PM2.5 chemical composition and health risks by inhalation near a chemical complex

Particulate matter (PM2.5) samples were collected in the vicinity of an industrial chemical pole and analysed for organic and elemental carbon (OC and EC), 47 trace elements and around 150 organic constituents. On average, OC and EC accounted for 25.2% and 11.4% of the PM2.5 mass, respectively. Organic compounds comprised polycyclic aromatic hydrocarbons (PAHs), alkylated PAHs, anhydrosugars, phenolics, aromati...

Nighttime-daytime PM10 source apportionment and toxicity in a remoteness inland...

The distribution of daytime and nighttime sources of PM10 collected from January to March 2021 at an urban background site in the city of Braganca, Portugal, was performed using positive matrix factorisation (PMF). Additional data of PM2.5, NOx and meteorological variables were collected to support the interpretations. A solution with 5 factor profiles was found: traffic (33%), dust (24%), biomass burning (21%)...

Black Carbon source apportionment from fossil fuel and biomass burning in a sub...

Source apportionment of PM2.5 before and after COVID-19 lockdown in an urban-in...

The lockdowns held due to the COVID-19 pandemic conducted to changes in air quality. This study aimed to understand the variability of PM2.5 levels and composition in an urban-industrial area of the Lisbon Metropolitan Area and to identify the contribution of the different sources. The composition of PM2.5 was assessed for 24 elements (by PIXE), secondary inorganic ions and black carbon. The PM2.5 mean concentr...

Monitorização Quadrienal de Nitratos nos Recursos Hídricos Subterrâneos da Zona...

O Conselho das Comunidades Europeias em 1991, através da Diretiva 91/676/CEE de 12 de dezembro de 1991, reconheceu a importância de proteger as áreas de elevada suscetibilidade para a poluição das águas, causada ou induzida por nitratos (NO3-) de origem agrícola. Uma dessas áreas é a Zona Vulnerável a Nitratos (ZVN) de Esposende -Vila do Conde, criada em 1997 pela Portaria n.º 1037/1997 de 1 de outubro, à data ...

COVID-19: adaptation of a primary health care facility to the new accessibility...

The COVID-19 pandemic forced a quick adaptation of the health services so that the response and quality of care could be maintained. In order to guarantee the accessibility of users to primary health care and minimize the consequences of social distancing, offering alternatives to face-to-face consultation, our family health unit created a support line for the patients. The health professionals of this primary ...

Intervenções não farmacológicas implementadas por enfermeiros no controlo da do...

Objetivo: Identificar e mapear a evidência científica existente no âmbito das intervenções não farmacológicas implementadas por enfermeiros, com o objetivo de proporcionar controlo da dor, da pessoa em situação paliativa. Metodologia: Protocolo de Scoping review com base na metodologia proposta pelo Joanna Briggs Institute. Na pesquisa e identificação dos estudos, serão usadas as bases de dados eletrónicas MEDL...
