DESCRIPTION:Prof. Urs Von Gunten\, Professor\, EAWAG - Swiss Federal Insti
 tute of Aquatic Science and Technology\, Dübendorf\, CH\nThe problem of m
 icropollutants in the aquatic environment is one of the big challenges of 
 the 21st century. With about 100’000 chemicals registered in the Europea
 n Union\, with 5000 of them produced in high quantities of > 100t/a\, it m
 ay not be astonishing that many of them are found in water resources\, was
 tewaters and drinking waters with modern analytical techniques. In the urb
 an water cycle\, there are several strategies\, such as (i) source control
 \, (ii) enhanced wastewater treatment and (iii) polishing drinking water t
 reatment to minimize the impact of chemicals in the aquatic environment an
 d for human health. One of the mitigation strategies for micropollutants i
 n water treatment consists of the application of oxidants. However\, with 
 typical oxidant doses applied in water treatment\, complete mineralization
  of micropollutants cannot be achieved and therefore knowledge on kinetics
  and mechanisms of the corresponding reactions is necessary. These studies
  can be combined with the measurement of toxicological endpoints to assess
  the overall gain of oxidation processes.\nThe lecture will provide an ove
 rview over the micropollutant problem in the urban water cycle and then fo
 cus on oxidative transformation processes of micropollutants including rea
 ction kinetics\, mechanisms and possibilities for toxicological assessment
