DESCRIPTION OF THE ACTION
The detection of emerging contaminants such as antibiotics and pesticides in the environment can be highly
challenging as they typically occur in the environment at very low levels (Kostopoulou and Nikolaou, 2008).
Additionally, for many of them, reference standards, which are needed to validate the analytical methods, are not
