Abstract

Phthalates has been widely used in children’s toys as plastic plasti­ci­zers and softeners. Therefore, attention should be paid to plastic toys, espe­cially those that children can put in their mouths. In this paper quantification of five phtha­lates: DMP, DnBP, BBP, DEHP and DnOP in plastic toys, as well as irradiation of toys with UV light was performed. After sample preparation and development of the liquid–liquid phthalate extraction method from artificial saliva phthalate quanti­tative determination using the GC–MS technique was performed. The mean re­covery value for DEHP is 77.03±2.76 %. The deter­mination of phthalate in the recipient models (artificial saliva and n-hexane) was performed after 6, 15 and 30 days of the migration test using the GC–MS technique. Based on the known mass % DEHP in the analyzed toys, the per­centage of phthalate migration from each analyzed toy to the recipient model after 6, 15 and 30 days of the migration test was calculated. The results show that there is no significant mig­ration of DEHP into artificial saliva, due to high polarity of the recipient (arti­ficial saliva is polar), unlike n-hexane where the migration of DEHP is significant because it is a non-polar solvent.
