In order to demonstrate compliance with article 3 of the Framework Regulation (EC)No 1935/2004, the following must be considered:- By defining the end use application(s) of the coating, it may be possible toestimate a limit of migration equating to an exposure of < 1.5 µg/person/day. Inthis case, the reaction product does not deserve any further toxicologicalevaluation 1 . This process may utilise probabilistic modelling for exposureassessments 2 .- If the level of 1.5 µg/person/day is exceeded, then it is necessary to apply otherconsiderations using universally recognised techniques, such as SAR(Structural Activity Alerts) and Kramer classes for toxicological thresholds whereif the structure of a substance is broadly known, higher levels of migration maynot require toxicological testing of that substance.12See ILSI Monographs, ‘Threshold of Toxicological concern for chemical substances present in thediet, report of a workshop held in October 1999’ Anon August 2000 and ‘Threshold of toxicologicalconcern (TTC) – a tool for assessing substances of unknown toxicity present at low levels in thediet’ S. Barlow July 2005.Further information is contained in I. C. Munro, J. J. Hlywka, E. M. Kennepohl - Risk assessmentof packaging materials, Food Additives and Contaminants 19, Proceedings Supplement 3-12,2002.Industry has asked the Commission for an opinion on the suitability of probabilistic modelling forassessing exposure to migrants from food packaging materials. Examples of the use ofprobabilistic modelling for assessing exposure to migrants from food packaging may be obtainedfrom the following:ILSI Monograph ‘Exposure from food contact materials.
