Abstract: A recent analysis (Pohjola MV et al, Food and Chemical Toxicology 50 (2012) 40–55) concluded that there are emerging tendencies in environmental health assessments: (a) increasing engagement between assessment and management as well as stakeholders, (b) strive for framing assessments according to specific practical policy needs, (c) integration of multiple benefits and risks, as well as (d) explicit incorporation of both scientific facts and value statements in assessment.

Open exposure data is one key aspect in the development of open, engaging assessments. However, there are major development needs to fully utilise the potential of open exposure data, including:

1) Standardised but flexible systems to upload and store data.
2) Straightforward methods to implement data in assessment models and policy analyses.
3) Tools to comment data (or other parts) used in assessments.
4) Implement all of these functionalities using a single, user-friendly, open web workspace.

We built a web workspace Opasnet ( that especially addresses these four developmental needs. Its development started from EU-funded projects BENERIS, INTARESE, and HEIMTSA. Opasnet has a user interface that is based on a wiki, and it has several additional functionalities. It has a very flexible database for storing small or large datasets and modelled results. It has statistical software R attached to it; code can be edited on and run from a wiki page, with fast and simple access to all stored data. It also has flexible functionalities to analyse and display data on a web page, including a Google map interface for GIS data. Commenting of the content is organised on wiki pages and has specific rules.

Although there are several data repository projects going on, we are not aware of another project that attempts to solve all these needs at the same time.

The whole workspace is open source code and open data, and anyone can build on the current functionalities.
