Paíga, Paula; Correia, Manuela; Fernandes, Maria João; Silva, Ana Margarida; Martins de Carvalho, Maria Manuela; Vieira, Joana; Jorge, SandraThe removal efficiency of pharmaceuticals in wastewater treatment plants (WWTPs) is variable and some of these compounds pass these plants almost intact and others presenting a removal efficiency close to 100%. Their incomplete removal results in a continuous discharge of pharmaceuticals into the environment. To assess the profile of contamination of influents and effluents over a day, a set of 83 pharmaceutica...
Monitoring survey of caffeine in surface waters (Lis River) and wastewaters loc...
Paíga, Paula; Ramos, Sandra; Jorge, Sandra; Silva, Jaime Gabriel; Delerue-Matos, CristinaInvestigation during 11-month period was performed to study the presence of caffeine in the Lis River in Leiria Town in Portugal, and a monitoring during 9-month period was realized to check the contribution of the human pollution of two wastewater treatment plants (WWTPs) that discharge their effluents to the studied river. The samples were collected in five sampling points along the river and in two influents...

Paíga, Paula; Santos, Lúcia H.M.L.M.; Ramos, Sandra; Jorge, Sandra; Silva, Jaime Gabriel; Delerue-Matos, CristinaThe occurrence of 33 pharmaceuticals and metaboliteswas evaluated along the Lis river and in the influents and effluents of twowastewater treatment plants (WWTPs) located along the river. Results indicate that pharmaceuticals, such as ibuprofen, ketoprofen, carbamazepine and fluoxetine, and the metabolite salicylic acid are widespread along the Lis river, showing 100% of detection frequency, at levels up to 1.3...
