Abstract: Smoking has long been recognized as a hugely serious public health issue. The effects of secondhand smoke have been attached great attention by health agencies worldwide over the past decades. A new risk of tobacco smoke exposure, thirdhand smoke (THS), has been identified in recent years. Tobacco-specific nitrosamines (TSNAs) are generated by chemical reactions between THS and common air pollutants, which are characterized as a carcinogenic group of substances. Public health has started to consider TSNAs as a new source of environmental pollutant. Even though a small number of studies has begun investigating TSNAs from THS in a variety of contexts and testing its possible health effects, the toxicity of THS and how TSNAs impact on health are still under investigation. The objective of this essay is to review existing evidence on TSNAs and health implication for TSNAs, focusing on how THS differs from secondhand smoke, current evidence regarding the formation of TSNAs and its potential health impacts and addressing possible assessments for THS exposure.
