the organisms to enhance their swimming activity and swim-ming speed. However, as the turbulence increased to extremely high values (10-4 m2s-3), Daphnia began to withdraw from their active swimming behaviour. Findings of this work also demonstrated that the threshold level of turbulence at which animals start to alleviate from largely active swimming is about 10-6 m2s-3. The study further illustrated that during the intermediate range of turbu-lence; 10-7 - 10-6 m2s-3, kinetic energy dissipation rates in the vicinity of the organisms is consistently one order of magnitude higher than that of the background turbulent flow.
Swarming, a common conspicuous behavioural trait observed in many zooplankton species, is considered to play a significant role in defining freshwater ecology of their habitats from food exploitation, mate encountering to avoiding predators through hydrodynamic flow structures produced by them, therefore, this thesis also investigated implications of Daphnia swarms at varied abundance & swarm densities on their swimming kinematics and induced flow field.
The results showed that Daphnia aggregated in swarms with swarm densities of (1.1-2.3)x103 L-1, which exceeded the abundance densities by two orders of magnitude (i.e. 1.7 - 6.7 L-1). The estimated swarm volume decreased from 52 cm3 to 6.5 cm3, and the mean neighbouring distance dropped from 9.9 to 6.4 body lengths. The findings of this work also showed that mean swimming trajectories were primarily horizontal concentric circles around the light source. Mean flow speeds found to be one order of magnitude lower than the corresponding swimming speeds of Daphnia. Furthermore, this study provided evidences that the flow fields produced by swarming Daphnia differed considerably between unidirectional vortex swarming and bidirectional swimming at low and high abundances respectively.
Increasingly, problematic smartphone use behavior (PSU) and excessive consumption are reported. In this study, an experiment was developed to investigate the influence of screen coloration using the grayscale setting on smartphone usage time in repeated measurements. We also investigated how individuals perceived suffering correlates with smartphone usage time and PSU, and whether differences exist by smartphone usage type (social, process, habitual). 240 subjects completed a questionnaire about smartphone usage time, PSU, perceived suffering, and smartphone usage types. Afterward, their smartphones were switched to grayscale setting for at least 24h, and thereafter 92 of these participants completed the second questionnaire. Analyses showed that grayscale setting decreases usage time and that there is a positive correlation between PSU, smartphone usage duration, and perceived suffering. The types of use (process and habitual) influence one’s perceived suffering. Thus, it shows that individuals are aware of their PSU and suffer from it. Using grayscale setting is effective in reducing smartphone use time.
Über 10.000 verschiedene organische Substanzen wie Arzneistoffe, Inhaltsstoffe von Körperpflegemitteln und Biozide werden regelmäßig im Alltag eingesetzt. Die meisten Substanzen gelangen nach ihrer Verwendung in das häusliche Abwasser. Bisherige wissenschaftliche Untersuchungen haben ergeben, dass eine konventionelle biologische Abwasserreinigung in kommunalen Kläranlagen keine ausreichende Barriere für die Emission dieser anthropogenen Stoffe in die Oberflächengewässer darstellt.
Dies birgt unvorhersehbare Risiken für die aquatischen Lebensgemeinschaften und die Trinkwasserversorgung. Hinsichtlich ihres Vorkommens und Verhaltens in kommunalen Kläranlagen besteht daher insbesondere für erst kürzlich eingeführte und/oder in der Umwelt nachgewiesene Spurenstoffe (sogenannte "neuartige" Spurenstoffe, engl.: "emerging micropollutants") ein großer Forschungsbedarf. Um ein möglichst umfassendes Bild vom Verhalten neuartiger organischer Spurenstoffe in der kommunalen Abwasserbehandlung zu erhalten, wurden im Rahmen dieser Dissertation die folgenden Substanzklassen, welche ein weites Spektrum an physiko-chemischen Eigenschaften aufweisen, untersucht: Arzneistoffe (Betablocker und psychoaktive Substanzen), UV-Filtersubstanzen, Vulkanisationsbeschleuniger (Benzothiazole), Biozide (Antischuppenmittel, Konservierungsmittel, Desinfektionsmittel) und Pestizide (Phenylharnstoff- und Triazinherbizide).
