Rhine samples

Delft Scientists have been the first to link the presence of pharmaceutical residues in the Rhine to the demographic characteristics of people living along this river. This knowledge could be used to develop a better way of dealing with the contamination of drinking water. Professor Nick van de Giesen and Dr. Rolf Hut of CEG faculty and Corine Houtman from the Water Laboratory published their findings in December in Environmental Research Letters. “Young people and the elderly use very different pharmaceuticals in different quantities. Pharmaceutical usage also varies by nationality. These differences are so great that we were indeed able to detect most of these pharmaceuticals in the river water”, explains Hut.
