In aquatic systems and even in the human body, pharmaceuticals are modified by environmental stressors which subsequently change the exposure scenario (Oskarsson et al., 2014). Although individual pharmaceuticals are used in very small quantities (therapeutic dose), the presence of several similar pharmaceuticals (sharing same mode
