- PublikationDecline of Ambient Air Pollution Levels and Improved Respiratory Health in Swiss Children(National Institute of Environmental Health Sciences, 11/2005) Bayer-Oglesby, Lucy; Grize, Leticia; Gassner, Markus; Takken-Sahli, Kathy; Sennhauser, Felix H.; Neu, Urs; Schindler, Christian; Braun-Fahrländer, Charlotte [in: Environmental Health Perspectives]The causality of observed associations between air pollution and respiratory health in children is still subject to debate. If reduced air pollution exposure resulted in improved respiratory health of children, this would argue in favor of a causal relation. We investigated whether a rather moderate decline of air pollution levels in the 1990s in Switzerland was associated with a reduction in respiratory symptoms and diseases in school children. In nine Swiss communities, 9,591 children participated in cross-sectional health assessments between 1992 and 2001. Their parents completed identical questionnaires on health status and covariates. We assigned to each child an estimate of regional particles with an aerodynamic diameter < 10 μg/m3 (PM10) and determined change in PM10 since the first survey. Adjusted for socioeconomic, health-related, and indoor factors, declining PM10 was associated in logistic regression models with declining prevalence of chronic cough [odds ratio (OR) per 10-μg/m3 decline = 0.65, 95% confidence interval (CI), 0.54–0.79], bronchitis (OR = 0.66; 95% CI, 0.55–0.80), common cold (OR = 0.78; 95% CI, 0.68–0.89), nocturnal dry cough (OR = 0.70; 95% CI, 0.60–0.83), and conjunctivitis symptoms (OR = 0.81; 95% CI, 0.70–0.95). Changes in prevalence of sneezing during pollen season, asthma, and hay fever were not associated with the PM10 reduction. Our findings show that the reduction of air pollution exposures contributes to improved respiratory health in children. No threshold of adverse effects of PM10 was apparent because we observed the beneficial effects for relatively small changes of rather moderate air pollution levels. Current air pollution levels in Switzerland still exceed limit values of the Swiss Clean Air Act; thus, children’s health can be improved further.01A - Beitrag in wissenschaftlicher Zeitschrift

- PublikationLiving near main streets and respiratory symptoms in adults. the Swiss Cohort Study on Air Pollution and Lung Diseases in Adults(Oxford University Press, 10.10.2006) Bayer-Oglesby, Lucy; Schindler, Christian; Hazenkamp-von Arx, Marianne E.; Braun-Fahrländer, Charlotte; Keidel, Dirk; Rapp, Regula; Künzli, Nino; Braendli, Otto; Burdet, Luc; Sally Liu, L-J; Leuenberger, Philippe; Ackermann-Liebrich, Ursula [in: American Journal of Epidemiology]The Swiss Cohort Study on Air Pollution and Lung Diseases in Adults (SAPALDIA), conducted in 1991 (SAPALDIA 1) in eight areas among 9,651 randomly selected adults aged 18-60 years, reported associations among the prevalence of respiratory symptoms, nitrogen dioxide, and particles with an aerodynamic diameter of less than 10 microg/m3. Later, 8,047 subjects reenrolled in 2002 (SAPALDIA 2). The effects of individually assigned traffic exposures on reported respiratory symptoms were estimated, while controlling for socioeconomic and exposure- and health-related factors. The risk of attacks of breathlessness increased for all subjects by 13% (95% confidence interval: 3, 24) per 500-m increment in the length of main street segments within 200 m of the home and decreased in never smokers by 12% (95% confidence interval: 0, 22) per 100-m increment in distance from home to a main street. Living within 20 m of a main street increased the risks of regular phlegm by 15% (95% confidence interval: 0, 31) and wheezing with breathing problems by 34% (95% confidence interval: 0, 79) in never smokers. In 2002, the effects related to road distance were different from those in 1991, which could be due to changes in the traffic pollution mixture. These findings among a general population provide strong confirmation that living near busy streets leads to adverse respiratory health effects.