71 micropollutants have been monitored in raw, digested, centrifuged, thermally dried sludge and sludge cakes from Paris. First data about micropollutants in sludge liquor from dewatering treatments are published. LAS (0.1–10g/kg DM), DEHP (10–100 mg/kg DM) and fluoroquinolones (1–100 mg/kg DM) have high contents in sludge. Hormones, perfluorinated acids and several pharmaceuticals are found below 1 mg/kg DM in sludge. Most pollutants are found in sludge liquor from dewatering treatments, at comparable concentrations than wastewater.
