A fast and simple method for determination of B, Al, Cr, Mn, Ni, Co,
Cu, Zn, As, Se, Sr, Cd, Sb, Ba, Hg, and Pb in toys by laser ablation
inductively coupled plasma mass spectrometry (LA-ICP-MS) has been
developed. Using 
as an internal standard and self-made
polyethylene-based materials containing multi-element as an external
standard, high sensitivity, and stable accuracy of both standard
reference materials and real samples have been gained by the method.
The detection limits (MDLs) of 16 elements ranged from 0.011 to
6.56mg/kg, and the corresponding precisions of these elements ranged
from 3.5% to 9% (n = 8). The linear ranges of the calibration curves
are over two orders of magnitudes. This method has been applied to the
quick quantification of 16 toxic and hazardous elements required by EU
toy directive (2009/48/EC) [2]. Most of these elements were detected
at concentration levels ranging from 4.2 to 249mg/kg and from 13.9 to
254mg/kg in paint coating (wood toys) and in polyurethane leather (toy
models), respectively.
