    Aquatic Ecotoxicology (Department of Freshwater and Marine Ecology, IBED, UvA)

    The mission of my research line (Aquatic Ecotoxicology) is to assess, monitor and predict the responses of benthic invertebrates to complex environmental changes. Progressively increasing worldwide anthropogenic disturbances shift species to new environmentally defined boundaries. To what extend this leads to changes in community composition and ecosystem functioning depends critically on the ability of each species to cope with a changing environment. Why do some species persist under harsh conditions, where other species fail to maintain viable populations and get, at least locally, extinct? To answer this question benthic invertebrates are subjected to combinations of natural and man made stressors. Experiments typically last for several generations and responses are determined at the gene level (ecotoxicogenomics; genetic adaptation) up to the population and community level. Bridging ecotoxicology and environmental chemistry, the fate and effects of emerging compounds (N-heterocyclic PAC; flame retardants) are studied.

    Since 1992, this research line has generated 25 PhD theses (van der Meer, 2023; de Vries, 2021; van der Lee, 2020; De Baat, 2020; de Brouwer 2020, Dos Reis Oliveira; 2019; van Puijenbroek, 2019; Waaijers, 2014; Hunting, 2013; Loayza-Muro, 2013; Marinkovic, 2012; Oyoo-Okoth, 2012; Leon Paumen, 2009; Pieters, 2007; de Haas, 2004; Heugens, 2003; Leslie, 2003; Osano, 2002; Wiegman, 2002; van der Geest, 2001; Ivorra, 2000; Bleeker, 1999; Groenendijk, 1999; Stuijfzand, 1999; Kraak, 1992).

    Currently 10 PhD projects are running:

    • Mud matters: the significance of effect based sediment quality assessment. (Wieringa, from September 2016).
    • Combatting cyanobacteria with hydrogen peroxide. (Weenink, from 2016).

    Prof. Dr. J. Huisman - Professor Aquatic Microbial Ecology

     

    Prof. Dr. Ir. P.F.M. Verdonschot - Special chair Wetland Restoration Ecology

    Prof. dr. ir. P.(Piet) F.M. Verdonschot received his MSc in Biology (specialization populations/ecosystems) at the Wageningen Agricultural University in 1978. He defended his PhD study entitled ‘Ecological characterization of surface waters in the province of Overijssel (The Netherlands)’ in 1990 at the Wageningen Agricultural University. He holds a special chair in Wetland Restoration Ecoloy at IBED, University of Amterdam. His did research on especially smaller aquatic ecosystems such as streams and ditches, pools and small lakes. His focus is on wetland ecosystem structure and functioning and restoration ecology. He specialized in ecosystem typologies, community studies, assessment, monitoring, restoration,biodiversity, and water and nature development. He did several studies on water policy making, setting standards and societal interaction. He specialized in macro-invertebrates with special expertise on oligochaetes and biting insects. He is experienced with statistical techniques, especially multivariate analyses, in working with field experiments, mescosms and laboratory experimental approaches.

    Wetlands are defined as “landscape units of marshes, swamps and surface waters with stagnant or running water, fresh, brackish or salt. The special chair Wetland Restoration Ecology studies the recovery processes of degraded wetlands and on the creation of new wetlands. This is achieved by understanding the functioning of current, restored and newly created wetlands, their driving factors and processes and the biological responses. The study areas are operational landscapes like stream valleys, polders, marshes and swamps adjacent to surface waters. Wetland Restoration Ecology integrates different disciplines of ecology, like population biology (of key species in wetlands), biogeography (distribution patterns at different scales) and stress ecology (especially multistress conditions).