Generalized methods for automated theorem proving can be used to compute formula transformations such as projection elimination and knowledge compilation. We present a framework based on clausal tableaux suited for such tasks. These tableaux are characterized independently of particular construction methods, but important features of empirically successful methods are taken into account, especially dependency directed backjumping and branch local operation. As an instance of that framework an adaption of DPLL is described. We show that knowledge compilation methods can be essentially improved by weaving projection elimination partially into the compilation phase.
The decline of biodiversity can be observed worldwide and its consequences are alarming. It is therefore crucial that nature must be protected and, where possible, restored. A wide variety of different project options are possible. Yet in the context of limited availability of resources, the selection of the most efficient measures is increasingly important. For this purpose, there is still a lack of information. This pertains, as outlined in the next paragraph, in particular, to information at different scales of projects.
Firstly, there is a lack of information on the concrete added value of biodiversity protection projects. Secondly, there is a lack of information on the actual impacts of such projects and on the costs and benefits associated with a project. Finally, there is a lack of information on the links between the design of a project, the associated framework conditions and the perception of specific impacts. This paper addresses this knowledge gap by providing more information on the three scales by means of three empirical studies on three different biodiversity protection projects in order to help optimize future projects.
The first study “Assessing the trade-offs in more nature-friendly mosquito control in the Upper Rhine region” examines the added value of a more nature-friendly mosquito control in the Upper Rhine Valley of Germany using a contingent valuation method. Recent studies show that the widely used biocide Bti, which is used as the main mosquito control agent in many parts of the world, has more negative effects on nature than previously expected. However, it is not yet clear whether the population supports a more nature-friendly mosquito control, as such an adaptation could potentially lead to higher nuisance. This study attempts to answer this question by assessing the willingness to pay for an adapted mosquito control strategy that reduces the use of Bti, while maintaining nuisance protection within settlements. The results show that the majority of the surveyed population attaches a high value to a more nature-friendly mosquito control and is willing to accept a higher nuisance outside of the villages.
The second study “Inner city river restoration projects: the role of project components for acceptance” examines the acceptance of a river restoration project in Rhineland-Palatinate, Germany. Despite much effort, many rivers worldwide are still in poor condition. Therefore, a rapid implementation of river restoration projects is of great importance. In this context, acceptance by society plays a fundamental role, however, the factors determining such acceptance are still poorly understood. In particular, the complex interplay between the acceptance or rejection of specific project components and the acceptance of the overall project require further exploration. This study addresses this knowledge gap by assessing the acceptance of the project, its various ecological and social components, and the perception of real and fictitious costs as well as the benefits of the components. Our findings demonstrate that while acceptance of the overall project is generally rather high, many respondents reject one or more of the project's components. Complementary social project components, like a playground, find less support than purely ecological components. Overall, our research shows that complementary components may increase or decrease acceptance of the overall project. We, furthermore, found that differences in the acceptance of the individual components depend on individual concerns, such as perceived flood risk, construction costs, expected noise and littering as well as the quality of communication, attachment to the site, and the age of the respondents.
The third study “What determines preferences for semi-natural habitats in agrarian landscapes? A choice-modelling approach across two countries using attributes characterizing vegetation” investigates people's aesthetic preferences for semi-natural habitats in agricultural landscapes. The EU-Common Agricultural Policy promotes the introduction of woody and grassy semi-natural habitats (SNH) in agricultural landscapes. While the benefits of these structures in terms of regulating ecosystem services are already well understood, the effects of SNH on visual landscape quality is still not clear. This study investigates the factors determining people’s visual preferences in the context of grassy and woody SNH elements in Swiss and Hungarian landscapes using picture-based choice experiments. The results suggest that respondents’ choices strongly depend on specific vegetation characteristics that appear and disappear over the year. In particular, flowers as a source of colours and green vegetation as well as ordered structure and the proportion of uncovered soil in the picture play an important role regarding respondents’ aesthetic perceptions of the pictures.
The three empirical studies can help to make future projects in the study areas of biodiversity protection more efficient. While this thesis highlights the importance of exploring biodiversity protection projects at different scales, further analyses of the different scales of biodiversity protection projects are needed to provide a sound basis to develop guidance on identifying the most efficient biodiversity protection projects.
