Indoor air quality in a home improvement store: gaseous pollutants, bioburden a...

Ensuring good air quality is essential for safeguarding human health, requiring monitoring to comprehend air composition and formulate effective interventions. This study focused on indoor and outdoor air quality monitoring within a home improvement and gardening franchise store in northeastern Portugal. Real-time optical monitors recorded levels of particulate matter below 10 µm (PM10), while PM10 gravimetric ...

Fingerprinting and emission rates of particulate organic compounds from typical...

The aim of this study was a detailed chemical characterisation of the particles released during the preparation of popular Portuguese dishes. PM2.5 samples were collected from the exhaust stacks on the roofs of a university canteen, a charcoal-grilled chicken restaurant and a wood-oven roasted piglet restaurant. The speciation of organic compounds was carried out by gas chromatography-mass spectrometry. The can...

One-year study of airborne sugar compounds: cross-interpretation with other che...

The daily evolution of seventeen sugar compounds (seven saccharides, seven alcohol-saccharides and three anhydrosaccharides) in atmospheric aerosol samples collected between 9 March 2016 and 14 March 2017 was studied in León (Spain). The main links between the concentration of sugar compounds and various chemical species, pollen, fungal spores and meteorological conditions were investigated. The results showed ...

Intelligent process automation: An overview over the future of auditing

Financial auditing focuses on obtaining and assessing evidence, based on certain assertions. It is based on the scrutiny of companies' data, with the objective of obtaining appropriate and sufficient evidence that provides a reasonable degree of certainty that the financial statements are free from fraud and / or material errors, subsequently communicating the results to the stakeholders. However, the growing d...

Source apportionment of PM2.5 and PM10 by Ionic and Mass Balance (IMB) in a tra...

The recently developed Ion and Mass Balance (IMB) source apportionment methodology was applied to a traffic influenced urban aerosol, permitting the quantification of the contributions of 11 source components, or formation processes, which accounted for more than 96% of the measured aerosol mass loading. Main sources included exhaust and non-exhaust road vehicle emissions, biomass burning, secondary inorganic a...

Aethalometer measurements in a road tunnel: a step forward in the characterizat...

A sampling campaign was conducted in the Liberdade Avenue tunnel (Braga, Portugal) during a week (with 56,000 vehicles) to monitor black carbon (eBC-equivalent black carbon) by means of an Aethalometer AE-31, and gaseous pollutants (CO2, CO, NOx). Inside the tunnel, the mean eBC mass concentration was 21 ± 10 μg m-3, reaching a maximum hourly value of 49.0 μg m-3. An hourly and weekday-weekend study was carried...
