The measurement and characterization of nanoparticles in the environmental and biological samples are essential to understand the fate, behavior, and potential toxicity of nanoparticles. Single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) is a promising technique that has the potential to determined particle size, number concentration, and aggregataion state in environmental samples at environmentally relevant low concentrations (ng/L) . The samples containing particles in a short period of time (dwell time) can be analyzed by SP-ICP-MS and converted to the particle number-based size and concentrations . It was applied to predict the aggregation structure of nanoparticles in water samples. The mass of an aggregates measured by SP-ICP-MS calculated the number of the primary(single) nanoparticle in an aggregates. The dispersed nanoparticles in the environmental waters (e.g., tap water, river water, and municipal waste waters) and biological tissues (e.g., chicken breast and Daphnia) were also determined by measuring mass concentrations and nano range sizes.
