Abstract. The Amazon Basin plays key role in atmospheric chemistry, biodiversity and climate change. In this study we applied nanoelectrospray (nanoESI) ultra-high-resolution mass spectrometry (UHRMS) for the analysis of organic fraction PM2.5 aerosol samples collected during dry wet seasons at a site central Amazonia receiving background air masses, biomass burning urban pollution. Comprehensive spectral data evaluation methods (e.g. Kendrick defect, Van Krevelen diagrams, carbon oxidation...
To better understand the conditions which have led to one of largest COVID-19 outbreaks in Belgian nursing homes 2020.A home Flanders, Belgium, experienced a massive outbreak after cultural event. An external volunteer who dressed as legendary figure visited consecutively 4 living units on December, 4th and tested positive for SARS-CoV-2 next day. Within days, residents started display symptoms spread rapidly within home.We interviewed key informants collected standardized data from all...
As worldwide evidence shows that the predominant transmission route of SARS-CoV-2 and other respiratory pathogens is airborne, need for suitable methods sampling bioparticles directly from air more urgent than ever. The present paper describes development a method collection biological aerosols, using preexisting cyclonic impinger, Coriolis μ, combined with lysis buffer subsequent qPCR analysis generated samples in lab. Four phases are described: exploratory, validation, blank tests,...
Ventilation is critical in interpreting indoor air quality (IAQ), yet most IAQ assessments do not report ventilation adequately. Most use tracer gas tests (TGT) to measure total change rate (ACH), but currently applied TGTs present three shortcomings: limited comparability between ACH and data, inadequate substances employed as gases tendency bias arising from perfect-mixing assumption. This paper proposes a new TGT approach, employing an alternative that captured/analysed using commercial...
This paper describes the development of a new adaptation traditional tracer gas test (TGT) used for total air change rates (ACH) measurement. adapted TGT, based on constant injection, is intended use in large-scale IAQ assessments and employs an alternative that more adequate than currently employed SF6 perfluorocarbons, can be co-captured co-analyzed with commonly assessed VOCs by commercial passive IAQ-sampling. As it sampling, proposed TGT yields long-term integrated ACH values, thus...
