OBJECTIVES FOR LOT 3  • 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  14  15  Draft proposal for a European Partnership under Horizon Europe, Partnership for the Assessment of Risk from  Chemicals (PARC).
