Tobacco smoking remains an important public health issue worldwide. Assessment of exposure to tobacco-related toxicants and carcinogens at the population level is thus an essential population health indicator. This can be achieved by wastewater-based epidemiology (WBE), which relies on the analysis
Acute and subacute effects of tobacco alkaloids, tobacco-specific nitrosamines and phenethyl isothiocyanate on N'-nitrosonornicotine metabolism in rats.

N'-Nitrosonornicotine (NNN) was the first tobacco-specific nitrosamine (TSNA) identified as carcinogen in tobacco smoke, but no data exist on in vivo interactions between NNN and other tobacco alkaloids, TSNA or phenethyl isothiocyanate (PEITC) which have been demonstrated in various studies on
Levels of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) in raw wastewater as an innovative perspective for investigating population-wide exposure to third-hand smoke.

Tobacco smoking is the major cause of many chronic diseases, especially lung cancer. Knowledge about population-wide tobacco use and exposure is essential to characterise its burden on public health and evaluate policy efficacy. Obtaining such knowledge remains challenging with current methods

BACKGROUND
The minor alkaloids in tobacco play an important role in the chemical composition of cigarette smoke, and they are precursors of tobacco-specific nitrosamines (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), N-nitrosonornicotine (NNN), N-nitrosoanabasine (NAB) and N-nitrosoanatabine
