The consumption of pharmaceutical compounds has been rising
considerably in the last years, due to several reasons, such as the
population growth and the inverting age structure, as well as the
appearance of new target age groups, the discovery of new drugs or
of new uses for existing ones (Khetan and Collins, 2007). Consequently,
the risk of water contamination with these chemicals has
increased. Pharmaceuticals and their metabolites can enter the
environment via several routes, illustrated in Fig. 1.
