“…[13][14][15][16] The quantitative techniques used for the determination of Pb mainly include inductively coupled plasma optical emission spectrometry (ICP-OES), 17 inductively coupled plasma atomic emission spectrometry (ICP-AES), 18 inductively coupled plasma mass spectrometry (ICP-MS), 5 ame atomic absorption spectrometry (F-AAS), 19,20 and graphite furnace atomic absorption spectrometry. 21 Several methods have been described for the determination of As such as hydride generation atomic absorption spectrometry (HG-AAS), 22 ICP-OES 17 and ICP-MS. 23 Additionally, instrumental neutron activation analysis (INAA) 24 can be applied in the direct analysis of solid cosmetics thereby avoiding laborious sample preparation processes.…”
