The overall aim of this WP is to develop methods, protocols and an information base for converting information of exposures into quantitative estimates of health effect.

Specific objectives are thus to:

• develop a systematic methodology to assess exposure-response relationships for diverse environmental exposures such that the output can be linked to the valuation of health effects (WP1.4) and used as a basis for the policy assessments in SP3;
• apply the developed methodology to selected environmental exposures, relevant for the policy studies identified in SP3;
• identify gaps in the selected exposure–response relationships;
• resolve these gaps using existing data on exposure response relationships.
