In the present EU regulation for plastic materials and articles intended
to come into contact with food (EU, 2011) S is listed without
any restriction. Especially no Specific Migration Limit (SML) is
defined; consequently the overall migration limit of 60 mg/kg food
would apply. In 2003, WHO (2003) published a Tolerable Daily Intake
(TDI) of 7.7 lg/kg bw/d, corresponding to 0.46 mg/person/d
(based on 60 kg body weight).
