Interlaboratory studies

Building the capacity of laboratories in Europe and globally by systematic organisation and initiation of international Collaborative Trials is part of the regular activities of the NORMAN network. More than 20 Collaborative Trials have been organised by NORMAN since 2006 on a wide range of methods, including non-target screening in water, sediment, indoor dust and biota, in vitro and in vivo bioassays and passive sampling. Based on the needs identified by the NORMAN community, these studies represent a crucial step for the scientific community and for environmental agencies for validation and harmonisation of innovative sampling and monitoring tools before their possible future implementation in regulations.
