BY SPE-UPLC-ESI-MS/MS.A method was developed for the analysis of 31 pharmaceutical compounds in Lisbon's drinking water system, using solid-phase extraction (SPE) and ultraperformance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS).The validated through estimation linearity range, detection quantification limits, matrix effects, precision accuracy.The limit ranges were 0.009-10 0.03-33 ng/L, respectively.Analytes quantified samples collected from EPAL (Empresa...
This study evaluates the efficiency of nanofiltration to remove pesticides and polycyclic aromatic hydrocarbons (PAHs) from drinking water sources with different compositions (groundwater, spring water, surface after sedimentation) as well main mechanisms governing rejection these compounds. All compounds were highly removed matrices due strong hydrophobic interactions between membrane. Lower variable rejections obtained for in natural matrices. Atrazine was found be independent matrix...
The aim of this study was developed and validated an analytical method based on liquid chromatography tandem mass spectrometry after solid phase extraction to monitorizing ten endocrine hormone disrupters in Lisbon drinking water system. Natural synthetic hormones (17-β-estradiol, ethinylestradiol, estriol, estrone, progesterone, mestranol diethylstilbestrol) some industrial products (4-n-nonylphenol, 4-tert-octylphenol bisphenol A) were studied. Mass spectrometer detection parameters...
The objective of this study was to identify the scientific production on theInternational Classification Functioning, Disability and Health (ICF) andconsi...
Contamination of surface and groundwater sources with pesticide residues has been great concern for a long time it is major challenge the preservation sustainability environment. In order to accomplish requirements European Directive 98/83/EC, we developed validated an analytical method based on combination gas chromatography tandem quadrupole mass spectrometry (GC-MS/MS) using solid-phase extraction as sample preparation. this work nine pesticides were studied: molinate, simazine, atrazine,...
Objetivou-se conhecer e avaliar o perfil de adolescentes do ensino médio sobre a doação sangue. Trata-se um estudo transversal, com abordagem quantitativa, realizado em uma instituição educação pública localizada município no interior Mato Grosso, na Amazônia Brasileira. Participaram da pesquisa 114 idade entre 15 19 anos. A coleta aconteceu 2023 por meio questionário. análise estatística foi feita programa EpiInfo. maioria dos era sexo feminino (57,9%); prevalência 17 anos; sendo que...
Concerns arise from the possible occurrence of pathogens in drinking water pipe biofilms and storage tank sediments. In these studies, biofilm samples pipes sediments tanks Lisbon distribution system were analyzed. Protein determinations heterotrophic counts on used to assess network sessile colonization intensity distribution. Indicator pathogenic microorganisms analyzed samples, as well sediments, by using cultural methods PCR, risks. Results have shown that is relatively weak intensity....
Loose deposits (LD) accumulate in drinking water distribution systems (DWDS) and may lead to tap discoloration incidents upon resuspension. While inconvenient for the consumers companies, be accompanied by degradation of microbiological quality water, possibly transport bacteria. The presence heterotrophic bacteria towards LD with different characteristics was investigated. Bacterial loads discoloured samples concentrated over settling times were analysed. Total (TH) numbers did not relate...
