We present recent results that provide an understanding for the chemical speciation of nanoparticles and the associated environmental health and safety issues. We refer to the ‘chemical speciation of nanoparticles’ as the distribution of the nanoparticles and their corresponding components (i.e. atomic or molecular components, or surrounding stabilizers) by transformation due to changes in the environment (air, water, soil). The project is motivated by the increase in the manufacture and use of nanoparticles in consumer products and the need for a consensus on their analysis. The increase in nanoparticles' usage continues to raise concerns for the adverse impacts on the environment and on human health. The interaction of nanoparticles with various environmental components must be assessed, and systematic analytical methods for doing so are required.
