Description: Das Projekt "Photokatalytischer Abbau von Cyanotoxinen und Pathogenen in Trinkwasser" wird vom Umweltbundesamt gefördert und von Institut für Solarenergieforschung GmbH durchgeführt. Objective/Problems to be solved: Water is becoming an increasingly scarce resource throughout the world and furthermore, many of these limited supplies have become nutrient enriched, supporting the growth of toxic cyanobacteria. These organisms produce extremely toxic naturally occurring compounds that frequently cause the death of both wild and domestic animals via ingestion of contaminated water. The death of patients undergoing dialysis has also been reported as a result of water used in their treatment being contaminated with the cyanotoxin microcystin-LR. In recognition of the potential risk to human health posed by cyanotoxins the World Health Organisation has now established a maximum limit of 1 Ag l-1 of microcystin-LR in drinking water. Cyanotoxins are very stable and traditional water treatment processes will not destroy them. There is also growing concern over contamination of water by pathogenic bacteria including E. coli O157 that has been associated with a number of high profile health incidents. The proposed revised Drinking Water Directive 98/83/EC will characterise high priority water pollutants. Toxin-producing algae have been specifically highlighted as a potential key hazardous pollutant. It has been identified that work needs to be carried out in developing expertise on these species and how to deal with them in drinking water. The new directive will also include a requirement to verify the efficiency of disinfection. This research proposal includes the development of such a device on the water treatment unit: The European Commission Task Force on Environment-Water identified 10 priority areas (so called 'action lines') for EU collaborative research and development in the area of freshwater. Action line 3 specifically highlights toxin-producing algae as a potential key hazardous pollutant and identified that work needs to be carried out developing expertise on these species and how to deal with them in drinking water. It also specifically mentions inadequate treatment of drinking water as being a potential problem. Action line 4 details the requirement to develop water treatment technologies for, among other things, the disinfection of drinking water. Photocatalytic oxidation is an advanced water treatment sub-technology specifically identified as an area where research should be concentrated. Scientific objectives and approach: The problems of contamination of drinking water by cyanotoxins and E. coli will be investigated using semiconductor photocatalysis. The objective of this project is to develop a method primarily for dealing with cyanotoxins in drinking water. In addition the destruction of the pathogenic micro-organism, E. coli, will also be investigated. A novel biosensor will be developed for the on-line detection of cyanotoxins in water... Prime Contractor: The Robert Gordon Unversity, School of Mechanical and Offshore Engineering; Aberdeen/Scotland.
