Lookout for Third-Hand Smoke

Business Week offers up an interesting story on third-hand smoke and its impact on the environment.

It focuses on studies that track the impact of third-hand smoke, defined perfectly by a doctor quoted in the story:

"We're talking here about compounds that were not originally emitted by cigarettes but that may form indoors as a result of the residue that settles indoors, after smoking, which then mixes with indoor chemistry," explained Hugo Destaillats, a chemist in the indoor environment department of Berkeley National Laboratory in California and a co-author of the study.
