Specialized maps with expert content (Nmet) implementing the contract No. 201301009 dated 16 December 2014. The main topic of the set of maps is to visualize the information about the emergent pollutant occurrence in selected environmental components – aquatic and indoor environment, such as brominated flame retardants (especially polybrominated diphenylethers – PBDEs) and hexabromocyclododecane (HBCD), which were included in the Annexes of the Stockholm Convention on Persistent organic pollutants (POPs). Then, the data about occurrence of perfluorooctan sulfonate (PFOS), perfluorooctanoic acid (PFOA) and another perfluorinated compounds (PFCs) were obtained and visualized. Users of these results is not only professional public but also state and regional governments including the departments of Ministry of the Environment, which can use the results to fulfil the obligations of the Czech Republic in the framework of international conventions. Another target group of users are companies and institutions dealing with the quality and pollution of the indoor environment and aquatic ecosystem. In the Czech Republic it is especially health institutions, local governments, hygiene stations and companies responsible for the quality and hygienic condition of the buildings, as well as state companies of the Basin and Czech Hydrometeorological Institute. The methodology was certified on 22 December 2017 by the Ministry of the Environment and published in its Buletin 1/2017.
