This study involves 12 participants (from the US, Norway, and the Netherlands) that will contribute to the study voluntarily.


The main objective of this study is to map the state of the art in passive sampling sediments and to investigate which measures we can take to reduce any inter-method and -laboratory variation, in order to increase confidence in the use of passive sampling and to advance its use outside the scientific domain. A carefully designed study will identify sources of existing variation and means to reduce the variation, with the aim to provide recommendations and practical guidance for specific passive sampling formats.
