The study was built on earlier work examining the effects of acidic fog on human subjects with asthma. Mouthpiece exposure studies on asthmatic subjects showed that both nitric and sulfuric acids potentiate the bronchoconstrictor effects of fog water, and that these acids appear to be similar in this respect. The work resulted in the exposure chamber at the University of California, San Francisco being extensively modified, based on improvements recommended in an earlier investigation, thus allowing human subjects to be exposed to rigorously controlled and monitored test fogs. The study used the chamber to first examine the effects of fog without acid, and then the effects of fog with acid, on exercising subjects with asthma.
