Identifying and quantifying secondhand smoke in multiunit homes with tobacco smoke odor complaints

摘要: Abstract Accurate identification and quantification of the secondhand tobacco smoke (SHS) that drifts between multiunit homes (MUHs) is essential for assessing resident exposure health risk. We collected 24 gaseous particle measurements over 6–9 day monitoring periods in five nonsmoking MUHs with reported SHS intrusion problems. Nicotine tracer sampling showed evidence all during period; logistic regression chemical mass balance (CMB) analysis enabled some precise entry. Logistic models identified eight when residents complained odor, CMB provided estimates magnitude six these periods. Both approaches properly or apportioned cooking used as no-SHS controls. Finally, both and/or apportionment suspected additional did not report smelling smoke. The time resolution this methodology goes beyond methods involving single tracers (such nicotine), enabling duration intrusion, which accurate assessment human exposure.