Thousands of chemicals from daily use are being discharged from civilization into the water cycle via different pathways. Ingredients of personal care products, detergents, pharmaceuticals, pesticides, and industrial chemicals thus find their way into the aquatic ecosystems and may cause adverse impacts on the ecology. Pharmaceuticals for instance, represent a central group of anthropogenic chemicals, because of their designed potency to interfere with physiological functions in organisms. Ecotoxicological effects from pharmaceutical burden have been verified in the past. Therapeutic groups with pronounced endocrine disrupting potentials such as steroid hormones gain increasing focus in environmental research as it was reported that they cause endocrine disruption in aquatic organisms even when exposed to environmentally relevant concentrations. This thesis considers the comprehensive investigation of the occurrence of corticosteroids and progestogens in wastewater treatment plant (WWTP) effluents and surface waters as well as the elucidation of the fate and biodegradability of these steroid families during activated sludge treatment. For the first goal of the thesis, a robust and highly sensitive analytical method based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed in order to simultaneously determine the occurrence of around 60 mineralocorticoids, glucocorticoids and progestogens in the aquatic environment. A special focus was set to the compound selection due to the diversity of marketed synthetic steroids. Some analytical challenges have been approved by individual approaches regarding sensitivity enhancement and compound stabilities. These results may be important for further research in environmental analysis of steroid hormones. Reliable and low quantification limits are the perquisite for the determination of corticosteroids and progestogens at relevant concentrations due to low consumption volumes and simultaneously low effect-based trigger values. Achieved quantification limits for all target analytes ranged between 0.02 ng/L and 0.5 ng/L in surface water and 0.05 ng/L to 5 ng/L in WWTP effluents. This sensitivity enabled the detection of three mineralocorticoids, 23 glucocorticoids and 10 progestogens within the sampling campaign around Germany. Many of them were detected for the first time in the environment, particularly in Germany and the EU. To the best of our knowledge, this in-depth steroid screening provided a good overview of single steroid burden and allowed for the identification of predominantly steroids of each steroid
type analyzed for the first time. The frequent detection of highly potent synthetic steroids (e.g. triamcinolone acetonide, clobetasol propionate, betamethasone valerate, dienogest, cyproterone acetate) highlighted insufficient removal during conventional Summary wastewater treatment and indicated the need for regulation to control their emission since the steroid concentrations were found to be above the reported effect-based trigger values for biota. Overall, the study revealed reliable environmental data of poorly or even not analyzed steroids. The results complement the existing knowledge in this field but also providednew information which can beused particularly for compound prioritization in ecotoxicological research and environmental analysis. Based on the data obtained from the monitoring campaign, incubation experiments were conducted to enable the comparison of the biodegradability and transformation processes in activated sludge treatment for structure-related steroids under aerobic and standardized experimental conditions. The compounds were accurately selected to cover manifold structural moieties of commonly used glucocorticoids, including non-halogenated and halogenated steroids, their mono- and diesters, and several acetonide-type steroids. This approach allowed for a structure-based interpretation of the results. The obtained biodegradation rate constants suggested large variations in the biodegradability (half-lifes ranged from < 0.5 h to > 14 d). An increasing stability was identified in the order from non-halogenated steroids (e.g. hydrocortisone), over 9α-halogenated steroids (e.g. betamethasone), to C17-monoesters (e.g. betamethasone 17-valerate, clobetasol propionate), and finally to acetonides (e.g. triamcinolone acetonide), thus suggesting a strong relationship of the biodegradability with the glucocorticoid structure. Some explanations for this behavior have been received by identifying the transformation products (TPs) and elucidating individual transformation pathways. The results revealed the identification of the likelihood of transformation reactions depending on the chemical steroid structure for the first time. Among the identified TPs, the carboxylates (e.g. TPs of fluticasone propionate, triamcinolone acetonide) have been shown persistency in the subsequent incubation experiments. The newly identified TPs furthermore were frequently detected in the effluents of full-scale wastewater treatment plants. These findings emphasized i) the transferability of the lab-scale degradation experiments to real world and that ii) insufficient removals may cause adverse effects in the aquatic environment due to the ability of the precursor steroids and TPs to interact with the endocrine system in biota. For the last goal, the conceptual study for glucocorticoids was applied to progestogens.
