Hospital waste water: health risk for human and environment by cytostatic drug emissions? Part I: Model calculation and chemical monitoring
BMC Pharmacology volume 7, Article number: A69 (2007)
"Chemical analysis, risk assessment and elimination of selected cytostatic agents from hospital waste water", performed at the University Hospital (AKH) Vienna.
Drugs: 5-fluorouracil, doxorubicin, epirubicin, daunorubicin, cisplatin, carboplatin, oxaliplatin. Model calculation: Minimum, maximum annual average concentrations and cumulative amount in hospital sewage were calculated. Parameters: drug, water consumption in the oncologic in-patient treatment ward, renal human excretion rate. Chemical analysis: platinum compounds: ICP-MS (speciation analysis by on-line coupling of HPLC to ICP-MS), limits of detection: cisplatin (0.09 μg/l), carboplatin (0.1 μg/l), oxaliplatin (0.15 μg/l). Anthracyclines: solid phase extraction, HPLC and fluorescence detection (FLD), limits of detection: doxorubicin (0.05 μg/l), daunorubicin (0.06 μg/l). 5-Fluorouracil: solid phase extraction, capillary electrophoresis, limit of detection 1.7 μg/l. Chemical monitoring: waste water samples: effluent of (a) the total hospital (TH), (b) the oncological ward (OW), collected before dilution in the Vienna sewer system for a total period of 98 days.
Pt concentrations ranged from 3.2 to 266 μg/l; estimates revealed that about one third of the administered drugs was detected in the waste water of the oncologic ward. 5-Fluorouracil was detected in waste water up to 124 μg/l, doxorubicin up to 1.35 μg/l. The concentrations determined chemically agreed with the predictions based upon model calculations.
