Occurence and environmental properties of antibiotics in organic waste. Effects and bioaccumulation in Crustaceans

Project Details


Medical substances such as antibiotics have been used intensively in agriculture and exposed to the environment with very little attnsion. In this project an environmental risk assesment is performed involving analyses of 10 different antibiotics and their metabolites in organic wastes; investigations of degradation is soil and water, transport in the environment including leaching and effect and accumulation analysis on algae and daphnids.

As test objects are selected 10 different antibiotics representing different groups of action. Besides they represent the groups used in the highest quantities in Danish farming.

In the present part of the project is focused on effects and bioaccumulation in the freshwater crustacean Daphnia magna. Acute (immobilisation) tests and reproduction tests are performed and accumulation studies are planned.
