Abstract
The dynamics of nicotine in an indoor environment can be greatly affected by building parameters (e.g. relative humidity (RH), air exchange rate (AER), and presence of ozone), as well as surface parameters (e.g. surface area (SA) and polarity). To better understand the indoor fate of nicotine, these parameter effects on its sorption, desorption, and oxidation rates were investigated. Nicotine was found to preferably sorb to high SA/high polarity materials. Interestingly, RH was shown to enhance both nicotine sorption and desorption on and from cellulose. Desorption was also affected by AER and surface smoothness. Nicotine-ozone surface reactions revealed similar GC-MS identified surface products in dry and high RH. However, dissimilar FTIR product spectra suggested unidentified products and possible water interactions. This surface reaction rate was partially inhibited at high RH. 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.