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationPersonal exposure assessment studies may suffer from exposure-relevant selection bias(Nature, 27.07.2000) Bayer-Oglesby, Lucy; Rotko, Tuulia; Krütli, Pius; Boudet, Céline; Kruize, Hanneke; Jantunen, Matti; Künzli, Nino [in: Journal of Exposure Science & Environmental Epidemiology]We evaluated exposure-relevant selection bias within the framework of a study on personal air pollution exposure, using traffic data as exposure proxy. Based on random samples of 3000 (Basel) and 2532 (Helsinki) persons, 50 and 250 subjects, respectively, were recruited for direct monitoring and 250 (Basel, Helsinki) for indirect monitoring. In Basel, participants of direct monitoring as compared to non-participants were more likely to live at streets with low traffic volume (49% below 1st quartile vs. 27%). Adjusted for sex, age and nationality, an increase of 100 cars per hour was associated with 14% less participation (odds ratio (OR): 0.861; 95% CI: 0.731, 1.007). Although in Helsinki, traffic volume was neither significantly related to participation in direct nor indirect monitoring, the point estimates indicate a tendency to decreased participation with increasing traffic intensity at home. We conclude that selection bias regarding exposure-relevant characteristics is likely to occur when recruiting participants for studies including demanding personal exposure assessment. Correction for factors routinely collected may not fully account for exposure-relevant bias. This is of particular importance when using exposure data for modelling population exposure distributions, whereas in epidemiological studies, a reduced range of exposure must not a priori distort the exposure-response relationship.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationUrban gardening and green space governance: towards new collaborative planning practices(Cogitatio Press, 2016) Nikolaidou, Sofia; Klöti, Tanja; Tappert, Simone; Drilling, Matthias [in: Urban Planning]In the context of urban densification and central urban areas’ lack of open spaces, new forms of small-scale urban gardening practices have emerged. These gardening practices respond to urban pressures and open new modes of green space governance, presenting alternative and multifunctional ways to manage and revitalise cities. Focusing on the case of Geneva, the article unfolds two levels of discussion. On the one hand—and with reference to the theorist Habermas—it examines how multiple actors with different interests interplay and cooperate with each other in order to negotiate over open space, while discussing implications for local politics and planning. On the other hand, it describes how these negotiations result in new, innovative, and hybrid forms of public green space. The main findings indicate emerging forms of collaboration, partnerships, and governance patterns that involve public and private sectors and increase participation by civil society actors. Cooperation amongst several interested groups and the collective re-invention of public urban spaces increase these spaces’ accessibility for multiple users and actors, as well as present possibilities for alternative and diversified uses and activities. This might underline the hypothesis that future cities will be governed in less formalised ways, and that urban forms will be created through spontaneous, temporary, mobile, and adaptive negotiation processes.01A - Beitrag in wissenschaftlicher Zeitschrift

- PublikationUrbane Nachbarschaft – Raum des Alltäglichen, Ressource und Interventionsebene(Springer, 2022) Tappert, Simone; Drilling, Matthias; Tappert, Simone; Schnur, Olaf; Käser, Nadine; Oehler, Patrick [in: Nachbarschaften in der Stadtentwicklung. Idealisierungen, Alltagsräume und professionelles Handlungswissen]Die Frage nach den Potenzialen von Nachbarschaften gewinnt derzeit wieder an Bedeutung. Gründe dafür liegen unter anderem in der zunehmenden Unübersichtlichkeit infolge von Pluralisierungs- und damit verbundenen Ausdifferenzierungsprozessen. Die Planung und Steuerung von Städten folgt heute keinem kategorischen Imperativ mehr, verortet sich in Hyperdynamiken und erfordert von Expert*innen aus den unterschiedlichen Handlungsfeldern die Fähigkeit, mit Mehrdeutigkeiten und Unsicherheiten umzugehen. Im Suchprozess nach geeigneten Interventionsebenen werden Nachbarschaften als stabile „Keimzellen“ der Lebenswelt konstruiert, und die Reduktion auf überschaubare sozialräumliche und territoriale Ausschnitte suggeriert Berechenbarkeit und Planbarkeit. Der Beitrag durchbricht dieses Verständnis und konzeptualisiert Nachbarschaften als etwas Situatives, Kontextabhängiges und Prozessuales, das auf der Basis eines gemeinsam geteilten Raumes durch menschliches Handeln im Alltag entsteht. Nähe und Distanz, Annäherung und Abgrenzung, sowie Ideale des Mit- und Nebeneinanders in städtischen Räumen werden dabei am geteilten Wohnort kontinuierlich verhandelt. Nachbarschaft aus einer alltagstheoretischen Perspektive zu konzeptualisieren, soll dabei eine Unter- und Überschätzung des lokalen Potenzials von „Nachbarschaft“ in der Stadtentwicklung sichtbar machen.04A - Beitrag Sammelband
