Abstract (EN): Minocycline, oxytetracycline, tetracycline, enrofloxacin and ceftiofur, commonly used veterinary pharmaceuticals, were searched in four urban, two livestock and two slaughterhouse effluents from wastewater treatment plants (WWTPs) in the north of Portugal. A simple method that includes solid-phase extraction followed with analysis by high-performance liquid chromatography with diode array detector was established and applied to the simultaneous determination of the five pharmaceuticals in WWTP effluents. This method, which is expeditious, inexpensive and available in most laboratories, showed to be useful for screening for problematic levels of drugs in WWTP effluents. It is known that several livestock and slaughterhouse effluents (pre-treated or treated) are discharged to the urban network before discharge into the environment. The presence of these drugs in such effluents can constitute a significant environmental problem that should be addressed, by the monitoring of these drugs and by implementation of methodologies that contribute to their decrease/elimination from wastewaters. Minocycline (<= 6 mu g L-1), oxytetracycline (<= 7 mu g L-1), tetracycline (<= 6 mu g L-1) and enrofloxacin (<2 mu g L-1) could be detected and/or quantified in three urban effluents. Detectable levels of enrofloxacin (<2 mu g L-1) and quantifiable levels of tetracycline (<= 15 mu g L-1) were found in the slaughterhouse effluents.