Here, two sub-types of the steroid family frequently used for hormonal contraception were selected (17α-hydroxyprogesterone and 19-norstestosterone type). The progestogens showed a fast and complete degradation within six hours, and thus empathizes pronounced biodegradability. However, cyproterone acetate and dienogest Summary have been found to be more recalcitrant in activated sludge treatment. This was consistent with their ubiquitously occurrence during the previous monitoring campaign. The elucidation of TPs again revealed some crucial information regarding the observed behavior and highlighted furthermore the formation of hazardous TPs. It was shown that 19-nortestosterone type steroids are able to undergo aromatization at ring A in contact with activated sludge, leading to the formation of estrogen-like TPs with a phenolic moiety at ring A. In the case of norethisterone the formation of 17α-ethinylestradiol was confirmed, which is a well-known potent synthetic estrogen with elevated ecotoxicological potency. Thus, the results indicated for the very first time an unknown source of estrogenic compounds, particularly for 17α-ethinylestradiol. In conclusion, some steroids were found to be very stable in activated sludge treatment, others degrade well, and others which do degrade but predominantly to active TPs depending on their chemical structure. Fluorinated acetal steroids such as triamcinolone acetonide and fluocinolone acetonide are poorly biodegradable, which is reflected in high concentrations detected ubiquitously in WWTP effluents. Endogenous steroids and their most related synthetic once such as hydrocortisone, prednisolone or 17α-hydroxyprogesterone are readily biodegradable. Regardless their high influent concentrations, they are almost completely removed in conventional WWTPs. Steroids between this range have been found to form elevated quantities of TPs which are partially still active, which particularly the case for betamethasone, fluticasone propionate, cyproterone acetate or dienogest. The thesis illustrates the need for an extensive evaluation of the environmental risks and carried out that corticosteroids and progestogens merit more attention in environmental regulatory and research than it is currently the case
Instructor feedback on written assignments is one of the most important elements in the writing process, especially for students writing in English as a foreign language. However, students are often critical of both the amount and quality of the feedback they receive. In order to better understand what makes feedback effective, this study explored the nature of students’ assessments of the educational alliance, and how their receptivity to, perceptions of, and decisions about using their instructors’ feedback differed depending on how strong they believed the educational alliance to be. This exploratory case study found that students not only assessed the quality of the educational alliance based on goal compatibility, task relevance, and teacher effectiveness, but that there was also a reciprocal relationship between these elements. Furthermore, students’ perceptions of the educational alliance directly influenced how they perceived the feedback, which made the instructor’s choice of feedback method largely irrelevant. Stronger educational alliances resulted in higher instances of critical engagement, intrinsic motivation, and feelings of self-efficacy. The multidirectional influence of goal, task, and bond mean that instructors who want to maximize their feedback efforts need to attend to all three.
Die heutige Landwirtschaft ist in hohem Maße auf den Einsatz von Pestiziden angewiesen, um verschiedene Schädlinge zu bekämpfen und die Ernteerträge zu maximieren. Trotz detaillierter Vorschriften für den Einsatz von Pestiziden, die auf einem komplexen System der Risikobewertung beruhen, hat sich gezeigt, dass der weit verbreitete Einsatz dieser biologisch aktiven Substanzen eine Gefahr für die Umwelt darstellt. In Oberflächengewässern wurde beobachtet, dass die Pestizidbelastung die als noch umweltverträglich angesehenen Konzentrationen übersteigt und sich negativ auf die Ökologie der Fließgewässer auswirkt, was die Frage aufwirft, ob die derzeitige Risikobewertung einen nachhaltigen Einsatz von Pestiziden gewährleistet. Um diese Frage zu beantworten, hat das umfassende "Kleingewässer-Monitoring" (KgM) in den Jahren 2018 und 2019 das Vorkommen von Pestiziden und die damit verbundenen ökologischen Auswirkungen in 124 Fließgewässern in ganz Deutschland untersucht.
