“…As children typically spend a significant amount of time playing with toys, they are more susceptible to chemical hazards compared to adults, also due to their physiological and behavioral characteristics. 39,41,42 Growing concerns about the potential harmful effects of chemicals present in toys have prompted the development of several analytical methods, including atomic absorption spectrometry (AAS), 43 X-ray fluorescence (XRF), 8,14,44,45 gas chromatography (GC) coupled with flame ionization detection 6,7,34 or various mass spectrometers, 8,11,[15][16][17][18][19][20][21]27,44,46 and (ultra)high-performance liquid chromatography [(U)HPLC] combined with ultraviolet−visible detection, 8,31,47−49 fluorescence detection, 8,9 or different mass spectrometers. 8,10,25,44,48 Among these techniques, mass spectrometry (MS) has found wide applications in analytical laboratories owing to its high analysis sensitivity, specificity, and speed.…”
