PNEC-pro is now available online, free of charge (you only have to register for free). 
PNEC-pro does not replace generic environmental quality standards, but is used in higher-tier risk assessment following the guidelines of the Water Framework Directive. Usually, the results are used to further analyze the impact on aquatic communities on a geographical and temporal scale.

Scientific basis

The scientific basis of this tool is extensively studied in a research by Leiden University and Deltares. This has been published in a scientific paper written by  Verschoor, Vink, De Snoo and Vijver 2011.
We like to share our knowledge and make it available to a wide audience. PNEC-pro is an example of this.
