Erik Andresen
Erik Andresen is head of the section at NILU dealing with inorganic analyses. He is educated in chemical engineering at Sofienberg Technical College. Erik started in NILU's inorganic laboratory in 1989 as a chemical technician.
Erik has knowledge and experience with all the analysis methods. In 2007, he was hired as operations manager for his department. He was then employed as an engineer. The job involved customer contact, ordering analyses and reporting the analysis results to the customers.
Erik has been involved in starting up laboratories in five different countries. The job involves quality control of the analysis results before they are sent out to customers. Erik has a lot of experience in the following fields: analyses of cations and anions using ion chromatography, pH measurements in precipitation, analyses of precipitation dust, gravimetrically determination of PM2.5 and PM10 on filters, as well as determination of NO2, SO2 and NH3 using passive samplers.
Helene Lunder Halvorsen
Dr Helene Lunder Halvorsen is a scientist at the Department of Environmental Chemistry and Health Effects and responsible for the Norwegian monitoring programme "Atmospheric contaminants" on behalf of the Norwegian Environment Agency. She is also involved in the reporting of organic contaminants under the European Monitoring and Evaluation Programme EMEP.
She has a master's degree in Organic Chemistry (MSc) and completed her PhD at the Department of Chemistry at the University of Oslo in 2023. In her PhD, she focused on regulated persistent organic pollutants (POPs) and used air samples from Norway and Europe to investigate the occurrence, distribution and sources of POPs.
During her 13 years at NILU, she has gained much experience with air sampling and analysis of organic contaminants, with a particular focus on method development and quality assurance of data.
Mikael Harju
Dr. Mikael Harju's core competence lies in environmental analytical chemistry, with a main focus on studying and reducing organic pollutants in Arctic and sub-Arctic ecosystems.
As a researcher at NILU in Tromsø, he is driven by a desire to develop advanced, reliable methods for detection, quantification and assessment of persistent organic pollutants (POPs) and new environmental pollutants. His work is specifically aimed at understanding how these pollutants interact with biotic and abiotic components of vulnerable ecosystems, where cold climates and unique ecological factors can influence how the pollutants are dispersed and decomposed.
Throughout his career, he has specialized in improving analytical methods for sensitive matrices, such as fish and other biological material, to deliver data that is essential for environmental monitoring and risk assessments. His goal is not only to improve analytical precision, but also to contribute to public health and environmental policy through sound science. He is motivated by the opportunity to combine applied chemistry with ecosystem conservation efforts, and to protect these important areas and their communities from long-term pollution problems.
Nina Elisabeth Dahl
Nina Dahl is a laboratory coordinator and purchasing manager at the Department of Environmental Chemistry and Health Effects, at the Inorganic Section. She has worked at Nilu since 1991 in the same department.
Nina Dahl is responsible for:
- Registration of incoming samples.
- Purchasing and accounting.
- Completion of passive samplers.
- Safety delegate tasks.
Dahl has been involved in many of the tasks at Inorganic, and now works mostly administratively.
She finds motivation in the great collegial environment and her inspiring tasks.
Ingjerd Sunde Krogseth
Dr. Ingjerd S. Krogseth is a senior scientist in the Department of Environmental Chemistry and Health Effects at NILU, as well as an adjunct professor at UiT – The Arctic University of Norway. She is located in the Fram Centre in Tromsø.
Krogseth conducts research on how organic contaminants behave in the environment and food chains, motivated by a desire to protect the environment, ecosystems, and humans from harmful compounds. She is particularly interested in new environmental contaminants that are still unregulated, in order to contribute to a sound scientific basis for decision-making for national and international environmental authorities. Another focus area is how ongoing climate change affects the fate of organic contaminants in the environment and ecosystems.
Krogseth works extensively with the development, evaluation and application of contaminant models for ecosystems and food chains. These models are used in combination with actual measurements from the environment to understand more about how the contaminants are transported to and end up in organisms and food chains. She is particularly interested in organic contaminants in Arctic ecosystems, and she works closely with biologists and ecotoxicologists at other institutions in the Fram Centre through the Fram Centre's research programmes.
