A new category of substances, Pharmaceutical Active Compounds (PhACs), has been detected in different parts of integrated urban wastewater and stormwater (IUWS) systems. PhACs are characterized by different fate processes compared to those included in existing MP (MicroPollutants) fate modelling libraries. Thus, existing modelling tools cannot predict the fate of PhACs, and it is not possible to estimate the human and environmental risk due to their discharge in natural water. In this work a dynamic model library was developed to enable the simulation of PhACs across different IUWS elements (sewers, wastewater treatment plants, receiving water bodies). The model performance was assessed by simulating the fate of four PhACs in two different IUWS systems, where measurements were available. Model prediction capability was good, highlighting how the model can be a valuable support tool for a sustainable management of water in urban areas.

Abstract
A new category of substances, Pharmaceutical Active Compounds (PhACs), has been detected in different parts of integrated urban wastewater and stormwater (IUWS) systems. PhACs are characterized by different fate processes compared to those included in existing MP (MicroPollutants) fate modelling libraries. Thus, existing modelling tools cannot predict the fate of PhACs, and it is not possible to estimate the human and environmental risk due to their discharge in natural water. In this work a dynamic model library was developed to enable the simulation of PhACs across different IUWS elements (sewers, wastewater treatment plants, receiving water bodies). The model performance was assessed by simulating the fate of four PhACs in two different IUWS systems, where measurements were available. Model prediction capability was good, highlighting how the model can be a valuable support tool for a sustainable management of water in urban areas.| File | Dimensione | Formato | |
