Department of Aquatic Sciences and Assessment

We develop knowledge about environmental changes and their causes through research, education, and environmental analysis. The department takes a broad and interdisciplinary approach to water issues, focusing on monitoring, understanding, and contributing to improved quality in Sweden’s aquatic environments.

Education

If you are interested in delving deeper into water-related issues, welcome to explore our information on courses at undergraduate, advanced, and research levels we are involved in. Also, we offer a certification course for water sampling.

Research

Our research concerns everyone in Sweden, as water is a vital resource that affects everything from our health and food production to biodiversity and climate adaptation.

Environmental analysis

Environmental analysis of freshwater provides long-term data series from our lakes and watercourses. This is crucial for making well-informed decisions on the management, protection, and sustainable use of our water resources.

Microplastics impact aquatic environments

Microplastics are long-lasting. They are found everywhere. They can move within and between different environments, and they can affect both soil- and water-dwelling organisms. In this short film, you’ll meet Kong and Mareile, whose research focuses on microplastics in aquatic environments and in soil.
