Description:
Analytical methods were validated to determine polycyclic aromatic hydrocarbons (PAH) and other semivolatile organic compounds in house dust. e also examined the storage stability of three potential markers (solanesol, nicotine, and continine) for particulate-phase environmental tobacco smoke (ETS) in house dust. he results showed that less than 10 percent of the spiked solanesol was recovered from the dust after storage for 7 days in a typical indoor environment (room temperature and indoor lighting). nder the same storage conditions, after 21 days of storage, more than 90 percent of the continine and approximately 40 percent of the nicotine were recovered. hese findings suggest that cotinine is a better marker for ETS particles in house dust than nicotine, whereas solanesol is not a suitable marker. mall field study was conducted to evaluate the role of smokers in the house on the levels of PAH, cotinine, and nicotine present in house dust. amples were collected from eight houses, using the High Volume Small Surface Sampler (HVS3) to collect carpet-embedded dust from designated areas in the carpet in either the living room or family room of each house. fter collection, the dust samples were separated into fine (150 um) and coarse fractions. ost of the dust loading (69-85 percent) was found to be distributed in the fine fraction. he fine dust samples were analyzed for PAH, nicotine, and cotinine.
