Column experiment with trace organic compounds and benthic organisms

This video shows a column experiment simulating bank filtration to investigate the effects of benthic organisms (Nuttall's waterweed and Quagga mussels) on trace organic compounds. In this video Anna Lena Kronsbein from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) explains the principle of her column experiment and how column sampling, e.g. oxygen measurements, is carried out.
