【 摘 要 】

however, analyses of smaller sized (<50 nm) TiO2 NPs and mixtures of different sized NPs were unreliable. Ten of the consumer products contained nanosized Ag particles, and eight of the consumer products contained nanosized TiO2 particles. The number of Ag NPs and TiO2 NPs in consumer products was over a hundred thousand. The results obtained from the analyses of consumer spray products could be applied to exposure assessments of consumer products. With further method validation, the SP-ICP-MS method could characterize the particle size and particle number concentration of diverse samples.
