Environmental exposure assessment tools and models:

Eurometaux and ARCHE have developed this tool to help DU check compliance with the ES for the environmental compartments (aquatic compartments, sediments, soil, sewage treatment plant and local air concentrations). Key operational conditions and risk managements measures can be selected that represent the site-specific conditions of the DU site.

ARCHE has developed this tool for calculating site-specific ecological risk of metals in soil. Key soil properties (such as pH, Organic matter, clay content and cation exchange capacity) are required to calculate a site-specific soil PNEC. Further guidance is provided in the tool. 

  • Freshwater PNEC calculator : 

The freshwater PNEC calculator is still under development by NiPERA, ARCHE, WCA and Alchamy Consulting. Key water parameters such as dissolved organic matter, pH and hardness are required to calculated a site-specific PNEC for freshwater. Further guidance will be provided in the tool.  Untill the tool is available, please contact for more information

Eurometaux and ARCHE have developed default specific environmental release factors to air and wastewater which are meant to replace the more conservative environmental release categories (ERCs) developed by ECHA. They are available for several production and use processes, and can be selected within the Downstream user Scaling Tool for estimating environmental exposure. 

ARCHE has developed the GPM tool for estimating local air concentrations to neighbouring populations. This tool takes into account more site-specific information and replaces the more conservative estimates from the DU scaling tool. More information is provided within the tool and an example of using it is provided in the nickel specific guidance for Man via the Environment.


Human Health exposure assessment tools and models:

Eurometaux and EBRC Consulting developed this tool for estimating worker exposure to metals and inorganics. Site-specific operational conditions and risk management measures can be selected to estimate exposure via the dermal and inhalation routes.
