Summary

A method for the analysis of 10 phthalate esters in plastic toys is described. The samples are soxhlet extracted in dichloromethane and phthalate esters in the extract are analysed by GC. Detection limits of dimethyl phthalate, diethyl phthalate, dibutyl phthalate, bis(2-ethylhexyl) phthalate, di-n-octyl phathalate, di-n-nonyl phthalate, benzyl butyl phthalate and benzyl octyl phthalate were approximately 5 ppm. The detection limits of diisononyl phthalate and diisodecyl phthalate, which are mixtures of several isomers, were approximately 200ppm. Analysis of 17 plastic toys revealed that only PVC-toys contained phthalate esters. Bis(2-ethylhexyl) phthalate, diisononyl phthalate and diisodecyl phthalate in concentrations up to 40% were present in the PVC-toys.
