Assessing Nanoparticle Toxicity in Waste Water
Nanoparticle Tracking Analysis (NTA) has found use in a variety of investigations researching the toxicity and environmental impact of nanoparticles. Here we discuss various publications in which NTA has been used to measure particle size and concentration of nanomaterials in waste water.

Introduction
Increasing interest in – and rapid development of – a wide range of materials and products containing nanoscale structures and engineered nanoparticles has been accompanied by a greater awareness that the longer term potential toxic effects of such materials and their potential environmental impact are poorly understood. Existing methods have been assessed and new methods sought by which such materials could be analyzed on a routine basis during development and manufacture.
The use of Nanoparticle Tracking Analysis as a rapid and information-rich multi-parameter nanoparticle characterization technique which allows the user to obtain number frequency particle size distributions of polydisperse nanoparticulate systems has resulted in its rapid adoption as an interesting new technique in a wide range of sectors within environmental and toxicity studies. This white paper addresses some of the latest work in the literature in which NTA has been proposed, used and assessed in the study of nanoparticle toxicity and environmental impact.
