“…Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most frequently detected pharmaceuticals in environmental samples and among the most widespread drugs in the world [5,6]. Diclofenac (2-(2,6-dichloranilino) phenylacetic acid, hereinafter DCF, chemical formula C 14 H 11 Cl 2 NO 2 ), belongs to this family of medicines.…”

“…The behaviour of ketoprofen might be justified by its difficult removal during wastewater treatment, being consistently found in surface waters (Shanmugam et al, 2014). Ketoprofen can also occur as ion at neutral or basic pH, and therefore is not readily adsorbed on particulate material, remaining in the aqueous phase (Araujo et al, 2014). On the other hand, the higher levels of pharmaceu-ticals observed in August and early September can be explained by an increase in population in the study area during these months, due to a higher level of tourists at that time, either by summer holidays or by an increment in the traffic of cruise boats in Leixões harbour (INE, 2014).…”

A B S T R A C TThe occurrence of seven pharmaceuticals and two metabolites belonging to non-steroidal anti-inflammatory drugs and analgesics therapeutic classes was studied in seawaters. A total of 101 samples covering fourteen beaches and five cities were evaluated in order to assess the spatial distribution of pharmaceuticals among north Portuguese coast. Seawaters were selected in order to embrace different bathing water quality (excellent, good and sufficient). Acetaminophen, ketoprofen and the metabolite hydroxyibuprofen were detected in all the seawater samples at maximum concentrations of 584, 89.7 and 287 ng L −1 , respectively. Carboxyibuprofen had the highest seawater concentration (1227 ng L −1 ). The temporal distribution of the selected pharmaceuticals during the bathing season showed that, in general, higher concentrations were detected in August and Septem-ber. The environmental risk posed by the pharmaceuticals detected in seawaters towards different trophic levels (fish, daphnids and algae) was also assessed. Only diclofenac showed hazard quotients above one for fish, representing a potential risk for aquatic organisms. These results were observed in seawaters classified as excellent bathing water. Additional data is needed in order to support the identification and prioritization of risks posed by pharmaceuticals in marine environment.

“…As a matter of fact, the presence of trace pharmaceuticals and other xenobiotic compounds in drinking and superficial waters is a major public health concern, since little is known about the potential chronic effect on human health of the long-term ingestion of mixtures of these substances. Thus, over the past few years, both the occurrence and fate of pharmaceutical residues have attracted the interest of the scientific community (Georgaki et al 2014;Araujo et al 2014). …”

The presence of trace of pharmaceutical compounds (PhACs) in groundwater and in drinking and superficial waters is a major public health concern. Recently, various advanced treatment technologies have been studied to remove these kinds of pollutants; among them, combined treatments based on UV light appear to be more eco-friendly and with very interesting removal efficiencies if properly modified. In this paper, the removal of Ibuprofen (IBP) from synthetic water streams was investigated by using a lab-scale experimental device consisting of a batch reactor equipped with a lamp emitting monochromatic UV light (254 nm; 400 mJ m −2 ). The IBP initial concentration (C IBP 0 ) was 45.9 mg L −1 . Two sets of experiments were carried out; the first one was aimed at studying the IBP concentration as a function of time, at different volumes of treated solution; the second one was aimed at exploring the effect of pH on IBP degradation as a function of time.The results obtained show that the concentration of IBP decreases along with treatment time, with a negative effect of the treated volume, i.e., smaller volumes, that is lower liquid heights, are more easily degraded. Moreover, the higher the pH, the better the IBP degradation; actually when pH increases from 2.25 to 5.51 and finally to 8.25, the IBP concentration, after an hour of treatment, decreases respectively to 45, 34, and 27 % from its initial value. A reaction mechanism is suggested, which well describes the effects of volume and pH on the experimentally measured IBP degradation.
