[Preliminary investigation on endocrine disrupting chemicals in a sewage treatment plant of Beijing].
Endocrine disrupting chemicals (EDCs) existed in the water treatment units of Beijing based Sewage Treatment Plant were analyzed by SPE-GC/MSD and GC/ECD. Totally 30 EDCs were detected from the influent, effluent and sludge. The results show that about 70%-99% EDCs in the influent were removed after treatment. Sludge adsorption played an important role in the reduction of EDCs. The range of phenols in sludge was 17-35 mg/kg, the range of PAEs was 25-77 mg/kg and the range of PAHs was 1.33-1.74 mg/kg. Compared with the results in other countries in literature, the existence of EDCs in the Sewage Treatment Plant was not serious.
