Abstract:
... With an increasing production and use of engineered nanoparticles (ENPs), inevitably grows their release into the environment. This makes it important to determine in what quantitates they occur in aquatic systems like seawater. However, even when using the most sensitive ICP-MS technique, quantification of very low seawater concentrations of ENPs is still concept rather than the fact. To approach ...
