摘要

Background: Outdoor SHS exposure is often encountered in leisure and sport activities areas. AIMS: to evaluate SHS outdoor exposure METHOD: PM2.5 measurements with OPC, BC (Black Carbon) with Aethalometers, nicotine with passive samplers and GC. Procedures: Stadium: analyzers and nicotine samplers inside/outside. Pedestrian area: measurements on Friday to Monday in pedestrian area and in trafficked zones. City Parks: analyzers on park benches up/downwind smokers. Public Beach: BC analyzer up/downwind beach umbrellas. Outdoor smoking/indoor non smoking Disco Club: 3 days continuous measurements. RESULTS: Stadium: BC, PM2.5, nicotine outside: 2.1, 6.2, and 0.12 μg/m3 , inside during game: 3.1, 13.9, 3.16 μg/m3, respectively (p ＜ 0.005). Pedestrian area: quiet hours pedestrian area: 2.8, and 35.4, rush hours: 4.1 and 64.9 μg/m3 respectively. (p=0.001). Quiet hours trafficked area: 3.7, 30.4 and 4.8, 31.8 μg/m3 rush hours for BC and PM2.5 respectively. Nicotine:＜ 0.02 g/m3 in trafficked area and 0.26 μg/m3 in pedestrian area. City parks: BC bckg 5.1, near smokers 12.6μg/m3(p=＜0.001). PM2.5 bckg 16.6, near smokers 17.8(p= 0.039). Public beach: BC:0.8 and 1.5μg/m3 up/downwind respectively(p=＜0.001). Disco Club: summer outdoor: BC bckg 9.0μg/m3, during Disco activity 30.3μg/m3. PM2.5 bckg: 26.4μg/m3, Disco activity: 85.5μg/m3. Nicotine.: 0.67μg/m3. Winter indoor: BC bckg 2.5μg/m3, Disco activity 13.2μg/m3. PM2.5 bckg:33.6μg/m3, during Disco activity: 122.6μg/m3, Nicotine: 0.83μg/m3. BC lower in Winter but not PM2.5 because of indoor fireworks. Nicotine, higher in winter indicating illegal smoking but with lower impact on air quality than in summer. CONCLUSION: Leisure and sport facilities outdoor air quality heavily compromised by smoking activity. Increase of several epidemiological change units for BC and PM2.5 observed in all places due to SHS with concern for short and long-term health consequences.
