Environmental Chemistry



Environmental Chemistry is dedicated to fundamental and applied research in environmental toxicology and chemistry. The overall aim is to gain scientific knowledge that can strongly contribute to the identification, quantification, and decision-making in relation to environmental problems caused by emissions of existing and emerging chemical contaminants from the technosphere to the environment.

Scientific topics in focus:

  • Microplastics in the Environment
  • Exposure & Chemodynamics of contaminants
  • Chemical fate modelling
  • Ecotoxicity& Risk assessment
  • Regulatory engineering
  • Nanomaterials in the environment
  • Partitioning-based approaches

Chemical fate modelling

Prediction of the fate and behavior of chemicals in the environment is feasible with mathematical models that integrate physical, chemical and biological process. Our focus is on plant uptake and bioaccumulation.

Regulatory engineering

Regulation involves complex environmental, social and ethical considerations. Regulatory engineering focuses on the development of decision-support frameworks and principles making better use of engineering in regulatory settings. Focus is on regulation of chemicals and nanomaterials.


Development of new test principles and methods for providing information on ecotoxicity which is one of the cornerstones in environmental risk assessment. We are specialized in algal, crustacean and plant tests, and in testing of poorly soluble chemicals and other difficult to test chemicals.

Project Examples

Microplastics in the aquatic environment

Plastic litter is a cause of increasing environmental concern. Microplastics are today ubiquitous in surface waters and aquatic organisms is known to ingest these plastic particles. Our focus is on occurence and sources, mechanisms of particle behaviour in the water, the interaction with other pollutants and with organisms.

Partitioning-based approaches

Partitioning based approaches are applied in research on processes, exposure and effects of organic chemicals in the environment. Partitioning into polymers is used for enrich-ment and measurements at utra-trace levels. The section is internationally leading the development of passive dosing.

Nanomaterials in the environment

The increasing use of nanomaterials in society makes it crucial to understand their environmental behavior and effects. Advanced physical-chemical characterization, models and laboratory experiments provide a base for increase scientific insight and regulatory decision-support.
