Evaluation of 1000+ substances, species and sites is hampered by incomplete and incompatible data. Hence human and ecological risk assessment often relies on simple models such as SIMPLEBOX and OMEGA. We have learned that our work is used by a diverse set of stakeholders, in particular

- students, researchers

- policymakers, manager, consultants, regulators

- press, general public

interested in chemical pollution.

While we address both SIMPLEBOX and OMEGA, the focus is on the latter.
