Sensors and Analytic

The group dealing with Chemical Sensors and Analytics investigates nutrient cycles and behavior of lake ecosystems and small wetlands. We perform systems analysis in terms of nutrient budgets, fluxes between compartments and transformations. We investigate processes at interfaces with high temporal and/or spatial resolution applying in situ measuring and sampling systems.

• The Yangtze River in China, third longest river in the world, is also said to be the most polluted. In a recent report of UNEP the Yangtze estuary at Shanghai was declared as ‘dead’. Analyzing 300 chemical substances in 30 samples collected on a stretch of 1600 km between the Three Gorges Dam at Yichang and the mouth at Shanghai will allow a pollutant mapping and may allow a characterization of the habitat of the now extinct White River Dolphin.
