MODELKEY - The key to clean surface waters

28.02.2005


Analysing and evaluating chemical pollution – that is the goal of the new European large-scale project MODELKEY, starting in February. Under the management of the Centre for Environmental Research Leipzig-Halle, Germany (UFZ) researchers in 13 countries will be developing methods to identify so-called key chemicals and their effect on the water ecosystem until the year 2010. Three model rivers will be researched from their source to the mouth: River Elbe (Czech Republic/ Germany), River Schelde (Belgium/ The Netherlands), and River Llobregat (Spain). These three rivers are situated in different climate regions and all suffer from industrial pollution. The findings will later be passed on to all EU member states. The project, involving a total of 25 different research institutions, is subsidised with 8.4 million Euro by the EU. The name of the project, MODELKEY, stands for Models for Assessing and Forecasting the Impact of Environmental Key Pollutants on Marine and Freshwater Ecosystems and Biodiversity. The kick-off for MODELKEY will take place from 28th February to 5th March in Spain.

Background:

The EU Water Framework Directive (WFD) has committed all states to see that their surface waters are in good chemical and ecological condition by the year 2015. The goal of the guidelines is to create common standards for surface and groundwater. In this way pollution should be stemmed and the condition of the ecosystem improved in order to protect the water resources in the long-term. The Water Framework Directive has divided the ecological water quality into five grades from bad to very good. By 2015 all surface waters should be of at least grade II (good status). In particular many ecosystems in industrialised regions of Europe have not reached the “good” status. Although the chemical parameters in Germany more or less fulfil the requirements, the Ministry of the Environment sees large deficits in the biological parameters. The job of the MODELKEY project is to find the causes of these problems and develop solutions for them.



Even though the EU has made a priority list of 30 chemicals which are monitored already, the scientists see a need for a much greater field of research. “When you think that there are thousands of different chemical combinations in the environment then it is clear: The current grid is just too wide,” explains Werner Brack from UFZ. “That is why we are trying to combine biological and chemical processes as well as different model techniques so that the spectrum on possible problems can be narrowed down step by step, and to finally identify every connection that really is responsible for harmful effects.” The complete ecosystem will be considered. Do changes to an individual organism affect the whole ecosystem? What does it mean for the ecosystem, when for example a particular fish stops reproducing? These are complex questions which have to be answered by 2010.

The preparation of the long-term project alone took two years. Partners had to be found and a structure had to be created. Michaela Hein and Mechthild Schmitt coordinate seven sub-projects and over 150 researchers under the lead of Werner Brack. “We have to develop new innovative techniques in all fields,” Brack paraphrases the coming project. “The challenge is to combine different scientific roots.”

The international research team does not just want to find these key pollutants and explain their effect. The huge volume of data from the surface water control programme from the EU member states are to be put to use. “At the moment the data are stored in different databases in various formats and are therefore extremely difficult to handle. That is why we want to create a central database – working closely with the ministries who today collect data and who will later have to implement the EU Water Framework Directive.” Finally a computer model is to be developed which will offer support to the water authorities in the whole EU when decisions must be made about which area should be decontaminated and how it can be done most effectively. One thing is clear: The EU Water Framework Directive means a lot of extra work for the individual member countries.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