    Research

    In soil, the bioavailability of chemicals is highly dependent on their interaction with soil particles and the resulting concentrations in the soil pore water. Organisms may affect their exposure by the way they interact with the soil, with some organisms literally eating themselves through the soil while others just walk on it or feed on leaf litter. In soil, pollution rarely is restricted to single chemicals. And life in soil is dynamic, asking for a dynamic approach when assessing the bioaccumulation and effects of chemicals in soil organisms. Finally, effects on single species may have consequences for the soil community and its role in important ecological processes (ecosystem services) like decomposition and nutrient cycling. My research focuses on aspects like bioavailability, routes of exposure, toxicokinetics and toxicodynamics, and mixture toxicity, but also aims at addressing effects at different levels of biological organization. I am studying metals, pesticides, nanoparticles and microplastics, using earthworms, enchytraeids, springtails, oribatid mites and isopods as the test organisms. I am interested in the application of our results in the risk assessment of new and existing chemicals. In addition, I am interested in using ecotoxicological test methods for the effect-based assessment of (contaminated) soils and other substrates.

    Dr. H.G. van der Geest - Assistant Professor Benthic Ecoloy

    The mission of this research line is to understand the biocomplexity at the sediment water interface. This complexity arises from the multitude of biological, physical and chemical processes that sustain and modify benthic life formed by compact consortia of specialized micro-algae, bacteria and (burrowing) invertebrates. Individual organisms, populations of species and multi-trophic consortia depend on, interact with and adapt to a-biotic processes, such as diffusion of oxygen, and sedimentation of silt and detritus. Simultaneously, biota modifies also these processes through their activities and natural conditions are strongly modified by man-made perturbation. The sequestration of organic matter and nutrients in sediments - for example - is tightly bound to the activity of benthic organisms and a large variety of contaminants is being deposited and partly biologically degraded in sediments. Another key process - with important consequences for water clarity - is the partitioning of particles between the water phase and solid deposits. Communities of phototrophic and heterotrophic species co-act in the process of stabilization and transformation of materials.

     

    Dr. M.L. de Baat - Assistant Professor Water Quality & Ecotoxicology

    Milo de Baat is Assistant Professor in Water Quality & Ecotoxicology at the Department of Freshwater and Marine Ecology of the Institute for Biodiversity and Ecosystem Dynamics at the University of Amsterdam. He previously worked as a scientific researcher in the Chemical Water Quality & Health group at KWR Water Research Institute. Milo's research explores how chemical pollution affects the health of aquatic ecosystems. Water is essential to life, but the increasingly complex chemical burden that human activities impose on freshwater and marine environments negatively impacts the biodiversity and functioning of aquatic ecosystems and threatens the provision of clean and safe water for human use and consumption. By combining innovative sampling methods and effect-based toxicity assessment, Milo's research aims to unravel the complexity and toxic effects of chemical mixtures in the environment. By aligning these findings with knowledge of biodiversity and ecosystem functioning, he strives to quantify the limitations that chemical pollution imposes on environmental health in a variety of aquatic ecosystems.

     

    Antonia Praetorius - Assistant Professor Environmental Chemistry

    I am an assistant professor in Environmental Chemistry at the Department of Ecosystem & Landscape Dynamics (ELD) at the Institute for Biodiversity and Ecosystem Dynamics (IBED). Previously I worked as a Researcher at Stockholm University (Sweden) and as a Postdoc at the University of Vienna (Austria). I studied chemistry and obtained my PhD from ETH Zurich (Switzerland).

    My research interests centre around assessing the environmental fate of emerging chemical contaminants. I am particularly interested in understanding how the fundamental physical and chemical properties of a contaminant drive its transformation and transport behaviour in aquatic and terrestrial environments and how we can utilise this understanding to build models for predicting contaminant fate and concentrations. I have a strong expertise in particulate contaminants, such as engineered nanomaterials, nano- and microplastics and microfibers. Additionally, I am working on (persistent) organic contaminants, such as PFAS and (psycho)pharmaceuticals, as well as emerging contaminants in circular systems (such as wastewater reuse).  I very much enjoy working in interdisciplinary teams and I am convinced that addressing potential risks and designing effective mitigation strategies or regulations for emerging contaminants requires joint forces from different disciplines. 

    In our projects we combine modelling approaches with laboratory-based studies on contaminant fate processes (e.g. degradation/transformation, aggregation, sedimentation). We also work towards improving analytical methods for identifying emerging contaminants in different environmental matrices.