- PublikationValidity of Ambient Levels of Fine Particles as Surrogate for Personal Exposure to Outdoor Air Pollution—Results of the European EXPOLIS-EAS Study (Swiss Center Basel)(Taylor & Francis, 27.12.2011) Bayer-Oglesby, Lucy; Künzli, Nino; Röösli, Martin; Braun-Fahrländer, Charlotte; Mathys, Patrick; Stern, Willem; Jantunen, Matti; Kousa, Anu [in: Journal of the Air & Waste Management Association]To evaluate the validity of fixed-site fine particle levels as exposure surrogates in air pollution epidemiology, we considered four indicator groups: (1) PM2.5 total mass concentrations, (2) sulfur and potassium for regional air pollution, (3) lead and bromine for traffic-related particles, and (4) calcium for crustal particles. Using data from the European EXPOLIS (Air Pollution Exposure Distribution within Adult Urban Populations in Europe) study, we assessed the associations between 48-hr personal exposures and home outdoor levels of the indicators. Furthermore, within-city variability of fine particle levels was evaluated. Personal exposures to PM2.5 mass were not correlated to corresponding home outdoor levels (n = 44, rSpearman (Sp) = 0.07). In the group reporting neither relevant indoor sources nor relevant activities, personal exposures and home outdoor levels of sulfur were highly correlated (n = 40, rSp = 0.85). In contrast, the associations were weaker for traffic (Pb: n = 44, rSp = 0.53; Br: n = 44, rSp = 0.21) and crustal (Ca: n = 44, rSp = 0.12) indicators. This contrast is consistent with spatially homogeneous regional pollution and higher spatial variability of traffic and crustal indicators observed in Basel, Switzerland. We conclude that for regional air pollution, fixed-site fine particle levels are valid exposure surrogates. For source-specific exposures, however, fixed-site data are probably not the optimal measure. Still, in air pollution epidemiology, ambient PM2.5 levels may be more appropriate exposure estimates than total personal PM2.5 exposure, since the latter reflects a mixture of indoor and outdoor sources.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationValidity of Annoyance Scores for Estimation of Long Term Air Pollution Exposure in Epidemiologic Studies. The Swiss Study on Air Pollution and Lung Diseases in Adults (SAPALDIA)(Oxford University Press, 01.07.2000) Bayer-Oglesby, Lucy; Künzli, Nino; Monn, Christian; Schindler, Christian; Ackermann-Liebrich, Ursula; Leuenberger, Philippe [in: American Journal of Epidemiology]In air pollution epidemiology, estimates of long term exposure are often based on measurements made at one fixed site monitor per area. This may lead to exposure misclassification. The present paper validates a questionnaire-based indicator of ambient air pollution levels and its applicability to assess their within-area variability. Within the framework of the SAPALDIA (Swiss Study on Air Pollution and Lung Diseases in Adults) cross-sectional study (1991), 9,651 participants reported their level of annoyance caused by air pollution on an 11-point scale. This subjective measure was compared with annual mean concentrations of particulate matter less than 10 μm in diameter (PM10) and nitrogen dioxide. The impact of individual factors on reported scores was evaluated. Nitrogen dioxide concentrations at home outdoors (measured in 1993), smoking, workplace dust exposure, and respiratory symptoms were found to be predictors of individual annoyance scores. Regression of population mean annoyance scores against annual mean PM10 and nitrogen dioxide concentrations (measured in 1993 and 1991, respectively) across areas showed a linear relation and strong correlations (r > 0.85). Analysis within areas yielded consistent results. The observed associations between subjective and objective air pollution exposure estimates suggest that population mean scores, but not individual scores, may serve as a simple tool for grading air quality within areas. Reported annoyance due to air pollution should be considered an indicator for a complex environmental condition and thus might be used for evaluating the implementation of environmental policies.01A - Beitrag in wissenschaftlicher Zeitschrift
