Publikation Soziale Ungleichheit und Covid-19. Schwere Covid-19-Verläufe mit Spitalaufenthalt und der Einfluss von Demografie, Vorerkrankung, Sozialstatus und Expositionsrisiken(Schweizerisches Gesundheitsobervatorium OBSAN, 2024) Bayer-Oglesby, Lucy; Bachmann, Nicole; Sepahniya, Samin; Jörg, RetoDas Bulletin untersucht soziale Ungleichheiten in der Covid-19-Pandemie. Auf Basis einer Datenverknüpfung zwischen der Strukturerhebung (SE) und der Medizinischen Statistik (MS) wird untersucht, welche Teile der Schweizer Bevölkerung in den Pandemiejahren 2020 und 2021 ein erhöhtes Risiko für einen Spitalaufenthalt wegen Covid-19 aufwiesen und welche Rolle dabei die soziale Lage, die Wohnsituation und der Beruf spielten. Ausserdem thematisiert das Bulletin die Rolle schwerer Vorerkrankungen und zeigt auf, wie sich die sozialen Ungleichheiten bei schweren Covid-19-Verläufen mit der Zugänglichkeit von Impfungen verändert haben.01B - Beitrag in Magazin oder ZeitungPublikation Soziale Ungleichheit und schwere COVID-19 – Verläufe in der Schweizer Migrationsbevölkerung 2020-2021(07.12.2023) Bayer-Oglesby, Lucy; Bachmann, Nicole06 - PräsentationPublikation Population sampling in European air pollution exposure study, EXPOLIS: comparisons between the cities and representativeness of the samples(Nature, 2000) Rotko, Tuulia; Bayer-Oglesby, Lucy; Künzli, Nino; Jantunen, Matti J.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Soziale Ungleichheit und schwere COVID-19 – Verläufe in der Schweizer Bevölkerung 2020-2021(04.06.2024) Bachmann, Nicole; Bayer-Oglesby, Lucy06 - PräsentationPublikation Soziale Ungleichheit und schwere Covid-19-Verläufe in der Migrationsbevölkerung.

Additionally, PM10 measurements from the following year, which were concurrently recorded at two urban and two rural sites, were compared. Generally, the spatial variability of PM4, PM10, and total suspended particulates (TSP) within this Swiss urban environment (area = 36 km2) was rather limited. With the exception of one site in a street canyon next to a traffic light, traffic density had only a weak tendency to increase the levels of PM. Mean PM10 concentration at six sites with different traffic densities was in the range of less than ±10% of the mean urban PM10 level. However, comparing the mean PM levels on workdays to that on weekends indicated that the impact of human activities, including traffic, on ambient PM levels may be considerable. Differences in the daily PM10 concentrations between urban and more elevated rural sites were strongly influenced by the stability of the atmosphere. In summer, when no persistent surface inversions exist, differences between urban and rural sites were rather small. It can therefore be concluded that spatial variability of annual mean PM concentration between urban and rural sites in the Basel area may more likely be caused by varying altitude than by distance to the city center.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Temporal and spatial variation of the chemical composition of PM10 at urban and rural sites in the Basel area, Switzerland(Elsevier, 2001) Röösli, M; Theis, G; Künzli, N; Staehelin, J; Mathys, P; Bayer-Oglesby, Lucy; Camenzind, M; Braun-Fahrländer, ChParticulate matter measurements of di!erent size fractions (PM , PM , TSP) were performed in the Basel area (Switzerland) at seven urban sites throughout 1997 and at two urban and two rural sites during the following year (April 1998 May 1999). Based on a sample of "lters which was chemically analyzed, we investigated the chemical composition of PM both within the city of Basel and among urban and rural sites. The temporal and spatial variability of the chemical composition of PM was evaluated taking into account additional data frommeteorology and further air pollutants. The chemical analyses of PM showed that carbonaceous substances (elemental carbon, organic matter) and inorganic substances of secondary origin such as sulfate, nitrate and ammonium were the most abundant component of PM in the Basel area (approximately 60}70%). Di!erence in the PM concentration between urban and rural sites was larger during the cold season than during the warmseason. This was mainly due to the presence of an inversion layer between the city and the more elevated rural sites resulting in higher concentrations of nitrate, ammonium and organic matter in the city during the cold season. The higher PM concentration on workdays compared to weekends was mostly a result of the temporal variation of the concentration of Ca, elemental carbon, Ti, Mn, and Fe, indicating that these compounds are for the most part caused by regional human activities. Although total PM mass concentration was found to be in general uniformly distributed within the city of Basel, the chemical composition was more variable due to specific sources like road trafic and other anthropogenic emissions.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Comparison of Black Smoke and PM2.5 Levels in Indoor and Outdoor Environments of Four European Cities(American Chemical Society, 2002) Götschi, Thomas; Bayer-Oglesby, Lucy; Mathys, Patrick; Monn, Christian; Manalis, Nikos; Koistinen, Kimmo; Jantunen, Matti; Hänninen, Otto; Polanska, Liba; Künzli, NinoRecent studies on separated particle-size fractions highlight the health significance of particulate matter smaller than 2.5 μm (PM2.5), but gravimetric methods do not identify specific particle sources. Diesel exhaust particles (DEP) contain elemental carbon (EC), the dominant light-absorbing substance in the atmosphere. Black smoke (BS) is a measure for light absorption of PM and, thus, an alternative way to estimating EC concentrations, which may serve as a proxy for diesel exhaust emissions. We analyzed PM2.5 and BS data collected within the EXPOLIS study (Air Pollution Exposure Distribution within Adult Urban Populations in Europe) in Athens, Basel, Helsinki, and Prague. 186 indoor/outdoor filter pairs were sampled and analyzed. PM2.5 and BS levels were lowest in Helsinki, moderate in Basel, and remarkably higher in Athens and Prague. In each city, Spearman correlation coefficients of indoor versus outdoor were higher for BS (range rSpearman: 0.57−0.86) than for PM2.5 (0.05−0.69). In a BS linear regression model (all data), outdoor levels explained clearly more of indoor variation (86%) than in the corresponding PM2.5 model (59%). In conclusion, ambient BS seizes a health-relevant fraction of fine particles to which people are exposed indoors and outdoors and exposure to which can be assessed by monitoring outdoor concentrations. BS measured on PM2.5 filters can be recommended as a valid and cheap additional indicator in studies on combustion-related air pollution and health.01A - Beitrag in wissenschaftlicher Zeitschrift
