The scientific objectives of this project are:

1.To create a tiered screening system for identifying potential PBTs and POPs amongst existing chemicals;
2.To verify whether the potential PBTs / POPs identified in the screening program are present in the European background environment / the remote Arctic;
3.To evaluate the efficacy of the tiered screening system for identifying PBTs and POPs.

The broader objective of the project is to contribute to increased safety in the use of chemicals and to foster society’s acceptance of chemicals by providing a novel and effective tool to identify chemicals that could be deleterious to the environment or human health.
