Environmental monitoring, particularly of water, is crucial to screen and preselect potential hazardous substances for policy guidance risk minimisation strategies. In Portugal, extensive data are missing. This work aimed perform a qualitative survey antibiotics in surface- groundwater, reflecting demographic, spatial, consumption drug profiles during an observational period three years. A passive sampling technique (POCIS) high-resolution chromatographic system were used monitor analyse the...
Forty polybrominated diphenyl ethers (PBDEs), from mono- through hepta-brominated, were analyzed in river and coastal sediment samples of the eight main basins Portugal to investigate occurrence, geographical distribution, detailed congener profiles. Thirty-two taken along different rivers inland open sea revealed an increase toward mouth with a total PBDE concentration 20 ng/g-dw, levels decreased 0.5 ng/g-dw sediments. PBDEs detected all analyzed, indicating diffuse source pollution...
Objetivo: Compreender o papel da inteligência artificial (IA) na detecção, diagnóstico, monitoramento e prognóstico insuficiência cardíaca (IC). Métodos: Trata-se de uma revisão bibliográfica integrativa, qual foi utilizada a base dados PubMed Central (PMC). Inicialmente, foram identificados 945 artigos, que submetidos critérios elegibilidade. Dentre esses, 15 artigos selecionados para elaboração deste estudo. Resultados: A IC é das principais condições crônicas caráter cardiovascular, cuja...
Objetivo: Analisar a aplicabilidade da Inteligência Artificial (IA) na anestesiologia, destacando seus benefícios e desafios prática médica. Métodos: Revisão integrativa realizada base de dados PubMed Central (PMC), utilizando os termos "artificial intelligence" "anesthesiology", abrangendo o período 2019 2024. Foram identificados 1.150 artigos, dos quais 15 foram selecionados para análise detalhada. Resultados: A IA demonstrou várias aplicações importantes como aprimoramento das técnicas...
The occurrence of the endocrine disruptor compounds, such as 4-nonylphenol isomers and bisphenol A was determined in surface water samples from Portugal. analytical method used involved preconcentration 200 mL sample by solid phase extraction (SPE) using a OASIS (Waters) cartridge, followed Gas Chromatography-Mass Spectrometry (GC/MS) determination. Recoveries limits detection bisphenol-A were 73 % 119 %, respectively, 0.01 mug L-1 0.002 L-1. applied to determination these estrogenic...
Water samples (n = 183) from Portuguese rivers were tested for the presence of endocrine disruptors using recombinant yeast assay (RYA) combined with chemical identification compounds having endocrine-disruption properties by liquid chromatography coupled to mass spectrometry. Ten selected locations sampled monthly a period 20 months, April 2001 December 2002. More than 90% showed either no detectable or low levels estrogenicity (<0.1 ng/L estradiol equivalents). The remaining (17 in total,...
The environmental release of antimicrobial pharmaceuticals is an imminent threat due to ecological impacts and microbial resistance phenomena. recent COVID-19 outbreak will likely lead greater loads antimicrobials in the environment. Thus, identifying most used pose risks would be valuable. For that, ambulatory hospital consumption patterns Portugal during pandemic (2020-2021) were compared with those 2019. A predicted risk assessment screening approach based on exposure hazard surface water...
ABSTRACT The objective of this study was to evaluate the growth and accumulation ions in lettuce grown different hydroponic systems recirculation frequencies. experimental design randomized blocks with 8 treatments 4 replicates. evaluated were Nutrient Flow Technique (NFT) an adapted Deep (DFT), latter frequencies 0.25, 2 h. Both used fresh water brackish water. Plant growth, inorganic solutes (Na+, K+, Cl- NO3-) correlation between dry matter production Na+/K+ Cl-/NO3- evaluated. salinity...
The aim of this study was the groundwater evaluation to pesticide compounds and nitrates in oriziculture areas 'Baixo Sado' region (Portugal), based on their use, predictive approaches, field laboratory work. One or more analysed (chlorfenvinphos, cycloxydim, 3,4-dichloroaniline, endosulphan, MCPA, molinate, oxadiazon, profoxydim, propanil) were detected 62% 171 water samples collected from 22 wells used for public supply, domestic irrigation, during 2002 2003. From total samples, 6%...
Abstract Various chemometric data analysis methods, such as principal components analysis, multivariate curve resolution—alternating least squares, parallel factor and Tucker3, are proposed compared for the resolution modeling of main contamination sources in a large environmental array obtained an exhaustive monitoring program that examined quality surface waters Portugal. The study covered 19 priority semivolatile organic compounds (SVOCs) frequently found total number 644 water samples,...
Antifungals support modern medical and agricultural practices, extensive screening environmental data are missing. This work aims to survey antifungals for purposes in surface- groundwater Portugal. A passive sampling technique a high-resolution chromatographic system were used. applied practice not detected as only (fungicides). Thirty-nine different fungicide molecules found; its detection frequency was dominated by rabenzazole (61%, 92%) ethoxyquin (54%, 77%); among the five fungicides...
