Berkeley study shows ozone and nicotine a bad combination for asthma
Date:8/16/2010

ried out under a grant from the University of California's Tobacco-Related Disease Research Program.

The dangers of mainstream and secondhand tobacco smoke, which contain several thousand chemical toxins distributed as particles or gases, have been well documented. This past February, a study, also spearheaded by Sleiman, Destaillats and Gundel, revealed the potential health hazards posed by thirdhand tobacco smoke which was shown to react with nitrous acid, a common indoor air pollutant, to produce dangerous carcinogens. Until now, however, in terms of forming ultrafine particles, there have been no studies on the reaction of nicotine with ozone.

Released as a vapor by the burning of tobacco, nicotine is a strong and persistent adsorbent onto indoor surfaces that is released back to indoor air for a period of months after smoking ceased. Ozone is a common urban pollutant that infiltrates from outdoor air through ventilation that has been linked to health problems, including asthma and respiratory ailments.

Says co-author Gundel, "Not only did we find that nicotine from secondhand smoke reacts with ozone to make ultrafine particles a new and stunning development but we also found that several oxidized products of ozone and nicotine have higher values on the asthma hazard index than nicotine itself."

Says co-author Destaillats, "In our previous study, we found that carcinogens were formed on indoor surfaces, which can lead to exposures that are likely to be dominated by dermal uptake and dust ingestion. This study suggests a different exposure pathway to aged secondhand or thirdhand smoke through the formation and inhalation of ultrafine particles. Also, our group had previously described the formation of secondary organic aerosols in reaction of indoor ozone with terpenoids, commonly present in household products. But this is the first time that nicotine has been tagged as a potential candidate to form ultrafine particles o
