Tobacco smoke, take three

摘要

The dangers of second-hand cigarette smoke are well known, but nicotine can linger on indoor surfaces and generate 'third-hand' smoke, either through its re-emission into the air or by direct ingestion from surfaces. Researchers have found that nicotine on surfaces can produce aerosols of potentially toxic oxidation products, by reacting with certain oxidizing gases when exposed to conditions typical of those found in the home.
