occurrence, removal and environmental risk assessment
Περιγραφή
In the present work, an extensive study on the presence of eighteen pharmaceuticals and personal care products
(PPCPs) in eight wastewater treatment plants (WWTPs) of Greece has been conducted. The study covered four
sampling periods over 1-year, where samples (influents; effluents) from eight WWTPs of various cities in Greece
were taken. All WWTPs investigated are equipped with conventional activated sludge treatment. A common pre concentration step based on SPE was applied, followed by LC–UV/Vis–ESI–MS. Further confirmation of positive
findings was accomplished by using LC coupled to a high resolution Orbitrap mass spectrometer. The results
showed the occurrence of all target compounds in the wastewater samples with concentrations up to
96.65 μg/L. Paracetamol, caffeine, trimethoprim, sulfamethoxazole, carbamazepine, diclofenac and salicylic acid
were the dominant compounds, while tolfenamic acid, fenofibrate and simvastatin were the less frequently
detected compounds with concentrations in effluents below the LOQ. The removal efficiencies showed that
many WWTPs were unable to effectively remove most of the PPCPs investigated. Finally, the study provides an
assessment of the environmental risk posed by their presence in wastewaters by means of the risk quotient
(RQ). RQs were more than unity for various compounds in the effluents expressing possible threat for the aquatic
environment. Triclosan was found to be the most critical compound in terms of contribution and environmental
risk, concluding that it should be seriously considered as a candidate for regulatory monitoring and prioritization
on a European scale on the basis of realistic PNECs. The results of the extensive monitoring study contributed to a
better insight on PPCPs in Greece and their presence in influent and effluent wastewaters. Furthermore, the unequivocal identification of two transformation products of trimethoprim in real wastewaters by using the advantages of the LTQ Orbitrap capabilities provides information that should be taken into consideration in future
PPCP monitoring studies in wastewaters.
