The aim of this work was to monitor the migration of di-2-ethylhexyl phthalate (DEHP) and di-n-octyl phthalate (DOP) from polyvinyl chloride (PVC) toys into artificial saliva under conditions that mimic the chewing of a toy by a child when he puts the toy in his mouth - temperature 37°C and shaking in an ultrasonic bath. The obtained results show an insignificant percentage of the migration of the mentioned phthalates in artificial saliva, the values of the percentage of DEHP migration are from 0.0025 to 0.0051%, while for DOP the mass percentage are from 0.0003 to 0.0009%. These results are due to the fact that DEHP and DOP are non-polar compounds, voluminous structures, and as such do not tend to transfer to a polar environment such as artificial saliva. However, one should be concerned, because this research determined migration only in a certain period of time, while in real conditions, the child repeatedly puts the same toy in the mouth, and is contaminated with phthalates every day during early childhood, which certainly has a negative effect on his development.
