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

Another reason for including asthma on the list of potential health risks posed by secondhand tobacco smoke, especially for non-smokers, has been uncovered. Furthermore, the practice of using ozone to remove the smell of tobacco smoke from indoor environments, including hotel rooms and the interiors of vehicles, is probably a bad idea.

A new study by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) shows that ozone can react with the nicotine in secondhand smoke to form ultrafine particles that may become a bigger threat to asthma sufferers than nicotine itself. These ultrafine particles also become major components of thirdhand smoke - the residue from tobacco smoke that persists long after a cigarette or cigar has been extinguished.

"Our study reveals that nicotine can react with ozone to form secondary organic aerosols that are less than 100 nanometers in diameter and become a source of thirdhand smoke," says Mohamad Sleiman, a chemist with the Indoor Environment Department of Berkeley Lab's Environmental Energy Technologies Division (EETD) who led this research.

"Because of their size and high surface area to volume ratio, ultrafine particles have the capacity to carry and deposit potentially harmful organic chemicals deep into the lower respiratory tract where they promote oxidative stress," Sleiman says. "It's been well established by others that the elderly and the very young are at greatest risk."

Results of this study have been reported in the journal Atmospheric Environment in a paper titled "Secondary organic aerosol formation from ozone-initiated reactions with nicotine and secondhand tobacco smoke." Co-authoring this paper with Sleiman were Hugo Destaillats and Lara Gundel, also with EETD's Indoor Environment Department, and Jared Smith, Chen-Lin Liu, Musahid Ahmed and Kevin Wilson with the Chemical Dynamics Group of Berkeley Lab's Chemical Sciences Division. The study was car
