The priority organic pollutants are known to reach the sewer system through sewage from human activities,
atmospheric deposition on the soil, urban runoff and industrial emissions. During wastewater treatment, they
tend to accumulatein WWS duetotheir non polar and hydrophobic naturethat favour adsorption ontosuspended
solids and organic matter. Scrimshaw and Lester (2003) presented a list of the most abundant endocrine
disrupter compounds in WWS in which NPs, NPEOs, phthalates (e.g. DEHP), PAHs, BPA and PCBs came to the
fore with concentrationsover 10 mg kg-1.Their fate during wastewater treatment is also determined bychemical
and biological degradation and volatilization. Development of WWS treatment or value added processes shall
consider removal of these priority organic pollutants because they are closely related to WWS beneficial uses
