(например, остаточных мономеров в полимере), которые могли бы мигрировать в контактную среду (напр., в воду или продукты питания)

См., например:

There are many substances of toxicological interest, restricted for plastic materials and
articles intended to come into contact with foodstuffs. These are restricted trough the SML
and QM (maximum permitted quantity of the residual substance in the material or article
expressed as mg per dm2 of the surface in contact with foodstuffs). SML “is applied to
individual authorised substances and is fixed on the basis of the toxicological evaluation of the substance. The SML is generally established according to the acceptable daily intake (ADI) or the tolerable daily intake (TDI) set by the Scientific Committee on Food (SCF). To set the limit, it is assumed that, every day throughout his/her lifetime, a person of 60 kg eats 1 kg of food packed in plastics containing the relevant substance at the maximum permitted quantity”.
