Pesticide Pollution

Pesticides are chemicals used to control weeds, plant pathogens and insect pests. Pesticides can also be a key source of environmental problems within an ecosystem.


We study the future impact of pesticides using controlled laboratory and field trials, and we monitor environmental change through the Norwegian Agricultural Environmental Monitoring Program (JOVA). Our aim is to reduce pollution from point sources through development, optimization and promotion of specific measures like biofilters, and to use simulation models to develop risk assessment procedures and end-user tools for reducing diffuse pollution from pesticide spraying in different farming communities.

We primarily study the exposure to and the bioavailability of pesticides and degradation products in the environment. To progress our research, we continuously develop analytical methods for detecting new substances and in lower concentrations.
It is important that we publish the results of our research through channels and in formats that can be used by government agencies, advisory bodies, professional users and the public.

Our key aim is to increase the knowledge of pesticide transport, exposure, effects and risks in the environment under different climate and soil conditions, and develop recommendations for sustainable use of pesticides under Norwegian conditions. We initiate and participate in national and international research project to achieve this.

Our research activities focus on the degradation, sorption and transport of pesticides and their degradation products in the environment via laboratory and field trials. We also study industrial chemicals and bioactive natural substances.

Field trials that investigate pesticide fate in the environment and mitigation measures to reduce pesticide pollution form a key element of our activities. Field data is used to validate models and simulate the potential exposure concentrations of these substances and the resulting risks to health and the environment, based on site-specific information such as cultivation practices, climate, soil type and topography. Web-based end-user tools for pesticide risk assessment are developed to promote site specific assessment and enable the farmers in choosing pesticide strategies with the least environmental impact as part of their integrated pest management.

Research on the intersection between biotechnology and ecotoxicology is a focus area that is currently evolving.

Chemical analyzes are generally performed using modern instrumentation, and we continuously develop and optimize new and existing methods of analysis. Flexible accreditation and chemical analytical expertise facilitate the development of new methods and accredited analyses for research projects.

Our research-based teaching and guidance for students nationally and internationally at Master and PhD level, is mainly based on trials in the field, in laboratories and in greenhouses.
