Secondhand smoke exposure and other signs of tobacco consumption at outdoor entrances of primary schools in 11 European countries
'Elsevier BV', 2020Co-Authors: Henderson Elisabet, Continente Xavier, Fernández Esteve, Tigova Olena, Cortés-francisco Nuria, Gallus Silvano, Lugo Alessandra, Semple Sean, O'donnell Rachel, Clancy LukeAbstract:Introduction Although smoking restrictions at child-related settings are progressively being adopted, school outdoor entrances are neglected in most smoke-free policies across Europe. Objectives To describe secondhand smoke (SHS) exposure and tobacco-related signs in outdoor entrances of primary schools in Europe according to area-level socioeconomic status (SES), smoke-free policy, national smoking prevalence, and geographical region. Methods In this cross-sectional study we monitored vapor-phase nicotine concentrations at 220 school outdoor entrances in 11 European countries (March 2017–October 2018). To account for nicotine presence, we used the laboratory's limit of quantification of 0.06 μg/m3 as point threshold. We also recorded the presence of smell of smoke, people smoking, cigarette butts, and Ashtrays. Half of the schools were in deprived areas. We grouped countries according to their Tobacco Control Scale (TCS) score, smoking prevalence (2017–2018), and United Nations M49 geographical region. Results There were detectable levels of nicotine in 45.9% of the outdoor entrances, in 29.1% smell of smoke, in 43.2% people smoking, in 75.0% discarded butts, and in 14.6% Ashtrays. Median nicotine concentration was below the laboratory's limit of quantificatio

Secondhand Smoke Exposure and Other Signs of Tobacco Consumption at Outdoor Entrances of Primary Schools in Eleven European Countries
Dublin Institute of Technology, 2020Co-Authors: Henderson Elisabet, Continente Xavier, Fernández Esteve, Tigova Olena, Cortés-francisco Nuria, Gallus Silvano, Lugo Alessandra, Semple Sean, O\u27donnell Rachel, Clancy LukeAbstract:Introduction: Although smoking restrictions at child-related settings are progressively being adopted, school out-door entrances are neglected in most smoke-free policies across Europe. Objectives:To describe secondhand smoke (SHS) exposure and tobacco-related signs in outdoor entrances of primary schools in Europe according to area-level socioeconomic status (SES), smoke-free policy, national smoking prevalence, and geographical region. Methods:In this cross-sectional study we monitored vapor-phase nicotine concentrations at 220 school outdoor entrances in 11 European countries (March 2017–October 2018). To account for nicotine presence, we used the laboratory\u27s limit of quantification of 0.06μg/m3as point threshold. We also recorded the presence of smell of smoke, people smoking, cigarette butts, and Ashtrays. Half of the schools were in deprived areas. We grouped countries according to their Tobacco Control Scale (TCS) score, smoking prevalence (2017–2018), and United Na-tions M49 geographical region. Results:There were detectable levels of nicotine in 45.9% of the outdoor entrances, in 29.1% smell of smoke, in43.2% people smoking, in 75.0% discarded butts, and in 14.6% Ashtrays. Median nicotine concentration was below the laboratory\u27s limit of quantificationb0.06μg/m3(Interquartile range:b0.06–0.119). We found higher SHS levels in countries with lower TCS scores, higher national smoking prevalence, and in the Southern and East-ern European regions. People smoking were more common in schools from lower area-level SES and in countries with lower TCS scores (pb0.05). Conclusions: Smoking at school outdoor entrances is a source of SHS exposure in Europe. These findings support the extension of smoking bans with a clear perimeter to the outdoor entrances of schools

increasing the sensitivity of δ13c and δ15n abundance measurements by a high sensitivity elemental analyzer connected to an isotope ratio mass spectrometer
Rapid Communications in Mass Spectrometry, 2007Co-Authors: Thomas Hansen, Ulrich SommerAbstract:A common elemental analyzer system connected to a temperature-controlled gas chromatography (GC) column and coupled to an isotope ratio mass spectrometer was improved to decrease the determination limit for a simultaneous stable isotope ratio measurement of nitrogen and carbon dioxide. The additional use of a special Ashtray system to collect the combustion residuals permitted more time-efficient work. These modifications to the elemental analyzer allowed precise measurements to be made down to 1.5 µg nitrogen and 10 µg carbon for stable isotope analysis. Low system background values and an acceptable signal-to-noise ratio have made an additional blank correction for these low sample measurements unnecessary. We provide a precision of this stable isotope analysis for lowest amounts of 1.2–2 µg nitrogen with a standard deviation of ±0.496‰ (n = 27) and for 8.2–15 µg carbon with a standard deviation of ±0.257‰ (n = 31) across different sample runs under stipulated conditions. This application can be established in an automatic mode without cryofocusing procedures.
