Second hand smoke (SHS) introduces thousands of toxic chemicals into the lung, including carcinogens and oxidants, which cause direct airway epithelium tissue destruction. It can also illicit indirect damage through its effect on signaling pathways related to tissue cell repair and by the abnormal induction of inflammation into the lung. After repeated exposure to SHS, these symptoms can lead t...
Objective: To investigate exposure of children to second hand smoke (SHS) in cars under real life smoking and realistic driving conditions. Methods: PM2.5 concentrations (particulate matter with an aerodynamic diameter below 2.5μm) were monitored as a marker for SHS in 21 car journeys using the TSI portable photometer SidePakTM. Five participants (includ ing one non-smoker) volunteered to drive...
BACKGROUND Because they have chronic airway inflammation, adults with asthma could have symptomatic exacerbation after exposure to second hand smoke (SHS). Surprisingly, data on the effects of SHS exposure in adults with asthma are quite limited. Most previous epidemiological studies used self-reported SHS exposure which could be biased by inaccurate reporting. In a prospective cohort study of ...
Smoking in hospitals is banned in many European countries; nevertheless, the level of compliance is diverse, and, in some cases, smoking areas remain. The present study describes the levels of second-hand smoke, as derived from respirable suspended particle measurements, in a sample of European hospitals during the year 2007. The present study was a multicentric descriptive cross-sectional stud...
