Passive Smoking Raises Carcinogen Levels In Urine Rapidly
NKK = 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone
You can read about this study in the American Journal of Public Health.
The researchers measured urine levels of 84 non-smoking bartenders and restaurant workers in Oregon. 52 of them did one shift in a no smoking bar/restaurant, while the others worked a shift where smoking was allowed.
NKK is only ever found in a person who either smokes or breathes other people's smoke.
The participants gave urine samples before and immediately after their shifts. Stark and team found that 75% of the participants who had worked in an establishment where smoking was allowed had some detectable level of NKK. The team also found that levels went up for each hour worked.
Stark and team suggest that this new study provides more evidence that passive smoking is hazardous to health and that people should be protected.
Secondhand smoking = Passive smoking (breathing in the smoke of other smokers, while not smoking a cigarette, cigar or pipe yourself)