Basierend auf fünf wissenschaftlichen Publikationen, die aus dem KgM hervorgegangen sind, werden in dieser Arbeit die Pestizidbelastung in Fließgewässern, die ökologischen Auswirkungen und die regulatorischen Implikationen bewertet. Mehr als 1000 Wasserproben wurden auf über 100 Pestizid-Analyten untersucht, um das Vorkommen zu charakterisieren (Publikation 1). Die gemessenen Konzentrationen und Auswirkungen wurden zur Validierung der in der Risikobewertung vorhergesagten Umweltkonzentrationen und Wirkungschwellen verwendet (Veröffentlichung 2). Durch die gemeinsame Analyse von realen Pestizidanwendungsdaten und gemessenen Pestizidmischungen in Fließgewässern wurde die Missachtung von Pestizidmischungen in der Umwelt in der Risikobewertung beurteilt (Veröffentlichung 3). Das Risikopotenzial von Mischungen in Fließgewässern wurde zusätzlich mit Hilfe eines Verdachtsscreenings für 395 Chemikalien und einer Batterie von In-vitro-Bioassays untersucht (Publikation 4). Schließlich wurden die Ergebnisse des KgM verwendet, um die Eignung staatlicher Monitoringprogramme zur Identifizierung von Pestizidrisiken in Oberflächengewässern zu bewerten (Publikation 5).
Die Ergebnisse dieser Arbeit zeigen das weit verbreitete Vorkommen von Pestiziden in den Nichtzielökosystemen der Fließgewässer. Die Wasserproben wiesen eine Vielzahl von Pestiziden auf, die in komplexen Mischungen vor allem in kurzzeitigen Spitzenwerten nach Niederschlagsereignissen auftraten (Veröffentlichungen 1 & 4). Die jeweiligen Höchstwerte der Pestizidkonzentration wurden mit dem Rückgang empfindlicher Wirbellosenarten in Verbindung gebracht und überstiegen in etwa 80 % der landwirtschaftlich geprägten Fließgewässer die gesetzlich zulässigen Konzentrationen, welche als Schwellenwerte zum Teil noch als unzureichend für den Schutz der Wirbellosengemeinschaft angesehen wurden (Publikation 2). Das gleichzeitige Vorkommen von Pestiziden in Fließgewässern führte zu einem Risiko, das in der auf eine einzelne Substanzen ausgerichteten Risikobewertung in realistischen Worst-Case-Szenarien um einen Faktor von etwa 3,2 unterschätzt wurde. Dies wird durch die hohe Häufigkeit, mit der Nichtzielorganismen den Pestiziden ausgesetzt sind, weiter verstärkt (Veröffentlichung 3). Wasserproben, die nach Regenfällen entnommen wurden, verursachten in den Bioassays deutliche Effekte, die nur zu einem geringen Teil durch die vielen detektierten Analyten erklärbar waren, was auf die Relevanz unbekannter chemischer oder biologischer Mischungskomponenten hinweist (Publikation 4). Schließlich wurde festgestellt, dass die behördliche Überwachung von Oberflächengewässern gemäß der Wasserrahmenrichtlinie (WRRL) die Risiken von Pestiziden erheblich unterschätzt, da hier etwa drei Viertel der kritischen Pestizide und mehr als die Hälfte der gefährdeten Gewässer übersehen worden wären (Veröffentlichung 5).
Im Wesentlichen liefert diese Arbeit eine neue Ebene der Validierung der Risikobewertung von Pestiziden in aquatischen Ökosystemen, indem das Auftreten von Pestiziden und ihre Auswirkungen auf die Umwelt in einem bisher einzigartigen Maßstab bewertet werden. Die Ergebnisse zeigen generell, dass der derzeitige landwirtschaftliche Einsatz von Pestiziden zu erheblichen Auswirkungen auf die Fließgewässerökologie führt, die über das von der Risikobewertung tolerierte Maß hinausgehen. In dieser Arbeit wurden die Unterschätzung der Pestizidexposition, die potenzielle Unzulänglichkeit der gesetzlichen Schwellenwerte und die allgemeine Trägheit des Zulassungsverfahrens als Hauptursachen dafür ermittelt, dass entsprechende gesetzlich verankerte, ökologische Zielsetzungen momentan erwiesenermaßen nicht erreicht werden. Um einen nachhaltigen Einsatz von Pestiziden zu gewährleisten, schlägt die Arbeit wesentliche Änderungen der Risikobewertung vor. Monitoringprogramme wie das KgM, die über die derzeitigen staatlichen Überwachungsbemühungen hinausgehen, werden weiterhin erforderlich sein, um die Regulierungsbehörden für Pestizide ständig über die Gültigkeit ihrer prospektiven Risikobewertung zu informieren, die immer mit Unsicherheiten behaftet sein wird.
