3D electrochemical cork granule process for the removal of pharmaceuticals from...
Remor, Paula V.; Soares, Cristina; Correia-Sá, Luísa; Paíga, Paula; Alves, Ana Rita; Pizzaia, Anita; Lapa, Nuno; Surra, Elena; Moreira, Francisca C.This study evaluates a three-dimensional (3D) electrochemical process employing cork granules as particle electrodes for removing contaminants of emerging concern (CECs) from urban wastewater. Tests in two reactors of different dimensions (Reactor A - 150 mL; Reactor B - 750 mL), with and without spiking of sulfamethoxazole (SMX) and trimethoprim (TMP), were performed and compared with the conventional 2D proce...
Sustainable carotenoid extraction from macroalgae: Optimizing microwave-assiste...
Lopes, Andreia; Correia-Sá, Luísa; Vieira, Mónica; Delerue-Matos, Cristina; Soares, Cristina; Grosso, Clara; Vieira, MónicaThis study aimed at optimizing carotenoid extraction using the macroalga Himanthalia elongata (L.) S.F.Gray as a model. Firstly, traditional extraction procedures were employed, using various solvents and temperatures to enhance the extraction conditions. Once the most effective extraction conditions were identified, the study transitioned to a more efficient and environmentally friendly approach, microwave-ass...
Trace elements in portuguese children: urinary levels and exposure predictors
Correia-Sá, Luísa; Fernandes, Virgínia C.; Maia, Maria Luz; Pinto, Edgar; Norberto, Sónia; Almeida, Agostinho; Santos, Cristina; Delerue-Matos, CristinaExposure to environmental chemicals during developmental stages can result in several adverse outcomes. In this study, the exposure of Portuguese children to Cu, Co, I, Mo, Mn, Ni, As, Sb, Cd, Pb, Sn and Tl was evaluated through the analysis of first morning urine through ICP-MS. Furthermore, we attempted to determine possible exposure predictors. The study sample consisted of 54% girls and 46% boys, with a med...
Removal of diclofenac and sulfamethoxazole from aqueous solutions and wastewate...
Soares, Cristina; Correia-Sá, Luísa; Paíga, Paula; Barbosa, Carlos; Remor, Paula Verônica; Freitas, Olga; Moreira, Manuela M.; Nouws, HenriThe three-dimensional (3D) electrochemical treatment process was studied for the removal of two pharmaceuticals, diclofenac (anti-inflammatory) and sulfamethoxazole (antibiotic), in mono and bi-component systems. Adsorption and conventional two-dimensional electrochemical processes were initially studied and then combined to develop the 3D process. The influence of different operating parameters on the removal ...
Micro-QuEChERS extraction coupled to GC–MS for a fast determination of Bispheno...
Correia-Sá, Luísa; Norberto, Sónia; Delerue-Matos, Cristina; Calhau, Conceição; Domingues, Valentina F.Bisphenol A (BPA) is considered an endocrine disruptor and public concern over BPA exposure has been raised. Several studies have assessed human exposure to this plasticizer, confirming its ubiquitous presence and highlighting children as a public of special concern. A simple, efficient, cheap and green analytical procedure is reported within this paper. This paper reports, for the first time, the development o...
Phthalates and type 1 diabetes: is there any link?
Castro-Correia, Cíntia; Correia-Sá, Luísa; Norberto, Sónia; Delerue-Matos, Cristina; Domingues, Valentina; Costa-Santos, Cristina; Fontoura, ManuelPhthalates are a group of chemical compounds used as plasticizers in the manufacture of plastic materials. They can be present in many commonly used products. There seems to be a relationship between exposure to phthalates and the occurrence of metabolic dysfunctions, such as a decrease in glucose tolerance, oxidative stress, loss of beta cells, and a decrease in insulin synthesis. As beta cells play a key role...
Obesity or diet? Levels and determinants of phthalate body burden – A case stud...
Correia-Sá, Luísa; Kasper-Sonnenberg, Monika; Pälmke, Claudia; Schütze, André; Norberto, Sónia; Calhau, Conceição; Domingues, Valentina F.In this study we analyzed one of the most comprehensive sets of 21 urinary phthalate metabolites representing exposure to 11 parent phthalates (DEP, DMP, DiBP, DnBP, BBzP, DEHP, DiNP, DiDP, DCHP, DnPeP, DnOP) in first morning urine samples of 112 Portuguese children (4-18 years) sampled in 2014/15. The study population consisted of two groups: group 1 with normal weight/underweight children (N = 43) following t...
Application of the QuEChERS method for the determination of organochlorine pest...
Paz, Mário; Correia-Sá, Luísa; Vidal, Carla B.; Becker, Helena; Longhinotti, Elisane; Domingues, Valentina F.; Delerue-Matos, CristinaThe Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method was applied to the extraction of 14 organochlorine pesticides (OCPs) residues from commercial fruit pulps available in supermarkets in Fortaleza, Northeastern Brazil. The analyses were carried out by gas chromatography (GC), coupled to an electron-capture detector (ECD), and were confirmed by GC-tandem mass spectrometry (MS). The parameters o...
Exposure assessment to bisphenol A (BPA) in Portuguese children by human biomon...
Correia-Sá, Luísa; Kasper-Sonnenberg, Monika; Schütze, André; Pälmke, Claudia; Norberto, Sónia; Calhau, Conceição; Domingues, Valentina; Koch, Holger M.Exposure to bisphenol A (BPA) is known to be widespread and available data suggests that BPA can act as an endocrine disruptor. Diet is generally regarded as the dominant BPA exposure source, namely through leaching to food from packaging materials. The aim of this study was to evaluate the exposure of 110 Portuguese children (4-18 years old), divided in two groups: the regular diet group (n = 43) comprised hea...
Exposure of Portuguese children to the novel non-phthalate plasticizer di-(iso-...
Correia-Sá, Luísa; Schütze, André; Norberto, Sónia; Calhau, Conceição; Domingues, Valentina; Koch, Holger M.Di-(iso-nonyl)-cyclohexane-1,2-dicarboxylate (DINCH) is used as substitute for high molecular weight phthalate plasticizers such as di-(2-ethylhexyl) phthalate (DEHP) and di-(iso-nonyl) phthalate (DINP). Due to a rapid substitution process we have to assume omnipresent and increasing DINCH exposures. The aim of this study was to evaluate DINCH exposure in 112 children (4-18years old) from Portugal, divided in t...
