Exposure routes of chemical compounds from soil into plants need to be known to assess the risk of food contamination. Each EU member state so far uses or develops own assessment methods. This is inefficient and may lead to non-optimal solutions. An expression of interest was sent to the EC, proposing an initiative within the 6th EU framework programme, which aims at harmonizing the assessment methods for the transfer of chemicals into food. Existing and new methods shall be evaluated and compared in close accordance with the administrative needs. Gaps of knowledge will be identified and filled. An assessment tool (multilingual) for the EU member states based on the best available knowledge will be implemented and made available.
