To better understand the indoor fate of nicotine, these parameter  effects on its sorption, desorption, and oxidation rates were investigated on  model indoor surfaces that included fabrics, wallboard paper, and wood  materials. Nicotine sorption under dry conditions was enhanced by higher SA and  higher polarity of the substrate. Interestingly, nicotine sorption to cotton and  nylon was facilitated by increased RH, while sorption to polyester was hindered  by it. Desorption was affected by RH, AER, and surface type. Heterogeneous  nicotine-ozone reaction was investigated by Fourier transform infrared  spectrometry with attenuated total reflection (FTIR-ATR), and revealed a pseudo  first-order surface reaction rate of 0.035 +/- 0.015 min(-1) (at [O(3)] = 6 +/-  0.3 x 10(15) molecules cm(-3)) that was partially inhibited at high RH.  Extrapolation to a lower ozone level ([O(3)] = 42 ppb) showed oxidation on the  order of 10(-5) min(-1) corresponding to a half-life of 1 week. In addition,  similar surface products were identified in dry and high RH using gas  chromatography-mass spectrometry (GC-MS). However, FTIR analysis revealed  different product spectra for these conditions, suggesting additional  unidentified products and association with surface water. Knowing the indoor  fate of condensed and gas phase nicotine and its oxidation products will provide  a better understanding of nicotine's impact on personal exposures as well as  overall indoor air quality.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">35</style></issue></record></records></xml>
