Specialized maps with expert content (Nmet) implementing the contract No. 201301009 dated 16 December 2014. The presented set of maps includes the series of studies on various components of the environment. Overall, the results from seven studies are included, four of them are focused on aquatic environment, and two of them are focused on outdoor and one of them on indoor environment. Four studies bring the data about potential biological effects in environmental mixtures from four different aquatic ecosystems. In maps the data of water contamination (sampled also using passive samplers) and sediment contamination are included as the most important monitored matrices for the occurrence of emergent pollutants. 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.
