DU SCALING TOOL
Under REACH, the Downstream User (DU) is obliged to check compliance with the Exposure Scenario (ES) forwarded by the Registrant. The information on Operational Conditions (OCs) and Risk Management Measures (RMMs) given in the ES should be compared with the actual OCs and RMMs of the DU. OCs/RMMs may not always be completely identical with the OCs/RMMs specified in the ES, and may actually deviate from them. When one or more of the actual OC and RMM differ from those of the ES, it is not immediately apparent whether the use is still in compliance with the ES. In all cases, the DU should still be able to ascertain that he is in compliance with the ES.
For this situation, the registrant can provide scaling rules as part of the ES to help DUs to check compliance with the ES and to increase the flexibility of ESs for a wider range of downstream users. EUROMETAUX and ARCHE have developed a DU scaling tool (originally initiated by EURAS) for compliance checking with the environmental ES of metals. The DU scaling tool is based on the spreadsheet version of EUSES. This tool is freely available for industry,other entities that provided the necessary data to develop the tool and governmental organizations.
In the registrant-interface, the generic default OCs and RMMs can be entered. Some of them are very relevant for metals, such as the possibility to provide measured regional concentrations and solid-water partition coefficients.
In the simple and easy-to-use DU-interface, key OC and RMM can be changed according to the site-specific OC and RMMs of the DU. This includes general parameters as release factors, dilution, presence/absence of municipal sewage treatment plant, etc... It also allows the DU to enter bioavailability-corrected PNECs (Predicted No Effect Concentrations), for those metals for which relevant models are available.
In the background, the full EUSES model is run to calculate exposure and risks.
The resulting risk characterisation ratios allow the DU to assess safe use. In this way, the DU scaling tool enables the DU to check compliance with the ES if his OCs or RMMs differ from those in the ES.
How does it work?
In the ES scaling tool sheet, the metal of concern should be selected. This will automatically fill out several metal-specific parameters such as regional concentrations, PNECs and solid-water partition coefficients. Key OC and RMM can be changed according to the site-specific OC and RMMs of the DU. This includes general parameters as release factors, dilution, presence/absence of municipal sewage treatment plant, etc…, In the advanced mode (by clicking on plus buttons on the left, the DU can enter monitoring data or bioavailability-corrected PNECs (Predicted No Effect Concentrations), for those metals for which relevant models are available.In the background, the full EUSES model is run to calculate exposure and risks. The resulting risk characterisation ratios allow the DU to assess safe use. In this way, the DU scaling tool enables the DU to check compliance with the ES if his OCs or RMMs differ from those in the ES.Please consult EUROMETAUX’s guidance on ES for DU-mmies for more information of ES compliance checking.
- The tool is available for download and own use for EUROMETAUX members, other entities that provided the necessary data to develop the tool and associated downstream users. Governmental organizations can also get access. There is a version for Excel 2007 (extension xlsx).
- If your metal is not available in the background database please contact your metal consortium.
- Any feedback is highly appreciated (please send your comments to Dr Frederik Verdonck at email@example.com mentioning the operating system and office/excel version, thanks!!).

ARCHE has become a certified Cradle to Cradle Material Health Assessor
Given today’s demands for more socially and environmentally conscious products and materials, it is important for companies to positively define their global impact and be leaders in environmental performance. In that regard, we proudly announce that ARCHE has been certified by the Cradle to Cradle Products Innovation Institute as un authorized Cradle to Cradle Material Health Assessor.
EU new BIOCIDAL Products Regulation (BPR) applies from September first!
ARCHE together with its strategic partner ReachCentrum has set up a service focusing in particular to support those companies looking for an authorisation of biocidal products/approval of active substances under the new BPR regulation whether it is for an application of authorisation on EU level or for one on national level.
ARCHE launches its RESCUE program!
ARCHE developed a one-to-one assistance program to help downstream users demonstrate compliance with their extended safety data sheets they get from their supplier.
New Soil PNEC calculator is available!
A new updated version of the soil PNEC calculator is available for download on our website. Apart from a new layout, this new version now also includes data for Co and Mo. All calculations are now based on the data and methods selected for the EU REACH dossiers (Registration, Evaluation, Authorisation and Restriction of Chemicals; Regulation EC No 1907/2006) for Cu, Ni, Zn, Pb, Cd, Mo and Co, as available in August 2012."
SPERC tool for metals is updated!
The first version of the metal SPERCs was published in 2010 for the purpose of the 2010 REACH registration deadline and underwent a review process conducted by Lüskow et al. (2011) on behalf of the Federal Environment Agency of Germany (UBA). The second version of the metal SPERCs were improved based on the recommendations by Lüskow et al. (2011) and Tolls et al. (in press) and were further updated with new data for the purpose of the 2013 REACH registration deadline. This second version is currently undergoing a scientific review process but can already been find on this website.
