International symposium on aminophosphonates and the environment

Aminophosphonates - We use them every day. Whether in detergents, dishwashing detergents, cosmetics or shampoos, without phosphonates these products would lose quality and, above all, their performance. But what happens to them after use? Do they harm the environment?

At the international symposium on "Aminophosphonates and the environment", researchers from Europe, Asia, the USA, Canada and other countries will present the latest scientific findings on the environmental behavior of aminophosphonates. The English-language event is aimed at an interested specialist audience from science, politics and society.

Under the direction of Prof. Martienssen, the Chair of Biotechnology of Water Treatment has been working on the abiotic and biological degradation of phosphonates for more than ten years. The aim of the investigations is to clarify their environmental behavior and to derive predictions about their fate in the environment. In addition to the photochemical investigations, the Chair is conducting intensive research into the development and standardization of a new test procedure for determining the biodegradability of aminophosphonates. This test system for different microorganisms (i.e. pure cultures, mixed cultures or activated sludge from a wide range of wastewater treatment plants) is intended to determine biodegradability on the one hand and the influence of structural changes on biodegradation on the other quickly and reliably.
