NORMAN Prioritisation framework for emerging substances -Passive sampling interlaboratory study - data evaluation

To this purpose the NORMAN Working Group on “Prioritisation of emerging substances” was set up in 2010 to develop a prioritisation scheme designed for emerging substances and associated knowledge gaps. The NORMAN scheme is addressed to water managers and competent authorities that are aiming to identify priority substances at national, river basin and European level. It provides decision-makers with a common framework for the creation and updating of the lists of chemical substances for which actions to reduce, monitor or gather scientific or technical data are to be undertaken as a matter of priority. This document will be updated according to the latest scientific findings whenever those are available.
