Environmental behaviour of pharmaceuticals
The presence of active pharmaceutical ingredients (API) in the environment has been a growing concern in recent years. Around 2300 different API are being administered, and it is estimated that more than 8 000 t of drugs are being consumed - annually alone in Germany. 1200 of these pharmaceuticals are considered environmentally relevant since they are Persistent, Bioaccumulative or Toxic (PBT). So far 150 different API have been detected in waste water effluents, in surface water, ground water and drinking water in Germany. Even though the concentrations are very low (ng/L to µg/L) they may cause a threat not only to aquatic and terrestrial organisms but also to human health. Together with the University of Gdańsk and the group of Prof. Piotr Stepnowski we are investigating the environmental behaviour of several different types of drugs such as antibiotics, anti-diabetics, anthelmintics, beta-blockers, anti-inflammatoy drugs and contraceptives. Thereby we address various research topics:
- development of analytical methods
- ecotoxicity assessment of pharmaceuticals, their mixtures and their transformation products
- abiotic and biotic degradability under various environmental conditions
- elucidation of degradation pathways
- waste water treatment
