Characterization of a leachate from a sanitary intermunicipal landfill. Analysi...
Mestrinho, E; Ribeiro, V; Pinto, A P; Lopes, M EIn this work the content in seven metals was analysed in samples from a leachate, collected in a sanitary intermunicipal landfill. Samples were collected in three stages of the wastewater treatment plant, just before the biological treatment, just after the biological treatment and from the ultrafiltration permeate. Pb, Cr, Cu, Fe, Mn, Cd, Zn content was determined. Fe was the most abundant of the analysed meta...
Removal of Diclofenac by constructed wetlands planted with Phragmites australis...
Teixeira, D. Martins; Silva, Z.; Carvalho, A. J. Palace; Pinto, A. P.; Dordio, A.In the modern society, an ever increasing number of pharmaceutical active compounds (PhACs) is used for the treatment and prevention of various diseases. Ingested drugs are only partially absorbed by the organisms and studies have shown that the excreted compounds are only partially removed in the sewage treatment plants (STPs) [1]. Diclofenac is a non-steroidal anti-inflammatory drug taken to reduce inflammati...
Remoção e metabolização de Dexametasona por plantas da família das macrófitas
Silva, M.; Serrano, C.; Pires, T.; Carvalho, A. P.; Dordio, A. V.; Pinto, A. P.; Teixeira, D. M.A presença de compostos farmacêuticos e seus metabolitos no ambiente aquático tornou-se nos últimos anos um problema ambiental emergente. Assim, tornou-se essencial o desenvolvimento de processos de remoção mais eficientes, como o tratamento de efluentes com leitos construídos de macrófitas (LCM) que, em muitos casos, tem permitido a obtenção de águas residuais finais de boa qualidade. Este trabalho teve como o...
Resultados preliminares relativos à quantificação dos níveis endógenos de auxin...
Peixe, A.; Antunes, A.; Hegewald, H.; Costa, C.; Pinto, A.P.Analisaram-se para os dois cultivares em estudo os conteúdos endógenos de Ácido-indol-3-acético (AIA) e Ácido-indol-3-butírico (AIB) e avaliou-se a actividade das polifenoloxidases, peroxidases e AIA-oxidase em tecidos da região basal de estacas semi-lenhosas obtidas a partir da zona média de ramos do ano em fase de crescimento activo. As amostras foram recolhidas antes (Tempo 0) e após dopagem das estacas com ...
Improvement in soil and sorghum health following the application of polyacrylat...
Varennes, Amarilis de; Mourato, M.P.; Martins, L.L.; Cardoso, A.I.; Mota, A.M.; Pinto, A.P.; Gonçalves, M.L.; Guiwei, QuResearch Article ; Contamination of soils with cadmium (Cd) is a serious global issue due to its high mobility and toxicity. We investigated the application of insoluble polyacrylate polymers to improve soil and plant health. Sorghum was grown in a Cd-contaminated sandy soil. Polyacrylate polymers at 0.2% (w/w) were added to half of the soil. Control soil without plants was also included in the experiment. Gro...
Abandoned mine slags analysis by EPMA WDS x-ray mapping
Guimarães, Fernanda; Rosado, L.; Morais, C.; Candeias, A. E.; Pinto, A. P.; Mirão, J. P.The mining activity on the Iberian pyritic Belt (Portugal and Spain) started before Phoenician times, became particularly intense during the Roman occupation of the Iberian Peninsula (for gold) and after the industrial revolution (for gold, copper, zinc, lead and sulphur). The commonest ore of this region is a massive polymetalic sulphide accumulation, where pyrite (FeS2) is the main mineral, with variable conc...
Association of the heart fatty acid-binding protein gene with quality of carcas...
Figueiredo,F.C.; Lopes,P.S.; Pinto,A.P.G.; Paiva,D.A.F.; Mendonça,P.T.; Guimarães,S.E.F.The heart fatty acid-binding protein (HFABP) gene was sequenced in parental animals of a F2 crossing of boars of the Brazilian native Piau breed with commercial sows (Landrace x Large White Pietrain). Primers used for PCR were designed to amplify four exons of the gene. The PCR products were sequenced and compared with the GenBank sequences. Differences between the generated sequences and the GenBank sequences ...
Quantificação dos níveis endógenos de auxinas e da actividade enzimática das po...
Serra, C.; Antunes, R.; Hegewald, H.; Teixeira da Costa, C.; Pinto, A.P.; Peixe, A.A actividade enzimática de polifenoloxidases foi avaliada em folhas e na zona apical, média e basal de ramos de duas cultivares de oliveira (Olea europaea L.), comuns no Alentejo ( Galega vulgar e Cobrançosa ), mostrando que a actividade enzimática nas folhas foi muito superior à encontrada em tecidos de ramos do ano. Maior actividade enzimática foi também detectada na variedade Cobrançosa versus Galega vu...
Extracção sequencial em sedimentos e resíduos da antiga mina da Tinoca: geoquím...
Morais, C.; Mirão, J.; Rosado, L.; Pinto, A.P.; Lopes, M.E.; Nogueira, P.; Candeias, A.E.Mine wastes and sediments from the ancient copper mine of Tinoca (Alto Alentejo – Portugal) were submitted to a sequential extraction with the objective to establish distribution patterns for copper (Cu), iron (Fe), zinc (Zn) and lead (Pb) in different specific phases: amorphous oxides; rystalline oxides; sulphides and silicates. The results of the sequential extraction showed that Cu and Fe were pr...
