## OBJECTIVES FOR LOT 3 

<img src='content_image/485982.jpg'>

• Development of roadmap for action on the risk assessment of combined exposure to multiple chemicals (RACEMiC) 

The main objective  of the roadmap for action for this lot is to develop and implement a harmonised approach for the assessment of human health risks resulting from both dietary and non-dietary exposure to multiple chemicals. Th e following objectives should be read alongside the theme paper on t he risk assessment of combined exposure to multiple chemicals (RACEMiC) ( Annex 5 ). 

The specific objectives for lot 3 are: 

## Objective 1: Refining the problem formulation proposed in the offer 

i) Provide a refined problem formulation for the routine implementation of human health risk assessment of combined dietary and non-dietary exposure to multiple chemicals across EFSA’s domains of activity . This includes a refinement of the scope and objectives described in the theme paper (Annex 5) focusing on: 

a) methods development, tools harmonisation, data consolidation and implementation; 

b) a stepwise implementation, starting with the routine risk assessment of dietary exposure to multiple pesticides, the subsequent integration of non- dietary exposure to pesticides, and ultimately the extension to other chemicals; 

ii) Provide a refined workplan (milestones, timelines, etc) describing and potentially refining the methodology proposed in the offer and that will be used to achieve all subsequent objectives (2-7). 

## Objective 2: Mapping relevant activities and organisations for combined exposure to multiple chemicals 

i) Map all relevant ongoing and planned activities related to the human health risk assessment of combined exposure to multiple chemicals (including research projects and innovation programmes of regulatory relevance for human health risk assessment, associated timelines and the organisations responsible for/involved in these projects/programmes), at national level, European level and international level. As a minimum, the mapping should include the EC, EU Member States’ national bodies , relevant EU Agencies (e.g. ECHA, EEA, EMA, etc) and relevant EU institutions and their work programmes (e.g. the JRC and Horizon 2020 and Horizon Europe, in particular PARC 15 ), as well as in international organisations (e.g. U.S. FDA, U.S. EPA, OECD and those listed in
