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.
