The rapid increase in both the numbers of different engineered nanoparticles and in their overall production prompts concerns about their fate.

Nanoparticles from industrial processes and consumer products are inevitably found in river and seawater. Their potential to accumulate in biological organisms and their inherent toxicological potential are of widespread concern.

Scrutiny of the environmental fate of engineered nanoparticles begins with detection and here Malvern’s NanoSight range performs well. Particles in suspension down to 10nm, dependent on their nature, can be detected, sized and counted. Nanoparticle Tracking Analysis (NTA) provides these measurements in robust and practical formats which are applied widely.
