    Living 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
    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.

    PM2.5 assessment in 21 European study centers of ECRHS II: method and first winter results
    (Taylor & Francis, 2003) Hazenkamp-von Arx, Marianne E.; Fellmann, Thomas Götschi; Bayer-Oglesby, Lucy; Ackermann-Liebrich, Ursula; Gíslason, Thórarinn; Heinrich, Joachim; Jarvis, Deborah; Luczynska, Christina; Manzanera, Angeles Jaén; Modig, Lars; Norbäck, Dan; Pfeifer, Annette; Poli, Albino; Ponzio, Michela; Soon, Argo; Vermeire, Paul; Künzli, Nino
    The follow-up of a cohort of adults from 29 European centers of the former European Community Respiratory Health Survey (ECRHS) I (1989–1992) will examine the long-term effects of exposure to ambient air pollution on the incidence, course, and prognosis of respiratory diseases, in particular asthma and decline in lung function. The purpose of this article is to describe the methodology and the European-wide quality control program for the collection of particles with 50% cut-off size of 2.5 µm aerodynamic diameter (PM2.5 ) in the ECRHS II and to present the PM2.5 results from the winter period 2000–2001. Because PM2.5 is not routinely monitored in Europe, we measured PM2.5 mass concentrations in 21 participating centers to estimate background exposure in these cities. A standardized protocol was developed using identical equipment in each center (U.S. Environmental Protection Agency Well Impactor Ninety-Six [WINS] and PQ167 from BGI, Inc.). Filters were weighed in a single central laboratory. Sampling was conducted for 7 days per month for a year. Winter mean PM2.5 mass concentrations (November 2000–February 2001) varied substantially, with Iceland reporting the lowest value (5 µg/m3) and northern Italy the highest (69 µg/m3). A standardized procedure appropriate for PM2.5 exposure assessmnt in a multicenter study was developed. We expect ECRHS II to have sufficient variation in exposure to assess long-term effects of air pollution in this cohort. Any bias caused by variation in the characteristics of the chosen monitoring location (e.g., proximity to traffic sources) will be addressed in later analyses. Given the homogenous spatial distribution of PM2.5 , however, concentrations measured near traffic are not expected to differ substantially from those measured at urban background sites.
